ABSTRACT:
In a cellular telephone system, a method for detecting and identifying a fraudulent user who cloned the cellular subscriber's electronic serial number and mobile identification number to gain unauthorized access to the cellular system. Cell sites transmit a paging signal on a control channel immediately after the cellular user establishes a voice communication. If an acknowledgement to the paging signal is received, then the cellular user currently engaged in the voice communication is fraudulent. A location of the fraudulent user can then be precisely identified by comparing a receiver signal strength indicator from several adjacent cell sites.
