The present invention proposes a method for performing a call drop-back in a telecommunication system, said telecommunication system comprising at least one exchange (MSC) for switching calls between at least two subscribers (A, C) or between one of said subscribers and a message server (VMS/SN), wherein said message server (VMS/SN) is adapted to maintain a record of a plurality of previous messages intended for a called subscriber (A) and which previous messages were recorded to the message server record from a respective calling subscriber (C), wherein said method comprises the steps of: invoking (S6) a callback call from said called subscriber (A) to said calling subscriber (C) based on the information recorded in said message server record via at least one of said at least one exchange (MSC), and upon invoking said callback call, setting the system into a state enabling said called subscriber (A) to be connected back to said message server (VMS/SN) after the termination of said invoked callback call. Also, a corresponding control device as well as a network element comprising the same are proposed.
La présente invention concerne un procédé pour effectuer un rappel d'abonné ayant laissé un message dans un système de télécommunication. Ce dernier système comprend au moins un commutateur de service mobile (MSC) pour commuter les appels entre au moins deux abonnés (A, C) ou entre l'un desdits abonnés et un serveur de messages (VMS/SN). Ce serveur de messages est adapté pour conserver un enregistrement de plusieurs messages précédents s'adressant à un abonné appelé (A), lesquels messages sont enregistrés dans le serveur de messages à partir d'un abonné appelant correspondant (C). Ce procédé comprend les étapes consistant à effectuer (S6) un appel de rappel de la part de l'abonné appelé (A) vers l'abonné appelant (C) en fonction des informations enregistrées dans ledit serveur de messages, via au moins un desdits commutateurs de service mobile (MSC), puis à ce moment, de faire passer le système dans un état permettant audit abonné appelé (A) de se connecter de nouveau audit serveur de messages (VMS/SN) une fois le rappel terminé. En outre, l'invention traite aussi d'un dispositif de commande correspondant ainsi que d'un élément de réseau comprenant ce dernier.
