Abstract

A User Equipment (UE) includes a transmission and reception unit, a controller, and a storage unit. The transmission and reception unit receives allowed Network Slice Selection Assistance Information (NSSAI). In a case that the UE is roaming, the controller deletes mapped Single Network Slice Selection Assistance Information (S-NSSAI) of the allowed NSSAI from pending NSSAI stored by the storage unit.

Claims (11)

1 . A User Equipment (UE) comprising:

a transmission and reception unit, a controller, and a storage unit, wherein

the transmission and reception unit receives allowed Network Slice Selection Assistance Information (NSSAI), and

the controller:

deletes Single Network Slice Selection Assistance Information (S-NSSAI) of the allowed NSSAI from pending NSSAI stored by the storage unit, and

in a case that the UE is roaming, deletes mapped S-NSSAI of the allowed NSSAI from the pending NSSAI stored by the storage unit, wherein

the pending NSSAI indicates S-NSSAI for which a network slice-specific authentication and authorization procedure is pending.

2 . A communication control method performed by a User Equipment (UE), the communication control method comprising:

receiving allowed Network Slice Selection Assistance Information (NSSAI);

deleting Single Network Slice Selection Assistance Information (S-NSSAI) of the allowed NSSAI from pending NSSAI stored by the storage unit; and

in a case that the UE is roaming, deleting mapped S-NSSAI of the allowed NSSAI from the pending NSSAI stored by the UE, the pending NSSAI indicating S-NSSAI for which a network slice-specific authentication and authorization procedure is pending.
