Description

technical field [0001] The present invention relates to the field of network and mobile communication technologies, in particular to a satellite mobile communication method integrated with a 5G network. Background technique [0002] Satellite mobile communication refers to referring to the transmission technical standards of terrestrial mobile communication, fully integrating with land cellular mobile communication, providing "backhaul" data transmission or direct user access, so as to achieve global coverage of mobile communication. Nowadays, the advantages of satellite mobile communication have attracted widespread attention in the industry. Since ground mobile communication systems cannot be deployed in remote areas, and satellite communication itself has a large coverage area, 5G key technologies are applied to satellite communication to realize satellite mobile integrated with 5G. Communication can provide high-speed communication services for remote areas. [0003] At...
