Abstract

L'invention concerne un système de communication mobile à portée étendue dans lequel un appel d'entrée non local, à destination d'un abonné en déplacement, peut être connecté à un réseau de communication mobile adoptant un système d'attribution de numéro non local différent. Afin de connecter un appel d'entrée à un abonné en déplacement, le système de communication mobile connecte un premier réseau de communication mobile à un second réseau de communication mobile au moyen d'un enregistreur de position d'interfonctionnement. Le premier réseau de communication mobile est le réseau auquel l'enregistreur de position locale du réseau local, où se trouve l'abonné en déplacement lorsque l'appel d'entrée est connecté à l'abonné en déplacement, attribue temporairement un numéro non local. Le second réseau de communication mobile est le réseau auquel l'enregistreur de position de porte du réseau local, où se trouve l'abonné en déplacement lorsque la position de l'abonné en déplacement est enregistrée, attribue temporairement un numéro non local. L'enregistreur de position d'interfonctionnement est utilisé pour enregistrer la position de l'abonné en déplacement itinérant et pour attribuer le numéro non local lorsque l'appel d'entrée est connecté.
