For both passengers and freight railway operations, mobile communication applications have become mission-

23、critical. In its strategy to create a single, interoperable railway market in Europe, the European Commission adopted GSM based radio systems (GSM-R) as the mandatory train-to-track radio communication technology for services that are considered mission-critical and safety related. These services ar

24、e conventional voice services (driver-controller calls, railway emergency calls, group calls, etc.) and data services for ERTMS/ETCS signalling systems. The implementation and use of the current GSM-R system by the European railways is still expanding. As per the EU Regulation 2016/919 i.2 and ECC D

25、ecision (02)05 i.12, all current GSM-R networks in Europe use 876 - 880 MHz for the train-to-ground link and 921 - 925 MHz for the ground-to-train link. GSM-R thus has been granted a EU harmonised frequency band, the UIC frequency band. In addition to this, the band 873 - 876 MHz paired with 918 - 9

26、21 MHz has also been identified for GSM-R use on a national basis. New, updated or renewed trains are being equipped with radio equipment supporting this extended band. GSM-R is facing a number of challenges: 1) There is a need to plan the end of life of the system, with current committed vendor sup

27、port ending 2030. 2) On the mid-term, in more and more areas, additional capacity will be required to support railway operations, in part related to the increasing implementation of ETCS. In parallel to the implementation of the successor to GSM-R (hereinafter called Future Railway Mobile Communicat

28、ion System - FRMCS), the GSM-R system needs continued operation to allow the upgrade of all rolling stock, until this technology is end-of-life and decommissioned. ETSI ETSI TR 103 333 V1.1.1 (2017-02) 6 Therefore the Union Internationale des Chemins de Fer (UIC), the European Union Agency for Railw

29、ays, the GSM-R industry and other railway stakeholders across Europe are defining and specifying the next generation radio solution for railway operations, in close cooperation with ETSI. This will additionally result in an update of the EU legal framework in order to guarantee railway interoperabil

30、ity. The approach for FRMCS taken in the present document is based on the following principles: 1) Separation of railway applications from the underlying network technologies, creating more flexibility, such as possible usage of different radio access technologies on different line categories (even

31、within a country). 2) The new radio system is to be based upon the 3GPP technology roadmap. 3) For cost efficiency and migration purposes, the reuse of existing assets (radio sites, spectrum) is favoured. In the present document, the following spectrum options have been explored: Use of the existing

32、 harmonised railway spectrum in the 2 x 4 MHz UIC frequency band (876 - 880 MHz / 921 - 925 MHz); Use of a combination of these 2 x 4 MHz plus 2 x 3 MHz, called the E-UIC frequency band, resulting in a total of 2 x 7 MHz (873 - 880 MHz / 918 - 925 MHz). In order to calculate the amount of radio spec

33、trum needed to fulfil the railway requirements, the present document has assumed the use of the latest 3GPP RAT. It is anticipated that the spectral efficiency of future 4G/5G RAT operating in the 900 MHz range, may improve as compared to current technologies. Coexistence studies will need to be per

34、formed with regard to the impact of such future radio access technologies. In order to determine the amount of spectrum needed for FRMCS, a traffic model has been used, with several combinations of usage scenarios and operational conditions. Based on the investigations made in the present document,

35、the following conclusions are drawn: Railways need 2 x 7 MHz of dedicated spectrum to accommodate the current and (partially) future Critical railway applications and usages for the coming decades, taking into account the need for parallel operation of GSM-R and the successor technologies during the

36、 migration from GSM-R to the successor system. For additional railways applications (performance and business), other solutions such as sharing with other stakeholders (e.g. PPDR) and/or using MFCN, are anticipated. From economic efficiency perspective, using spectrum in the 900 MHz band is preferre

37、d, based on reuse of the existing GSM-R radio sites. Usage of the 700 MHz or 400 MHz ranges would lead to less reuse and/or re-location of existing sites. Furthermore, in the 700 MHz and 400 MHz range no possibility appears to exist for spectrum dedicated to railways. Usage of the 2 x 4 MHz spectrum

38、 for railways in 876 - 880 MHz / 921 - 925 MHz is not sufficient, extension with the 2 x 3 MHz in the 873 - 876 MHz / 918 - 921 MHz band, which has already been requested for railways in the ETSI TR 102 627 i.7, is necessary. The introduction of FRMCS necessitates the harmonisation of the 873 - 876

39、MHz / 918 - 921 MHz band. Although the preferred solution for the migration period is to use 2 x 3 MHz in addition to the current 2 x 4 MHz, other carrier widths may be considered depending on spectrum availability in member states. Although the 900 MHz frequency band is preferred, other frequency b

40、ands may be considered depending on availability in member states, whilst ensuring the technical and economic viability. This spectrum needs to be identified by 2020, made available for trials per 2022, and available for operational deployment as of 2023. Decisions about spectrum allocation for rail

41、ways have to be published in time, in order to be included in the 3GPP specifications and to allow the timely preparation for inclusion in the legal framework of railway interoperability. The above conclusions result in the following requests: ECC is requested to harmonise the 873 - 880 MHz UL / 918

42、 - 925 MHz DL band for railway purposes. ETSI ETSI TR 103 333 V1.1.1 (2017-02) 7 ECC is requested to allow the use of other radio technologies than GSM in this band. ECC is requested to undertake the necessary coexistence studies. In addition to this, 3GPP would have to add this band to the list of

43、the 3GPP operating bands, possibly enhance some radio parameters and specify railway-related functions. Introduction The present document was developed by ETSI TC RT NG2R to support the cooperation between ETSI and the Electronic Communications Committee (ECC) of the European Conference of Post and

44、Telecommunications Administrations (CEPT). It is intended to describe the spectrum requirements for a European system for operational railway communications between a terrestrial ground network and a train, based on 4G/5G technology, and operating in the band 873 - 880 MHz paired with 918 - 925 MHz,

45、 in coexistence with the already deployed GSM-R technology. ETSI ETSI TR 103 333 V1.1.1 (2017-02) 8 1 Scope The present document applies to the next generation radio communication system for railway operations, intended to replace GSM-R, and hereafter referred to as Future Railway Mobile Communicati

46、on System (FRMCS),which may require a change of the present frequency designation within CEPT and of the present regulatory framework for the proposed band(s). The preferred regulatory approach for FRMCS is to reuse the same frequency bands that are currently designated for railway operations, withi

47、n the 873 - 880 MHz paired with 918 - 925 MHz frequency band. The present document, in particular: gives a GSM-R market overview; provides some technical information; investigates the harmonised UIC frequency band currently used for GSM-R, 876 - 880 MHz UL / 921 - 925 MHz DL, as well as the E-UIC fr

48、equency band, 873 - 880 MHz UL / 918 - 925 MHz DL for critical railways communications; notes the regulatory issues in order to ensure a smooth introduction of FRMCS as well as an efficient use of spectrum. The FRMCS is used for communication between trains, portable UE and trackside communication e

49、ntities, for applications directly related to railway operation.
