Abstract
The present invention provides a ubiquitous solution for providing charge-related voice service such as voice announcement and interactive voice response in an IP multimedia subsystem. In particularly, an online charging system (10) detects the subscriber account profile of a user terminal (51) to determine whether there is an event for providing an end user with voice announcement or interactive voice response (S203). If there is such voice announcement event or interactive voice response event, the online charging system (10) will enter “redirection state” and send an instruction (S204) to an online charging client (20) for instructing the online charging client (20) to redirect the user terminal to a first server (30) for providing voice announcement or interactive voice response such that the first server (30) provides the user terminal (51) with voice announcement or interactive voice response. The online charging client (20) may comprise network gateway, session initiation protocol application server or media resource function controller, etc.
