Method for tracking physical localization of cellular devices in mobile communication networks and the system thereof

A method of tracking a physical location of a user equipment (UE) in a mobile communication network, the method comprising:

• generating a specific traffic pattern by generating voice and short message service (SMS) traffic and tracking a radio network traffic identifier (RNTI) of a target UE using fingerprinting based on the specific traffic pattern;
• fixing the RNTI of the target UE and continuously receiving scheduling information on an uplink signal transmitted from the target UE by decoding a downlink control information (DCI) message transmitted from a base station;
• tracking a physical location by monitoring the uplink signal of the target UE based on the scheduling information;
• and
• controlling the uplink signal transmitted from the target UE by manipulating the DCI message in a radio channel based on the RNTI of the target UE and a configuration of the base station after tracking the RNTI of the target UE.

A system for tracking a physical location of a user equipment (UE) in a mobile communication network, the system comprising:

• a tracking unit configured to generate a specific traffic pattern by generating voice and short message service (SMS) traffic and to track a radio network traffic identifier (RNTI) of a target UE using fingerprinting based on the specific traffic pattern;
• a signal receiver configured to fix the RNTI of the target UE and to continuously receive scheduling information on an uplink signal transmitted from the target UE by decoding a downlink control information (DCI) message transmitted from a base station;
• and
• a location tracking unit configured to track a physical location by monitoring the uplink signal of the target UE based on the scheduling information, and
• further comprising:
• a signal controller configured to control the uplink signal transmitted from the target UE by manipulating the DCI message in a radio channel based on the RNTI of the target UE and a configuration of the base station.
