Research And Implementation Of Multi-media Color Ring-video System Terminal Software Based On Windows Mobile

Today,3G technologies are developing rapidly. After studying the mobile value-added services, reference to the successful application of CRBT, this paper gives an implementation of Multimedia Color Ring-Video business which is combination of mobile communications and Internet.The Multimedia Color Ring-Video business is that, when the caller is making a phone to the called, before the call is connected, each one on the phone has been pushing a defined multimedia color ring-video to each other, and that is a video file. At present, Windows Mobile platform is a smart phone platform which occupies a dominant market position and has good prospects. Therefore, the main contents of this paper are based on Windows Mobile platform the terminal software of multimedia color ring-video business, including its design ideas and implementation of process.This paper has introduced the concept of mobile value-added services and domestic and international situation, also introduced the research significance and market prospects of the multimedia color ring-video business. At the same time, has done a brief introduction of the popular smart phone platform Windows Mobile, including its history, version history, platform architecture. After the careful study of the logic function of multimedia color ring-video business, got a specific implementation, which includes introduction to MVC architecture, the application of User Datagram Protocol (UDP) in the process of video push, decomposition of platform capabilities about Multi-media Color Ring-video System Terminal Software and the signaling processes which are supported by the smart phones. At the same time, the main business issues and solutions of video push and business custom which are two main modules of Multimedia Color Ring-Video are described and the video push, play and business custom, cancellation, user register, login and some other key functions are implemented.Finally, this paper do list the terminal software design, development and maintenance errors encountered and the corresponding solutions, at the same time, do point out the deficiencies of the platform and the need for further improvements, which as the foundation for later study.
