Method for configuring user equipment policy, network device and terminal device thereof

1. A policy configuration method, comprising:

receiving, by a terminal equipment, a user equipment (UE) policy sent by a network equipment, wherein the UE policy is applied to a non-public network (NPN network),

wherein receiving by a terminal equipment, a UE policy sent by a network equipment, further comprises: receiving, by the terminal equipment, the UE policy sent by the network equipment while registered to the non-public network; and applying, by the terminal equipment, the UE policy to the non-public network,

characterized in that, the method further comprises: carrying a Policy Section Identity (PSI) corresponding to the UE policy of the non-public network in a container of a registration request message in a case that the terminal equipment initiates a registration request in the non-public network,

storing the UE policy in association with an identifier of the non-public network, wherein the identifier of the non-public network is Public Land Mobile Network Identifier (PLMN ID)+Network Identifier (NID).

2. The method of claim 1 , wherein the UE policy received by the UE while registered to the NPN is considered by default by the UE as being only suitable for the NPN network.

3. The method of claim 1 , further comprising:

not carrying the PSI corresponding to the UE policy of the non-public network in the container of the registration request message in a case that the registration request is initiated in other networks.

4. The method of claim 3 , wherein the PSI is a PSI corresponding to the UE policy used in the NPN network.

5. The method of claim 1 , wherein the UE policy comprises an Access Network Discovery Selection Policy (ANDSP), a User Equipment Routing Selection Policy (URSP), a Vehicle-to-Everything (V2X) policy and a Uu interface policy.

6. The method of claim 1 , wherein the NPN network is a Stand-alone NPN (SNPN).

7. The method of claim 1 , wherein the PSI comprises the PLMN ID and a Policy Section Code (PSC).

8. A terminal equipment, comprising:

a transceiver configured to receive a user equipment (UE) policy sent by a network equipment, wherein the UE policy is applied to a non-public network (NPN network),

wherein the transceiver of the terminal equipment is configured to receive the UE policy sent by the network equipment, while registered to the non-public network;

and wherein the terminal equipment further comprises: a processor configured to apply the UE policy to the non-public network,

characterized in that, the transceiver is configured to carry a Policy Section Identity (PSI) corresponding to the UE policy of the non-public network in a container of a registration request message in a case that a registration request is initiated in the non-public network,

the processor is configured to store the UE policy in association with an identifier of the non-public network, wherein the identifier of the non-public network is Public Land Mobile Network Identifier (PLMN ID)+Network Identifier (NID).

9. The terminal equipment of claim 8 , wherein the UE policy received by the terminal equipment while registered to the NPN is considered by default by the UE as being only suitable for the NPN network.

10. The terminal equipment of claim 8 , wherein the transceiver is configured to not carry the PSI corresponding to the UE policy of the non-public network in the container of a registration request message in a case that a registration request is initiated in other networks.

11. The terminal equipment of claim 10 , wherein the PSI is a PSI corresponding to the UE policy used in the NPN network.

12. The terminal equipment of claim 8 , wherein the UE policy comprises an Access Network Discovery Selection Policy (ANDSP), a User Equipment Routing Selection Policy (URSP), a Vehicle-to-Everything (V2X) policy and a Uu interface policy.

13. The terminal equipment of claim 8 , wherein the NPN network is a Stand-alone NPN (SNPN).

14. A network equipment, comprising:

a transceiver, configured to send a user equipment (UE) policy to a terminal equipment, wherein the UE policy is applied to a non-public network (NPN network),

characterized in that, the transceiver is configured to receive a fifth indication carried in a container of a registration request message sent by the terminal equipment, wherein the fifth indication is configured to indicate a network type registered by the terminal equipment, and the network type comprises the non-public network or a public network; and send a UE policy corresponding to the network type to the terminal equipment.

the UE policy is stored in association with an identifier of the non-public network, wherein the identifier of the non-public network is Public Land Mobile Network Identifier (PLMN ID)+Network Identifier (NID).

15. The network equipment of claim 14 , wherein the transceiver is configured to send the UE policy to the terminal equipment according to the network type.

16. The network equipment of claim 15 , wherein the UE policy sent by the network equipment is considered by default as being only suitable for the NPN network.

17. The network equipment of claim 14 , wherein a policy identifier of the UE policy sent to the terminal equipment is a Policy Section Identity (PSI).

18. The network equipment of claim 17 , wherein the PSI is a PSI corresponding to the UE policy used in the NPN.

19. The network equipment of claim 14 , wherein the UE policy comprises an Access Network Discovery Selection Policy (ANDSP), a User Equipment Routing Selection Policy (URSP), a Vehicle-to-Everything (V2X) policy and a Uu interface policy.

20. The network equipment of claim 14 , wherein the NPN network is a Stand-alone NPN (SNPN).
