23.2283GPPIP Multimedia Subsystem (IMS)Release 18Stage 2TS

4.10.0 General

This clause describes architectural concepts to fulfil the requirements for IMS Group Management described in TS 22.250 [32].

4.10.1 IMS group administration

The capabilities required for IMS group management are defined in clause 5.4 of TS 22.250 [32]. The Ut reference point is used to manage groups from the UE. This does not preclude the use of other mechanisms for group management, e.g. using OSA or OA&M mechanisms; the details of these other mechanisms are out of scope of this document.

The Ut reference point shall support a scenario where one single Application Server is used to create groups that can be utilized for different services, possibly hosted by different ASs.

NOTE: Such an Application Server is sometimes referred to as a Group and List Management Server (GLMS).

4.10.2 Group identifiers

Each group shall be addressable by a globally unique group identifier. The group identifier shall take the form of a Public Service Identifier.
