多元星座天基移动通信网络模型研究

Mobile Communication Astro-network Based on Multi-constellation

随着用户对移动通信需求的大量增加 ,3G、基于WAP及WAPoverIP等领域的移动通信以及多媒体通信正在成为全球的研发热点 .如何构建完整的移动通信网络 ,以适应不断增加的用户及其对移动通信QoS的需求 ,是一个非常现实和急迫的问题 .从多元星座组网构架出发 ,探讨了天基移动通信网的组网模式 ;基于天基网环境对组网的方法、可能的模式进行了研判 .给出了多元星座的拓扑结构 ;提出了时域星座的动态路由策略 ;阐述了多元星族的主要特点 .

In this paper, a buildup model of mobile communication astro networks is discussed on the basis of the structure of multi constellation. How to set up the astro network(AN) and what are possible basic models of the network are estimated. The topology structures of multi constellation astro network(MCAN), dynamic router scheme of time zone constellation astro network and main characteristics of multi satellite family astro network in MCAN are presented. The issues of the relative focus of satellite mobile communication are also introduced.
