Wireless network or the like.

The telematics system configured as described above is provided with a telematics for providing a telematics service to a driver's vehicle, and a content providing server for providing contents to the telematics on a wireless network to which the telematics is connected. It is similar to the client server structure on the wired Internet. For example, telematics provided in a vehicle corresponds to a client on the wired internet, and a content providing server on a wireless network corresponds to a server on the wired internet.

In the conventional telematics system as described above, the telematics provided in the vehicle requests information and / or data to the content server through the wireless network, and the content server transmits the information and / or data corresponding to the request through the wireless network. It includes a problem that only one-sided information and / or data flow provided by telematics provided in a vehicle exists.

Meanwhile, in a telematics system, telematics provided in a vehicle is based on a mobile computing technology that provides portability and mobility, but includes distinctly different features from known mobile computing technologies.

For example, known mobile computing technologies have had to give up much of their computing power to provide users with portability and mobility, but since telematics is provided in a vehicle, it provides almost the same computing performance as fixed computing while ensuring portability and mobility. It is possible.

In addition, although the computing performance of telematics is almost the same as the fixed computing environment, there is a distinctive feature from the fixed computing in terms of user interface and / or resource utilization.

For example, the telematics system uses Speech Recognition in addition to key input to the information input interface to ensure the driver's safety, and the user output interface uses Text To Speech (TTS) in addition to the screen output unit.

In addition, even when outputting a sound to a driver, for example, instead of using a separate sound output device, the sound output device provided in the vehicle is shared and utilized, and the power supply is not using a battery having a limited capacity. It is possible to use a high output battery that is continuously charged through a generator provided in the vehicle.

The telematics system as described above may use various high performance computing systems and vehicles that are substantially the same as the fixed computing environment, and may provide various mobile services that could not be provided by known mobile computing technologies.

According to a preferred embodiment of the present invention, a driver of a vehicle equipped with outgoing telematics is provided with a navigation program (= an application program equipped with real-time information and / or data exchange function between telematics proposed by the present invention). (300), and inputs network identification information of the incoming telematics through the input unit 120 of the outgoing telematics (305).

When the network identification information of the incoming telematics is input through the input unit 120 of the outgoing telematics as described above, the wireless communication multiplexer 105 provided in the outgoing telematics is connected to the incoming through the mobile communication network (= first wireless communication means). The network identification information of the telematics is transmitted to the location relay server 170 on the wireless network, and the current location information of the incoming telematics is requested from the location relay server 170 (310).

According to a preferred embodiment of the present invention, the wireless positioning unit 140 provided in the incoming telematics periodically generates the location information of the incoming telematics to present the location information D / B 175 provided in the location relay server 170. In this case, the location relay server 170 extracts the current location information of the most recently updated destination telematics from the location information D / B 175 based on the network identification information of the incoming telematics (315). .

According to another exemplary embodiment of the present invention, the wireless positioning unit 140 provided in the incoming telematics generates the location information of the incoming telematics only by a position measurement command, thereby providing the location information D / B 175 provided in the location relay server 170. In this case, the location relay server 170 requests wireless positioning of the current location information through the mobile communication network based on the network identification information of the incoming telematics, and transmits the current location information to the incoming telematics. The radio location unit 140 determines the radio location request as a location measurement command, measures the current location of the corresponding telematics, generates location information on the current location, and transmits the location information to the location relay server 170 through the mobile communication network. do.

When the current location information of the outgoing telematics is generated through the above process and the current location information of the incoming telematics is provided, the navigation program determines that the incoming telematics of the outgoing telematics is based on the current location information of the outgoing telematics and the incoming telematics. In operation 330, it is determined whether the wireless communication range exists within the short range wireless communication range.

If the outgoing telematics and the incoming telematics are within the short range wireless communication range (335), the navigation program included in the outgoing telematics determines the short range wireless communication means (= second wireless communication means) as the telematics wireless communication means (340). .

When the short range wireless communication means is determined as the wireless communication means for the outgoing telematics and the incoming telematics as described above, the navigation program provided in the outgoing telematics is connected to the incoming telematics through the short range communication unit 150 in cooperation with the wireless communication multiplexer 105.

If the outgoing telematics and the incoming telematics immediately regain the short range wireless communication range after the communication session error occurs (435), the wireless communication multiplexer 105 provided in the outgoing telematics determines the short range wireless communication means between the outgoing telematics and the incoming telematics (= A short-range wireless communication session using the second wireless communication means is automatically maintained (440).

On the other hand, if the outgoing telematics and the incoming telematics are out of the short range wireless communication range after the communication session error occurs (445), the wireless communication multiplexer 105 provided in the outgoing telematics is a mobile communication network (= first) between the telematics. Wireless communication means) and automatically converts a short-range wireless communication session using short-range wireless communication to a wireless communication session using a mobile communication network (455).
