Abstract

L'invention porte sur un procédé, un dispositif et un système de mise en œuvre d'un message d'urgence. Le procédé comprend les opérations suivantes : une fonction de commande de session d'appel mandataire (P-CSCF) (80) reçoit un message de requête envoyé par un équipement utilisateur (UE), et estime si le message de requête est un message d'urgence ou non, et envoie le message de requête à une fonction de commande de session d'appel d'urgence (E-CSCF) (82) dans le réseau courant ; la E-CSCF (82) obtient l'identifiant de centre de messages courts d'urgence (E-SC) du réseau courant et l'adresse du point de réponse de sécurité publique (PSAP) (86) du réseau courant ; la E-CSCF (82) transforme le message de requête en un message court de requête et envoie le message court de requête, l'identifiant d'appelé du message court de requête étant l'adresse du PSAP (86), et l'identifiant de centre de messages courts du message court de requête étant l'identifiant du E-SC. Avec l'invention, le message d'urgence peut être traité dans le réseau courant et le PSAP approprié peut être attribué à l'utilisateur.
