The Design And Implementation Of Terminal System Based On IMS

As the development of communications and information technology application, telecommunications business need are changing to the convergence of fixed phone and mobile phone, and the combination of integrated information service of voice and Internet applications. The traditional operators providers are facing the highly competition with the Internet application providers. Currently, QQ, MSN and other instant messaging tools can only communicate on the Internet, and the fetion, moble phone and other tools can only send text messages or make call. It is mainly because the field of telecommunications and Internet communications applications are not really integrated.IMS (IP Multimedia Subsystem) as the core control technology of next generation network, is causing a widespread concern in the industry, it is a new form of multimedia services that can meet the end of the terminate client and more innovative, more diverse Multimedia services. Currently, IMS is considered to be the core technology of next generation networks as well as mobile and fixed network convergence solution, and the introduction of voice, data and video is an important way of convergence business.The purpose and significance of the research is to design and implement a terminal system based on IMS technology, and make the PSTN (Public Switched Telephone Network) and data network, general phone and PC application together, can achieve presence, instant messaging, voice services, video services to supply rich IP multimedia applications and meet the personalized entertainment and multimedia communications.
