Abstract:
1. A method of detecting that a device identifier that identifies a first mobile device has been used by a second mobile device to utilize telecommunication services, the method comprising: receiving a plurality of mobile-device locations associated with the device identifier, wherein the plurality of mobile-device locations describe locations at which the first mobile device and the second mobile device engaged in a communications instances; identifying a subset of locations from the plurality of mobile-device locations, from among the plurality of mobile-device locations, detecting an outlying mobile-device location that is characterized by either lacking a call relationship with any location in the subset, failing to satisfy the threshold distance, or a combination thereof, wherein the threshold distance comprises an approximate radius of the geographical grouping; and providing an unauthorized-use response when the outlying mobile-device location is detected based on an inference that the second mobile device is using the device identifier.
