为实现全球通信网络无缝覆盖，卫星通信将在未来发挥重要作用，国际上大量新兴商业公司相继开展卫星互联网系统规划和设计，发展态势不容小觑。在已有的地面移动通信协议体制基础上，通过适当改进，可利用移动手机终端与卫星建立直连通信。介绍了当前国内外手机直连卫星通信技术的发展现状及部分典型应用场景，详细分析了3GPP NTN标准演进情况，并初步阐述了未来存在的问题和挑战。
Abstract：In order to achieve seamless coverage of global communication networks, satellite communication will play an important role in the future.A large number of emerging international commercial companies have successively carried out satellite internet system planning and design, and the development trend cannot be underestimated.Based on existing ground mobile communication protocol system, through appropriate improvements, direct communication between mobile phone terminals and satellites can be established.This article introduces current development trend and some typical application scenarios of mobile direct satellite communication technology, analyzes in detail the evolution of 3GPP NTN standard, and preliminarily elaborates on future problems and challenges.
