摘要 低轨卫星移动通信网络在实现全球移动通信方面具有很大优势。切换方案对于控制低轨卫星网络通信时延,提高卫星网络服务质量和链路带宽资源利用率具有重要意义。深入分析了星地链路切换和重计算路由问题,提出了一种低轨移动通信卫星链路切换算法。仿真实验表明,提出的卫星链路切换算法有较小的端到端时延、较好的稳定性和可定制性。 Low earth orbit（LEO） satellite network has a great advantage for global mobile communications. Handover scheme is very important to control end-to-end communication delay and improve quality of service and utilization of LEO satellite network link. Ground-satellite link handover and recomputing mutes problems were analysed in detail. Then,a link handover algorithm for LEO satellite mobile commtmication network was proposed. Simulation results show that the satellite link handover algorithm proposed has less end-to-end delay, and is stabler and more customizable.
