Abstract: This application discloses a network access method, a network device, and a terminal. The method includes: obtaining, by a network device, indication information, where the indication information is used to indicate whether the terminal supports air communication; and when the indication information indicates that the terminal supports the air communication, determining, by the network device, that the terminal is allowed to access a network in which the network device is located. In this application, a quantity of unmanned aerial vehicle terminals that access the network can be limited, reducing interference caused by the unmanned aerial vehicle terminals to another terminal in the same network as the unmanned aerial vehicle terminals, and improving communication quality of the another terminal.
