Background technique

Unmanned Aerial Vehicle (UAV), referred to as UAV, is a non-manned aerial vehicle operated by radio remote control equipment and self-contained program control device. UAVs are actually the collective name of unmanned aerial vehicles. They can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft and unmanned aircraft. Umbrella wing machine, etc.

With the rapid development of drone technology, cost reduction and functional improvement, drones are increasingly used in ordinary consumers. At present, no one is connected to aerial photography, agriculture, plant protection, micro-self-timer, express transportation, disaster relief, observation of wildlife, monitoring of infectious diseases, mapping, news reports, power inspection, disaster relief, film and television shooting, manufacturing romance, etc. The use of the drone itself has been greatly expanded, and various countries are actively expanding the application and development of drone technology.

In order to further expand the scope of application of drones, the 3rd Generation Partnership Project (3GPP) has adopted the project of Enhanced Support for Aerial Vehicles to research and standardize cellular networks. Man-machine provides services that meet the needs.
