2.2 Group Mission

This forum comprise representatives of all European railways actively implementing GSM-R or close to start the implementation process and having signed the EIRENE MoU, and majorly has UIC GSM-R activities coordinating role, taking or endorsing decisions.

It is an experience sharing platform, key for members advancement with theirs projects.


ERIG is overseeing the activities of the entire constituent working groups in the field of ERTMS/GSM-R projects/activities (see 1.2).

ERIG is kept informed of progress with implementation and lessons learned in this process, as well as on upcoming standards, applications and technical progress.

The forum gives formal acceptance to Change Requests created by FG, OG and IG (working groups which activity is detailed later on in this document) and therefore supports new versions of specifications for the UIC (EIRENE & MORANE). It also approves the creation of ad-hoc-groups and is responsible for acceptance of the results presented. It technically pre-approves related MoU’s (any UIC new MoU is validated by the UIC General Assembly)

ERIG also has responsibility for pre-approving UIC projects or activities, and further on supports the project or activity approval in the UIC Rail System Forum.

ERIG invites also in the regular meetings ERA (with the observer status), CER, EIM representatives and the GSM-R Industry Group Speaker. The ERIG meeting is hosted by an UIC member, or by UIC itself.

Suppliers are also invited, presenting to the community their latest developments.

2.3 Meeting Reports

It was agreed with the ERIG members that it would be relevant to decrease the ERIG meetings from 4 to 3 meetings in 2011.

Three ERIG meetings took place as planned during 2011:

• ERIG #48 (16 to 17 of March in Warsawa, Poland)

• ERIG #49 (29 to 30 of June in Glasgow, UK)

• ERIG #50 (29 to 30 of November in Vienna, Austria)

2.4 Deliverables

The meeting reports and other related documents are available for members on the UIC Extranet.

• ERIG #48 – documents erig3309 to erig3334 ; in addition with documents coming from the GSM-R Industry Group, Nokia Siemens Networks, Kapsch Carrier Comm, and EIM.

• ERIG #49 – documents erig3335 to erig3362

• ERIG #50 – documents erig3363 to erig3393 ; in addition, information was posted on:

o EIRENE New Baseline Documents (including ERA GSM-R Baseline)

o GPRS for ETCS OBB-UIC Tests Report

o FTA Shunting Demonstration

o ERA GSMR Comference

o ETSI Next Generation 2011 Conference

o KCC & Frequenctis presentations


2.5 Future Plans

ERIG will continue its task; the digital radio system is now reaching operational maturity and with proven interoperability. The system must constantly develop, improved features are needed to reach the very stringent quality of service, to improve operations, while preserving interoperability and protecting investments.

For all these reasons coordination is needed.

ERIG will also coordinate and provide expertise based on existing experience on the issue of Future Railway Telecomunication Systems, needed when GSM will reach its end of life.

3 ERIG meetings are planned in 2012, ito be held in Portugal, Slovenia and Romania.

Coordinated continous effort is needed for tackling the upcoming issues, e.g.:

o Interferences coming from Public Operators,

o Oversee the CCM process

o Voice and Data Quality of Service

o eREC,

o Packet Switched (GPRS) for ETCS,

o Future Railway Telecommunication Systems and smooth switch over

o Certification & Assesment Test Cases

o Covering specifications Gaps

o Applications developments with the guaranteed operations support

3 GSM-R – UIC European related activities

GSM-R Change Control Management Process/EIRENE new Baseline/Support for European Activities/GPRS for E TCS

3.1 GSM-R Change Control Management Process

EIRENE and MORANE specifications are regularly updated when errors are spotted, gaps

are to be filled, or technological progress is to be introduced.

The GSM-R CCM process is posted below.

The GSM-R Pre Qualification Group decides (as until now) for accepting issues to be sent in

the CCM Process, and supplementary on the issue character – touching interoperability or

not. The relevant requirements for interoperability are then sent in the ERA CCM Process,

while the others are treated by UIC.

As technical body, UIC is treating the interoperability issues within the ERA CCM Process,

on ERA demand, and by respecting the ERA ERTMS/GSM-R CCM process rules. The two

processes are linked and synchronized.


3.2 New EIRENE Baselines

UIC and ERA agreed on a MoU on GSM-R , signed in October 2010, based on which work

was started to clarify in the specifications the relevant requirements for the Interoperability in

the EIRENE specifications and in a step 2 in the MORANE ones.

Following that, after 1 ½ years of work result was reached. New EIRENE specifications were released - EIRENE FRS 7.3.0 and SRS 15.3.0; these specifications were approved on 29 of

March 2012 to be recommended by ERA to replace FRS 7/SRS 15 in the CCS TSI.

These new specifications contain the EIRENE 7/15, 7.1/15.1, plus the CR’s O-9171 v2.1 (on

EDOR SRS) and O-9170 v1.1 (SRS references revision); they will replace 7/15 and

7.1/15.1, and what is considerd to be part of the ERA GSM-R Baselines v0r3 – a set pf

requirements that are considered to be relevant for interoperability in Europe, and for which

the ERA CCM process will be further on applied (see point 3.1).

Within these specifications, only the requirements marked with (MI) are considered to be

relevant for interoperability.

It is very important for out of Europe implementers to understand that the split in Manadatory

for interoperability (MI) and Mandatory for the System (M) in the EIRENE specifications

concerns strictly Europe , and as expressed in the categories definitions MI and M

requirements must be implemented in order to develop a viable working system.

3.2.1 Next Baselines Plans

ERA expressed the opinion that in a second step – after identifying and validating the new EIRENE specifications, and after releasing the next baseline (EIRENE FRS 8.0.0 & SRS 16.0.0) - to freeze for a while the (MI) functionalities, for system stability.

Under these circumstances, a large discussion forum was launched by UIC, to make sure that all clarifications or missing featuresshall be made available at that moment.

The candidate’s features were therefore analyzed, selected and ranked, then accepted by FG/OG/GSM-R IG and the Sector Organizations CER/EIM, and this request was presented to ERA end 2011.

The list and its ranking, as well as the ranking procedure is presented below:

ITEM Priority

3.3 Support for European Activities

UIC is highly involved in European activities related to ERTMS/GSM-R, participating to

several activities.

3.3.1 CER CCS Support Group

CER CCS support group is working based on one or two day’s meetings, 9 time a Year.

UIC participates for different CCS subjects, and regularly for GSM-R issues. UIC role is to offer in its technical body qualiy support for the management of Change proposal to ERTMS/GSM-R - analysis and evaluation of the technical and operational viability of proposals selected by CER for further development, to an extent sufficient to enable CER members to make a decision upon whether to adopt the proposal. UIC offers technical support needed for the CER decisions.

3.3.2 ERA Control Group ERA ERTMS Control Group is running the ERTMS ETCS a nd GSM-R CCM process. The Control Group must ensure the steering of the ERTMS activities, identifying the most effective actions to deal with the outstanding issues in coherence with the overall system planning, resources and priorities. UIC regurlary participates in this activity, throug h the GSM-R Project Manager, representing the GSM-R Technical Body.

The ERA CG meets arrround 10 times /Year.

3.3.3 ERTMS MoU Steering Committee

The ERTMS MoU Steering Committee started its work after 2007 ERTMS MoU, being

composed by representatives of all relevant actors in the ERTMS field (EC, ERA, CER, EIM,

UNISIG, GSM-R IG, UIC, Railways).

M Karel Vinck, ERTMS European Coordinator, and M Christian Faure, representing DG

MOVE, chair the group. The group meets every 2 months.

3.3.4 ERA GSM-R Conference

ERA disseminates its ERTMS activities in yearly conferences.

UIC supports directly ERA for this activity, in the scientific committee, responsible for

preparing this Conference, and with speakers during this Conference. The last one took

place in October 2011.


3.3.5 GSM-R Industry Group

The majority of GSM-R suppliers for networks, mobiles and dispatcher systems are gathered

together and represented in the GSM-R Industry Group.

This group is part of the GSM-R CCM process, as well as a UIC partener, in many related

domains. The GSM-R IG representing is participating to the UIC ERTMS Conference

scientific committee.

UIC participates to these meetings, through the GSM-R Project manager and the Operatots

Group Chairman; 4 meetings/year, 2 days meeting – travel included.

3.4 GPRS for ETCS

GSM-R is the today certified digital mobile transmission system. For historical reasons,

GSM-R uses the packet switched transmission mode for carrying the ETCS data.

In order to solution the “bottle neck” provoqued by the lack of GSM-R frequencies in big

hubs, as well as to assure the ETCS future proof, it is wished to migrate the ETCS data

transmission to packet switched technologies.

As the tests carried out must be credible, they must be performed in railway environment, in

live networks, and the only packet switched technology available is GPRS, and maybe in

close future EDGE.

It is to be remembered that GPRS for ETCS opens the way for Packet Switch technologies

(IP) to carry ETCS data in a reliable way; the QoS requirements specification will be crucial

for the future.

In 2010, a Test campaign was organized in Austria, together with OBB, Kapsch Carrier

Comm, Comtest Wireless. The Test Report was circulated end November 2011. The results

generally confirms the previous tests conclusions

Meantime, EC have made a call for projects, with partial TEN-T funding (50%). UIC applied

as part of the “GPRS for ETCS” project, for:

• Producing the test specifications, test reports, specifications

• Optimizing the radio link, in lab and tests campaigns, programmed to take

place in France, UK and Denmark - preparing the ETCS prototypes testing,

via GPRS for ETCS Engineering guidelines


UIC Budget is 492.000 Euro (divided on 2012, 2013 and 2014) financed 50% by UIC

246.000 Euros and 50% the TEN T Agency – 246.000 Euros.

The confirmation arrived from the EC, with a 30% reduced budget. UIC started the work; an

RFI is under preparationg for contracting the measurement tool, first meetings within SNCF

and ERTMS UG started, test concept prepared for discussions.

3.5 UIC related activities

3.5.1 UIC ERTMS Training

UIC performes since a number of years an ERTMS training, where ETCS and GSM-R is presented in detail, by relevant speakers, and country cases are presented, in interaction with around 80-100 training attendees.

In 2011, this training took place as scheduled, with a one day session for GSM-R.

3.5.2 UIC Extranet

UIC organizes the documents storage and exchange via a specialized platform, the UIC Extranet. The exiting platform, outdated, was replaced with a new modern one.

End 2011, the GSM-R & Telecom related content was transferred in the new platform, with a revision of working groups, members, access, allowance, etc.

3.5.3 UIC Non-European activities

As GSM-R is implemented also outside Europe, and as the CBTCS systems are discussed

all over the world, activities are supported by UIC in this domain, especially related to the

UIC Asia.

After a mission performed in Australia in 2010, and the specific support for the UIC Global

Signalling that took place in 2010 in Tokyo, several discussions that took place in UIC Asia

concluded the feasibility of a project on this topic that will be performed in 2012, and will

most likely consists in organizing a UIC Conference on this topic that will be hosted by one

of the UIC Asian members (Indian Railways).

Another action was the support accorded for the IEC work item: “Railway applications – A

procedure to determine the performance requirements for radio system applied to radio-

based train control systems”.

4.2 Group Mission

The GSM-R Change Request Process (CR) is scaled over different phases. The first step is the evaluation of the so called Implementation Report (IR), in which every editorial error, implementation issue, malfunction or gap in the specification, all related to the EIRENE specifications, is reported.

Such a report is accepted from any source, provided that it is reported in a uniformized way, based on a template which can be found at following public available web link:

http://www.uic.org/spip.php?article676

The group is responsible for the decision on the IR on whether it shall be sent in the the GSM-R Change Control Management process. This decision takes into account the need for a new feature, and what this new feature implies, as well as the financial implications and the migration plan.

If the IR is considered relevant, it shall be sent into UIC CCM process except if the issue is considered to be relevant for interoperability, case in which it will be sent into the ERA CCM process.

The group is formed from representatives coming from CER, EIM and UIC, with the participation of ERA representatives, as observers.

For more details, please see 3.1

6.2 Group Mission

The task of the Operators Group is to maintain the EIRENE SRS and relevant technical documentation. The OG also creates CR’s as required, and reviews those – mainly based on functional requirements – received from the FG. The group deals with I,O,M arequirements and the MI requirements at technical level.

The CR’s describe technical solutions and take also into account results of technical expertise from the GSM-R Industry group and from other experts.

The OG determines whether Reports need to be forwarded to the GSM-R Industry Group for further technical assistance.

6.3 Meeting Reports

Operators Group held 4 meetings (OG#42 to OG#45), including additional plenary meetings between FG and OG which took place along 2011.


Major Results: • Creation of the Change Requests necessary for the update of SRS. This update

included the review of the system requirements necessary to successive working versions of Baseline 0. This review included ERA and the Sector inputs


corresponding to the former “Mandatory Requirements” split in “Mandatory for Interoperability” and “Mandatory for the System” operation.

• Review of SRS and handling of Change Requests: 36 CRs for FRS & SRS were accepted for EFRS7.1 & ESRS15.1;

7 ETSI Rail Telecom (TC-RT)

7.1 Group Mission

This group forms the railways users and suppliers interface to ETSI.

The group is set up with representatives of the O.G. and includes members of the GSM-R Industry. The main task of this group is the investigation of existing GSM standards and the creation of CR’s to these standards. Liaison statements to 3GPP and other standardization bodies guarantee that the requirements and restrictions of the railways are taken into account.


This year TC-RT was very active addressing new fields very important for Railways, such as the frequency issues, alignment of the specifications with release 99 and the evolution toward IP. It published several Technical Specifications (TS) which are listed below:

• TS 103 169 v1.1.1 ASCI Options for interoperability

• TS 103 389 v1.1.1 Usage of SIP on the NSS to FTS interface

• TS 103 066 v1.1.1 Rel-4 Core Network requirements

8.2 Group Mission

The Frequency management group is taking care for all issues in the frequency domain related railways adio matters.


During the last two years 6 meetings were held at UIC in Paris. Main subjects discussed: Interferences into GSM-R systems (mainly coming from Public Operators), solutions.

Interferences to GSM-R – mainly coming from Public Operators

GSM-R was designed late ninethies to coexist with public mobile networks in a GSM environment. Lately, broadband technologies started to be more and more encouraged (which is a natural and welcomed process) and started to be promoted in the GSM 900 MHz bandwidth.


Compatibility studies (e.g. ECC Report 96) have stated a possible coexistence between new technologies coming up and the existing one, GSM-R included, report which was contested by UIC due to unapropiate simulation method.

Therefore, even if the newcomer technologies must – by European law – make sure that they does not provoque “harmfull interferences” to existing systems – GSM-R included, interferences cases with different causes started to appear and the trend is growing.

End 2010 there was no recognition on of this critical issue on “upper levels”.

Strong actions were started within UIC, at demand of its members:

• A GSM-R Interferences technical Report was produced (O-8700 v1.0), and public distributed, to have a basic refernecs for discussions at all levels.

• A GSM-R Interferences points database was created – testimony of the issue, and of its growing trend.

• A collection of legal text and reports text - coming from EC, ECC was made, on one side to support members, and on another for an ongoing analysis for possible contracdictions, duplications, etc.

Together with CER, with the support of EIM and GSM-R IG a letter and a position paper on “Interference into GSM-R due to new mobile communication technologies: was sent to the EC (DG MOVE and DGINFSO), on 15 of February 2011, and following that UIC, together with SNCF and DB representatives joined the Radio Spectrum Committee chaired by DG INFSO and presented the Railwayspoint of view on this very important issue, creating the awareness on this new very important arriving issue, demanding for protection measures.

As an ECC Report – Report 162, describing coordination measures to avoid interferences between public mobile operators and GSM-R networks was agreed between UIC and Public Operators, railways are (repetitively) asking the European authorities to have this report legally binding as reference in any such frequency coordination – reason being that this report defines also the radio environment, and these radio values are critical.

As in Sweden the local authority – PTS was intending to discuss an agreement between the public and GSM-R operators that would involve a reinforcement of the GSM-R network minimum coverage and introduction of filters on board, UIC has reacted during the Swedish public consultation, asking PTS to respect the ECC report 162.

In December 2011, UIC obtained access to an EC test lab, ISPRA, in Italy, and tests have been performed.

The test report is being finalised, and wll constitute the basis for new actions, since it proves that railway assumtions were correct.

A MoU was signed between ECC and UIC, giving UIC the position not only to participate to ECC meetings, but also to be allowed to to start new actions.

In October 2011, in a Conference, DG INFSO declared that “the GSM-R system is not a safety of life system, but also not just a public system. It is now considered to be an “informational system” which if disturbed, could increase the safety risk”.

All meetings documents, meetings minutes included - uploaded on UIC extranet.


8.4 Future Plans

The Frequency Management is an activitythat nrequires more attention that initially is accorded by the railways, frequencies are rare and the technology evolution extremely fast. The interferences to GSM-R, mainly coming from public operators is an issue that if not solved or if solved in a superficial way can cause critical issues on long term – ETCS L2 blocking.

European coordination is needed, and this issue is considerd as being on the highest priority by UIC.

Following actions are prepared:

• Finalize and distribute the test report for the UIC interference test campaign.

• Finalize and distribute the GSM-R Interferences Test report.

• Put in place and populate the new improved Intererences point database

• Create a second version for the UIC Report for interferences to GSM-R.

• Start discussions on solutions like new improved GSM-R network minimum coverage parameters, filters, on board train repeaters, and new strategies and technologies for interference free GSM-R area

• Request further studies on ECC level on the impact of wideband systems in adjacent frequency bands taking into account the receiver performance of a real cab radio receiver.

• Prepare if consiedered an additional test campaign

• Continue the strong lobbying at political level.

9 Network Management Group (NMG)

9.1 Group Members

The NMG consists of representatives from GSM-R Network Operators or Owners of all operational GSM-R networks in Europe. Currently the NMG meetings are attended by Austria, Belgium, the Czech Republic, Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden and Switzerland. Invited are also Great Britain, Greece, Luxemburg and Poland.

When a new GSM-R network becomes active, the Network Operator is invited to join the NMG, to have full benefit of the documents and expertise in order to be interconnected with the rest of GSM-R networks, as soon as needed.

9.2 Group Mission

The GSM-R Network Management Group coordinates all actions to provide roaming and interconnection services for GSM-R users all over Europe in order to have borderless access to the interoperable applications.

The picture below shows the scope of the NMG tasks.


The NMG produces and maintains needed documents (forms, templates, guidelines) supporting the individual GSM-R Network Operators to contract roaming and interconnection on a bilateral basis.

A specific document is the Transit Routing Agreement , which is a multilateral document, signed by all European GSM-R Network Operators. This Agreement arranges that GSM-R traffic between not directly connected roaming partners can cross the European interconnection network without any technical or commercial obstacle.

Another important task of the NMG is to collect and maintain the relevant configuration data of networks, related to numbering plans. This data is used by the ENIR Group and is also relevant for the SIM card configurations. Also figures of the interconnection traffic is collected by NMG and used by ENIR.

Finally, the NMG keeps an eye on the operational procedures related to the international impact of national network changes and planned work. Main goal is to prevent (unexpected) interruptions of roaming services. In close cooperation with ENIR the regular (annual) update of the routing data sets of the interconnection network is scheduled and communicated

9.3 Meeting Reports

In 2011 two meetings were held, 11/12 May in Gottlieben (Switzerland) and 15/16 November in Toledo (Spain).

In addition to the May meeting, a special Workshop has been organized for Managers of the Network Operation Centres of the different GSM-R networks. In this Workshop the international context of GSM-R was emphasized, and background information has been given to underline the need of operational cooperation between the NOC’s.



As the work of the NMG has a continuous character, the main targets are related to the maintenance and update of the standard documents. The most important are:


1. TRA (Transit Routing Agreement), incl. signature administration: also the last GSM-R Network Operator (ADIF, Spain) has signed this TRA. This brings the total on 12.

2. GIRA (GSM-R Interconnection and Roaming Agreement) Template: this document is used as basics for all bilateral agreements.

3. OMA (Operation and Maintenance Agreement) Template: this document is used as basics for all bilateral agreements.

4. TC (Technical Concept) Template: in 2011 a new format is developed. This will replace the old template, called SSDD I&R.

5. N-9004 Roaming Planning (containing all actual and planned roaming services): version 2.01 is published. In total 51 bilateral agreements are signed, of which 13 in 2011.

6. N-9018 GSM-R Network Codes and Network Names: version 1.1 is published.

The latest versions are available on the UIC Extranet.

Specific subjects conducted or monitored by NMG are:

1. International Public Roaming. Germany and Switzerland have reported successful implementation. More countries (e.g. the Netherlands and Austria) will follow soon.

2. Shared Group Call Areas (border crossing Railway Emergency Calls): Germany and Austria have reported successful implementation on two borderlines. In 2012 also SGCA between Germany and the Netherlands will be operational.

3. GPRS roaming: although GPRS is not implemented in all GSM-R networks, standardization can be very helpful. The experiences of e.g. Norway and Sweden will be transferred in a guideline.

4. Harmonisation of Group ID’s, Shortcodes, Function Codes, etc.: the NMG and the Functional Group FG have tasked a small working group to draft a proposal for further harmonization of these items in the GSM-R Numbering plan (Eirene ch. 9), including proposals to solve possible conflicts. The work will be finalized in 2012.

5. GSM-R Network Architecture and upgrades: many Network Operators are planning to introduce more redundancy in their GSM-R networks, given the more and more mission critical character of the application of GSM-R. NMG pushes to work coordination and to limit the service interruptions for roaming users to the minimum.

9.5 Future Plans

For 2012 the NMG will concentrate on the continuation of the ongoing regular work, as described above.

Special attention will be given to the candidate members. The extension of the European GSM-R interconnection and roaming service has to be scheduled in a proper way. The candidates will be supported by the NMG to make their plans and configurations.

A new NOC Managers meeting will be arranged.

The NMG will support UIC to issue the deliverables of the NMG in UIC Leaflets.

10.2 Group Mission

The aim of the ENIR group is a step by step evolution and migration of stand alone GSM-R networks to a European wide overlay network, offering a high availability of roaming services at low cost consumption. In fact the migration is a continuous process.

One of ENIR’s main tasks is the continuous development of the international GSM-R overlay network architecture. Based on standardised and harmonised rules, as well routing principles have to be defined as an agreed guideline for planning the migration to the future overlay network.

In a next step ENIR manages the calculation (adaptation) and distribution of international routing tables (RDS) for border crossing traffic. This is a continuous process, taking into account that every new GSM-R interconnectionor new transit relation requires an adoption of the international GSM-R overlay network. A centralised deployment and control of these international routing tables is essential to provide

optimal routing paths. The defined routing path guarantee high availability by ensuring a second alternate routing path in case of primary link failures. A careful design and implementation of the RDS is required to prevent dangerous circular or ping pong routing.

The coordinated European wide implementation, the so called ‘big bang’, is processed once a year during a weekend night by all interconnected GSM-R operators.

Once the interconnections and the routing tables are in service the load is monitored and analysed. Doing so ENIR is able to follow the trend of the capacity utilisation and can react on a risk of overload accordingly.

e. g. Routing from F to A


Last but not least the ENIR group studies technical related issues rising up in the European GSM-R roaming environment (e. g. Re-routing of public calls).

10.3 European Routing Database Update

GSM-R is more and more - as the networks implementation is advancing and as more and more Cab Radios and EDORS are activated – used in Roaming situation. This proves – after all –that GSM-R is currently fulfilling its task - the interoperable European railway radio system. Since the GSM-R implementation in Europe is a long process, each new implementers when activating its network starts making roaming agreements with its neighbours as well as with other operators whith which ther is a railway transport “business case”, and the international links situation has become more and more complex. That is why the ENIR group decided to study the integration of each individual Routing Data Sets (RDS) - which establishes the main and backup routes for the GSM-R Networks Interconnection. The RDS databases were analyzed by DB Systel, in the frame of the UIC Project GSM-R Network Management. Next step was to decide on a very challenging operation: implementing a unique RDS database in all Networks in Europe, at the same moment, operation ambitiously named “the GSM-R Big Bang”. This moment was chosen for 25 of September 2011, 2 o’clock a.m. A complete schedule of routine checks was put in place. The GSM-R Implementers (Austria, Belgium, Switzerland, Czech Republic, Germany, Spain, France, Italy, The Netherlands, Norway and Sweden) agreed that there was a strong need that all of them accept this concept, and apply the update at same moment. With all previous steps described achieved, the operation took place as scheduled at 25 of September 2011, around 3 o’clock a.m., and is a success, with just some minor outcome to be solved in next period. Therefore, since together with the impressive implementation and roaming operations figures, the European GSM-R networks are today using today a common RDS database, we can now say that the GSM-R networks are proven to integrated – in Europe.


Achievements made by the end of 2011:

• 11 national GSM-R networks are interconnected

• 22 direct interconnections are in operation

• 26 Roaming relations are in operation

• The first European wide RDS implementation ‘big bang’ completed succesfully

• The ENIR guideline GSM-R “Common Design Document” has been expanded by the RDS implementation guide and released in version 1.4

• Technical issues have been discussed and solutions specified

• EINR work results are archived in the workspace on UIC Extranet

• Harmonisation of tones and announcements for unsuccessful calls

• Implementation of Re-Routing of public calls is completed.


The working results are documented in meeting minutes and reports, as well in dedicated guidelines and presentations, which are archived at the UIC Extranet

10.5 Future Plans

• Change-over of a circuit switched network interconnection to a VoIP system architecture and interconnection

• Implementation of new cross-network services (e. g. GPRS)

• Short term, middle term and long term redundancy and disaster tolerance of the international GSM-R overlay network

• (European) Routing Database regular update

11.2 Group Mission

The Future Railway Mobile Telecommunications Systems Study is a UIC activity assessing and shaping the future of railway mobile communications over the next ten years and beyond, based on the predicted GSM obsolenscence.

Participants in the study include national railways, the supply industry and other telecommunications experts. One of the key objectives of the study is to identify suitable candidate technologies – or telecommunication concept - for railways to use after the obsolescence of GSM-R, and first step is to re-define the User requirements, in a technology free way.


The UIC “Future Railways Telecommunication Systems” workshop took place in Vienna on 1 December 2011.

Request for comments were distributed and 175 Comments were received and structured. Draft proposals were prepared for each comment and comments agreed.

The document was thereafter updated and ready for presentation at meeting on 1 December together with a presentation of the main topics requiring modifications in the draft document.

User Requirements Specification final version is till ongoing, due to some comments impact.

Working results are archived at the UIC Extranet:

• Draft proposals for Comments on URS v1.0 • Updated System User Requirements URSv1.1 • Presentation to meeting 1 December

Apart this deliverable work was done together with MERCE R7D Centre, where a CCTV simulation on 300 Km/H was done and presented in the workshop. Discussions were made in peer to peer discussions with suppliers: Nokia Siemens Networks, Kapsch Carrier Comm, Alcatel Lucent, Selex Elsag, Siemens Mobility.

11.4 Future Plans

This activity is considered to be one of the most important, and therefore high priority is accorded by UIC. The activity is going to be organised on project base, with a work leader, targets and deliverables.

Short/medium/long Term program will be prepared before mid of 2012.

First trials are expected around 2014-2015.

Railways telecommunication networks have increased their role in last decade. All Railways important functions and service needs data transport, in reliable and also cost effective way. It is important to understand that Railway telecommunications (needed for rail operations) are not a business case; the business case is the rail transport, where supportive telecommunication services are fostering the railway operations. These systems equipments are majorly off the shelf products; in few cases they are modified off the shelf products (e.g. GSM-R) while for very typical applications – e.g. dispatcher communications specific equipments for critical communications support are needed – e.g. dispatcher terminals. As the technology and the equipments are procured from the public market, this implicit influences their trend. There were 3 meetings organized in 2011, one of them at the kind invitation of Reger telecom, in Lisbon. The Panel of telecom Experts focused on finalizing the first edition of the “IP Introduction to railways Guideline” first edition. The document was released in February 2012. As worldwide telecommunication systems in their totality are converging towards IP; the Railways systems are no exception.


There are understandable concerns coming from instance from traffic management and mainly from signaling experts on the reliability of such an IP infrastructure that would serve a large variety of service, mission critical included. This guideline treats the challenges but also the opportunities when introducing IP to Railways, and provides a set for guidelines, all coming from experience and common effort of the UIC Panel of Experts. IP Guideline version 1.0 content:

• Technological Evolution Overview :

• IP Impact :

• Railway Telecom Network Model :

• Guidelines for Introducing IP : It provides guidelines on the following:

• Network planning

• Network Design

• Technology choices

• Protocols

• Synchronization on IP networks

• Quality of Service and prioritization based on Class of Service

• Network Security and Management

• Considerations for a future proof network.

• Annex – Technology: An in-depth technical explanation on the technologies referenced in this document

Annex – State of the Art Railway Network and Develo pment Plans

12.3 Future Plans

A second edition of the Guideline is planned (beginning/middle 2013, where important subjects like for instance:

o SIP Interface for dispatchers, o Compliance to EN50129/EN50159 o Specifications for the IP Quality of Service requirements for signaling systems o Specification for IP Quality of Service requirements for operational and safety critical

applications, o GSM-R R4 and o Network security issues will be treated.
