Abstract

La présente invention se rapporte à un procédé et à un dispositif de configuration automatique d'une station de base. Le procédé et le dispositif selon l'invention ont pour objectif d'améliorer l'efficacité d'exécution d'une procédure de configuration, et de réduire la complexité de la procédure de configuration ainsi que le taux d'erreurs de configuration. Le procédé selon l'invention comprend l'étape suivante : dans un système, un OMC remplace un serveur DHCP. De cette manière, une station de base peut ne pas passer par le serveur DHCP, et obtenir un paramètre IP directement de l'OMC. En conséquence, la procédure de configuration IP de la station de base se trouve simplifiée, l'efficacité d'exécution de la procédure de configuration est améliorée, et la complexité d'exécution de la procédure de configuration est réduite. De plus, comme une interruption de la liaison de communication, qui serait susceptible d'être induite par une incohérence entre le paramètre IP configuré par le serveur DHCP et le paramètre IP configuré par l'OMC, est évitée, le taux d'erreurs de configuration est réduit de manière efficace et les performances du système sont renforcées.
