[0025] According to this embodiment of this application, an embodiment of a flight tag
obtaining method is provided. The flight tag obtaining method may be, but is not limited to being applied to an application environment shown in FIG. 1. A control terminal 104 obtains a takeoff geographic location of a first unmanned aerial vehicle (a unmanned aerial vehicle 102 as shown in FIG. 1) when the first unmanned aerial vehicle takes off, sends the takeoff geographic location to a server 106, and obtains a flight tag returned by the server 106, the flight tag being used for indicating whether the first unmanned aerial vehicle (the unmanned aerial vehicle 102 as shown in FIG. 1) is an unmanned aerial vehicle first taking off from the takeoff geographic location of the first unmanned aerial vehicle (the unmanned aerial vehicle 102 as shown in FIG. 1). Flight data (for example, the takeoff geographic location) of the unmanned aerial vehicle is sent to the server, to establish a common database of unmanned aerial vehicles on the server, to use the database to return the flight tag of the unmanned aerial vehicle to the control terminal, and further implement sharing of the foregoing flight tag of the unmanned aerial vehicle in social space.
[0026] Optionally, in this embodiment, the foregoing control terminal may include but is not

5 of multi-user interaction.
[0041] In addition, in manner 2) of this embodiment, the takeoff geographic location of the
first unmanned aerial vehicle may alternatively be sent to the server after the first unmanned aerial vehicle takes off, so that the server is synchronized with the obtained takeoff geographic location of the first unmanned aerial vehicle after a time interval. A synchronization process in which the 0 takeoff geographic location of the first unmanned aerial vehicle is sent to the server is separated, that is, a plurality of takeoff geographic locations obtained at particular time intervals is sent to the server together, to reduce a quantity of sending times, and therefore improve the efficiency of sending the takeoff geographic location to the server.
