面向跨域协同的通感算一体化星地融合网络关键技术研究OA

To meet the requirements of global coverage in 6G,satellite networks are expected to provide continuous and reliable cross-regional services and to drive the evolution of network capabilities from connectivity-oriented operation toward cross-domain collaboration integrating sensing,communication,and computing.However,existing satellite-ground networks still exhibit limitations in supporting future multi-task and multi-scenario service provisioning.Focusing on cross-domain collaborative integrated sensing,communication,and computing satellite-ground networks,this paper first systematically reviews recent research progress from the perspectives of sensing-communication-computing integration,satellite-ground network support,and intelligent networking with cross-domain collaborative scheduling.A cross-domain collaborative functional architecture is then constructed,and the mapping between functional domains and network layering is summarized.On this basis,a deployable end-to-end network architecture is presented to support unified orchestration and joint scheduling of service chains.Furthermore,key technologies including integrated sensing-communication-computing waveform design,satellite-ground collaborative service orchestration with in-orbit intelligent computing,and service-oriented intelligent network support are discussed.Finally,future research directions are outlined from the aspects of heterogeneous collaboration and standardization,semantic-driven integration,and security and resilience enhancement,providing guidance for the design of efficient and intelligent integrated satellite–ground networks.
