Method, apparatus and system for mearsuring location based terminal by using u-pcell database

A method, an apparatus, and a system for measuring location based terminal by using u-pcell database by storing only basic data required for detecting the location of U-pcell data base and managing it. A mobile terminal(110) selects optimum U-pcell from a U-pcell database and generates and transmits location data of the optimum U-pcell. An UMTS network provides a short message service and a mobile communications service including data communications service to the mobile terminal. The U-pcell location detection server(230) receives a request of U-pcell database from the mobile terminal and receives the location data from the mobile terminal.
