综合移动信息系统的软件设计与实现

The Software Design and Realization of Integration Mobile Information System

综合移动信息系统具有有线网络系统所不具备覆盖范围广、广播能力强、移动性能好等特点，且适合我国国情。根据“北斗”卫星和世广卫星的特点，利用“北斗”卫星简短报文功能和世广卫星大容量数据播发能力，设计了具有非对称数据通信功能的综合移动信息系统；讨论了该系统的工作原理；详细论述了系统的软件设计与实现，为大容量信息播发和移动用户通信提供了有效手段。

The integration mobile information system has the characteristics of wide coverage, huge capacity broadcast and well mobility. It adapts to our country because of its advantage compared with the lined network system. The paper introduces the characteristics of ＂Beidou＂ satellite and WorldSpace satellite, and designs the integration mobile information system with non symmetry data communication, which makes use of the messaging of ＂Beidou＂ satellite and huge data-transmitting capacity of WorldSpace satellite. It also discusses the work principle of the system and the design of system software in detail. The system provides a valid measure for huge capacity broadcast and mobile user communication education.
