Calling party pays system bypass

Abstract

Landline facilities are linked to a wireless mobile network for calling party pays (CPP) calls to mobile stations. In response to placement of a telephone call to a CPP subscriber station, a land line network data base is accessed to obtain a call processing record for the called station that is indicative that the called station subscribes to CPP service. Based on the call processing record, a determination is made as to whether the call is be accorded exception status from CPP service. If the call is to receive such exception status, a signaling message is transmitted to the mobile switching center (MSC) for the called subscriber station. The signaling message includes the calling station telephone number in altered form. The MSC, upon detection of the altered telephone number, effectively recognizes the call as a normal call. The MSC will complete the call to the called party and establish in the called party subscriber's billing record assessment of air time charges for the call to the called party. If the called mobile station is in the vicinity of a “visiting” MSC, the latter will receive the signaling message as relayed from the subscriber's MSC. If the call is not entitled to CPP exception status, the telephone number of the calling party will not be altered in the signaling message.
