identification number (MIN), a time stamp of the REGNOT, and
originating indicia identifying a cell where the REGNOT
originated are collected. First and second REGNOT records are
compared to determine if a time difference between the time
stamps of the two REGNOT records is less than the time needed
to travel between the cells identified by the originating
indicias contained in the two REGNOT records. Claim 13 is
illustrative of the claimed invention, and it reads as
follows:
13. A method for detecting cloning fraud in a mobile
telephone environment, comprising the steps of:
receiving a plurality of registration notification each
identifying a same particular mobile user; and
determining, as a function of a time of creation of each
of said plurality of registration notifications and a location
identified as the location of a mobile telephone that caused
the creation of each of said plurality of registration
notifications, whether an instance of cloning fraud has
occurred.
