Title (EN) CONFIGURATION CONTROL FOR NETWORK
(FR) CONTRÔLE DE LA CONFIGURATION D'UN RÉSEAU
Abstract:
(EN) A configuration controller (60) is provided to make changes to configuration of a communications network (10) having VNFs used in providing services to UEs. If the change could affect a service using a first VNF (30), if made while that VNF is in use, a substitute VNF (32) is instantiated corresponding to that first VNF. The first UE is transferred to use the substitute VNF instead of the first VNF. The proposed change to the configuration is made with respect to either one of these VNFs, while the service to the first UE is maintained using the other one of these VNFs. If needed all VNFs and a service area can be substituted. Thus, such configuration changes no longer need to await a quiet period when few or no UEs are attached, and enable the configuration changes to be made more rapidly, responsive to changing circumstances.
(FR) L'invention concerne un contrôleur de configuration (60) utilisé pour apporter des changements à la configuration d'un réseau de communication (10) dont des VNF sont utilisées pour fournir des services à des UE. Si le changement risque d'affecter un service utilisant une première VNF (30), s'il est apporté pendant qu'une VNF est en cours d'utilisation, une VNF de substitution (32) correspondant à cette première VNF est instanciée. Le premier UE est transféré de sorte à utiliser la VNF de substitution au lieu de la première VNF. Le changement proposé à la configuration est exécuté par rapport à l'une de ces VNF, tandis que le service au premier UE est maintenu à l'aide de l'autre de ces VNF. Si nécessaire, la substitution peut concerner toutes les VNF ainsi qu'une zone de service. Dans ce cas, de tels changements de configuration peuvent se faire sans attendre une période de calme durant laquelle un petit nombre d'UE seulement ou pas d'UE du tout sont rattachés, ce qui accélère les changements de configuration, en réponse aux changements de circonstances.
