Abstract
IMS gateway systems and methods are disclosed for providing budget control in an IMS network. IMS networks allow for media changes (e.g., audio to audio/video) during an IMS session. An IMS gateway system described herein receives a session control message (e.g., SIP INVITE message) responsive to the media change during the session. The IMS gateway system identifies media information for the new media in the session control message. The IMS gateway system generates a corresponding charging request message, and includes media information for the new media in the charging request message. The IMS gateway system then transmits the charging request message to an online charging system (OCS) to provide for charging of the session based on the new media for the session.
