卫星移动通信系统体系结构及建模

System Structure and Modeling of Satellite Mobile Communication System

卫星移动通信是实现全球无缝覆盖通信的必要手段。由于卫星移动信道的特殊性,使得卫星移动通信系统有别于地面网通信系统。目前国内在建设自己的卫星移动通信系统方面尚属空白。针对卫星移动通信的特点,提出一种卫星移动通信体系结构,从传输模型、通信体制和信令结构几方面对体系进行了设计,并在此基础上提出了适用于我国实际情况下卫星移动通信的呼叫模型,为未来国内建设自己的卫星移动通信系统提供了参考依据。该呼叫模型对未来卫星移动通信系统的应用具有一定的借鉴意义。

Satellite mobile communication is an indispensable means for global communication without any gap. At present, the field of satellite mobile communication system is still blank in China. As the result of particularity of satellite mobile channel, the satellite mobile communication system is discriminated with the system on the earth. Corresponding with the characteristic of satellite mobile communication, a systematic structure of satellite mobile communication system is proposed. The transmission model, communication mechanism and message structure are elaborated, which will provide some reference for the building of satellite mobile communication system in China in the future. To adapt to the situation of China, a paging model based on this system is also proposed at the end, which is helpful for the coming application of the satellite mobile communication system.
