1. A User Equipment (UE) comprising:
transmission and reception circuitry;
a controller; and
a storage, wherein
in a case that the transmission and reception circuitry receives a control message including a first rejected Network Slice Selection Assistance information (NSSAI) including a Single Network Slice Selection Assistance information (S-NSSAI) and a rejection cause value associated with the S-NSSAI, and in a case that the rejection cause value indicates that the S-NSSAI is not available due to failed or revoked Network Slice-Specific Authentication and Authorization,
the controller stores, in the storage, the S-NSSAI into a second rejected NSSAI for failed or revoked Network Slice-Specific Authentication and Authorization, and
in a case that the UE enters state 5GMM-DEREGISTERED for the current Public Land Mobile Network (PLMN) on a 3GPP access and a non-3GPP access, the controller deletes the second rejected NSSAI in the storage.
