Abstract: In a parcel delivery method and system, a server continuously receives recipient geographic position information (GPI) from a recipient terminal associated with and carried by a recipient, and unmanned aerial vehicle (UAV) GPI from a UAV loaded with a to-be-delivered parcel via a communication network, and transmits, to the UAV, destination information, which is the recipient GPI that is last received by the server. The UAV transports, based on the destination information from the server, the parcel to an unloading position where the recipient terminal is located.
