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
Why GSM-R?
INDUSTRY GROUP
• 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
!
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)

Renewal of GSM-R Radio Access Network RAN INDUSTRY GROUP
• 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
ER-GSM - Capacity Increase Option INDUSTRY GROUP
• Additional
ER-GSM
frequencies (4
+ 3 MHz
) • 75% more GSM-R capacity 873 880

Validation of GSM-R Test Specifications
•
INDUSTRY GROUP
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
New Professional Radio Standardization in 3GPP INDUSTRY GROUP
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
