MOBILE DEVICE LOCATING USING LONG TERM EVOLUTION SIGNALS

摘要

The described examples provide a system and methods for identifying a location of a mobile device within an indoor venue using cellular communication signals obtained while the mobile device is within the indoor venue. An array of antennas arranged within the indoor venue detects cellular communication signals transmitted by the mobile device. The detected cellular communication signals have detectable and measurable signal parameters that allow the location of the mobile device within the indoor venue and an identifier of the mobile device to be determined. The determined identifier of the mobile device may also be used to identify the mobile device subscriber. The mobile device indoor location information may be used to update an anonymized subscriber profile associated with the mobile device subscriber.

1. A method, comprising steps of:
detecting, by a plurality of antennas within an indoor venue, a mobile communication data signal transmitted by a mobile device in a time slot and a frequency sub-carrier assigned to the mobile device; measuring a signal parameter of the mobile communication data signal detected by each of the plurality of antennas in the time slot and frequency sub-carrier; using the signal parameter measured by each of the plurality of antennas, determining information identifying an approximate location of the at least one mobile device inside the indoor venue; and storing the approximate location information related to the at least one mobile device in the indoor venue in a location log associated with the mobile device with reference to the time slot and frequency sub-carrier.
