Abstract: PURPOSE: A location exchange method is provided to connect a wireless communication session based on location information of each telematics, thereby exchanging real time information or data. CONSTITUTION: An input unit of transmitting telematics receives network identification information of a mobile communication network assigned in a second wireless device which requests location information(305). A wireless communication multiplexing unit requests the location information to the second wireless device corresponding to the network identification information through a relay server(310). A location relay server receives the location information of the second wireless device transmitted through a navigation program from the second wireless device(315). The second wireless device comprises the navigation program of the first wireless device. The location information of the received second wireless device is displayed. [Reference numerals] (300) Executing a navigation program in transmitting telematics; (305) Inputting network identification information of incoming telematics through an input unit of the transmitting telematics; (310) Transmitting the network identification information of the incoming telematics through a mobile communication network to a location relay server and requesting the current location information of the incoming telematics by a wireless communication multiplexing unit; (315) Extracting the current location information to the incoming telematics through the network identification information of the incoming telematics by the location relay server; (320) Transmitting the current location information of the incoming telematics to the transmitting telematics through the mobile communication network by the location relay server; (325) Measuring the current location of the transmitting telematics through a wireless position determination unit of the transmitting telematics by the navigation program; (330) Checking a local area network range through the current location information and the incoming telematics location information by the navigation program; (335,370) Yes; (340) Determining a local area network means as a wireless communication means between telematics by the navigation program; (345) Trying to connect a wireless local area network session and the incoming telematics as a wireless local area network means by the wireless communication multiplexing unit; (350,365) No; (355) Determining a wireless communication means using the mobile communication network as the wireless communication means between telematics by the navigation program; (360) Trying to connect and the wireless local area network session to a wireless communication session using the mobile communication network by the wireless communication multiplexing unit; (375) Connecting the wireless communication session between navigation programs included in the transmitting telematics and the incoming telematics; (AA) Start; (BB) Is a wireless local area network range?; (CC) Wireless communication session connection success?; (DD) End
