A.1 Scope of signalling flows

24.2923GPPIP Multimedia (IM) Core Network (CN) subsystem Centralized Services (ICS)Release 17Stage 3TS

This annex includes signalling flows for ICS which provide examples of ICS specific behaviour. Therefore, signalling flows that would otherwise be identical to examples of normal behaviour without ICS are not included in this annex.

In many cases, the signalling flows in this annex expand on the overview information flows provided in 3GPP TS 23.292 [6].
