IP based applications, sub-systems and interfaces
• Applications and services evolving to IP Recording, ETCS
• Sub-systems evolving to IP NSS, FTS, Mobiles
• Interfaces evolving to IP between and within sub-systems
• Future IP based architecture and interfaces
– “all over IP“ as e.g. LTE
• Choosen interface technology SIP, IP
– Basis of future systems
– e.g. LTE IP, IMS SIP

Motivation and goals for migration
• Apply new technology, IP, where feasible overcome obsolesence
• Follow commercial market and products decrease cost
• Do not change the whole system at once secure investments
Gain from IP benefits but address challenges!

IP benefits & challenges
• Benefits
– One multi-service network for different types of applications
– Increase of reliability & availability (resilient architecture)
– Efficient use of limited capacity at the interfaces in question
• Challenges
– Quality-of-service
– Security
– “Interconnection and interworking with legacy, already rolled-out systems
– Future proof implementation vs. decreasing life-cycle of off-the-shelf
components

Standardisation concerning IP migration
• UIC / ERA
– Guidelines
– Change requests and requirements
– FRMCS project to compile requirements for next generation system
• GSM-R TIG
– Review of change requests and requirements
• technical feasibility
• commercial impact
• ETSI Technical Committee for Railway Telecommunication
– Technical specifications
– Dedicated working group for next generation system (NG2R)

Update on “IP and SIP Interfaces” at ETSI
• Interface between NSS and FTS (ETSI TS 103 389 – v3.0.0)
– NSS/FTS to Voice Recording System
– Supplementary services (in line with EIRENE requirements)
• “A over IP” (NSS – BSS)
– Change requests prepared by TC RT under approval within ETSI and 3GPP
• “A-bis over IP” (BSC – BTS)
– Working on definition of a Technical Report (TR) for “Abis over IP“
• “GRPS/EDGE requirements for ETCS“ (ETSI TS 103 320)
– Define which (already published standards) are applicable to rail
• “AT commands for GPRS/EDGE operation“
– Interface within the On-Board Unit
– Interface to the GSM-R mobile termination changes because of the bearer

Implementation works and roll-out
• Evolution & migration of GSM-R core network from
“Release 99“ to “Release 4“
– Austria, Germany, Great Britain, Norway, …
• Roll-out of IP based controller equipment (core nodes and terminals)
– Norway, Ireland, Lithuania, …
• Possible implementation of SIP based interface between
NSS and FTS
– Germany, …
• ETCS over GPRS
– Great Britain, …

Going beyond evolutionary approach for IP
• IP is already defined as basic technology for next generation
communication (by UIC, ERA and industry)
• Current IP evolution enables future path to an IP based railway
communication system will end up in “next generation architecture”
• IP capable user-devices are continuously rolled-out
• Services, including railway specifics, will be accessible independent of
access technology and service distribution
• Other domains support and drive standardisation, e.g. 3GPP MCPTT and
OMA PCPS standards for mission critical services expected 2016
MIGRATION to FRMCS is already on the way and progresses!
