The present invention relates to a communication terminal, and more particularly, to a traffic information providing method of a communication terminal for providing traffic information and detailed surrounding information.

Due to the heavy rains of the last rainy season, the Yeongdong Expressway was blocked by landslides, and the national road was lost and could not be operated. Several drivers managed to avoid danger due to sudden landslides and road loss.

If you inform the driver of such sudden road accidents in advance, you might have thought a lot about how convenient it would be to have a car navigation system to help you quickly identify a road accident or traffic jam.

However, the conventional navigation system only grasps and guides a route to a current location and a destination, and does not provide road traffic information. The road traffic information mentioned above refers to traffic jams or traffic accidents along the route. Therefore, the user had to monitor the terminal periodically to obtain the desired information when moving to the destination, and had to use the other terminal to acquire the other information, and thus suffered a double inconvenience.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object thereof is to provide a communication terminal that displays traffic information and detailed information of the surroundings by using a TPEG service.

Communication terminal according to the present invention for achieving the above object and a receiving unit for receiving location information; A memory for storing a traffic information map; A controller configured to search for traffic information corresponding to the location based on the location information, download detailed neighborhood information associated with the traffic information, and map the detailed neighborhood information to the traffic information; And a display unit for displaying the traffic information and the detailed surrounding information under control of the controller.

In addition, the traffic information providing method of the communication terminal according to the present invention comprises the steps of: the communication terminal to determine the current location, the traffic information corresponding to the identified location; Displaying the retrieved traffic information; If there is a key input of the user requesting detailed surrounding information, the method includes the step of downloading the traffic information corresponding to the identified location and the detailed surrounding information from the network and mapping the detailed surrounding information to the traffic information to display the mapping. .

Prior to explaining the configuration of the present invention, the TPEG (Transport Protocol Experts Group) service is briefly described as a technology for implementing traffic information data in a terminal through a digital multimedia broadcasting (DMB) broadcast signal. Unlike conventional navigation, which simply serves as a road guide, it displays real-time traffic information without a separate device.

In order to receive the TPEG service, a navigation device for a combined DMB reception is required, and when the terminal is used, a road blockage is automatically displayed on the navigation map, and the shortest course to the final destination is avoided. In addition, it is possible to find out the traffic conditions and the speed of the road to be driven ahead of time, as well as road construction and accident news, as well as information on danger zones and camera control points in advance. Along with this, you can also check out various information such as restaurants, tourist destinations, accommodations, gas stations, etc., as well as daily information such as news, weather, and nearby parking lots.

In addition, it is possible to receive real-time services such as fast road search, vehicle speed display on the road to be driven, optimal detour road guidance. It is especially convenient in that it provides travel information of the destination and danger and rescue information of the accident area.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The display unit 140 receives and displays display data corresponding to a key signal from the key input unit 110 according to a control signal of the controller 150, and displays an operation state of the mobile communication terminal and a plurality of information. And characters.

Preferably, the traffic information and the detailed surrounding information are displayed according to the control signal of the controller 150.

The controller 150 searches for traffic information corresponding to the location based on the location information, downloads detailed surrounding information associated with the traffic information, and maps the detailed surrounding information to the traffic information.

The detailed surrounding information is received using a Transport Protocol Experts Group (TPEG) service. In addition, the traffic information and the detailed surrounding information is a map provided from a broadcasting network or a communication network or embedded in the communication terminal, and after searching the current location through the receiver 100, searches whether a map corresponding to the current location exists. . That is, it is searched whether a map corresponding to the location exists in the corresponding communication terminal. As a result of the search, if there is a map according to the current location, detailed surrounding information associated with the current location is extracted using the TPEG service.

If the traffic information and the detailed surrounding information cannot be obtained through the broadcasting network, the controller 150 obtains the information through the communication network.

That is, when the acquisition of the information fails through the broadcasting network, the service delay is minimized by acquiring the information through the communication network.

In addition, the controller 150 outputs the information received through the receiver 100 through the sound output unit 130 using a text-to-speech (TTS) function.

That is, the traffic information and the detailed surrounding information message is output as a voice.

Preferably, the TTS voice is at least one of a female voice, a male voice, and a baby voice.

2 is a flowchart illustrating a traffic information providing method of a communication terminal according to the present invention.

The communication terminal determines the current location (S200), and searches for traffic information corresponding to the identified location (S210). That is, it is searched whether there is a map according to the current location in the communication terminal, and the road traffic information associated with the current location is extracted using the TPEG service according to the search result.

Then, the searched traffic information is displayed (S220).

If there is a detailed surrounding information request input by the user (S230), the traffic information and the detailed surrounding information corresponding to the identified position are received from the network (S240). Preferably, the detailed surrounding information is included in a Transport Protocol Experts Group (TPEG) message, and the detailed surrounding information includes a traffic accident, a road danger section, a camera location, a bypass road, and a nearby restaurant information.

More preferably, if a place of interest such as an entertainment area, a public institution, a lodging establishment, etc. is registered in advance in the detailed surrounding information, it is displayed on the display unit 140 together with traffic information.

In addition, when the traffic terminal and the detailed surrounding information is received from the network when the communication terminal is in the IDLE state, the user is notified by using a pop-up notification function. Outputs specific sound through the speaker or informs you via the LCD lamp of the communication terminal. If the traffic information and the detailed surrounding information cannot be acquired through the broadcasting network for accurate information, the service delay is minimized by acquiring through the communication network. Thereafter, the detailed surrounding information is mapped and displayed on the traffic information (S250).

That is, the detailed surrounding information is synthesized and displayed on the road traffic information map.

On the other hand, if there is no detailed surrounding information request input in S230, only traffic information is displayed (S220).

Preferably, the method for providing traffic information according to the present invention checks whether the stored traffic information map is updated to the user, and if the user wants to update the traffic information map, the traffic information map is updated.

More preferably, the traffic information providing method according to the present invention, when the user is requested to update the detailed surrounding information of a specific area, the detailed surrounding information summary for the specific area is requested using a bidirectional channel.

Thus, by synthesizing and displaying the surrounding degree summary map on the traffic information map, more detailed traffic information is provided to the user. In this case, the traffic accident information and the surrounding restaurants may also be displayed, and information to be bypassed may also be provided.
