Abstract

La présente divulgation concerne un procédé et un appareil de communication, un premier dispositif, un second dispositif et un support d'enregistrement. Le procédé comprend les étapes suivantes : un premier dispositif envoie des données de service à un second dispositif, les données de service étant obtenues par fusion d'au moins un élément de premières données. De cette manière, le premier dispositif effectue une fusion des premières données et envoie au second dispositif les données de service, lesquelles sont obtenues au moyen d'une fusion, de telle sorte que les exigences différenciées des premières données de différents réseaux peuvent être satisfaites.
