Abstract

The present invention discloses a method for providing real-time traffic information using a mobile communication terminal through wireless internet, comprising the steps of receiving a request for image by a WAP server when a user requests traffic information image via a mobile communication terminal; analyzing the specification of the mobile communication terminal by the server that has recieved the request; analyzing the type of the image requested by the user and traffic of the requested section by the server; receiving an image that the user has requested by the server; producing an image optimized for the user'"'"'s mobile communication terminal based on the image received by the server; and tramsitting the optimized image to the wireless mobile communication terminal(of the user) using a WAP protocol by the server.

Claims

1. A method for providing real-time traffic information using a mobile communication terminal through wireless internet, comprising:

the first step of receiving a request for image by a WAP server when a user requests traffic information image via a mobile communication terminal;

the second step of analyzing the specification of the mobile communication terminal by the server that has received the request;

the third step of analyzing the type of the image requested by the user and the traffic of the requested section by the server;

the fourth step of receiving an image that the user has requested by the server;

the fifth step of producing an image optimized for the user'"'"'s mobile communication terminal based on the image received by the server; and

the sixth step of transmitting the image as optimized using a WAP protocol by the server to the wireless mobile communication terminal.

2. The method for providing real-time traffic information using a mobile communication terminal through wireless internet as set forth in claim 1, wherein the specification of said mobile communication terminal in said second step comprises the size of LCD screen of the mobile communication terminal, carrier type, and model no. of the phone.

3. The method for providing real-time traffic information using a mobile communication terminal through wireless internet as set forth in claim 1, wherein said fifth step further comprises the steps of:

5-1, wherein the size of the image file received at said fourth step is readjusted to the screen size of the mobile communication terminal;

5-2, wherein the brightness of said image as readjusted in size is analyzed and readjusted to yield an appropriate brightness;

5-3, wherein the edge lines of said image are made sharper utilizing sharpening technique and edge detection technique; and

5-4, wherein a soft image suitable for a mobile communication terminal is produced from said image using the dithering technique.

4. The method for providing real-time traffic information using a mobile communication terminal through wireless internet as set forth in claim 3, wherein each of said fourth and said sixth step comprises an additional step of 4-1 and 6-1 respectively, when the user requests for motion image:

4-1, wherein the next image is transmitted anew when a predetermined time has elapsed; and

6-1, said next images are sent continuously in consideration of the transfer speed on the wireless internet.

5. The method for providing real-time traffic information using a mobile communication terminal through wireless internet as set forth in claim 4, wherein the continuous sending of the images in said step of 6-1 is performed using the timer function of WML so as to coincide with the present transfer speed on the wireless internet.

6. The method for providing real-time traffic information using a mobile communication terminal through wireless internet as set forth in claim 1, wherein said first step further comprises the steps of:

1-1, wherein a custom made traffic information on the roads neighboring to the current location of the user is provided, by automatically recognizing the present location of the user; and

1-2, wherein the relevant traffic information is received if the user selects specific region among said traffic information.

7. The method for providing real-time traffic information using a mobile communication terminal through wireless internet as set forth in claim 1, wherein said first step further comprises the steps of:

1-3, wherein a screen for selection of the administrator menu is provided to the user;

1-4, wherein a further screen for selection of the camera to be controlled is provided to the user, if the user selects the administrator menu; and

1-5, wherein a further screen for change/control of the camera in four directions, i.e. up, down, left, and right, is provided to the user, if the user selects a specific camera.
