full_form: Network Slice Selection Assistance Information
context: Authentication and Authorisation in the UE context and sends the UE Configuration Update message to revoke the S-NSSAI from the current Allowed NSSAI, for any Access Type for which NSSAA had been successfully run on this S-NSSAI. The AMF provides a new Allowed NSSAI to the UE by removing the S-NSSAI for which authorization has been revoked. The AMF provides new rejected NSSAIs to the UE including the S-NSSAI for which authorization has been revoked. If no S-NSSAI is left in Allowed NSSAI for an access after the revocation, and a Default NSSAI exists that requires no NSSAA or for which a NSSAA did not previously fail over this access, then the AMF may provide a new Allowed NSSAI to the UE containing the Default NSSAI. If no S-NSSAI is left in Allowed NSSAI for an access after the revocation, and no Default NSSAI can be provided to the UE in the Allowed NSSAI or a previous NSSAA failed for the Default NSSAI over this access, then the AMF shall execute the Network-initiated
description: NSSAI stands for Network Slice Selection Assistance Information. It is a parameter used in the context of network slicing to assist in the selection of appropriate network slices for user equipment (UE). The NSSAI contains information that helps the UE and the network to determine which network slice to use for a particular service or application.
explanation: The provided context from 3GPP TS 33.501, section 16.5, highlights the role of NSSAI in network slice selection and authorization revocation processes. This indicates that NSSAI is a critical parameter used in network operations, thus classifying it as a Parameter.
