Patent ID: 8073466

Claim:
A method for providing a mobile communication terminal with network-based location measurement by using a G-pCell database, the method comprising the steps of: (a) receiving a location measurement request signal from the mobile communication terminal by an SUPL (Secure User Plane Location) positioning center; (b) extracting a primary G-pCell candidate group from the G-pCell database by using measurement data contained in the location measurement request signal received from the mobile communication terminal; (c) extracting a secondary G-pCell candidate group from the primary G-pCell candidate group by excluding G-pCell IDs from the primary G-pCell candidate group, the G-pCell IDs having a distance equal to or larger than a predetermined value relative to location of the mobile communication terminal; (d) selecting a G-pCell ID having best pattern matching with the measurement data from the secondary G-pCell candidate group; and (e) transmitting a latitude and a longitude of the G-pCell ID selected in step (d) to the mobile communication terminal.
