Design and Implementation of Document-Sharing Based on IMS

IMS is the subsystem proposed by 3GPP which supplies IP multimedia services, meeting the trend of integrating of communication networks. The common function of an IMS terminal includes data communication (instant message),multimedia communication (video and audio calling) and presence. Document-sharing application is based on the whiteboard application, of course, it is a bright spot of whiteboard features, the combination of them are increasingly affected by the companies and enterprises. As it is of great significance for the multimedia conferencing, and its simple operating and intuitive using, help enhance its competitiveness of the feature function. With XMPP stack, a solution is adopted to share office document between IMS terminals for the implementation of Instant Communicating System for Education Network, we design and implement the module of office document sharing in an IMS terminal. The result of test shows that it works well.
