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
INDUSTRY GROUP
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

Release 4 Core
INDUSTRY GROUP
 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** - 3rd Generation Partnership Project

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

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
