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.
