Abstract
A method for calibrating geolocation analytic system in a wireless network includes receiving a first data set including measurement data associated with a mobile device connected to the wireless network from a first data source. A second data set comprising external geo-location data associated with the mobile device is received from a second data source. The first data set is compared to the second data set to estimate geo-location of the mobile device and to identify one or more errors using calibration function. The identified one or more errors are corrected based on the comparison.
Claims17
A method for calibrating geolocation analytic system in a wireless network, the method comprising steps of:
- receiving a first data set comprising measurement data associated with a mobile device connected to the wireless network from a first data source;
- receiving a second data set comprising external geo-location data associated with the mobile device from a second data source;
- comparing the first data set to the second data set to estimate geo-location of the mobile device and to identify one or more errors using calibration function wherein the one or more identified errors includes a calculated signal propagation delay value error;
- and
- correcting the identified one or more errors based on the comparison including providing periodic updates to propagation parameter data.
A self-calibrating geolocation analytic system in a wireless network, the system comprising:
- a predictor database configured to receive and store measurement data associated with a mobile device connected to the wireless network from a plurality of first data sources;
- an analyzing engine in communication with the predictor database and configured to retrieve from the predictor database and analyze a first data set comprising measurement data associated with the mobile device connected to the wireless network, wherein the analysis of the first data set provides an estimated location of the mobile device;
- a calibration engine comprising a processor and a memory device coupled to the processor in communication with the analyzing engine and in communication with a second data source configured to receive and store external geo-location data associated with the mobile device, the memory device containing a set of instructions that, when executed by the processor, cause the processor to:
- receive the first data set and the estimated location of the mobile device from the analyzing engine and receive a second data set comprising external geo-location data associated with the mobile device from the second data source;
- compare the first data set to the second data set to adjust the estimated geo-location of the mobile device and to identify one or more errors using the received external geo-location data wherein the one or more identified errors includes a calculated signal propagation delay value error;
- and
- correct the identified one or more errors based on the comparison including providing periodic updates to propagation parameter data.
