2. 2 INDUSTRY GROUP 2 GSM-R - State of the Art and Close Future Trends 2 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 Agenda

3. 3 INDUSTRY GROUP 33 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!

4. 4 INDUSTRY GROUP 44 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)

5. 5 INDUSTRY GROUP 5 Release 4 Core  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 the control 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 TDM* - Time Division Multiplexing, 3GPP** - 3 rd Generation Partnership Project

7. 7 INDUSTRY GROUP 7 www.gsm-rail.com Geographical Redundancy Two geographically distant GSM-R Core & Central Dispatcher Nodes to protect against Disasters GSM-R Core on Location AGSM-R Core on Location B GSM-R Dispatcher Node

8. 8 INDUSTRY GROUP 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. 9 INDUSTRY GROUP 9 ER-GSM - Capacity Increase Option Additional ER-GSM frequencies (4 + 3 MHz) 75% more GSM-R capacity E-GSM Downlink Uplink GSM E-GSMGSM Public Users Railways 960 918 915 873 880 925

13. 13 INDUSTRY GROUP 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 1.A mandatory and sufficiently thorough test spec will guarantee a certain GSM-R quality all over Europe 2.Efforts for verification of compliance with TSI requirements predictable 3.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

14. 14 INDUSTRY GROUP 14 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 New Professional Radio Standardization in 3GPP
