A method for implementing controlled charging includes: a message routing apparatus receives a service message sent by a first telecom service open gateway when the first telecom service open gateway determines that the service charged party is not in the service area of the first charging system which is the home charging system of the first telecom service open gateway; the message routing apparatus sends the service message to a second telecom service open gateway which is the home telecom service open gateway of the service charged party, where the service message instructs the second telecom service open gateway which is the home telecom service open gateway of the service charged party to send a charging request to a second charging system which is the home charging system of the second telecom service open gateway. The present invention also discloses a system, a message routing apparatus and a telecom service open gateway for implementing controlled charging. With the present invention, telecom service open gateways are deployed in different areas of the network and interconnected via a message routing apparatus so as to enable inter-area charging while the simplicity of networking and the efficiency of routing are also assured. |
