Abstract

An example avionic data communication method includes establishing a plurality of available channels using a channel controller. The channel controller also establishes a quality of service for each of the plurality of available channels. The channel controller then selects one of the available channels. The quality of service of the selected channel is not less than the quality of service of another channel within the plurality of available channels. The method then communicates a type of data using the selected channel.

Claims

1. An avionic data communication method comprising:

establishing a plurality of available channels using a channel controller;

establishing a quality of service for each of the plurality of available channels using the channel controller;

selecting one of the plurality of available channels using the channel controller, the quality of service of the selected channel not less than the quality of service of another channel within the plurality of available channels;

selecting a type of data based on the plurality of available channels, the type of data having an associated cost-of-transmission that does not exceed a cost-of-transmission threshold for the selected channel; and

communicating the type of data using the selected channel,

wherein the communicating comprises communicating the type of data between an aircraft and a ground-based system,

wherein the cost-of-transmission threshold changes in response to changes in position of the aircraft relative to the ground-based system.

2. The avionic data communication method of claim 1, wherein the plurality of available channels includes a channel selected from a group that comprises a cellular channel, an Ethernet channel, a WiFi channel, and a WiMax or LTE channel.

3. The avionic data communication method of claim 1, wherein the channel controller is located within an aircraft.

4. The avionic data communication method of claim 1, wherein the type of data is selected from a group comprising a less critical data type and a more critical data type.

5. The avionic data communication method of claim 1, including prioritizing the communication of critical data above other types of data.

6. The avionic data communication method of claim 1, wherein the plurality of channels are at the same geographical location.

7. The avionic data communication method of claim 1, wherein the plurality of channels are different types of communication channels.

8. The avionic data communication method of claim 1, wherein the aircraft is stationary relative to the ground-based system during the communicating.

9. The avionic data communication method of claim 1, wherein the aircraft is docked relative to the ground-based system during the communicating.

10. An avionic data communication arrangement, comprising:

a channel controller configured to select a communication channel from a plurality of available communication channels, the selected communication channel having a quality of service that is not less than the quality of service of another communication channel within the plurality of available channels;

a data controller module configured to select data for transmission that has an associated cost-of-transmission that does not exceed a cost-of-transmission threshold for the established channel; and

a transmitter configured to communicate the selected data using the selected communication channel,

wherein the transmitter is configured to communicate the selected data between an aircraft and a ground-based system,

wherein the cost-of-transmission threshold changes in response to changes in position of the aircraft relative to the ground-based system.

11. The avionic data communication arrangement of claim 10, wherein the established communication channel is selected from a group comprising that comprises a cellular channel, an Ethernet channel, a WiFi channel, and a WiMax or LTE channel.

12. The avionic data communication arrangement of claim 10, wherein a switcher module is configured to determine the plurality of available communication channels.

13. The avionic data communication arrangement of claim 10, wherein the channel controller is a separate controller from the data controller.

14. The avionic data communication arrangement of claim 10, wherein the plurality of available communications channels are at the same geographical location.

15. The avionic data communication arrangement of claim 10, wherein the plurality of available communications channels are different types of communication channels.

16. The avionic data communication arrangement of claim 10, wherein the transmitter is configured to communicate the selected data between an aircraft that is stationary relative to a ground-based system.
