Abstract

A method and a system for providing a location information acquisition service in a mobile communication network are provided to prevent a bad influence on each individual privacy and the possibility of a crime by using location information by acquiring the longitudinal/latitudinal information of a location information requester's GPS mobile terminal and the longitudinal/latitudinal information of a correspondent GPS mobile terminal, analyzing the acquired information, calculating distance and direction, and providing a location information acquisition service to the requester's GPS mobile terminal by using the calculated distance and direction. A location information acquisition server acquires the longitudinal and latitudinal information of a location information requester's mobile terminal and the longitudinal and latitudinal information of a correspondent mobile terminal in real time using a satellite, obtains location information through the acquired longitudinal and latitudinal information, and stores the obtained location information in a location information DB(S201,S203). At this moment, if the requester makes a location information request signal to obtain location information of the correspondent mobile terminal(S205), the location information request signal is delivered to a main server through a BTS, a BSC, and an MSC(S207). The main server fetches the location information of the correspondent mobile terminal from the location information DB with the consent of the correspondent mobile terminal and provides it to the requester's mobile terminal through the BSC, the MSC, and the BTS(S211).
