Abstract

La présente invention concerne un procédé et un appareil de distribution de données pour de multiples technologies d'accès radio desservant un équipement d'utilisateur, le procédé consistant à : obtenir les informations de bande passante de liaison de chaque technologie d'accès radio et la quantité de données envoyées sur la liaison de chacune des technologies d'accès radio ; déterminer la liaison de la technologie d'accès radio en attente d'être utilisée selon les informations de bande passante de liaison de chacune des technologies d'accès radio, et la quantité de données envoyées sur la liaison de chacune des technologies d'accès radio ; et envoyer les données en attente d'émission sur la liaison de la technologie d'accès radio déterminée en attente d'être utilisée. Le mode de réalisation de la présente invention permet ainsi d'utiliser pleinement les ressources de bande passante et d'améliorer également les performances du système.
