面向5G-Advanced和6G的星基移动通信网络标准技术研究OA

In response to the networking requirements of 5G-Advanced and 6G,mobile communication standards organizations have initiated studies on the architecture and protocols for satellite-based mobile communication networks,which indicate a trend toward supporting network function entities on satellites.This paper summarizes the standardization evolution paths of 3GPP and ITU,proposing interface protocols,mobility management,and store-and-forward technologies for satellite-based base station architectures in 5G-Advanced.Additionally,it introduces satellite information management functions and service procedures for satellite-based core networks in 6G.The proposed solutions provide architectural,protocol,and procedural references aligned with 3GPP standards for satellite-based access networks and core networks in future mobile communication systems,thereby accelerating the standardization and industrialization of satellite-based and integrated space-ground mobile communication networks.
