본 발명에 의한 지피에스를 이용한 휴대폰의 미아 추적 방법은, 기준 단말기에서 기지국으로부터 자신의 위치정보를 전송받아 업데이트하고, 어린이용 단말기의 위치정보를 전송받아 체크하는 제1과정과; 어린이용 단말기에서 자신의 위치정보를 기지국으로부터 전송받아 업데이트하고, 이 위치 정보를 자신의 ID로 구별하여 상기 기준 단말기에 주기적으로 전송하도록 요구하는 제2과정과; 상기 기지국에 상기 어린이용 단말기의 위치정보가 없는 것으로 판명되면, 기준단말기에서 알람을 출력한 후 그 어린이용 단말기와 자동 통화 연결을 시도하는 제3과정과; 상기 위치정보가 존재하면, 상기 기준 단말기가 자신의 위치정보와 어린이 단말기의 위치정보를 근거로 그들간의 거리를 산출하여 엘씨디에 표시하는 제4과정과; 상기 기준 단말기와 어린이용 단말기와의 거리를 기 설정된 기준거리와 비교하여 그 비교 결과에 따라 경고음을 출력하고 어린이용 단말기로 자동 다이얼링하거나, 위치정보를 업데이트하여 엘씨디에 표시하는 제5과정으로 이루어지는 것으로, 이와 같은 본 발명의 미아 추적 방법을 첨부한 도 1을 참조하여 상세히 설명하면 다음과 같다.MIA tracking method of a mobile phone using GPS according to the present invention includes a first step of receiving and updating its location information from the base station in the reference terminal, and receiving and checking the location information of the child terminal; A second step of receiving and updating the location information of the child terminal from the base station and transmitting the location information to the reference terminal by distinguishing the location information from the base station; If it is determined that the base station does not have the location information of the child terminal, a third step of outputting an alarm at the reference terminal and attempting an automatic call connection with the child terminal; A fourth step of, if the location information exists, the reference terminal calculating a distance between them based on their location information and the location information of the child terminal and displaying the distance on the LCD; Comprising a fifth process of comparing the distance between the reference terminal and the children's terminal with the preset reference distance and outputs a warning sound and automatically dials the children's terminal or updates the location information and displays it on the LCD according to the comparison result. When described in detail with reference to Figure 1 attached to the tracking method of the present invention as described above.

본 발명에서는 3G 데이터 통신이 가능한 CDMA 망과 PDE 장비, GPS-One 기능을 구비한 단말기, 자신의 단말기 위치(위도, 경도, 높이)와 타인의 단말기 위치를 알고 있을 때 이를 계산할 수 있는 간단한 UI 프로그램을 필요로 한다.In the present invention, CDMA network and PDE equipment capable of 3G data communication, a terminal equipped with GPS-One function, a simple UI program that can calculate the terminal location (latitude, longitude, height) and the terminal location of others when it is known need.

현재, GPS-One은 단말기에서 IS 801 데이터 버스트 메시지(Data Burst Message)를 이용하여 긴급(Emergency) 모드에서 PCS(DCN) 모드와 GPS 모드를 교번되게 선택하면서 위성으로부터 지리정보를 획득하여 기지국에 전송한다. 이때, 상기 기지국에서는 입력된 지리정보를 근거로 단말기의 위치를 계산함과 아울러, 그 단말기가 GPS 신호를 수신하는 것을 지원하면서 위치정보를 단말기에 전송한다.Currently, GPS-One acquires geographic information from satellite and transmits it to the base station by alternately selecting PCS (DCN) mode and GPS mode in emergency mode using IS 801 Data Burst Message in the terminal. do. At this time, the base station calculates the location of the terminal based on the input geographic information and transmits the location information to the terminal while supporting the terminal receiving the GPS signal.

여기서, 상기 기지국에서 단말기로 전송되는 IS 801 데이터 버스트 메시지를 분석해 보면 그 단말기의 위도와 경도 및 높이의 정보를 얻을 수 있게 된다. 따라서, 본 발명에서는 타인의 IS 801 데이터 버스트 메시지를 별도로 전송받아 단말기간의 위치를 계산하고, 다시 각각의 단말기가 어느 정도의 거리에 있는지 알아내도록 하였다.Here, when the IS 801 data burst message transmitted from the base station to the terminal is analyzed, the latitude, longitude, and height of the terminal can be obtained. Therefore, in the present invention, the IS 801 data burst message of another person is separately received to calculate the position between the terminals, and to find out how far each terminal is.

또한, 매번 긴급 모드로 직접 진입하는 방법도 있지만 일정 시간 예를 들어 10분 또는 30분 간격으로 상대방 단말기의 위치를 자동 계산하고, 그 결과를 단말기에 디스플레이하되, 만약 적정 거리 이상 벗어난 경우에는 경고음을 출력하여 사용자가 그 사실을 인식할 수 있도록 하고, 자동으로 통화가 가능하게 하였다.In addition, there is a method to directly enter the emergency mode every time, but automatically calculates the location of the other terminal at a predetermined time, for example, every 10 or 30 minutes, and displays the result on the terminal. Printed out to allow the user to recognize the fact, and automatically enabled the call.

한편, 상기와 같은 위치 관측 처리과정을 도 1을 참조하여 좀더 상세히 설명하면 다음과 같다.Meanwhile, the above-described position observation processing will be described in more detail with reference to FIG. 1 as follows.

두 대의 단말기 중 보호자가 휴대하게 되는 기준 단말기와 나머지 한 대의단말기 즉 보호 대상의 어린이나 치매 노인이 휴대하게 되는 단말기(이하, "어린이용 단말기"라 칭함)가 긴급모드로 셋팅된다.(S1)Among the two terminals, the reference terminal to be carried by the guardian and the other terminal, that is, a terminal (hereinafter, referred to as a "child terminal") to be carried by a child to be protected or an elderly person with dementia, are set in an emergency mode.

상기 기준 단말기는 기지국으로부터 자신의 위치정보를 주기적으로 전송받아 업데이트하고, 상기 어린이용 단말기의 위치정보를 주기적으로 전송받아 체크하게 된다.(S2,S3)The reference terminal periodically receives and updates its location information from the base station, and periodically receives and checks the location information of the children's terminal (S2, S3).

또한, 상기 어린이용 단말기에서도 자신의 위치정보를 기지국으로부터 주기적으로 전송받아 업데이트하게 되며, 이 위치 정보를 자신의 ID(예: 전화번호 등)로 구별하여 상기 기준 단말기에 주기적으로 전송하도록 요구한다.(S4,S5)In addition, the child terminal periodically receives and updates its own location information from the base station, and distinguishes the location information by its own ID (eg, a telephone number) and requests it to be periodically transmitted to the reference terminal. (S4, S5)

일정 주기에서 또는 임의의 시점에서 상기 기지국에 상기 어린이용 단말기의 위치정보가 있는지 확인하여 그 위치정보가 없는 것으로 판명되면, 그 기준단말기에 알람을 출력한 후 기지국에 어린이용 단말기의 전원상태를 체크해 줄 것을 의뢰하고, 그 체크 결과 이상이 없는 것으로 판명되면 자동 통화 연결이 이루어지도록 한다.(S6,S7)If the base station checks the location information of the children's terminal at a certain period or at any point, and turns out that the location information does not exist, output an alarm to the reference terminal and check the power state of the children's terminal at the base station. If it is found that there is nothing wrong with the check, make an automatic call connection (S6, S7).

그러나, 상기 확인 결과 위치정보가 존재하면, 상기 기준 단말기는 자신의 위치정보를 근거로 위도와 경도 및 고도를 측정하고, 상기 기지국으로부터 전송받은 어린이용 단말기의 위치정보를 근거로 그 단말기의 위도와 경도 및 고도를 측정한 후, 두 단말기의 위치정보를 근거로 그 어린이용 단말기와의 거리를 산출하여 그 결과를 엘씨디 상에 디스플레이한다.(S8)However, if the location information exists as a result of the check, the reference terminal measures the latitude, longitude, and altitude based on its own location information, and based on the location information of the children's terminal received from the base station, After measuring the longitude and altitude, the distance between the children terminal is calculated based on the location information of the two terminals, and the result is displayed on the LCD.

상기와 같은 처리과정은 기 설정된 시간 주기로 반복 수행되거나, 기준 단말기의 요구가 있을 때마다 수행되며, 이전의 거리정보는 새로운 거리정보가 산출될때까지 계속 디스플레이된다.The above process is repeatedly performed at a preset time period, or every time a request of the reference terminal is requested, and the previous distance information is continuously displayed until new distance information is calculated.

이후, 상기 기준 단말기의 엘씨디에 디스플레이된 어린이용 단말기와의 거리를 기 설정된 기준거리와 비교하여 기준거리를 벗어난 것으로 판명되면, 기준 단말기에서 경고음을 출력함과 아울러, 자동적으로 어린이용 단말기로 다이얼링하여 어린이와 통화할 수 있도록 한다.(S9,S10)Subsequently, when it is determined that the distance from the child terminal displayed on the LCD of the reference terminal is out of the reference distance by comparing with the preset reference distance, the reference terminal outputs a warning sound and automatically dials the child terminal. Allows you to talk to children (S9, S10)

그러나, 상기 확인 결과 두 단말기간의 거리가 기준거리 이내인 것으로 판명되면 기준 단말기에서 위치정보를 계속 업데이트하여 엘씨디에 디스플레이한다.(S11)However, if it is determined that the distance between the two terminals is within the reference distance, the reference terminal continuously updates the location information and displays it on the LCD. (S11)

이상에서 상세히 설명한 바와 같이 본 발명은 3G 망이 구축되어 있는 시스템에서 GPS-One 알고리즘을 이용하여, 기준 단말기에서 아동용 단말기와의 거리를 일정 주기로 측정하여 엘씨디에 디스플레이하고, 그 거리가 일정치 이상으로 멀어질 때 경고음을 출력함과 아울러, 자동적으로 어린이용 단말기로 다이얼링하여 어린이와 통화할 수 있도록 함으로써, 광범위한 지역에서도 어린이나 치매 노인과 같은 보호 대상자를 보다 편리하고 확실하게 보호할 수 있는 효과가 있다.As described in detail above, the present invention uses a GPS-One algorithm in a system in which a 3G network is constructed, and measures the distance from a reference terminal to a child terminal at regular intervals and displays it on an LCD, and the distance is greater than or equal to a predetermined value. By outputting a warning sound when moving away and automatically dialing a child terminal to talk to a child, it is possible to more conveniently and reliably protect a protected person such as a child or an elderly person with dementia even in a wide area. .
