Abstract

A method of configuring communications management on board an aircraft comprising the implementation of a mechanism for electing a master equipment item in a network of computer equipment items in charge of aircraft-ground communications of the aircraft and of configuring communication management according to said master equipment item. The method enables the applications in charge of the aircraft-ground communications to be distributed between the networked computer equipment items.

Claims

1. A method of configuring communications management on board an aircraft comprising:

detecting a communication management configuration event;

exchanging information relative to at least one election criterion for electing a master equipment item in a network of computer equipment items in charge of aircraft-ground communications of the aircraft;

determining a master equipment item according to said exchanged information; and

configuring communication management according to said determined master equipment item.

2. A method according to claim 1, wherein said event is at least one of:

electrical powering on of the aircraft;

a connection to said network of a computer equipment item in charge of aircraft-ground communications of the aircraft; and

a disconnection from said network of a computer equipment item in charge of aircraft-ground communications of the aircraft.

3. A method according to claim 1, wherein at least one of said items of information exchanged comprises at least one or one of:

an item of priority data respectively associated with the computer equipment items connected to said network;

a network address respectively associated with the computer equipment items connected to said network; and

an override message from a communication management authority.

4. A method according to claim 3, wherein the network addresses of the equipment items are taken into account to arbitrate between items of equipment associated with the same priority data.

5. A method according to claim 3, in which when an override message from a communication management authority is exchanged, the equipment item associated with said message is determined as being the master equipment item.

6. A method according to claim 1, further comprising deactivating at least one aircraft-ground communication service further to detecting said event.

7. A method according to claim 1, wherein said configuring comprises sending, by at least one equipment item of said network and to said determined master equipment item, at least one message relative to a type of communication handled by said equipment item.

8. A method according to claim 7, wherein said communication type identifies a communication available at said equipment item, said configuring further comprising activating said communication available at said equipment item.

9. A method according to claim 8, further comprising deactivating at least one other communication equivalent to said activated communication, said other communication being available at another equipment item of said network.

10. A method according to claim 7, wherein said communication type identifies a category of messages, said configuring comprising the handling, by said determined master equipment item, of said category of messages, on behalf of the equipment items of said network.

11. A method according to claim 1 further comprising determining a backup equipment item on the basis of said exchanged information, said backup equipment item being configured to operate as a master equipment item in case of a fault with the latter.

12. A computer equipment item for managing communications on board an aircraft comprising a processing unit configured to detect a communication management configuration event, exchange information relative to at least one election criterion for electing a master equipment item in a network of computer equipment items in charge of aircraft-ground communications of the aircraft, determine a master equipment item on the basis of said exchanged information, and configure the management of communication on the basis of said determined master equipment item.

13. A communication system on board an aircraft comprising a plurality of equipment items according to claim 12.

14. An aircraft comprising a system according to claim 13.
