Presenter

Presentation Notes

In the 80’s, the train radio communication were based on analogue systems, which were extremely diversified The analogue were mostly walkie talkie systems, simplex systems With limited range, and limited application posibilities, mostly on voice With large number of staff speaking on the same channel Without encryption, and with different frequency spectrum


Why GSM-R• Europe has an important focus on the Rail Transport, safe and

environmental friendly• The Council Directive 91/449/EEG of 29 July 1991 concerning the

development of Railways in the European Community stated that “there is a need for a new telecommunications, which must:– be open and non-proprietary, i.e. standardized, allowing competition between

telecom suppliers – be nationally interoperable– allow international train traffic– allow open competition between train operators– support new, standardized train control systems (ETCS)– be future-proof– be able to support safety voice communication and other railway functionality– be able to support the business needs of track owners and train operators

(telemetry, freight tracking…)

Presenter

Presentation Notes

Europe has an important focus on the Rail transport, safe and enviromental friendly. In this context,


• 1992 until 2000 – the GSM-R specifications (EIRENE - European Integrated Railway Enhanced NEtwork) were defined and validated (MORANE- MObile radio for RAilway Networks in Europe) by a group of manufactures and operators.

• 1994, Standardization of Advanced Services Call Items (ASCI) features (special railway performance and operational requirements) start at ETSI

• 1996 - GSM-R is mandated by European Directive, in the frame of ERTMS.

• MoU to GSM-R commitment was signed in 1997 by 32 European railways

• 1999 – The frequency band 876-880 paired with 921-925 MHz was allocated to GSM-R by European Law

• In June 2000, an EIRENE Agreement on Implementation (AoI) was signed by 16 railways, as a complement to the EIRENE Memorandum of Understanding;

The Milestones

Presenter

Presentation Notes

In UIC we have looked we have decide after a series of studies to chose GSM as the basis of the new Radio system, which was an existing system, standardised, future proofed. We have noticed that the GSM applications were not enough for the Railway needs, so we have started in 1992 to write the specifications of the new system; describing the requirements of a mobile networks fulfilling the railways needs and ensuring interoperability across the borders Iin 1995 a first draft f the specifications was ready; we called them EIRENE; we have validated them in field test the specifications, inside the project called Morane. The first EIRENE specifications, validated, were ready in 2000. In 1994 we have started to standardize the ASCI features within ETSI In 1996, in the context of ERTMS, GSM-R was mandated as the new european digital radio system In 1997, we have prepared a MoU, committing the signatories railways to invest in GSM-R and not any more in analogue radio; the MoU was by 32 railways In 1999, we by European law, the bandwidth… was allocated to GSM-R In addition to the declaration of willingness set out in the MoU, the we have also p[repared an Agreement of Implementation (AoI), where the signing railways committed themselves to start their implementation of the national GSM-R system in 2003 at the latest. This AoI was signed by 17 railways.

Presenter

Presentation Notes

GSM-R is based on GSM. Standardised in ETSI and future proof due to huge public usage. The GSM-R standardising body decided for GSM in the MORANE trials in the mid 90’s. Tested in Germany, France and Italy. Standardised in EIRENE. Every functionality is tested to be interoperable with other GSM-R functionalities and vendors.

system, including ASCI (Advanced Call Speech Items)

• It adds specific features for Railways operations

• It has dedicated valuable radio spectrum for rail use, all over Europe

• It is the bearer for ETCS, voice, and various data applications

• It fulfils strong Quality of Service requirements

Presentation Notes

GSM-R is the new radio digital system for the railways, and the bearer for ETCS. It is based on ETSI GSM, and it is a standard If we would look for a simple definition for GSM-R, we could say, that is a GSM system, with all its functionalities, with ASCI Adds, like eMLPP, Voice Broadcast calls and Voice Group Calls, and with Railways Features, like FN, LDA, Access Matrix, REC, speed up to 500 km/h, etc. GSM-R is required to have a very high network availability for voice and data communications; translated into a high Quality of Service requirements. Seen as a simple equation: click

Presenter

Presentation Notes

The frequencies allocated to GSM-R are close to GSM 900 band, where we find the Public Operators; they are paired frequencies for mobile communicating with the network as well as network communicating with the mobile. We have a 4 MHz spectrum which means 19 frequencies Each frequency has 8 communicating channels, from which 6 are used exclusively for communications In order to speak between two users, we need a channel. This would lead theoretical to 19*6= 114 voice channels, but due to radio planning constraints such amount of channels is never available in a single place.

Presentation Notes

GSM-R is an end to end system, which means that on one side we have the mobile stations, which arte handhelds, for general or operational use, and the cab radios, and on the other side we have the fixed dispatcher terminals, integrated in the GSMR network. In the middle, we have the Network We have invested a lot of work and money to prove for each component that is interoperable which all the others, including the two actual network suppliers between themselves. Interoperability is a primordial feature, together with the fulfilment of the railway requiremets

GSM-R Applications

Presenter

Presentation Notes

As the main purposes, GSM-R is the bearer for ETCS and the new radio digital system for the Railways. It is also used for operational voice communication for railway staff, like maintenance or working groups, and it support also the shunting. GSM-R, through SMS or GPRS calls is also used for Train Maintenance, sending diagnostic data as well as for instance energy data. Due to the similarity of the radio spectrum, Public GSM networks are used as fallback solution in case of outage. Of course, for this a roaming agreement with the PO is necessary In some cases, the Public Roaming is used as a temporary solution instead of GSM-R, or in the case of low traffic lines. In case of Public roaming, some functions like FN are available, but there is no REC.

• ETCS is the European Automatic Train Control System; GSM-R is the bearer of ETCS

• The GSM-R Network has to guarantee a high level of Quality of Service in order to fulfill the needs of ETCS.

• ETCS requires critical real time interactive data transfer;


ETCS Requirements

•ETCS is specified in the EU Directives, together with the GSM-R requirements•Tests have been done in Belgium, France, Germany, Italy, Netherlands, Switzerland, Spain, showing a general fulfillment of the requirements

Presenter

Presentation Notes

Connection establishment delay Value of elapsed time between the connection establishment request and the indication of successful connection establishment. The Connection establishment error ratio is defined as: Ratio of the number of unsuccessful connection establishment attempts to the total number of connection establishment attempts. The Connection loss rate is defined as: Number of connections released unintentionally per accumulated connection time. A transmission interference period TTI is the period during the data transmission phase of an existing connection in which, caused by the bearer service, no error-free transmission of user data units of 30 bytes is possible.

Implementation status in Europe

All European Railways having signed the MoU are in an implementation stage

Five networks are migrated to GSM-R: Germany, Italy, Netherlands, Norway and Sweden, which 47.700 km.

Presenter

Presentation Notes

As you can see on the map, all European railways are in an implementation stage, from feasibility study, to tendering or implementation. Five networks have finalized: the green ones. Denmark, Hungary, Portugal, Poland and Romania should have the tender this year – the Orange ones. Denmark has made the Radio Planning; Slovenia should have the tender next year. Austria, Belgium, Bulgaria, Czech Republic, Greece, Finland, France, Lithuania, Spain, UK, Switzerland are in implementation stage – the red ones. You will see in the next slides that GSM-R has crossed the point of no return for Europe; more than 50000 km are in operation. We can say that GSM-R is a proven system
