Abstract

The systems and methods are provided to provide communication coverage to an unmanned aerial vehicle. A proposed flight path of a UAV may be collected, and a communication signal distribution, such as a cellular signal distribution, along the proposed flight of the UAV may be determined. At positions having low or no communication signal, relays may be provided to improve a quality of the communication signal. The relay may be a ground device or an aerial vehicle. A stable and continuous communication between the UAV and user terminals during the entire flight path of UAV may be provided, and a coverage of cellular signal may be expanded.

First claim

What is claimed is:

1. A method of providing communication coverage to an unmanned aerial vehicle (UAV), said method comprising:
collecting a proposed flight path of the UAV;
determining a communication signal distribution along the proposed flight path of the UAV, the communication signal distribution being collected by another aerial vehicle flying along the proposed flight path; and
determining, based on the communication signal distribution, one or more locations along the proposed flight path of the UAV for arranging one or more relays, to provide communication coverage in one or more areas where a quality of communication signal is beneath a threshold value and/or where an available bandwidth for the UAV is beneath a threshold value.

2. The method of claim 1 , further comprising modifying the proposed flight path of the UAV.

3. The method of claim 1 , wherein determining the communication signal distribution further includes incorporating past experience data collected from other UAVs.

4. The method of claim 1 , wherein determining the communication signal distribution further includes incorporating past experience data collected from a communication service provider or receiving a preset setting of a communication service provider.

5. The method of claim 1 ,
wherein the one or more relays include one or more mobile relays,
the method further comprising:
arranging at least one of the one or more mobile relays within a certain distance from the UAV while the UAV is in flight.

6. An apparatus for providing communication coverage to an unmanned aerial vehicle (UAV), said apparatus comprising:
one or more processors configured to, individually or collectively:
collect a proposed flight path of the UAV;
determine a communication signal distribution along the proposed flight path of the UAV, the communication signal distribution being collected by another aerial vehicle flying along the proposed flight path; and
generate, based on the communication signal distribution, signals for arranging one or more relays at one or more locations along the proposed flight path to provide communication coverage in one or more areas where a quality of communication signal is beneath a threshold value and/or where an available bandwidth for the UAV is beneath a threshold value.

7. The apparatus of claim 6 , wherein each of the one or more relays comprises (1) a first communication unit capable of directly communicating with the UAV and (2) a second communication unit capable of communicating over a telecommunication network or a wired communication network.

8. The apparatus of claim 7 , wherein a plurality of the relays communicate with each other via the second communication units.

9. The apparatus of claim 6 , wherein a communication between the UAV and a telecommunication network switches to a communication between the UAV and the one or more relays when the UAV fails to receive a predetermined amount of communication resource from the telecommunication network.

10. The apparatus of claim 6 , wherein the communication signal distribution further includes past experience data collected from other UAVs.

11. The apparatus of claim 6 , wherein the communication signal distribution further includes past experience data collected from a communication service provider or a preset setting received from a communication service provider.

12. The apparatus of claim 6 , wherein the communication signal distribution includes a quality of telecommunication network signal along the proposed flight path of the UAV.

13. A system for providing communication coverage to an unmanned aerial vehicle (UAV), said system comprising:
an aerial vehicle different from the UAV and configured to collect a communication signal distribution along a proposed flight path of the UAV; and
a device configured to determine, based on the communication signal distribution, one or more locations along the proposed flight path of the UAV for arranging one or more relay devices, to provide communication coverage in one or more areas where a quality of communication signal is beneath a threshold value and/or where an available bandwidth for the UAV is beneath a threshold value.

14. The system of claim 13 , wherein the communication signal distribution further includes past experience data collected from other UAVs.

15. The system of claim 13 , wherein the communication signal distribution further includes past experience data collected from a communication service provider or a preset setting received from a communication service provider.

16. The system of claim 13 , wherein the communication signal distribution further includes a signal distribution determined based on real-time notice from a communication service provider.

17. The system of claim 13 , wherein the communication signal distribution includes a quality of telecommunication network signal along the proposed flight path of the UAV.
