Disclosed is a system and method for providing a mobile communication terminal with network-based location measurement according to locations by using a G-pCell database. The system includes an NPS for storing a neighboring base station database and a G-pCell database; and an SPC for detecting the location of a base station by parsing a base station signal received from the mobile communication terminal when a location measurement request signal is received from the mobile communication terminal, and determining a location of the mobile communication terminal by using a G-pCell pattern matching algorithm when the number of base stations neighboring the mobile communication terminal, detected by parsing the base station signal, is less than the stored number of neighboring base stations corresponding to the location of the base station, discovered using the neighboring base station database. Considering that the accuracy of location measurement may be lowered when the G-pCell pattern matching algorithm is applied to the upper stories of a high-rise building in an area where high-rise buildings stand closely together, such as a downtown area, the system and method selectively uses the G-pCell pattern matching algorithm or a location measurement algorithm based on triangulation to position a mobile communication terminal according to a rough location of the mobile communication terminal, thereby further improving the accuracy of location measurement.
