The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication terminal for collecting and updating mobile path information using traffic information broadcasting and a method using the same.

In the conventional mobile communication terminal, a broadcast type DMB traffic information broadcast data receiver and a location information confirmation module such as GPS are configured. DMB traffic information broadcasting is a one-way service that repeatedly transmits traffic conditions of the entire area in real time. The DMB traffic information broadcast receiver performs a basic operation in the form of receiving and simply outputting broadcast data. Then, GPS is used to acquire surrounding information based on location information and display it to the user. Such a broadcasting one-way service is a structure that repeatedly broadcasts the entire traffic information irrelevant to the user's request. In order to utilize the information required for the user's entire travel path or the intelligent traffic information service, an additional data service using the wireless network of the mobile terminal and the GPS location search module other than the DMB traffic information broadcasting service should be used. In addition, there is a problem that a user according to the prior art has to wait until the broadcast time to obtain the necessary traffic information. In addition, there is a problem in that a fee is charged for accessing wireless data communication to obtain traffic information data according to a user's movement route.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a mobile communication terminal which outputs continuous location information by collecting and updating only relevant data while receiving DMB traffic broadcasting information by a user inputting information on a movement route. Its purpose is to.

According to an aspect of the present invention, there is provided a mobile communication terminal including: a traffic information detector configured to receive a traffic information broadcast signal and collect decoded location information data and time information data; A controller configured to compare and determine data of the traffic information detector and input movement path data to extract matching data and calculate an optimal path; And a screen display unit for outputting the optimum route as the traffic information broadcast signal.

The present invention also provides a method for displaying movement route information using traffic information broadcasting, comprising: receiving a starting point and a destination of a predetermined movement route; Detecting location information data and time information data from the received broadcast traffic information signal and comparing and updating data corresponding to the location information of the moving route according to time information; And storing the updated information in a path search data table and calculating an optimal path to output a moving path as the broadcast signal.

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

1 is a block diagram showing a mobile communication terminal for receiving and receiving traffic information broadcasting according to the present invention to collect and update the movement route information.

The wireless communication unit receives the traffic broadcast signal and processes it as a demultiplexing and decoding signal. The traffic information detector has a function of collecting traffic location information data and traffic time information data from the decoded data. The movement route input unit is possible by inputting a starting point, a destination, and a waypoint of the movement route using a predetermined keypad of the terminal, or by displaying a position on a touch screen type screen display unit. The controller compares and determines the data of the traffic information detector and the input movement route data to extract matching data and calculate an optimal route. The optimal path is location information on which an operation having a minimum estimated time due to the path movement is performed. At this time, the optimal path calculation uses a Dijkstra shortest path algorithm. The memory stores a route search data table in which data matching the position information of the route is compared and updated according to time information. The screen display unit outputs the calculated optimal route as a traffic information broadcasting signal.

2 is an exemplary view showing the structure of a DMB traffic information broadcast packet TPEG frame according to the present invention.

The traffic information broadcast packet processes the real-time traffic information data using the TPEG (Transport Protocol Expert Group) and stores it in XML format. Location information data (LOCATION ELEMENTS) and time information data (TIME INFORMATION ELEMENTS) are detected from a Road Traffic Message (RTM) of a Transport Protocol Expert Group (TPEG) frame.

3 is a flowchart illustrating a method of collecting and updating movement route information using traffic information broadcasting according to the present invention.

The starting point and destination of the predetermined movement route are input by using a predetermined keypad or by displaying a location on a screen display unit of a touch screen method (S300). The DMB traffic information broadcast signal is received, demultiplexed, and decoded and processed (S301). The traffic broadcast information and the location of the input movement path are detected at the same point (S302). The detected location information is updated in the location path data according to the time information and stored in the path search data table (S303). An optimal path operation is performed from the stored data (S304). At this time, the shortest path algorithm is used to classify and detect the case of using public transportation and the time of driving. The traffic information of the movement route by the updated latest data is output and displayed as a broadcast signal (S305).

The present invention reduces cost and technology for obtaining location information by extracting and providing the latest data on the moving path required during receiving DMB traffic information broadcasting by inputting the moving path data of the user without additional data transmission and reception using a separate device or a wireless network. This has the effect of simplifying the implementation.
