Abstract
An AMF node () manages a UE context regarding a UE (). The UE context includes a) a set of allowed network slice identifiers indicating one or more network slice identifiers currently allowed to the UE (), and b) a set of pending network slice identifiers indicating one or more network slice identifiers for which a Network Slice-Specific Authentication and Authorization (NSSAA) procedure is pending. If the AMF () triggers initiation of a re-authentication and re-authorization procedure for a first network slice identifier currently allowed to the UE (), it removes the first network slice identifier from the allowed set and store the same in the pending set. This, for example, allows the AMF to manage the UE context appropriately.
