Study on security enhancements for 5G multicast-broadcast services phase 2
The present document is to identify key issues, potential security and privacy requirements and solutions with respect to enhancement for 5G multicast-broadcast services. Specifically:
- Study the security enhancement enabling UE's receiving Multicast MBS Session data in RRC Inactive state. Analysis whether existing security mechanisms for UE in RRC connected state can be reused or new security enhancement are needed.
- Study the security impact and potential enhancement if supporting feasible and efficient resource utilization for the same broadcast content to be provided to 5G MOCN network sharing scenarios.
- Other security issues if identified.
