Abstract

Un système de communication servant à transmettre des données d'une première station mobile à une deuxième station mobile comprend une station de base et un dispositif de relais. La station de base est utilisée pour configurer un lien ascendant et un lien descendant de données correspondant à un premier ID de section et un deuxième ID de section respectivement et pour transmettre une clé de chiffrement de trafic aux première et deuxième stations mobiles de sorte que la première et la deuxième stations mobiles partagent la clé de chiffrement de trafic. Le dispositif de relais est couplé à la station de base et aux première et deuxième stations mobiles par communication sans fil et utilisé pour recevoir les données chiffrées par la clé de chiffrement de trafic et transférer les données de la première station mobile à la deuxième station mobile selon les ID de connexion de la première et la deuxième sans passer par la station de base.
