Abstract

Une balise (115) transmet périodiquement un signal (121) de balise, identifiable parmi d'autres signaux de balises (non illustrés) par une unité distante (113). A l'émission d'un appel, l'unité distante (113) recherche le signal (121) de balise transmis par la balise (115) et signale aux stations de base si oui ou non le signal (121) de balise est reçu par l'unité distante (113). L'état de la balise est acheminé par un matériel d'infrastructure à un centre de facturation (101), lequel vérifie indépendamment que l'unité distante (113) communique avec des stations de base représentatives de la zone locale de l'unité distante, et facture l'appel en conséquence.
