ETSI - TS 103 147
Railway Telecommunications (RT); GSM-R Core Network Redundancy
|Publication Date:||1 June 2013|
The present document describes the GSM-R Core Network Redundancy which is based on several features described in ETSI/3GPP Technical Specifications. In particular these features are:
- Intra-domain connection of RAN nodes to multiple CN nodes (RANflex).
- Coexistence of VGCS/VBS and RANflex.
- GCSMSC and GCR Redundancy for VGCS/VBS.
The present document is focussing on the relevant references needed for the GSM-R Core Network Redundancy. It does not describe the detailed requirements for the feature GSM-R Core Network Redundancy or the above listed subfeatures respectively as these are available in TS 143 068 [i.4], TS 143 069 [i.5], TS 129 002 [i.3] and TS 123 236 [i.6].
The minimum requirements on ETSI/3GPP for the use of GSM for application on railway networks are based on the Release 99 version of the Technical Specifications as described in EN 301 515 [i.1] plus a set of Change Requests as described in TS 102 281 [i.2]. The features forming the basis for GSM-R Core Network redundancy are described in releases later than Release 99. So the present document is referring to specifications versions later than Release 99 but is not mandating any other functionality than covered by the applicable 3GPP Work Items and referenced in the applicable paragraphs as listed in clauses 5.1.2, 5.2.2 and 5.3.2.
