摘要

星地融合网络可以提供天空地海立体全场景信息覆盖，满足未来网络全业务差异化通信需求，已经成为6G发展的热点。首先，调研了低轨卫星星座和星地融合组网发展现状，讨论了星地融合组网面临的问题与挑战。针对星地融合网络结构复杂、拓扑高动态、设备及协议异质性强等特点，提出了基于分布式SDN控制器的软件定义星地融合智能无线网络体系架构，以进行高效地星地协同网络管控。最后，介绍了星地柔性可重构协同组网的关键技术，并对未来发展进行了展望。

Abstract

With the superiorities of providing network services for all scenarios of three-dimensional space

air

ground

and ocean

and satisfying the future network differential requirements on all services

the satellite-terrestrial integrated network (STIN) has become a hot spot in the development of 6G.Firstly

the current research development of the low-orbit satellite constellation and STIN were reviewed

and the challenges faced by the integrated satellite-terrestrial networking were discussed.Then

the software defined intelligent system architecture of the integrated satellite-terrestrial wireless network based on distributed SDN controllers was proposed to address the characteristics of STIN such as the complex architecture

high dynamic of network topology

the heterogeneity of network devices and protocols

which facilitated efficient satellite-terrestrial collaborative network management and control.In the end

the key techniques of the satellite-terrestrial flexible and reconfigurable collaborative networking were outlined

and the future development were presented.
