Abstract: IMS gateway systems and methods are disclosed for providing online charging in an IMS network. A call control system of the IMS gateway system receives a message from a CSCF for a call session. The call control system identifies an OCS routing address from the message, and identifies a corresponding OCS routing address from the subscriber database. The call control system compares the OCS routing address from the message with the OCS routing address from the subscriber database. If the two OCS routing addresses match, then the call control system validates the OCS routing address from the message and/or the subscriber database, and transmits a charging request to the appropriate OCS based on the validated OCS routing address. If the two OCS routing addresses do not match, then the call control system transmits a charging request to the appropriate OCS based on the OCS routing address from the subscriber database.
