1  Scope  p. 7

The present document specifies the architecture for real-time media communication. To support MNO and third-party services for real-time media, it is specified the essential functionalities and interfaces. The primary scope of this Technical Specification is the documentation of the following aspects:
  • A real-time media communication architecture mapped to the 5GS architecture and any SA2 stage 2 architecture additions, with relevant core building blocks, reference point, and interfaces to support modern operator and third-party media services, based on the 5GMS architecture
  • Provide all relevant reference points and interfaces to support different collaboration scenarios between 5G System operator and third-party media communication service provider, including but not limited to an AR media communication service provider.
  • Call flows and procedures for different real-time communication service types,
  • Specify support for AR relevant functionalities such as split-rendering or spatial computing on top of a 5G System based on this architecture.
