Abstract

La présente invention porte sur un procédé, un dispositif et un système de commutateur local. Dans un mode de réalisation de la présente invention, il est déterminé si un terminal appelant et un terminal appelé reçoivent le service par la même station de base (BS) ou non. Si le service leur est fourni par la même BS, la requête transportant le paramètre que requiert le commutateur local réalisé par la BS est transmise à la BS. La requête transportant le paramètre que requiert le commutateur local réalisé par la BS envoyée par un contrôleur de réseau radio (RNC) est reçue. Le commutateur local de la BS est configuré selon ledit paramètre. La requête de libération de la configuration de commutateur local de BS, qui transporte le paramètre requis pour libérer la BS, est reçue en provenance du RNC. Le commutateur local de la BS correspondante est libéré selon ledit paramètre.
