REPORT OF WORKING PARTY 8A MEETINGOCTOBER 29 – NOVEMBER 7, GENEVA, SWITZERLAND

R8A/73 from the Director of the RB (Radiocommunications Bureau notes IPR statements which have been filedregarding new recommendations in WP 8A (Table 1, next page).

DRAFTING GROUP 8A-1, PAGING

The meeting report is 8A/TEMP/55 . The chair is B. Bulawka, USA. The Question under study is Question 12.

R8A/30 , Proposed Amendments to the Recommendation ITU-R M.539-3 - Technical and OperationalCharacteristics of International Radio-Paging Systems (Japan), proposes to add a new Annex 3 on the FLEX-TDhigh-speed radio paging system to Recommendation ITU-R M-539-3.

FLEX-TD is a national standard in Japan (RCR Standard STD-43 Rev. A). FLEX-TD was standardized by theAssociation of Radio Industries and Businesses (ARIB), the recognized and accredited standard setting body in Japan.In standardizing FLEX-TD, ARIB conducted over several years an open and comprehensive peer review of the FLEX-TD technology, including disclosure of intellectual property rights (IPR). Revision A of RCR STD-43 waspublished on 25 June 1996. IPR in RCR Standard STD-43 Rev. A has been disclosed to DG 8A-1.

R8A/30 was reviewed and information was added on system architecture, network aspects, and internationalroaming. Extensive technical discussions in DG 8A-1 were facilitated and advanced by the presence of the chairmanof ETSI’s Res 4 Committee on Radio Paging and technical experts on FLEX.

DG 8A-I was not able to come to a consensus view on recommended action to WP 8A on 8A/TEMP/ 54 ,Technical and Operational Characteristics of International Radio-Paging Systems, Draft Amendments to Rec. M.539-3. 8A/TEMP/54 adds the technical and operational characteristics of FLEX-TD as Annex 3 of M.539-3. Mostdelegations were of the view that 8A/TEMP/54 was consistent with Recommendation ITU-R

M.539-3 and that it should be sent to Study Group 8. Two delegations, while acknowledging the technicalcompleteness of 8A/TEMP/54 , were of the view that elements of 8A/TEMP/54 did not fully comply with theirview of the original intention of the Recommendation.

DG 8A-1 reviewed Report ITU-R M.900-2 (Radio-Paging Systems, Standardization of code and format) inconjunction with Recommendation ITU-R M.584-1 (Standard Codes and Formats for International Radio Paging,8A/TEMP/47), and concludes that:

• Relevant material on Radio-Paging Code No, 1 (POCSAG) should be extracted from Report ITU-R M-900-2 andplaced in a modified Recommendation ITU-R M.584-1;

• Report ITU-R M.900-2 should be deleted;• Recommendation ITU-R M.584-1 should be edited to reflect that it considers Radio Paging Code #1;• Recommendation ITU-R M.584-1 should reference Recommendation ITU-R M.539-3 which will contain the

latest, updated system developments in international radio-paging.

DG 8A-1 notes that Report ITU-R M.900-2 contains two references to IPR. One statement is by the UKAdministration on behalf of the Post Office Code Standardization Advisory Group (POCSAG) and the other refers toBritish Telecom. These may need to be updated.



DG 8A-1 recommends that Working Party 8A approve 8A/TEMP/47 , proposing modifications toRecommendation ITU-R M.584-1, and forward 8A/TEMP/47 to Study Group 8 for approval.

DRAFTING GROUP 8A-2, AUTOMATIC DETERMINATION OF LOCATION AND GUIDANCE INTHE LAND MOBILE SERVICES

The meeting report is 8A/TEMP/34 . The chair is M. Wolf, USA. He was the only participant to attend themeeting. The Question under study is Question 51.

The Drafting Group reviewed 8A/TEMP/10 . It is a combination of R8A/35 (Preliminary Draft NewRecommendation: Automatic Determination of Location and Guidance in the Land Mobile Services) and R8A/37(Proposed Addition to Preliminary New Recommendation - Digitally Coded Speech in the Land Mobile Service).R8A/35 provides requirements and a tutorial on Automatic Determination of Location systems. R8A/37describes the TIA IS-641 Enhanced Full Rate codec used in IS-136 (D-AMPS, TDMA) systems. The DraftingGroup did final editorial work on the document and recommends that it be sent forward by the Working Party forapproval as a Recommendation.

DRAFTING GROUP 8A-3,DIGITALLY CODED SPEECH

The meeting report is 8A/TEMP/22 . The chair is Y. Sugamara, Japan. The Question under study is Question101.

Drafting Group 8A-3 reviewed the documents assigned by the Plenary:R8A/36 , Proposed Addition to Preliminary New Recommendation - Digitally Coded Speech in the Land Mobile

Service (USA). This is TIA IS-96-B variable rate CELP speech codec used in IS-95 US CDMA cellular systems.R8A/37 , Proposed Addition to Preliminary New Recommendation - Digitally Coded Speech in the Land Mobile

Service (USA). This is TIA IS-641 Enhanced Full Rate codec used in TIA IS-136 (D-AMPS, TDMA) UScellular systems.

R8A/38 , Proposed Addition to Preliminary New Recommendation - Digitally Coded Speech in the Land MobileService (USA). This is TIA IS-127 Enhanced Variable Rate Codec used in IS-95 US CDMA cellular systems.

R8A/49 , Proposed Addition to Preliminary New Recommendation - Digitally Coded Speech in the Land MobileService (Nokia). This is the ETSI GSM Enhanced Full-Rate codec based on ACELP. It is identical to the USPCS 1900 EFR codec.

R8A/61 , Preliminary Draft New Recommendation ITU-R [8A/XD] - Digital Coded Speech in the Land MobileService. This is a new VSELP codec (draft Recommendation ITU-R M.[8A/XB]) based on the Canadian DIMRSsystem.

In accordance with Plenary direction, the table part of R8A/43 (Progress Report on Digitally Coded Speech in theLand Mobile Services), Annex 1 was updated to include all the above codecs. The main revisions to R8A/43Annex 1 are as follows:• Redefining Codec Delay into two parameters, Algorithmic Codec Delay and Total Codec Delay;• Adding two footnotes to Quality (MOS);• Splitting the D-AMPS column into two columns, D-AMPS [Full rate] and D-AMPS [Enhanced];• Splitting the CDMA column into two columns, CDMA [IS-96] and CDMA [IS-127];• Adding some missing rates;• Modifying rates after verification.

The Drafting Group prepared a revised working document (R8A/TEMP/023 and Corrigendum 1) towards adraft new Recommendation for consideration of Working Party 8A.

SUB-WORKING GROUP 8A-4, SHARING BSS (BROADCASTING-SATELLITE SERVICE)-SOUND

The meeting report of the Sub-Working Group is 8A/TEMP/5 . The chair is H. Prins, Austria. The Questionunder study is Question 106.

At WARC-92, bands 1452-1482; 2310-2360; 2535-2655 MHz were allocated to BSS (Sound) and are also allocatedto Land Mobile Service (LMS). SWG 8A-4 considered inputs concerning threshold levels required to coordinatebetween BSS and LMS. R8A/31 , Proposed Draft New Recommendation - Threshold Levels for Determining theNeed to Coordinate Between the BSS (Sound) and the Land Mobile Service in the Band 1 - 3 GHz (Japan), proposesthat the threshold for determining the need for coordination between satellite BSS (Sound) systems and LMS



receiving stations corresponds to a power-flux density (pfd) of -150 dB(W/m2/4kHz). The related liaison statementfrom WP 10-11S (R8A/62 , Reply to the Liaison Statement from WP 8A to WP 10-11S Regarding Studies OnSharing Between MS and BSS [Sound]) notes that -150 dB(W/m2/4kHz) is significantly below the typical pfdrequirements of BSS (Sound), which require pfd levels between -122 and -139dBW/m2/4kHz, and thereforecoordination will be required, based on this proposed pfd threshold level, in all cases. Note these pfd values areconfirmed only in the frequency band around 1 to 1.5 GHz.

Twelve delegates from seven administrations considered changes to the proposed draft new Recommendation whichwas submitted as Annex 1 to R8A/31 in an attempt to address concerns expressed by some administrations that theproposed draft new Recommendation did not fully reflect the purpose of Q.106/8.

Specifically some delegates wanted the proposed new draft Recommendation to reflect sharing issues between LMSand BSS in addition to just protection of LMS. This issue of sharing was also raised in the liaison statement fromWP 10-11S (R8A/62).

The Japanese Administration delegates were agreeable to the inclusion of protection criteria for BSS in the case ofinterference from LMS, and it was resolved to form a small Drafting Group under the guidance of Trinidad andTobago to draft a liaison statement from WP 8A to WP 10-11S with the intent of obtaining the technicalinformation related to the protection of BSS from LMS.

A draft liaison statement has been completed (8A/TEMP/004) and distributed to the interested delegations. Theyhave all responded positively. 8A/TEMP/045 is the Preliminary Draft New Recommendation [8A/XXX] -Threshold Levels for Determining the Need to Coordinate Between the Broadcasting-Satellite Service (Sound) and theLand Mobile Services in the Band 1 - 3 GHz (Resolution 528) (Question 106/8).

It is anticipated that WP 10-11S will respond immediately after their next meeting, and that once the information isavailable from WP 10-11S, the proposed new draft Recommendation can be completed by WP 8A at its nextmeeting.

DRAFTING GROUP 8A-5, TRANSPORT INFORMATION AND CONTROL SYSTEMS (TICS)

The meeting report is 8A/TEMP/29 . The chair is P. Najarian, USA. The Question under study is Question 205.

Attachment 8 to Document R8A/1 is a Working Document towards a draft new Recommendation on TICS:objectives and requirements. R8A/44 (Proposed Revisions to Draft New Recommendation on TransportInformation and Control Systems [TICS]: Objectives and Requirements [Question ITU-R 205/8], Japan) andR8A/64 (TICS - Suggested Revisions to Attachment 8 to Doc. R8A/1 [Doc. 8A/TEMP/70], USA) were reviewedand incorporated into R8A/TEMP/30 , the proposed draft Recommendation on the objectives and basicrequirements of TICS. This was forwarded to WP 8A for approval. R8A/TEMP/30 identifies elements andrelated RF approaches used for vehicle control systems, traffic management, traveler information, publictransportation, fleet management, emergency management and electronic payment.

The Drafting Group reviewed and incorporated R8A/45 (Proposed Revisions to Working Document on TransportInformation and Control Systems [TICS]: Worldwide Developments and Experiences [Questions ITU-R 51/8 and205/8], Japan) and R8A/65 (Working Document On Transport Information and Control Systems [TICS]:Worldwide Developments and Experiences) into Attachment 9 to R8A/1 - a Working Document on TICS: worldwidedevelopments and experiences (8A/TEMP/26) . The intent of this document is to collect information on theworldwide activities on TICS, and to lay the groundwork for the future development of draft new Recommendationson the spectrum needs and traffic requirements of TICS.

Even though considerable progress has been accomplished during this meeting on this Working Document,additional information is still required prior to submission to WP 8A for approval. This also provides additionalopportunity to Administrations to further review the text with the objective of providing contributions, through theCorrespondence Group, between this meeting and the next meeting of WP 8A.

The objective of the work within ITU-R is to study the radiocommunication aspects of TICS including:• Basic characteristics and objectives• Radio based services• Spectrum requirements and band suitability• Interconnect requirements with the switched telecommunication networks• Technical factors affecting sharing between TICS and other users• The ability of evolving mobile telecommunication systems to deliver TICS services.



To accomplish these objectives, a number of draft new Recommendations will be proposed and developed:• Objectives and requirements of TICS;• Functionalities;• Spectrum needs;• Traffic and spectrum requirements;• TICS technologies.

Additional draft new Recommendations may be proposed, as necessary.

Two new Working Documents towards draft new Recommendations on TICS were proposed. Both WorkingDocuments were forwarded to the next Plenary Meeting of WP 8A for approval as Working Documents toward draftnew Recommendations. 8A/TEMP/038 is the Liaison Statement to ISO TC204 Transport Information andControl Systems (TICS) which includes copies of 8A/TEMP/26-30 .

8A/TEMP/28) relies on the objectives and requirements developed to map the relationship of TICS functions tosuitable RF options. It is important to develop a complete list of TICS functions in order to fully analyze the radioservice requirements. Annex 1 contains a proposed outline of the functionalities of TICS.

8A/TEMP/27 relies on the objectives and requirements developed to propose technologies. Annex 1 contains aproposed outline of the Recommendation on the technologies for TICS. Two examples are attached to this Annex:• Japan’s Vehicle Information and Communications System (VICS) Service;• Japan’s low power millimeter wave radar system for vehicle collision avoidance radar applications.

DRAFTING GROUP 8A-6,EVOLUTION TOWARDS IMT-2000

The meeting report is 8A/TEMP/33 . The chair is E.S. Ehrlich, USA. The Question under study is 208. TheDrafting Group met four times. A total of 21 participants representing 11 ITU-R M/members attended the meetings.The group considered:R8A/7, ITU-T Study Group 11 - Liaison Statement to Working Party 8A (Rec. ITU-R M.1073 & ITU-T Question

8/11) (WP 8D);R8A/16, Liaison Statement to Working Party 8A (TG 8-1);R8A/24, Evolution of Land Mobile Systems Towards FPLMTS/IMT-2000 - Progress Report;R8A/63 , Liaison Statement to ITU-R WP 8A - Framework for Modularity for IMT-2000/FPLMTS. This

describes a layer set of functions to support multiple radio technologies and mechanism Radio Bearer AdaptationFunction (RBAF which appears to be an etiquette, i.e., handshake) to negotiate between them. It also suggestsan Adaptation Functionality to negotiate with each different core network.

R8A/66 , Liaison Statement to Working Party 8A includes the draft Report On Evolution of Land Mobile SystemsToward IMT-2000/FPLMTS (October 25, 1996). This report supersedes the version sent in April (8A/16). Itincludes the comments from countries worldwide about their plans for IMT-2000. The comments do not suggesteasy agreement on common technologies or easy availability of common spectrum. The key features of IMT-2000 are a high degree of commonality of design worldwide, compatibility worldwide with radio and fixednetworks, high quality services and the use of a small pocket terminal worldwide.

The group developed additional text for the draft new Recommendation on Evolution of Land Mobile SystemsTowards FPLMTS (R8A/24), based on the input contributions. The primary source of text was R8A/66 . TheDrafting Group updated the draft Recommendation based on the revised text suggested by Task Group 8/1. Severalnew considering and recommends statements were added. In addition, the Drafting Group added new text from theTask Group 8/1 report on the Global IMT-2000 Vision into Section 3 of the draft new Recommendation. Theoutput of these efforts is 8A/TEMP/21R1 . 8A/ TEMP/21R1 provides objectives and requirements that focuson a very adaptable (bandwidth on demand) third generation system capable of coexistence and compatibility withexisting second generation technologies.

There is a strong desire to approve the draft new Recommendation as soon as possible in order to provide timelyguidance to pre-IMT-2000 systems which intend to evolve towards FPLMTS. The Drafting Group requests that WP8A approve the draft new Recommendation at this meeting, especially in light of the timing of the next StudyGroup 8 meeting in June and the subsequent Radiocommunication Assembly meeting. The group developed aliaison statement (8A/TEMP/20(Rev. 1)) which replies to the input liaisons from Task Group 8/1 (R8A/16,R8A/63, R8A/66 ) and ITU-T Study Group 11 (R8A/7) and requests comment on the draft new Recommendationfrom WP 8D and ITU-T Study Group 2.



The Drafting Group seeks guidance from WP 8A as to whether the draft Recommendation is mature enough to besubmitted to Study Group 8 for approval. If WP 8A decides not to approve the draft new Recommendation at thismeeting, it will result in a delay in the approval of the Recommendation by as much as two years. In this case, theDrafting Group requests the document be carried forward as a preliminary draft new Recommendation in the WP 8Ameeting report.

DRAFTING GROUP 8A-7,DISASTER COMMUNICATIONS

The meeting report is 8A/TEMP/31 . The chair is P. Rinaldo, USA. The Question under study is Question 209.

Drafting Group 8A-7 had one informal meeting of those interested in disaster communications, and agreed to submitthe text of R8A/32 (Working Towards a Draft New Recommendation - Improvement of Disaster Communicationin the Mobile, Amateur and Associated Satellite Services [Question ITU-R 209/8], USA) to the next meeting of WP8A for approval as a TEMP document. This document indicates the basic issues of disaster preparedness: planning,cooperation among organizations, exercises and drills, reporting and the use of amateur services support. Oneadministration suggested adding Annexes that would describe disaster communications in a country or region.8A/TEMP/15 was drafted as a Liaison Statement to invite additional text from Working Parties 8B, 8C and 8D.

DRAFTING GROUP 8A-8 RADIO LOCAL AREA NETWORKS (RLAN)

The meeting report is 8A/TEMP/7 . The chair is C. Bishop, UK. The Question under study is Question 212.

Drafting Group 8A-8 met to develop a draft new Recommendation on Radio Local Area Networks (RLAN).R8A/56 is the Working Document Towards Draft New Recommendation: Radio Local Area Networks (RLANs).Liaison statements from WP 9B (R8A/14, Liaison Statement to Working Party 8A, and R8A/20, Liaison Statementto Working Party 8A - Preliminary Draft New Recommendation - Radio-Frequency Signals Transport throughOptical Fibres) and the demarcation between SG 8, SG 9 and ISO were also discussed.

The matter of the demarcation between ITU-R and ISO regarding Radio LANs was raised. Mr. Hayes reported thathe had encountered resistance at an ISO meeting to an input document that included details of frequency for RLANs,because certain delegates felt that the matter of radio frequencies for RLANs should be the responsibility of the ITU.This led to a discussion on demarcation issues and with whom responsibility for particular issues should lie. It wasdecided to draft a liaison statement from WP 8A to ISO and IEEE (with a copy to WP 9B) that states the nature andscope of the proposed draft new Recommendation, in order that ISO be aware of the work being undertaken by theITU on RLANs and what aspects are being covered. The proposed liaison statement to the ISO/IEC JTC1/SC 6Project JTC 1.06.43.11 is contained in 8A/TEMP/8 . The proposed liaison statement to the IEEE LMSC (Project802) is contained in 8A/TEMP/9 .

The issue of demarcation between SG 9 and SG 8 regarding RLANs was also discussed. There appears to be someduplication between the work of WP 8A and the Recommendation contained in the WP 9B Iiaison statement(R8A/14). The Chair explained that the reason for the similarities between the Recommendations was because bothdocuments had originated from the same source (a report prepared by Res 10 on RLANs). The Chair also explainedthat while the WP 9B draft Recommendation deals with the fixed network aspects and operational characteristics ofRadio LANs, the intention behind the WP 8A draft Recommendation is to concentrate on the frequency managementaspects that will arise as a result of the envisaged wide spread adoption of mobile Radio LAN technology. This isreflected in the revision to the Recommendation in the working paper R8A/56 . R8A/56 lists ETS 300 435, ETS300 328, four types of HIPERLAN, three Japanese National Standards and IEEE 802.11. It was decided that in orderto concentrate the Recommendation on the frequency management matters relating to the mobile aspects of RLANoperation, it would be appropriate to delete the Annex relating to the operational characteristics and topologies ofRLANs. Such characteristics had already been covered in the WP 9B Recommendation. The liaison to WP 9B iscontained in 8A/TEMP/24 .

The Drafting Group decided to split the table within the working paper as suggested in R8A/39 (Inclusion of USRegulatory and Standardization Material in Working Document for Mobile Radio Local Area Networks, USA), sothat spectrum management and interoperability parameters are dealt with separately. This paper supports the additionof three unlicensed FCC Part 15 bands and provides additional information on IEEE 802.11 band used in the 2,400 -2,483.5 MHz band with some bandwidth restriction in Japan, France and Spain. It was thought that the inclusion ofa great number of different systems and parameters within one table would be confusing to readers.

The Drafting Group then discussed the proposed Recommendation.



The use of the term “unregulated” within recommends 1, was questioned. The Chair accepted that the term could betaken to mean that there were no controlling factors for RLAN equipment and that this was not the message hewished the Recommendation to convey. It was also pointed out that there was also a desire to make more spectrumavailable for private RLANs and it was requested that the Recommendation be revised accordingly. This point wasaccepted and recommends 1 has been revised in 8A/TEMP/6 .

The issue of the power limits, specified in recommends 2 at a 1 Watt maximum, was discussed; the Drafting Groupdecided that great variation in power limits between different systems operating in different countries, means that amore specific wording should be used. A footnote was added noting that private RLANs operating in licensed,coordinated frequency bands may operate at higher transmission powers.

The question was raised as to whether it was appropriate for the Recommendation to include a recommends on theallocation of spectrum for public RLAN systems on a primary basis. The Chair explained that it would be necessaryto differentiate between public and private RLANs, as in many countries public RLANs would be subject to someform of planned frequency regime, as in recommends 4; therefore, use of the unregulated private RLAN bands wouldnot be appropriate.

The Drafting Group agreed to send the working document to the next Plenary Meeting of WP 8A for approval, witha view to it becoming a draft new Recommendation. It was noted that the different spectrum management parameterswere not yet available for all administrations, so a request would be made in this document to other administrationsto provide spectrum management parameter details for inclusion in the appropriate Annex of the Recommendation.The revised working paper is 8A/TEMP/6 .

DRAFTING GROUP 8A-9 CHANNEL PLANNING

The meeting report is 8A/TEMP/40 . The chair is C. Bishop, UK. The goal of the drafting group was to decide ifa new question is needed on the subject of channel planning to accommodate new spectrally efficient technologies, orwhether existing questions relating to the adoption of such technologies could be either used directly, or modified forthat purpose.

R8A/57 , is a Proposal for a Preliminary Draft New Question and a Working Paper Towards a NewRecommendation for the Planning of Channels in the Land Mobile Service Between 30-470 MHz (UK). Thedrafting group decided that in order to help focus on the spectrum management issues relating to the implementationof new spectrally efficient technologies in LMR frequencies, it would be appropriate to draft a new question relatingsolely to such matters. It was further decided that certain elements of Questions 7 and 37 could be used within thenew question and that it would be necessary to revise those questions accordingly to avoid duplication. The new andrevised questions are contained in 8A/TEMP/51 . The revised version of Question 7-4/8 also appears in8A/TEMP/43 , and the revised version of Question 37-3/8 appears in 8A/TEMP/44 .

The drafting group also discussed the proposed working paper towards a draft new recommendation. It was decided tocombine the working paper that appears as attachment 8 to R8A/l, with relevant parts of R8A/57 to produce aworking paper that can be taken forward to the next WP 8A meeting. The draft working paper is 8A/TEMP/42 .It proposes the introduction of more spectrally efficient technology in LMR bands. It provides details of the analysis(re-farming only without a change in trunking) of average peak hour loading that was done for metropolitan TorontoCanada proposal and also a European proposal done by ETSI CEPT Project Team SE23 to consider the technicalimplications of various options for future channeling arrangements (TETRA and CEPT T/R 25-08).

DRAFTING GROUP 8A-10,WIRELESS ACCESS LOCAL LOOP (WLL)

The meeting report is 8A/TEMP/46 . The chair is J.M. Costa, Canada. DG 8A-10 is studying a new Question onWireless Access Local Loop. The group met three times with an attendance of about 20 participants.

The first priority of the Drafting Group was the preparation of a draft new Question on the subject of wireless accesslocal loop systems. The draft new Question is given in 8A/TEMP/48 , Frequency Bands Technical Characteristics,and Operational Requirements for Wireless Access Local Loop Systems.

Drafting Group 8A-10 also considered the organizational structure which could be suitable for wireless access studies.They concluded that, ideally, all wireless access studies should be conducted within a single Study Group if possible,otherwise they should be conducted in a joint task group of SG 4, SG 8 and SG 9. It was also noted that thestructure should be designed to optimize the availability of expertise to carry out the work.



Based on R8A/28 from Canada (Working Document Towards a Draft New Recommendation on Suitable FrequencyBands for Wireless Access Local Loop), the Drafting Group created a new working document (8A/TEMP/49 ).This document notes the bands that may be utilized for fixed wireless access currently range from 450 MHz (TACS)to 40 GHz (LMCS/LMDS, Local Multipoint Communications/Distribution System). 8A/TEMP/49 is to becarried forward to the next meeting of WP 8A.

8A/TEMP/50 , a liaison statement to WPs 4A, 8B, 8C, 9A, 9B and 9D, has been prepared to inform these WPs ofthe proposed new Question and request information on technical characteristics and sharing criteria related to systemsoperating in frequency bands being considered for the implementation of wireless access local loop systems.

Priority was placed on the development of Volume 1 (Wireless Access Local Loop Systems: Basic Principals andSystem Descriptions) of the Handbook. The editing group on Volume 1 met throughout the meeting of WP 8A andwas successful in completing the work on this Volume (8A/TEMP/53). The approved new text for Volume 1with all editorial changes will be provided directly to the Secretariat.

8A/TEMP/001 is the list of contents of the Land Mobile Handbook. With regard to the other sections of theLand Mobile Handbook, considerable effort is required to complete these sections. 8A/TEMP/056 is the NewDraft Text Toward Section 10 and Annex B Cordless Telephone and Cordless Telecommunication Systems whichdescribes the Personal Handy phone System (PHS). The milestone for the completion of the balance of theHandbook is the end of June 1997. The status of the various sections of the Handbook is provided in8A/TEMP/58 .

DRAFTING GROUP 8A-12, SHARING MOBILE SATELLITE SERVICE

The meeting report is 8A/TEMP/36 . The chair is T. Ewers, Germany. Dr. K. Kosaka was appointed as liaisonfrom WP 8A to WP 8D.

The documents considered included:• Statements from Working Party 8D in Documents R8A/21, Coordination between Non-GSO Land Earth Stations

and Land Mobile Systems, R8A/6, Liaison Statement to Working Party 8A - Coordination Between Non-GSOLand Earth Stations and Land Mobile Systems;

• The liaison reply of R8A/26 (Land Mobile Service Below I GHz, WP 8A Rapporteur);



• Two new Contributions: R8A/33 , Progress Report from the WP 8D Rapporteurs’ Group for Preparation of theCPM-97 Report, and R8A/41 , Technical Characteristics of Certain Analog and Digital Private Land MobileRadio Equipment Operating Between 136 and 1,000 MHz, USA.

R8A/41 includes excerpts from TIA-603 for analog FM systems and TIA-TSB-102.CAAB used in the Project 25system on terrestrial land mobile spectrum sharing interference criteria and receiver parameters. R8A/33 providesconsiderable technical and tutorial information on spectrum sharing issues including Dynamic Channel AssignmentTechniques.

In addition two Japanese contributions were discussed: R8A/47 , Frequency Sharing Study Between Non-GSO MSSEarth-to-Space Links and the Land Mobile Service in the 148-150.05 MHz, and R8A/48 , A Methodology forCalculating Interference Probability from Non-GSO MSS Earth Station to Land Mobile Station Operating Below 1GHz. The Chair of Drafting Group 8A-12 participated in two meetings of Sub-Working Group 8D3A-4, which dealtwith the same documents as well, because they were also distributed to 8D. There are ongoing discussions on themethodology used in the contributions and there will be a liaison statement of Working Party 8D to 8A containingthe results of these discussions with a request to comment. Drafting Group 8A-12 therefore recommends WorkingParty 8A to take note of the Japanese contributions and to invite the administrations to comment on them before thenext meeting of Working Party 8A.

DRAFTING GROUP 8A-13,LIAISON STATEMENTS

The meeting report is 8A/TEMP/11 . The chair is P. Rinaldo, USA.

Drafting Group 8A-13 reviewed all the incoming liaison statements including the following documents:R8A/40, Feasibility of Sharing Between the Inter-Satellite Service (ISS) and the Mobile Service (MS) in the Band

66-71 GHz (USA), notes that no systems are registered in this band. However due to the effect of oxygenabsorption MS and ISS sharing should be possible.

R8A/42, Liaison Statement to WPs 8A, 8C, 8D and 9D (WP 4A), includes draft new Recommendation,Requirements and Suitable Bands for Operation of the Inter-satellite Service within the Range 50.2 - 71 GHz. Italso includes an assessment of potential allocation of the Inter-Satellite Service in the 66 - 71 GHz band.8A/TEMP/17 is the response which supports these documents.

R8A/47, Frequency Sharing Study Between Non-GSO MSS Earth-to-Space Links and the Land Mobile Service inthe 148-150.05 MHz (Japan), indicates that the Interference Probability may be significant and that further studyis needed.

R8A/50, Liaison Statement to Working Parties 4A, 9D, 8A (WP 7C), includes draft new Recommendation,Sharing in the 8025 - 8400 MHz Band Between the Earth Exploration-Satellite Service (Space-to-Earth) and theFixed, Fixed-Satellite, Mobile and Meteorological-.Satellite Services in Reg. 1, 2, 3. This draftRecommendation recognizes that frequency sharing is possible and provides an analysis of interference betweenthe different satellite systems and mobile services.

R8A/51, Liaison Statement to Study Group (SG 7) - Sharing Aspects between the Fixed and the Mobile Servicesand the Meteorological Satellite Service in the band 7,750 - 7,900 MHz. A reallocation of the Meteorological-.Satellite Services from the band 7,450 - 7,550 MHz to the band 7,750 -7,900 MHz is very desirable due to themutually difficult sharing situation with governmental fixed-satellite service in the former band.

R8A/52, Liaison Statement to Study Groups 8 and 9 (WP 7C), includes draft new Recommendation, Feasibility ofSharing between the Earth Exploration-Satellite Service (Space to Earth) and the Inter-Satellite, Fixed and MobileServices in the Band 25.5 - 27.0 GHz. Also included is an analysis of the separation distances between ESS earthstations and fixed service stations around 26 GHz.

R8A/53, Liaison Statement to WP 8A (WP 7C), includes draft new Recommendation Feasibility of SharingBetween Active Spaceborne Sensors and Other Services in the Vicinity of 410-470 MHz. WP 7C believes thatsynthetic aperture radars and amateur and amateur satellite services (primary in Region 1 and secondary in Region2 and 3) should be able to coexist in the band 430-440 MHz and that further study is necessary to determinerequirements and necessary measures for coexistence.

R8A/54, Liaison Statement from Study Group 7 to Study Groups 4, 8 and 9 (SG 7). In the early 21st century,space research bands 37.5 - 38.0 GHz (moon to Earth) and 40 - 40.5 GHz (Earth to moon) are expected to be usedfor high speed data. The document attached to the liaison provides preliminary return link characteristics of onesuch space research system for the purpose of initiating sharing studies in the subject bands. 8A/TEMP/18 isthe liaison response which indicates that no sharing problems with mobile services are foreseen.

R8A/55, Liaison Statement from the Secretariat distributes draft new Recommendation, Feasibility of Sharingbetween Spaceborn Cloud Radars and Other Services in the Range of 92 - 95 GHz. Spaceborn cloud radars can



determine the vertical profile of clouds and their global distribution to analyze the earth’s radiation budget andthereby predictions of global warming. It recommends that these systems not share common frequency bands.

Output documents from Drafting Group 8A-13 include:8A/TEMP/013 , Liaison Statement to Working Party 9B - Identification of Frequency Bands Above 30 GHz for

Use by the Fixed Service. There is no objection to realignment of the allocation of bands above 30 GHz providedthat equivalent spectrum is maintained for land mobile, as current land mobile use in these bands is light but isexpected to increase.

8A/TEMP/016 , Liaison Statement to Working Party 4A - draft Recommendation, Feasibility of Sharing Betweenthe Inter-Satellite Service and the Mobile Service in the Band 66 - 71 GHz. 8A/TEMP/016 provides WP 8Aapproval of the draft Recommendation.

DRAFTING GROUP 8A-14,DISPATCH TRAFFIC

The meeting report is 8A/TEMP/37 . The chair is V. Rawat, Canada. The Question under study is Question 37.See also the Drafting Group 8A-9 report, above.

This Drafting Group considered two documents on spectrum efficient digital land mobile systems dispatch traffic:

R8A/67 , Modification to Draft Recommendation ITU-R M.[8A/XB] Spectrum Efficient Digital Land MobileSystems for Dispatch Traffic (Question ITU-R 37/8) (LM Ericsson). It proposes to add the Enhanced DigitalAccess Communications System (EDACS) to draft Recommendation ITU-R M.[8A/XB] Spectrum EfficientDigital Land Mobile Systems for Dispatch Traffic.

R8A/70 , Texts Referred Back to WP 8A from SG 8 (Documents 8/7 and 8/36) (pp. 49 - 68) - France.

The following specific points were made during the discussion of R8A/67 (LM Ericsson):

• The document has been submitted as a delayed contribution and hence sufficient time is not available for technicalevaluation.

• The systems described in the current draft Recommendation have been discussed extensively from a technicalviewpoint over a period of two years. The input documents describing these systems were submitted byadministrations, and were the subject of evaluation by national and/or regional standardization bodies (e.g., ETSI,TIA).

• The EDACS Aegis system described in R8A/67 does not fall in the same class as the other systems in the draftRecommendation, particularly in terms of spectral efficiency.

• Evaluation of the EDACS system has not been completed through national/regional standardization bodies which,while not a requirement for inclusion within ITU-R Recommendations, confirms that the standard has gonethrough an appropriately detailed technical evaluation. This was one of the factors used during the developmentof the draft new Recommendation.

• R8A/67 was submitted by a manufacturer (Sector Member) and not by an Administration (Member State) andthus did not undergo the national approval process normally used in the situation.

• EDACS does not comply with Section 2.2 of ITU-R Code of Practice concerning Intellectual Property Rights(IPR).

The representative from LM Ericsson responded:

• EDACS system meets the objectives of the draft Recommendation and ITU-R Question 37/8 which relates to thedraft new Recommendation.

• There are 300 systems installed internationally, which indicates the maturity of system development.

• EDACS has established a users’ group which, among other things, develops user requirements.

• EDACS has been in the TIA process for about a year.

• Ericsson will comply with Section 2.2 of ITU-R Code of Practice concerning IPR.

A number of options were considered with regard to inclusion of EDACS in the draft new Recommendation and thefollowing two options were pursued in detail:



1) Conclude consideration of R8A/67 at this time, i.e., R8A/67 should not be considered any further.

2) Make R8A/67 a working document as an input from Ericsson (i.e., without making it a TEMP document) forfurther technical evaluation, possibly by correspondence and prior to the June 1997 Study Group 8 meeting.

There was general preference for the first option, noting that the second option is nothing more than a reference tothe consideration of R8A/67 in the Chairman’s Report of WP 8A.

R8A/70 from France deals with the TETRAPOL system. The following points were noted:

• This document was referred back from Study Group 8 to Working Party 8A for its consideration for inclusion inthe draft new Recommendation.

• France submitted this document to an earlier meeting of WP 8A (November 1995) where no agreement wasreached to include it in the draft new Recommendation.

• There were questions concerning the status of the TETRAPOL system within the ETSI standardization process;France confirmed that the TETRAPOL forum had recently withdrawn its request from ETSI, however, it plans toreapply to ETSI. The Delegate from France agreed that Section 1.5 requires updating to reflect this recentinformation.

• The delegate from Italy expressed concern that the details of this system are not publicly available and can only beobtained from the TETRAPOL forum which is a private association and only its members have access to thedocumentation. Further, it was noted that no statement has been submitted from the TETRAPOL forum to ITU-R which shows compliance with Sections 2.1 or 2.2 of the ITU-R Code of Practice. France noted that it is statedin their document that they will comply with the ITU-R policy and a statement to that effect can be submittedvery soon. However, the delegate from Italy clarified that as per Sections 2.1 and 2.2 of the ITU-R Code ofPractice, the statement is required from the patent holder and not from the administration.

The following options were considered:

1) Include TETRAPOL system in an annex of the draft new Recommendation, subject to resolution of a number oftechnical and other issues prior to the next ITU-R SG 8 meeting in June 1997. The required work to resolve theoutstanding issues could be done through correspondence so as to obtain approval for inclusion in the draft newRecommendation at the June meeting. This option was acceptable to France, but not to other administrations(UK, Italy) who had expressed concerns.

2) Include the document from France as a working document (i.e., a TEMP document) in the Chairman’s Report ofWP 8A with a list of outstanding issues which could be addressed in the interim period prior to the June 1997meeting. This option was not acceptable to France. France noted that in view of the lack of support at the recentSG 8 meeting and this meeting of WP 8A, it intends to pursue the matter at the next RadiocommunicationAssembly.

The Chair suggested further consideration of the proposed options for both documents at a second meeting of DG8A- 14 so as to allow additional time, however, the participants preferred to close the discussion at this meeting.

DRAFTING GROUP 8A-15,STRUCTURE OF STUDY GROUP 8

The meeting report is 8A/TEMP/52 . The chair is S. Towaij, Canada.

Study Group 8 at its last meeting on 27 October 1996, established an ad-hoc Group to study the structure of StudyGroup 8. The mandate of this group is to review the organization of Study Group 8 in light of current and futuredevelopment in the services within its mandate. As part of the process, Study Group 8 requested from all itsWorking Parties and Task Groups to provide their views on this issue and to input their comments andRecommendations to the ad-hoc Group. 8A/TEMP/52 provides the recommendations of DG 8A-15.

In its deliberations, Working Party 8A considered that the present work could be classified into three categories:

• Wireless access which includes: cellular systems, cordless phone and cordless telecommunication systems,wireless access local loop, FPLMTS, etc. Wireless access is defined as user radio access to the switched networks(PSTN, ISDN, etc.). Study on FPLMTS is presently carried out within TG 8/1. This work is anticipated to becompleted by the end of 1999 when the detailed radio interface Recommendations are completed;



• Other land mobile systems which include dispatch systems, paging systems, RLAN, TICS, ADL, etc.;

• Amateur and amateur satellite.

Study Group 8 discussed a number of structuring scenarios to meet the set-up objectives and considered the followingoptions the most suitable for the work of Working Group 8A:

• All wireless access activities should be carried out within Study Group 8;

• All terrestrial wireless access activities should be carried out within Working Party 8A;

• All satellite wireless access activities should be carried out within WP 8D where the satellite expertise is found,and joint Working Groups between the two Working Parties can facilitate the study of issues of concern to thetwo groups;

• Creation of second layer Sub-Working Parties within a Working Party could result in unnecessary processingdelay and could lead to waste of efforts. The present single task Drafting Group approach is very effective andshould be continued;

• The establishment of correspondence groups to continue the work on high priority issues between meetings isvery effective and should be encouraged;

• Electronic method of communication should be used as the preferred method of work within the correspondencegroups.

Working Party 8A has considered the present structure of Study Group 8 and the following comments andrecommendations are provided:

• All mobile satellite work including satellite wireless access should be maintained within the present WorkingParty 8D;

• Due to the interdependency of the services within the maritime, aeronautical and radiodetermination, it is proposedthat Working Parties 8B and 8C be combined into one Working Party. This could eliminate the need for liaisonbetween these services and could potentially enhance the speed in carrying out the work within these services;

• All terrestrial wireless access work should be carried out within Working Party 8A;

• Study Group 8 is encouraged to set up joint activities with other Study Groups on matters concerning thosegroups (e.g., joint Working Groups, joint Rapporteur Groups, Rapporteur Groups, etc.).

PARTIAL REPORT OF TR-41.6, WIRELESS USER PREMISES EQUIPMENTSYSTEMS, SEPTEMBER 9 – 13, 1996, OTTAWA, ONTARIO

PWT-E, SP-3614

P. Murray (Ericsson, editor of SP-3614) reported that TIA received 12 ballot responses from companies on SP-3614,Personal Wireless Telecommunications - Enhanced Interoperability Standard (PWT-E). There were 10 affirmativeresponses with no comments and two affirmative responses with comments. He questioned why TIA had notprovided copies of the ballot responses directly to TR-41.6.

W. Cruz (Lucent) distributed copies of Lucent’s SP-3614 negative ballot response (TR-41.6/96-09-30), whichcontains technical comments. P. Murray (Ericsson), the editor of SP-3614, said that the ballot response fromLucent Technologies was submitted after the ballot due date, which was July 29, 1996, and should not be counted asa valid ballot according to procedure. He stated that the technical comments that accompanied the Lucent ballotshould be addressed by TR-41.6 as a technical contribution but not as ballot comments. W. Cruz explained that hediscussed this matter with S. Azhar, the TIA Standards Secretariat, and she indicated that in this instance it would beproper and acceptable for him to submit the ballot at the September 12, 1996 meeting. She indicated that this wouldbe acceptable since he, the Lucent voting representative and acting Chair of TR-41.6, did not receive the ballot fromTIA during the original mailing. W. Cruz added that S. Hoyler (TIA) checked TIA records; the ballot had beenmailed to C. Berestecky of Lucent Technologies and chair of TR-41, instead of to W. Cruz, the Lucent representativeof TR-41.6. P. Murray maintained that extending the deadline for submitting the ballot beyond the date shown onthe ballot was not proper procedure and that the extension was not valid. He added that the original ballot wasmailed to Lucent Technologies as well as all the other companies, and that failure inside a company to redirectdocuments was not a committee concern. He received ballot responses from almost all the companies.

The Chair of TR-41 and the TIA representative, S. Hoyler, were asked for clarification of the rules on ballots beingreceived after the expiration of the ballot period. The information given was that the committee could review thecomments attached to the ballot and may consider the no vote of the ballot if the majority choose to do so. TR-41.6discussed whether to consider the Lucent ballot.

M. Hosford (Lucent Technologies) encouraged the TR-41.6 attendees to vote to consider the Lucent ballot as a validballot response because the technical comments in the Lucent ballot raise genuine issues of radio interference thatneeds to be addressed in the PWT-E standard. The CEPT RM10/SE7 Joint Project Team (JPT) performed ananalysis of interference problems that exist between the DECT and DCS 1800 systems. Since PWT-E standard isbased on the DECT standard, the PWT-E system would have interference problems with PCS systems in adjacentbands. The out-of band emissions of the PWT-E base stations transmitting in the 1930-1990 band would causeinterference to Base Stations of Licensed PCs Frequency Division Duplex (FDD) technologies operating in an adja-cent band. The out-of-band emissions of the PWT-E base stations transmitting in the 1850-1910 MHz band wouldcause interference to Portables of Licensed PCS FDD technologies operating in an adjacent band. M. Hosford thendistributed copies of PN-3777, Licensed PCS-PCS Interference, to become a TSB. The TSB provides specificationsfor spectrum coordination rules at geographic and spectrum band edges and is designed to facilitate the reduction ofinterference from adjacent band and co-band systems. P. Murray indicated that the quoted document with reference toDECT and DCS 1800 was an old document and that more studies had been carried out since that study was releasedwhich showed that interference between both technologies was around 1%. He also indicated that the interferenceexisted between all the other PCS technologies and none of them had been stopped in the balloting process becauseof the potential. P. Murray also brought up the interference potential to unlicensed by the licensed technologies.

M. Hosford noted that TR-46 is addressing interference issues between licensed PCS technologies operating inadjacent bands in PN-3777; TR-41.6 needs to address the same PCS-PCS Interference issues (PPI) in the PWT-Estandard since PWT-E operates in the licensed PCS band. P. Weismantel (NEC) was concerned about theinterference the unlicensed PCS technologies would receive from the Out-Of-Band Emissions of Licensed PCStechnologies Base Stations transmitting in the A-band. N. King (Siemens Rolm) agreed that TR-41.6 needs toaddress interference issues between PWT-E and other Licensed PCS technologies operating in neighboring bands,however he felt it did not need to be addressed in the standard. He noted that none of the previously approved Li-censed PCS standards address PPI issues as part of the standard, although they all have the identical problem;therefore it should not be necessary for the PWT-E standard to address PPI within the standard. In addition, N. Kingsaid that the administrative overhead which would result from holding back the standard would delay the technicaleffort required to handle the PPI issue, because the same people required to handle the PPI issue would be spendingtime addressing the re-balloting issue. P. Murray suggested that TR-41.6 can provide input to PN-3777 to addressinterference between PWT-E and the other licensed PCS technologies. P. Murray reiterated that TR-41.6 should



address the technical comments in the Lucent ballot response; however, TR-41.6 should not consider the Lucentballot because it was submitted after the deadline.

After more discussion on this issue, there was general agreement for TR-41.6 to provide input to TR-46 to addressPWT-E interference with other Licensed PCS technologies in PN-3777. M. Hosford authored the followingstatement, which the TR-41.6 attendees agreed to:

TR-41.6 acknowledges the Lucent ballot and comment on PCS to PCS Interference concerns. While thecommittee does not feel that consideration of this vote will further the development of SP-3614 at this time, TR-41.6 does feel that the concerns outlined in this ballot comment are very relevant to addressing quality of servicefor all PCS systems. TR-41.6 will work closely with TR-46.2.1 to develop the TSB 3777, PCS to PCSInterference document as uniform, equitable standard that all PCS systems may use to insure the highest qualityof service. TR-41.6 will liaison a work plan and document outline to TR-46.2.1 so that the concerns of TR-41.6may be incorporated in TSB 3777.

PWT-E (SP-3614) was approved for submission to ANSI’s Technical Subcommittee for ANSI approval as astandard.

M. Hosford urged TR-41.6 to provide input to TR-46 on PN-3777 as soon as possible because TR-46 is freezing thetext for the document on November 20, 1997. P. Murray (Ericsson) volunteered to be the liaison between TR-41.6and TR-46. He will present a liaison letter to TR-46 requesting that the date for freezing the text for PN-3777 bemoved to allow sufficient time for TR-41.6 to provide input to the document. The next TR-46 meeting isSeptember 30 - October 4, 1996 in San Francisco. TR-41.6 agreed to have an interim meeting, via conference call,on October 15, 1996 to discuss the various contributions on PPI and develop input to PN-3777. TR-41.6 alsoagreed to have an emergency interim meeting, via conference call, on September 26, 1996 to discuss the variouscontributions on PPI and develop input to PN-3777. (Editor’s note: TR-46.2.1, in response to the liaison fromTR-41 received at their Sept.-Oct. meeting, noted that the intent was that PN-3777 would be technically accurate andsufficiently complete to initiate an interference analysis for spectrum coordination prior to any final decision to freezethe document. TR-46.2.1 determined to consider unlicensed technologies at a later time, since their present scopeand charter do not include unlicensed technologies. See the TR-46.2.1 report in CSR-R 7.6, Oct. 1996.)

REPORT OF TR-45.2, INTER-SYSTEM OPERATIONS STANDARDSOCTOBER 7 – 11, 1996, BURLINGTON, VT

TR-45.2/96.10.07.01 (C.J. Blum, TR-45.2 Chair, Lucent) is the agenda. Included with the agenda is thefollowing correspondence:• Outgoing correspondence to IFAST (International Forum on AMPS Standards Technology) providing PN-3173

(International Implementation of Cellular Radiotelephone Systems Compliant with ANSI/EIA/TIA-553) for theirreview. When approved, after ballot, PN-3173 will be a revision of TSB-29. TSB-29 contains importantinformation related to the international application of AMPS-compatible networks.

• Incoming correspondence from McCaw de Colombia. System Identification numbers (SIDs) 05732, 05734, and05772 were currently being used by Celumovil and were reserved for the US PCS providers. They requested thatthe numbers be changed to be reserved for Celumovil. TR-45.2.6 was directed to resolve their assignment (i.e.,put into the exception table of TSB-29).

• Incoming correspondence from D.M. Brodman (Cibernet) proposes that the SID range reserved for US PCScarriers as published in TSB-29 be updated to reflect the Celumovil SIDs. This was also remanded to TR-45.2.6.

• Incoming correspondence from T1S1 providing comments from discussions regarding ISUP (ISDN User Part)support for wireless provisioning of E911. It appears that a misunderstanding occurred. More information wasto be provided to T1S1. It was remanded to the E-911 ad hoc group.

• Incoming correspondence from T1S1 proposing cooperation on Wireless Intelligent Networking (WIN) work. Itwas directed to the TR-45.2.2 WIN Task Group.

TR-45.2/96.10.07.05 , T1/TIA Joint Standards Document Process, is the output of meetings that were held toconsider both process issues and work allocation within T1 and TIA and to draft a detailed implementation plan forthe Joint Standards Document (JSD) proposal. The development of a JSD is performed totally within oneorganization (TIA or T1) and ballots go to both organizations. It was noted that information on the JSD processshould be included in the TIA Engineering Manual.

TR-45.2/96.10.07.07 (NSA and GTE) provides inputs to user requirements for both commercial and federalusers of the Cellular Net Broadcast Service (NBS). The NBS provides push-to-talk multicast dispatch-typecommunications services for taxi, dispatch, law enforcement, construction and public safety over commercial digitalwireless systems. It was recommended that this contribution be forwarded to CTIA. TR-45.2/96.10.11.02 isthe resultant outgoing correspondence to E. Hall (CTIA). It provides a copy of TR-45.2/96.10.07.07 and seeksassistance in ascertaining the level of interest and priority of this service with respect to other work items underconsideration by CTIA for standardization in 1997.

TR-45.2/96.10.07.04 is a TIA press release clarifying a New York Times article (September 20, 1996) onElectronic Surveillance. The article had suggested that the FBI interpretation of the requirements for the LAES workhad been rejected by the wireless communications industry. The TIA press release notes the ongoing process todevelop industry (including the FBI) consensus. It was provided for information.

WORK PLAN

TR-45.2/96.10.07.03© (C. Blum, TR-45.2 Chair, Lucent) provides the 1996 work plan based upon modificationsapproved at the September meeting. The editorial review of SP-3588 (Cellular Radio TelecommunicationsIntersystem Operations) will occur at the November and December TR-45.2 meetings. Approval for publication wasplanned for January 1997.

The editorial review of PN-3293 (IS-124-A, Cellular Radio Telecommunications Intersystem Non-Signaling DataCommunications Standard) was scheduled for the first week of November and during the November TR-45.2meeting. Approval for publication was still scheduled for November 1996.

The schedule for PN-3580 (Intersystem Operations Support for the Lawfully Authorized Electronic Surveillance(Intercept) Capability) was extended. The document will be frozen and V&V will begin in December. Approval forballot was planned for January 1997.

The proposed schedule for IS-41-D (next revision of ANSI-689) was to be ready for ballot by December 1997.

There were no changes to any of the other projects.



MANAGING AND TEXT PROCESSING FOR IS-41

There was much discussion on the managing and text processing for IS-41. The following plan was proposed andgenerally agreed to by TR-45.2. This plan will be forwarded to TR-45 and its Subcommittees for review andcomments.

Features/Services will be packaged and published as stand-alone documents containing the Stage 1, 2, and 3descriptions. The work on OTA (Over-the-Air Activation), DCCH (Digital Control Channel) Features, CDMAFeatures, and Data Services, which are presently separate projects, will be published as stand-alone documents.Stage 3 definition of operations and parameters for these services will be included in the next revision of IS-41 (i.e.,next revision of ANSI-689).

Basic IS-41 core enhancements, such as IMSI (International Mobile Station Identity) and TSB-76 (PCS Multi-Band),will be incorporated into the next revision of IS-41 (i.e., next revision of ANSI-689).

It was suggested that WIN be developed as a stand-alone document. However, there were concerns that this workaffects the IS-41 core and should be incorporated into IS-41. The WIN Task Group was requested to review thisissue and provide a recommendation.

All current projects are to proceed on schedule; the text processing format will be Word 5.1.

All projects including ANSI-689 will be converted to Framemaker by end of year 1997. It was agreed that in orderto achieve this goal, the first step was to develop a single (common) style sheet, convert all files to this single style,and then convert all files to Framemaker. T. Jacobson (Lucent) and T. Watts (Southwestern Bell) accepted anassignment to develop this common style sheet.

G. Pavon (Ericsson) offered to convert PN-3579 (DCCH) to Framemaker, and T. Watts offered to convert ANSI-689to Framemaker.

Additional contributions affecting the reorganization of IS-41 (i.e., TR-45.2 .3 /96 .10.09.08 below) are stillunder review and deliberation by TR-45.2.

LIAISON REPORTS

T1S1Ballot comments for Call Completion to Ported Numbers were reviewed. There was one outstanding No vote toresolve.

T1P1Correspondence will be forwarded to TR-45.2 regarding the default ballot of PACA-E (Priority Access and ChannelAssignment - Enhanced ). T1P1 suggests convening a small group to discuss the process for evaluation of radiotechnologies for FPLMTS (Future Public Land Mobile Telephone Systems).

TR-45 NMAG Network Management Ad hoc GroupThe model for Stage 2 and Stage 3 development will be distributed to the TR-45 subcommittees.

TR-45 International Standards DevelopmentContributions on digital vocoder technologies developed in TR-45.3 and TR-45.5 had been approved for submissionto ITU-R Working Party (WP) 8A.

Industry Carriers Compatibility Forum (ICCF)The Feature Code Guidelines will include assignments for the wireless industry.

NENA/APCOTen and 20 digit ANI (Automatic Number Identification) will be supported in Feature Group D and ISUP. NENA(National Emergency Number Association) had created two sub-task groups, one for wireless and one for wireline.The wireless group will accommodate satellite. The wireline group will address non-call associated signaling andsignaling between the Selective Router and the PSAP (Public Safety Answering Point). There were some seriousimplications to 911 and trunking issues due to Number Portability. NENA/APCO (Associated Public SafetyCommunications Officers, Inc.) is reviewing use of 911 as NXX code and the ability to use this format for aroutable number. There was discussion of using 311 for non-emergency calls.

AGNITR-45.2/96.10.07.06© (T. Jacobson, Lucent) provides a summary of the AGNI (Advisory Group for NetworkIssues) meeting held on September 13, 1996. It was provided for information. Ameritech has withdrawn from



CTIA. There was increased use of ISUP for call set-up and to support CNAP (Calling Name Presentation) delivery.A new sub-task group was formed to address Data Message Handler (IS-124 transport issues, volume of traffic, etc.).The AGNI does not consider 1-800 calls (e.g., GM OnStar, Ford RESCU, SOS Company) as “emergency calls”.The CTIA has issued some guidance to standardize call handling procedures in general, e.g., 1+ dialing.

TR-45.2 AND AHAG JOINT SESSION

The purpose of this meeting was to discuss the process for development of standards for IS-41 and IS-124 (CellularRadio Telecommunications Intersystem Non-Signaling Data Communications) Message Security.

TR-45.2/96.10.07.08© (F. Quick, Qualcomm) provides suggestions for the joint AHAG/TR-45.2 project onIntersystem Messaging Security (IMS) similar to the way authentication Annex A was developed.

TR-45.2/96.10.09.01 (C. Blum, TR-45.2 Chair, Lucent) addresses Intersystem Message Security.

These contributions both indicated the need to form an ad hoc group to address this work. There was discussion ofthe priority of this work in light of the current and projected work plans of both TR-45.2 and the AHAG. There wasalso concern related to the resources to work on IMS. An ad hoc group was then formed under TR-45.2 to addressthis work. J. Crollick (GTE-TSI) was appointed as Chair. The first meeting of the group was scheduled forNovember 18-20 in Dallas, Texas. The first objective of the group is to identify the scope of the project, to define awork plan, and to determine resources required to address this work.

Issues related to the User Identity Module (UIM)/SMART Card were then discussed. It was noted that there weresome security issues and some networking issues related to UIM/SMART card. It was decided that TR-45.2 and theAHAG will each respond separately to TR-45 on these issues. TR-45.2 .1 /96 .10.09.02 (ANSI) is T1P1.2/96-105R3 draft “Requirements for a User Identity Module (UIM) for Personal Communications Services.” It wasprovided for information and discussion. TR-45/96-05.29.27 is the Stage 1 Description (V1.1) of Smart Card.It proposes functionality including:• Privacy key management and authentication• Personalized feature subscription record• Non-telephony apps., e.g., credit card, electronic coin purse, loyalty program(s)• Remote management of data/fax/voice applications

INTERIM TR-45.2 PLENARY FOR LAES

The purpose of this plenary session was to address any issues reported by the LAES (Lawfully Authorized ElectronicSurveillance) Ad Hoc Group.

The LAES Ad Hoc Group Chair addressed the following issues which require action by the TR-45.2 plenary.

It was recommended that the Location parameter be added to the Origination Attempt, Answer, and Packet Envelopemessages. TR-45.2 reached consensus on this issue, noting one opposition by Synacom. It was noted that adefinition of “Location” was needed.

A motion was made by K. Carlson (Synacom, seconded by J. Crollick, GTE-TSI) to “Add the Location parameter tothe Release message.” A vote returned 1 in favor, 10 opposed, and 7 abstains. The motion failed.

A motion was made by K. Carlson (Synacom, seconded by J. Crollick, GTE-TSI) to “Add a Location Updatemessage as proposed by TILU (Telecommunications Industry Liaison Unit, FBI) in TR-45.2AdHocElcSurv/96.09.24.06.” This message would report location as mobiles are handed off between cells. Avote returned 2 in favor, 12 opposed, and 6 abstains. The motion failed.

A motion was made by K. Carlson to “Provide a message in PN-3580 when the switch is informed of Voice Maildeposit.” There was no second to the motion, therefore no further action was taken.

A motion was made by K. Carlson and seconded by T. Richter (BellSouth) to “Accept the message concept of PartyHold and Party Join in PN-3580.” After some discussion, the motion was tabled and will be carried forward to thenext meeting.

It was recommended to accept the values agreed to by the Ad Hoc Group for call identifying and call contentinformation in the Notification Information Indicator message. There were no objections to this recommendation,and it was accepted by TR-45.2.



It was agreed to forward issues related to the Surveillance Status message, the Feature Status message, and the PacketEnvelope message to the next CTIA Legal Summit.

TR-45.2 accepted the Ad Hoc Group’s recommendation for a revision to the LAES work plan. With this revision,V&V on PN-3580 (LAES) will begin in December; the document will be ready for ballot in January 1997.

It was recommended that Sections 4.7 and 4.8 of PN-3580 be placed in an informative Annex (B) of PN-3580 as perRevision 6. There were no objections to this recommendation, and it was accepted by TR-45.2.

It was recommended that Sections 4.6 and 5.8 of PN-3580 be placed in an informative Annex (C) of PN-3580 withthe exception of Sections 4.6.2 and 5.8.3 (which will be deleted from PN-3580). There were no objections to thisrecommendation, and it was accepted by TR-45.2.

It was recommended that Annexes A and D in PN-3580 Revision 6 (as per TR-45.2AHLAES/96.10.10.06) beaccepted as baseline text. There were no objections to this recommendation, and the text was adopted as baseline.

It was recommended that PN-3580 be prepared as an ANSI standard (per TR-45.2AHLAES/96.10. 10.07). There wasdiscussion related to maintaining the “sensitivity” of the document and the impact of this on publishing thedocument as an ANSI standard. The TR-45.2 Chair will take this as an action item to review with TIA. This issuewas put on hold until the next meeting.

It was recommended to accept TR-45.2AHLAES/ 96.10.10.14 (PN-3580 Revision 6) as baseline text with theexception of the Packet Envelope Message Text and to accept the text for this message as described in Revision 5.There were no objections; TR-45.2 accepted the recommended text as baseline.

TR-45.2 then developed the following list of items/issues to forward to the next CTIA/TILU Legal Summit onOctober 31, 1996:• Location Update and Location parameter in the Release Message• Voice Mail Waiting Notification• Party Hold/Party Join• Notification Message• Feature Status Message• Packet Envelope (on pen registers and Trap/Trace orders)• Surveillance Status Message• Jurisdiction, what actions and areas covered by order, etc.• Definitions for call identifying information, call content, publicly available, reasonably achievable, significant

upgrade• Delivery Format (Uniform protocol for delivery?)

AD HOC EMERGENCY SERVICES

In summary, work on PN-3581 (Emergency Services) is proceeding. Additional Stage 3 work was expected at thenext meeting, but PN-3581 is a stable document. There were no changes to the work plan. It was recommendedthat PN-3581 be issued as a TSB since it was making modifications to five different standards. A new projectrequest was anticipated in December to begin the work on Path C.

TR-45.2.AHES/96.10.10.02© is PN-3581, Emergency Services, proposed baseline text.

TR-45.2.AHES/96.09.19.03© (D. Hose, SignalSoft and E. Sorensen, SCC Communications) comments on thefirst draft revision of PN-3581 and proposes enhancements to the existing PN-3581 so that all PSAPs (Public SafetyAnswering Points), including the majority of existing PSAPs that utilize CAMA (Centralized Automatic MessageAccounting) trunking, can receive benefit from all Path B capabilities. TR-45.2.AHES/96.10.10.03© (T. Jacobson,Lucent) points out significant problems from a WIN perspective with the Stage 2 proposals in TR-45.2.AHES/96.09.19.03© and recommends that this should not be incorporated in PN-3581. It also notes thatalternative mechanisms can be used to support existing PSAP equipment that are compatible with the existing PN-3581 recommendations .

TR-45.2.AHES/96.10.10.04© (S. Hayes, Ericsson) proposes that PN-3581 be balloted as a TSB.

TR-45.2.AHES/96.10.10.05© (A. Maupin, Ericsson) contains the Stage 3 proposal for Location Number retrievalfollowing an inter-MSC (Mobile Switching Center) handoff.



TR-45.2.AHES/96.10.10.06© (D. Hose, SignalSoft and E. Sorensen, SCC Communications) comments on thefirst draft revision of PN-3581 and proposes specific enhancements to the existing IS-41 Origination Request(ORREQ) message to provide call control information from the VLR (Visitor Location Register) to the W911-SCP(Service Control Point) to support MS location for at least Path B and to address special roaming issues. It alsoidentifies provisioning interfaces across the wireless systems and the wireline 911 systems, and suggests an approachfor handling these.

TR-45.2.1 STAGE I DEVELOPMENT

A new project to begin work on SMS (Short Message Services) Broadcast was discussed. A PN request will beprovided at the next meeting.

TR-45.2.2 STAGE 2 DEVELOPMENT

OTA, DCCH, CDMA, Data Services, and ISLP (Intersystem Link Protocol) are in V&V. Work on modificationsto the TR-45 NRM (Network Reference Model) is proceeding.

TR-45.2.2/96.10.07.03© (C. Blum, TR-45.2.2 Chair, Lucent) is PN-3769, IS-41-C Enhancements for OTASP(Over the Air Service Provisioning), baseline text Revision 0.7. It was approved as modified.

TR-45.2.2/96.10.07.04© (G. Pavon and M. Corriveau, Ericsson) provides comments on the currently proposedstage 2 descriptions for the new IS-41 Parameter Directive and Parameter Request messages. The process was notconsidered real-time or used for an active call handoff. The contribution was referred to NMAG for furtherconsideration. (See TR-45.2/96.10.11.03 , outgoing correspondence to NMAG from TR-45.2, below.)

TR-45.2.2/96.10.07.05© (Qualcomm) discusses the benefits of locating the Inter-Working Function (IWF)functionality on the BS (Base Station) side of the A-Interface.

TR-45.2 .2 /96 .10.07.06 (D. Crowe, Alcatel) proposes a new IS-41 assumption that indicates that while theMSC may contain an incomplete database, IS-41 is not optimized for systems where the MSC has no capability forretaining information about registered mobiles. It was accepted as modified and forwarded to IS-41 Editor.

TR-45.2.2/96.10.07.07© (T. Jacobson, Lucent) proposes the addition of the Service Control Point (SCP), theIntelligent Peripheral (IP), and the Service Node (SN) network entities and their associated reference points to the IS-41-D Network Reference Model (NRM).

TR-45.2.2/96.10.07.08© (S.S. Chander, Lucent) defines new Stage-3 parameters for support of the CDMABroadcast SMS (Short Message Services) teleservice. These new parameters impact only the SMDPP INVOKEoperations.

TR-45.2.2/96.10.07.10© (S. Mizikovsky and B. Ayabe, Lucent) highlights some inconsistencies in Broadcast SMSlayering in IS-637 (Short Message Services for Wide Band Spread Spectrum Cellular Systems) and suggestscorrections.

TR-45.2.2/96.10.07.12© (S.S. Chander, Lucent and J. Tang, Ameritech) adds support for Broadcast Short MessageService (SMS-B) in the form of a new teleservice called Broadcast SMS Teleservice (BST). BST utilizes theexisting Short Message Delivery bearer service and associated operations and scenarios with a few new parameters inaddition to ones that have already been defined in the air interface standards.

TR-45.2.2/96.10.07.13© (S.S. Chander, Lucent) provides a Stage 2 scenario whereby the existing SMS operationShortMessageDeliveryPointToPoint (SMDPP) is re-used to provide the intersystem support for CDMA BroadcastSMS defined in IS-637.

TR-45.2.2/96.10.07.09© (S.S. Chander, Lucent) provides Version 2 of the definitions for the support of intersystemCDMA Soft Handoff.

TR-45.2.2/96.10.07.11© (S.S. Chander, Lucent) provides enhancements to Stage 3 operations and parameters (asthey relate to IS-41C) for the support of intersystem CDMA Soft Handoff.

TR-45.2.2/96.10.07.14© (S.S. Chander, Lucent) provides enhancements to Stage 2 operation scenarios for thesupport of intersystem CDMA Soft Handoff.



TR-45.2.2/96.10.07.15© (S.S. Chander, Lucent) proposes two more Stage 3 values for inclusion within theReasonList parameter, originally defined in the Data Services TSB (PN-3770) for TMSI (Temporary Mobile StationIdentity) related causes.

TR-45.2.2/96.10.07.16© (S.S. Chander, Lucent) defines a new Stage 3 parameter calledSMS_DeliveryRequirements for inclusion within the SMDPP INVOKE operations and provides associated changesfor the support of Signaling Message Encryption with SMS message delivery.

TR-45.2.2/96.10.07.17© (C. Ishman, Motorola) contains proposed TR-45.2 recommendations for IS-41-D NetworkReference Model (NRM) enhancements. It supports a single representation of each Mobile Network Entity (MNE)within the NRM and an IWF with a neutral air interface technology and non-circuit mode.

TR-45.2.2/96.10.08.01© (A. Sicher, Ericsson) provides TDMA parameter definition input for the Stage 3 ServiceDescription for Data Services. It was accepted with modifications.

TR-45.2.2/96.10.08.02© (S. Broyles, Qualcomm) proposes V&V changes to PN-3770.3 (Intersystem OperationsSupport for Data Services). It was accepted with modifications and deletions.

TR-45.2.2/96.10.08.03© (S. Broyles, Qualcomm) proposes V&V changes to PN-3770.2.

TR-45.2.2/96.10.08.04© (S. Broyles and J. Tomcik, Qualcomm) proposes V&V changes to PN-3660 (InterSystemLink Protocol [ISLP] for Data Services).

TR-45.2 .2 /96 .10.08.05 (D. Crowe, Alcatel) suggests guidelines for the operational procedures to be followed inthe work developing the TR-45.2 Network Reference Model Focus Group. It suggests that consensus requires morethan 2/3 of those present to be in agreement.

TR-45.2 .2 /96 .10.08.06 (D. Crowe, Alcatel) contains suggestions for modifications to the proposed TR-45NRM. It describes the decision points approved by the NRM Focus Group and those still open for discussion.

TR-45.2.2/96.10.08.07© (R.J. Marks, Lucent) notes that an additional BS and A interface is required when the Linterface reference point is placed between the MSC and the IWF rather than placed between the BS and IWF.

TR-45.2.2.5 CDMA

TR-45.2.2.5/96.10.07.02© (S. Broyles, Qualcomm) proposes additional parameters (CDMAPowerControlinformation and CDMASearchParameters) that are useful in providing real time updates to information used forhandoff operations.

TR-45.2.2.5/96.10.07.03© (T.T. Towle, Lucent) provides text (section 5 Basic Intersystem Handoff Scenarios ) forCDMA soft handoff scenarios from an inter-system perspective.

TR-45.2.3 STAGE 3 (ENCODING & PROCEDURE) DEVELOPMENT

TR-45.2.3/96.10.09.03© (S. Broyles, Qualcomm) proposes additional parameters (CDMAPowerControlinformation and CDMASearchParameters) that are useful in providing real time updates to information used forhandoff operations. It is an update to TR-45.2.2.5/96.10.07.02©.

TR-45.2.3/96.10.09.04© (J. Mohanty, DSC) identifies an inconsistency in TCAP (Transaction CapabilitiesApplication Part) between IS-41.5-C and ANSI T1.114.

TR-45.2.3/96.10.09.05© (J. Mohanty, DSC) recommends some editorial text modification in IS-41.6-C.

TR-45.2 .3 /96 .10.09.06 (P. Reddy and T. Watts, Southwestern Bell) proposes settings of Message WaitNotification flag in HLR (Home Location Register) using a generic SMS_Request message with new teleservice ID,MIN or IMSI, MWI_Count, MWI_type, MWN_flag, sent from Service Node or Voice/Fax Mail systems or anyadjunct network entities. It supplements the approved version of IS-41-C by providing capabilities to supportVoice/FAX/Data messages waiting notification as required by the contributing operators and vendors.

TR-45.2 .3 /96 .10.09.07 (Alcatel, Hughes, and Aldiscon) proposes the addition of a new teleservice for voicemessage notification to support IS-136 (800 MHz TDMA Cellular - Radio Interface - Mobile Station - Base StationCompatibility - Traffic Channels and FSK Control Channel) TDMA digital terminals.

TR-45.2 .3 /96 .10.09.08 (D. Crowe, Alcatel) proposes removing sections from the IS-41 document that areredundant; this would reduce the page count by 565 pages (remove redundant Stage II from sections 2 and 3,



eliminate section 6 procedures but add the few truly procedural aspects to section 5, and remove the GSL descriptionfrom Annex E).

TR-45.2.3/96.10.09.09© (S. Broyles, Qualcomm) proposes PN-3770 baseline text changes in support ofDataPrivacyParameters and CDMASeviceOption parameters.

TR-45.2.4 MESSAGE ACCOUNTING

TR-45.2 .4 /96 .10.08.03 (J. Willse, CRAG) points out what CRAG perceives as needed additions to IS-124(Cellular Radio Telecommunications Intersystem Non-Signaling Data Communications Standard, SP-3816). Theseadditions provide additional identification of the sending and receiving party for the aggregate process to make it morelike the existing settlement between carriers using the CIBER batch operation.

An interim meeting was planned for an editorial review on November 4-6, 1996. It was expected to wrap up detailsrelative to the publishing of IS-124 Revision A at that time.

TR-45.2.6 INTERNATIONAL APPLICATIONS

It was reported that Celumovil only assigned three conflicting SIDs, and an exception was made to allow Celumovilto maintain those assignments per an agreement by D.M. Brodman (Cibernet). This exception will be documentedin TSB-29-B. All other SID assignments by Celumovil will be made from their assigned range.

TR-45.2 .6 /96 .10.09.04 (D. Crowe, Alcatel) addresses problems with PC/SSN (SS7 Point Code/Sub-SystemNumber used to address a point within a national network) embedded in IS-41 messages that pass throughinternational gateways. It recommends alternative ways of identifying systems.

TR-45.2 .6 /96 .10.09.05 (ITU) is the list of Mobile Country or Geographical Area Codes, Complement to ITU-T Recommendation E.212 (March 1, 1996).

TR-45.2 .6 /96 .10.09.06 (D. Crowe, Alcatel) is a proposed liaison report on TR-45.2 subcommittee standardsstatus that are relevant to the work of IFAST.

CLOSING PLENARY

TR-45.2/96.10.11.03 is outgoing correspondence to H. Halliburton (AirTouch), TR-45 NMAG Chair, regardingTR-45.2’s review of contributions recommending the introduction of two new operations, ParameterDirective andParameterRequest, into IS-41. The two operations are sent between neighboring MSCs. Their function is to updaterelevant handoff information in the appropriate databases, which contain information used by border cells during thehandoff process. It requests assistance in determining if this proposed functionality is relevant to IS-41 or toOAM&P (Operations, Administration, Maintenance & Provisioning).

TR-45.2/96.10.11.05 (J. Willse, CRAG) makes eight comments that CRAG considered in reviewing theNMAG baseline text, especially the Accounting Management Section (3.5). The Plenary agreed to forward this tothe NMAG as comments on the Stage 1 description and to note that additional comments are forthcoming.

TR-45.2/96.10.11.06© (B. Daly, AT&T) provides pages necessary to complete the IS-136 portion of the OTASP(Over the Air Service Provisioning) V&V baseline text (PN-3769).

TR-45.2/96.10.11.07 is an FCC Public Notice titled “The North American Numbering Council (NANC)Chairman Announces Organizational Structure and Seeks Working Group and Task Force Participants,” CC DocketNo. 92-237. On October 1, 1996 the NANC held its initial meeting at the FCC and is looking for industry supportin the form of individual contributors.

TR-45.2/96.10.11.08 is proposed outgoing correspondence to E. Hall (CTIA) regarding the Multiple-HLR(Home Location Register) Query project (PN-3528). The project had been on hold for some time, since the Mexicancarriers indicated that it was not the solution they had chosen as their short-term US roaming problem resolution.The CTIA’s opinion is requested. It was approved as modified.

TR-45.2/96.10.11.09 is proposed outgoing correspondence to the IFAST Chair providing a liaison report withthe status of TR-45.2 standards. It was approved as modified.

REPORT OF TR-45.3, DIGITAL CELLULAR STANDARDSSEPTEMBER 17 – 18, 1996, LOS ANGELES, CA

The Chair, P. Nurse (Lucent), requested that the members consider the creation of a new Working Group (WG) toaddress performance issues. Comments indicated that this may create a problem in unnecessarily lengthening themeetings, and the decision was deferred. The Chair also stressed the importance of Stage 1 descriptions and the coreanalog document in the immediate efforts.

CORRESPONDENCE

TR-45.3/96.09.17.03© (P. Nurse, TR-45.3 Chair, Lucent) is incoming correspondence as follows:• From L. Owens (AT&T), TR-45 AHAG Chair, dated July 1, 1996, requesting updated information on all PNs as

they relate to security/privacy. E. Ornelas (NEC) agreed to create a draft response to AHAG for the next meeting.• A. G. Gardner (Ericsson), TR-45 NAG Acting Chair, dated July 3l, 1996, requesting input on PN-2716

(Evolution and Maintenance of the TIA/TR-45 Wireless Network Reference Model) and on whether an InterfaceReference Point labeled “Pi” can be added between the IWF (Inter-Working Function) and PSPDN (PacketSwitched Public Data Network). It was remanded to TR-45.3.6.

TR-45.3/96.09.17.04© (P. Nurse, TR-45.3 Chair, Lucent) contains outgoing correspondence. It includescorrespondence to S. Azhar, TIA Standards Secretariat, recommending PN-3690, TDMA Cellular/PCS - RadioInterface - Minimum Performance Standards for IS-641 Full-Rate Voice Coder, for publication as IS-686.

TR-45 REPORT

The TR-45.3 Chair, P. Nurse (Lucent), provided a verbal report of the last meeting of TR-45 as follows:

A TR (Technical Requirements) leadership meeting was convened on August 27, 1996. The Chairs were remindedthat the Subcommittees are part of TR-45 and could do more to support each others’ efforts.

There was agreement to follow the Stage 1, Stage 2, Stage 3 approach to development of standards.

There was agreement to distribute Stage 1 descriptions to all Subcommittees.

There was agreement within the leadership to exchange new requests for project numbers via email.

There was some discussion, and the following points recorded:• TR-45-3 had, in the past, distributed Stage 1 descriptions which had been ignored for prolonged periods and were

then “mangled” prior to publication.• There was a desire to clarify the role of TR-45.2 in the development of Stage 1 descriptions, particularly with

respect to features or services that could be added with no change to IS-41 (Cellular Radio TelecommunicationsIntersystem Operations). The Chair agreed to raise this issue at the next TR-45 leadership meeting.

• It was reported that TR-45-2 had resolved that IS-53 (Cellular Features Description) would no longer be updatedwith Stage 1 descriptions. Two alternatives were discussed with respect to publishing Stage 1 descriptions: as aninformative annex to the relevant standard or as a separate document. It was proposed that guidelines for writingStage 1 descriptions would be useful, and A. Sacuta (Ericsson) agreed to provide a contribution at the nextmeeting. There was concern that services need to be addressed from an end-to-end perspective. It was agreed toadd an agenda item at the next meeting.

TR-45 created an ad hoc group on Wireless Local Loop (WLL). Members with interest in Wireless Local Loop wereencouraged to attend the meeting of that group.

The Chair reported that he had requested clarification concerning support of TDD (Telecommunications Devices forthe Deaf).

SP-3598 (800 MHz Analog Cellular Systems Mobile Station – Base Station Compatibility) was distributed to theChairs of the Subcommittees and were available to members upon request. The Chair reported that it was hisunderstanding that this copy had been superseded and that the updated copy would be introduced at this meeting.

TR-45.3/96.09.17.05© (P. Nurse, TR-45.3 Chair, Lucent) is a copy of the report (August 12-16, 1996) submittedon behalf of TR-45.3 to TR-45. Table 2 (below) notes the status of each TR-45.3 project.

TR-45.3/96.09.17.06© (P. Nurse, TR-45.3 Chair, Lucent) contains contributions that were remanded from TR-45.The following is a list of these contributions and the actions taken:



• TR-45/96-08-29-03© (D. Lee, National Spectrum Managers Association [NSMA] Working Group 20 Chair,BellSouth), NSMA Technical Data Requirements for PCS System Interoperability Issues. It was remanded toTR-45.3.6.

• TR-45/96-08-28-28©, the 1997 TR-45 meeting schedule. It was agreed to move the TR-45.3 meeting scheduledfor June 1997 to avoid the conflict with TR-45.

• TR-45/96-08-28-33 , correspondence from C. Wallace, TR-46 Chair, to J. Marinho (Lucent), TR-45 Chair,providing the PN-3777 (PCS to PCS Interference) work plan and the August version of PN-3777. TR-46 plansto ballot the outdoor system interference issues between licensed technologies (1850-1910, 1930-1990 MHzbands) by February, 1997 and the indoor system by July, 1997. TR-46.2.1 will continue their review of TSB-10F (Interference Criteria for Microwave Systems) in order to assess its applicability in relation to adjacent bandand co-band interference effects of PCS systems. TR-46 plans on liaisons with TR-14, TR-41, T1P1, NSMAand IEEE 802.11.

TR-45.1 L IAISON REPORT

TR-45.3/96.09.17.07© (D. DeVaney, Astronet) is the TR-45.1 liaison report from the meeting of September 10-12,1996. Table 3, below, notes the status of the TR-45.1 projects.

TR-45.3/96.09.17.10 contains SP-3598 (800 MHz Analog Cellular Systems Mobile Station – Base StationCompatibility, TIA-553-A), dated September 15, 1996.

C. Teising (Lucent) provided the following information. There had been agreement at TR-45 that TR-45.3 and TR-45.5 would have an opportunity to review SP-3598 prior to its next ballot. C. Teising introduced this document asEditor of SP-3598 and at the request of TR-45.1. The contribution provided change bars to highlight the differencesbetween the original ballot version and the version dated September 15, 1996.

The major changes are summarized as follows:• Removal of narrow band analog operation (NAMPS), and of extended protocol• Addition of power-up/power-down registration, and support of location areas• Addition of Alert-with-info, Flash-with-Info, and serial number request

Under active consideration in TR-45.1 was the addition of Abbreviated Alert, disable DTMF

TR-45.2 L IAISON REPORT

T. Richter (BellSouth) reported. TR-45.2 had not met since the last meeting of TR-45.3 and was currently insession. TR-45.2 has:• Completed resolution of ballot comments with respect to SP-3588 (ANSI version of IS-41 to be published as

TIA/EIA 689),• Recommended TSB-76 for publication (Multi-Hyperband Hand-off),• Scheduled a meeting in October to conduct V&V on PN-3579 (DCCH support),• Scheduled to begin V&V of the text to describe support for Over-the-Air Activation in October in parallel with

the next meeting of TR-45.3.

AHAG LIAISON REPORT

S. Willhoff (Nokia) reported. The TR-45 AHAG had met on September 16 and 17, 1996.

AHAG is in receipt of the report of the CTIA Network Security Forum. It was anticipated that the review of thisreport would extend into December 1996.

There were concerns that to undertake a comparative security vulnerability assessment was not within the mandate ofTR-45 and, therefore, was not an active program.

With respect to the questions raised by TR-45.3:• The only documents that contain ITAR (International Traffic in Arms Regulations) controlled information are

“Appendix A of IS-54-B” and “Common Cryptographic Algorithms.” “Interface to Common CryptographicAlgorithms” and Appendix A to the various standards since IS-54-B were considered “sensitive” but contained noITAR controlled information.

• The exportability of systems compliant with IS-136-A (800 MHz TDMA Cellular - Radio Interface - MobileStation - Base Station Compatibility - Traffic Channels and FSK Control Channel) and IS-54-B (TDMA) was tobe added to the agenda of the next meeting with NSA (National Security Agency).

AHAG has information concerning the computational resources required to support Elliptic Curve Cryptography. Itappears not to support the claim that this technology offers performance improvement over the existing technology.



AD HOC GROUP ON IS-641 CONTRIBUTION TO US STUDY GROUP 8A

S. Willhoff (Nokia) reported that the Ad Hoc Group had completed its assignment, and the agreed text had beenforwarded to E. Schimmel, US Study Group 8A Chair, and to C. Blum, TR-45 Ad-Hoc Group on InternationalStandards Development Chair. A copy of the agreed text, Overview of Enhanced Full Rate Codec, was provided inTR-45.3/96.09.17.09. Some minor editorial corrections were agreed upon, and S. Willhoff agreed to forward theamended text to E. Schimmel and C. Blum.

AD HOC GROUP ON ITU LAND MOBILE HANDBOOK

J. McQueen (UWCC) reported that the Ad Hoc Group had completed its assignment. The proposed text, TDMASection of the ITU-R Land Mobile Handbook, is contained in TR-45.3/96. 09.17.08. It was agreed to hold thisitem open to allow members time to review the proposed text.

TDMA PACKET DATA

Since there had been no contributions on this topic for three meetings, it was agreed to terminate this project.

OTHER HIGHLIGHTS

During a review of potential incompatibilities between IS-136 and SP-3598, an error was discovered in thedescription of authentication on the FSK control channel. This error is present in IS-54-B and therefore in TIA/EIA-627. It is to be corrected with this addendum to TIA-627, SP-3827. This was described with proposed text in TR-45.3/96.08.14.05© (Lucent), which was supported for ANSI Industry Ballot. (Editor’s note: Industry ballot for SP-3827 closes December 18, 1996.)

After some discussion, it was agreed that the Chair would respond to T1P1 with respect to PCS-PCS interference asfollows:

We are concerned that uncoordinated development of spurious emission requirements may lead to systems that arenot deployable in close proximity to each other. It is our understanding that cooperative efforts are underway todevelop standards in this area under PN-3777, which has recently involved TIA TR-14, TIA TR-45, TIA TR-46,and the National Spectrum Managers Association. We encourage T1P1 to participate fully in these cooperativeefforts.

We note that your analysis is based upon PN-3386 (J-STD-009), which, for all practical purpose, has beenreplaced by TIA/EIA IS-137-A.

We are also concerned that your correspondence contains no analysis with respect to potential interference betweenbase stations which is also a consideration when determining the feasibility of co-locating different technologies.

TR-45.3.2 DATA SERVICES

A Stage 1 description for Circuit Switched Access to Packet Data Networks and ISDN was reviewed, and this featurewas included in the list for Revision A of IS-135 (800 MHz Cellular Systems TDMA Services for AsynchronousData and Fax).

A command was adopted to provide the ability to force a mobile terminated voice call to be answered as anasynchronous data to FAX call. This feature was included in the list for Revision A of IS-135. It was noted thatmobile manufacturers may wish to implement this command in their first implementation to provide forwardcompatibility.

TR-45.3.2/96.09.17.03© (A. Sacuta, TR-45.3.2 Chair, Ericsson) lists bugs and enhancements for IS-130 (800 MHzTDMA Cellular-Radio Interface – Layer-Two Logical Link Control – Radio Link Protocol 1) and IS-135 (800 MHzCellular Systems TDMA Services for Asynchronous Data and Fax). The 17 listed enhancements to IS-135 includeadditional cellular-based (e.g., SMS) and data modem (e.g., V.80) features.

TR-45.3.2/96.09.17.04© (D.N. Knisely, Lucent) is an addendum to IS-135 that supports the capability for a mobilesystem to arbitrarily answer a mobile terminated voice call as an IS-135 asynchronous data or fax call. Version 2 ofthis document is contained in TR-45.3.2/96.09. 18.01© (D.N. Knisely, Lucent).

TR-45.3.2/96.09.17.05© (A. Sicher, Ericsson and D.N. Knisely, Lucent) contains an IS-130/135-A Stage 1definition for circuit switched PDN (Packet Data Network) and ISDN access feature without using V series modemconnections between the IWF and the PDN.



TR-45.3.5 SPEECH SERVICES

TR-45.3.5 has been requested to initiate a program to standardize a new codec by 1998. They are seeking furtherdefinition of the requirements. There was discussion concerning half-rate codec, multi-rate codec, and use of trelliscoded modulation.

TR-45.3.5 is seeking clarification concerning the requirements needed to support TDD.

The committee letter ballot of PN-3731 (Interoperable Implementation Issues in IS-641) was completed with nocomments to be resolved. A motion to forward the ballot version of PN-3731 to TIA for publication as TSB-77 wascarried.

The TR-45.3.5 Chair (J. Gabor, Lucent) noted that P. Coverdale (Nortel) officially resigned as TR-45.3.5 Chairduring the previous closing TR-45.3 Plenary. J. Gabor gratefully acknowledged P. Coverdale’s efforts andcontributions during his tenure as TR-45.3.5 Chair and noted that his presence would be missed. He furtherannounced that M. Austin (BellSouth) had accepted the position of TR-45.3.5 Vice-Chair.

In a brief discussion relating to the topic of “new vocoders,” the Chair asked for a resolution to the potential “short-stopping” of the standards process, as had occurred in the past, asking the Carrier Community for assurances thatexpending of resources would not be obviated by another eleventh-hour submission. He re-emphasized the need fortotal disclosure of ideas as a collaborative effort.

In regards to this process, the Vice-Chair expressed a need for reasonable expectations relative to the 1998 vocoderrequest, indicating the possibility of forming an ad hoc group to study this.

TDD COMPATIBILITY WITH IS-641

Although the possibility of the codec becoming unstable when TDD tones are passed was suggested, M. Fatini(Nokia) presented a DAT (Digital Audio Tape) recording to TR-45.3.5 evidencing satisfactory operation. It wasdemonstrated that the operation between tones is performed autonomously by the TDD, and the codec appeared to beunaffected by the exercise. This TDD was connected to the mobile by a jack, as opposed to an acoustic coupler. Itwas still unclear how an acoustic coupler could be utilized due to the proliferation of shapes and sizes that wereavailable. Further, TR-45.3.5 agreed that a clearer definition of “Supports TDD” was needed, along with a definitionof the problem they were being asked to solve. This item was to be tabled, pending clarification from TR-45. Itwas anticipated that this advice will emanate from the CTIA legal counsel after interpretation of the FCC mandate.S. Bloebaum (Ericsson) volunteered to supply the outcome of the TDD tests in Sweden.

1997 WORK PLAN - 1998 V OCODER SUBMISSIONS

TR-45.3.5 agreed that a “half-rate codec” (the data rate may be higher [up to 6 kbit/s] than a traditional [4 kbit/s]half-rate coder), meeting or exceeding IS-641 within the 1998 expectation, was unrealistic; however, an “acceptable”version with a slightly degraded quality level might be possible. The targeted date for this submission could still bebeyond 1998, but no resolution was reached. M. Austin (BellSouth) expressed that advantages to a half-rate codecinclude reduced infra-structure requirements, plus the potential for a global standard since the European speech qualityrequirements are not as stringent as the US. J. Crockett (Texas Instruments) felt that DSP technology would allowan equivalent (to IS-641) half-rate codec in a time frame between 1998 and 2000. It was anticipated that there wouldbe an increase in power consumption due to increased MIPS (Million Instructions Per Second) but that the trade-offsin robustness and quality would be worth the battery shortfall.

TR-45.3.5 then listed several possibilities:• A half-rate codec (6.5 kbit/s aggregate)• A dual-rate codec, stepping from 8 to 4 kbit/s when channel conditions degrade• A multi-rate codec, stepping from 16 kbit/s for indoor use, to 8 kbit/s for nominal use, to 4 kbit/s as in the dual-

rate• A proposal to study trellis-coded modulation as a means to provide higher channel rates to support higher vocoder

rates.

K. Swaminathan (Hughes Network Systems) advised that typical end-to-end delays on a half-rate codec equal 100 ms.It was felt by some members that this could border on becoming excessive–in terms of user perception.



The speech quality issue for indoor use was then brought up. The Chair noted that landline PBX users wouldprobably expect higher quality than that which is presently available in cellular or wireless usage; therefore, the 16kbit/s proposal made more sense than a 1.5 multiple which would yield a 13 kbit/s codec.

It was agreed that milestones need to be established for whichever variant(s) might be chosen. The EVRC test planwill be used as a template for establishing timing parameters, quality levels and testing.

TR-45.3.6 ENHANCED VERSIONS OF IS-136

In summary, TR-45.3.6:• Continued work on the second addendum to IS-136, PN-3767, and PN-3768• Continued developing Stage 1 descriptions for the list of proposed features for inclusion in revision B of IS-136• Requested an appropriate meeting between members of TR-45.3.6, and TR-45.1 at the next meeting to facilitate

the common analog core document

ADDENDA FOR IS-136-A

The Plenary had two PNs to develop Addenda to correct errors in IS-136-A: PN-3767 for IS-136-A Part 1 and PN-3768 for IS-136-A Part 2.

The Addenda Ad Hoc Group distributed copies of the following contributions from their meeting on September 17:

TR-45.3.6AAH/96.09.17.01© (Ericsson, presented by J. Diachina) identifies the set of adopted IS-136-A Addendumcontributions as well as contributions that have been updated but not formally adopted. The contribution wasaccepted for information as amended.

TR-45.3.6AAH/96.09.17.02R1© (Ericsson, presented by J. Diachina) proposes a solution to the problem related toMSID (Mobile Station Identity) assignment for unactivated MSs (Mobile Stations) that covers all possible scenariosand requires minimal MSC support. The contribution was accepted for the addendum.

TR-45.3.6AAH/96.09.17.03R1© (Ericsson, presented by J. Diachina) proposes clarification to the IS-136 text withrespect to data/fax support in Table 3.7.1-1. The contribution was accepted as amended for the addendum. The Chairwill also recommend to the Plenary that this contribution be sent to TR-45.1 in a liaison.

TR-45.3.6AAH/96.09.17.04© (Ericsson) proposes changes to the IS-136 text to clarify the terminology used todescribe the “SMS” teleservice. The suggested text was accepted as an editorial change.

TR-45.3.6AAH/96.09.17.05R1© (B. Daly, AT&T) proposes modifications to the OATS Addendum. After review,the contribution was accepted as amended for the addendum.

TR-45.3.6AAH/96.09.17.06 (Ericsson) presents concerns regarding the DVCC (Digital Verification Color Code)value of 45. During the review, the following amendments were proposed in the Recommendation section:• Line 1, change “Rev. B” to “Rev. A”• 2nd paragraph, lines 3-5 delete “In interest of serving......to determine slot type” and replace it with “It is strongly

recommended that MSs not use CRC analysis as the sole method of distinguishing between F-BCCH andSPACH slots. Furthermore,”

The contribution was accepted as amended for the addendum.

IS-136-A

TR-45.3 .6 /96 .09.18.06 (C. Coursey and T. Watts, Southwestern Bell) proposes modifications to IS-136-Aregarding interpretation of the Initial Selection Control flag and the use of a “best list” of last used DCCHs (DigitalControl Channels) in the selection algorithm. It supersedes TR-45.3 .6 /96 .06.17.11 (C. Coursey,Southwestern Bell) and TR-45.3.6/96.07.09.06© (J.C. McQueen, Southwestern Bell) which had been carriedforward. The contribution was accepted as amended for the addendum.

TR-45.3.6/96.09.18.04© (J. McQueen, Universal Wireless) requests a new SOC (System Operator Code) andInternational SOC assignment for Telecom Mobile Communications Limited of New Zealand in Annex B of IS-136-A. After discussion, the SOC code assigned was 001 for New Zealand. The International SOC assignment was 806.The contribution was accepted for the addendum as amended.

TR-45.3.6/96.09.18.05© (D. DeVaney, Astronet) provides a comparison of IS-136-A with the proposed TIA-553-AAuthentication text. His comparison of the two documents reveals a significant number of differences in the text.The text in IS-136-A is also different from the original IS-54-B. After discussion, an ad hoc group was assigned to



meet with TR-45.1 in October. The Chair will request this joint meeting at the Plenary. The contribution wascarried forward.

TR-45.3.6/96.09.18.09© (A. Talwalkar, Lucent) provides Annex E for inclusion in the Addendum 2 of IS-136.1-A.It supersedes TR-45.3.6/96.07.09.09© (E. Henrikson and A. Talwalkar, Lucent). The purpose of this Annex is todemonstrate a calculation procedure for estimating the R-DATA message length that can be sent over air interface andto determine the size of the User Data Unit in an SMS (Short Message Services) teleservice message. After discus-sion, the second and third lines of the page with “2) Limitations on OATS Teleservice Messages” at the top wererewritten as follows: “Thus, OATS messages are limited to 133 to 183 octets. Typically, OATS would not usesubaddressing, so the 183 octet limit is practical.” The contribution was then assigned to the Addenda Ad Hocgroup.

TR-45.3.6/96.09.18.16© (C. Kahn and A. Talwalkar, Lucent) modifies the Response to Overhead Informationprocedure in IS-136.2 to prevent IS-136 mobiles from registering on the ACC (Analog Control Channel) prior toreading the Control Channel Information message and accessing a DCCH. After discussion, line 11 had thefollowing phrase added: “and the MS desires ACC service.” The contribution was accepted for the addendum asamended.

The following issues were identified as outstanding obstacles to the completion of the second addendum:• SOC/BSMC (Base Station Manufacturer Code) on F-BCCH (Broadcast Control Channel), TR-

45.3.6/96.09.18.12. Assigned to AT&T WS.• Remaining Length Indicator, TR-45.3.6/96.08.13.04. Assigned to AT&T WS.• Annex E, TR-45.3.6/96.09.18.09.

T. Watts (Southwestern Bell) reported that the IS-41 Task Group was working on a Stage 3 description for theDCCH plus a TSB for PCS support.

PROPOSED IS-136-B F UNCTIONALITY

This topic is a collection point for potential services.

TR-45.3.6 authorized an ad hoc group to preview proposed IS-136-B functionality. The Chair was to send out apacket of the IS-136-B materials to the ad hoc members. The primary goal was to prepare contributions for theSeptember meeting to justify applying for PNs. The meeting was scheduled for Friday, August 30. J. McQueen(Universal Wireless) chaired the ad hoc.

TR-45.3.6/96.09.18.03© (J. C. McQueen, Universal Wireless) provides Stage 1 Descriptions for the current list ofProposed IS-136-B New Functionality. The contribution lists thirteen Stage 1 descriptions. The followingcontributions are referenced to these descriptions.

TR-45.3.6/96.09.18.18© (S.J. Willhoff, Nokia) presents a mechanism to refine the signal strength reporting ofMAHO (Mobile Assisted Handoff) channels, allowing greater accuracy for handoff decisions whenever multiple chan-nels are measured at greater than 51 dBm. This contribution applies to number 1a (Enhanced MAHO DynamicRange) in TR-45.3.6/96.09.18.03©.

TR-45.3.6/96.09.18.11© (S.J. Willhoff, Nokia) presents a service definition for the IS-136 SMS Broadcast feature.Layer 2 functionality, Layer 3 messages, and the Higher Layer Protocol Data Unit are discussed. This contributionapplies to number 2 (Broadcast SMS) in TR-45.3.6/96.09.18.03©.

TR-45.3.6/96.09.18.13© (S.J. Willhoff, Nokia) provides a Stage 1 proposal for DTX/CNI (DiscontinuousTransmission/Comfort Noise Insertion) Feature operation in IS-136-B. A summary report on tests of channelactivity conducted using the GSM (Global System for Mobile Communications) EFRC (Enhanced Full Rate Codec)was included for background. In addition, a tape was available to demonstrate the proposed feature. Thiscontribution applies to number 3 in TR-45.3.6/96.09.18.03©, new vocoder for 1998 time frame.

TR-45.3.6/96.09.18.10© (P.W. Nurse, Lucent) proposes text for Stage 1 and Stage 2 description for an SMSfragmentation and reassembly function identified as a candidate for inclusion in IS-136-B. It applies to number 8(Proposed Enhancements to Provide a New Messaging Teleservice) in TR-45.3.6/96.09.18.03©.



TR-45.3.6/96.09.18.17© (Ericsson) presents a Stage 1 definition of an enhanced teleservice transport mechanismthat can carry existing teleservice messages as well as future (to be defined) teleservices. This Generic EnhancedTeleservice Transport (GNATT) is intended to solve the limitations of the existing teleservice transport. Thiscontribution also applies to number 8 in TR-45.3.6/96.09.18.03©.

Number 10 (Originating SMS on a DTC) of TR-45.3.6/96.09.18.03© includes in the second paragraph a referenceto a Nokia ballot comment. This reference was withdrawn since the functionality was covered in number 8 of TR-45.3.6/96.09.18.03©.

There was discussion concerning a Stage 1 description. It was observed that delivery of multi-fragment SMS on thecontrol channel may be slow considering the current mobile station state transition diagram. It was observed thatdelivery of multi-fragment messages would be more efficient on the DTC (Digital Traffic Channel) and that currentIS-41 SMDPP (Short Message Delivery Point-to-Point) messages contain an indicator for more messages whichmay be used by the MSC (Mobile Switching Center) to assign a DTC. There was discussion concerning support ofoverlapped transmission and of the role of intermediate nodes in the transmission path. Stage 1 descriptiondevelopment was assigned to B. Daly (AT&T).

Number 11 (performance data) of TR-45.3.6/96. 09.18.03© remained on the IS-136-B list with no discussion.Number 12 (Enhanced Voice Privacy) remained on the list with strong support, and a Stage 1 description wasassigned to B. Daly (AT&T). Item 13 (Smart Antennas) was viewed as conditional. The standards impact of smartantennae was not clear. No support was expressed for maintaining this item. It was agreed to carry this itemforward; if no contributions are received at the next meeting, this item will be dropped from the IS-136-B list.

TR-45.3.6/96.09.18.14© (B. Daly, AT&T) raises four issues with the current MSID selection criteria. It wasaccepted as new number 18 in TR-45.3.6/96.09.18.03©, “IMSI Use in the US.”

TR-45.3.6/96.09.18.15© (B. Daly, AT&T) proposes modifications to IS-136 for an OAA (On Air Activation)reprogramming scenario. It was accepted as new number 19 in TR-45.3.6/96.09.18.03©, “OAA Re-programming.”It also raises the issue of the Remaining Length field. Three proposals were discussed: force octet alignment byintroducing two bit Protocol Discriminator before message type, start count at the bit following the RemainingLength field, and start count at the next octet boundary after the Remaining Length field. It was agreed to carry thisitem forward.

A new number 14 was added to the IS-136-B list, “Support of DTX and CNI.” The relevant contribution was TR-45.3.6/96.09.18.13©. A new number 15 was added to create alignment between the analog sections of IS-136 andTIA/EIA 553-A. A new number 16 was added, “Encryption on DCCH.” And a new number 17 was added to create aseparate document for the description of teleservices. Strong support was expressed for number 4 (Mobile StationLocation Reporting Teleservices) since it is needed for E-911 service. The Ad Hoc Group on potential IS-136-Bservices will continue.

CALCULATION OF MAXIMUM R-DATA MESSAGE LENGTHS FOR IS-136 (PN-3719)

TR-45.3.6/96.09.18.08© (E. Henrikson and A.T. Talwalkar, Lucent) recommends changes to the R-DATA messagelength table for IS-136.1-A. After discussion, the R-DATA message length for the value “100” was changed from“205” to “204” octets. This contribution, along with TR-45.3.6/96.08.13.03© (B. Daly, AT&T) from last meetingwere assigned to the Addenda Ad Hoc Group.

SOC/BSMC IDENTIFICATION ON THE F-BCCH

TR-45.3.6/96.08.13.05© (B. Daly, AT&T) deals with the SOC/BSMC (Base Station Manufacturer Code)Identification on the F-BCCH (Broadcast Control Channel). Currently the transmission of SOC/BSMCIdentification is optional on both the F-BCCH and the E-BCCH. In order to improve selection time, it was desiredthat the SOC/BSMC Identification be mandatory on the F-BCCH. During the discussion, it was agreed that thiswas a second addendum issue, and it was referred to the Addenda Ad Hoc Group.

OTHER HIGHLIGHTS

TR-45.3 .6 /96 .09.18.07 (P. Reddy and T. Watts, Southwestern Bell) proposes to use the Message ReferenceInformation Element to define categories for different types of messages that may be sent to an MS in order for thesubscriber to be able to screen the categories for presentation. Compatibility concerns were expressed in the case ofan old MC (Message Center) communicating with a new MS. The proposed message modification would allow anold MC to inadvertently advise a new MS of a category that the old MC did not support. It was agreed to add an ap-



propriate note to require that if urgency = bulk, then both delivery and manual acknowledge shall not be required.The contribution was carried forward and considered an addendum item.

TR-45.3.6/96.09.18.12© (S.J. Willhoff, Nokia) identifies four issues existing in IS-137-A. It was carried forwardwith a view to apply for a PN to address the issues raised at the next meeting.

TR-45.1 was co-located with this meeting and held a joint meeting (reported in the TR-45.3.6 section, below). TheIPR (Intellectual Property Rights) statement was read. Lucent Technologies and Ericsson responded that they mayhave IPR. D. Holmes of AT&T Wireless expressed his thanks to TR-45.3 in their support of the development ofIS-136 (800 MHz TDMA Cellular - Radio Interface - Mobile Station - Base Station Compatibility - TrafficChannels and FSK Control Channel) and their roll-out of IS-136 services as of October 2.

TR-45.3/96.10.16.03© (P.W. Nurse, TR-45.3 Chair, Lucent) contains incoming correspondence as follows:• From F. Lucas, TR-30.2 Chair, dated September 11, 1996. This letter addresses the ballot comments for SP-

3138, DTE/DCE Interface for Digital Cellular Equipment. All ballot comments were resolved by TR-30.2except for OKI comments desiring a different connector. TR-30.2 asks TR-45.3 if they support the OKIposition. Since OKI is not an active member of TR-45.3, there was little that TR-45.3 could do. A reply willbe drafted.

• A copy of a letter from S. Azhar, TIA Standards Secretariat, to D. R. Bolgiano of InterDigital, dated September6,1996. It requests that InterDigital comply with TIA IPR (Intellectual Property Rights) policy with respect toIS-136.1-A and identify any InterDigital IPR. It was accepted for information.

TR-45.2 L IAISON

TR-45.2 met last week. Five documents were in V&V: PN-3769 (Intersystem Operations Support for Over-the-AirCapabilities), PN-3579 (IS-41/DCCH, Intersystem Operations Support for the IS-136 Digital Control Channel),PN-3770 (Intersystem Operations Support for Data Services) & associated work, and CDMA support. TR-45.2 wasstill working on SP-3588 (Cellular Radio Telecommunications Intersystem Operations, ANSI version of IS-41-C)and PN-3293 (IS-124-A, Cellular Radio Telecommunications Intersystem Non-Signaling Data CommunicationsStandard). TR-45.2.1 was working on Stage 1 of SMS Broadcast (TR-45.3 will provide their input). The CTIA(Cellular Telecommunications Industry Association) is meeting on November 18 to discuss network security ofintersystem messages. The Royal Canadian Mounted Police attended the last meeting to discuss electronicsurveillance. A legal summit on surveillance was scheduled on October 29 in Washington, DC.

AHAG LIAISON

TR-45.3/96.10.16.05© (S.J. Willhoff, Nokia) presents the October AHAG liaison report. AHAG met during theprevious week and will co-locate with TR-45.3 in November. The AHAG session with NSA Export Control wasnot held. It is expected to occur in October.• Mitre reported on its progress on Wireless Security Assessments. They have finished IS-136 and begun IS-95-A

(expected completion in the Spring of 1997). PCS 1900 is expected to be completed in the Summer of 1997.Enhancements in IS-136-B or IS-95-B would be reviewed separately. No intermediate results will be released.

• The AHAG and a newly formed TR-45.2 Ad Hoc will work jointly on Network Security. An initial meeting isto be held the week of November 11 in Dallas to devise a work plan. This is an outgrowth of the CTIAIntersystem Messaging Security Forum.

• The AHAG discussed issues relating to TR-45.3 Service Programming lock Code (SPC). An initial response toCMEA encryption issues for SPC was drafted. Lucent, Nokia and CDG have proposals that will be discussed atthe next meeting.

• A question was raised on the ANSI ballot for TIA-627 (TSB-47 + IS-54-B). Appendix A was not mailed outwith this ballot. The AHAG approved another version of Appendix A in March. P. Nurse (Lucent) and S.Willhoff (Nokia) will verify this.



AD -HOC GROUP ON ITU LAND MOBILE HANDBOOK

TR-45.3/96.09.17.08© (J.C. McQueen, Universal Wireless) from the September Plenary was adopted as therecommended TDMA section of the handbook; this item was closed.

OTHER HIGHLIGHTS

Feedback to TR-45 with respect to support of TDD (Telecommunications Devices for the Deaf) had been remanded toTR-45.3.5, but there was no feedback to date. It was carried forward. The TDMA vocoder may not pass thenecessary tones through, but a specialty modem will make it work (for a premium).

TR-45.3/96.10.16.06 (E.D. Ornelas, NEC America) proposes a response to AHAG’s request for updatedinformation on projects as they relate to security/privacy (TR-45.3/96.09. 17.03©, AHAG correspondence date July1,1996). This contribution lists all PNs currently assigned to TR-45.3, a short description of each and an indicationof what level of security, if any, applies. The item was carried forward with E. Ornelas (NEC America), P. Nurse(TR-45.3 Chair, Lucent), and S. Willhoff (AHAG Liaison, Nokia) cooperating on liaison and feedback.

TR-45.3.6 reported a that a response to NSMA (National Spectrum Managers Association), TR-45 and TR-46.2.1with respect to PCS-PCS Interference (PN-3777) as described in TR-45/96.08.29.03© (D. Lee, NSMA WG 20Chair, BellSouth) was provided in TR-45/96.08.28.33 (included in TR-45.3/96-09-17-06). This responseprovides the work plan on PN-3777 and a copy of the August draft of PN-3777.

It was reported that TR-45.5 was cooperating on the building of a generic performance model. T. Watts(Southwestern Bell) suggested that TR-45.3’s minimum performance standards be used to build a similar model.However, there was no interest in working on such a project.

TR-45.3.5 SPEECH SERVICES

M. Austin of BellSouth (Vice Chair of TR-45.3.5) chaired this meeting.

There was discussion on TDD compatibility, but no contributions. It was noted that TR-45.3.5 has a similarvocoder to GSM (Global System for Mobile Communications), and it appears to be acceptable.

DTX (Discontinuous Transmission) contributions were due in November. In addition, Nokia is working on comfortnoise.

1997 Work Plan (continued from the September meeting):• After 2000, half rate should be wireline quality.• Full rate is not standardized.• Multi-rate (6 kbit/s & 12-13 kbit/s) to use half rate on good channel and full rate when channel quality decreases.Testing/monitoring is ongoing, with standardization expected in 1999. TR-45.3.5 intends to improve data rates tomatch their advanced modulation. They intend to look at DTX first then expand the scope for other modulation op-tions. TR-45.3.5 wants carriers to review their work plan and provide feedback on capacity versus voice qualitypreferences through 1999.

A detailed document on ETSI review of GSM speech quality issues and future directions, June 24, 1996(unnumbered, CSR-45.3.5/96.10-unn), was provided for information. It notes that the Enhanced Full-Ratecodec (also used in US PCS 1900) achieves wireline performance under low error conditions. There is some interestin ETSI in an improved EFR codec but there is also concern over more codec proliferation. Multi-Rate codecs is thepreferred development direction in this paper; a number of different approaches are discussed.

TR-45.3.6 ENHANCED VERSIONS OF IS-136

IS-136-A

The Plenary had two PNs (PN-3767 for IS-136-A Part 1 and PN-3768 for IS-136-A Part 2) to develop Addenda tocorrect errors. TR-45.3.6/96. 10.15.13© (Ericsson) contains a draft set of IS-136-A Addendum replacement pagescovering the items adopted to date. The title was corrected to read IS-136 instead of IS-36. After discussion, thecontribution was accepted for information pending changes anticipated in this meeting.

TR-45.3.6/96.10.15.02© (B. Daly and M. Moore, AT&T) proposes not to make changes outlined in TR-45.3.6/96.08.13.06© (B. Daly, AT&T) to IS-136.1-A to store the current DCCH and the first three neighbor listentries received within the Neighbor Cell message. This contribution restores the text in IS-136-A. After



discussion, it was accepted. TR-45.3.6 requested the Editor to double check that this was the only change made topage 173.

TR-45.3.6/96.10.15.03© (B. Daly and M. Prise, AT&T) is an update to TR-45.3.6/96.08.13.05© (B. Daly and M.Prise, AT&T) to include SOC/BSMC (System Operator Code/Base Station Manufacturer Code) Identification on theF-BCCH (Broadcast Control Channel) as mandatory. After initial discussion, the contribution was carried forward tolater in the week. TR-45.3.6/96.10.15.03R1© was submitted the following day. After discussion, someamendments were made. The contribution was accepted as amended.

TR-45.3.6/96.10.15.05© (B. Daly, AT&T) finalizes discussions at the September meeting regarding proposedadditions to the OATS NAM (Number Assignment Module) data block to download a directory number. Thediscussion that followed centered on decoupling this from MIN (Mobile Identification Number) and IMSI(International Mobile Station Identity). B. Daly was requested to amend the contribution to reflect this concern. Onthe following day, TR-45.3.6/96.10.15.05R1© (B. Daly, AT&T) was submitted. After discussion, the contributionwas accepted as amended.

TR-45.3.6/96.10.15.06© (B. Daly, AT&T) proposes adding a Teleservice Server Address to the NAM download inOATS. Specifically, this means adding a temporary address during over-the-air activation which may be trouble ifthe message is interrupted by a dying battery. B. Daly was requested to consider revising the contribution. On thefollowing day, TR-45.3.6/96.10.15.06R1© (B. Daly, AT&T) was submitted. After discussion, the contributionwas accepted as amended.

TR-45.3.6/96.10.15.08© (B. Daly, AT&T) proposes that carrier specific teleservices be reserved by a carrier andproposes that this be documented in IS-136. IS-136 defines HLPIs (Higher Layer Protocol Identifiers) for carrierspecific teleservices. When a carrier decides to use a carrier specific teleservice, there is some uncertainty in themobile station as to which carrier the teleservice is assigned. Thus, carrier specific teleservices must be reserved by acarrier, and this should be documented in IS-136. After discussion, the contribution was accepted as amended.

TR-45.3.6/96.10.15.14© (J. Ragsdale, Ericsson) proposes to reinstate the 2-bit Protocol Discriminator InformationElement (IE) as the first IE in the OATS messages and thereby restore the Remaining Length IE to octet alignment.Presently, each OATS message contains a 6-bit Message Type IE as the first IE followed by an 8 bit RemainingLength Information Element. This causes the Remaining Length IE to cross an octet boundary and cause ambiguousinterpretations of the meaning on Remain Length. After discussion, the following recommendation was made: the16 bit length specified in Annex E should be maintained, and a note should be added in the Remaining Length IE inSection 7.1 that refers to the length in Annex E. The contribution was accepted as amended.

TR-45.3.6/96.10.15.16© (Nortel, Vanguard, and Century Cellunet) contains a formal request for SOC codeassignments for Vanguard and Century Cellunet. It was presented by K. Wiemann of Nortel. The contribution wasaccepted with a reminder that codes for New Zealand Telecom Limited had also been assigned.

TR-45.3 .6 /96 .10.15.19 (Ericsson) recommends changing the value of the function of “reserved for SOC/BMSCSpecific Signaling” from “110” to “100” in the VC (Virtual Container) field within the Voice Mode IE in IS-136.1-A. It was presented by J. Diachina, Ericsson. In IS-136.1-A, “Reserved for SOC/BMSC Specific Signaling”appears not to be used within the context of the Voice Mode IE. The contribution was accepted for the addendum.

TR-45.3.6/96.10.15.13© (Ericsson), a draft set of IS-136-A Addendum replacement pages, will be updated with theaccepted changes for the addenda; the Chair will distribute hard and soft copies to the members on or beforeNovember 8. The member companies will then conduct V&V on the document in preparation for recommending thePNs for ballot in the November meeting.

IS-41 T ASK GROUP LIAISON REPORT

T. Watts (Southwestern Bell) reported that the IS-41 Task Group was conducting V&V on October 17 and 18 on theproposed TSB for DCCH support in IS-41. Data and Group 3 fax is also in V&V.

PROPOSED IS-136-B F UNCTIONALITY

This topic is a collection point for potential services.

TR-45.3.6 agreed to move all performance data from IS-136 Parts 1 and 2 to the appropriate minimum performancestandard in the IS-136-B time frame.



TR-45.3.6/96.10.15.07© (B. Daly, AT&T) proposes a method of handling the A-key in abort or error scenarios inthe OATS teleservice process. In the OATS teleservice process, the A-key is committed to permanent memoryimmediately after completing the Diffie-Hellman process. If the NAM Commit fails, however, the A-key will stillhave been updated in the mobile. For error cases, it is desirable that a mechanism be established to revert back to the“old” A-key value. After discussion, TR-45.3.6 recommended that the contribution be included in the potential IS-136-B work list.

TR-45.3.6/96.10.15.09© (D. DeVaney, Astronet) proposes changes to reduce dropped calls on handoff. The changeproposed is to allow the mobile to return to the original base station and report the condition encountered. It wascarried forward. After discussion, it was recommended that the contribution be included in the potential IS-136-Bwork list.

CALCULATION OF MAXIMUM R-DATA MESSAGE LENGTHS FOR IS-136 AND RELATED ANNEX EISSUES (PN-3719)

TR-45.3.6/96.10.15.04© (B. Daly, AT&T) provides text for Annex E of IS-136-A describing the limits on user datain R-Data and SMDPP (Short Message Delivery Point-to-Point) and its impact on the length of OATS (Over-the-Air-Activation TeleService) messages that can be sent to or originated from a mobile station. TR-45.3.6/96.07.09.09© (E. Henrikson and A.T. Talwalkar, Lucent) also proposed an Annex E for IS-136.1-A and wassuperseded by this new contribution. The contribution was initially reviewed and amended but then was supersededby TR-45.3.6/96.10.15.18© (E. Henrikson and A.T. Talwalkar, Lucent) which also provides text for Annex E forinclusion in IS-136.1-A, as amended.

TR-45.3.6/96.10.15.11© (E. Henrikson and A.T. Talwalkar, Lucent) recommends changes to R-DATA messagelength for inclusion in the Addendum to IS-136.1-A. It was presented by A. Talwalkar of Lucent and B. Daly ofAT&T. After discussion, the contribution was initially reviewed but then was superseded by TR-45.3.6/96.10.15.20© (E. Henrikson and A.T. Talwalkar, Lucent) which recommends limits on R-DATA messagelength on DTC for IS-136.

TR-45.3.6/96.10.15.20© (E. Henrikson and A.T. Talwalkar, Lucent) recommends limits on R-DATA messagelength on DTC for IS-136. It was presented by A. Talwalkar of Lucent. After discussion, the contribution wasaccepted as amended.

TR-45.3.6 recommended that the work generated above be incorporated in the Cleanup Addenda. PN-3719(Implementation Aspects concerning the use of the R-Data Message in IS-136) will be closed due to inactivity.

SOC/BSMC IDENTIFICATION ON THE F-BCCH

TR-45.3.6/96.08.13.05© (B. Daly and M. Prise, AT&T Wireless Services) deals with the SOC/BSMCIdentification on the F-BCCH and had been carried forward for further investigation. Upon further review, it wasdetermined that this contribution had been covered by TR-45.3.6/96.10.15.03© (B. Daly and M. Prise, AT&T)above.

OTHER HIGHLIGHTS

TR-45.3.6/96.09.18.17© (Ericsson) presents a Stage 1 definition of an enhanced teleservice transport mechanismthat can carry existing teleservice messages as well as future (to be defined) teleservices. This Generic EnhancedTeleservice Transport (GNATT) is intended to solve the limitations of the existing teleservice transport. P. Reddy(Southwestern Bell) brought in TR-45.3 .6 /96 .10.15.17 , Short Message Service Bulk Message Categories (P.Reddy and T. Watts, Southwestern Bell), which proposes to use the Message Reference IE to define categories fordifferent types of messages that may be sent to an MS in order for the subscriber to be able to screen the categoriesfor presentation. It supersedes TR-45.3.6/96.09.18.17©. After discussion, P. Reddy submitted TR-45 .3 .6 /96 .10 . 15 .17R1 to reflect the group’s input. This paper is a proposal for TDMA; it presents the way inwhich an IS-136 mobile should display SMS messages categories that are of only bulk-priority. This document alsoexplains how Message Centers should format SMS messages categories and send it in an SMD-PP message to amobile. TR-45.3.6 decided to carry forward the revised contribution for further review.

TR-45.3.6/96.09.18.12© (S.J. Willhoff, Nokia) identifies four issues existing in IS-137-A. It was carried forwardfrom the September meeting. TR-45.3.6 recommended that a PN be requested in Plenary to begin work on an adden-dum for IS-137-A as related to this contribution.



TR-45.3.6/96.09.18.15© (B. Daly, AT&T) proposes modifications to IS-136 for an OAA (On Air Activation)reprogramming scenario. It had been carried forward from the September meeting. After further review, it wasdecided to assign it to the potential IS-136-B work list.

The September Plenary assigned the following items to this working group for review:• NAG correspondence of July 31, 1996 -- TR-45.3.6 recommended that the following statement be sent: “There is

currently no interface between the MSC and the message center. At this time we do not have any othercomment.”

• TR-45.3.6 had been asked to review PN-3777. After initial review, the document was found to contain historicalperformance data from the concerned standards. This created a problem since the superseded J standards had beenreferenced. M. Hosford (Lucent) agreed to carry current copies of TR-45.3.6’s standards to TR-46.2.1 (the groupworking on PN-3777). In addition, M. Hosford stated that a later version of the PN (version .31) was what TR-45.3.6 should be reviewing. It was recommended that the TR-45.3 Chair send a letter to TR-46 indicating thatcopies of TR-45.3’s performance standards are being sent to them as a liason and requesting a copy of the latestversion of PN-3777 for TR-45.3.6’s review and comment.

• TR-46.2.1 requested actual performance data for mobile and base stations from individual manufacturers fordeveloping curves to measure potential interference. After discussion, the following response was recommended:“The data requested is company-specific so that TR-45.3 has no control over it. We encourage our members toparticipate in TR-46.2.1.”

• Spurious Interference Correspondence -- After review, TR-45.3.6 recommended that coordination was needed todeal with the emerging concerns related to this subject.

TR-45.3.6/96.10.15.15© (P.W. Nurse, Lucent) proposes use of a HTML (Hyper Text Markup Language), or aproper subset, to support the soft-key download feature. After discussion, TR-45.3.6 decided to carry thiscontribution forward to the next meeting.

TR-45.1.1 AND TR-45.3.6 JOINT MEETING

TR-45.1.1 and TR-45.3.6 held a joint meeting to discuss the alignment of text between PN-3598 (800 MHz AnalogCellular Systems Mobile Station – Base Station Compatibility) and IS-136. TR-45.3.6/96.10.15.10© (D.DeVaney, Astronet) provides a review of PN-3598 Section 2.3.12 (authentication and encryption); TR-45.3.6/96.10.15.12© (Ericsson) lists two SP-3598 inconsistencies associated with IS-136. Both contributions report oncompatibility comparing IS-136 and TIA-553-A.

The joint meeting agreed to present TR-45.3.6/96.10.15.10© and the discussion items to TR-45.1.1 for theirconsideration and review by TR-45.5.

In TR-45.3.6/96.10.15.12©, it was noted that page and line numbers do not match up with the September 15version that the contribution references. The two items, Update Overhead Information and Location Areas, werediscussed.

A conference call was recommended to review Abbreviated Alert, Message Waiting, Disable DTMF, Page onForward Voice Channel, and Awaiting for Order Timer. TR-45.3.6 reviewed these items but wanted additional timefor a more thorough review. In addition, Sections 2.6.1.1 and 2.6.3.7 (Area Location) were to be reviewed to seedifferences between IS-136 and IS-95-A (Mobile Station-Base Station Compatibility Standard for Dual ModeWideband Spread Spectrum Cellular System).

REPORT OF TR-45.4 MICROCELL/PERSONAL COMMUNICATIONSSERVICES STANDARDS

SEPTEMBER 30 – OCTOBER 4, 1996, CHICAGO, ILThis TR-45.4 meeting focused on issues relating to PN-3539 (MSC-BS [A-Interface] for Public 800 MHz, IS-634Revision A, enhancement to IS-634).

TR-45.4/96.09.30.02 is outgoing correspondence to TIA noting that TR-45.4 has voted to send PN-3662 (TSBfor Discrepancies and Enhancement to MSC-BS Interface for Public 800 MHz, IS-634) as a TSB associated with IS-634 for publication as TSB-80.

TR-45.4/96.09.30.03 is outgoing correspondence to the TR-45.5 Chair, J. Alphonse (Ameritech), regardingStage 1 system selection for preferred roaming and service programming lock feature descriptions. TR-45.4 reviewedthe features descriptions and had the following comments:

• It is conceivable that while changing the SPC (Service Programming Code), the process may be intentionally orunintentionally interrupted resulting in the SPC being inadvertently changed to an unknown code. If this occurs,the mobile will be rendered inoperable, and the service provider may be liable to replace the mobile.Consequently, consideration should be given to including a requirement that mobile manufacturers implement thefunction in a manner that will ensure that if the procedure of changing the SPC is intentionally orunintentionally interrupted, the mobile will default to the SPC that was in effect just prior to the failed attemptto change the SPC.

• Recent actions by the FCC on number portability may impact programming lock. For example, considerationmay need to be given regarding how the SPC would be transferred from one service provider to another.

TR-45.4/96.09.30.04 is outgoing correspondence to the TR-45 NAG Chair, A. G. Gardner (Ericsson). TR-45.4reviewed the TR-45 Network Reference Model (NRM). According to the guidelines, terms and acronyms used tolabel functional entities or functional reference points should not have physical connotations. As indicated in aprevious liaison, TR-45.4 felt that the term MSC (Mobile Switching Center) had evolved to the point where theterm now implies a physical connotation. It was recommended that the NAG add text to emphasize the functionalnature of the reference model as contained in an attachment to the correspondence. In addition, TR-45.4 proposeschanging the MSC element to identify the component functionalities. These changes would allow TR-45 tocontinue to use essentially the same NRM to encompass work to support the ISDN-based A-Interface as well asWireless Local Loop (WLL).

TR-45.4/96.09.30.05© (M. Dolan, Lucent) proposes a liaison to the TR-45 NAG that indicates the addition of anew reference point between the IWF (Inter-Working Function) and BS (Base Station) be shown as the X referencepoint. There was considerable discussion with resolution.

TR-45.4.2 MSC-BS (A-I NTERFACE)

TR-45.4 .2 /96 .10.01.03 is the PN-3539 working draft (IS-634-A) as of September 30, 1996.

TR-45.4.2/96.10.01.04© (L. Milton and G. Kfoury, Motorola) proposes 12 areas of work that need to be addressedin order to complete the specification for using ATM (Asynchronous Transfer Mode) transport for signaling and usertraffic over the IS-634 A-Interface. Motorola is very interested in pursuing the use of ATM technology with respectto the IS-634 A-Interface and would like to work in applying ATM to wireless systems.

TR-45.4.2/96.10.01.05© (L. Milton and G. Kfoury, Motorola) proposes adding the Information Records element tothe SETUP, FLASH with information and FEATURE NOTIFICATION messages. It was noted that this is IS-95specific (Mobile Station - Base Station Compatibility Standards for Dual-Mode Wideband Spread Spectrum Systems)and was carried forward to the next meeting.

TR-45.4.2/96.10.01.06© (R. Krishnamurthi, Qualcomm) describes the need for a new message called an Alert withInformation Message that flows from the MSC to the BS. It was accepted with modification.

TR-45.4.2/96.10.01.07© (R. Krishnamurthi and E. Tiedemann, Qualcomm) proposes messages description andlayout for the PMC PwrControl Configuration Request and PMC PwrControl Configuration Response messages,which are exchanged between the PMCC (Packet Mode Call Control) and SDU (Selection/Distribution Unit,previously packet mode channel handler) on the A4 interface which handles both control signaling for the SDU andmessages going to the MS. It was accepted.



TR-45.4.2/96.10.01.08© (C-P. Hsu and R. Krishnamurthi, Qualcomm) proposes text changes for the CDMA softhandoff addition procedures to support alternative architectures in PN-3539. It also supports adding multiple cells inone A1 transaction. It was adopted with some modifications. Additional contributions are expected.

TR-45.4.2/96.10.01.09© (C-P. Hsu and B. Mohanty, Qualcomm) proposes text for the CDMA Traffic Channelassignment procedure to support alternative architecture in PN-3539. It was accepted with modifications.

TR-45.4.2/96.10.01.10© (R. Krishnamurthi and E. Tiedemann, Qualcomm) proposes message description andlayout for the PMC Connection Established Message exchanged between the PMCC and SDU on the A4 Interface.It was accepted.

TR-45.4.2/96.10.01.11© (J. Wang and R. Krishnamurthi, Qualcomm) presents IS-634 modifications for support ofTMSI (Temporary Mobile Station Identity) in the wireless system. It was to be modified and resubmitted.

TR-45.4.2/96.10.01.12© (R. Krishnamurthi, Qualcomm) proposes the text describing operational procedures andmessages for the A4 Interface that had been accepted for inclusion in PN-3539. It was accepted.

TR-45.4.2/96.10.01.13© (R. Krishnamurthi and B. Mohanty, Qualcomm) proposes text for a new informationelement called CALL-REF. CALL-REF provides a globally unique identification for the call. It was accepted withmodifications.

TR-45.4.2/96.10.01.14© (M. Dolan, Lucent) proposes protocol stack options for signaling on the A1, A3, and A4Interfaces. Included in this proposal is the use of TCP (Transmission Control Protocol) as a transport protocol.Standard versions of TCP/IP (Internet Protocol) are indicated, although exact references were still to be provided. Inaddition, scenarios showing standard TCP connection establishment and clearing were also to be provided.

TR-45.4.2/96.10.01.15© (M. Dolan, Lucent) aligns the existing Packet Mode Channel (PMC) messages inSections 2.9 and 2.10 with the A-Interface architecture adopted in the September 9, 1996, meeting of TR-45.4.2. Inparticular, it assumes the use of a Call Reference element to identify the call instance among the network elements.This leads to the removal of the PMCH (SDU) Address, PMCE (Packet Mode Channel Element) Address, etc.Instead, it is assumed that the A3 and A4 signaling connections are independent of the underlying transport protocol.Appropriate elements (e.g., A3 Traffic Circuit ID, A3 Traffic Connection ID) are defined. Changes were also madein Section 3 to align with the A1-A4 architecture. The contribution provides definitions of the followinginformation elements used in creating this alignment:• Call Reference• SDU Node ID• SDU ID• A3 Traffic Circuit ID• A3 Traffic Connection ID• Code Channel List.It was accepted with modifications.

TR-45.4.2/96.10.01.16© (M. Dolan, Lucent) proposes the removal of several information elements and messagesdue to either non-use in IS-634 messages or to having been superseded by other elements.

TR-45.4.2/96.10.01.17© (M. Dolan, Lucent) proposes the removal of the Soft Handoff Target Self Drop messageand the enhancement of the Soft Handoff Query and Soft Handoff Query Ack to accomplish the same purpose.

TR-45.4.2/96.10.01.18© (M. Dolan, Lucent) proposes a set of assumptions about the packet mode channel and aseries of work items based upon those assumptions. The work items are needed to complete the packet modechannel work for IS-634-A. It was provided for information and for use in identifying subjects for contributions.

TR-45.4 .2 /96 .10.01.19 (J. Jiang, Nortel) raises a messaging delay issue in Inter-BS soft handoff based upon thecurrent A-Interface Reference Model. It was provided for discussion.

TR-45.4 .2 /96 .10.01.20 (E. Chao and J. Jiang, Nortel) defines support for Asynchronous Data Services (ADS)as defined in TIA/EIA/IS-99 (Data Services Option Standard for Wideband Spread Spectrum Digital CellularSystem), TIA/EIA/IS-130 (800 MHz TDMA Cellular-Radio Interface – Layer-Two Logical Link Control – RadioLink Protocol 1), and IS-135 (800 MHz Cellular Systems TDMA Services for Asynchronous Data and Fax). Keychanges include support for a data link layer to transport mobile data over DS0s (64 kbit/s Channels). Thiscontribution on data services was carried forward. A one day meeting for data was planned (for November 6, 1996) tohandle the following: different air interfaces, IWF and SDU at different locations, hard and soft handoff, service



registration, asynchronous/G3 FAX (circuit oriented), packet data (PPDN), and handoff between circuit mode andpacket mode.

TR-45.4 .2 /96 .10.01.21 (K. Chang and J. Jiang, Nortel) provides Stage 3 contents for A-Interface Support ofNetwork Directed System Selection (NDSS). It was modified, and the revised text will be submitted at nextmeeting.

TR-45.4.2/96.10.03.01© (Motorola) provides TR-45.4.2’s procedural recommendations regarding the establishmentof a priority scheme for the future workplan of TR-45.4.2 (reproduced in Table 4). This was discussed with nochange in plans around IS-634-A (PN-3539).

REPORT OF TR-45.5, WIDEBAND SPREAD SPECTRUM DIGITALTECHNOLOGIES STANDARDS, OCTOBER 14 – 18, 1996, EASTSOUND,

WAThe Chair of TR-45.5 is J. Alphonse (Ameritech Mobile). The standard question about IPR (Intellectual PropertyRights) brought the standard answers from Qualcomm, Ericsson, Lucent Technologies, GTE Mobilnet, OKI Tele-com, Motorola, and Nokia. TR-45.5/96.10.18.11 from Ericsson notes that they hold US patent 5,193,140 byMinde which they believe is essential to IS-127 (Enhanced Variable Rate Codec Speech Service Option 3 forWideband Spectrum Digital Cellular System).

TR-45.5/96.10.14.04 is correspondence from TR-45.3 to the T1P1 with regard to spurious emissions andinterference between stations in close proximity. It was remanded to TR-45.5.3 for information.

TR-45.5/96.10.14.05 is incoming correspondence from TR-45.4 regarding Stage 1 System Selection forPreferred Roaming (SSPR) and Service Programming Lock (SPL) feature descriptions. TR-45.4 has reviewed theseand indicates that while changing the Service Programming Code, the process may be interrupted which could resultin the SPC being inadvertently changed to an unknown SPC. Consequently, mobile manufacturers should considerimplementing the procedure for changing the SPC in a manner that will ensure that the mobile will default to theearlier SPC if the SPC change procedure is interrupted. It provides a review by TR-45.4 of the TR-45.5 featuredescriptions. It was remanded to TR-45.5.1 and TR-45.5.2 for preparation of a suitable response.

TR-45.5/96.10.14.06 is incoming correspondence from the AHAG alerting TR-45.5 to possible securityproblems of SSPR caused by malicious programming of the Negative List or the Preferred-Only indicator. It wasremanded to TR-45.5.1 and TR-45.5.2.

TR-45.5/96.10.14.07© (L. Owens, AHAG, AT&T) is incoming correspondence responding to a TR-45.5 liaison. Itprovides requested definitions of the terms “privacy” (confidentiality of subscriber information) and “security”(protection of service provider resources) for use in TR-45.5 documents. It was remanded to TR-45.5.2.

TR-45.5/96.10.14.08© (L. Owens, AHAG, AT&T) is incoming correspondence responding to a TR-45.5 liaison.The AHAG indicates that signaling message encryption is adequate to protect the SPC from interception over the airinterface. However, AHAG believes that additional means would be required to prevent attacks such as replay andman-in-the-middle. The AHAG also indicates that the risk of signaling when message encryption is not availableonly risks compromising a single phone if due care is taken in the assignment of codes to phones. It was remandedto TR-45.5.1 and TR-45.5.2.

TR-45.5/96.10.14.10© (AirTouch, Ameritech, GTE, US Cellular, 360° Communications, BANM, PrimeCo)proposes changes to the Service Programming Lock (SPL) Stage 1 Requirements. It specifies that mobile stationssupporting SPL shall also support IS-95 (Mobile Station - Base Station Compatibility Standards for Dual-ModeWideband Spread Spectrum Systems) Signaling Message Encryption (SME). It was remanded to TR-45.5.1.

TR-45.5/96.10.14.11© (S. McConoughey, Panasonic) is a report of actions, significant to TR-45.5, that were takenby TR-46 and T1P1 at their meetings during the week of September 30, 1996. The contribution includes a paper byNortel which describes an analysis of the possible interference between PCS 1900 and IS-95 mobile and basestations and notes that a even a single mobile (either PCS 1900 or IS-95) can significantly impact a base stationwhen it is within a few hundred meters. The impact of IS-95 interference on PCS 1900 systems is considerablygreater than the reverse. Collocation of base stations or cell site coordination appear to be the most promisingmeans to address this problem. It was remanded to TR-45.5.3.

The Chair then introduced D. Lee (BellSouth), Chair of a working group in the National Spectrum ManagersAssociation. The association has requested various TIA subcommittees to provide technical data that will enable theassociation to take measures to avoid mutual interference among emitting systems not yet deployed. Also presentfrom NSMA were Mr. Bender of Itron and C. Smith of Western Wireless.

The Chair advised that the publication of two documents, including IS-127 (Enhanced Variable Rate Codec SpeechService Option 3 for Wideband Spectrum Digital Cellular System), was delayed because the formatting (position ofpage numbers, etc.) was not in accordance with new ANSI/TIA requirements. The Chair was to get the changesmade and resubmit the documents. This will delay the actual publication of IS-127 but will have no effect on theadvance copies furnished with the report of the September meeting and also sent directly to Mr. Minami and Dr.Akamine.



FEATURE REQUIREMENTS

The subject of feature requirements, and the Feature Requirements Task Group (TR-45.5.1.4), are taking on muchgreater importance as the end of 1996 approaches. During the last two meetings of the year, TR-45.5.1.4 willformulate its work plan for 1997. The work plan lists candidate features and gives priorities for their beingconsidered in the meetings. The following list contains the features which are being considered for the 1996 workplan at this time:• EVRC (Enhanced Variable Rate Codec)• Hands-Free• 13 kbit/s codec (similar to CDMA PCS codec)• Telephone Devices for the Deaf (TDD) support• Voice-controlled services (speech recognition)• High speed data services (various services are desired by the carriers)• Enhanced roaming display• Smart card• Priority Access and Channel Assignment (PACA) for analog (like for CDMA)

TR-45.5.1 USER NEEDS AND SERVICES

The Chair of TR-45.5.1 is S. Thomas of AirTouch.

TR-45.5.1/96.10.15.08© (P. Brown, TR-45.5.1.2 Chair, GTE) provides a status of the TR-45.5.1.2 review of SPL.TG 2 reviewed the contributions regarding Programming Lock and System Selection for Preferred Roaming. Theirfindings were:

1. SPL should operate no differently over analog channels than digital channels.2. The existing analog OTA procedures are adequate for the transport of the Enhanced Roaming List.

The issues were held open in TR-45.5.1, and the document was remanded to TR-45.5.1.4 to see whether any actionswould be necessary.

TR-45.5.1 held a special meeting to approve a proposal from TR-45.5.1.4 to make several changes to ServiceProgramming Lock Stage 1 for forwarding to TR-45.5:1. Under item 1) in section “Normal Operation with Successful Outcome” (page 3, line 23), the following

requirement was added: Changes to the stored value of the SPC should take place only upon completion of thereprogramming process.

2. The following statement was added to section “Exception Procedures or Unsuccessful Outcome” under“Activation” and “De-Activation” (page 4, lines 13 and 15):

In the event that the SPC re-programming procedure is interrupted, the SPC shall revert to the permanentstored value that was in place prior to the beginning of the procedure.

3. In regard to the concerns about the possible impact of number portability regulations on SPC, TR-45.5 concludedthat no additional requirements were needed. When SPL is active in a mobile station, changing service providersis precluded for that mobile station. In the event that SPC does need to be transferred between service providers,administrative procedures would be required.

These three distinct points were proposed, responding to three contributions addressed in TR-45.5.1.4, and they wereapproved in TR-45.5.1 and later in an interim TR-45.5 plenary session.

TR-45.5.1.1 SPEECH SERVICES

The Chair of TR-45.5.1.1 is J. Gabor of Lucent Technologies.

There was little progress on EVRC (Enhanced Variable Rate Codec) minimum performance specification at thismeeting. The Editor of the minimum performance standard, as well as three other key persons, did not attend themeeting. It was reported off-line that the debugging of the EVRC C code was continuing and should be finished byDecember.

TR-45.5.1.1/96.10.14.03© (J. Ashley, Motorola) is the test plan document to be used by TR-45.5.1.1 to evaluatethe bit-exact codec standard for the EVRC. It serves two functions. First, it represents the test plan which will begiven to Comsat Labs for testing of the bit-exact C code, when that becomes ready for testing. It had already beenapproved previously without a written contribution, since it is merely a subset of the overall EVRC test plan andwas discussed at a previous meeting. Second, it is the text which will be the backbone of the future performance



specification standard, which remained to be written and adopted. It was expected that, at the next meeting, there willbe available an actual version suitable for adoption as baseline text.

It was decided that, at the next meeting, the first item of business of TR-45.5.1.1 will be to examine a contributionexpected from the Editor and, after whatever modification is necessary, propose it to TR-45.5 as baseline text. Aspecial short plenary session of TR-45.5 was scheduled for this purpose. Then TR-45.5.1.1 will reconvene in V&Vmode to attempt to make the document suitable for ballot approval at the next meeting.

FLAWED SPEECH SOURCE FILES

F. Corcoran (Comsat Labs) reported to the Chair that all the speech source files used for MOS (Mean OpinionScore) tests prior to the EVRC (and not including the EVRC) were flawed, in that they were supposed to be flatspeech but were actually only partly flat and partly IRS-filtered. This made all the testing done before the EVRCinexact and not correctable at this time. It could not be told exactly what improper results, if any, were obtainedbecause of this. It does suggest that the EVRC can be claimed to be the first properly tested codec to be used inCDMA.

TR-45.3 SPEECH SERVICES ACTIVITIES

The speech services task group of TR-45.3, as a result of strong carrier inputs, has embarked on a study of thefollowing:• A half-rate codec• A full-rate codec with certain fall-back characteristics (called “multi-rate”)• A codec which will operate at 16 kbit/s indoors, fall back to 8 kbit/s outdoors, and fall back again to 4 kbit/s

when a bad channel is experienced• Trellis-coded modulation

When discussing their own 1997 work plan (see below), TR-45.5.1.1 decided that none of these TR-45.3 workactivities would be appropriate for TR-45.5 because of the different, and less severe, speech problems associated withCDMA as compared with TDMA. That is, different air interfaces require different approaches.

SPEECH SERVICES 1997 WORK PLAN

TR-45.5.1.1 agreed that the following items should be included in the 1997 work plan:• Hands-free• Complete the minimum performance standard for the EVRC• Complete the bit-exact coding for the EVRC• Examine a 13 kbit/s codec to match the one inherited from PCS CDMA• Keep up a “bug-list” on the current EVRC which may lead to a revision of IS-127 (Enhanced Variable Rate

Codec Speech Service Option 3 for Wideband Spectrum Digital Cellular System)

TR-45.5.1.1 also felt that some activity would be necessary in the future on the following, although they were notincluded in the Work Plan as yet:• TDD (Telecommunications Devices for the Deaf) support• Voice-controlled services (speech recognition)

TR-45.5.1.2 ANALOG COMPATIBILITY AND NETWORK INTERCONNECTION

TR-45.5/96.10.18.04 contains the summary report of TR-45.5.1.2.

The proposed Stage 2/3 text for the SPL feature was reviewed. The conclusion was that SPL should operate nodifferently over analog channels than digital channels.

The proposed Stage 2/3 text for SSPR feature was also reviewed. It was felt that existing analog OTA (Over-the-AirActivation) procedures were adequate for the over-the-air transport of roaming list parameters. However, there maybe analog impacts regarding segmentation of the roaming list messages.

Work continued on eliminating discrepancies between SP-3598 (800 MHz Analog Cellular Systems Mobile Station– Base Station Compatibility, TIA/EIA-553-A) and the analog sections of IS-95-A. New technical and editorialchanges were submitted to TR-45.1. An ad hoc group will meet via conference call on October 28, 1996, tocontinue the review and make recommendations, if necessary, on the proposed changes.

A contribution was expected at the next meeting proposing text for the analog sections of IS-95-B.



TR-45.5.1.2/96.10.17.01© (P. Brown, GTE) identifies five outstanding SP-3598 issues in TR-45.1:1. Ericsson contribution re: TR-45.5 edits.2. Authentication changes (2.3.12)3. Abbreviated Alert and Message Waiting OK , Disable DTMF and Page on FOVC .4. Waiting for Order time (5 vs. 10 seconds)5. Location Area processing

TR-45.5.1.2/96.10.17.02© (S. Dennett, Motorola) contains 22 editorial changes to SP-3598 as proposed by TR-45.3 at a recent joint meeting of TR-45.1 and TR-45.3. TR-45.1 had accepted these changes but asked TR-45.5 toreview and comment prior to editor changes.

TR-45.5.1.4 FEATURE REQUIREMENTS

The Chair of TR-45.5.1.4 is S. Thomas of AirTouch.

TR-45.5 .1 .4 /96 .10 .15 .02 (same as TR-45.5/96.10.14.05 ) is incoming correspondence from TR-45.4 withregard to Stage 1 System Selection for Preferred Roaming and Service Programming Lock feature descriptions. Itprovides a review by TR-45.4 of the TR-45.5 feature descriptions. Their first comment noted that an interruption inthe middle of a System Programming Code (SPC) change could leave the mobile with an unknown SPC, thereforerendering it useless. It was agreed that any interruption should result in the mobile reverting to the previouslyauthorized SPC. It was reported from TR-45.5.2 that this was being taken care of in Stages 2 and 3, but thequestion remained as to whether it should be addressed in Stage 1. TR-45.5.1.4 decided to add wording to Stage 1 tothe effect that for abnormal or unsuccessful operation, the mobile defaults to its permanent SPC. This was to berecommended to TR-45.5, in that the Stage 1 document was now at that level. (See TR-45.5.1 above.)

The second comment was a reference to a possible problem when and if number portability becomes implemented(i.e., how would the SPC be transferred from one service provider to another?) Depending upon the interpretation ofnumber portability, the concept could be in contradiction with the concept of programming lock, which is designedto prevent rather than enhance the changeover of the mobile to non-preferred service providers. If, on the other hand,number portability means that a subscriber can keep his number when changing contracts from one provider toanother, then the SPC would probably be set to zero and a new SPC assigned. TR-45.5.1.4 agreed that a responseto TR-45.4, to the effect that this is not a problem, should be the TR-45.5.1.4 recommendation to TR-45.5.2 andTR-45.5. (See TR-45.5.1 above.)

TR-45.5 .1 .4 /96 .10 .15 .03 (same as TR-45.5 /96 . 10 .14 .06 ) is incoming correspondence from the AHAGalerting TR-45.5 to possible security problems of SSPR having to do with malicious programming of the NegativeList or the Preferred-Only list of SSPR Stage 1. The AHAG recommends that the feature include means to preventmalicious programming over-the-air. TR-45.5.1.4 noted that these issues were apparent from the beginning, and theAHAG report merely confirmed TR-45.5.1.4’s fears. TR-45.5.1.4 considered that the issues do not require specialmeasures but that action of some kind would be taken to combat malicious programming. (See TR-45.5.1 above.)

TR-45.5.1.4/96.10.15.04© (L. Owens, AHAG, AT&T) (same as TR-45.5/96.10.14.08©) is incomingcorrespondence from AHAG responding to a TR-45.5 liaison. It provides answers to two questions regarding theadequacy of signaling message encryption. The answers were generally considered ambiguous and related to thecarriers’ concern as to the risks. However, the AHAG did concur that a compromise of the SPC results in thecompromise of only a single phone. TR-45.5.1.4 agreed that this information was useful but it did not change otherdecisions. The document was noted.

TR-45.5.1.4/96.10.15.05© (AirTouch, Ameritech, GTE, US Cellular, 360° Communications, BANM, PrimeCo;same as TR-45.5/96. 10.14.10©) proposes changes to the Service Programming Lock (SPL) Stage 1 Requirementsspecifying that mobile stations supporting SPL shall also support IS-95 Signaling Message Encryption (SME). Itprovides that, if a service provider wishes to invoke signaling message encryption, then the mobile will be properlyequipped. It was agreed to forward the recommended change of Stage 1 to TR-45.5. (See TR-45.5.1 above.)

TR-45.5.1.4/96.10.15.07© (S. Mizikovsky, Lucent) provides analysis of the T1P1 Requirements for the UIM (UserIdentity Module) for Personal Communications Services from the point of view of compatibility and applicability toIS-41 (Cellular Radio Telecommunications Intersystem Operations) services and architecture. It reports that theUIM, as specified, does not work in an IS-41 environment, particularly with regard to security issues. The TR-45.5liaison person to the AHAG (D. Ott, OKI) reported that this was well known to the AHAG. What was needed wasto know whether TR-45.5 had any particular CDMA issues of its own to state. Thus no action was required on thisdocument.



Higher rate services were addressed using TR-45.5 .1 .4 /96 .09 .12 .02 (C. Carey, US West and D.N. Knisely,Lucent) submitted in September. It proposes an updated version of the High Speed Data Service Stage 1 description.It was examined in detail. It lists and describes nine specific areas of use that can benefit from higher speed dataservice:• Database/world wide web• File transfer• Electronic mail• Broadcast data• Video telephony• Program sound• Asynchronous circuit support• Rate adapted data• Group 3 Fax.A number of minor changes were discussed and agreed upon. Since a number of physical layer issues needed to beworked out before this could be final Stage 1, it was agreed that the document would be accepted as a “workingversion of Stage 1 description of high speed data.”

TR-45.5.1.4/96.10.17.02© is a proposed liaison to TR-45.5.3.1 and TR-45.5.1.5 regarding a High Speed Datameeting. It proposes a joint meeting on the subject of high speed data, building on the discussion of the previousday on this subject.

Lucent brought up a problem about 911 service and SSPR. There are situations in which the subscriber is notidentified to the available system and cannot be processed for 911. This could happen in an SSPR environment,which is the first situation in which a mobile may be denied service. It became apparent from the discussion that theindustry had not yet adequately examined the understood requirement that a mobile must be able to make anemergency call under any and all conditions. This issue awaited further contributions and further consideration.

The Enhanced Roaming Display Feature was then considered based upon a contribution from the August meeting,TR-45.5 .1 .4 /96 .08 .22 .01 , incoming correspondence from TR-45.5.2. The issue was about what informationto furnish the mobile of its current roaming status. Some twelve values were recommended, but the issue was heldopen to see if different or more values would be desirable. TR-45.5.2 asked for guidance on this subject. TR-45.5.1.4 had nothing further to offer, but the Chair asked that service providers bring recommendations to the nextmeeting.

The subject of “smart card” based upon an older contribution, TR-45.5.1/96.06.11.03 (Comcast Cellular and USCellular), Smart Card Stage 1 Description (Version 1.1), was discussed. It was decided to consider this as part of the1997 work plan and prioritize it at a future date.

TR-45.5.1.4/96.10.17.03© is a proposed liaison to TR-45.2 requesting that the TR-45.2 WIN Task Group present asummary of their work on Wireless Intelligent Networks (WINs). With minor corrections of the proposed letter, itwas approved.

TR-45.5.1.4/96.10.17.04© is a proposed liaison to TR-45.4 in response to their comments on SSPR and SPL. Itthanks them for their recommendations with regard to service programming lock and advises them of changes TR-45.5 has made to the Stage 1 as a result. It was approved.

TR-45.5.1.4/96.10.17.05© (S. Thomas, TR-45.5.1.4 Chair, AirTouch) proposes development of two new featuresto allow users to restrict the display of calling name and calling number information, Calling Name and CallingIdentity Restriction Features. It advises that the proposal was submitted to TR-45.2.1; it was for information.

TR-45.5 .1 .4 /96 .10 .17 .06 (C. Carey, US West and D.N. Knisely, Lucent) proposes Version 0.09 of the Stage1 Service Description for Data Services - High Speed Data Services. It is an updated version of TR-45 .5 .1 .4 /96 .09 .12 .02 , based upon discussions during this meeting. It was provided for study and preparationfor the next meeting.

TR-45.5.1.4/96.10.17.07© (P. Brown, GTE) requests support of PACA (Priority Access and Channel Assignment)in IS-95 analog mode. It suggests Priority Access and Channel Assignment (PACA) for analog as a candidate forthe 1997 Work Plan. PACA is already a part of the planned IS-95-B for CDMA, but it has advantages for analog inthose geographical areas in which digital is slow to activate. The task group agreed that this should be considered atthe next meeting.

The Chair agreed to bring a draft 1997 work plan to the next meeting.



TR-45.5.1.5 DATA SERVICES

Work continued on PN-3676 (Data Services Standard for Wideband Spread Spectrum Systems). A first draft of theAT command processing chapter was received and reviewed. Several issues were identified and will be reviewedfurther before the next meeting.

It was agreed to freeze the section on asynchronous data and fax call processing.

It was agreed to change the title of PN-3676 (IS-107) to “Data Services Standard for Wideband Spread SpectrumSystems.” An initial draft of the entire document was expected to be ready during the first quarter of 1997.

TR-45.5.1.5/96.10.17.01© (J. Tomcik, Qualcomm) contains Revision 10 of PN-3676.2, Data Standard, RLP(Radio Link Protocol) Section, to be published as TIA/EIA/IS-707.2, dated October 17, 1996. It was reviewed andwas expected to be frozen next month.

TR-45.5.2 S IGNALING PROTOCOLS

IS-95-B

Several contributions submitted by TR-45.5.2.3 for inclusion in PN-3693 (Mobile Station - Base StationCompatibility Standards for Dual-Mode Wideband Spread Spectrum Systems, IS-95-B) were approved.

CNIP (Calling Number Identification Presentation) text changes were approved that allow distinguishable sub-addressing to be sent on the reverse channel as well as the forward channel. Updates for the inclusion of NDSS(Network Directed System Selection) were also approved which add the service redirection message on the forwardtraffic channel and introduce automatic re-origination.

As part of the exercise to merge J-STD-008 (Personal Station-Base Station Compatibility Requirements for 1.8 to2.2 GHz CDMA Personal Communications Systems), signaling message format text was also approved. TR-45.5.2also approved a set of proposed corrections that were submitted by TR-45.5.2.3 last month.

A hard copy of the draft text for PN-3693 was expected from the Editor at the next meeting.

SHORT MESSAGE SERVICES

TR-45.5/96.10.18.08©,Proposed baseline text for TSB-79 (Short Message Services Update, PN-3823) was adoptedby consensus with a recommendation to the Plenary to adopt it as baseline text and send it to V&V. The textconsists of changes previously approved by TR-45.5.2 and two proposed changes submitted by Qualcomm andapproved by TR-45.5.2. It was also approved by TR-45.5.

INTERNATIONALIZATION

Proposed text submitted by TR-45.5.2.3 for inclusion in PN-3693 (IS-95-B) to support country-specific services wasapproved. Correspondence to TR-45.5.1 was also approved to request changes to TSB-58 (Administration ofParameter Assignments) to define the international extended burst type.

A contribution proposing a new information record in the origination and origination continuation messages tosupport sub-address delivery for CNIP was introduced by Qualcomm. It was remanded to TR-45.5.2.3 fordeliberation.

TR-45.5.2.3 CALL PROCESSING, SIGNALING FORMATS AND PROTOCOLS

Work continued on IS-95-B (PN-3693), including merging J-STD-008 into IS-95-A and TSB-74 (Support for 14.4kbit/s Data Rate and PCS Interaction for Wideband Spread Spectrum Cellular Systems) and approving several itemsof proposed text for IS-95-B. IS-95 corrections and updates were still being considered.

Input from TR-45.5.1 on CNAP (Calling Name Presentation) was still outstanding.

TR-45.5.2.3 is working on the IS-683 TSB (OTA) to include SSPR and programming lock; they adopted a startingpoint for baseline text.

S. Mizikovsky (Lucent) was appointed Editor and Chair of an issues ad hoc group. The ad hoc group will provide adraft TSB at the next meeting.



CLOSING TR-45.5 PLENARY SESSION

TR-45.5/96.10.18.02© (TR-45.5.3.1) is proposed outgoing correspondence in response to T1P1 regarding anincrease in PACS (Personal Access Communications System, Licensed Band) spurious emissions. It states that TR-45.5 has asked its membership to determine whether there are realistic co-location scenarios in which spuriousemissions from a PACS RP (Radio Port) would cause a real degradation in the performance of a CDMA base stationreceiver. The document was approved.

TR-45.5/96.10.18.03© (TR-45.5.3.1) is proposed outgoing correspondence in response to TR-46 on PN-3777 (PCSto PCS Interference). It offers a replacement for Figure 3.1.2-2 in PN-3777. It was approved.

TR-45.5/96.10.18.05© (TR-45.5.1) is a proposed liaison to TR-45.2 requesting the TR-45.2 WIN Task Group topresent a summary of their work on WINs. Informally, the presentation was scheduled for the December meetingduring the opening plenary session. It was approved.

TR-45.5/96.10.18.06© (TR-45.5.1) is a proposed liaison to TR-45.4 in response to their comments on SSPR andService Programming Lock. It thanks them for their recommendations with regard to service programming lock andadvises them of changes TR-45.5 has made to the Stage 1 as a result. This turned out to be a subset of, and aduplication of, TR-45.5/96.10.18.10©. This contribution, therefore, was not addressed. TR-45.5/96.10.18.10©(TR-45.5.2) parallels, and in some ways duplicates, the proposed liaison by TR-45.5.1 in TR-45.5/96.10.18.06©.After some minor additions, the TR-45.5.2 proposal was approved.
