Abstract

Cette invention se rapporte à un système de communication (100) et à un procédé, qui servent à faire sonner des téléphones câblés (114) et des téléphones sans fil (116) pour ainsi dire simultanément. Ce système de communication (100) comprend un réseau téléphonique public commuté (PSTN) (102) qui fournit les services par câble d'un téléphone câblé (114), et un centre de commutation de service mobile (MSC) (104) couplé au réseau PSTN (102). Un enregistreur de localisation nominal (HLR) (106) est relié au centre MSC (104). Une station émetteur/récepteur de base (BTS) (108) est reliée au centre MSC (104). Une connexion de services d'accès commutés (110) relie le centre MSC (104) au téléphone câblé (114). La demande d'appel est reçue par le centre MSC (104). Un jeu de téléphones dont la sonnerie doit être déclenchée, qui contient à la fois une téléphone câblé (114) et un téléphone sans fil (116), est déterminé sur la base de l'enregistreur HLR (106). La sonnerie de chacun des téléphones du jeu ainsi déterminé est déclenchée pour ainsi dire simultanément. Le traitement de l'appel est transféré au premier téléphone qui répond.
