Non-homogeneous network slice

Abstract

Embodiments support non-homogeneous distribution of networks slices over a registration area (RA) in a manner that helps to ensure proper signaling of user equipment (UE) re-registration in cases of conditional network slices. For example, an RA is established to include conditional network slices that are available in only a subset of the tracking areas (TAs) of the RA. Each conditional network slice can be associated with a re-registration condition that explicitly or implicitly dictates whether the UE must re-register for that network slice prior to utilizing the network slice and upon entering a TA in the RA where the network slice is supported. For example, the re-registration condition can relate to whether the network slice is subject to Network Slice Admission Control (NSAC) and/or Network Slice Specific authentication & Authorization (NSSAA).
