Description

technical field

[0001] The invention relates to a communication system and method supporting cross-network and cross-terminal realization of multimedia session merging, and belongs to the technical field of communication. Background technique

[0002] IP Multimedia System IMS (IP Multimedia Subsystem) is a session control system based on the Session Initiation Protocol SIP. The IMS system uses the SIP protocol as the signaling for call control and service control, and uses the IP network as the core network. Mobile access, and the access method is not limited to the cellular radio frequency interface, and can also be wireless WLAN or wired LAN, DSL and other technologies. The terminal of the IMS system may be a mobile phone terminal, a fixed phone terminal, a multimedia terminal or a PC, etc. IMS can meet the newer and more personalized multimedia service requirements of many terminal customers at present.
