(EN) CELLULAR-NETWORK BASED CONTROL OF VEHICLE-TO-VEHICLE COMMUNICATION
(FR) COMMANDE DE COMMUNICATION ENTRE VÉHICULES UTILISANT UN RÉSEAU CELLULAIRE
Abstract
(EN)
A vehicle-to-vehicle communication device (100; 100') is provided with access to a cellular network (200, 210). The cellular network (200, 210) implements at least a first radio technology. The vehicle-to-vehicle communication device (100, 100') further supports a second radio technology for vehicle-to-vehicle communication. For controlling vehicle-to- vehicle communication by the second radio technology, data from the cellular network (200, 210) are provided to the vehicle-to-vehicle communication device (100, 100'). For example, such data may be derived from presence or mobility information available in the cellular network (200, 210). On the basis of the data from the cellular network (200, 210), the vehicle- to-vehicle communication device (100, 100') sets at least one control parameter of vehicle-to- vehicle communication by the second radio technology, e.g., a rate of sending a message or a transmission power utilized by the second radio technology.

(FR)
L'invention concerne un dispositif de communication entre véhicules (100; 100') qui est pourvu d'un accès à un réseau cellulaire (200, 210). Le réseau cellulaire (200, 210) met en œuvre au moins une première technologie radio. Le dispositif de communication entre véhicules (100, 100') prend également en charge une deuxième technologie radio pour la communication entre véhicules. Pour effectuer la commande de la communication entre véhicules par la deuxième technologie radio, les données provenant du réseau cellulaire (200, 210) sont transmises au dispositif de communication entre véhicules (100, 100'). Par exemple, ces données peuvent être dérivées d'informations liées à une présence ou à une mobilité disponible dans le réseau cellulaire (200, 210). En fonction des données provenant du réseau cellulaire (200, 210), le dispositif de communication entre véhicules (100, 100') définit au moins un paramètre de commande de communication entre véhicules par la deuxième technologie radio, par exemple un débit d'envoi d'un message ou une puissance de transmission utilisée par la deuxième technologie radio.
