摘　　要：近年来随着卫星互联网技术的不断进步,卫星通信运营行业的主体业务正在从传统的转发器租赁和视频传输向着宽带接入等数据传输演进,进而带来了卫星运营商网络建设模式和网络运维架构等的变革。为了满足不同行业场景、不同类型业务应用对网络的差异化需求,运营商往往需要部署多套异构基带系统。而当前不同基带系统间网管无法互通、频带资源仅能在各系统内部进行一定程度动态调度的现状,使得卫星资源的规划和调配缺乏灵活性,容易引起资源碎片化。对上述背景下带来的不同基带系统间的载波调控运维需求与挑战开展分析,并对多基带系统载波统一调控方案进行研究,力图实现频谱资源合理配置、灵活调配,从而充分释放无线网络资源价值。With the continuous progress of satellite internet technology,the main business of the satellite communication operation in‐dustry is evolving from traditional transponder leasing and video transmission to data transmission such as broadband access,which has brought about changes in the network construction mode and network operation and maintenance architecture of satellite operators.In order to meet the differentiated needs of different types of business applications on the network,operators often need to deploy multiple heterogeneous baseband systems.However,due to the incompatibility of different baseband systems,the frequency resources can only be scheduled in a certain system.Which result in a lack of flexibility in satellite resource planning and allocation.This article analyzed the carrier regulation and maintenance needs and challenges brought about by the above background,and studied the unified carrier regulation scheme for multi baseband systems,aimed to achieve reasonable and flexible allocation of spectrum resources,thereby fully unleashing the value of wireless network resources.
