Abstract
A cellular phone call management system using a microprocessor-controlled remote card reader interface for a cellular telephone system to record calls onto a card as they are placed or received. A microprocessor reads information from a card placed in the remote card reader and ensures the card is valid. The cellular telephone's transceiver logic bus is monitored to determine the transaction information of a call as it is placed or received. After the call is completed, the call transaction information is recorded on the card. When all calls are complete, the card is placed in a host card reader attached to a host computer where the call transaction information is read from the card, processed, and written to a host storage device. The call transactions may then be analyzed and reports may be generated and printed by host computer software.
