UIC ERTMS Conference, Istanbul Apr 2014 Evolution of the Railways Communication System Developments on the Succession of GSM-R Piero Petruccioli Chiel Spaans

UIC ERTMS Conference, Istanbul 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 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 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 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 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 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 Apr 2014 The Overall Plan: ERA UIC ERA 3GPP ETSI CEPT UIC ERA/ EC Industry UIC Railway Undertakings, Inframanagers UIC and ERA: basisERA: baseline, legislation UIC + 3GPP/ETSI: standardisation CEPT: spectrum UIC + Industry: development and pilots Users: contract and migrate

UIC ERTMS Conference, Istanbul 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 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 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 ( )  Substantial support from UIC members  Active participation of several UIC members

UIC ERTMS Conference, Istanbul 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 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  : monitoring developments in other critical communication sectors

UIC ERTMS Conference, Istanbul Apr 2014 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 with other sectors (PPDR)  Possibilities for « networks with governmental tasks »

UIC ERTMS Conference, Istanbul 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 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

UIC ERTMS Conference, Istanbul 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
