Abstract

L'invention concerne un procédé pour réaliser un transfert d'appel orienté de téléphones mobiles Bluetooth, ainsi que les dispositifs associés comprenant des téléphones mobiles Bluetooth et une passerelle Bluetooth. La passerelle Bluetooth établit une connexion avec le réseau de téléphonie fixe par des lignes téléphoniques. Les téléphones mobiles Bluetooth sont dotés de la fonction Bluetooth et des fonctions cellulaires habituelles. Ce procédé comprend les opérations suivantes: les téléphones mobiles Bluetooth envoient des demandes pour accéder à la passerelle; la passerelle indique aux téléphones mobiles Bluetooth son numéro de téléphone; les téléphones mobiles Bluetooth enregistrent le service de transfert d'appel en cas de ligne occupée vers le réseau de téléphonie mobile; les téléphones mobiles Bluetooth informent la passerelle de l'appel en cours par l'envoi d'un signal d'occupation au réseau de téléphonie mobile lorsque les téléphones mobiles Bluetooth sont appelés de l'extérieur; le réseau de téléphonie mobile transfert l'appel entrant à la passerelle; la passerelle envoie l'appel entrant aux téléphones mobiles Bluetooth. Ce procédé permet aux téléphones mobiles Bluetooth de commuter en continu entre le réseau de téléphonie mobile et le réseau de téléphonie fixe. La qualité d'appel peut-être améliorée et la taxe peut être réduite de la taxe d'appel des téléphones cellulaires en une taxe de transfert d'appel lorsque les téléphones mobiles Bluetooth établissent une communication par le réseau de téléphonie fixe.
