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).

First claim

What is claimed is:

1 . A method of a user equipment (UE) using a network slice, the method comprising:
transmitting, to an access and mobility management function (AMF), a policy request message; receiving, from the AMF, a response message including policy information; and updating a policy of the UE based on the policy information included in the response message.

2 . The method of claim 1 , wherein the policy request message includes information indicating a request for network slice selection policy (NSSP) information.

3 . The method of claim 2 , wherein the policy request message includes version information of NSSP information stored in the UE.

4 . The method of claim 1 , wherein the policy information included in the response message is obtained from a policy control function (PCF).

5 . The method of claim 4 , wherein the policy information included in the response message includes NSSP information obtained from the PCF.

6 . A method of an access and mobility management function (AMF) using a network slice, the method comprising:
receiving, from a user equipment (UE), a policy request message; transmitting, to a policy control function (PCF), a request message including the received policy request message; receiving, from the PCF, a first response message including a policy information related to the UE; and transmitting, to the UE, a second response message including the policy information related to the UE.

7 . The method of claim 6 , wherein the policy request message includes information indicating a request for network slice selection policy (NSSP) information.

8 . The method of claim 7 , wherein the policy request message includes version information of NSSP information stored in the UE.

9 . The method of claim 6 , wherein the policy information includes NSSP information related to the UE.

10 . A user equipment (UE), the UE comprising:
a transceiver; and at least one processor, coupled with the transceiver, and configured to:
transmit, to an access and mobility management function (AMF), a policy request message;
receive, from the AMF, a response message including policy information; and
update a policy of the UE based on the policy information included in the response message.

11 . The UE of claim 10 , wherein the policy request message includes information indicating a request for network slice selection policy (NSSP) information.

12 . The UE of claim 11 , wherein the policy request message includes version information of NSSP information stored in the UE.

13 . The UE of claim 10 , wherein the policy information included in the response message is obtained from a policy control function (PCF).

14 . The UE of claim 13 , wherein the policy information included in the response message includes NSSP information obtained from the PCF.

15 . An apparatus for an access and mobility management function (AMF) using a network slice, the apparatus comprising:
a transceiver; and at least one processor, coupled with the transceiver, and configured to:
receive, from a user equipment (UE), a policy request message;
transmit, to a policy control function (PCF), a request message including the received policy request message;
receive, from the PCF, a first response message including a policy information related to the UE; and
transmit, to the UE, a second response message including the policy information related to the UE.

16 . The apparatus of claim 15 , wherein the policy request message includes information indicating a request for network slice selection policy (NSSP) information.

17 . The apparatus of claim 16 , wherein the policy request message includes version information of NSSP information stored in the UE.

18 . The apparatus of claim 15 , wherein the policy information includes NSSP information related to the UE.
