Method and device for discriminating positioning error using wireless LAN signal

摘要

Apparatus for determining a positioning error includes: database for storing grid cells separated by each pCell ID and WLAN environment information matched to grid cells; information receiving unit for receiving terminal WLAN environment information from mobile communication terminal; identification information checking unit for checking AP identification information included in terminal WLAN environment information; triangulating unit for calculating triangulation coordinate value by performing triangulation with AP position estimation information corresponding to AP identification information; grid cell positioning unit for selecting one or more grid cells corresponding to AP identification information and calculating grid cell coordinate value based on coordinate value corresponding to grid cell selected; and error determining unit for comparing triangulation coordinate value and grid cell coordinate value and determining whether there is positioning error in any one of triangulation coordinate value and grid cell coordinate value.

1. An apparatus for determining a positioning error, comprising:
a database for storing grid cells separated by each pilot cell identifier (pCell ID) and wireless local area network (LAN) environment information matched to the grid cells; an information receiving unit for receiving terminal WLAN environment information from a mobile communication terminal; an identification information checking unit for checking access point (AP) identification information included in the terminal WLAN environment information; a triangulating unit for calculating a triangulation coordinate value by performing triangulation with AP position estimation information corresponding to the AP identification information; a grid cell positioning unit for selecting one or more grid cells corresponding to the AP identification information and calculating a grid cell coordinate value based on a coordinate value corresponding to the grid cell selected; and an error determining unit for comparing the triangulation coordinate value and the grid cell coordinate value and determining whether there is a positioning error in any one of the triangulation coordinate value and the grid cell coordinate value.
