1 Implementation status : GSM-R Robert SARFATI UIC ERTMS/GSM-R Operators Group Chairman ETSI Technical Committee Rail Chairman SYSTRA FIRSE

2 Background: GSM-R an European choice In Europe, existing standard technologies were considered for the new digital radio technology, The choice of GSM was finalized in GSM-R standards were developed based on GSM R99 technology and included all railways specific requirements and an allowance of a specific additional frequency range Enhanced Location Dependent Addressing (elda) Enhanced Railway Emergency Call (erec) Short Message Service to Functional Number l Applications Functional Numbering Location Dependent Addressing High speed up to 500 km/h Railway functional Requirements (EIRENE) Voice Group Call Service (VGCS) Voice Broadcast Service (VBS) Enhanced Multi Level Precedence and Preemption (emlpp) All functionalities available for GSM-R including General Packet Radio Service (GPRS) Enhanced Data Rates for GSM Evolution GSM enhancements for railways ( ETSI EN301515) ) Standard GSM functionality

3 PMR functionalities of GSM-R GSM-R is a worldwide standard, developed within the frame of the GSM/3GPP standards to include Rail & Transport needs. - It includes a dedicated radio spectrum for exclusive rail use, all over Europe ( / MHz) with extension possible within ( / MHz) for worldwide application. - It includes features specific for Railways operations. - It is the bearer for ETCS and Track-to-Train radio. - It allows for evolution towards new features such as Packet Switching GPRS/EGPRS and Release 4 architecture.

6 From an European standard GSM-R is in operation in most of the European Countries and ETCS L2 roll out is based on GSM-R. 70,000 km of track are in GSM-R operation just in Europe and 84,000 km more are planned to be covered in addition* GSM-R is expanding worldwide: 138,000 km are planned to be covered outside Europe. ** *) source: UIC e-news 311 **) source: Kapsch CarrierCom, Nokia Siemens Networks - GSM-R in operation

9 From the European Legislation perspective MoU ERTMS A Memorandum of Understanding ERTMS was signed between the European Commission, European Railway Agency and the Rail Sector Organisations : The Parties note the commitment of the GSM-R Industry Group members to the long-term support of GSM-R technology, at least until Nevertheless telecommunications systems usually have a much shorter life cycle than signalling systems. For this reason, it should be possible to replace the 'telecommunications part of onboard equipment without this having an impact on the 'safety critical signalling path. Today ETCS applications work with GSM-R circuitswitched services. It does seem possible, however, to use packet-switch systems (e.g. GPRS) and, in the longer term, other IP-based standards, without impacting on the ETCS specifications. Operators 9 Group Chairman

Transmission network IP Guideline IP QoS GPRS/EGPRS for ETCS BSS BSC BTS Technical Specification Railway Telecommunications (RT); Global System for Mobile communications (GSM); Usage of Session Initiation Protocol (SIP) on the Network Switching Subsystem (NSS) to Fixed Terminal Subsystem (FTS) interface for GSM Operation on Railways Growing, improved applications

Transmission network : IP introduction within distribution network IP BSS: Full IP end to end

12 Step 3: BSS & Terminals migration Foreign Network From R99 To R4+ features FTS NSS: From R4 to R4+ Core Network architecture and features NSS to FTS: SIP phase 2 introduction at Interface Transmission network : IP introduction within distribution network IP BSS: Full IP end to end interface over the Abis interface of BSS Terminals Software Defined Radio VoIP over the Air interface BSS BSC BTS

13 Conclusion The analysis showed that communication technology evolution is not complete, but the IP based technology is the stable platform. The worldwide evolution shows that 3GPP UMTS is still a long term technology for voice and preserves more than 80% of railways assets while evolving toward IP. The roadmap for evolution should be «railways needs evolution» based, not «technology only» driven. GSMR-IP is today offering a Global answer to Users needs, allows from the Shelves delivery, ensures Multi-supplier environment, is Reliable, prepared for Innovation and answers Promises.
