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.


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


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


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?


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.


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


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


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


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


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


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


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


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 »


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


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
