PURPOSE: A method for tracking a real-time position using a main memory database management system and a reservation execution function is provided to use the main memory database system, and to supply the reservation execution function, thereby reducing system load and remarkably improving speed. CONSTITUTION: A position tracking server searches position tracking reservation information satisfying a time condition from a position tracking DB(S301). The server extracts a position tracking-targeted user from the searched information, and performs a position tracking process(S302,S303). The server transmits a mobile communication user number to a position processing server, and requests the position processing server to search position information(S304). The position processing server searches a position by using MIN values of client lists, and updates a position DB(S305,S306). The position tracking server receives position information of a searched client, and stores the information in the position tracking DB as mobile path information(S307). |
