摘要：

针对高低轨混合卫星网络中异构链路性能差异导致资源分配效率低的问题，提出一种高低轨混合卫星网络动态资源联合优化分配算法。首先，综合考虑卫星剩余服务时间、可用带宽资源和链路时延等性能指标，设计了一种面向业务需求基于多属性加权的卫星链路性能评估方法，实现区分业务的接入卫星选择；在此基础上，以网络频谱效率优化为目标，引入带宽资源块概念，通过设置卫星接入负载门限，设计了一种基于接入选择结果的卫星网络动态资源联合优化分配策略，并对算法性能进行了仿真分析。结果表明，所提算法能够实现面向业务类型的动态资源分配，在有效提高各类业务请求接受率的基础上，网络频谱效率得到明显提升。

Abstract:

To address the low resource allocation efficiency caused by the performance differences of heterogeneous links in low Earth orbit-geostationary Earth orbit hybrid satellite networks, a dynamic joint resource allocation optimization algorithm for low Earth orbit-geostationary Earth orbit hybrid satellite networks is proposed. This algorithm first comprehensively considers performance indicators such as satellite remaining service time, available bandwidth resources, and link latency, designing a multi-attribute weighted satellite link performance evaluation method tailored to service demands, enabling differentiated satellite selection for business access. Building on this foundation, with the goal of optimizing network spectral efficiency, the concept of bandwidth resource blocks is introduced. By setting satellite access load thresholds, a dynamic joint resource allocation optimization strategy based on access selection results is designed. Simulation analysis of the algorithm’s performance demonstrates that the proposed approach enables dynamic resource allocation based on service types, significantly improving the acceptance rate of various service requests while enhancing network spectral efficiency.

Key words: low Earth orbit-geostationary Earth orbit hybrid satellite network, access selection, resource allocation, joint optimization
