Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] see figure 1 , introduces the structure composition of the communication system supporting cross-network splitting of multimedia sessions in the present invention: wherein, the multimedia session splitting server at the core of control is based on IMS, that is, IP Multimedia System. As the core technology of the next-generation network, IMS fully considers the support for mobility, solves the problem of the integration of mobile and fixed networks, and introduces an important communication mode for differentiated services such as triple integration of voice, data, and video. The realization of the service shields the difference of the underlying network (including the telecommunication network, the Internet and the broadcasting network), and...

Abstract

The invention discloses a communication system and a communication method for supporting internetwork multimedia session splitting realization. The system comprises an IP multimedia subsystem (IMS)-based multimedia session splitting server, a circuit switched (CS) network, a packed switched (PS) network, various internet access networks, and a single-mode terminal and a multi-model terminal, wherein the CS network is connected to an IMS; the various internet access networks comprise WiFi, WiMAX and xDSL; the single-mode terminal and the multi-model terminal are connected to one or more of access networks; and the multimedia session splitting server is provided with a message transceiver module, a registration module, a decision-making module and a session splitting module. The invention also provides a method for splitting a multimedia session by using the system, and connecting the split multiple sessions to two or more terminals or different network interfaces of the same terminal. The communication system and the communication method realize the transmission of different media through the proper network thereof, so that the aims of effective network resource use, load balancing, connection reliability, service continuity, service transparency and the like are fulfilled, and the service fusion among different networks is realized.

Description

technical field [0001] The invention relates to a communication system and method supporting cross-network splitting of multimedia sessions, belonging 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 individualized multimedia service demands of many terminal customers at present. [0003] ICS (IMS Centralized Services) of IMS is a communication service based on the IMS mechanism...
