摘要

在未来移动通信中，低轨卫星网络为全球通信的实现发挥着重要作用。针对大规模低轨卫星网络中大量用户频繁进行并发切换导致切换成功率下降及信令开销过大的问题，提出了一种基于用户群组的低轨卫星网络多星切换策略。地面用户在触发切换时，将满足自身通信需求的候选切换卫星信息发送给接入卫星，接入卫星在考虑用户切换成功率、卫星吞吐率和卫星负载均衡的条件下将用户分组，完成整个切换过程。设计了一种基于用户群组切换的信令交互流程，并分析了系统切换的信令开销。仿真结果表明，基于用户群组的低轨卫星网络多星切换策略可以有效地减少网络重复信令的传输，降低系统信令开销，同时该切换策略可以有效地提高用户切换成功率和卫星吞吐率，以平衡卫星网络负载。

Abstract

LEO satellite network plays an important role in global communication in the future mobile communication.In large-scale LEO satellite networks

frequent concurrent handoffs by a large number of users will reduce the handover success rate and increase the signaling overhead.In order to solve this problem

a multi satellite handover strategy based on user group for LEO satellite networks was proposed.When triggering the handover

the user will send the candidate handover satellites that meet its own communication needs to the access satellite.The access satellite groups users considered the conditions of user handover success rate

satellite throughput rate and satellite load balancing to complete the whole handover process.A signaling interaction process of handover strategy based on user group was designed

and the signaling overhead of group handover was analyzed.The simulation results show that the multi-satellite handover strategy of LEO satellite network based on user group can effectively reduce the transmission of network repeated signaling and reduce the system signaling overhead.At the same time

it can effectively improve the user handover success rate and satellite throughput

and balance the satellite network load.
