摘　　要：低轨卫星通信技术能够为地面用户提供广覆盖、大容量、高可靠的服务,是未来网络的关键支撑技术之一。手机直连低轨卫星技术具有便携、低成本和用户规模大等优势,具有广阔的市场和应用前景,同时其对低轨卫星的服务资源也有了相应的需求。面向低轨卫星资源受限的场景,提出了一种综合考虑通信、感知、计算和存储的资源模型,并据此提出一种用户分配策略,仿真结果表明,该策略相比于其他3种方法,能够达到更高的资源利用率,服务更多手机用户,也为手机直连卫星技术的发展提供了理论支撑。Low earth orbit(LEO)satellite communication technology can provide ground users with broad coverage,high capacity,and high reliability services,making it one of the key supporting technologies for future networks.Direct-to-mobile satellite communication technology offers advantages such as portability,low cost,and large user scalability,promising extensive commercial and application prospects.Simultaneously,it generates corresponding demand for service resources from LEO satellite.In scenarios where LEO satellite resources were constrained,a service model was proposed that comprehensively considers communication,sensing,computation,and storage.Based on this model,a user allocation method was proposed.Simulation results indicate that this strategy,compared to three other methods,achieves higher resource utilization rates,serves more mobile phone users,and provides theoretical support for the development of direct-to-mobile satellite communication technology.
