Abstract
A mobile communication system that 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 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.
