ETSI TS 123 236

ETSI TS 123 236 covers the details for the Intra Domain Connection of RAN Nodes to Multiple CN Nodes for GERANand UTRAN based systems. In particular, it details the impacts to GSM and UMTS systems and the stage 2 proceduresfor the support of connecting a RNC or BSC to multiple MSC servers or SGSNs. The overall solution is described, andthe detailed impacts on the existing specifications are identified. The description of a broadly similar concept for EUTRANbased systems is not described in the document: instead, it is described in TS 23.401 [22].

NOTE: The specified solution impacts RAN nodes. In case an upgrade of radio networks is not performed, thesolutions for deploying NNSF functionality above RAN nodes described in TR 23.924 [23] may be usedas a guideline for connecting RAN nodes to multiple MSC servers.

The reference model to which these procedures apply can be found within TS 23.002 [1]. Detailed architecturalrequirements within the subsystems are contained within the remainder of the 23 series of specifications e.g. therequirements for the Packet Switched (PS) domain are contained within TS 23.060 [2] and the requirements for theBearer Independent CS Core Network are contained in TS 23.205 [14].
