The Study And Implementation Of China Mobile OTA Server System Structure

Along with the development of Mobile Internet and its value-added services, OTA (Over-the-Air) technology will be more and more frequently developed. In this paper, China Mobile OTA Server System Structure is studied, meanwhile, the embody implementation of OTA server management platform based on WuHan TianYu corporation is analysed. The main aspect of this article is: First,ayalysing the whole design thinking of OTA server. The system structure pictures and data stream pictures are put forward, the correlation of system function modules and interface design are ayalysed. moreover, the run management, error disposal, system safety, and maintenance of the server are studied and ayalysed. Second,illustrating the design and implementation of monitor system. Monitor system client and monitor system server make up of monitor system, adopting CMPP(China Mobile Peer to Peer) protocol for communications. It is capable of dynamic showing the run circumstances of system function modules. In fact, it is very important for system stability. After that, describing the design and implementation of communications module interface libraries. It is a DLL(dynamic link libraries), adopting short message asynchronism transmission for connecting gateway. In fact, it improves system transplant and efficiency of sending short message to a great extent. Finally,Discussing the data synchronization questions of OTA server. Some security questions, such as short message synchronization, preventing short message drop, sending short message again are studied.
