Abstract

A wireless aircraft network includes a plurality of aircrafts having transceiver devices for transceiving wireless communication, a plurality of ground-based network stations having transceiver devices for transceiving wireless communication, and a network operator station configured to store location data regarding the current geographical location of the plurality of aircrafts in a location data table of the network operator station and to determine a most efficient network path for each of the plurality of aircrafts to one of a plurality of ground-based network stations depending on the current geographical location of the plurality of aircrafts and the geographical location of the plurality of ground-based network stations.

Claims

1. A wireless aircraft network, comprising:

a plurality of aircrafts having transceiver devices for transceiving wireless communication;

a plurality of ground-based network stations having transceiver devices for transceiving wireless communication; and

a network operator station configured to store location data regarding the current geographical location of the plurality of aircrafts in a location data table of the network operator station and to determine a most efficient network path for each of the plurality of aircrafts to one of a plurality of ground-based network stations depending on the current geographical location of the plurality of aircraft and the geographical location of the plurality of ground-based network stations.

2. The wireless aircraft network according to claim 1, wherein the network operator station is further configured to provide the determined most efficient paths to each of the plurality of aircrafts as route discovery information.

3. The wireless aircraft network according to claim 2, wherein the plurality of aircrafts is configured to connect to other aircraft and/or the plurality of ground-based network stations according to the provided route discovery information.

4. The wireless aircraft network according to claim 1, further comprising:

one or more satellites configured to provide satellite communication between the plurality of aircrafts and the ground-based network stations.

5. The wireless aircraft network according to claim 1, wherein the ground-based network stations comprise one or more seaborne vessels.

6. A method for wirelessly connecting aircraft, comprising:

receiving location data regarding the current geographical location of a plurality of aircrafts in a network operator station;

updating a location data table of the network operator station according to the received location data;

reading out the current geographical locations of the plurality of aircrafts from the location data table and determining a most efficient path for each of the plurality of aircrafts to one of a plurality of ground-based network stations depending on the read out current geographical locations of the plurality of aircrafts and the geographical locations of the plurality of ground-based network stations in the network operator station;

providing the determined most efficient paths to each of the plurality of aircrafts as route discovery information for an aircraft ad-hoc network; and

connecting one or more of the plurality of aircrafts in an aircraft ad-hoc network according to the provided route discovery information.

7. The method according to claim 6, further comprising:

scheduling the transmission of aircraft related communication items depending on the provided route discovery information.

8. The method according to claim 7, wherein, if it is determined that there is currently no path between one of the plurality of aircrafts and one of the ground-based network stations, the transmission of aircraft related communication items is scheduled to be withheld until it is determined that a path between the respective aircraft and the respective ground-based network station is available.

9. The method according to claim 7, wherein, if it is determined that there is currently no path between one of the plurality of aircrafts and one of the ground-based network stations, only transmission of mission-critical aircraft related communication items is scheduled to be performed over satellite communication.

10. A network operator station for an aircraft ad-hoc network, the operator station comprising:

a location management module configured to receive location data regarding the current geographical location of a plurality of aircrafts and to update a location data table according to the received location data; and

a control module configured to read out the current geographical locations of the plurality of aircrafts from the location data table, to determine a most efficient path for each of the plurality of aircrafts to one of a plurality of ground-based network stations depending on the read out current geographical locations of the plurality of aircrafts and the geographical locations of the plurality of ground-based network stations, and to provide the determined most efficient paths to each of the plurality of aircrafts as route discovery information for the aircraft ad-hoc network.

11. The network operator station according to claim 10, wherein the network operator station is configured to determine and provide the most efficient paths according to the location-aided routing protocol (LAR), the optimized link state routing protocol (OLSR), the ad-hoc on demand distance vector routing protocol (AODV), the temporally-ordered routing algorithm (TORA), or the zone routing protocol (ZRP).

12. The network operator station according to claim 10, further comprising:

a transceiver module configured to wirelessly transmit the route discovery information to one or more of the plurality of aircrafts.

13. The network operator station according to claim 10, wherein the network operator station is connectable to one or more ground stations via a wirebound ground link, and wherein the control module is configured to provide the determined most efficient paths to the one or more ground stations as route discovery information for the aircraft ad-hoc network.
