Abstract

L'invention concerne un procédé et un dispositif de commande de puissance de liaison montante basée sur un réseau homogène UMTS. Le procédé comprend les étapes suivantes : calculer périodiquement, par un RNC, un déséquilibre maximal entre une liaison montante et une liaison descendante (MIUD) entre une cellule de desserte et une cellule voisine avec une faible charge de liaison montante ; surveiller un rapport de mesure communiqué par un UE dans la cellule de desserte lorsque le MIUD est supérieur ou égal à un seuil prédéfini ; lorsque l'UE a besoin d'ajouter une cellule voisine, dont une charge de liaison montante est inférieure à celle de la cellule de desserte, dans l'ensemble actif, configurer une valeur cible de SIR de liaison montante pour qu'elle soit au moins supérieure au MIUD pour une liaison radio qui doit être ajoutée pour un transfert intercellulaire sans coupure de l'UE, et reconfigurer des paramètres radio d'interface radio de RRC de services de liaison montante associés ; et adapter dynamiquement la valeur cible de SIR de liaison montante de la liaison radio pour un transfert intercellulaire sans coupure de l'UE dans la cellule de desserte selon une différence maximale entre une valeur mesurée de SIR de la cellule de desserte et celle de la cellule voisine avec une charge de liaison montante inférieure à celle de la cellule de desserte et le changement du MIUD.
