Charging System Switching Method and Apparatus

摘要

A charging system switching method and an apparatus such that an online charging system or a customer relationship management system may initiate charging system switching of a specific service, and may switch any service from an original charging system to a new charging system in real time, without switching all users on the original charging system onto the new charging system. Therefore, a smooth switching between multiple charging systems is supported, and in addition, multiple charging systems may perform charging for different services of a same user, thereby implementing coexistence of different charging systems.

主权项

1. A charging system switching method, comprising:
determining, by an online charging system (OCS), a service for which a charging system needs to be switched, and a target charging system to which the service needs to be switched; constructing, by the OCS, a re-authentication request external session message, wherein the re-authentication request external session message comprises a first identifier and a second identifier, wherein the first identifier is used to indicate the service for which the charging system needs to be switched, and wherein the second identifier is used to indicate the target charging system to which the service needs to be switched; and sending, by the OCS, the re-authentication request external session message to an access device in order to instruct the access device to switch the service from a current charging system to the target charging system according to the re-authentication request external session message.
