1  ScopeWord‑p. 6

The present document aims to develop high-level use cases and identify the related potential requirements to enable IMS to support new real time communication services.
IMS enhancements for the following scenarios are studied in this document:
  • one to many communication (e.g. live broadcast video service in a stadium, concert, etc.) with efficient media negotiation;
  • interworking for a UE to communicate with non-sip devices (e.g. camera), and delivery of information to control functions of the non-sip devices (e.g. PTZ);
  • fast IMS call setup time for Group Communication;
  • enhancements on voice & video communications for supporting AR/VR;
  • network slicing for IMS;
  • service visibility and usage;.
  • services using AI (voiceprint) in RTC.
