Abstract

La présente invention concerne un procédé, un dispositif et un système de puissance d'optimisation automatique d'une station de base. La mise en œuvre du procédé consiste à : surveiller un indice de performances de réseau, et si l'indice ne satisfait pas à une norme, envoyer des informations d'invite et attendre en vue de confirmer que l'indice de performances ne satisfait pas à la norme du fait d'un défaut de non-optimisation de paramètre de puissance ; si l'indice de performances ne satisfait pas à la norme du fait d'un défaut de non-optimisation de paramètre de puissance et que l'indice de performances ne satisfait toujours pas à la norme une fois éliminé le défaut de non-optimisation de paramètre de puissance, obtenir la charge actuelle et des informations de cellule adjacente de la station de base à optimiser ; et mettre en œuvre une optimisation de puissance pour la station de base à optimiser en fonction de la charge actuelle et des informations de cellule adjacente. Au moyen dudit procédé, une optimisation de puissance automatique peut être obtenue, l'influence résultant d'une intervention manuelle peut être réduite, et l'efficacité et la précision de l'optimisation de puissance sont améliorées.
