Background: GSM-R an European choice

In Europe, existing standard technologies were considered for the new

digital radio technology, The choice of GSM was finalized in 1995.

GSM-R standards were developed based on GSM R99 technology and

included all railways specific requirements and an allowance of a

specific additional frequency range

Functional Numbering

Location Dependent Addressing

High speed – up to 500 km/h

Voice Group Call Service (VGCS)

Voice Broadcast Service (VBS)

Enhanced Multi Level Precedence and Pre-

emption (eMLPP)

All functionalities available for GSM-R including

General Packet Radio Service (GPRS)

Enhanced Data Rates for GSM Evolution

Enhanced Location Dependent Addressing

(eLDA)

Enhanced Railway Emergency Call (eREC)

Short Message Service to Functional Number

Railway functional Requirements

(EIRENE)

GSM enhancements for railways ( ETSI EN301515) )

Standard GSM functionality

CCRCC Conference




GSM-R is a worldwide standard, developed within the

frame of the GSM/3GPP standards to include Rail &

Transport needs.

- It includes a dedicated radio spectrum for exclusive

rail use, all over Europe (876-880 / 921-925 MHz) with

extension possible within (873-915 / 918-960 MHz) for

worldwide application.

- It includes features specific for Railways operations .

- It is the bearer for ETCS and Track-to-Train radio .

- It allows for evolution towards new features such as

Packet Switching GPRS/EGPRS and Release 4

architecture.

From an European standard

GSM-R is in operation in most of the European

Countries and ETCS L2 roll out is based on GSM-R.

70,000 km of track are in GSM-R operation just in

Europe and 84,000 km more are planned to be

covered in addition*

GSM-R is expanding worldwide: 138,000 km are

planned to be covered outside Europe. **

GSM-R an evolving system

CCRCC Conference




From the European Legislation perspective

MoU ERTMS– A Memorandum of Understanding ERTMS was

signed between the European Commission, European Railway

Agency and the Rail Sector Organisations :

The Parties note the commitment of the GSM-R Industry

Group members to the long-term support of GSM-R

technology, at least until 2025. Nevertheless

telecommunications systems usually have a much shorter

life cycle than signalling systems. For this reason, it should be possible to replace the 'telecommunications part of on-

board equipment without this having an impact on the

'safety critical signalling path.

Today ETCS applications work with GSM-R circuit-switched services. It does seem possible, however, to use

packet-switch systems (e.g. GPRS) and, in the longer term,

other IP-based standards, without impacting on the ETCS

specifications.

Conclusion

The analysis showed that communication technology

evolution is not complete, but the IP based technology is

the stable platform.

The worldwide evolution shows that 3GPP UMTS is still a

long term technology for voice and preserves more than

80% of railways assets while evolving toward IP.

The roadmap for evolution should be « railways needs

evolution » based, not « technology only » driven.

GSMR-IP is today offering a Global answer to Users needs,

allows from the Shelves delivery, ensures Multi-supplier

environment, is Reliable, prepared for Innovation and

answers Promises.
