Abstract
Detailed behaviors of a UE and a network are clarified in order to efficiently support temporally restricted NSs. A UE transmits a registration request message including information indicating support for a temporary network slice, receives a registration accept message or a registration reject message including allowed NSSAI or configured NSSAI including S-NSSAI indicating the temporary network slice, and a timer value corresponding to the S-NSSAI, starts a timer using the timer value, stores the S-NSSAI in allowed NSSAI or configured NSSAI in the UE, and, in a case that the timer expires, removes the S-NSSAI from the allowed NSSAI or the configured NSSAI in the UE, and stores the S-NSSAI in rejected NSSAI in the UE.

(canceled)
A User Equipment (UE) comprising:
- transmission and reception circuitry;
- a controller;
- and
- storage circuitry, wherein
- the storage circuitry is storing:
- a first Single Network Slice Selection Assistance Information (S-NSSAI);
- and
- first control information related to a time period when a network slice identified by the first S-NSSAI is available,
- wherein the first S-NSSAI is an S-NSSAI included in a configured Network Slice Selection Assistance Information (NSSAI) stored in the storage circuitry, and
- in a case that the transmission and reception circuitry received a configuration update command message, the configuration update command message including the first S-NSSAI and second control information related to a time period when a network slice identified by the first S-NSSAI is available, the controller is configured to:
- update the first control information stored in the storage circuitry to the second control information, and
- remove the first S-NSSAI from the configured NSSAI stored in the storage circuitry, based on the second control information.
A User Equipment (UE) comprising:
- transmission and reception circuitry;
- a controller;
- and
- storage circuitry, wherein
- the storage circuitry is storing:

- and
- remove the first S-NSSAI from the configured NSSAI stored in the storage circuitry, based on the second control information.
A communication control method performed by a User Equipment (UE), the communication control method comprising:
- storing:
- a first Single Network Slice Selection Assistance Information (S-NSSAI);
- and
- first control information related to a time period when a network slice identified by
