Abstract: Methods and systems for profiling the locations of users of wireless communication terminals. A profiling engine may accept data points regarding a given target. Each data point may indicate a location of the target at a certain measurement time. The profiling engine may accumulate the data points relative to a periodic time scale having a pre-specified time period. The accumulation process produces a location profile of the target. The location profile may convey information regarding the tracked targets. For example, the profiling engine may use the location profile to improve the location accuracy of a target terminal that is idle for long period of time, to detect deviations from the characteristic location pattern of a target, to detect that a certain sensitive location is being visited regularly by a given target, and/or to identify connections among different targets by detecting similarities or correlations between their location profiles.

Mobile device users may also be inhibited from initiating communication sessions.

Abstract: Methods for generating more accurate location estimates are based on indicative factors. The factors are gleaned from wireless signals that were received by a wireless terminal and from other network-specific data. Each factor is probative of whether the wireless signals were received by the wireless terminal: (i) indoors versus outdoors, and/or (ii) “above-the-clutter” versus “below-the-clutter” of ambient wireless signals, and/or (iii) while moving at a certain speed classification, e.g., stationary/pedestrian versus vehicular speeds. Each factor tends to prove or disprove the particular characteristic. The result is an estimated probability, such as the probability that the wireless terminal received the signals indoors. The estimated probability is applied to the analysis of candidate locations, eliminating some candidates from further consideration. This enables computational resources to focus on the remaining higher-likelihood candidate locations and provides improved accuracy in the location estimate.
