The method of the present invention using the apparatus according to the present invention configured as described above comprises: a destination input step of receiving a destination from a user according to a user's selection of a geographic information providing function in a mobile communication terminal to which Bluetooth wireless communication is additionally used; A geographical information request signal transmitting step of transmitting a geographical information request signal including the input destination to a geographical information inquiry apparatus through a Bluetooth wireless communication; A geospatial data retrieval step of retrieving geospatial data retrieved through a database according to a geospatial request signal transmitted from the geographic information retrieval apparatus; And transmitting the retrieved geospatial data to the mobile communication terminal through Bluetooth wireless communication, and outputting the geospatial data from the mobile communication terminal to a speaker or a liquid crystal display.

Referring to FIG. 3, the present invention made as described above is described in detail. A geographic information inquiry apparatus 100 storing geographic information data about a surrounding area is installed at a predetermined place such as a crosswalk or an intersection. The mobile communication terminal user who enters the pedestrian crossing or the intersection around the inquiry apparatus 100 is provided with geographic information on the destination by using the second Bluetooth 207 installed in the mobile communication terminal.

For example, when a visually impaired person who uses the mobile communication terminal 200 enters an intersection or a crosswalk and wants to obtain information about a destination to which he / she wants to move, the terminal user is provided in the key input unit 203 of the terminal. The selected button selects a function button related to the geographic information providing function or a user interface menu (S1).

According to a user's selection of a geographic information providing function, the control unit 201 of the mobile communication terminal 200 transmits a Bluetooth for geographic information service to the first Bluetooth 101 of the geographic information inquiry apparatus 100 through the second Bluetooth 207. Performs a connection setting (Blue-tooth Connection) (S2).

The controller of the mobile communication terminal determines whether the Bluetooth connection has been completed through the Bluetooth connection setting completion signal transmitted from the second Bluetooth (S3).

If it is determined that the Bluetooth connection with the second Bluetooth is not established, the user is notified of the connection setup failure and the user is inputted whether or not to try again. If the attempt is selected, the process returns to the Bluetooth connection setting routine. If the retry is not selected, an error message indicating the connection failure is displayed on the liquid crystal display 204 of the terminal and the process ends (S5).

As a result of the determination, when the Bluetooth connection with the first Bluetooth 101 is established in the second Bluetooth 207, a destination for receiving geographical information is received from the user (S6).

The controller 201 of the mobile communication terminal 200 converts data about a destination input from the user into a Bluetooth data transmission packet through the second Bluetooth 207 and transmits the data to the first Bluetooth 101.

The first Bluetooth 101 transmits a reception completion response signal for the received data packet. Through the reception completion response signal, the control unit 201 of the terminal 200 determines whether data for the destination is transmitted to the geographic information providing device. It is determined whether or not (S7).

As a result of the determination, if the reception completion response signal transmitted from the geographic information providing apparatus is not received, the controller of the terminal requests re-entry to the user (S8). Switch to the receive standby mode for receiving geospatial data for the destination.

Through the above process, the microprocessor unit 102 in the geographic information inquiry apparatus 100 that receives the destination data received from the mobile communication terminal 200 searches for the corresponding geographic information data through the database 103 ( S9) It is determined whether the data for the destination desired by the user exists according to whether the geographic data matched with the search result is detected (S10).

When the geospatial data matched with the determination result is found, the microprocessor unit 102 in the geospatial information inquiry apparatus 100 transmits the corresponding geospatial data to the second Bluetooth 207 requesting the geospatial data through the first Bluetooth 101 ( S11) If no matching geospatial data is found, an error message indicating that there is no geospatial data for the requested destination is transmitted to the second Bluetooth 207 (S12).

The control unit 201 of the mobile communication terminal 200 which has received the geospatial data transmitted through the above process outputs the received data through the speaker 208 so that the visually impaired who is a terminal user can use a means of transportation for moving to a destination. Information such as distance and direction can be obtained.

For example, if a mobile communication terminal user wants to move to 'Chungmuro', the terminal user wants to check the bus passing through the destination at the bus stop in the process of moving to the destination. Select the information provision function or the corresponding function button.

According to a user's selection of a geographic information providing function, the control unit 201 of the terminal 200 uses the first Bluetooth 101 in the geographic information inquiry apparatus 100 installed at a bus stop via a second Bluetooth 207 which is a mounted Bluetooth module. And establish a Bluetooth communication link for geographic information service.

When the Bluetooth communication link with the first Bluetooth 101 is established, the control unit 201 of the terminal 200 receives the destination data received from the user through the second Bluetooth 207 or registered in the geographic information providing function. To send).

The microprocessor unit 102 of the geographic information inquiry apparatus 100 searches for geographic information data corresponding to a destination received through the first Bluetooth 101 through the database 103 and moves when the corresponding data is found. Transmit to communication terminal 200.

Through this process, the user transmits information on the means of transportation to the searched destination 'Chungmuro' to the mobile communication terminal 200 and is provided to the user through the speaker 208 or the liquid crystal display 204 of the terminal. will be.

As described above, according to the present invention, by receiving the geographic information data from the geographic information inquiry device to the destination through the Bluetooth module equipped with the mobile communication terminal user, even in the case of normal people as well as visually impaired traffic Since the use of a means or a wrong direction can be reduced to find a destination, a mobile terminal user can more conveniently move to a desired destination.
