Embodiment Construction

[0031] 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.

[0032] see figure 1, introduces the structure composition of the communication system that supports cross-network and cross-terminal multimedia session merging in the present invention: wherein, the multimedia session merging server as the control center is based on IMS, ie 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 implementation of the service shields the differences of the underlying network (including the telecommunication network, the Internet and the broadcasting network), and can p...

Abstract

The invention relates to a communication system and a method supporting cross-network and cross-terminal realization of multimedia session merging, and the system is provided with an IMS-based multimedia session merging server, a CS network accessed into an IMS, a PS network and various Internet access networks including WiFi, WiMAX and xDSL, as well as a plurality of single-mode terminals and / ormulti-mode terminals connected with various networks, wherein the multimedia session merging server is provided with a message transmitting and receiving module, a registration module, a decision-making module and a session merging module. The invention further provides a method for merging multimedia sessions which are respectively established in the different networks and connected with different network interfaces into one multimedia session by adopting the system, thereby leading a plurality of the network interfaces of one terminal or the plurality of the network interfaces of the plurality of terminals in the sessions to be capable of being simultaneously connected with an opposite terminal for establishing the multimedia session, further achieving the purposes of effective utilization of network resources, load balance, connection reliability, service continuity and business transparency and the like and further realizing the business integration of the different network.

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. [0003] ICS (IMS Centralized Services) of IMS is a communication s...
