Tech Brief: Space-Terrestrial Integrated Architecture of Satellite + 5G + Broadcasting Convergence

To solve the problems of ground communication blind zones, delayed emergency broadcast response and high deployment costs in remote areas, the industry has built an integrated communication architecture of satellite + 5G + broadcasting. It breaks the networking barriers between GEO/NGSO satellite constellations, terrestrial 5G networks and broadcasting systems, realizing full-domain integration of resource complementation, protocol interconnection and service collaboration. The system adopts terrestrial 5G for urban high-density broadband coverage, broadcasting networks for public signal dissemination, and satellite communication to cover blind areas suchs as oceans, mountains and deserts.

This integrated architecture supports diverse services including emergency early warning broadcasting, rural broadband access, field private network communication and global IoT data collection, featuring wide coverage, high reliability, low latency and strong disaster resistance. It is fully compatible with C/Ka-band VSAT and FSS satellite terminals and RF equipment without large-scale hardware upgrades. As a core application paradigm for 6G space-terrestrial integration, the solution optimizes the overall space-ground communication layout and greatly improves public communication guarantee and industrial private network service capabilities.
