Research And Data Services Based On Cdma Fixed Wireless

With the rapid development of high-speed and wireless net, which supported by LianTong and YiDong corporation, mobile data service tends to play an important part in our daily lives. As we know, the development of mobile data service , not only bring us the continual spread and change , which make effect on the chain of mobile communication industry, but also promote the co-operation of each department on this industry chain. At the same time, mobile communication terminal is the most important to the mobile data service. Without powerful support of mobile terminal, mobile data service can not develop well.All the principles and designs in this paper , are based on the project of CDMA wireless communication terminal in Pakistan. From the designment and implementation of three reprentation data services, we would like to solve data service on the mobile terminal, in order to show how to use principles and model in project implementation, how to realize the software of data service on mobile terminal.The main contents are as follows. Firstly, detail develop condition of mobile data service are introduced, and the principles and plat of data service are analysed, include the creation and call of process, the priority of tasks, the application interface, and the event-handle mechanism. Secondly, detail designment and implementation of data service software are shown. Finally, system test results show us the effect and some problems.Through the paper, we can find that, the research of data service software is successfully. It also concluded that, the development of mobile data service is based on user demands. We need try our best to provide people the data service, which is more speediness, more steady, more powerful.
