Method and device for managing communication channels for data exchange from an aircraft

Abstract

The invention relates to a method and a device for managing communication channels for data exchange from an aircraft (105) comprising means (115) for establishing at least one connection path betweenthe aircraft and at least one ground entity (120) with a plurality of communication channels of at least two different types. After detecting an event such as the modification of a communication channel condition or a modification of the aircraft position, a communication configuration enabling the aircraft to receive or transmit data from or to the ground entity via at least one of said communication channels is determined. The means for establishing at least one connection path are then adapted based on the communication configuration. Advantageously, the transmission of at least one datumcomprises determining the priority level of said datum and determining the type of communication channel of the connection path, the datum being transmitted if the determined type of communication channel is compatible with the priority level.

Description

technical field [0001] This invention relates to the field of avionics communications, and more particularly to methods and devices for managing channels used to exchange data from aircraft, in particular to allow digital messages to be communicated between an aircraft's information system and ground avionics via multiple communication paths. Asynchronous exchanges between the company's information systems. Background technique [0002] As aircraft have evolved, so has the need to exchange information between the aircraft and the ground. These needs relate inter alia to updating various elements of the aircraft information system, to transmitting flight information from ground stations, to transmitting maintenance information of the aircraft in order to optimize costs, and to the services provided to passengers. [0003] Two types of information exchange should be distinguished: between the aircraft and the ground, and between aircraft systems, about the aircraft or passeng...

AI Technical Summary

Problems solved by technology

[0006] The great disadvantage of the various schemes adopted for communication between the aircraft and the ground is that they do not meet the dual need of providing a single air-ground communication system for all applications on board the aircraft, with particular regard to priority and cost management; Allows the addition of new technologies such as HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access), without affecting the existing communication system, so as to accelerate the integration of these technologies
