Abstract

Procédé servant à remédier à un échec de communication au moyen d'une demande d'enregistrement et consistant en ce qui suit. (1) Quand une communication vocale atteint l'émulateur d'un central mobile et que cet émulateur ne possède pas les informations de localisation de l'utilisateur, le système demande au téléphone mobile de produire une mise à jour de localisation par enregistrement obligatoire; (2) le téléphone mobile reçoit le message de demande d'enregistrement basé utilisateur émanant du système et produit une mise à jour de localisation au moyen d'un message portant les informations de localisation actuelle de l'utilisateur; (3) le système reçoit une mise à jour de localisation de l'utilisateur, met à jour les informations dynamiques de celui-ci en fonction des informations actualisées que comporte le message de mise à jour de localisation et obtient la zone de localisation actuelle de l'utilisateur, ce qui permet au système de rechercher ce dernier selon les informations dynamiques obtenues. L'invention permet au téléphone mobile d'effectuer en temps une mise à jour, si nécessaire, des informations dynamiques actuelles et d'éviter l'inconvénient d'une mise à jour de localisation par ordre fixe, ainsi que d'optimiser l'arrivée de la communication pour l'utilisateur.
