RADIO NETWORK PARAMETERS & CELL DESIGN DATA FOR CME 20 R6

3/100 56-FCU 101 201 Uen Rev B 1996-11-07 3(132)

1 IntroductionThe present document explains the Cell Design Data that must be provided foreach cell in a CME 20 R6.0 (and R6.1) system. This data is loaded in thecorresponding BSC by means of a Data Transcript file. A selection of MSCparameters are also included in order to present a more complete picture of theparameters that influence the design of a radio network.

When a new CME 20 system is built or when new cells are added or changedin an existing CME 20 system, the cell planner provides the operator with adocument for each cell containing data for the insertion of the cell in the radionetwork. The data from all such documents is then converted into a datatranscript tape and loaded in the corresponding BSC.

A data transcript tape contains not only CDD information but also other dataneeded for the complete configuration of the BSC and its BTSs. A descriptionof such information is out of the scope of this document.

This document explains what information is contained in the previouslymentioned document which will henceforth be called CDD (Cell Design Data).

In addition to the above mentioned BSC cell parameters, a couple of radiorelated MSC parameters and exchange properties are included in thisdocument. These parameters are included in order to present a more completepicture of the parameters that influence the design and evaluation of a radionetwork.

Note: The MSC parameters are only defined for Ericsson Mobile ServicesSwitching Centers. These parameters may have another name or may not existat all in MSC’s manufacured by others than Ericsson.

This document is valid only for CME 20 R6.0 and R6.1. It will be revised andmodified every time the system incorporates new features.

This document gives references to GSM Recommendations.

This document provides short descriptions of CME 20 R6 parameters. For afull understanding of each of them, it is essential to study the description ofeach particular feature.

The topics where GSM 900 and DCS 1800 differ are indicated.

This document assumes that the reader is acquainted with the channel structurefor GSM and DCS, the TDMA concept and the locating algorithm for CME 20.

1.1 The CDD structure

The parameters in this document are organized according to radio networkfeatures. The aim with this structure is to facilitate a more feature oriented cellplanning and network optimization.

In each radio network feature section, the parameters are grouped into sub-sections defined by the network entity where the parameter is defined. This isdescribed more elaborately in section 1.2.

The CDD is also arranged with a structure that corresponds to the subcellstructure shown in figure 1. Therefore some parameters appear in more thanone part of the CDD.

Figure 1 The subcell structure supported by CME 20 R6.

A subcell is a set of channels that share some specific characteristics. Anoverlaid subcell is defined as a number of traffic channels serving a part of alarger cell. An underlaid subcell is defined as a number of traffic channelsserving the whole cell area.

A cell always has an underlaid (UL) subcell, whereas the overlaid (OL) subcellis optional. A subcell structure exists when there is an overlaid subcelldefined. The notation “cell/subcell data” (see section 1.2) is used in order toclarify that these parameters may be defined per subcell.

Each subcell is divided into channel groups which include a subset of thefrequencies defined for a cell. A channel group can not be shared betweendifferent subcells. One frequency can be defined in only one channel groupwithin the cell.

MSC The parameter is valid for all cells in the MSC.

BSC The parameter is valid for all cells in the BSC.

BSC exchange property The exchange properties are changed by means of aspecial command, but they are essentially the sameas regular parameters.

Cell The parameter is valid for both UL and OL subcell,if there is a subcell structure defined.

Cell/Subcell The parameter may be defined individually for ULand OL subcells, in case there is a subcell structuredefined. Otherwise, they are defined per cell.

Neighbour Cell The parameter need to be defined for internalneighbour cells.

External Cells See section 3.2.3

10(132) 3/100 56-FCU 101 201 Uen Rev B 1996-11-07

Comments: Base Station output power in dBm for the BCCH RF channelnumber.

The BTS can transmit with different power levels on thefrequency that carries the BCCH and on the frequencies that donot carry it. The power is specified at the Power Amplifier (PA),output, i.e. immediately after the transmitter unit and before thecombiner.

For RBS 200 the following is valid:

GSM 900: 31 to 47 dBm, odd values only.DCS 1800: 33 to 45 dBm, odd values only.


GSM 900 (TRU: KRC 131 47/01):35 to 43 dBm, odd values only.

GSM 900 (TRU: KRC 131 47/03):35 to 47 dBm, odd values only

DCS 1800: 33 to 45 dBm, odd values only.

If one or more GSM TRU type KRC 131 47/01 is used withinone site the maximum output power for that site shall be limitedto 43 dBm. To ensure that, the parameter MPWR (see page 113)shall be set to 43 dBm for all TXs on that site.

CELL

Thebest choice for this character is a number (1,2,3...) or a letter(A,B,C...) identifying the antenna pointing direction of the cell.The 0 (zero) degrees true north direction can be taken as areference. The cell whose antenna direction is closest to thereference direction when counting clockwise, should be assignedletter A (or number 1).


3/100 56-FCU 101 201 Uen Rev B 1996-11-07 11(132)

CGI

Type: MCC-MNC-LAC-CI.

Range: MCC: 3 digits (Mobile Country Code).MNC: 2 digits (Mobile Network Code).LAC: 1 to 65535 (Location Area Code).CI: 0 to 65535 (Cell Identity).

Unit: –

Default: –

Command: RLDEC.

Comments: CGI (Cell Global Identity) is the global identity of the cell in thewhole system. It is composed of four different parameters:

MCC, Mobile Country Code,

MNC, Mobile Network Code identifying the PLMN (Public Land Mobile Network, i.e. the operator),

LAC, Location Area Code,

CI, Cell Identity within the location area.

CGI is sent to the mobile station (MS) as a part of the systeminformation message (GSM Rec. 04.08). The combination MCC-MNC-LAC is also known as the location area identity (LAI).

BSIC

Type: NCC-BCC.

Range: NCC: 0 to 7 (Network colour code).BCC: 0 to 7 (Base station Colour Code).

Unit: –

Default: –

Command: RLDEC.

Comments: BSIC (Base Station Identity Code) is composed of two entities:

NCC Network Colour Code.

BCC Base station Colour Code,

BSIC is defined on a per cell basis and it is sent on the logicalsynchronisation channel (SCH) on the BCCH frequency.

GSM 03.03, Annex A, assigns one NCC value "n" to eachEuropean country "to ensure that the same NCC is not used inthe adjacent PLMNs". A second operator in a given countrywould use the NCC value "n+4".


12(132) 3/100 56-FCU 101 201 Uen Rev B 1996-11-07

When an MS reports the results of the measurements made onthe serving cell and the neighbouring cells, it indicates(GSM 04.08, section 9.1.20):

The measured levels on the serving cell.

The measured levels, the BSIC and the BCCH frequency of theneighbouring cells.

Only measurements from cells with allowed NCC are reported(see section 3.3.4).

The colour code NCC is then used to discriminate cells that usethe same frequency. Though mainly intended for the purpose ofdifferentiating PLMNs, it also serves to distinguish cells withinone PLMN that use the same frequency provided they have beenassigned different NCC. If there are two operators in a country,they can use more than two PLMN colour codes each one,provided that in border areas only the values "n" and "n+4" areused.

What is stated here should be considered as general guidelines.Of course any type of NCC assignment must be decided byagreements between operators and countries.

Regarding the protection against co-channel interference, the MSreports the BCC value so that the BSC can distinguish amongdifferent cells transmitting on the same frequency. For thispurpose the BCC must be allocated as wisely as possible. Iffrequency reuse clusters are used then

it is recommended that all BTSs in a given cluster use the sameBCC. In this way the reuse distance of a certain BCC willhopefully be maximised

Note that only 8 different values (BCC: 0 to 7) are used for thepurpose of recognising co-channel interference.


3/100 56-FCU 101 201 Uen Rev B 1996-11-07 13(132)

BCCHNO

Type: Numeral.

Range: 1 to 124 (GSM).512 to 885 (DCS 1800).

Unit: –

Default: –

Command: RLDEC.

Comments: Absolute RF channel number for BCCH.

Absolute RF channel number already defined for a dedicatedchannel can not be used.

The frequency carrying the BCCH (Broadcast Control Channel)in a cell is defined by the Absolute Radio Frequency ChannelNumber, ARFCN, with the parameter BCCHNO. The definedARFCN must be unique within the cell.

According to the GSM recommendations the channels arenumbered as follows:

fl(n) = 890.2 + 0.2*(n−1) in MHz, where n (Absolute RadioFrequency Channel Number, ARFCN) goes from 1 to 124 and fl

is a frequency in the lower band, BTS receiver.

fu(n) = fl(n) + 45 in MHz, where n goes from 1 to 124 and fu is afrequency in the upper band, BTS transmitter.

According to the DCS recommendations the channels arenumbered as follows:

fl(n) = 1710.2 + 0.2*(n−512) in MHz, where n (Absolute RadioFrequency Channel Number, ARFCN) goes from 512 to 885 andfl is a frequency in the lower band, BTS receiver.

fu(n) = fl(n) + 95 in MHz, where n goes from 512 to 885 and fu isa frequency in the upper band, BTS transmitter.

BCCHTYPE

Type: String.

Range: COMB, COMBC, NCOMB.

Unit: –

Default: NCOMB.

Command: RLDEC.


14(132) 3/100 56-FCU 101 201 Uen Rev B 1996-11-07

Comments: Type of BCCH.

COMB indicates that the cell has a combined BCCH andSDCCH/4 (see section 3.1.5).

COMBC indicates that the cell has a combined BCCH andSDCCH/4 with a CBCH subchannel.

NCOMB indicates that the cell does not have any type ofcombined BCCH and SDCCH/4.

The BCCH is always allocated to time slot 0 (TS0) in thedefined ARFCN.

The CBCH is used for transmission of the messages when thefunction Short Messages Service Cell Broadcast (SMSCB) isactivated in the cell. SMSCB enables the operator to submitshort messages for broadcasting to a specific area within thePLMN.

AGBLK

Type: Numeral.

Range: 0 to 7 if non-combined BCCH is used.0 to 2 if combined BCCH and SDCCH/4 is used.

Unit: –

Default: 1

Command: RLDEC.

Comments: Number of reserved access grant blocks.

Number of CCCH blocks reserved for the access grant channel.The remaining CCCH blocks are used for the paging channel.

In each downlink non-combined SDCCH 51 frames multiframethere are 9 different CCCH blocks and in the combinedBCCH/SDCCH there are 3 different blocks. They can be usedto:

• Send paging messages, i.e. used as a Paging Channel.

• Send access granted messages, i.e. used as an Access GrantChannel.

After an MS tunes to the BCCH/CCCH channel and decodes theSystem Information, it performs an evaluation that, taking intoaccount the MS's own IMSI (International Mobile StationIdentity) number, determines to which particular CCCH blocks inthe physical channel it should listen (GSM 05.02). Every CCCHin the physical channel (Paging Subchannel) sends pagingmessages to a certain group of MSs that are called it's paginggroup. The reason for the existence of such paging groups is that


3/100 56-FCU 101 201 Uen Rev B 1996-11-07 15(132)

the MSs can save batteries because it only needs to listen to itsown Paging Subchannel messages.

The physical channel (Paging Subchannel) sends pagingmessages to a certain group of MSs. As mentioned before thesevery same CCCH blocks are also used to send Access Grantedmessages to the MSs, i.e. to answer a Random Access messagethat an MS wanting to access the system has sent to the system.

The structure of the BCCH regarding Paging messages andAccess Granted messages can be controlled by the twoparameters AGBLK and MFRMS .

AGBLK tells how many of the CCCH blocks that should bereserved for the Access Granted messages. In the CME 20system Access Granted messages are given priority over Pagingmessages. Together with MFRMS , AGBLK decides how manypaging groups there will be.

With a non-combined BCCH and AGBLK = 1, there are 8CCCH blocks in each multiframe. This means that it is possibleto have 16 to 72 different Paging Subchannels, i.e. PagingGroups. (Since MFRMS can take values between 2 and 9.)

With a combined BCCH/SDCCH and AGBLK = 1, there are 2CCCH blocks in each multiframe. In this case it is possible tohave 4 to 18 different Paging Groups.

Note 1:AGBLK must not be 0 when SI 7 and 8 have to be sent or whenshort message service cell broadcast (SMSCB) is in use on a cellnot using combined BCCH and SDCCH/4 (GSM 05.02).

Note 2:Only AGBLK = 0 and 1 is supported by the RBS 200 and RBS2000 series BTS.

MFRMS

Type: Numeral.

Range: 2 to 9.

Unit: CCCH multiframes.

Default: 2.

Command: RLDEC.

Comments: Multiframes period. Defines period of transmission for PAGINGREQUEST messages to the same paging subgroup.

Together with AGBLK , MFRMS determines the number ofpaging groups.


16(132) 3/100 56-FCU 101 201 Uen Rev B 1996-11-07

MFRMS is also used by the MS to determine downlinksignalling failure in idle mode (GSM 05.08). The downlinksignalling failure criterion is based on the downlink signallingfailure counter DSC. When the MS camps on a cell, DSC shallbe initialized to a value equal to the nearest integer to 90/Nwhere N is the MFRMS parameter for that cell. Thereafter,whenever the MS attempts to decode a message in its pagingsubchannel; if a message is successfully decoded DSC isincreased by 1, (however never beyond the nearest integer to90/N), otherwise DSC is decreased by 4. When DSC reaches 0,a downlink signalling failure shall be declared. A downlinksignalling failure shall result in cell reselection.

MFRMS is also used by the MS to control monitoring ofreceived BCCH carrier level (GSM 05.08). Whilst in idle modean MS shall continue to monitor all BCCH carriers as indicatedin the BCCH allocation list (BA list). A running average ofreceived level in the preceeding 5 to

Max{5, ((5*N+6) div 7)*MFRMS /4}

seconds shall be maintained for each carrier in the BCCHallocation. N is the number of non-serving cell BCCH carriers inBA.

FNOFFSET

Type: Numeral.

Range: 0 to 1325.

Unit: TDMA frames.

Default: 0.

Command: RLDEC.

Comments: Frame Number Offset.

Indicates the time difference from the FN generator in the BTS.

To prevent that all cells on a site send BCCH channels at thesame time it is possible to define a deviation with respect to theFN generator called FNOFFSET. By using FNOFFSET on atwo or three sector site the time for decoding BSIC can bereduced.

Note:The RBS2000 and RBS200 only supports the range 0 to 1023.

Default: 1.

Command: RLCCC.

Comments: Required number of SDCCH/8.

Call set up, location updating and SMS are using the SDCCHchannel. The system supports four types of combination forSDCCH channels (see also 3.1.2):

Channel combination SDCCH/4, i.e. time slot 0 on the BCCHcarrier contains 4 SDCCH. The remaining capacity is used bythe BCCH and CCCH. (BCCHTYPE = COMB).

Channel combination SDCCH/4 including a CBCH subchannel,i.e. whenever there are short messages to be broadcast in theShort Message Service Cell Broadcast (SMSCB) they arebroadcast in the same physical channel as the SDCCH. TheCBCH replaces SDCCH number 2, i.e. only 3 MSs can getdedicated channels at the same time if a CBCH is defined in thecombined SDCCH/BCCH. (BCCHTYPE = COMBC).

Channel combination SDCCH/8, i.e. each physical channelconsists of 8 SDCCH channels, i.e. 8 MSs can get dedicatedchannels at the same time. (BCCHTYPE = NCOMB, CBCH =NO).

Channel combination SDCCH/8 including a CBCH subchannel.The CBCH replaces SDCCH number 2 in one of the SDCCH/8,i.e. only 7 MSs can get dedicated channels at the same time if aCBCH is defined. (BCCHTYPE = NCOMB, CBCH =YES).

Up to 16 SDCCH/8 can be specified per cell. The number ofSDCCH/8 can not be more than the number of specifiedfrequencies within the cell or Channel Group.

Note that the SDCCH/4 and its CBCH are specified togetherwith the BCCH (see section 3.1.2).

TN

Type: Numeral.

Range: 0 to 3 (normal cell).0, 2 (extended range cell).

Unit: –

CBCH

Type: String.

Range: YES, NO.

Unit: –

Default: NO.

Command: RLCCC.

Comments: Cell broadcast channel. CBCH must not be defined for an OLsubcell.

YES CBCH shall be included in one of the SDCCH/8 for the cell or channel group.

NO No SDCCH/8 for the cell or channel group shall include CBCH.

Example:BCCHNO: 75BCCHTYPE : NCOMBCHGR: 0HOP: OFFDCHNO: 75 & 78 & 81 & 84SDCCH: 2TN: 1CBCH: YES

The preceding choice of parameters says that:

• The carrier number 75, that corresponds to 905 MHzaccording to the GSM definition of frequencies in the BTSTX band, is carrying the non combined broadcast channelBCCH in timeslot number 0.

• The basic physical channels, BPCs in the channel group,CHGR:0 are non hopping.

• The CHGR:0 contains the ARFCN 75, 78, 81 and 84.

• In two of the carriers 75, 78, 81, or 84, an SDCCH/8 islocated on timeslot number 1, and the remaining timeslots inthose particular carriers are carrying traffic channels, TCHs.

• One of the SDCCH/8 referred to in d includes a CBCH.

• The other two carriers, i.e. those not referred to above, arecarrying traffic channels, TCHs, in all remaining timeslots.

With this configuration a cell has one channel group with 4frequencies with 32 non hopping BPCs, 1 BCCH, 2 SDCCH withone CBCH, and 29 TCHs.

The ampersand (&) is suggested as a separator betweennumbers. This is in accordance with the notation used in BSCcommands.

In CME 20 the MS power can be controlled by the parameterCCHPWR, which indicates the maximum transmitter power thatthe MS is allowed to use when performing an access to thesystem (GSM 03.22).

Whilst in idle mode, the MS continuously confirms that it haschosen the most appropriate cell by calculating the quantity C1from the received signal level rxlev:

C1 = (rxlev − ACCMIN ) − max (CCHPWR − P, 0)

The MS camps on the cell providing the highest positive C1.

The condition states that an MS must measure a signal strengthhigher than ACCMIN from a cell to be able to access the systemvia this cell.

In addition, if the MS maximum possible output power, P, islower than CCHPWR then the requirement on the signal strengthincreases by the difference between P and CCHPWR. Thismeans that if the MS cannot reach the maximum output powerthen the requirement on the signal strength in the downlink is


32(132) 3/100 56-FCU 101 201 Uen Rev B 1996-11-07

harder. Probably the measured cell is not designed for MSs of itsclass.

CCHPWR

Type: Numeral.

Range: 13 to 43 in steps of 2 (GSM). 4 to 30 in steps of 2 (DCS 1800).

Default: –

Command: RLSSC.

Comments: Maximum transceiver power level an MS may use whenaccessing on a control channel.

CRH

Type: Numeral.

Range: 0 to 14 in steps of 2.

Unit: dB.

Default: 4.

Command: RLSSC.

Comments: Cell Reselection Hysteresis. Receiving signal strength (rxlev)hysteresis for required cell re-selection over location areaborder.

When the MS is in idle mode it performs an algorithm for cellreselection. It measures continuously the signal strength of thesurrounding cells and selects the carrier that fulfils all of thefollowing criteria:

• Is a BCCH carrier.

• Is part of the selected PLMN, defined by MCC-MNC.

• Is not barred.

• Has the highest positive C1 parameter (phase 1 MSs) asdescribed in GSM 05.08. Phase 2 MSs select a cell accordingto the C2 criterion.

The C1 criterion uses a hysteresis in the case that cells indifferent location areas are compared, i.e. when the required cellselection crosses a location area border. This hysteresis is calledCRH and must be defined for all cells in the system(GSM 03.22).

NO The cell is not barred for access.YES The cell is barred for access.

It is possible to use CB to bar a cell (GSM 03.22 and 05.08).When a cell is barred it is ignored by MSs in idle mode but anactive MS can perform handover to it.

CBQ

Type: String.

Range: HIGH, LOW.

Unit: –

Default: HIGH.

Command: RLSBC.

Comments: Cell Bar Qualify.

The interpretation of CB and CBQ varies depending on whetherthe MS is a phase 1 MS or a phase 2 MS. For phase 2 MS thebehaviour is also different in cell selection from that in cellreselection.

Unit: –

Default: 50.

Command: RLSBC.

Comments: TX-integer.

Defines the number of timeslots over which the MS may spreadtransmission when accessing the system.

When the MS accesses the system it can spread the transmissionover a certain number of timeslots. The parameter TX that theMS receives as a part of the system information message(GSM 04.08, section 10.5.2.29) is used to calculate the timeinterval between successive transmissions.

The MS sends maximum MAXRET +1 Channel Requestmessages on the RACH to the BTS in a way such that(GSM 04.08, section 3.3.1.2):

• the number of slots belonging to the mobile station's RACHbetween initiation of the immediate assignment procedure andthe first Channel Request message (excluding the slotcontaining the message itself) is a value drawn randomly for

CRO

Type: Numeral.

Range: 0 to 63.

Unit: dB.

Default: 0.

Command: RLSBC.

Comments: Cell Reselection Offset.

Defines an offset to encourage or discourage MSs to select thecell while it is camping on another cell, i.e. perform a cellreselection.

0 0 dB1 2 dB···63 126 dB.

In order to optimise cell reselection, the additional cellreselection parameters CRO, TO, and PT are broadcast on theBCCH of each cell. The cell reselection process employs aquantity C2 which depends on these parameters (GSM 03.22).

The reselection quantity C2 is defined as:

C2 = C1 + CRO − TO * H(PT − T) for PT ≠ 31C2 = C1 − CRO for PT = 31


3/100 56-FCU 101 201 Uen Rev B 1996-11-07 39(132)

where

H(x) = 0 for x < 0= 1 for x ≥ 0

T is the timer, started from zero at the point at which the cell wasplaced by the MS on the list of strongest carriers. T is reset tozero whenever the cell is no longer on the list of strongestcarriers. This will tend to prevent fast moving MSs fromselecting the cell (GSM 03.22).

CRO applies an offset to the C2 reselection criterion for the cell.

TO applies a negative offset to C2 for the duration of PT afterthe timer has started for the cell.

PT is the duration for which TO applies. The value 31 of thePT parameter is reserved to change the sign of CRO and thevalue of TO is ignored as indicated by the equation defining C2.

These parameters are used to ensure that the MS is camped onthe cell with which it has the probability of successfulcommunication on uplink and downlink (GSM 05.08).

TO

Type: Numeral.

Range: 0 to 7.

Unit: dB.

Default: 0.

Command: RLSBC.

Comments: Temporary Offset.

Defines a negative offset applied to CRO.

Unit: Seconds.

Default: 0.

Command: RLSBC.

Comments: Penalty Time.

Defines duration for which TO is applied.

0 20 seconds1 40 seconds···31 620 seconds.

The value 31 indicates that the cell reselection offset is negativeand that the temporary offset is ignored.

The cause value is interpreted by the target BSC as “urgencyhandover”. Both TA urgency as well as bad quality urgency canbe recognised. The target BSC carries out the punishment of thecell in the old BSC that was abandoned. However, it uses thepenalty parameter value and penalty time of the new cell. Thisaction can only be performed if the receiving BSC is ofCME 20 R5 status.

3.7 Dynamic BTS power control

The BTS power level can be dynamically controlled during a connection. Thepower control strategy is towards a desired signal strength value received in theMS.

The BSC calculates the new BTS power level by using the data measured bythe MS, i.e. the signal strength and the quality on the downlink TCH carriers
