摘　　要：基于大型可展开天线的对地静止轨道(GEO)卫星移动通信系统是未来卫星移动通信发展的重要方向。通过对GEO卫星移动通信系统与地面蜂窝移动通信系统和低轨卫星移动通信系统的比较,分析研究了GEO卫星移动通信系统的系统特征,并总结了其对系统结构设计所产生的影响,包括传输时延、功率受限性、小区结构、相邻小区干扰、用户访问限制和移动终端速率等。在此基础上,提出了GEO卫星移动通信系统的体系结构特征和不同组网应用模式。为基于GEO的卫星移动通信系统的体系架构提供了参考。The multi-beam GEO （Geostationary Earth Orbit） mobile satellite system is the important development direction of satellite mobile communication system.By comparing the GEO mobile satellite system with ground cellular mobile communication system and the LEO mobile satellite system, the critical characteristics of the GEO mobile satellite system are discussed. Furthermore, the impact on system structure design are analyzed, including transmission delay, power limitation, cell structure, adjacent cell interference, access control and mobile terminal velocity. Based on the discussion and analysis, the architecture characteristics and different networking application modes of GEO mobile satellite system are proposed,which provides references to the architecture design of GEO mobile satellite communication system.
