CA 2280013

This invention proposes a new charging principle according to which the roaming leg is paid entirely by the party who forwards the call to a mobile subscriber. In an exemplary embodiment, the call is first routed to the exchange of subscriber B, who has forwarded his calls. After determining that the call is to be forwarded to a mobile subscriber C, the exchange routes the call to the gateway mobile switching center GMSC capable of making interrogations to the home location register of subscriber C. When the charging record for the call is generated, the called subscriber B is charged for the leg between the GMSC and subscriber C. Thus, subscriber C does thus not have to pay for calls addressed to subscriber B. To minimize the call costs to subscriber B, as direct a route as possible is preferably used on the leg between the GMSC and subscriber C.

L'invention concerne un principe de taxation visant à facturer entièrement la partie itinérante à l'utilisateur qui effectue un transfert d'appel vers un abonné mobile. Selon une variante, l'appel est d'abord acheminé vers le commutateur de l'abonné B, qui a transféré ses appels. Une fois établie la nécessité de transférer l'appel à un abonné mobile C, le commutateur achemine l'appel vers le centre de commutation mobile tête de ligne GMSC capable d'interroger l'enregistreur de localisation nominal de l'abonné C. Une fois établi le fichier de taxation pour l'appel, l'abonné appelé B est facturé pour la partie de communication entre le GMSC et l'abonné C, lequel n'est donc pas facturé pour les appels adressés à l'abonné B. De manière à réduire au minimum les frais d'appel liés à l'abonné B, on utilise de préférence un trajet aussi direct que possible sur la partie de communication entre le GMSC et l'abonné C.
