This invention relates to apparatus and methods for providing cellular mobile telecommunication service in accordance with the requirements of the Global Systems for Mobile Communications (GSM) standard. A modular switching system is provided which performs the functions of the mobile switching center plus those of a home location register, authentication center, visitor location register, and equipment identity register. The latter functions are advantageously spread among the modules of the switching system, thus avoiding the getting started cost of expensive dedicated data bases. A wireless global switching module advantageously switches mobile communications control messages among the modules of the system and between the modules and the base station systems, and terminates signaling links between the mobile switching center and the base station systems.
La présente invention porte sur un appareil et sur des méthodes servant à offrir des services de télécommunication mobile conformes aux exigences de la norme GSM (« Global Systems for Mobile Communications »). L'appareil utilise un système de commutation modulaire dont les fonctions intègrent celles d'un centre de commutation mobile, d'un registre d'installations domestiques, d'un centre d'authentification, d'un registre de localisation de visiteurs et d'un registre d'identification du matériel. Ces dernières fonctions sont réparties entre les modules du système de commutation, ce qui offre l'avantage d'éviter les dépenses élevées associées à la création de bases de données spécialisées. Un module de commutation global sans fil est utilisé pour commuter les messages de contrôle des communications mobiles entre les modules d'un système et entre les systèmes et les stations de base, et termine la liaison de signalisation entre le centre de commutation mobile et les stations de base.
