Research review on spaceborne core network
摘要
Abstract
With the rapid evolution of 6G communication technology and space-air-ground integrated networks,the spaceborne core network,as a key supporting technology to achieve global seamless coverage and improve network service quality,has become a re-search focus jointly concerned by the academic and industrial communities.This paper systematically sorts out the research progress of the spaceborne core network.Firstly,it expounds the standard evolution path of 3GPP,ITU,and other standardization organizations in this field.Secondly,it analyzes its technical necessity from the perspectives of addressing the limitations of terrestrial communication and improving network performance,and demonstrates its implementation feasibility by combining satellite technology innovation and engi-neering practice verification.Subsequently,it deeply discusses key technologies including satellite-terrestrial distributed network archi-tecture,lightweight onboard core network,handover optimization,dynamic deployment,edge computing and caching.Finally,based on the existing research bottlenecks,it looks forward to the future research trends in directions such as intellectualization,anti-destruction enhancement,new service adaptation,and security and privacy protection,providing theoretical references for further research and ap-plication of the spaceborne core network.关键词
