Abstract
A method for selecting a network slice admission control function (NSACF). The method includes selecting the NSACF for a network slice based on service area information of the NSACF.
Claims14
A method for selecting a network slice admission control function (NSACF), performed by a network device, comprising:
- during a user equipment (UE) registration procedure, selecting the NSACF for a network slice based on service area information of the NSACF, wherein a registration request message from a UE carries single network slice selection assistance information (S-NSSAI) and a UE identifier;
- sending a first request message to a selected NSACF, wherein the first request message comprises the S-NSSAI, the UE identifier, and an update flag, and the update flag instructs to increase a number of registered UEs;
- receiving a first response message from the selected NSACE;
- returning a registration accept message to the UE in a case where the first response message indicates that the number of registered UEs does not reach a maximum number;
- and
- returning a registration reject message to the UE in a case where the first response message indicates that the number of registered UEs reaches the maximum number.

A communication apparatus, comprising:
- a transceiver;
- a memory;
- and a processor, wherein the processor respectively connects to the transceiver and the memory, and is configured to execute computer-executable instructions stored on the memory to control reception and transmission of a wireless signal by the transceiver and implement the following operation:
- during a user equipment (UE) registration procedure, selecting a network slice admission control function (NSACF) for a network slice based on service area information of the NSACF, wherein a registration request message from a UE carries single network slice selection assistance information (S-NSSAI) and a UE identifier;
- sending a first request message to a selected NSACF, wherein the first request message comprises the S-NSSAI, the UE identifier, and an update flag, and the update flag instructs to increase a number of registered UEs;
- receiving a first response message from the selected NSACE;
- returning a registration accept message to the UE in a case where the first response message indicates that the number of registered UEs does not reach a maximum number;
- and
- returning a registration reject message to the UE in a case where the first response message indicates that the number of registered UEs reaches the maximum number.

A non-transitory computer-readable storage medium storing computer-executable instructions thereon, wherein when the computer-executable instructions are executed by a processor, the processor is configured to:
- during a user equipment (UE) registration procedure, select a network slice admission control function (NSACF) for a network slice based on service area information of the NSACF, wherein a registration request message from a UE carries single network slice selection assistance information (S-NSSAI) and a UE identifier;
- sending a first request message to a selected NSACF, wherein the first request message comprises the S-NSSAI, the UE identifier, and an update flag, and the update flag instructs to increase a number of registered UEs;
- receiving a first response message from the selected NSACF;
- returning a registration accept message to the UE in a case where the first response message indicates that the number of registered UEs does not reach a maximum number;
- and
- returning a registration reject message to the UE in a case where the first response message indicates that the number of registered UEs reaches the maximum number.
