6.2 Preparing for uplink media streaming p. 185

6.2.1 Introduction p. 185

Before streaming media data in the uplink direction, a set of parameters are provisioned at the 5GMSu AF/AS and at the 5GMSu Client. On the 5GMSu AF/AS, the M1u API is used for session provisioning. On the UE side, the M8u or M5u API is used for provisioning.

6.2.2.1 Domain model |R18| p. 185

The M1u baseline domain model is depicted in Figure 6.2.2.1-1 overleaf. It consists of a Provisioning Session, which contains at least one of the following:

A Content Publishing Configuration,
A Policy Template,
One or more Content Preparation Templates,
An Edge Resources Configuration specifying the requirements for edge processing as defined in TS 23.548 and TS 23.558 in support of the Provisioning Session, including eligibility criteria that indicate the circumstances in which edge computing is to be used for Media Streaming sessions associated with this Provisioning Session and parameters indicating the tolerance of the application for relocation of the Edge AS, or

Each Provisioning Session is uniquely identified within the 5GMS System by a Provisioning Session identifier.

When a certain 5GMS feature (such as content publishing configuration, policy template, content preparation template or edge resource configuration) is selected, the 5GMSu AF compiles the resulting Service Access Information that the 5GMSu Client needs to have to access the services via M5u.

The M3u baseline domain model used by the 5GMSu AF to configure Content Publishing in the 5GMSu AS is depicted in Figure 6.2.2.1-2 below. It comprises a set of Content Publishing Configurations, each containing one or more Contribution Configurations and one Publishing Configuration. A Contribution Configuration may reference Server Certificates for presentation at reference point M4u and/or Content Preparation Templates specifying media manipulation by the 5GMSu AS between media contribution at reference point M2u and media egest at reference point M4u.
