Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Railway Telecommuni
17、cations (RT). Introduction Railway undertakings are facing the challenge to evolve their networks to support the ETCS operation in high density railway traffic areas. The limited GSM-R spectrum resources put additional pressure on air interface traffic capabilities and as well radio spectrum efficie
18、ncy. Also, the continuous development of further voice services e.g. GSM-R based shunting communication using circuit switched technology requires increased traffic resource capabilities. When ETCS is using circuit switched data mode, radio traffic channel capacity utilization is low compared to the
19、 requested/assigned bandwidth. Having more than one ETCS session multiplexed to one radio resource using packet switched mode is therefore desirable. Taking into account GSM evolution GPRS/EGPRS bearer services provide packet oriented data transmission that allocates transmission resources on demand
20、 and release those resources if no further data are to be exchanged. ETCS message sizes are rather small and the typical message frequency are in the range of several seconds. This allows to multiplex several ETCS sessions to one transmission resource and facilitating use of ETCS level 2 in high den
21、sity rail traffic areas. The present document identifies the features required to allow the support of ETCS using GPRS/EGPRS bearer services, in particular the basic ones and those needed to fulfil End-to-End performance requirements. ETSI ETSI TS 103 328 V1.2.1 (2016-10)5 1 Scope The present docume
22、nt defines the minimum set of 3GPP GPRS features to support ETCS application and to guarantee QoS required. Two operational cases are applicable in GSM-R networks: GSM-R GPRS packet switched bearer service is only utilized by ETCS PS-mode operation - ETCS only operation. GSM-R GPRS packet switched b
23、earer service is utilized by simultaneous ETCS and other packet data oriented applications - Simultaneous operation of ETCS and non-ETCS applications. Both operational scenarios require basic GPRS features but in case of simultaneous ETCS and non-ETCS operation, ETCS packet data session requires pri
24、ority over non-ETCS packet data traffic. The present document is focussing on the relevant references needed for the GSM-R PS-domain. It does not describe the detailed requirements for each of the referred GSM feature. The minimum requirements on ETSI/3GPP for the use of GSM for application on railw
25、ay networks are based on the Release 99 version of the Technical Specifications and are described in ETSI EN 301 515 i.1. The features serving as the basis for GSM-R PS-domain are described in releases later than Release 99. So the present document is referring to specifications versions later than
26、Release 4 but is not mandating any other functionality than covered by the applicable 3GPP Work Items and referenced in the applicable clauses as listed in clauses 5.1.10 and 5.2.2. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition
