  • Method for masking the location of a mobile subscriber in a cellular communications network
    Patent number: 6714790
    Abstract: A method for masking a location (142) of a mobile subscriber in a cellular communications network is disclosed. The subscriber location (142) is masked by dividing a territory of cellular coverage into a grid (100) of cells (102-118) and dislocating the actual location (142) to a center of a cell (124) or to a point within a circle (140).
    Type: Grant
    Filed: December 19, 2000
    Date of Patent: March 30, 2004
    Assignee: Motorola, Inc.
    Inventors: Max Allen Heckard, Tommy Wai-Hing Tsui, Jerry Shihkuo Tang, David Jesus Garcia, Dean Paul Vanden Heuvel

  • Method for rectangular parameterization of a geographic area using a geolocation algorithm
    Patent number: 6393293
    Abstract: A method (40) for parameterizing a predetermined geographic area (12) serviced by a satellite communication system (60) into a number of equally shaped sub-partitions (22) is discloseed. The satellite communication system (60) has a processor (64, 72)for generating data elements and a memory (66, 74) for storing the data elements in data structure. The method (40) includes the step (42) of determining a total latitude side length dimension and a total longitude side length dimension of the predetermined geographic area (12) from latitude and longitude values representative of the geographic area. The steps (44) also include determining the area of a sub-partition based upon the total latitude side length, the total longitude side length, and the number of equally shaped sub-partitions. Each of the sub-partitions (22) are substantially square and have the same area.
