Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Railway Telecommunications
(RT).
Introduction
While the legacy architecture for a GSM-R network relies on the Rel-99 versions of the 3GPP/ETSI Technical
Specifications, the technical evolutions in the area of Core Network architecture led some railways operators to deploy
equipments based on the network architecture as described optionally in Rel-4 versions of the 3GPP/ETSI Technical
Specifications. This Technical Specification addresses the description of Rel-4 Core Network Architecture and interface
requirements for application on railway networks.
ETSI
6 ETSI TS 103 066 V1.1.1 (2011-10)
1 Scope
The present document describes the Rel-4 Core Network architecture as depicted in the Rel-4 version of the 3GPP/ETSI
Technical Specifications for application on railway networks in order to provide the ability for railway operators to
deploy a Rel-4 CN architecture, also known as Bearer Independent Core Network.
It then specifies the requirements on interfaces and procedures to operate such a Rel-4 Core Network architecture for
railway usage.
The present document does not mandate Rel-4 CN architecture to become the reference architecture for railways,
baseline for railway telecommunications remaining the Rel-99 version of the 3GPP/ETSI Technical Specifications.
Also the present document focuses on the changes from a Rel-99 to a Rel-4 CN architecture for the CS domain, as PS
domain equipments and interfaces are not affected by the deployment of BICN.
The present document is focussing on the requirements concerning the architecture and the interfaces only. It does not
take into consideration any other features or applications inserted into 3GPP/ETSI versions later than Rel-99.
