why gsm r
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!

gsm r renewals and improvements
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)

release 4 core
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

renewal of gsm r radio access network ran
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
er gsm capacity increase option
ER-GSM - Capacity Increase Option
  • Additional ER-GSM frequencies (4 + 3MHz)
    • 75% more GSM-R capacity

validation of gsm r test specifications
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

new professional radio standardization in 3gpp
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
