## Abstract

The present disclosure provides a method and a device for determining and sending a policy, and provides a specific method for a terminal device to use a user equipment (UE) policy. Said method includes: a terminal device determining, according to first information, a UE policy used by the terminal device, the first information including at least one piece of the following information: an area where the terminal device is located, a public land mobile network (PLMN) identity (ID) corresponding to the network in which the terminal device is registered or resides, and a usage duration of the UE policy.

## Claims

### Claim 1

A method for determining a policy, comprising:
determining, by a terminal device, a user equipment (UE) policy used by the terminal device according to first information, wherein the first information comprises at least one piece of following information: an area where the terminal device is located, a public land mobile network (PLMN) identity (ID) corresponding to a network selected by the terminal device, and a usage duration of the UE policy;
wherein a UE policy corresponding to a first PLMN received by the terminal device is applicable to an equivalent PLMN of the first PLMN;
using, by the terminal device, the UE policy corresponding to the first PLMN, wherein the first PLMN and a target PLMN are equivalent PLMNs, and the target PLMN is a PLMN corresponding to the network where the terminal device registered or camped;
wherein using, by the terminal device, the UE policy corresponding to the first PLMN, comprises:
using, by the terminal device, the UE policy corresponding to the first PLMN under at least one of following situations: the terminal device does not have a UE policy corresponding to the target PLMN, and the UE policy corresponding to the first PLMN is the last updated UE policy; and
wherein
if there is a UE policy corresponding to the target PLMN in the terminal device, the terminal device uses the UE policy corresponding to the target PLMN as a target UE policy;
if the UE policy corresponding to the first PLMN is the last updated UE policy, the terminal device uses the UE policy corresponding to the first PLMN as the target UE policy; and
if there is no UE policy corresponding to the target PLMN in the terminal device, and the UE policy corresponding to the first PLMN is the last updated UE policy, then the terminal device uses the UE policy corresponding to the first PLMN as the target UE policy.

### Claim 2 (depends on 1)

The method of claim 1, wherein the PLMN ID corresponding to the network selected by the terminal device is a PLMN ID corresponding to a network where the terminal device registered or camped on.

### Claim 3 (depends on 1)

The method of claim 1, wherein the equivalent PLMN comes from a core network, in a terminal registration process, the core network element AMF sends the equivalent PLMN list and/or a precedence of the equivalent PLMN list to the terminal device.

### Claim 4 (depends on 1)

The method of claim 1, wherein the UE policy corresponding to the first PLMN received by the terminal device is applicable to another PLMN contained within a registration area or a tracking area identity (TAI) list area where the terminal device is located.

### Claim 5 (depends on 1)

The method of claim 1, wherein the method further comprises:
using, by the terminal device, the UE policy corresponding to the first PLMN, under a situation that the terminal device moves from the first PLMN to a PLMN equivalent to the first PLMN.

### Claim 6 (depends on 1)

The method of claim 1, wherein the UE policy used by the terminal device comprises at least one of following: a wireless local area network (WLAN) selection policy, a UE route selection policy, a vehicle to everything policy, an Access Network Discovery and selection Policy (ANDSP).

### Claim 7

A terminal device, comprising: a processor and a memory, wherein the memory is configured to store a computer program and the processor is configured to call and run the computer program stored in the memory to determine a user equipment (UE) policy used by the terminal device according to first information, wherein the first information comprises at least one piece of following information: an area where the terminal device is located, a public land mobile network (PLMN) identity (ID) corresponding to a network selected by the terminal device, and a usage duration of the UE policy
wherein a UE policy corresponding to a first PLMN received by the terminal device is applicable to an equivalent PLMN of the first PLMN;
use the UE policy corresponding to the first PLMN, wherein the first PLMN and a target PLMN are equivalent PLMNs, and the target PLMN is a PLMN corresponding to the network where the terminal device registered or camped;
use the UE policy corresponding to the first PLMN under at least one of following situations: the terminal device does not have a UE policy corresponding to the target PLMN, and the UE policy corresponding to the first PLMN is a last updated UE policy;
wherein
if there is a UE policy corresponding to the target PLMN in the terminal device, the terminal device uses the UE policy corresponding to the target PLMN as a target UE policy;
if the UE policy corresponding to the first PLMN is the last updated UE policy, the terminal device uses the UE policy corresponding to the first PLMN as the target UE policy; and
if there is no UE policy corresponding to the target PLMN in the terminal device, and the UE policy corresponding to the first PLMN is the last updated UE policy, then the terminal device uses the UE policy corresponding to the first PLMN as the target UE policy.

### Claim 8 (depends on 7)

The terminal device of claim 7, wherein the PLMN ID corresponding to the network selected by the terminal device is a PLMN ID corresponding to a network where the terminal device registered or camped on.

### Claim 9 (depends on 7)

The terminal device of claim 7, wherein the equivalent PLMN comes from a core network, in a terminal registration process, the core network element AMF sends the equivalent PLMN list and/or a precedence of the equivalent PLMN list to the terminal device.

### Claim 10 (depends on 7)

The terminal device of claim 7, wherein the UE policy corresponding to the first PLMN received by the terminal device is applicable to another PLMN contained within a registration area or tracking area identity (TAI) list area where the terminal device is located.

### Claim 11 (depends on 7)

The terminal device of claim 7, wherein the processor is configured to call and run the computer program stored in the memory to:
use the UE policy corresponding to the first PLMN, under a situation that the terminal device moves from the first PLMN to a PLMN equivalent to the first PLMN.

### Claim 12 (depends on 7)

The terminal device of claim 7, wherein the UE policy used by the terminal device comprises at least one of following: a wireless local area network (WLAN) selection policy, a UE route selection policy, a vehicle to everything policy, an Access Network Discovery and selection Policy (ANDSP).
