  • Methods and systems for deriving seed position of a subscriber station in support of unassisted GPS-type position determination in a wireless communication system
    Patent number: 9194957
    Abstract: In a method and system for deriving a seed position of a subscriber station in a wireless communications system in supporting unassisted GPS-type position determination is provided, the subscriber station receives overhead messages from the wireless communications system, and derives the seed position from the parameter values. The subscriber station may use a data structure in its memory and map possible parameter values to corresponding positions that may serve as the seed positions.
    Type: Grant
    Filed: September 13, 2012
    Date of Patent: November 24, 2015
    Assignee: QUALCOMM Incorporated
    Inventors: Douglas Neal Rowitch, Chang S. Row, Ann Yun-En Tien, Sanjeev Khushu
