摘　　要：卫星互联网作为未来关键的通信基础设施之一,面对日益增长的通信需求和多样化的业务场景,资源调度策略的优化显得尤为关键。然而,当前卫星网络建设体制尚未充分考虑业务特性,缺乏基于业务优先级和特定条件下资源分配的智能化机制,难以在资源调度中充分感知和响应不同业务的需求。因此,针对卫星互联网中考虑业务特性下的资源调度的关键问题,展开调研和综述。首先,调研了卫星网络资源评估方法。然后,针对卫星网络资源调度策略,总结了三类调度策略。最后,总结了天地一体化网络在不同场景下的资源调度策略。As one of the key communication infrastructures of the future,the satellite Internet faces growing demands for communication and increasingly diverse service scenarios,making the optimization of resource scheduling strategies crucial.However,current satellite network architectures have yet to fully account for service-specific characteristics,lacking intelligent mechanisms for resource allocation based on service priority and specific conditions.This shortcoming limits the network's ability to effectively perceive and respond to varying service demands during resource scheduling.This paper presents a comprehensive review of resource scheduling strategies in the satellite Internet,focusing on the challenges related to service-driven resource allocation.First,methods for assessing satellite network resources are surveyed.Next,three categories of resource scheduling strategies in satellite networks are summarized.Finally,resource scheduling strategies for air-ground integrated networks across different scenarios are reviewed.
