Abstract

La présente invention se rapporte à un procédé de transmission de données d'interface filaire distribuée basé sur une technologie de transmission multipoint collaborative. Le procédé selon l'invention comprend les étapes suivantes : le cœur de réseau envoie une demande d'établissement de porteuse de service au nœud B évolué (eNodeB) principal, via une interface filaire S1 ; l'eNodeB principal interagit avec un ou plusieurs eNodeB collaboratifs via une interface filaire X2, et il établit une porteuse de service ; l'eNodeB principal envoie par rétroaction une réponse d'établissement de porteuse de service au cœur de réseau via l'interface filaire S1, et il réalise l'établissement de la porteuse de service ; enfin, les données de service entre le cœur de réseau et un équipement d'utilisateur sont transmises réciproquement via l'eNodeB principal et les eNodeB collaboratifs. La présente invention se rapporte d'autre part à un système de transmission de données d'interface filaire distribuée, basé sur une technologie de transmission multipoint collaborative. Le procédé et le système selon la présente invention permettent ainsi de réaliser un établissement de canaux de service ainsi qu'une transmission de données faisant intervenir une pluralité d'eNodeB, une fois que la technologie de transmission multipoint collaborative a été introduite dans le système d'évolution à long terme avancé.
