METHOD AND SYSTEM FOR PROVIDING LOCATION MEASUREMENT OF NETWORK BASED TO MOBILE COMMUNICATION TERMINAL BY USING G-PCELL DATABASE ACCORDING TO LOCATION

Disclosed is a system and method for providing a mobile ammunication 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 ammunication terminal when a location measurement request signal is received from the mobile ammunication terminal, and determining a location of the mobile ammunication terminal by using a G-pCell pattern matching algorithm when the number of base stations neighboring the mobile ammunication terminal, detected by parsing the base station signal, is less than the stored number of neighboring base stations awresponding to the location of the base station, disatvered 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 tri- angulation to position a mobile ammunication terminal acamiing to a rough location of the mobile ammunication terminal, thereby further improving the accuracy of location measurement. L'invention concerne un système et un procédé permettant de disposer d'un terminal de communication mobile avec une mesure de position à base de réseau selon des positions au moyen d'une base de données de G-pCell. Le système comprend un NPS pour mémoriser une base de données de stations de base voisines et une base de données de G-pCell; et un SPC pour détecter la position d'une station de base en analysant un signal de station de base reçu du terminal de communication mobile lorsqu'un signal de requête de mesure de position est reçu du terminal de communication mobile, et déterminer une position du terminal de communication mobile en utilisant un algorithme d'adaptation de motif de G-pCell lorsque le nombre de stations de base voisines du terminal de communication mobile, détectées en analysant le signal de station de base, est inférieur au nombre de stations de base voisines mémorisées correspondant à la position de la station de base, découvert en utilisant la base de données de stations de base voisines.
