UIC ERTMS Conference, Istanbul 01-03 Apr 2014
Why to discuss it now? The Context
European Commission: Strong drive for further deployment of ERTMS Availability of radio-communication is essential
GSM-R Still growing, worldwide Deployment and Support at least until 2028 Migration to successor takes long
Telecom Market: Continuous technical evolution, driven by public market
(3GPP/ETSI) EU Strategy regarding spectrum efficiency/sharing, asset sharing,
etc.
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
What is the Challenge
To ensure mobile communication for railway needs on the long term
To ensure a smooth migration to other solution(s) when required
To keep costs under control
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
The Main Questions (1)
To ensure mobile communication for railway needs on the long term
What do Railways use today What applications What systems (GSM-R, analog radio, Tetra, public networks) What performance is realised?
What is needed in the future Railway operation related applications: ETCS and voice only? Other supportive applications? Improved performance?
What solution(s) Which are available and future proof
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
The Main Questions (2)
To ensure a smooth migration to other solution(s) when required
What architecture How to migrate existing applications towards new radio system,
onboard as well as trackside
To keep costs under control
What radionetwork options: (public) standards suitable for railways? own / shared / public / hybrid?
What Spectrum: own / shared / public?
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
The Principles
The principles are (Brainstorming session 2/7/13, Mr. Karel Vinck):
Evolution to IP based technologies.
Split the application and the communication layers for voice and data communications.
Involve telecom operators.
Use off the shelf technology, no dedicated development.
Common operational requirements
Maintain a high level of safety
Promote the evolution in a structured way.
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
The ERA Program key points GSM-R will still be used for a long time.
Any evolution path will be compatible with the current GSM-R networks. Support to GSM-R will continue in parallel.
The main targets: By end 2014: to have a clear view on the network models to be
used
By 2018: to have these models fully described (changes in TSI)
By 2022: to be able to procure network and
on board based on the new system described
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
The Overall Plan:
ERA UIC
ERA 3GPP ETSI CEPT UIC
ERA/ ECIndustry UIC
RailwayUndertakings,Inframanagers
UIC and ERA: basis ERA: baseline, legislation
UIC + 3GPP/ETSI: standardisationCEPT: spectrum
UIC + Industry: development and pilots
Users: contract and migrate
2013 - 2016 - 2018 - 2020 - 2022 - 2030
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
The ERA role : Program manager The Commission has appointed ERA to manage the Program to
define the evolution of the railway communication system
The Program should allow the structured development of the technical (TSI) documents
The Program Manager tasks: Establish the input required from different
working groups and the deadlines to receive the results of the discussions
Establish the input required from different projects (UIC, projects in Member States, Infrastructure Managers and Railway Undertakings), and the deadlines to receive the results/deliverables
Coordinate the results received with the support of the stakeholders
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
The scope of ERA and UIC are complementary and convergent to the same target
ERA:
•focus on legal text (evolution of Baseline 0), feasibility of the business case, interoperability, stakeholders’ interest
UIC:
•focus on standardisation, evolution of EIRENE, additional applications, interaction with standardisation bodies and industry
The relation between ERA and UIC
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
The UIC role: Studies & Standardisation
UIC has started a project in 2014: FRMCS project (Future Railways Mobile Communication System)
Functional and Technical research of harmonized solutions for technologies to succeed GSM-R
Budget committed for three years (2014-2016)
Substantial support from UIC members
Active participation of several UIC members
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
The UIC work plan
3 workstreams identified:
Functionality : to describe the railway needs on the long term,
taking into account the continuation of the actual applications and requirements
Spectrum : to identify the needed spectrum and conditions
Technology & architecture : to prepare the decision on the future technolog(y)(ies) and the conditions
First work items are related to functionality
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
Functionality – What has already been done?
COMMON goal : to describe the railway needs on the long term,
taking into account the continuation of the actual applications
and interoperability requirements.
Evaluate usage of GSM-R 2013: ERA : Ex-Post analysis of GSM-R operation (Questionnaire)
Investigate future trends and applications 2010: UIC draft User Requirement Spec 2013: ERA Study on evolution of communication 2012-2013: monitoring developments in other
critical communication sectors
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
Spectrum
COMMON goal: to define the needed spectrum and conditions.
Subjects to be studied:Spectrum opportunitiesAvailability/suitability of the extended GSM-R-bandCo-existence of new technology and GSM-R in these bandsRadio planning aspectsSpectrum size calculation (actual, mid term, long term) Synchronisation with other sectors (PPDR)Possibilities for « networks with governmental tasks »
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
Technology & Architecture
Main UIC goal: to prepare the transfer of the functional requirements to the future technolog(y)(ies) and the conditions.
Candidate subjects to be studied:Network Architecture evolution (3GPP/ETSI)On-board Architecture (IEC?)Railway specific architecture itemsInterfacing/sharing with other networksRailway specific voice applications via IPETCS over Packet Switching/IPRadio aspects, asset re-useEvolution/migration scenarios
UIC ERTMS Conference, Istanbul 01-03 Apr 2014
Conclusion
Work on succession of GSM-R has started All needed parties are involved Milestones are defined Synchronised project activities have been started
Note:
GSM-R will be the only standard for many years
