실종사건이 발생하면 경찰은 실종자를 찾In the case of a missing person, police have been tracking the location of the base station, which they called in the range of 3 to 5 kilometers, after checking the data stored at the news agency to find the missing person. However, it is impossible to find a missing person as they are often in urban areas or hilly areas after tracking the location of the base station. In modern society, most of them carry cell phones from elementary school to old age group. In case of a missing persons case, convergence technologies such as cellular phone GPS receiver, the Internet of Things (IOT) where devices and people communicate, and location information technology about objects and people can be used to identify missing persons. When using a mobile phone using WiFi, if the location is a restaurant, movie theater, or cafe, the device information of the missing person, IP of the access terminal, the time of use, etc. are displayed on the sharing device installed on the mobile device of the missing person, and other data such as the address of the receiver (AP) are left on the missing person's mobile phone. In addition, these data can identify the movement, behavior analysis, criminal identification, and identification of accomplices using real-time location information of the missing persons, and real-time tracking of missing persons based on accurate indoor location. The disappearance should be resolved by utilizing the latest convergence technology related to mobile phones.기 위해 통신사에 보관된 자료를 확인하고 3-5km의 범위에 통화한 기지국 중심 위치추적을 해오고 있다. 그러나 기지국 중심 위치추적 후에 직접 방문을 해보면 도심지역이거나 야산인 경우가 많아서 실종자를 발견하는 것은 불가능하다. 현대사회에서 초등학생부터 노년부에 이르기까지 대부분 휴대폰을 소지하고 있다. 실종사건이 발생 할 경우에 휴대폰 GPS수신기, 기기와 사람 등이 소통하는 사물인터넷(IOT) 등 융복합기술, 사물과 사람에 대한 위치정보 기술 등은 실종자 발견에 적극 활용 할 수가 있다. 와이파이(Wifi)를 이용하여 핸드폰을 사용 할 때, 그 장소가 식당, 영화관, 카페 등일 경우, 현장에 설치되어 있는 공유기에 실종자의 기기 정보, 접속단말기의 IP, 사용시간 등이 표시되고, 실종자의 핸드폰에도 공유기(AP)의 주소 등 자료가 남게 된다. 또한 이러한 자료는 실종자의 실시간 위치 정보를 활용한 동선 분석 및 행동 분석, 범죄성여부 파악, 공범자 파악 등을 파악하고 정확한 실내 위치에 기반하여 실시간 실종자 추적을 실행할 수 있다. 휴대폰과 연관된 최첨단 융복합 기술을 적극 활용하여 실종사건이 해결되어야 한다.
