基于低轨卫星互联网的双模通信终端技术

Dual-Mode Communication Terminal Technologies Based on LEO Satellite Internet

提出一种融合创新的解决方案——双模通信终端,集成了低轨道卫星通信和地面无线自组网的优点,提供弹性通信解决方案。终端能够实时获取集群路由,自主切换卫星通道和地面自组网通道,降低对卫星互联网天地传输信道的压力,实现多样化通信需求。在自组网内,终端利用地面无线自组网进行信息传输,建立用户集群并维护路由。超出自组网边界时,终端自动切换到卫星通信模式并维系网络。该技术有望满足各种场景的通信需求,包括应急响应和现场快速部署等。

This article proposed a fusion and innovative solution-a dual-mode communication terminal,which integrated the ad-vantages of low-orbit satellite communications and terrestrial wireless self-organizing networks to provide flexible communication solu-tions.The terminal could obtain cluster routing in real time and autonomously switch between satellite channels and ground ad hoc net-work channels,reduced the pressure on satellite Internet space and ground transmission channels and realized diversified communica-tion needs.Within the self-organizing network,the terminal used the terrestrial wireless self-organizing network to transmit information,established user clusters and maintain routes.When exceeded the boundary of the self-organizing network,the terminal automatically switched to satellite communication mode and maintained the network.This technology is expected to meet the communication needs of various scenarios,including emergency response and rapid on-site deployment.
