IMS networks and methods are disclosed for providing online charging for supplementary services for a session. The IMS network includes an application server operable to provide at least one supplementary service for a session. When the supplementary service is to be provided, the session is routed to the application server. The application server then provides the supplementary service and also provides charging for the service. To provide charging, the application server generates one or more charging request messages for the supplementary service, and transmits the charging request message for the supplementary service to an online charging system (OCS) of the IMS network. The OCS processes the charging request message accordingly to provide charging for the supplementary service in addition to the session. |
