SYSTEM AND METHOD FOR BILLING IP-BASED WIRELESS TELECOMMUNICATIONS IN A CONVERGED NETWORK

摘要

A system and method for collaborating with a billing system is provided foruse in a converged telecommunication network that includes a cellulartelephone network and an IP-based network. During an IP-based callregistration process, a mobile device communicates with a network controllerover the IP-based network. The network controller accesses a database with theinformation provided by the mobile device and subsequently overloads valuesfor an existing field in a call detail record (CDR). Upon completion of thecall over the IP-based network, the network controller communicates theoverloaded version of the CDR to an MSC which generates the final CDR that isused for billing. Any appropriate field of the CDR can be selected foroverloading, such as for example an existing CGI record field from the CDR.
