1  ScopeWord‑p. 10
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.
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".

3.1  Terms

For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
5GMS System:
An assembly of Application Functions, Application Servers and interfaces from the 5G Media Streaming architecture that support either downlink media streaming services or uplink media streaming services, or both.
5GMS Application Provider:
A party that interacts with functions of the 5GMS System and supplies a 5GMS-Aware Application that interacts with functions of the 5GMS System.
5GMS-Aware Application:
Application in the UE, provided by the 5GMS Application Provider, that contains the service logic of the 5GMS application service, and interacts with other 5GMS Client and Network functions via the interfaces and APIs defined in the 5GMS architecture.
5GMS Client:
A UE function that is either a 5GMSd Client or a 5GMSu Client, or both.
5G Media Streaming Client for downlink (5GMSd Client):
UE function that includes at least a 5G Media Streaming Player and a Media Session Handler for downlink streaming and that may be accessed through well-defined interfaces/APIs.
5G Media Streaming Client for uplink (5GMSu Client):
Originator of 5GMSu service that may be accessed through well-defined interfaces/APIs.
5GMSu Media Streamer:
UE function that enables uplink delivery of streaming media content to an Application Server function of the 5GMS Application Provider, and which interacts with both the 5GMSu-Aware Application for media capture and subsequent streaming, and the Media Session Handler for media session control.
Dynamic policy:
A Dynamic PCC Rule (c.f. TS 23.503) for an uplink or downlink application flow during a media session.
Egest Session:
An uplink media streaming session from the 5GMSu AS towards the 5GMSu Application Provider.
Ingest Session:
A session to upload the media content into a 5GMSd AS.
Policy Template:
A collection of (semi-static) PCF/NEF API parameters which are specific to the 5GMS Application Provider and also the resulting PCC Rule.
Policy Template Id:
Identifies the desired policy template, which is used by 5GMSd AF to select the appropriate PCF/NEF API towards the 5G System so that the PCF can compile the desired PCC Rule.
Media Player Entry:
a document or a pointer to a document that defines a media presentation e.g. MPD for DASH content or URL to a video clip file.
Media Streamer Entry:
A pointer (e.g. in the form of a URL) that defines an entry point of an uplink media streaming session.
presentation entry:
A document or a pointer to a document that defines an application presentation e.g. an HTML5 document as defined in e.g. TS 26.307.
Provisioning Session:
a data structure supplied at interface M1d by a 5GMSd Application Provider that configures the 5GMSd features relevant to a set of 5GMSd-Aware Applications.
5GMSd Media Player:
UE function that enables playback and rendering of a media presentation based on a media player entry and exposing some basic controls such as play, pause, seek, stop to the 5GMSd-Aware Application.
Service Access Information:
Set of parameters and addresses (including 5GMSd AF and 5GMSd AS addresses), which are needed to activate the reception of a streaming session.
Service and Content Discovery:
Functionality and procedures provided by a 5GMSd Application Provider to a 5GMS-Aware Application that enables the end user to discover the available streaming service and content offerings and select a specific service or content item for access.
Service Announcement:
Procedures conducted between the 5GMS-Aware Application and the 5GMS Application Provider such that the 5GMS-Aware Application is able to obtain 5GMS Service Access Information, either directly or in the form of a reference to that information.
third party player:
Part of an application that uses APIs to exercise selected 5GMSd functions to play back media content.
third party uplink streamer:
Part of an application that uses APIs to exercise selected 5GMSu functions to capture and stream media content.
