摘　　要：2023年9月,随着华为发布全球首款支持双向卫星通信的商用手机,手机直连卫星成为了全球移动通信发展的焦点。手机直连卫星将推动地面移动通信系统的技术和产业进一步发展,满足全球无缝覆盖,用户随时随地随遇接入的业务需求,助力弥合社会的数字鸿沟。手机直连卫星属于移动卫星业务范畴,需要采用相应的卫星频率。卫星频率属于稀缺的太空资源,因此卫星频率是手机直连卫星发展要考虑的首要因素之一。文章从手机直连卫星的技术路线出发,首先阐述了国际手机直连卫星系统的主要三种技术路线,然后分析了手机直连卫星的可用频率,最后给出了相应的发展建议。文章对我国手机直连卫星的技术路线和使用频率进行了详细的分析,根据我国发展情况提出要按阶段进行发展,并建议加强对“星地同频”的卫星网络资料储备与技术研究,为后续推动我国手机直连卫星业务发展奠定基础。In September 2023,Huawei released the world’s first commercial mobile phone supporting two-way satellite communication.The satellite-direct-to-phone has become the focus of global mobile communication.The satellite-direct-to-phone will promote the development of technology and industry for the terrestrial mobile communication system to meet the global seamless coverage,users anytime,anywhere access to the business needs,and further bridge the social digital divide.The satellite-direct-to-phone belongs to the category of mobile satellite service,which needs to adopt the corresponding satellite frequency.The satellite frequency is a scarce space resource.Therefore,the satellite frequency is the one of primary factors to be considered in the development of the satellite-direct-to-phone.This paper starts from the technical route of the satellite-direct-to-phone,firstly expounds the main three technical routes of the international satellite-direct-to-phone system,then analyzes the available frequency of the satellite-direct-to-phone,and finally gives the corresponding development suggestions.This paper is the first time to analyze the technical route and available frequency of China’s satellite-direct-to-phone in detail.According to the development of China,it is proposed to develop satellite-direct-to-phone service in stages.It is suggested to strengthen the satellite network data reservation and technology research of"same frequency of satellite and terrestrial",to lay the foundation for promoting the development of China’s satellite-direct-to-phone service.
