Abstract
By introducing a concept such as an equivalent SNPN, mobility can be improved, service continuity can be improved, NSSAI can be appropriately managed, and an equivalent SNPN list can be appropriately managed. In a case that roaming is not performed and a UE receives a new allowed NSSAI for a current SNPN, the UE deletes one or more S-NSSAIs included in a new allowed NSSAI for the current SNPN and/or its equivalent SNPN from a pending NSSAI stored in the UE.
Claims4
A User Equipment (UE) comprising:
- transmission and reception circuitry;
- storage circuitry;
- and
- controlling circuitry,
- wherein the transmission and reception circuitry is configured to transmit a registration request message including information indicating that the UE supports an equivalent Stand-alone Non-Public Network (SNPN) in a registration procedure, and
- the controlling circuitry is configured to delete an equivalent SNPN list stored in the storage circuitry, in a case that a registration accept message that does not contain an equivalent SNPN list has been received in the registration procedure.
A User Equipment (UE) comprising:
- transmission and reception circuitry;
- storage circuitry;
- and
- controlling circuitry,
- wherein
- in a case that roaming is not performed, and in a case that the transmission and reception circuitry receives new allowed Network Slice Selection Assistance Information (NSSAI) for a current Stand-alone Non-Public Network (SNPN), the controlling circuitry is configured to delete one or more Single Network Slice Selection Assistance Information (S-NSSAIs) included in a new allowed NSSAI for the current SNPN and/or an equivalent SNPN of the current SNPN from a pending NSSAI stored in the storage circuitry.
A communication control method performed by a User Equipment (UE), the communication control method comprising:
- transmitting a registration request message including information indicating that the UE supports an equivalent Stand-alone Non-Public Network (SNPN) in a registration procedure;
- and
- deleting an equivalent SNPN list stored in the UE, in a case that a registration accept message that does not contain an equivalent SNPN list has been received in the registration procedure.
