Method for managing roaming charging configuration parameter, system, and related device

A method for managing a roaming charging configuration parameter, applied to a charging processing device, wherein the charging processing device is configured to perform charging processing on a roaming data connection session based on a request of a charging trigger device, the roaming data connection session is a data connection session between roaming user equipment and a data network, and the roaming user equipment is user equipment roaming from a home network to a visited network, and the method comprises:

• generating, by the charging processing device, first roaming charging configuration parameter management information, wherein the first roaming charging configuration parameter management information comprises a first roaming charging configuration parameter group that is to be activated after the roaming data connection session is established, the first roaming charging configuration parameter group comprises at least one roaming charging configuration parameter, and the roaming charging configuration parameter is a configuration parameter related to a collection operation and/or a reporting operation of roaming charging information of the roaming data connection session;
• and
• sending, by the charging processing device, the first roaming charging configuration parameter management information to the charging trigger device.

A computer program product comprising instructions stored on a non-transitory medium that, when executed by a processor, cause an apparatus to:

• generating first roaming charging configuration parameter management information, wherein the first roaming charging configuration parameter management information comprises a first roaming charging configuration parameter group that is to be activated after the roaming data connection session is established, the first roaming charging configuration parameter group comprises at least one roaming charging configuration parameter, and the roaming charging configuration parameter is a configuration parameter related to a collection operation and/or a reporting operation of roaming charging information of the roaming data connection session;
• and
• sending the first roaming charging configuration parameter management information to the charging trigger device.
