Abstract

The present disclosure relates to a policy determining method, a network device, and a storage medium. The policy determining method is executed by a network device, and includes: obtaining a plurality of policy requests for one or more terminals in a terminal group; and determining a first policy request among the plurality of policy requests, the first policy request being configured to update a policy of the terminal group.

First claim

What is claimed is:

1. A policy determining method, comprising:
receiving, by a policy control function (PCF), information of a first priority associated with a policy, wherein the policy is a policy of a terminal group and each policy of the terminal group corresponds to one respective first priority;
determining, by the PCF based on subscription information, a second priority associated with a terminal in the terminal group, wherein each terminal in the terminal group corresponds to a respective second priority;
obtaining, by the PCF, a plurality of policy update requests sent by an application function (AF), wherein the plurality of policy update requests comprise one or more policy requests for the terminal group;
obtaining, by the PCF, one or more policy authorization requests sent by another PCF, the one or more policy authorization requests comprising one or more policy requests for the terminal in the terminal group, wherein the one or more policy requests are determined by the another PCF; and
determining, by the PCF based on the first priority and the second priority, a first policy request among the one or more policy requests for the terminal group obtained by the PCF and the one or more policy requests for the terminal in the terminal group determined by the another PCF, wherein the first policy request is configured to update the policy of the terminal group.

2. The policy determining method according to claim 1 , further comprising:
sending, by the PCF, a response message to a policy authorization request, wherein the response message to the policy authorization request comprises the first policy request.

3. The policy determining method according to claim 2 , further comprising:
updating, by the PCF, the policy of the terminal group based on the first policy request.

4. A policy control function (PCF), comprising:
a processor;
a memory for storing instructions executable by the processor;
wherein the processor is configured to perform acts comprising:
receiving information of a first priority associated with a policy, wherein the policy is a policy of a terminal group and each policy of the terminal group corresponds to one respective first priority;
determining, based on subscription information, a second priority associated with a terminal in the terminal group, wherein each terminal in the terminal group corresponds to a respective second priority:
obtaining a plurality of policy update requests sent by an application function (AF), wherein the plurality of policy update requests comprise one or more policy requests for the terminal group;
obtaining one or more policy authorization requests sent by another PCF, the one or more policy authorization requests comprising one or more policy requests for the terminal in the terminal group, wherein the one or more policy requests are determined by the another PCF; and
determining, based on the first priority and the second priority, a first policy request among the one or more policy requests for the terminal group obtained by the PCF and the one or more policy requests for the terminal in the terminal group determined by the another PCF, wherein the first policy request is configured to update the policy of the terminal group.

5. The PCF according to claim 4 , wherein the processor is further configured to perform acts comprising:
sending a response message to a policy authorization request, wherein the response message to the policy authorization request comprises the first policy request.

6. The PCF according to claim 5 , wherein the processor is further configured to perform acts comprising:
updating the policy of the terminal group based on the first policy request.

7. A non-transitory computer readable storage medium, having stored thereon instruction, wherein the instructions are executed by a processor of a policy control function (PCF), enabling the PCF to perform acts comprising:
receiving information of a first priority associated with a policy, wherein the policy is a policy of a terminal group and each policy of the terminal group corresponds to one respective first priority;
determining, based on subscription information, a second priority associated with a terminal in the terminal group, wherein each terminal in the terminal group corresponds to a respective second priority;
obtaining a plurality of policy update requests sent by an application function (AF), wherein the plurality of policy update requests comprise one or more policy requests for the terminal group;
obtaining one or more policy authorization requests sent by another PCF, the one or more policy authorization requests comprising one or more policy requests for the terminal in the terminal group, wherein the one or more policy requests are determined by the another PCF; and
determining, based on the first priority and the second priority, a first policy request among the one or more policy requests for the terminal group obtained by the PCF and the one or more policy requests for the terminal in the terminal group determined by the another PCF, wherein the first policy request is configured to update the policy of the terminal group.

8. The non-transitory computer readable storage medium according to claim 7 , wherein the PCF is further enabled to perform acts comprising:
sending a response message to a policy authorization request, wherein the response message to the policy authorization request comprises the first policy request.

9. The non-transitory computer readable storage medium according to claim 7 , wherein the PCF is further enabled to perform acts comprising:
updating the policy of the terminal group based on the first policy request.
