Method for routing data between at least one guided vehicle and a ground network
First Claim
1. A method for routing data between at least one guided vehicle and the ground network, wherein the vehicle moves on a track between at least a first and a second communication terminal disposed on the ground along the track, and wherein the terminals exchange data streams between a ground network and at least one routing module on board the vehicle, the method which comprises:
- periodically carrying out a transmission quality measurement for a first signal between the first terminal and the routing module;
periodically carrying out a transmission quality measurement for a second signal between the second terminal and the routing module;
periodically carrying out a measurement of an available data throughput rate for the first signal between the ground network and the routing module;
periodically carrying out a measurement of an available data throughput rate for the second signal between the ground network and the routing module;
periodically determining a routing path for at least a portion of the data between the ground network and the routing module by at least one of the communication terminals if the routing path has a measured signal quality higher than a predetermined threshold and a data throughput rate higher than a predetermined threshold; and
subdividing the routing path into several simultaneous and distinct data paths between the routing module on board the vehicle and the ground network, while the vehicle is moving, each having a bandwidth dependent on values measured by their transmission quality and their minimum guaranteed throughput rate.

Abstract
A method for routing data between at least one guided vehicle and a ground network, wherein said vehicle moves on a track between at least a first and a second communication terminal arranged on the ground along the track. The terminals are capable of exchanging data streams between a ground network and at least one routing module onboard the vehicle. A transmission quality measurement for a first signal between the first terminal and the routing module is carried out periodically, a transmission quality measurement for a second signal between the second terminal and the routing module is carried out periodically, a measurement of the available data flow rate for the first signal between the ground network and the routing module is carried out periodically, a measurement of the available data flow rate for the second signal between the ground network and the routing module is carried out periodically, a routing path for at least a portion of the data between the ground network and the routing module is also periodically determined via at least one of the communication terminals if it has a measured signal quality higher than a predetermined threshold and a data flow rate higher than a predetermined threshold.
