Abstract

The disclosed IMS gateway system (200) allowing media change during IMS dialogue responds to the media change, receives dialogue control information (such as SIP INVITE information) to recognize the media information of new media and generate corresponding charge request information contained the media information, and sends the request information to an OCS (220) for charging the dialogue.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to IMS budget control for processing online charging for media changes during an IMS session. Background technique [0002] As stated by the Third Generation Partnership (3GPP), the IP Multimedia Subsystem (IMS) provides a public core network with a network-agnostic network architecture for convergent networks. Service providers are accepting this architecture in the evolution of next-generation networks. The IMS architecture was originally defined by 3GPP to provide multimedia services to mobile users via an Internet Protocol (IP) network. The IP network has become the lowest cost bearer network for transmitting video, voice and data. IMS uses the advantages of IP networks to provide multimedia services to IMS users on the IMS platform. The signaling used in the IMS network is the Session Initiation Protocol (SIP). IMS defines the standard SIP interface between application serv...
