Methods in a wireless communication system for crime investigation, evidence generation and analysis
First Claim
1. A crime investigation method comprising:
- receiving information regarding a commission of a crime at a time period of interest and at a geographic location of interest;
after the receiving and using wireless communications analysis equipment of a mobile vehicle, measuring cellular signals in a geographic area which includes the geographic location of interest during the time period of interest;
as a result of the measuring, generating measurement data which is indicative of a parameter of the cellular signals in the geographic area;
using the measurement data, calculating a footprint map which identifies one of a plurality of communications sources which a mobile communications device is most likely to communicate with when the mobile communications device is located at a plurality of geographic locations within the geographic area during the time period of interest;
accessing cellular communications records which are indicative of communications of the mobile communications device via the cellular signals in the geographic area during the time period of interest; and
using the cellular communications records and the footprint map, providing information regarding the crime including a presence of the mobile communications device within the geographic area during the time period of interest.

Abstract
Crime investigation methods, evidence generation methods, and wireless communications system analysis methods are described. According to one aspect, a crime investigation method includes receiving information regarding a commission of a crime at a time period of interest and at a geographic location of interest, after the receiving and using wireless communications analysis equipment, measuring cellular signals in a geographic area which includes the geographic location of interest during the time period of interest, as a result of the measuring, generating measurement data which is indicative of a parameter of the cellular signals in the geographic area, using the measurement data, calculating a wireless coverage representation for the geographic area and which includes the geographic location of interest, accessing cellular communications records which are indicative of communications via the cellular signals in the geographic area, and using the cellular communications records and the wireless coverage representation, providing information regarding the crime.

13. An evidence generation method comprising:
-
identifying a geographic location of interest; identifying a time period of interest; using wireless communications analysis equipment of a mobile vehicle and during the time period of interest, measuring wireless communications signals emitted from at least one fixed-position wireless communications source of a wireless communications network in a geographic area which includes the geographic location of interest; as a result of the measuring, generating measurement data which is indicative of a parameter of the wireless communications signals in the geographic area during the time period of interest; using the measurement data, generating a footprint map which identifies the at least one fixed-position wireless communications source as a source which a mobile communications device is most likely to communicate with when the mobile communications device is located at a plurality of geographic locations within the geographic area during the time period of interest; and using the footprint map as evidence to indicate a presence of the mobile communications device within the geographic area during the time period of interest. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A wireless communications system analysis method comprising:
-
identifying a geographic area of interest to analyze wireless communications of a wireless communications system; during a time period of interest, enabling wireless communications analysis equipment of a mobile vehicle; during the time period of interest, moving the mobile vehicle and the enabled wireless communications analysis equipment throughout the geographic area of interest to analyze the wireless communications system; during the moving, measuring wireless communications signals emitted from a plurality of fixed-position communications sources of the wireless communications system at different geographic locations within the geographic area of interest; as a result of the measuring, generating measurement data which is indicative of a parameter of the wireless communications signals at the different geographic locations within the geographic area of interest during the time period of interest; communicating the measurement data to a remote computing device; and using the remote computing device, generating a footprint map which identifies one of the fixed-position communications sources which a mobile communications device is most likely to communicate with when the mobile communications device is located at selected ones of the different geographic locations during the time period of interest. - View Dependent Claims (21, 22, 23)
