天地一体化接入网切片资源管理技术综述

Review of Slice Resource Management Technology in Space-Integrated-Ground Access Network

随着全球广域覆盖的天地一体化信息网络中,差异化业务的爆炸式增长,迫切需要在天地一体化接入网切片中,对无线与计算资源进行按需、动态管理,实现精细化的业务响应与服务保障。针对天地一体化接入网切片资源管理技术进行综述,总结天地一体化接入网切片资源管理的研究现状,分析未来天地一体化接入网切片系统的无线频谱资源高隔离、多维跨域计算资源协同管理、复杂异构网络实时决策需求,进而对相应的关键技术进行展望。

With the explosive growth of differentiated services,it is urgent to manage wireless spectrum and computing resources on demand dynamically in the sliced access network(RAN)of the space-integrated-ground network.Resulting from that,refined and guaranteed qualities of services are achieved.Thus,it is necessary to study the dynamic management of spectrum and computing resources in the sliced RAN of space-air-ground integrated networks.The resource management technologies in sliced RAN of the space-integrated-ground were discussed.The current research status of resource management in the space-integrated-ground access network was summarized.The future demands of resource management in sliced RAN of the space-integrated-ground system were analyzed,included the high isolation of wireless spectrum resource,the collaboration of computing resources among space and ground parts,and the real-time heterogeneous resource management in complex sliced RAN of space-air-ground integrated networks.The corresponding key technologies of the three demands were provided.
