TECHNICAL FIELD
The present invention relates to a traffic condition data providing method using a wireless communication device and a navigation device performing the method, and more specifically to a method and device that may receive traffic condition data from a content managing server through a wireless communication device to allow a user to identify a traffic condition over a travelling path in a real-time animated manner.
BACKGROUND ART
A driver wants to previously know traffic information on a travelling path to arrive at their destination more quickly. In particular, if the destination may be reached through a bypass known based on traffic information acquired in real time in a case where an accident occurs, it is efficient in terms of driving time.
A navigation device may obtain traffic information in real time through TPEG protocol. However, in the case of receiving real-time traffic information through TPEG, it fails to reflect traffic conditions varying fast. Further, real-time traffic information using TPEG differentiates a traffic condition from another, and thus, it is difficult for a driver to identify actual traffic conditions in a specific position.
Therefore, there is a need for a method that may acquire animated information reflecting real-time traffic information through a navigation device while a driver drives, thus providing the driver with convenience.

The wireless communication terminal 103 and the wireless Internet access device 106 are not limited to specific types.
Resultantly, the navigation device 104 or 105 may receive the traffic condition data from the content managing server 101 through the wireless communication terminal 103 or the wireless Internet access device 106.
FIG. 2 is a block diagram illustrating an entire construction of a navigation device according to an embodiment of the present invention.
Referring to FIG. 2, a navigation device 200 may include a travelling path displaying unit 201, a traffic condition data receiving unit 202, and a traffic condition data providing unit 203.
The travelling path displaying unit 201 may search a travelling path to a destination set by a user and may display the travelling path on map data. In this case, the user may select a position for receiving the traffic condition data on the travelling path.
The traffic condition data receiving unit 202 may receive the traffic condition data from the content managing server through the wireless communication device in response to a providing request of the traffic condition data on the travelling path. As an example, the traffic condition data may be at least one of traffic information data, CCTV data, or variable message sign data on the traveling path. The traffic information data may be provided in the form of text, and the CCTV data and the variable message sign data may be provided in the form of an image.
At this time, the wireless communication device may be a wireless Internet access device provided in the navigation device 200 or a wireless communication terminal that may perform near field communication with the navigation device 200. For example, in the case that the wireless communication device is a wireless Internet access device, the traffic condition data may be directly received from the content managing server attached to the navigation device 200. And, in the case that the wireless communication device is a wireless communication terminal, the wireless communication terminal may receive the traffic condition data from the content managing server and may transmit the received traffic condition data to the navigation device 200 through near field wireless connection.
At this time, the navigation device 200 may search a wireless communication terminal that may perform near field wireless communication and is located near in response to a traffic condition data providing request from the user. For example, if the user makes the traffic condition data providing request through a display of the navigation device 200, the navigation device 200 may search a wireless communication terminal located near. As an example, the wireless communication terminal may include a terminal, such as a cellular phone or a PDA that supports a WPAN (Wireless Personal Area Network).
At this time, the wireless communication terminal may be a terminal that may perform near field wireless communication with the navigation device 200. For example, the near field wireless communication may include a wireless communication scheme, such as an infrared scheme, a RF (Radio Frequency) scheme, a Bluetooth scheme, a ZigBee scheme, or a UWB (Ultra Wide Band) scheme.
At this time, the navigation device 200 may receive the traffic condition data from a wireless communication terminal identified to subscribe for a service of providing the traffic condition data through terminal authentication with the content managing server. As an example, the terminal authentication of the navigation device 200 may be completed if the navigation device 200 is registered in the content managing server and wireless connection information stored in the navigation device 200 is matched. At this time, whether the navigation device 200 has been registered in the content managing server may be identified using terminal information including at least one of identification data, a terminal model, or a product number of the wireless communication terminal.

As an example, in a case where the wireless communication terminal and the navigation device 200 are wirelessly connected to each other, the wireless connection information may include an MIN and a Bluetooth address of the wireless communication terminal.
As an example, the traffic condition data receiving unit 202 may analyze points of interest (POIs) over the travelling path and may receive traffic condition data corresponding to the POIs. For example, in a case where there are 10 POIs over a travelling path from A to B, the traffic condition data receiving unit 202 may receive traffic condition data corresponding to the 10 POIs (installation positions of CCTVs or positions of main bridges, main ramps/intersections, or variable message signs, etc.) from the content managing server. In this case, the navigation device 200 may provide the user with a list of the POIs and thus may provide traffic condition data of the POIs desired by the user to the user. At this time, the content managing server may process the traffic condition data based on image setup information including file format, transmission rate, resolution, or frame, and then transmit the processed traffic condition data to the navigation device 200.
The traffic condition data providing unit 203 may provide the received traffic condition data to the user. At this time, the traffic condition data providing unit 203 may provide the traffic condition information in association with map data considering the user's position moving along the travelling path. In a case where the user traveled 1⁄2 of a travelling path from X to Y, the navigation device 200 may provide the user with traffic condition data corresponding to the remaining 1⁄2 travelling path.
FIG. 3 is a view illustrating an example of providing CCTV data and variable message sign data over a travelling path according to an embodiment of the present invention. Referring to FIG. 3, a travelling path screen 301, a CCTV image screen 302, and a variable message sign screen 303 are illustrated.
In a case where the user selects X as a starting point and Y as a destination, POIs a, b, and c may be included over a travelling path from X to Y. At this time, the POIs may correspond to installation positions of CCTVs or positions of main bridges, main ramps/intersections, or variable message signs.
In a case where the user requests the CCTV image screen 302, the navigation device 200 may provide CCTV moving pictures for the POIs to the user through the CCTV image screen 302. The method or type of providing the CCTV moving pictures is not limited to that shown in FIG. 3, and may vary depending on the navigation device. For example, in a case where the user travels from X to Y, CCTV moving pictures corresponding to POIs a, b, and c may be sequentially or simultaneously provided.
And, in a case where the user requests the variable message sign screen 303, the navigation device 200 may provide the user with variable message sign moving pictures of the POIs through the variable message sign screen 303. The method or type of providing the variable message sign moving pictures is not limited to that shown in FIG. 3, and may vary depending on the navigation device. For example, in a case where the user travels from X to Y, variable message sign moving pictures corresponding to POIs a, b, and c may be sequentially or simultaneously provided.
Besides, the navigation device 200 may provide the user with the traffic information of the POIs in the form of text. For example, the navigation device 200 may provide the user with accident information, average speed information, traffic control information within the POIs in the form of text.
FIG. 4 is a view illustrating an example of providing a CCTV image on a map representing a travelling path according to an embodiment of the present invention. FIG. 4 illustrates that a user travels along a travelling path over map data.
As an example, the navigation device 200 may provide a user with traffic condition data associated with the map data considering a user's position moving along the travelling path.
At this time, it is assumed that the travelling path includes X and Y as a starting point and a destination, respectively, and POIs a, b, and c are included within the travelling path. Then, the navigation device 200 may provide the user with CCTV images corresponding to POIs a, b, and c in association with the map data. At this time, the CCTV images may be on/off depending on user's authorization. And, the CCTV images may be replaced by variable message sign images. Likewise, the CCTV images may be replaced by text-type traffic information. At this time, the CCTV images or variable message sign images may be images obtained by processing raw images collected by the content managing server to be suitable for the navigation device 200.
When recognizing that there is traffic congestion or traffic control at point c through the CCTV images or variable message sign images, the user may reach the destination through a bypass instead of passing through point c, thus increasing time efficiency.

At this time, the wireless communication device may include a wireless Internet access device provided in the navigation device 200 or a wireless communication terminal that may perform near field wireless communication with the navigation device 200. As an example, the wireless communication terminal means a terminal in which it is identified whether the wireless communication terminal is subscribing for a service of providing the traffic condition data through terminal authentication with the content managing server. At this time, authentication of the wireless communication terminal may be completed when the wireless communication terminal is a terminal registered in the content managing server and matches wireless connection information stored in the navigation device 200.
In step S502, the navigation device 200 may analyze POIs over the travelling path and may receive traffic condition data corresponding to the POIs. At this time, the traffic condition data may be at least one of traffic information data, CCTV data, or variable message sign data over the travelling path.
And, the content managing server may process the traffic condition data depending on image setup information including file format, transmission rate, resolution, or frame.
In step S503, the navigation device 200 may provide the user with the traffic condition data received from the content managing server. At this time, the navigation device 200 may provide the user with the traffic condition data associated with map data considering user's position moving along the travelling path.
