5G Emergency Cell Network Solution Based on Satellite Assistance.

5G is a next-generation broadband mobile communication technology with high speed, low latency and expansive connectivity that has been widely adopted and used in China. In recent years, natural disasters and other catastrophes have become increasingly common, and since emergency communications are key to responding to disasters and emergencies, it is critical to examine how 5G can be used more effectively for emergency communications. To meet the demand for emergency communication in the 5G era where multiple new technologies are naturally combined, the paper proposes the use of new technologies such as high-throughput satellites, 5G, and edge computing to improve the emergency disaster relief system. The system combines the advantages of the above three new technologies, integrates more terminal devices into the access, and can transmit audio and video from the scene, rapidly back to the rear command center through satellite links, realizing the goal of becoming air-ground integrated and service interoperable, effectively solving the needs of front and rear communications. The article finally verifies the correctness and effectiveness of the scheme through experiments.
