Abstract

Les modes de réalisation de la présente invention concernent un procédé et un dispositif de réglage de paramètres de couverture réseau, le procédé consistant en: la réception par une première station de base d'un ensemble de paramètres de couverture réseau envoyé par un premier dispositif OAM; en fonction d'au moins un ensemble de paramètres de couverture réseau, de la charge de la cellule de desserte de la première station de base, de la répartition des équipements utilisateur dans la cellule de desserte de la première station de base, et de la répartition des équipements utilisateur dans la cellule de desserte d'une seconde station de base, la détermination et le réglage, par la première station de base, des paramètres de couverture réseau en cours d'utilisation, la cellule de desserte de la seconde station de base étant une cellule de desserte adjacente à la cellule de desserte de la première station de base; la détermination, par la première station de base, de paramètres de couverture réseau cibles, et le réglage par la première station de base des paramètres de couverture réseau en cours d'utilisation aux paramètres de couverture réseau cibles. Les modes de réalisation de la présente invention améliorent les performances de couverture réseau.
