摘要
为了实现全球化的无缝网络覆盖,陆、海、空、天四位一体化融合通信已成为未来6G通信的发展趋势。对陆海空天一体化通信的网络架构及对应的关键技术进行综合分析与设计,并进行一项平流层通信试验案例分析。首先,简要回顾陆海空天融合通信的的发展背景;其次,详细讨论陆海空天融合通信系统的三项关键技术:3D网络建模、频率规划以及移动性管理,特别地,强调一种基于Binomial-Delaunay四面体的新型网络模型;基于该模型,进一步讨论了频率规划方案和节点综合移动模型;然后,扼要讨论3D网络中的无人机信道建模、动态频谱资源共享、干扰管理和基于AI的网络设计等四项关键技术;最后,作为空间网络架构演进中的一环,提出一种分层、异构式融合通信网络架构,并展示一个近期完成的平流层通信试验。
To achieve global seamless network coverage,the integrated communications of land,sea,air,and sky is dominant in upcoming 6G communications.This article analyzes and designs the network architecture and corresponding key technologies of land,sea,air and space integrated communication,and conducts a case study of a stratospheric commu-nication experiment.First,we overview the evolution of land,sea,air,and space-integrated communications;second,three key technologies are investigated,including three-dimensional(3D)network modeling,frequency planning,and mobility management.In particular,this article stresses a new network model based on the Binomial-Delaunay tetrahedron;based on this model,a frequency planning scheme and a synthetic mobility model are further discussed.Then,the UAV channel modeling,dynamic spectrum resource sharing,interference management and AI(Artifi cial Intelligence)-based network design are sketched.Finally,as a milestone of the evolution of the spatial network architecture,a layered and heterogeneous network architecture is proposed and a recently completed stratospheric communication experiment is demonstrated.
