Abstract

Disclosed embodiments may help an aerial vehicle network to provide substantially continuous service in a given geographic area. An example method may be carried out at an aerial vehicle that is at a location associated with the first geographic area in an aerial network that includes a plurality of geographic areas. The balloon may determine that it should update its vehicle-state in accordance with a vehicle-state profile for the first geographic area. Then, in response, the balloon may determine the vehicle-state profile for the first geographic area, which may include one or more state parameters for balloons operating in the first geographic area. The balloon may then operate according to the vehicle-state profile for the first geographic area.

subsequently determining, by a computing system of the aerial vehicle, that the aerial vehicle has moved to a location associated with a first geographic area in the aerial network, and that a vehicle-state of the aerial vehicle should be updated in accordance with a vehicle-state profile for the first geographic area; and

in response to determining that the vehicle-state profile should be updated;

determining the vehicle-state profile for the first geographic area, wherein the vehicle-state profile comprises one or more state parameters for aerial vehicles operating in the first geographic area; and

causing the aerial vehicle to switch from operation according to the vehicle state profile for the second geographic area to operate according to the vehicle-state profile for the first geographic area, wherein the vehicle state profile for the first geographic area comprises one or more state parameters for aerial vehicles operating in the first geographic areas, and wherein the vehicle state profile for the second geographic area comprises one or more state parameters for aerial vehicles operating in the second geographic area.

determining that the aerial vehicle has moved from a location that is outside of the first geographic area to a location within the first geographic area.

3. The method of claim 1, wherein determining that the aerial vehicle should be updated with vehicle-state information for the first geographic area comprises:

determining that the aerial vehicle has moved from a first location that is outside of a border area of the first geographic area to a location within the border area of the first geographic area.

4. The method of claim 1, wherein determining that the vehicle-state profile should be updated comprises:

determining a direction in which the aerial vehicle is travelling; and

determining that the direction in which the aerial vehicle is travelling is towards the first geographic area.

5. The method of claim 1, wherein determining the vehicle-state profile for the first geographic area comprises:

sending a profile-update request; and

receiving, as a response to the profile-update request, at least a portion of the vehicle-state profile for the first geographic area.

6. The method of claim 5, wherein sending the profile-update request comprises sending the profile-update request to one or more other aerial vehicles in the aerial network, and wherein at least a portion of the vehicle-state profile for the first geographic area is received from one or more of the other aerial vehicles.

7. The method of claim 5, wherein sending the profile-update request comprises:

sending the profile-update request to a ground-based station that is associated with the first geographic area, wherein at least a portion of the vehicle-state profile for the first geographic area is received from the ground-based station.

8. The method of claim 1, wherein determining the vehicle-state profile for the first geographic area comprises:

searching a communication channel for a vehicle-state signal; and

receiving the vehicle-state signal via the communication channel, wherein the vehicle-state signal indicates at least a portion of the vehicle-state profile for the first geographic area.

9. The method of claim 1, wherein the vehicle-state profile for the first geographic area indicates one or more operational parameters for aerial vehicles that are operating in the first geographic area.

10. The method of claim 9, wherein the one or more operational parameters comprise one or more of:

(a) at least one parameter indicating a communication protocol or protocols to be used in the geographic area, (b) at least one parameter providing routing information for the geographic area, (c) at least one parameter relating to transmission power for aerial vehicles operating in the geographic area, (d) at least one parameter indicative of error correction coding that should be implemented by an aerial vehicle in the geographic area, (e) at least one parameter indicative of a desired topology for the aerial network in the geographic area, (f) at least one parameter that provides information related to ground-based stations or other fixed systems in the geographic area, (g) at least one parameter indicative of power management that should be implemented by an aerial vehicle in the geographic area, (h) at least one parameter affecting the horizontal and/or altitudinal movement of the aerial vehicle, and/or (i) at least one parameter providing information for complying with a legal requirement for the geographic area.

11. The method of claim 1, wherein causing the aerial vehicle to operate according to the vehicle-state profile for the first geographic area comprises updating the vehicle-state for the aerial vehicle based on the vehicle-state profile for the first geographic area.

12. The method of claim 1, further comprising:

subsequently, after causing the aerial vehicle to operate according to the vehicle-state profile for the first geographic area, determining that the aerial vehicle is again at a location associated with a second geographic area of the aerial network;

determining that the vehicle-state of the aerial vehicle should be updated in accordance with the vehicle-state profile for the second geographic area; and

in response to determining that the vehicle-state should be updated;

causing the balloon to again operate according to the vehicle-state profile for the second geographic area.

13. A computer-implemented method comprising:
