Abstract
A method for classifying calls placed from a mobile station by a subscriber to facilitate creation of an invoice record. When placing a call from the mobile station, the subscriber dials a predetermined prefix associated with a particular invoice code to identify the call as belonging to a particular invoice cost group that corresponds to the invoice code. When the invoice record is generated, all calls for which prefixes were dialed and that were placed by the subscriber from the mobile station, are automatically placed in appropriate invoice cost groups in accordance with the invoice codes of the prefixes.
