Currently, various natural and man-made disasters are frequent, and the public safety situation is severe. Every year, tens of thousands of Unnatural death are caused, economic losses are difficult to measure, and emergency tasks are increasing. Sudden events such as terrorist attacks, mass incidents, crisis events, and natural disasters such as typhoons, floods, snowstorms, earthquakes, landslides, mudslides, etc. mostly occur without any warning, characterized by rapid expansion, wide coverage, and strong destructive power. Due to the harsh and ever-changing network environment, uncertain communication frequency, weak supply capacity, and complex and diverse scenarios, high demands are placed on the rapid response and resource coordination capabilities of rescue and rescue personnel. At present, long-distance private network communication mainly relies on wired or public networks, and equipment deployment and establishment require prior understanding of terrain and terrain, which takes a long time and incurs high network construction costs, making it difficult to meet the communication needs of rapid rescue.
