2. ALSTOM FREQUENTIS HFWK KAPSCH NORTEL SAGEM SELEX SIEMENS WENZEL 2 INDUSTRY GROUP Version Management - Drivers for standardisation - YESTERDAY Legacy Rail comm. systems  Custom specific development  One shot solution  Interoperability ends at border  Loss of expertise over lifecycle  Reduced Maintainability over lifecycle (ops and hardware) TODAY GSM-R systems  Interoperability  Interchange ability  Competitive product supply  New rail features globally  New wireless features, GPRS..  Maintainability  Economy of scale  Compliance to latest EC directives, TSI’s

3. ALSTOM FREQUENTIS HFWK KAPSCH NORTEL SAGEM SELEX SIEMENS WENZEL 3 INDUSTRY GROUP Benefits of standards evolution and diversified networks  GSM-R networks making use of basic GSM components  Voice Mail  SMS  GPRS  SIM OTA  EIRENE refers to a set of:  53 normative GSM specifications (ETSI)  13 normative Rail specifications  Standards evolution and diversified networks are welcome  Diversified set of suppliers  Railways buy of the shelf products to accomplish their GSM-R plus demands  Suppliers are GSM but not GSM-R centric  Evolution of standards today  Over 400 rail specific CRs received from Railways  Multitude of ETSI GSM CR’s processed  Version management ensuring system integrity is required

7. ALSTOM FREQUENTIS HFWK KAPSCH NORTEL SAGEM SELEX SIEMENS WENZEL 7 INDUSTRY GROUP Real live example GSM-R IOT’s Counter complexity of testing efforts with intelligent version management  efforts increase with system complexity  Test matrix multiplies to allow vendor & version richness

8. ALSTOM FREQUENTIS HFWK KAPSCH NORTEL SAGEM SELEX SIEMENS WENZEL 8 INDUSTRY GROUP Life cycle management / Version management 3GPP  Industry adopted life cycle management for mass market product  industry best practices tolerate impact to QoS Railways  IOT test campaigns and regressions  QoS impact not acceptable  “Managed” evolution strategy required  Version Management keys  Evolution Authority  GSM-R lifecycle  Upgrade strategy  System integrity criteria Active Version X+1 Inactive Version X-1 Active Version X Time

9. ALSTOM FREQUENTIS HFWK KAPSCH NORTEL SAGEM SELEX SIEMENS WENZEL 9 INDUSTRY GROUP Best Practises - 3GPP & GCF  Defined minimum set of rules to certify compliancy  On minimum diversified systems  Full type approval (FTA) covers compliancy fatalities only  Do not cover GSM-R specifics  Valid for t=T0 only  No regression testing after t0  Non compliancy triggered through customer complaints  non compliancy usually resolved with hardware upgrade Third Generation Partnership Project (3GPP) & Global Certification Forum (GCF)

10. ALSTOM FREQUENTIS HFWK KAPSCH NORTEL SAGEM SELEX SIEMENS WENZEL 10 INDUSTRY GROUP Version Management proposition  GSM-R IG submitted Version Management concept paper  Under review in European Railway Agency, ERA  Describes managed process  Supervised by an ERTMS System Authority  Railways and Industry contribute to initiatives  Common objectives:  Allow evolution of standards  Commit interoperability  Ensure system integrity over lifecycle
