[FS_AMD_Ph2] AF requested modification of set of Network Slice(s) for a UE
Proposal 1: The use cases and collaboration scenarios for network slicing documented in clauses 5.3 and 5.4 respectively be included in an informative annex to TS 26.501 [20].
Proposal 2: The changes to the PolicyTemplate resource data model definition described in clause 6.1.2.1 be implemented in TS 26.510 [42] to support Policy Template provisioning for a plurality of Network Slices and/or Data Networks, and the corresponding alignment changes described in clause 6.1.3 be implemented in TS 26.501 [20].
Proposal 3: The Key Issue description and corresponding candidate solution on bootstrapping application invocation on a Network Slice documented in clause 6.7 of the present document be included as an informative clause or annex to TS 26.501 [20] as guidance for implementations.
Proposal 4: To support the procedure for AF-requested modification of Network Slice(s) for a UE, the following are adopted into media delivery specifications as described in clause 6.X.3 of the present document:
a. In stage-2 specification TS 26.501 [20], update of domain model for dynamic policies to illustrate provisioning of Alternate S-NSSAI, and the procedures for Dynamic Policy based on Network Slicing, for both downlink and uplink streaming
b. In state-3 specification TS 26.512 [21], add procedure descriptions for M6d and M6u for the 5GMSd/5GMSu Aware Application requesting the Media Session Handler for change of traffic treatment
c. In stage-3 specification TS 26.510 [42], update the PolicyTemplate and DynamicPolicy resource data models, and the Dynamic Policy provisioning and invocation interactions to enable AF-requested modification of Network Slice(s) of a UE
