在卫星网络拿航空节点的特征进主要考虑,例如高移动速度,长通讯距离,和高连接频率,这篇文章为 IP/low 地球轨道(狮子座) 建议一个面向航空的活动性管理方法卫星网络。由介绍地面车站的概念,即时范围区域,建议方法使用 ground-station-based IP 寻址方法和房间寻呼象寻呼费用一样策划 IP 有约束力的更改请求的频率到减少。与寻呼比较活动 IP (P-MIP ) 方法和移交无关的 IP 活动性管理方法被数学分析和模拟验证建议方法能减少管理费用。因为它从增加的节点速度和最新来的连接率受到更少影响,支持航空节点也拥有更好的能力。
Taking into chief consideration the features of aviation nodes in satellite networks, such as high moving speed, long communication distance, and high connection frequency, this article proposes an aviation-oriented mobility management method for IP/low earth orbit (LEO) satellite networks. By introducing the concept of ground station real-time coverage area, the proposed method uses ground-station-based IP addressing method and cell paging scheme to decrease the frequency of IP binding update requests as well as the paging cost. In comparison with the paging mobile IP (P-MIP) method and the handover-independent IP mobility management method, as is verified by the mathematical analysis and simulation, the proposed method could decrease the management cost. It also possesses better ability to support the aviation nodes because it is subjected to fewer influences from increased node speeds and newly coming connection rates.
