Abstract: Disclosed are a method and a system for providing a mobile communication terminal with network-based location measurement by using a G-pCell database. The method and system are advantageous in that, when a mobile communication system employs a network-based location measurement scheme, the influence of repeaters is reduced to improve the positioning stability and measurement accuracy and provide more stable location-based services.

Abstract: There is provided a system for detecting a location of a mobile station (MS) by using a pilot strength measurement message (PSMM) in a mobile communication system providing a location-based service in a mobile communication network, comprising: a position determination entity (PDE) for detecting the location of the mobile station, collecting PSMM information from the mobile station, the location detection of which is required, and obtaining the location of the mobile station by using collected PSMM information.

Abstract: The method for positioning a mobile terminal in a GPS satellite-invisible area by using a mapping server including the mobile terminal, a location detector, a PDE and a database, comprising: (a) obtaining a reference pilot signal of a base station or a repeater and a LD pilot signal from the location detector; (b) transmitting information on the reference pilot signal or the LD pilot signal to the PDE by using a PSMM, if a strength of the reference pilot signal or the LD pilot signal is determined to be larger than a prescribed value; (c) calculating a pseudo noise code phase value per chip from the PSMM; (d) transmitting the pseudo noise code phase value to the LD mapping server, if the pseudo noise code phase value calculated at step (c) is determined to be a pseudo noise code phase value served for a location detection; and (e) obtaining a location information of the mobile terminal by using the pseudo noise code phase value transmitted at step (d).
