Evolution of the Railways Communication System Developments on the

1. Evolution of the Railways Communication System Developments on the Succession of GSM-RPiero Petruccioli Chiel Spaans

2. Why to discuss it now? The Context European Commission: Strong drive for furtherdeployment of ERTMS Availability of radio-communicationis essential GSM-R Stillgrowing, worldwide Deployment and Support at least until 2028 Migration to successortakes long Telecom Market: Continuoustechnicalevolution, driven by public market (3GPP/ETSI) EU Strategyregardingspectrumefficiency/sharing, asset sharing, etc.

3. What is the Challenge To ensure mobile communication for railwayneeds on the long term To ensure a smooth migration to other solution(s) when required To keep costs under control

4. The Main Questions (1) To ensure mobile communication for railwayneeds on the long term What do Railways use today What applications Whatsystems (GSM-R, analog radio, Tetra, public networks) What performance isrealised? Whatisneeded in the future Railwayoperationrelated applications: ETCS and voiceonly? Othersupportive applications? Improved performance? What solution(s) Which are available and future proof

5. The Main Questions (2) To ensure a smooth migration to other solution(s) when required What architecture How to migrateexisting applications towards new radio system, onboard as well as trackside To keep costs under control Whatradionetwork options: (public) standards suitable for railways? own/ shared / public / hybrid? What Spectrum: own/ shared / public?

6. The Principles • The principles are (Brainstorming session 2/7/13, Mr.KarelVinck): • 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.

7. 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

8. The Overall Plan: ERA 3GPP ETSI CEPT UIC Railway Undertakings, Inframanagers ERA/ EC Industry UIC ERA UIC 2013 - 2016 - 2018 - 2020 - 2022 - 2030 UIC and ERA: basis ERA: baseline, legislation UIC + 3GPP/ETSI: standardisation CEPT: spectrum UIC + Industry: development and pilots Users: contract and migrate

9. 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

10. The relation between ERA and UIC • 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

11. 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

12. 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

13. Functionality – What has already been done? COMMON goal : to describe the railwayneeds on the long term, takingintoaccount the continuation of the actual applications and interoperabilityrequirements. Evaluate usage of GSM-R 2013: ERA : Ex-Post analysis of GSM-R operation (Questionnaire) Investigate future trends and applications 2010: UIC draft User RequirementSpec 2013: ERA Study on evolution of communication 2012-2013: monitoring developments in other critical communication sectors

14. Spectrum COMMON goal: to define the needed spectrum and conditions. Subjects to be studied: Spectrum opportunities Availability/suitability of the extended GSM-R-band Co-existence of new technology and GSM-R in these bands Radio planning aspects Spectrum size calculation (actual, mid term, long term) Synchronisation withothersectors (PPDR) Possibilities for « networks withgovernmentaltasks »

15. 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 items Interfacing/sharing with other networks Railway specific voice applications via IP ETCS over Packet Switching/IP Radio aspects, asset re-use Evolution/migration scenarios

16. 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
