본 발명은 위성 위치 확인 시스템(GPS: Global Positioning System) 기능이 지원되는 이동통신 단말기를 이용하여 GPS 모듈이 장착된 소정 기기의 위치를 찾는 기술에 관한 것으로, 특히 넓은 주차장에 주차된 차량의 위치나 특정 기기의 위치를 파악하는데 적당하도록 한 지피에스를 이용한 이동통신 단말기에서의 위치 추 적방법에 관한 것이다.The present invention relates to a technology for finding a location of a predetermined device equipped with a GPS module by using a mobile communication terminal supporting a Global Positioning System (GPS) function. The present invention relates to a location tracking method in a mobile communication terminal using GPS, which is suitable for identifying a location of a specific device.

종래 이동통신 단말기에서의 위치추적 기술에 있어서는 사용자가 휴대폰에서 GPS 메뉴를 선택한 후 찾고자 하는 목적지를 입력하여 단문메시지서비스(SMS)로 포지션 메일 서버에 전송하면, 그 서버에서는 기 저장되어 있는 데이터를 바탕으로 목적지의 좌표(위도,경도) 데이터를 SMS로 휴대폰에 전송한다. 이에 따라, 상기 휴대폰에서는 수신받은 좌표 데이터를 근거로 목적지와 현재 위치를 계산하여 엘씨디 상에 목적지까지의 거리를 표시해 주게 되어 있었다.In the conventional location tracking technology in a mobile communication terminal, a user selects a GPS menu on a mobile phone, inputs a destination to be searched, and transmits it to a position mail server using a short message service (SMS). By sending the coordinate data (latitude, longitude) of the destination to the mobile phone by SMS. Accordingly, the mobile phone calculates the destination and the current location based on the received coordinate data and displays the distance to the destination on the LCD.

이와 같이 종래의 이동통신 단말기에 있어서는 위치 추적을 위해 SMS를 이용하고 있는데, SMS는 특성상 정보가 수신되면 단말기 화면에 메시지가 수신되었다는 메시지와 음향을 출력하게 된다. 따라서, 새로운 위치정보를 단말기에 전송할 때마다 특정 메시지와 음향신호를 함께 전송해야 한다. 그런데, 이동통신 시스템에서 SMS 이용자가 많을 경우 SMS를 수신받는데 오랜 시간(예: 30 40분)이 소요되는 경우가 종종 발생되어 정상적인 서비스가 불가능하게되는 문제점이 있었다. As described above, in the conventional mobile communication terminal, the SMS is used for the location tracking. When the information is received, the SMS outputs a message and a sound indicating that the message has been received on the screen of the terminal. Therefore, whenever a new location information is transmitted to the terminal, a specific message and an audio signal must be transmitted together. However, when there are many SMS users in a mobile communication system, it takes a long time (for example, 30 40 minutes) to receive an SMS, and thus there is a problem that normal service is impossible.
