摘要：

面向全域一致通信体验的需求,协同天基、空基、地基网络,能够消除通信盲区、加强广域互联的空天地一体化融合组网是未来通信重要的发展方向之一。然而,现阶段的空天地一体化融合组网只在一些特殊场景中取得了初步的应用,距离消除通信盲区、广域万物智联的愿景仍然存在诸多挑战。首先,文中概述了未来的空天地一体化融合组网架构;然后,分别从硬件、协议、节点部署和服务保障的角度分析了融合组网过程中面临的四大挑战,包括基于专用硬件的网元节点带来的融合组网功能升级困难、现有卫星通信协议标准性能低、三维广域空间带来的活动基站选址困难以及多样化业务难以进行差异化保障等问题。针对上述挑战,分别介绍了面向卫星的轻量级虚拟化技术、基于5G技术的卫星通信系统、水平与垂直面解耦的的活动基站选址和端到端的空天地一体化网络切片4个解决方案,为空天地一体化融合组网的发展提供参考。

Abstract:

The air-space-ground integrated network has been regarded as one of the enable technologies in the future to provide consistent communication experience all over the world.Based on the integration of the air,space and ground network,the area with no communication coverage can be eliminated and interconnection between remote areas can be strengthened.However,the current air-space-ground integrated network has only achieved the preliminary application in some special scenarios,and there are still many challenges to achieve the goal of eliminating the blind area and strengthening the connection.This paper first outlines the structure of the future air-space-ground integrated network.Then,four major challenges encountered in the network integration process are analyzed from the perspectives of hardware,protocols,node deployment and service assurance,including the difficulty of network function evolution raised by dedicated hardware,the low performance of current satellite communication protocol,the deployment of the flying base station in a broad 3D area and the differentiate quality guarantee of various services.Finally,four typical solutions to overcoming the above challenges are summarized to provide reference for the future air-space-ground integrated network,including light-weighted network function virtualization in the satellite,5G based satellite communication system,deployment of the flying base station based on horizontal and vertical decoupling and end-to-end integrated network slicing.

Key words: integrated network, light-weighted virtualization, evolution of space communication protocol, deployment of flying base station, integrated network slicing
