Abstract

La présente invention concerne un procédé et un dispositif d'équilibrage de charge. Le procédé comprend les étapes suivantes : lorsqu'il est déterminé qu'une commutation doit être réalisée au niveau d'un utilisateur, qui appartient à un opérateur partagé quelconque, dans une seconde cellule d'un second nœud de contrôle de réseau, il peut être déterminé si une ressource de cellule inactive d'une première cellule d'un premier nœud de contrôle de réseau qu'un opérateur partagé quelconque est capable d'utiliser est plus grande qu'un seuil défini, la détermination étant exécutée selon des informations de charge relatives à la première cellule et selon des informations de configuration de ressource partagée de réseau relatives à un opérateur partagé quelconque en ce qui concerne la première cellule, et le cas échéant, l'utilisateur appartenant à un opérateur partagé quelconque est commuté de la seconde cellule à la première cellule. De cette façon, la présente invention résout le problème actuellement existant d'un équilibrage de charge imprécis rencontré lorsque la charge réelle de chaque opérateur partagé sous une cellule et les ressources de cellule que chaque opérateur partagé est capable d'occuper ne peuvent pas être déterminées avec précision selon la charge complète de la cellule, et améliore l'effet d'équilibrage de charge de la cellule.
