ABSTRACT:
A method for foiling cellular telephone cloning by verifying subscribers of a cellular communications network is accomplished by having each subscriber provide a local telephone number, typically not their own, to the cellular telephone company and long distance carrier for each cellular telephone they own in order to verify legitimate subscribers. The verification telephone numbers provided by the subscribers are stored in respective databases and correspond to electronic serial numbers of subscriber telephones. Shortly after power-up of the cellular telephone, a subscriber either invokes an automatic dialer or manually dials the verification telephone number. A computer in the cellular network receives the subscriber's first call (containing an electronic serial number, network identification and verification telephone number) after power-up and verifies the dialed telephone number against the verification telephone number stored in the database corresponding to the electronic serial number of that cellular telephone. In response to a match, the cellular network transmits a single ring to the subscriber telephone as confirmation of a validation; otherwise a message requesting enablement of the cellular telephone is transmitted to the subscriber telephone. A similar process is implemented in the long distance carrier to verify legitimate subscribers when they travel to an area not serviced by their local cellular network.
