Abstract
To clarify handling of rejected S-NSSAI that is rejected in a certain tracking area in a certain registration area and that is available in another tracking area in the registration area, behaviors of a UE and an NW for the rejected S-NSSAI, and the like. In a case that, in rejected NSSAI for a current tracking area in the UE, S-NSSAI is stored that is not available in the current tracking area in a current registration area and that is available in another tracking area in the current registration area, and the UE receives new allowed NSSAI for a current PLMN or SNPN, S-NSSAI included in the allowed NSSAI is deleted from the rejected NSSAI for the current tracking area in the UE.

(canceled)
A User Equipment (UE) comprising:
- transmission and reception circuitry;
- controlling circuitry;
- and
- storage circuitry,
- wherein
- in a case that the transmission and reception circuitry receives a first NSSAI (Network Slice Selection Assistance Information), the controlling circuitry is configured to store the first NSSAI in the storage circuitry,
- the first NSSAI contains one or more S-NSSAIs (Single Network Slice Selection Assistance Information) not available in partial tracking area(s) in a registration area,
- each of the one or more S-NSSAIs is associated with one or more tracking areas where the S-NSSAI is not available, and
- in a case that the UE is in the tracking area where the S-NSSAI is not available, the transmission and reception circuitry is configured not to transmit a registration request message including a requested NSSAI including the S-NSSAI.
A communication control method performed by a User Equipment (UE), the communication control method comprising:
- in a case that the UE receives a first NSSAI (Network Slice Selection Assistance Information), storing the first NSSAI in the UE,
- wherein
- the first NSSAI contains one or more S-NSSAIs (Single Network Slice Selection Assistance Information) not available in partial tracking area(s) in a registration area,
- each of the one or more S-NSSAIs is associated with one or more tracking areas where the S-NSSAI is not available, and
- in a case that the UE is in the tracking area where the S-NSSAI is not available, the UE does not transmit a registration request message including a requested NSSAI including the S-NSSAI.
