Content for TR 33.886 Word version: 18.1.0
1 Scope p. 6
The present document identifies key security issues, potential security and privacy requirements and solutions with respect to network slicing Phase 3 work. Specifically,
- It studies potential security impact/requirements/solutions (e.g. Steering of Roaming) to support the HPLMN to provide a roaming UE the VPLMN slice information in a secure manner.
- It studies potential security impact/requirements/solutions to support temporary slices, slice service areas mismatched with Tracking Area (TA) boundaries, and slices where Network Slice Selection Assistance Information (NSSAI) are not available in some TAs of a Registration Areas (RA).
- It studies potential security impact/requirements/solutions to support secured Network Slice Admission Control (NSAC) procedures in the cases of NSAC for multiple service areas and network controlled UE behaviours.
