SYSTEMS AND METHODS TO TRACK REGIONS VISITED BY MOBILE DEVICES AND DETECT CHANGES IN LOCATION PATTERNS

摘要

Systems and methods including mobile devices determining their location using a location determination system, such as a global positioning system. A database stores the identifiers of cells representative of predefined regions in a hierarchical grid system. The location coordinates as function of time are converted to visitation patterns of the mobile devices to the predefined regions, based on converting the coordinates to cell identifiers and searching the database to find matches between the cell identifiers representing the regions and the cell identifiers representing the mobile device locations. For example, mobile devices having similar visitation patterns can be identified and divided into two groups; and information relevant to a region is transmitted to one of the group but not another. The visitation patterns of the two group after the transmission is identified and compared to measure a difference.

1. A computing device, comprising:
at least one microprocessor; and memory storing instructions configured to instruct the at least one microprocessor to:
receive, from a first mobile device, first location data identifying coordinates of locations of the first mobile device as a function of time;convert, by the computing device, the coordinates of the locations of the first mobile device into first identifiers of geographical regions having predefined boundaries;determine, by the computing device, visitations of the first mobile device to a geographical region as a function of time based on converting of the coordinates of the locations of the first mobile device into the first identifiers of geographical regions;receive, from a second mobile device, second location data identifying coordinates of locations of the second mobile device as a function of time;convert, by the computing device, the coordinates of the locations of the second mobile device into second identifiers of geographical regions;determine, by the computing device, visitations of the second mobile device to the geographical region as a function of time based on converting of the coordinates of the locations of the second mobile device into the second identifiers of geographical regions;determine, by the computing device, a difference in visitations to the geographical region, based on
the visitations of the first mobile device to the geographical region as a function of time, andthe visitations of the second mobile device to the geographical region as a function of time.
