Abstract

A method for providing navigation information to a navigation terminal user. The method allows an ITS terminal to receive navigation information from an information center via a mobile communication terminal, and audibly guides the navigation information to a user. The method for a navigation terminal using a wireless network to receive navigation information related to a predetermined position from an information center comprises the steps of: a) transmitting position information to the information center via a voice channel; and b) receiving the navigation information related to the predetermined position from the information center via a data channel.

Claims

1. A method for an ITS (Intelligent Transportation System) terminal to receive navigation information from an information center via a mobile communication terminal, and to provide the navigation information to a user, comprising the steps of:

a) requesting the mobile communication terminal to call the information center, and connecting a voice channel with the information center;

b) receiving a user'"'"'s voice signal indicating a destination, and transmitting the user'"'"'s voice signal to the information center via the voice channel;

c) after transmitting the user'"'"'s voice signal to the information center, requesting the mobile communication terminal to cut off connection of the voice channel, and requesting the mobile communication terminal to connect a data channel with the information center; and

d) receiving navigation information related to the user'"'"'s voice signal from the information center via the data channel.

2. The method as set forth in claim 1, further comprising the step of:

transmitting current position information to the information center via the data channel, prior to receiving the navigation information.

3. A method for an ITS (Intelligent Transportation System) terminal to receive navigation information from an information center via a mobile communication terminal, and to provide the navigation information to a user, comprising the steps of:

a) connecting the mobile communication terminal in a voice communication with the information center;

b) checking caller information in the information center, and transmitting a voice message requesting destination information transmission;

c) outputting the voice message received via the mobile communication terminal to a speaker from the ITS terminal, and enabling a user to audibly recognize the voice message;

d) if the user inputs a voice signal indicating a destination, transmitting the voice signal to the mobile communication terminal from the ITS terminal, and transmitting the voice signal to the information center via the mobile communication terminal;

e) recognizing the voice signal indicating the destination in the information center, searching a database in the information center, transmitting a voice message indicating recognition completion of the voice signal to the mobile communication terminal, and then cutting off the voice communication connection;

f) if the mobile communication terminal receives the voice message indicating recognition completion of the voice signal, attempting to perform a data communication connection, and transmitting current position information to the ITS terminal;

g) if the ITS terminal receives the current position information, calculating in the information center a path from a current position to a destination in order to form path data, and cutting off the data communication connection; and

h) receiving the path data via the mobile communication terminal in the ITS terminal, and audibly generating the path data.

4. The method as set forth in claim 3, wherein the step (a) includes the step of:

if a user presses a voice input button of the ITS terminal, requesting in the ITS terminal a navigation mode operation from the mobile communication terminal.

5. The method as set forth in claim 3, wherein the step (a) is performed when a user selects a voice input menu of the mobile communication terminal.

6. A method for a navigation terminal using a wireless network to receive navigation information related to a predetermined position from an information center, comprising the steps of:

a) transmitting position information to the information center via a voice channel; and

b) receiving the navigation information related to the predetermined position from the information center via a data channel.

7. A method for a navigation terminal using a wireless network to receive navigation information related to a predetermined position from an information center, comprising the steps of:

a) connecting a voice channel with the information center;

b) if the information center requests position information, receiving a request signal of the information center, and generating the request signal to allow a user to recognize it;

c) if the user audibly inputs the position information, transmitting the audibly-input position information to the information center; and

d) after the information center recognizes the position information, cutting off the voice channel connection, establishing a data channel connection to transmit navigation information related to the position information via the data channel, and cutting off the data channel connection upon receiving the navigation information.
