CA 2099738

This invention relates to a method and apparatus for offering wireless telecommunication service. A switch such as an automatic Private Branch Exchange(PBX), equipped to communicate with Integrated Services Digital Network (ISDN) stations sends ISDN signaling messages to and receives ISDN signaling messages from a protocol converter. The protocol converter, which also communicates with a wireless cell site, converts messages between the ISDN protocol and a protocol for communicating with the wireless cell site. The cell site sets up wireless connections to a mobile station, essentially in its prior art mode, and the PBX sets up connections to the cell site essentially in its prior art ISDN station control mode. The PBX is connected to a class 5 (central office) telecommunications switching system for establishing connections between the public switched telephone network and the PBX, or between outlets of the PBX for a call between wireless stations.

L'invention porte sur une méthode et un appareil servant à offrir des services de télécommunication sans fil. Un commutateur tel qu'un autocommutateur privé (PBX) équipé pour communiquer avec les stations d'un réseau numérique à intégration de services (RNIS) transmet des messages de signalisation RNIS à un convertisseur de protocoles et reçoit des messages de signalisation RNIS de celui-ci. Ce convertisseur, qui communique également avec un site cellulaire sans fil, convertit les messages entre le protocole RNIS et un protocole de communication avec ce site cellulaire. Ce dernier établit des connexions sans fil avec une station mobile, en utilisant essentiellement le mode courant, et le PBX établit des connexions avec le site cellulaire en utilisant essentiellement le mode de commande de station RNIS courant. Le PBX est connecté à un système de commutation de télécommunications de classe 5 (central) pour l'établissement des connexions entre lui-même et le réseau téléphonique commuté public, ou entre certaines de ses sorties pour les appels entre stations sans fil.
