Abstract

A system for providing temporary, transportable cellular communications networks is disclosed. The system includes at least one mobile base station and a control system. The mobile base station can include an aerial vehicular base station with a frame and propellers mounted on the frame that enable flight of the aerial vehicular base station while the control system is configured to control the flight path and functioning of the aerial vehicular base station. The aerial vehicular base station includes hardware and software components for providing cellular network coverage for short ranges. The control system determines the safe flight path for the aerial vehicular base station to reach a service location to provide cellular network coverage. The aerial vehicular base station identifies the closest base stations and available spectrum at the service location to provide communication services for the user equipment at the service location.

First claim

What is claimed is:

1. A system for providing transportable cellular communication networks comprising:
one or more aerial, vehicular base stations, wherein each of the one or more aerial, vehicular base stations includes communication hardware that facilitates cellular communications for one or more user devices; and
a control system including at least:
at least one storage device storing processor-readable instructions; and
one or more processors executing the processor-readable instructions that cause the one or more processors to control the one or more aerial, vehicular base stations in a void area for facilitating the cellular communications for the one or more user devices, wherein the void area is a geographical location with sub-optimal communications network coverage,

wherein to control the one or more aerial, vehicular base stations the one or more processors are to further:
identify the geographical location of the void area based at least on data regarding one or more terrestrial base stations operating at sub-optimal levels within the void area; and
determine a number of the one or more aerial, vehicular base stations required to service the void area based at least on a network traffic capacity of each of the one or more aerial, vehicular base stations, an expected network traffic, and an extent of the void area.

2. The system of claim 1 , wherein to control the one or more aerial, vehicular base stations the one or more processors are to further:
identify a safe flight path from a current geographical location of the one or more aerial, vehicular base stations to the geographical location of the void area,
wherein the safe flight path has a lower risk of damage to at least one of the one or more aerial, vehicular base stations as compared to other deployment paths between the current geographical location of the at least one aerial, vehicular base station and the geographical location of the void area.

3. The system of claim 2 , wherein to identify the safe flight path to the geographical location the one or more processors are to further:
receive prior incident data including frequency of occurrence of emergencies similar to a current emergency at the geographical location, wherein the prior incident data is received for each geographical location enroute from the current geographical location of the at least one aerial, vehicular base station to the geographical location of the void area; and
receive current values of environmental factors related to the current emergency at each of the enroute geographical locations.

4. The system of claim 3 , wherein to identify the safe flight path to the geographical location the one or more processors are to further:
obtain a weighted average of the current values of the environmental factors for the enroute geographical locations;
generate a probability map of the geographical location and the enroute geographical locations based on the weighted averages; and
identify the safe flight path through one or more of the enroute geographical locations having lower values for the weighted averages.

5. The system of claim 1 , wherein to control the one or more aerial, vehicular base stations the one or more processors are to further:
receive sensor data from at least one of the one or more aerial, vehicular base stations wherein the sensor data provides current values for environmental factors.

6. The system of claim 5 , wherein to control the one or more aerial, vehicular base stations the one or more processors are to further:
determine that a current location of the at least one aerial, vehicular base station has to be changed based on the sensor data;
recalculate a safe flight path to a new geographical location for the at least one aerial, vehicular base station, wherein the new geographical location has a lower risk of damage due to a current emergency to the at least one aerial, vehicular base station than the current location; and
provide the recalculated safe flight path to the at least one aerial, vehicular base station.

7. A method of providing cellular communication networks comprising:
providing one or more aerial, vehicular base stations, wherein each of the one or more aerial, vehicular base stations includes communication hardware that facilitates cellular communications for one or more user devices;
providing a control system for the one or more aerial vehicular base stations;
including within the control system, at least one storage device storing processor-readable instructions and one or more processors executing the processor-readable instructions that cause the one or more processors to control the one or more aerial, vehicular base stations in a void area, wherein the void area is a geographical location with sub-optimal communications network coverage;
controlling the one or more aerial, vehicular base stations by the one or more processors by:
identifying the geographical location of the void area based at least on data regarding one or more terrestrial base stations operating at sub-optimal levels within the void area; and
determining a number of the one or more aerial, vehicular base stations required to service the void area based at least on a network traffic capacity of each of the one or more aerial, vehicular base stations, an expected network traffic, and an extent of the void area.

8. The method of claim 7 , wherein controlling the one or more aerial, vehicular base stations further comprises: identifying, by the one or more processors, a safe flight path from a current geographical location of at least one of the one or more aerial, vehicular base stations to the geographical location of the void area,
wherein the safe flight path has a lower risk of damage to the at least one aerial, vehicular base station as compared to other deployment paths between the current geographical location of the at least one aerial, vehicular base station and the geographical location of the void area.

9. The method of claim 8 , wherein identifying the safe flight path to the geographical location further comprises:
identifying, by the one or more processors, the current geographical location of the at least one aerial, vehicular base station; and
receiving, by the one or more processors, prior incident data including frequency of occurrence of emergencies similar to a current emergency at the geographical location, wherein the prior incident data is received for each geographical location enroute from the current geographical location of the at least one aerial, vehicular base station to the geographical location of the void area.

10. The method of claim 9 , wherein identifying the safe flight path to the geographical location further comprises:
receiving, by the one or more processors, current values of environmental factors related to the current emergency at each of the enroute geographical locations.

11. The method of claim 10 , wherein identifying the safe flight path to the geographical location further comprises:
obtaining, by the one or more processors, a weighted average of the current values of the environmental factors for the enroute geographical locations;
generating, by the one or more processors, a probability map of the geographical location and the enroute geographical locations based on the weighted averages; and
identifying, by the one or more processors, the safe flight path through one or more of the enroute geographical locations having lower values for the weighted averages.

12. The method of claim 7 , wherein to controlling the one or more aerial, vehicular base stations further comprises:
receiving, by the one or more processors, sensor data
