5G Media Streaming (5GMS); General description and architecture
The present document specifies the 5G Media Streaming (5GMS) architecture. The 5GMS supported services include MNO and third-party Downlink Media Streaming Services, and MNO and third-party Uplink Media Streaming Services. The 5GMS architecture supports related network and UE functions and APIs, backwards compatible functions for EUTRAN deployments (with and without MBMS) and 5G specific features.
NOTE: Support of 5G Media Streaming over MBMS with 5GC is not considered in the current version of the present document.
The 5GMS architecture is functionally divided into independent components enabling different deployments with various degrees of integration between 5G MNOs and Content Providers. It is specified as a set of extensions to TS 23.501 "System Architecture for the 5G System".
Many of the features defined in this document are motivated by the conclusions of TR 26.804 [36].
