IMS-related TS/TR
This TS defines the service requirements from users' and operators' perspective for the support of IP multimedia applications through the IMS.

IP multimedia applications are supported by IP multimedia sessions in the IM CN Subsystem. IP multimedia sessions use IP connectivity bearers (e.g. GPRS as a bearer). Examples of IP multimedia applications include speech communication, real time multimedia applications, shared online whiteboards etc.
