Charging processing method and system, and related device

A charging method, performed by a charging processing device, wherein the method comprises:

• receiving a first charging request message for a user service from a charging trigger device, wherein the first charging request message comprises at least one of first charging data or first information of the user service;
• and
• performing charging processing on the user service based on the first charging request message;
• wherein
• the first charging data comprises charging data that is not sent or charging data that is not processed because a charging processing device for the user service was unavailable, wherein the charging data that is not sent is charging data that is not sent by the charging trigger device to any charging processing device, and the charging data that is not processed is charging data for which the charging trigger device does not receive a charging processing result from a charging processing device;
• and
• the first information indicates that a reason for reporting the first charging request message is that a charging processing device for the user service transitioned to “available”.

A charging processing device, comprising at least one processor and a memory, wherein

• the memory is configured to store a program, and wherein the program, when executed by the at least one processor, causes the charging processing device to:
• receive a first charging request message for a user service from a charging trigger device, wherein the first charging request message comprises at least one of first charging data or first information of the user service;
• and
• perform charging processing on the user service based on the first charging request message;
• wherein
• the first charging data comprises charging data that is not sent or charging data that is not processed because a charging processing device for the user service was unavailable, wherein the charging data that is not sent is charging data that is not sent by the charging trigger device to any charging processing device, and the charging data that is not processed is charging data for which the charging trigger device does not receive a charging processing result from a charging processing device;
• and
• the first information indicates that a reason for reporting the first charging request message is that a charging processing device for the user service transitioned to “available”.

A computer-readable storage medium, wherein the computer-readable storage medium comprises a computer program or instructions, and when the computer program or the instructions are run on a computer, the communication method is performed as following:

• receive a first charging request message for a user service from a charging trigger device, wherein the first charging request message comprises at least one of first charging data or first information of the user service;
• and
• perform charging processing on the user service based on the first charging request message;
• wherein the first charging data comprises charging data that is not sent or charging data that is not processed because a charging processing device for the user service was unavailable, wherein the charging data that is not sent is charging data that is not sent by the charging trigger device to any charging processing device, and the charging data that is not processed is charging data for which the charging trigger device does not receive a charging processing result from a charging processing device;
• and
• the first information indicates that a reason for reporting the first charging request message is that a charging processing device for the user service transitioned to “available”.
