Abstract

La présente invention concerne un procédé et un dispositif de transmission de données, et un support de stockage informatique. Le procédé comprend les étapes suivantes : un module de plan utilisateur de passerelle configure une étiquette de données en vue de la transmission d'un paquet de données de liaison descendante, l'étiquette de données étant utilisée pour étiqueter une session à laquelle appartient le paquet de données de liaison descendante; et le module de plan utilisateur de passerelle transmet à un terminal utilisateur le paquet de données de liaison descendante portant l'étiquette de données, un élément de réseau entre le module de plan utilisateur de passerelle et le terminal utilisateur transmettant le paquet de données de liaison descendante sur la base de l'étiquette de données.
