Method of Validating Cellular Carrier Records Accuracy
First Claim
1. A method of validating cellular device location record accuracy comprises the steps of:
- providing background information, wherein the background information includes a cellular subscriber activity record, radio communications transceiver site location information, and a plurality of technical configuration characteristics for a specified radio communications transceiver site;
wherein the radio communications transceiver site location information includes geographical location records for the specified radio communications transceiver site and adjacent radio communications transceiver sites;
wherein the specified radio communications transceiver site and the adjacent radio communications transceiver sites are associated with a cellular carrier and provides cellular service to a specified geographical region;
wherein the cellular subscriber activity record corresponds to a specified cellular device;
wherein the specified cellular device is registered with the cellular carrier;
wherein the cellular subscriber activity record indicates the specified cellular device being registered to the specified radio communications transceiver site during a specified time period;
generating a radio communications transceiver site map from the radio communications transceiver site location information;
verifying the geographical location records for the specified radio communications transceiver site and the adjacent radio communications transceiver sites as correct;
producing a nominal cellular wireless signal coverage map for the specified radio communications transceiver site from the radio communications transceiver site map with a radio frequency propagation analysis tool,wherein the nominal cellular wireless signal coverage map describes a cellular wireless signal coverage boundary around the specified radio communications transceiver site and the adjacent radio communications transceiver sites and cellular wireless signal coverage quality probability for a plurality of sub regions within the cellular coverage boundary;
wherein the radio frequency propagation analysis tool is used to determine reflection, refraction, absorption or other radio frequency modification factors affecting cellular service to the specified geographical location;
executing a plurality of coverage modification factor analysis processes on the background information in order to determine a plurality of potential cellular wireless signal coverage modification factors for the specified geographical region during the specified time period; and
generating a time-specific cellular wireless signal coverage map with a final analysis tool by modifying the nominal cellular wireless signal coverage map based on the potential cellular wireless signal coverage modification factors.

Abstract
A method of validating cellular device location record accuracy is intended to validate and refine cellular carrier records accuracy for investigation and litigation purposes. Records provided by a cellular carrier and other information are analyzed to validate or refine a possible and/or estimated location of a specified cellular device during a specified time frame. More specifically, the location of a specified radio communications transceiver cell site is verified, a nominal cellular wireless signal coverage map is produced, and various pieces of information regarding potential service disruptions during the specified time frame are analyzed in order to produce a more accurate coverage map during the specified time frame for the purpose of quantitatively defining probable or potential locations for the specified cellular device.
