空天地一体化应急通信研究

Research on Space-Air-Ground Integrated Emergency Communication Networks

为了解决因自然灾害等因素造成无线网络损毁的问题,需采用各种应急通信技术快速恢复无线通信网络覆盖。首先分析了无线网络中较易受自然灾害破坏的节点,然后对能够快速恢复无线基站的多种应急通信平台进行对比分析,对恢复基站回传可采用的多种方案和基站供电方案进行了探讨。通过分析,发现各种应急通信平台都有其适用的应急通信场景,各种应急通信方案应相互协同工作,形成空天地一体化应急通信方案。最后对应急通信需要进一步研究的方向进行了展望。

In order to solve the problem of wireless network damage caused by natural disasters and other factors,various emergency communication technologies are needed to quickly restore the coverage of wireless communication network.This paper first analyzes the nodes that are vulnerable to natural disasters in wireless networks,then provides a comparative analysis on various emergency communication platforms for quickly restoring base stations,and discusses various solutions for recovering the backhaul of base stations and the power supply solutions for base stations.Through analysis,it is found that all emergency communication platforms have their own applicable scenarios,and various emergency communication solutions should work in a coordinated manner and form a space-air-ground integrated emergency communication solution.Finally,the future research directions of emergency communications are prospected.
