摘要
分析了将移动IP技术应用于星座卫星通信系统的优势及直接使用的缺陷,指出引入相关扩展技术的必要性。然后对蜂窝IP技术进行了简单介绍,指出了将该技术应运到无星际链路的星座通信系统中的可行性。根据蜂窝IP的特点,采用以信关站为中心结点的方式对卫星网络结构进行了改造,并对系统的切换、路由和位置管理进行了分析。最后对使用了蜂窝IP的卫星网络的性能进行了分析。
This paper first analyses the benefits and shortages of immediately using Mobile IP into a constellation satellite communication and then points out that using its spreading technology is necessary. Then the paper introduces some concepts of cellular IP,and gives us the feasibility of using it into a constellation satellite communication without inter - satellite link. According to the characters of cellular IP,the network of constellation satellite communication is changed,and its problems of handing off,routing and location management are analyzing. At last , the new network＇s performances are also analyzing.
