Relevant specifications for 5GMS AF

[dsilhavy]

5G Core

• TS 23.501 - Technical Specification Group Services and System Aspects; System architecture for the 5G System (Release 17) clause 6.2.10 (and, for NRF registration clause 6.2.6, clause 6.3, clause 7.1.5).

5G Media Streaming

• TS 26.501 - 5G Media Streaming (5GMS); General description and architecture (Release 17)
• TS 26.512 - 5G Media Streaming (5GMS); Protocols (Release 17) clause 4.3, clause 4.5, clause 4.7, clause 6, clause 7, clause 9, clause 11.

Note that new versions of the 5G Media Streaming specifications will be published shortly after SA#97, which ends on 16th September. In particular, a number of corrections to the OpenAPI definitions have been made in TS 26.512 annex C, so this version would be a sensible baseline starting point.

We may also consider Release 16 specifications as a point of departure. Release 16 specifies a subset of 5G Media Streaming features that fully satisfies the scope of MVP#1 and MVP#2. The corrections to TS 26.512 annex C relevant to Release 16 will also be published following SA#97, so again this version would be a sensible baseline starting point.

I'm confused. I think 23.501 should be related to 5G Core and 26.501 be 5GMS above. And NRF should be NEF (when not trusted by the operator)? I've tried to go step by step here: Link We can grow it from there.

Good spot, @jordijoangimenez. TS 23.501 and TS 26.501 were the wrong way round above. I have fixed.

[jordijoangimenez]

We need to shift the clauses too. I'll fix. Would e.g. clause 11 be something to be looked from an MSH point of view or from AF? MSH will use what's described in clause 11 to access resources exposed by AF. I would cover the MSH API under the "Relevant specifications for 5GMS MSH"... but no strong view if we want to have the link here too

You're right that the 5GMS AF needs to implement Service Access Information, so yes: TS 26.512 clause 11 is relevant.
