Patent

CA 2271801

An improved cellular communications system and method is disclosed which routes incoming calls to those subscribers who do not answer their page. The incoming call is routed to one of a list of alternate numbers, such as a home or work number in a public telephone system. Based upon the last known location of the subscriber within the cellular system, a particular list of such alternate numbers are tried in an effort to contact the subscriber outside the cellular network. Different lists are utilized depending upon the subscriber's last known location. In a first embodiment of the present invention, the various lists are stored in a home location register (26) for the cellular system (10) which forwards a particular list to the mobile switching center (14) servicing the subscriber. In a second embodiment of the present invention, the particular list is stored within and forwarded by a service control point (30) within an intelligent network.

L'invention concerne un système et un procédé de communications cellulaires perfectionnés permettant d'acheminer des appels entrants des abonnés qui ne répondent pas à leur appel. L'appel entrant est acheminé vers un des numéros d'une liste d'autres numéros, tels que le numéro privé ou professionnel dans un système de téléphone public. En se basant sur le dernier emplacement connu de l'abonné à l'intérieur du système cellulaire, on tente de contacter cet abonné, en dehors du réseau cellulaire, en appelant d'autres numéros d'une liste donnée. On utilise différentes listes selon le dernier emplacement connu de l'abonné. Dans un premier mode de réalisation de l'invention, on garde les différentes listes dans une mémoire (26) des positions des utilisateurs permanents destinée au système cellulaire (10) qui envoie une liste donnée au centre (14) de communication mobile desservant l'abonné. Dans un deuxième mode de réalisation de l'invention, on garde la diste donnée dans un point (30) de commande de services qui l'envoie dans un réseau intelligent.
