Design And Implementation And Validation Of Web IM Based On RCS

With the growing of Inetnet networks, Instance Message System nowadays has taken an important roll in everyday life communications. Having real time ability, platform-crossing, IM has been the most importance tool on the Internet.This paper introduces RCS of telecommunication service. RCS is an solution based on IMS network struct, making it possible that terminates between different countries, differecnt operators communicate free. And study on the instant message service based RCS, which owns the standard of SIMPLE IM, and summaries the protocol mode and instant message mode.This paper also studies on the solutions of Web instant message system, including Flash XML Socket method, Java Applet Socket and "Server Push" method based on HTTP long connection. Comparing the mothods, select the "Server Push" method to be the solution of this paper, and introduce the details of Ajax using in Web instant message system.The design of RCS instant message model is an application of opening telecom network enabler.On the basis of RCS IM protocol and OneAPI, we design a IM web server using web technologies. This paper shows the probability and the work flow of instant message service, and implements the server and client side of the system. Terminates on the Internet can communicate via this system. And it also offers the function for registering and adding and deleting freinds. With the help of software testing theory, this paper also tests the function of the project.Finally, it summaries the instant message technology of RCS, and describes the future of IM based on RCS.
