23.2053GPPBearer-independent circuit-switched core networkRelease 17Stage 2TS

The UMTS to GSM handover to a third MSC server (from MSC-B server to MSC‑B server) is the combination of the two previous inter-MSC handover cases:

– for MSC-B server a subsequent UMTS to GSM handover from MSC-B server back to MSC-A server as described in clause 8.2.3; and

– for MSC-B server a basic UMTS to GSM handover from MSC-A server to MSC‑B server as described in clause 8.2.2.

MSC-A server implements the corresponding parts of each handover case; i.e. access handling in MSC-A server is not included.
