Abstract: According to the techniques presented herein, location data from signals transmitted by a plurality of mobile wireless devices in a wireless network are obtained. For each mobile wireless device, location data time points are aggregated to generate a plurality of routines or paths of movement for each mobile wireless device within a predefined space. The predefined space is partitioned into a plurality of units and each routine of the plurality of routines is also partitioned into a plurality of subroutines or segments. For each unit, one or more subroutines within a predefined distance of a frequent subroutine are combined with the frequent subroutine, and the frequent subroutines may be displayed on a graphical interface to visualize aggregate movement of the plurality of mobile wireless devices within the predefined space. Frequent subroutines may be analyzed in an automated manner to generate notifications and alerts.

Abstract: Location data is obtained from signals transmitted by a first plurality of mobile wireless devices in a wireless network, wherein the first plurality of mobile wireless devices are moving within a predefined space, and wherein the location data comprises a plurality of location data time points, each location data time point including a timestamp, a unique mobile wireless device identifier, and location information indicating where in the predefined space an associated mobile wireless device is located. For each mobile wireless device, location data time points are aggregated to generate a set of aggregated location data for each mobile wireless device, and the set of aggregated location data is analyzed to determine characteristics corresponding to time-dependent behavior and location-specific behavior of the corresponding mobile wireless device. A user of each corresponding mobile wireless device is classified into a category of a plurality of categories based on the determined characteristics.
