摘　　要：为了解决因自然条件不允许或者建网不经济区域的无线信号覆盖,或保障因自然灾害等导致的地面网络中断等应急、救灾场景的通信,以及大众终端直连卫星的问题,业界开始重视NTN网络的研究工作。以卫星直连为代表的NTN网络兼顾了5G网络的特点,其最大的贡献在于解决了大众终端直连卫星的问题,而不需要专门的终端。重点研究了NTN网络的应用场景、关键技术等,同时对NTN网络的发展进行展望。In order to solve the problem of wireless signal coverage in areas with poor natural conditions or sparse population,or to ensure communication in emergency and disaster relief scenarios where the ground network is interrupted caused by natural disasters,and to solve direct connection between public terminals and satellites,NTN networks are paid attention from the industry.NTN networks,represented by satellite direct connection,take into account the characteristics of 5G network,and the biggest contribution is to solve the problem of mass terminal direct connection to the satellite,without the need for special terminals.It focuses on the application scenarios and key technologies of NTN networks,and also discusses the development of NTN networks.
