Abstract
According to the disclosure, a communication method using a network slice by an access and mobility management function (AMF) comprises receiving one of subscribed single-network slice selection assistance information (S-NSSAI) or network slice selection policy (NSSP) information, requesting and receiving the other, non-received information of the subscribed S-NSSAI or the NSSP information, and transmitting a first message including the received subscribed S-NSSAI and the received NSSP information to a user equipment (UE).
Claims4
A method of a user equipment (UE), the method comprising:
- determining whether at least one single-network slice selection assistance information (S-NSSAI) in configured NSSAI stored in the UE is included in network slice selection policy (NSSP) information stored in the UE;
- transmitting, to an access and mobility management function (AMF), a policy provisioning request message including the NSSP information in response to the at least one S-NSSAI in the configured NSSAI being not included in the NSSP information;
- receiving, from the AMF, a response message including updated NSSP information as a response to the policy provisioning request message;
- and
- updating a policy of the UE based on the updated NSSP information included in the response message,
- wherein an update request message including the NSSP information is from the AMF to a policy control function (PCF) in response to the policy provisioning request message.
A user equipment (UE), the UE comprising:
- a transceiver;
- and
- at least one processor coupled with the transceiver, the at least one processor configured to:
- determine whether at least one single-network slice selection assistance information (S-NSSAI) in configured NSSAI stored in the UE is included in network slice selection policy (NSSP) information stored in the UE;
- transmit, to an access and mobility management function (AMF), a policy provisioning request message including the NSSP information in response to the at least one S-NSSAI in the configured NSSAI being not included in the NSSP information;
- receive, from the AMF, a response message including updated NSSP information as a response to the policy provisioning request message;
- and
- update a policy of the UE based on the updated NSSP information included in the response message,
- wherein an update request message including the NSSP information is from the AMF to a policy control function (PCF) in response to the policy provisioning request message.
