Abstract

A device to enable automatic wireless communication with an aircraft after the aircraft has parked at a gate. A terminal cellular bridge (TCB) enables the retrieval of data from, and the sending of data to the aircraft by an internet service provider. The internet service provider uses the Internet to send data to and receive data from a remotely located network operation center and data warehousing center. The data warehousing center provides secure data storage and retrieval, and data processing. The network operations center provides for system control and monitoring.

Claims

1. In an aircraft data communication system having an aircraft data acquisition system for gathering data about passenger usage of in-flight entertainment features, an aircraft data transmission system comprising:

a terminal cellular bridge on board each aircraft in communication with the aircraft data acquisition system and receiving control signals from the aircraft;

an internet service provider communicating with the terminal cellular bridge and routing data to and from the internet;

a data warehousing center communicating with the internet service provider over the internet; and

a network operations center communicating with the data warehousing center over the internet.

2. The aircraft data communication system of claim 1, wherein the terminal cellular bridge comprises a cellular phone module for global system mobile communication.

3. The aircraft data communication system of claim 1, wherein the terminal cellular bridge includes a global positioning system.

4. The aircraft data communication system of claim 1, wherein the terminal cellular bridge receives a control signal from the aircraft indicating that the aircraft is parked at the gate causing the terminal cellular bridge to initiate a call to the nearest internet service provider in preparation for data exchange with the data warehousing center.

5. The aircraft data communication system of claim 4, wherein the control signal is triggered by the opening of an aircraft door.

6. The aircraft data transmission system of claim 4, wherein the control signal is triggered by the parking brake being applied.

7. In an aircraft data transmission system having an in-flight entertainment data acquisition system, a terminal cellular bridge on each aircraft comprising:

an aircraft interface module for receiving data from the acquisition system and control signals from the aircraft;

a processor communicating with the aircraft interface module;

a cellular phone module communicating with the processor for transmitting data to or from the processor over a cellular phone network; and

a power supply module for providing power to the modules of the terminal cellular bridge.

8. The terminal cellular bridge of claim 7, further comprising a global positioning system module communicating with the processor to provide the processor aircraft location information.

9. The terminal cellular bridge of claim 7, wherein the aircraft interface module receives a control signal indicating the aircraft is parked at the gate.

10. The terminal cellular bridge of claim 9, wherein the control signal is triggered by the opening of an aircraft door.

11. The terminal cellular bridge of claim 9, wherein the control signal is triggered by the parking brake being applied.

12. The terminal cellular bridge of claim 7, wherein the processor begins to gather data from and/or send data to the in-flight entertainment systems upon power being applied.

13. The terminal cellular bridge of claim 7, wherein the aircraft interface module receives data about passenger usage of in-flight entertainment features.

14. The terminal cellular bridge of claim 7, wherein the in-flight entertainment features data comprises passenger use of telephone, audio/video, and game playing systems.

15. The terminal cellular bridge of claim 13, wherein the in-flight entertainment features data comprises passenger responses to surveys.

16. The terminal cellular bridge of claim 13 wherein the in-flight entertainment features data comprises purchases by passengers along with billing information.

17. The terminal cellular bridge of claim 9 wherein the aircraft module receives a control signal that causes the cellular phone module in the terminal cellular bridge to become inactive.

18. The terminal cellular bridge of claim 17 wherein the control signal is triggered by an aircraft door closing.

19. The terminal cellular bridge of claim 17 wherein the control signal is triggered by an aircraft parking brake being released.
