摘要
为满足下一代移动通信空、天、地一体全球无缝覆盖,随时随地安全可靠人、机、物无限连接的需求,星地一体融合组网技术成为第6代移动通信技术(6th-Generation Mobile Communication Technology,6G)潜在关键技术之一。其中,如何实现手机直接通过卫星进行通信成为产、学、研界关注的焦点。探讨了手机直连卫星面临的挑战及不同模式,介绍了相关商业项目进展,总结了目前需关注的问题,并为我国手机直连卫星产业的发展提出了相关启示建议。
In order to meet the requirement for seamless global coverage of next-generation mobile communication technology,such as the integration of space and ground,as well as unlimited connection of safe and reliable“human-machine-object”at anytime in anywhere,the integration of satellite and ground network becomes one of the potential key technologies of 6G(6th-Generation Mobile Communication Technology).Among them,how to achieve direct-to-device satellite communication becomes a focus of attention among the industry,academia and research community.Challenges and different modes faced by“direct-to-device satellite communication”are explored,the progress of related commercial projects is introduced,the current issues that need to be paid attention to are summarized,and relevant inspiration and suggestions for the development of China’s“direct-to-device satellite communication”industry are proposed.
