Abstract
(EN) A network interworking system is provided for connecting a voice call between a mobile terminal in a wireless packet network that provides VoIP service and a mobile terminal in a mobile communication network that provides circuit-switched service. A home location register (HLR) registers therein location information of terminals and a subscriber profile. A packet switch or a mobile switching center (MSC), in which a calling terminal is located, transmits a call connection request to a location of a called terminal, detected through the HLR, upon receiving an origination message including a terminal identifier of the called terminal. An MSC or a packet switch, in which the called terminal is located, transmits a message for voice call connection to the called terminal upon receiving the call connection request for the called terminal.
(FR) L'invention concerne un système d'interfonctionnement de réseaux pour la connexion d'un appel vocal entre un terminal mobile dans un réseau sans fil à commutation de paquets fournissant un service VoIP et un terminal mobile dans un réseau de communication mobile fournissant un service à commutation de circuit. Un enregistreur de localisation nominal (HLR) enregistre une information de localisation de terminaux et un profil d'abonné. Un commutateur par paquets ou un commutateur de service mobile (MSC) dans lequel un terminal d'appel est localisé transmet une demande d'établissement d'appel à la localisation d'un terminal appelé, détecté par le HLR, après réception d'un message d'origine comprenant un identifiant du terminal appelé. Un MSC ou un commutateur par paquets dans lequel le terminal d'appel est localisé transmet un message d'établissement d'appel vocal au terminal appelé après réception de la demande d'établissement d'appel pour le terminal appelé.
