Abstract: A wireless network communication method, a network device, and a terminal, where the method includes: An uncrewed aerial vehicle traffic management entity receives an authorization request. The uncrewed aerial vehicle traffic management entity sends an authorization response. The authorization request is used to request authorization to control an uncrewed aerial vehicle by a terminal, and the authorization response is used to indicate whether the terminal is allowed to control the uncrewed aerial vehicle. Alternatively, the authorization request is used to request authorization to pair a terminal with an uncrewed aerial vehicle controller, and the authorization response is used to indicate whether the terminal is allowed to be paired with the uncrewed aerial vehicle controller.
