A base station controller (BSC) 111 that performs call mobility management and the like. The mobile switching manager (MSC) 102 plays a role of transmitting and receiving data and control signals between other communication networks such as a PSTN, an Internet network, or lower networks of base stations of the same operator. In addition, the exchange 102 is connected to a traffic information system and a geographic information system for providing traffic information according to the present invention.

The traffic information system 120 includes a plurality of bus route information and a predetermined program for searching for a corresponding bus route according to a departure point and a destination, and traffic from the terminal through wireless communication with the mobile communication terminal 101. It receives the information request signal and serves to provide traffic information corresponding to the request signal. The geographic information system 130 stores map information on an area via the plurality of bus routes, and the map information is independently stored for each bus route.

On the other hand, the mobile communication terminal is composed of a combination of the terminal control unit 201, data memory unit 204, wireless transceiver 205, location information receiver 203 as shown in FIG.

The terminal control unit 201 forms a predetermined communication connection relationship with all components of the mobile communication terminal to control the overall operation of the mobile communication terminal, and the data memory unit 204 is basically a mobile communication terminal. It stores a program required for the operation of the operation and various data generated by the operation of the mobile communication terminal, and particularly stores the location information received from the satellite 103 and traffic information input from the traffic information system, etc. Do this. The wireless transceiver 205 transmits a signal received through the antenna 206, for example, a traffic information signal received from the traffic information system 120, to the terminal controller 201, or the terminal controller 201. For example, it serves to output a signal generated from, for example, a traffic information request signal to the outside through the antenna 206.

A bus route search program is driven to display a bus route search search screen on the display window of the terminal (S301). The search screen is provided with input fields of a starting point and a destination.

When the user inputs a starting point and a destination on the search screen (S302) and generates a search event (S303), the terminal controller 201 checks the starting point and the destination event and sends the corresponding information to the traffic through the base station and the exchange 102. It transmits to the information system 120 (S304).

When the traffic information system 120 receives an event for the departure point and destination from the terminal, the traffic information system 120 searches for a bus route corresponding to the corresponding departure point and destination. At this time, the search target bus routes are a plurality of bus routes stored in the traffic information system 120. When the search process in the traffic information system 120 is completed and a bus route corresponding to the departure point and the destination is derived, the corresponding bus route search result is transmitted to the terminal (S305). Here, the bus route included in the bus route search result may be at least one or there may be no route matching the search word, that is, the starting point and the destination.

The bus route search result transmitted to the terminal is displayed on the display window of the terminal under the control of the terminal controller 201. If at least one bus route is included in the bus route search result, the user may select a specific bus route. When the user selects a specific bus route (S306), the terminal controller 201 transmits the specific bus route event to the traffic information system 120. The traffic information system 120 interoperates with the geographic information system 130, extracts map information on an area via the corresponding bus line, and transmits the map information to the terminal again (S307). The corresponding map information transmitted to the terminal is displayed on the display window of the terminal.
