NETWORK SLICE AUTHENTICATION FOR DEFAULT SLICES

Abstract:

A method for wireless communication performed by a user equipment (UE) includes determining whether a network slice-specific authentication and authorization (NSSAA) procedure is complete. The method also includes transmitting a protocol data unit (PDU) session request to attempt establishing a PDU session without providing an Single-NSSAI when the NSSAA procedure is complete. A method for wireless communications, by an access and mobility management function (AMF) includes determining whether all default network slices for a user equipment (UE) are subject to network slice-specific authentication and authorization (NSSAA). The method also initiates NSSAA on the default network slices when all default network slices are subject to NSSAA.
