  1. GSM-R State of the Art and Close Future Trends UIC ERTMS World Conference Istanbul 1-3 April 2014 Ola BERGMAN Head of GSM-R Standardization NSN www.gsm-rail.com

  2. GSM-R - State of the Art and Close Future Trends Agenda Why GSM-R? GSM-R Renewals and Improvements GSM-R Interoperability/Compatibility Testing IOT Validation of GSM-R Test Specifications New Professional Radio Standardization in 3GPP 2

  3. Why GSM-R? • Under UIC leadership a modern Railway Mobile System was specified during the 90’s – GSM-R – replacing analogue technology… • …and has been refined over the years since then • It includes all required voice and data features for Railway Operation • GSM-R is Interoperable and Multivendor • GSM-R has a very large footprint – in Europe and internationally • GSM-R is a true success story! 3

  4. GSM-R Renewals and Improvements • Ongoing in existing Networks/Systems • Shift to Internet Protocol IP • Introduction of Release 4 GSM-R Core, GPRS footprint • Geographical Redundancy for Improved Core Availability • Renewal of RAN • Mitigation of Radio Interferences • Upgrades to ETCS L2/3 bearer capability • In Advanced Stage of Standardization • ER-GSM - Capacity Increase Option • ETCS over Packet Switching (GPRS/EDGE) 4

  5. Release 4 Core TDM* - Time Division Multiplexing, 3GPP** - 3rd Generation Partnership Project • Upcoming GSM-R Core Network is the evolution of legacy TDM* based Core to Packet Based Core – from Release 99 to Release 4 • The Bearer Independent Core Network architecture is defined by 3GPP* * in Release 4 specifications and since years widely deployed in public mobile networks around the world serving millions of subscribers • Physical Separation of thecontrol and signaling telecom layer - MSC Server from the bearer plane - Media Gateway • Release 4 is fully compliant with UIC EIRENE specifications and ERA GSM-R baselines • Release 4 is a major milestone towards Internet Protocol IP

  6. GPRS deployments  LiveIn deployment

  7. Geographical Redundancy Two geographically distant GSM-R Core & Central Dispatcher Nodes to protect against Disasters GSM-R DispatcherNode GSM-R DispatcherNode GSM-R Core on Location A GSM-R Core on Location B

  8. Renewal of GSM-R Radio Access Network RAN • First GSM-R systems were deployed starting 1998 • Since then radio technology has improved significantly • Less power consumption, less footprint, improved functionality, better maintainability,... • Several Railways are updating/planning to update the Radio Access Network RAN, i.e. to renew the Base Station Subsystem BSS

  9. ER-GSM - Capacity Increase Option • Additional ER-GSM frequencies (4 + 3MHz) • 75% more GSM-R capacity Uplink Downlink 873 880 925 915 918 960 E-GSM GSM E-GSM GSM Public Users Public Users Railways Railways

  12. GSM-R Inter Operability Testing (IOT) 2014 co-financed by the European Commission EIRENE 5/13 Issued 2000 EIRENE 6/14 Issued 2003 EIRENE 7/15 Issued 2006 EIRENE 7.4.0/15.4.0 EIRENE 7.3.0/15.3.0 Q1/ Q4 2005 2002 Q2/ Q4 2004 Q1 2007 Q1 2011 Q2 2011 Q3 2011 2014 • IOT Phase 3 Initial & Regression • NSN and Nortel - NSS/ NSS & NSS/ BSS EIRENE 5/13 • Inter PLMN connections tested • Additional features tested • GlobalIOT Phase X Specs • GSM-R NSS/ • NSS & NSS/ BSS & E to E • QoS • Global IOT Phase 1&2 • Nortel and NSN - NSS/ NSS & NSS/ BSS EIRENE 5/13 • Static roaming functionality • GSM services • Advanced Rail services • GlobalIOT & Field Phase 4.1 • Nortel BSS to NSN NSS EIRENE 6/14 • GlobalIOT Phase 9.3 • KCC BSS to NSN NSS EIRENE 7/15 • GlobalIOT Phase 9.2 • KCC NSS to NSN BSS EIRENE 7/15 • GlobalIOT Phase 9.1 • KCC NSS to NSN EIRENE 7/15NSS • GlobalIOT Phase 4.2 • Nortel NSS to NSN BSS EIRENE 6/14 • IOT Phase 3 extension • Focus on additional features (late entry, eMLPP, Call barring and Access Matrix, Class of Registration, …)

  13. Validation of GSM-R Test Specifications • The ERTMS MoU signed in April 2012 stipulates: “The GSM-R test specifications for conformity assessment of GSM R on-board radios and networks will be validated and included in the TSI CCS” • GSM-R IG addresses by performing validation test campaigns 2013 and 2014 – coordinated with ERA • The reason for GSM-R IG to invest in this is three-fold • A mandatory and sufficiently thorough test spec will guarantee a certain GSM-R quality all over Europe • Efforts for verification of compliance with TSI requirements predictable • Commonly agreed test specs imperative for European Cross-acceptance - also allowing for ”reusage” of e.g. generic ISV • All these contributing to better efficiency and lower costs for both Railways and Suppliers • GSM-R IG is strongly in favour of including the Test Specs in the CCS TSI 13

  14. New Professional Radio Standardization in 3GPP • Critical Communications (ref GSM-R Group Call functionality) currently in 3GPP work planned for inclusion in Release 12 • Group Call System Enablers over LTE (GCSE_LTE) • ProSe • Mission Critical PTT over LTE (MCPTToLTE) • This standardization is driven by Users and Suppliers of Public and Professional Mobile Radio aiming at one Common, Efficient, Fully Featured and User Friendly solution… • …aiming at many Users - potentially entire Public Safety Sector … • Interesting to follow progress with regards to a Next Generation system following after GSM-R 14
