摘要
面向6G的星地一体化网络通过卫星网络与地面网络的优势互补、紧密融合,将扩大网络覆盖范围,提升网络整体效率,从而实现全球立体无缝覆盖网络。概述了星地融合网络发展现状及趋势。分析了星地融合网络发展路径,从过去的业务融合到现在的体制融合再到未来的系统融合。指出了面向6G的星地融合一体化组网中网络架构、空口传输、组网方式以及频率管理方面存在的挑战以及未来可能的发展方向。
Satellite-terrestrial integrated networks towards 6G will expand the coverage and improve the overall efficiency of the network through the complementary advantages and deep integration of the satellite and the terrestrial networks,so as to realize the global three-dimensional seamless coverage network.Firstly,the development status and trend of satellite-terrestrial integrated networks are summarized.Then,the development path of satellite-terrestrial integrated networks is analyzed,that is,from the past business integration to the present system integration,and then to the future system integration.Finally,the challenges and the possible development direction in the future of network architecture,air interface transmission,networking mode and frequency management in satellite-terrestrial integrated networks towards 6G are pointed out.
