Abstract

La présente divulgation concerne un procédé et un système d'extraction de paquets SIP souhaités au niveau d'un serveur de nœud SIB 5 [108]. La divulgation concerne un procédé dans lequel au moins un utilisateur présente une réclamation auprès d'un opérateur de réseau ; sur la base de l'au moins une réclamation reçue de la part de l'au moins un utilisateur, un opérateur de réseau prépare un fichier de configuration par l'intermédiaire d'une interface en ligne de commande d'un serveur de nœud SIB [108] ; le serveur de nœud SIB [108] correspond à un paquet SIP avec des informations dans le fichier de configuration ; si la correspondance est trouvée, le paquet SIP est stocké dans une base de données [106] connectée au serveur de nœud SIB ou faisant partie du serveur de nœud SIB [108], sinon le paquet SIP 0 n'est pas stocké.
