Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

3 is a flowchart for explaining the main operation of the present invention. As shown, in step S301 the service server 101 establishes a session for maintaining a communication connection with the WiBro communication network, and each region from a plurality of CCTV cameras 107 wirelessly connected to the WiBro communication network in step S303 Receive unique code information about traffic image and camera.

The WiBro communication module 203 receives traffic information and unique code information for each CCTV camera 107 received through the base station 109 and then provides the service operation module 201. The service operation module 201 starts the camera position analysis module 211 and analyzes the position of the photographing camera for the currently received traffic information. This analyzes the location information for the currently received traffic information by matching the unique location information and the location where the CCTV camera 107 is installed.

Thereafter, the camera location analysis module 211 provides a location analysis result to the traffic information classification module 213, and the traffic information classification module 213 provides a currently received image based on the location analysis result for each region and zone. The classification information separated by each is transmitted to the service operation module 201. The service operation module 201 registers traffic information currently received in response to the classification information to the image database 103 through the interface module 205.

As such, the traffic information is a traffic image received in real time through the WiBro communication network and is registered and managed for each region and zone. Managed traffic image information is registered with unique information for each region, for example, a unique code or a region name or coordinates. Thereafter, in step S305, the WiBro communication module 203 of the service server 101 receives a service request signal from an arbitrary receiving terminal 111.

The service server 101 provides the management terminal 105 with the telephone number (or PIN number, mobile registration number) of the receiving terminal 111 in response to the currently received service request signal. In step S307, the management terminal 105 performs member authentication for the receiving terminal 111 requesting the service. Membership authentication can be operated as a paid and free, and can be operated as a free service through mobile banner advertising, if necessary. Here, if the receiving terminal requesting the service is not a registered member, a predetermined member registration guide message is provided, and then the feedback is returned to step S303.

The service information selects a type of service together with a service request signal. The service request signal includes terminal information, a repeater capable of recognizing a terminal location, a base station, and the like, and the service information to be received. Types of traffic images include, for example, selection information about moving images, still images, graphics, and the like, and regional selection information for receiving the corresponding traffic images.

Therefore, the service server 101 analyzes the above-described service information as in step S311, and provides the terminal location analysis module 215 with the location information of the terminal in the analysis result. The terminal position analysis module 215 analyzes the position of the current receiving terminal 111 based on the unique information about the repeater or the base station 109 relaying the receiving terminal 111. The analysis result may be provided as coordinate information corresponding to the position of the receiving terminal 111.

In operation S313, the service operation module 201 extracts geographic information previously stored in the image database 103, that is, geographic information within a predetermined radius, for example, 10 km, from the place where the receiving terminal 111 is located, based on the coordinate information. To this end, the service operation module 201 transfers the coordinate information provided from the terminal location analysis module 215 to the geographic information providing module 209, and the geographic information providing module 209 writes to the image database 103. Geographic information corresponding to the coordinate information is extracted from the stored geographic information.

As shown in FIG. 4, it displays the above-mentioned geographic information on the screen of the receiving terminal 111 and displays the current position of the receiving terminal, that is, the current position of the user, through the initial position display. Thus, the user can easily select any location in proximity based on the geographic information. The location display may be displayed along with the current location of the user in directions such as east, west, north and south, and Gangbuk / Gangnam directions. Of course, as described above, the geographical information is provided from the current location of the receiving terminal 111, but it will be obvious that the user can select an arbitrary region by adjusting the scale of the geographical information. In the present invention, the above-described geographic information may be provided as graphic information, or as shown in the second embodiment, geographic information by satellite photography may be provided.

The user selects a location to be recognized based on the geographic information displayed by the receiving terminal 111. This is for receiving traffic information at a selected location. When the screen of the receiving terminal 111 is configured as a watch screen, an arbitrary location may be selected by locating the corresponding location. The service operation module 201 recognizes the information placed on the watch screen, transmits the corresponding location or coordinates to the traffic information providing module 207, and requests to extract traffic information of the corresponding area.

The traffic information providing module 207 extracts the traffic image information corresponding to the selected position from the watch screen among the traffic image information accumulated in real time to the image database 103 in step S315. The extracted traffic image information is provided to the service operation module 201, but the traffic information providing module 207 may process the corresponding traffic image based on the service information provided or selected from the receiving terminal 111. The processed traffic image includes moving images, still images or graphicized information (numeric information, bar graph information, colors corresponding to the traffic volume, etc.).

In step S317, the service operation module 201 provides a traffic image at a location selected by the user by dedicating one side of the screen of the receiving terminal 111. Of course, the installation position of the above-described CCTV camera 107 and the position selected by the user may not be the same, the traffic image is the position selected by the user among the CCTV cameras provided on the same road as the position selected by the user Provides a video taken by the camera in close proximity to the camera. 5 illustrates an embodiment of the present invention for providing a traffic image.

Step S317 is a billing processing process according to the service provision in the present invention. After the service provision is completed from the service server 101, the processing result is provided to the management terminal 105, so that the management terminal 105 is provided. Performs service charging.
