Abstract
In response to revocation of authorization of a first network slice identifier for a User Equipment (UE) (), an Access and Mobility Management Function (AMF) node () initiates a release procedure to release a PDU session associated with the first network slice identifier. This makes it possible, for example, to properly manage a Protocol Data Unit (PDU) session associated with a network slice when authorization for that network slice is revoked.
