A system for and method of verifying the accuracy and integrity of the billing system used to bill subscribers to a radio telecommunications network. A computer (350) operating independently of the billing system (360) is used to generate fictional biographical and credi information for one or more virtual test subscribers (VTSs) (362-366). The information is then added to the network databse (340) as if it were actual subscriber data, and a simulation device (350) operates to act as a VTS by placing and receiving calls and performing other network calling activity. The network billing system (360) records the calling activity of the VTS, enters the records in a log, and prepares a bill for the VTS as it would for any other subscriber. Outside the system, baseline records, logs, and bills are prepared for comparison with the actual records, logs, and bills, and any differences are reported to the network operator. |
