This is intended to demonstrate that by linking GSM-R networksand railway-owned fixed networks it will be possible to replace the existing UIC railways’telecommunication network and to improve the quality and usability of the new network compared to theexisting one.The planned GPRS activities have also continued, following the initial study to gather information aboutthe availability of GPRS in GSM-R networks and the need to upgrade existing standards to be usable inthe railway environment. The current definition of ETCS mandates the use of circuit-switched datatelecommunications, but use of GPRS for ETCS could potentially increase the capacity of GSM-R - aparticular benefit in congested areas. A workshop held in September at UIC has demonstratedconsiderable interest on the part of the railways in supporting further work on the use of GPRS as a firststep in the direction of an IP-based network.The updating of the MORANE documents, which remain the basis for GSM-R implementations, hasprogressed. The documents have been delivered by GSM-R industry for check and approval. The finalversions have been received and an official print-out will be available at UIC. The new set of test-cases forcab-radios, where a contract with Kapsch has been set up, is already available as a first draft. Some workhas still to be done in the coming weeks. All these documents will need to undergo the new changecontrol process of the ERA.3. Scientific and technical overviewWorking GroupsERTMS/GSM-R project activities are mainly centred on two permanent working groups, the FunctionalGroup (FG) and the Operators Group (OG).The principal task of the Functional Group is to maintain the EIRENE FRS and to create the necessaryChange Requests (CR’s) to close gaps in the specification, clarify requirements and insert newrequirements based on results of current implementations.The FG is the first forum for discussion of implementation reports coming from the railways and industry.FG is also the body that provides support to the railways and other organisations concerning functionalrequirements and future applications. The FG also takes into account expertise from railways andtechnical bodies.The task of the Operators Group is to maintain the EIRENE SRS and relevant technical documentation,such as the MORANE documents. The OG also creates CR’s as required, and reviews those - mainlybased on functional requirements – received from the FG. The CR’s describe technical solutions and takealso into account results of technical expertise from the GSM-R Industry group and from other experts.In addition, the OG maintains an Implementation Report Summary document, recording progress withresolving technical issues that have arisen. The OG determines whether Reports need to be forwarded tothe GSM-R Industry Group for further technical assistance.The OG is the interface between the project and the GSM-R Industry Group and also between the projectand ETSI Technical Committee – Railway Telecommunications (TC-RT – see below).

A 7 of 14As the early implementations and first interconnections of GSM-R networks have shown, there are somecases of discrepancies in the interpretation of Standards. The volume of work involved in resolving someof these issues and the generation of appropriate CR’s can exceed the resources of the permanentworking groups. In these cases, it has been necessary to set up ad-hoc working groups.The ad-hoc groups currently in existence are:- Border Crossing- Common set of test cases- eREC (enhanced Railway Emergency Call)- ETCS Data-only Radio- FFFIS for Shunting- FFFIS for SIM-Cards- Frequency issues- GPRS- International Numbering- Interoperability testing (IOT)- Quality of serviceTC-RTThis group forms the interface to ETSI. The group is set up with representatives of the OG and FG andincludes members of the GSM-R Industry . The main task of this group is the investigation of existingGSM standards and the creation of CR’s to these standards. Liaison statements to 3GPP and otherstandardization bodies guarantee that the requirements and restrictions of the railways are taken intoaccount.Change Control GroupsThe ERTMS/GSM-R Project also embraces the work of Change Control Management, in conjunction withERA, UNISIG and other recognised European sector organisations. The principal tasks are submission ofCR’s into this process, evaluation of economic impact and assessing CR’s coming from ETCS with regardto their impact on GSM-R.This process comprises two levels, the Change Control Group (CG ERA) and the Change Control Board(CCB). The CG ERA is made up of members from the different sector organisations including CER andEIM (the Project-Manager represents CER and UIC), with the participation of the GSM-R Industry Group.At CCB level, the project is represented by the Project Manager and the Speaker of the Industry Group.European Radio Implementation Group (ERIG)Overseeing the activities of all the constituent working groups of the ERTMS/GSM-R project is ERIG. Thisforum comprises representatives of all railways actively implementing GSM-R and railways that havesigned the EIRENE MoU and are close to starting the implementation process.ERIG is kept informed of progress with implementation and lessons learned in this process, as well asupcoming standards, applications and technical progress. The forum gives formal acceptance to ChangeRequests created by the FG, OG and IG and supports new versions of specifications. It also approves the
