Abstract

Des modes de réalisation de la présente invention concernent un procédé et un dispositif permettant de transmettre, de transporter et de recevoir des données, ainsi qu'un procédé et un dispositif permettant de construire un réseau local. Le procédé de transport de données comprend les étapes consistant à : attribuer des adresses sur le réseau local à des équipements utilisateur (UE) appartenant à la même station de base ; recevoir les données transmises par un UE source, ces données contenant une adresse de réseau local cible ; transmettre les données à l'UE cible correspondant à l'adresse de réseau local cible sur la base de l'adresse de réseau local cible. Selon les modes de réalisation de la présente invention, il est possible d'attribuer des adresses de réseau local à des UE via un nœud B évolué (eNB). De cette manière, l'UE source peut transmettre directement les données à l'UE cible via l'eNB sans avoir à accomplir d'opération de transfert des données transmises depuis l'UE source via un cœur paquet évolué (EPC). Ceci permet d'économiser les ressources de routage de l'EPC et de réduire la dépendance envers l'EPC.
