Abstract

Cette invention se rapporte à un système et à un procédé de télécommunications qui permettent de fournir à un abonné appelant (100) des informations géographiques associées à la position d'un abonné appelé (150), avant l'établissement de l'appel. Lorsque l'abonné appelant compose le numéro de répertoire (105) associé à un abonné appelé ayant bénéficié d'une portabilité ou qui possède un numéro non géographique, le central d'origine de l'appel interroge une base de données (130) pour en extraire un numéro d'acheminement pour l'abonné appelé. Ce numéro d'acheminement est utilisé par le central d'origine pour produire et transmettre des informations de position d'appelé (CPL) à l'abonné appelant avant l'établissement de l'appel. Ces informations CPL peuvent être fournies à l'abonné appelant sous la forme d'une annonce ou d'un message texte. Ces informations CPL permettent à l'abonné appelant d'estimer le coût de l'appel (longue distance ou local) et la convenance de l'appel avant l'établissement de celui-ci.
