Method and System for Providing Realtime Traffic Information by Using Location Based Services

PURPOSE: A method and a system for supplying information in real time by using a location based service are provided to supply an accurate traffic information by supplying recent traffic information in real time. CONSTITUTION: A system for supplying information in real time by using a location based service(LBS) includes a mobile communication terminal(110), a mobile communication network(120), a WAP(Wireless Application Protocol) gateway(180), a position determination server(140) and a path guide service server(160). The mobile communication terminal(110) is provided with a predetermined Web browser to transmit navigation data received from at least one global positioning system(GPS) satellite through a mobile communication network and to receive the traffic information service through the wireless Internet connection. The mobile communication network(120) processes the call to connect the wireless Internet and includes the radio access network(RAN) and mobile switching center(MSC) to transceive the navigation data. The WAP gateway(180) co-operate the mobile communication network with the Internet by performing the conversion of the communication code or the conversion of protocol between the mobile communication network and the wireless Internet. The position determination server(140) calculates the coordinate of the mobile communication terminal by receiving the navigation data transmitted from the mobile communication terminal(110). And, the path guide service server(160) is provided with the LBS platform for supplying the shortest time path changed in real time to the mobile communication terminal(110) by receiving the coordinate from the position determination server(140).
