Abstract:
1. A method for approximating a geographic location corresponding to an operational event occurring on a wireless device, comprising: detecting the event occurring on the wireless device and a time the event occurred; obtaining at least one of a first set of location fix information corresponding to a first geographic position of the wireless device prior to the time of the event and/or a second set of location fix information corresponding to a second geographic position of the wireless device subsequent to the time of the event, wherein the at least one set of location fix information includes a time, horizontal location information, and horizontal velocity information; and calculating an approximate latitude and longitude of the wireless device location at the detected time that the event occurred on the wireless device based upon at least one predetermined relationship between the event time and the at least one set of location fix information, wherein calculating an approximate latitude and a longitude of the event further comprises determining a validity of at least one of the first set of location fix information and/or the second set of location fix information, wherein determining validity further comprises at least one of: determining that a time difference between the time of the event and a time of fix of at least one of the first set of location fix information and/or the second set of location fix information is less than or equal to a predetermined time threshold; and determining that a distance traveled by the wireless device between the time of the event and the time of fix of at least one of the first set of location fix information and/or second set of location fix information is less than or equal to a predetermined distance threshold.
