BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal and a method for notifying location information by voice. In particular, the present invention provides voice information on the current location information of a user using geographic information provided by a global positioning system (GPS). The present invention relates to a mobile communication terminal and a method.

In general, the Global Positioning System (GPS) is a global radio navigation satellite system developed and promoted by the Department of Defense (DOD) and uses a navigation system with Time And Ranging (NAVSTAR), which is a medium- and high-orbit navigation satellite system. Also known as NAVSTAR / GPS. The system consists of a total of 24 avionics, ground control stations managing satellites, and user's mobile stations, each of which was fired four at six circular orbits with an altitude of about 20,000 km, a period of about 12 hours, and an orbital inclination of 55 degrees. Each satellite is equipped with an atomic clock.

Since such a location information system is arranged so that at least four satellites are always in the field of view anywhere in the earth, the user selects an appropriate four of these satellites and receives visual signals from them to measure each distance. Since the positions of the four satellites are known, this measurement shows the user's three-dimensional position of latitude, longitude, and altitude and the visual deviation of the field of view. The transmission frequency from the satellite is two waves of 1,575.42 MHz and 1,227.6 MHz, and these two waves compensate for ionospheric delay. The navigation signal includes a navigation information of 50bps and is a phase shift modulated (PSK) signal spread spectrum modulated with a pseudo noise code (PN code). There are two kinds of pseudo-noise codes: P code (precision code) and C / A code (clear and acquisition code). The P code is 10.23Mbps for the purpose of precision positioning with one week period. The C / A code is 1.023 Mbps and the period is about 1 millisecond (ms). These pseudo-noise codes can be used to decode the navigation signal or to measure the distance between the satellite and the receiving station. The 1,575.42 MHz contains the P code and the C / A code, and the 1,227.6 MHz contains only the P code. Currently, the C / A code has a code pattern for private use, but the P code is secret. It is known that the position measurement accuracy by C / A code is within 100m of nominal, and the precision by P code is within 16m of nominal. It was originally built for the positioning of military vehicles, ships and aircraft. Nowadays, it can be used by civilians, so it is used for navigation devices installed in automobiles, navigation devices such as ships and helicopters.

It is also used for remote operation of unmanned construction and earthquake measurement systems for earthquake forecasts. Recently, the navigation system combined with geographic information contained in a read-only compact disc storage device (CD-ROM) can provide relatively low cost, and the market is rapidly expanding.

The GPS is mainly used in a car navigation system, but recently, it is also applied to a mobile communication terminal.

Referring to a process of providing a user with location information provided by a GPS in a conventional mobile communication terminal, first, a mobile communication terminal receives current location information from a satellite and transmits the location information to a base station. The base station analyzes the received location information, calculates the location of the mobile communication terminal, and transmits the calculated location information to the mobile communication terminal. At this time, the mobile communication terminal displays the location information received from the base station on the map to show the user.

As such, since the conventional mobile communication terminal displays the location information on the map, the user can check his / her location only after deciding a certain time, and the user who is driving can easily check the current location displayed on the map. Could not be confirmed.

The microphone 240 and the position information received through the GPS receiver 230 are transmitted to the base station 300 according to a user's instruction input through the keypad 210, and the position coordinate information received from the base station 300. And stores the voice location information input through the microphone 240 in the memory 220, outputs the location information stored in the memory 220 as voice, and controls the provision of a call service and various additional services. The control unit 250, the liquid crystal display (LCD) 260 for displaying the position information and various additional information transmitted by the control unit 250, and the baseband signal transmitted by the control unit 250 is a high frequency signal Converts the radio frequency signal to the outside and converts the high frequency signal received through the base station into a baseband signal and connects it to the control unit 250, and the position information transmitted by the control unit 250 is voiced. A speaker 280 for outputting is provided.

On the keypad 210, keys for inputting numbers, symbols, characters, and the like, and keys for selecting various menus and executing various functions are arranged. When the keypad is pressed by the user, the keypad 210 generates a key signal indicating an input of numbers, symbols, characters, etc. or a key signal indicating the execution of a call and various additional services, and transmits the generated key signal to the controller 250. . That is, the user may input a user command for providing location information by using a key on the keypad 210.

However, for the convenience of the user, a location information key for inputting a user command for providing location information may be separately implemented. In this case, the location information key may be disposed to be spaced apart from the keypad 210.
