POSITION ESTIMATING SYSTEM AND METHOD OF PORTABLE TERMINAL

摘要

PURPOSE: A location determination system of a portable terminal and method thereof are provided to promote positioning accuracy using virtual APs(Access Point) by creating the virtual APs. CONSTITUTION: A data transmission and reception module(11) of a location determination server(10) communicates with a predetermined portable terminal. A virtual AP creation module(12) of the location determination server includes a virtual AP creation function including virtual location information and virtual terminal information. A DB(DataBase) search module(13) of the location determination server extracts and confirms the predetermined data stored in a DB server(20). A location calculation module(14) of the location determination server calculates the location of the portable terminal. The DB server stores the location information and real AP information.
