Terminal policy sending method, apparatus, and terminal policy sending system

A terminal policy sending system, comprising:

• a visited policy control function network element configured to:
• receive a first message from a home policy control function network element, wherein the first message comprises a first terminal policy and a second procedure transaction identity (PTI);
• send the first terminal policy and a first PTI to a mobility management network element;
• the mobility management network element configured to:
• receive the first terminal policy and the first PTI;
• send, to the visited policy control function network element, an execution result of the first terminal policy and the first PTI;
• and
• wherein the visited policy control function network element is further configured to:
• receive the execution result of the first terminal policy and the first PTI;
• determine, based on the first PTI, that the execution result is the execution result of the first terminal policy;
• and
• send a second message to the home policy control function network element, wherein the second message comprises the execution result and the second PTI.

A communications apparatus, comprising:

• at least one processor;
• and
• a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to:
• receive a first message from a home policy control function network element, wherein the first message comprises a first terminal policy and a second procedure transaction identity (PTI);
• send the first terminal policy and a first PTI to a mobility management network element;
• receive an execution result of the first terminal policy and the first PTI from the mobility management network element;
• determine, based on the first PTI, that the execution result is the execution result of the first terminal policy;
• and
• send a second message to the home policy control function network element, wherein the second message comprises the execution result and the second PTI.

A terminal policy sending method, comprising:

• receiving, by a visited policy control function network element, a first message from a home policy control function network element, wherein the first message comprises a first terminal policy and a second procedure transaction identity (PTI);
• sending, by the visited policy control function network element, the first terminal policy and a first PTI to a mobility management network element, wherein the first PTI is allocated by the visited policy control function network element for the first terminal policy;
• receiving, by the visited policy control function network element, an execution result of the first terminal policy and the first PTI from the mobility management network element;
• determining, by the visited policy control function network element based on the first PTI, that the execution result is the execution result of the first terminal policy;
• and
• sending, by the visited policy control function network element, a second message to the home policy control function network element, wherein the second message comprises the execution result and the second PTI and the second PTI.
