Abstract

A method of communicating data between a vehicle and a ground system is described. The method includes initiating a connection between a plurality of clients on a vehicle and a ground system, and communicating, in parallel, data between the plurality of clients and the ground system.

Claims

1. A method of communicating data between a vehicle and a ground system, the ground system comprising a plurality of access points, said method comprising:

initiating connections between a plurality of clients on a vehicle and at least two of the plurality of access points, wherein each client of the plurality of clients is configured to connect directly with an access point;

communicating, in parallel, data between the plurality of clients and the ground system via the at least two access points, wherein each client is in communication with a separate access point to facilitate providing faster data transfer between the vehicle and the ground system;

optimizing communications between the plurality of clients and the plurality of access points via a communication priority matrix created based at least in part on the number of clients and the number of available access points; and

ending communication between the plurality of clients and the at least two access points, and any association between the plurality of clients and the at least two access points, upon completion of a data communication.

2. A method in accordance with claim 1 wherein initiating connections between a plurality of clients and the at least two access points comprises configuring the plurality of clients to search for and connect with the at least two access points via a wireless network.

3. A method in accordance with claim 1 that further comprises providing the plurality of clients with data collected from a plurality of monitors onboard the vehicle.

4. A method in accordance with claim 1 wherein communicating, in parallel, data between the plurality of clients and the ground system via the at least two access points further comprises configuring each access point to provide parallel communications for a plurality of the clients.

5. A method in accordance with claim 1 wherein the communication priority matrix is created based on

a signal strength of each available access point.

19. A method in accordance with claim 1, wherein the vehicle is an airplane, the method further comprising performing said initiating connections based on determining that the airplane is on the ground.

6. A system for communicating data from a vehicle to a ground system, the ground system comprising a plurality of access points, said communicating system comprising a plurality of clients onboard the vehicle, each said client configured to communicate, in parallel with said other clients, with said ground system via the plurality of access points, wherein each said client is configured to connect directly with an access point and all of the data from each said client is communicated via only the access point with which the client is connected to facilitate faster data transfer between the vehicle and the ground system, said system further configured to end communications and associations between said clients and said access points upon completion of a data communication, said system further comprising a system manager configured to optimize communications between the plurality of clients and the plurality of access points via a communication priority matrix created based at least in part on the number of clients and the number of available access points.

7. A system in accordance with claim 6 wherein at least one of said clients is coupled to an engine monitor for transmitting data collected by the engine monitor to said ground system.

8. A system in accordance with claim 6 wherein at least one of said plurality of clients is coupled to an in-flight entertainment system for transmitting content updates from said ground system.

9. A system in accordance with claim 6 wherein at least one of said plurality of clients is coupled to an airplane avionics system for transmitting data collected by an Airplane Health Management system.

10. A system in accordance with claim 6 wherein each of said plurality of clients is configured to communicate with the plurality of access points via a wireless network.

11. A system in accordance with claim 10 wherein said wireless network comprises a terminal wireless LAN.

12. A system in accordance with claim 6 wherein said ground system comprises at least one of a ground system server and a maintenance server.

13. A system in accordance with claim 6 wherein said system manager is configured to monitor a detected signal strength from each of said access points.

14. A system in accordance with claim 6 wherein at least one of said plurality of clients onboard the vehicle is coupled to said system manager, and wherein said system manager is programmed to determine when the vehicle is within a predetermined range of a ground system.

15. A system in accordance with claim 6 wherein said system manager is further configured to:

determine whether an access point signal strength is sufficient for communication; and

determine which channels of said ground system access points are available for use.

16. A system in accordance with claim 6 wherein said system manager is further configured to utilize the communication priority matrix to assign a communication channel to each said respective client for use in communicating with said ground system.

17. A system in accordance with claim 6 wherein the vehicle includes a plurality of engines, a respective engine monitor coupled to each respective engine, and a separate one of said clients coupled to a respective one of said engine monitors.

18. A system in accordance with claim 6 wherein each of the access points is operable to communicate, in parallel, with a plurality of the clients.
