Study on enhanced access to and support of network slices
The present document studies various use cases and scenarios using network slices, in order to identify potential service requirements for the 5G system, e.g.:
- when there is a restriction of network slice to e.g., certain frequency bands/sub bands, RATs, geographical areas, networks and applications,
- when a UE has a subscription to multiple network slices and these network slices are deployed for e.g., different frequency bands/sub bands, RATs, geographical area and applications,
- when there is a preference or prioritization for a network slice over other network slices e.g. when there are conflicting constraints on network slice availability.
The present document also includes a gap analysis of its derived potential requirements versus existing 3GPP requirements.
