In the flood fighting and disaster relief in Henan, the thousand mile rescue of China Mobile's pterosaur "high altitude base station" of China Mobile PTEROSAUR was talked about. The screenshot of SMS once rushed to the microblog hot search, which attracted the attention and praise of many netizens. A netizen commented: "there is no need for airborne soldiers to risk their lives to open up the emergency communication lifeline like the 2008 Wenchuan earthquake. The people are supreme, long live the motherland! " The reporter learned from the Executive Committee of 2021 China International Digital Economy Expo that this cutting-edge technology will appear in the "innovation achievement press conference".

In late July, there was a rare continuous heavy rainfall weather process in Zhengzhou, Henan Province, which caused heavy rainstorms and torrential rains in the city and triggered floods. Among them, Mihe Town, Gongyi City triggered power failure due to flood, causing communication terminals. Mihe town became an information isolated island, and about 50000 people could not contact the outside world through communication. At that time, the "air emergency communication" from China Mobile played a role in restoring voice and data communication.

"On July 21 this year, The National Emergency Management Department urgently dispatched the Yilong large long endurance UAV emergency communication system, and at 18:21, the UAV entered the communication interruption area of Mihe town to perform the emergency communication support task." Li Zhuo of China Mobile Communication Group Hebei Co., Ltd. introduced that the Yilong UAV emergency communication system is equipped with China Mobile public network emergency communication base station, and successfully completed the tasks of mobile network coverage and directional sending of short messages in disaster areas. As of 23:20 on the same day, China Mobile's base stations had connected 3572 users, generated 2089.89m traffic, and the maximum number of users accessed in a single time was 648. 2704 valid numbers of people in disaster areas were sent out.

"China Mobile has built the first large fixed wing UAV mobile emergency space base station in China by using large fixed wing UAV to carry wireless communication base station and satellite transmission." Li Zhuo introduced that after three years of research and development, the base station was completed and put into use in 2021, reflecting the strength of China's independent innovation in communication technology. When the UAV rises to high altitude, it forms a temporary "base station tower", which can get rid of the constraints of ground power supply and communication return, and can provide emergency communication support with large area coverage at any time, place and all weather, which  can effectively solve the emergency communication problems in severe environments such as forest fires, earthquake disasters, flood disasters, serious damage to basic transportation facilities, isolated island areas, remote areas, and extreme weather.
