Network Slicing Extensions for 5G media services
The present document identifies standardization needs and potential standards gaps relevant to media streaming while using 5G network slicing. In specific, the following aspects are addressed in this document:
- To identify relevant use cases that can be addressed using network slicing, and study collaboration scenarios and deployment architectures to support network slicing for media services.
- To identify any missing provisioning aspects for configuring media services with one or more network slices including QoS configuration, reporting and dynamic policy.
- To identify impact of network slicing on dynamic policy invocation APIs, including selection of appropriate network slices for dynamic policy requests, possible migration of UE application traffic flows between network slices due to dynamic policy procedures, discovery of dynamic policy AF, and necessary routing considerations.
- To determine the need and describe methods for AF-to-AF communication to support interoperability if 5GMS AF instances from different vendors are deployed in the same 5GMS System.
- To identify methods for deploying, supporting, and resolving slice-specific 5GMS AS instances.
- To identify potential areas for normative work and communicate/align with SA2 as well as other potential 3GPP WGs (SA5, SA6) on relevant aspects related to the study.
