Abstract

La présente invention concerne un procédé et un système de déclenchement de service permettant, d'une part de récupérer une information étendue de déclenchement de service qui ne peut pas s'obtenir de façon fixe à partir d'un message de demande initiale de communication envoyé par un producteur de message par l'intermédiaire d'une unité de récupération des informations de déclenchement de service, d'autre part de prend l'information étendue de déclenchement de service et la compare à des critères de filtrage de déclenchement de service, et enfin exécute une fonction de déclenchement de service en fonction du résultat de la comparaison. L'invention permet ainsi d'exécuter la fonction de déclenchement de service pour connaître le sens de l'appel de service en fonction de l'information étendue de déclenchement de service qui ne se présente pas de façon fixe dans le message de demande initial du protocole d'ouverture de session ou 'SIP' (Session Initiation Protocol) envoyé par l'utilisateur.
