Abstract

A method for performing lawful intercept of mobile units in proximity to a target mobile unit is provided. A first mobile unit to target is identified. A geographical area about the first mobile unit is defined. Wireless networks record any other mobile units that enter the geographical area and report these mobile units to a law enforcement agency.

Claims

1. A method for performing lawful intercept of mobile units in proximity to a target mobile unit comprising:

identifying a first mobile unit to target, the step of identifying including specifying a geographical area; and

recording information about a second mobile unit that comes enters the geographical area.

2. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the geographical area comprises a radius about the first mobile unit.

3. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the information comprises the identity of the second mobile unit.

4. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the information comprises signaling messages of the second mobile unit.

5. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the information comprises call content of a call that the second mobile unit participates in.

6. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, the method further comprising the step of stopping the recording of information when the second mobile unit leaves the geographical area.

7. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the step of specifying a geographical area comprises specifying a geographical area when the first mobile unit powers on.

8. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, the method further comprising the step of sending the recorded information about the second mobile unit to a law enforcement agency.

9. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 8, wherein the step of sending the recorded information about the second mobile unit to a law enforcement agency comprises sending the GPS coordinates of the second mobile unit.

10. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 8, wherein the step of sending the recorded information about the second mobile unit to a law enforcement agency is done at a predetermined interval.

11. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 8, wherein the step of sending the recorded information about the second mobile unit to a law enforcement agency is done when the interception of information has concluded.

12. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the step of recording information about a second mobile unit that comes enters the geographical area comprises receiving a registration message from the second mobile unit.

13. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the step of recording information about a second mobile unit that comes enters the geographical area comprises receiving a call origination message.

14. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the step of recording information about a second mobile unit that comes enters the geographical area comprises receiving a status update from the second mobile unit.

15. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the step of recording information about a second mobile unit that comes enters the geographical area comprises recording the MIN of the second mobile unit.

16. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the step of recording information about a second mobile unit that comes enters the geographical area comprises recording the IMSI of the second mobile unit.

17. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the step of recording information about a second mobile unit that comes enters the geographical area comprises recording the MSISDN of the second mobile unit.

18. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, the method further comprising the step of modifying the geographical area when the first mobile unit changes location.

19. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 18, the method further comprising the step of removing the initial geographical area.

20. A method for performing lawful intercept of mobile units in proximity to a target mobile unit in accordance with claim 1, wherein the step of recording information about a second mobile unit that comes enters the geographical area is performed at multiple wireless networks.
