By providing a tracking service, each service will be described with reference to the flow chart of FIGS.

First, FIG. 3 is a flowchart illustrating an information providing service from a system to a vehicle. In operation S10, the entire system of the information center 100 is turned on in a standby state in order to provide various types of information. In this case, the step of receiving location information from the plurality of GPS satellites 11 and accessing the wireless communication network 12 is performed.

In step S11, the driver of the vehicle 10 requests the desired information through the terminal 90, which is a communication type vehicle navigation apparatus installed in the vehicle 10, so as to request information about traffic information, POI, or optimal route. do.

The point of interest (POI) is a data format that allows various location information to be exchanged through the Internet, and provides location data in various applications such as a conventional navigation system (CNS), a digital map, and a personal digital assistant (PDA). Although it was not possible to exchange them, POI combines PHS with car navigation to provide a standard platform for exchanging location data between different applications or products of different companies through a network. In addition, POI can search various homepages using XML as a text and image data description language on the network. It also uses the same format, whether the object is stationary or moving, and its simple format makes it easy to handle in limited-function systems such as PDAs and car navigation systems. Since the POI can link various additional information to the location information, for example, it is possible to link information such as a business hours, a price range, a specialty dish, etc. while explaining the location of a restaurant.

In step S12, it is determined whether a connection is made to a wireless communication network using a wireless data communication function (IWF), which is a network interlocking device of the terminal, and if a connection is made to the wireless communication network 12, transmitting a protocol for connection. (S13).

In addition, in step S14, the terminal 90 receives various types of information from the corresponding server of the information center 100 as data, and when the reception of the data is completed, the terminal 90 of the terminal 90 in step S15. The wireless data communication function (IWF) ends.

Furthermore, in step S16, the received data is displayed through the display unit 93 of the terminal 90, and the data received in step S17 is included in the terminal 90 so as to be interlocked and displayed by various software. do. At this time, the interworking functions include route guidance or POI location view.

In addition, when the wireless communication network 12 is not connected to the wireless data communication function IWF of the terminal 90 in step S12, the connection of the network interlocking device to the wireless data communication function is performed in step S18. Will retry. At this time, it is determined whether the connection by the network interlocking device of the terminal 90 is made, and if the connection is not made, the step of attempting to connect the set number of times is performed (S19). The set number of times is limited to the number of times set in the number of times of access attempted in step S18, for example, within three times.

Therefore, when the connection is not made for the number of times set in step S20, the guide voice stored in the system is output to notify the driver of the connection problem, so that the problem of the connection state can be easily recognized.

Next, Figure 4 is to provide a safety service from the system to the vehicle, in step S30 by pressing the safety service button of the input unit 92 configured in the terminal 90 mounted on the vehicle 10 ( On, it is determined in step S31 whether to transmit the current position information of the vehicle 10 and the driver's information data to the safety center via the wireless communication network 12 to the short message SMS. At this time, the transmitted information data includes GPS information and a telephone number.

When the short message is transmitted in step S32, the user waits for a call with the safety center 200, and in step S33, a voice connection with a guide of the safety center 200 is made. While waiting for the voice connection, a call tone is received from the safety center 200. When the voice connection is made, a voice call is performed between the driver and the guide of the vehicle 10 in step S34.

On the other hand, if the short message is not transmitted in step S31, the connection with the safety center 200 is retried in step S35, and when the connection to the safety center 200 is not made. In step S36, an attempt is made to access the number of times set for the transmission of the short message. The set number of times is limited to the number of times set in the number of times of attempted connection in step S35, for example, within 5 times.

Next, FIG. 5 provides a vehicle location tracking service from the system to the vehicle. In step S40, the driver or the customer of the vehicle passes through the mobile communication terminal or the public telephone network 80 to the safety center 200. Report the theft of the, at this time the report is to report the customer's information with the customer for authentication. Therefore, in step S42, the customer performs verification and authentication processing with respect to information such as registration and setting matters for the reported customer, for authentication to the safety center 200.

If the authentication process is performed for the customer in step S43, the client's message is transmitted to the safety center 200. In step S44, it is determined whether the data transmitted by the customer is received in the safety center 200. Done.

In step S45, after monitoring the data information received from the customer in the safety center 200, the corresponding action, for example, by tracking the location of the vehicle or the registered status of the stolen vehicle registered in the government office or the like through step S46 or Inquiries will be made regarding the status of notification of unidentified vehicles.
