Abstract
(EN)
The present invention relates to a control system (CCS) having trunks to receive setup signaling messages for setting up call sessions in a communication network, means to detect that a setup signaling message corresponds to a service requiring a duplication to be happened to the originator of said setup signaling message and/or to the called subscriber/user, and a media server (MS) to duplicate and forward the content of said call session to a duplication destination (LEA) according to said duplication service detection. This call control system further comprises means for determining said media server (MS) according to the geographical region of said media server (MS), said geographical region being determined at least from a key verification relative to said setup signaling message.

La présente invention concerne un système de commande (CCS) ayant des lignes réseau pour recevoir des messages de signalisation d'établissement pour établir des sessions d'appel dans un réseau de communication, des moyens pour détecter qu'un message de signalisation d'établissement correspond à un service demandant une duplication à fournir à l'expéditeur dudit message de signalisation d'établissement et/ou à l'abonné/utilisateur appelé, et un serveur multimédia (MS) pour dupliquer et acheminer le contenu de ladite session d'appel vers une destination de duplication (LEA) conformément à ladite détection de service de duplication. Ce système de gestion d'appel comprend en outre des moyens pour déterminer ledit serveur multimédia (MS) conformément à la région géographique dudit serveur multimédia (MS), ladite région géographique étant déterminée au moins à partir d'une vérification de clé relative audit message de signalisation d'établissement.
