Abstract

L'invention concerne un procédé de détection de clé et de réception de numéro pour un terminal dans un état d'appel. Lorsque le terminal entre dans un état d'appel, le procédé comprend les étapes suivantes : une unité d'interfonctionnement (IWU) (20) reçoit un message INFO étendu destiné à lancer la détection de clé, qui est envoyé par un serveur de protocole d'initiation de session (SIP) (10) ; et elle effectue la détection de clé et la réception de numéro pour le terminal dans un état d'appel, en fonction du message. Après la détection de clé et la réception de numéro par la IWU, le serveur SIP reçoit un message INFO étendu pour la réussite de la réception de numéro, qui est envoyé par la IWU. Le serveur SIP réalise des services indiqués par des symboles de clé détectée et de numéro reçu après qu'il a été établi que lesdits symboles contenus dans le message INFO étendu pour la réussite de la réception de numéro sont conformes aux symboles de clé nécessaires à la détection. L'invention concerne également un système de détection de clé et de réception de numéro pour un terminal dans un état d'appel. Le problème lié au fait qu'un serveur SIP ne peut pas commander à une IWU d'acquérir des événements de clé d'un terminal dans un état d'appel peut être résolu par la mise en oeuvre des procédé et système selon l'invention.
