The Design And Implementation Of Data Conference In IMS Multimedia Conference

With the development of communication networks, communication services are continuously updated and developed. Currently communication service is moving to the IP-based, multimedia-oriented, integration-based and mobile-oriented direction. Users are no longer satisfied with traditional voice services and low-speed data services, more and more multimedia services and high-speed data services combined with image, voice and data are needed. In the R5 version of the 3GPP, IP Multimedia Subsystem (IMS) which is proposed for the future of multimedia services provides a common service platform, which is an important step in implementing the real IP network services. In the IMS network, users can use the rich multimedia services and high-speed data services.IMS multimedia conference is a new type of service which is based on IMS network. It integrates video and audio conference, data collaboration function. Multi-party video conference allowes users to communicate through video; audio conference allows users to interact through the mobile terminal; data collaboration allows users to log on to the conference with PC terminals, operate the instant messages, PPT sharing, whiteboard and file upload. Data collaboration allows users to create, manage, end, join and leave the conference.Rich Internet Application (RIA) is a new kind of application witch is running on a traditional browser. RIA has quickly responding and strongly interacting functions which are the advantages of desktop applications, and the characteristics that Web applications are widely and easily spread. Flex is an enterprise-class solution of RIA in the view layer. It has been widely used because its rich component library and extensive media support features. Flex can flexibly integrate with J2EE in the development of applications, data collaboration conference system development is based on the integration of Flex and J2EE.
