The present invention relates to a mobile communication terminal. In particular, the present invention relates to a location of a mobile communication terminal and a simple image traffic information service. An apparatus and method for linking an image traffic information service to a current location are provided.

In general, a mobile communication terminal is a device that allows a user to receive a mobile communication service using a mobile communication system.

1 is a conceptual diagram for a method for providing public transportation information according to a location in a conventional mobile communication terminal.

Here, reference numeral 10 is a mobile communication terminal, 20 is a mobile communication company server, 30 is a location information server, 41 is a public transportation information DB (Database, database), 42 is a map DB.

The mobile communication terminal 10 calculates the current position value in advance by using a GPS or three base stations and stores it in the memory.

This may be used to register the location value in the terminal at a predetermined time interval by the GPS system or the like, or may calculate and store the location value at the time of requesting the public transportation information service.

In addition, the mobile network connected to the mobile communication terminal 10 mainly consists of a cell-based base station and an exchange station, and the mobile communication company server 20 may be a concept including an exchange station.

The location information server 30 includes a public transportation information DB 41 and a map DB 42, and receives the destination, the type of transportation to be used and the current location from the mobile communication terminal 10, or two DBs 41 and 42. ) Is transmitted to the mobile communication terminal 10 again.

If the type of transportation to be used among the information received from the mobile communication terminal 10 is set to subway, the subway station nearest to the current location and the destination is searched from the public transportation information DB 41, and the current location is converted into a coordinate value on the map. By converting, a map image of a predetermined area including a current location and a nearby subway station is extracted from the map DB 42.

The map stored in the map DB 42 may be statically maintained to the extent that it can be properly represented on the terminal LCD screen, and the map area included may vary depending on the distance between the current location and the subway station. It can also be accumulated and converted to suit the screen of the terminal.

FIG. 2 is a detailed block diagram of the mobile communication terminal in FIG. 1.

The control unit 11 is mainly provided with a function for calculating the current position from the data demodulated by the GPS (Global Positioning System) receiving unit 19. In addition, if the terminal calculates the location using the base station, the GPS receiver 19 is not required separately. In this case, the control unit 11 requests the base station to transmit the location data, receives the location data from the base station, and receives the location therefrom. You must have the ability to extract values.

The memory unit 14 provides a temporary storage place for transmitting the destination and the type of transportation to be used, and a place for storing public transportation information received from the location information server later, and the display unit 12 is controlled by the controller 11. It outputs an interface that allows you to input the destination and the type of transportation to be used on the LCD and the contents of the received public transportation information.

In addition, the mobile communication terminal 10 includes a key input unit 13 for inputting a key value, a transceiver 15 for transmitting and receiving data, a frequency synthesizer 16 for synthesizing frequencies, and a voice processing unit for performing voice processing. (17), a duplexer 18 for performing duplexing of a signal, and the like. These means are well known in the art, and their functions will be apparent to those skilled in the art, and thus detailed operation descriptions are omitted.

A terminal having such a structure to realize a conventional function includes a cordless phone, a cellular phone, a personal communication system (PCS) phone, a mobile phone such as an International Mobile Telecommunication in the year 2000 (IMT2000), and a personal digital assistant (PDA). , A personal computer (PC), a laptop PC (lap-top PC), a palmtop PC (HPC) such as a palm-top PC (Handheld PC), GPS terminal and the like.

3 is a flowchart illustrating a method for providing public transportation information according to a location in a conventional mobile communication terminal.

The mobile communication terminal 10 calculates and stores its current position using a GPS system or three base station systems (ST1). Alternatively, the location calculation may be performed at the moment of selecting a menu such as 'request for public transportation information' in the terminal to request the public transportation information to the mobile communication company server 20 (ST2).

When the above menu is selected, the destination and the type of transportation to be used are sequentially entered (ST2), and the public carrier information is requested to the mobile communication company server 20. At this time, the location information server 30 connected to the mobile communication company server 20 is internally selected. Information and the calculated current position value are transmitted (ST3).

The location information server 30 searches for the transit information DB 41 and the map DB 42 by using the information received from the mobile communication terminal 10 and, as a result, constructs the transit information to be transmitted to the user ( ST4). At this time, the public transportation information is composed of a map image showing a current location and a station close to it, a name of a nearby station, a station name of a destination, and an estimated time between two stations.

If the station is a search result bus, but there is no vehicle to reach its destination, or if a nearby station is located outside a predetermined distance, an error message is sent instead of public transportation information. The user terminal 10 receives the public transportation information or an error message and outputs the contents on the screen (ST5).

First, the location information download unit 52 downloads the location information using the node in the mobile communication terminal 50. At this time, the location information may be configured as shown in FIG. That is, a mobile communication terminal 50 such as a mobile phone is basically difficult to embed an electronic map, and currently provided simple image traffic information does not include GPS information and requires a new standard. Thus, when the traffic information format is modified to the same format as in FIG. 6, the current location of the mobile communication terminal 50 can be displayed.

Such a format may be index information, node information, location information, traffic condition value information, and the like. The location information may be a GPS location value or a location value by a base station. Can be set.
