Abstract
Although a UE is not storing allowed NSSAI for the current PLMN or SNPN, configured NSSAI for the current PLMN or SNPN, and/or default configured NSSAI, in a case that the UE is storing the partially allowed NSSAI and is in a TA in which S-NSSAI included in the partially allowed NSSAI is supported, the UE includes the S-NSSAI in requested NSSAI in a registration request message.
Claims5
A user equipment (UE) comprising:
- transmission and reception circuitry;
- a controller;
- and
- storage circuitry,
- wherein:
- in a case that the UE supports a partial network slice, the transmission and reception circuitry is configured to transmit a registration request message including capability information indicating support for the partial network slice;
- and
- in a case that the transmission and reception circuitry receives a Single Network Slice Selection Assistance Information (S-NSSAI) included in a first Network Slice Selection Assistance Information (NSSAI) included in a registration accept message or a configuration update command message, the controller is configured to store the S-NSSAI included in the first NSSAI in the storage circuitry,
- wherein:
- the first NSSAI includes one or more S-NSSAIs that are not available in some tracking areas in a registration area,
- each S-NSSAI is associated with one or more tracking areas in which the S-NSSAI is not available, and
- the controller is configured to delete the S-NSSAI and a list of the tracking areas from the storage circuitry after the UE moves out of the registration area.

A communication control method performed by a User Equipment (UE), the communication control method comprising:
- in a case that the UE supports a partial network slice, transmitting a registration request message including capability information indicating support for the partial network slice;
- and
- in a case that the UE receives a Single Network Slice Selection Assistance Information (S-NSSAI) included in a first Network Slice Selection Assistance Information (NSSAI) included in a registration accept message or a configuration update command message, storing the S-NSSAI included in the first NSSAI in the UE,
- wherein:
- the first NSSAI includes one or more S-NSSAIs that are not available in some tracking areas in a registration area,
- each S-NSSAI is associated with one or more tracking areas in which the S-NSSAI is not available, and
- the UE deletes the S-NSSAI and a list of the tracking areas from the UE after the UE moves out of the registration area.
