The process only needs a short time, and can not affect the flight of the unmanned aerial vehicle, and the switching process can possibly occur when the ground station system communicates with the unmanned aerial vehicle through the radio communication link, but because the switching process only needs a short time, even if the problem of overtime of the switching process is encountered, the switching process can be timely carried out to the mobile network communication link, and the control, the data transmission and the image transmission of the unmanned aerial vehicle can not be excessively affected, so that the communication quality of the radio communication link can be maintained. The handoff process may also occur when the ground station system communicates with the drone via the mobile network communication link, and the communication quality of the handed off radio communication link may be required to cause the ground station system to handoff to the radio communication link for communication with the drone.
