Zusammenfassung:	The present invention relates to a method for correcting user terminal location information in an indoor space. When a user terminal enters the room, an indoor location information processing device is operated by global navigation satellite system (GNSS) signal loss, and a measurement value measured by a plurality of sensors included in a user terminal is transmitted. Based on the transmitted measurement value, in order to correct the indoor location of the user terminal using a predetermined algorithm, pedestrian dead reckoning (PDR) information is obtained, and the method is to correct the indoor space location information of the user terminal by comparing and processing the PDR information with built-in the indoor space information. A measurement value measured by the plurality of sensors (110) included in the user terminal (100) is received to correct the indoor space location information of the user terminal (100) based on the indoor space information stored in the indoor location information processing device (200). 본 발명은 사용자 단말이 실내로 진입하면 GNSS(Global Navigation Satellite System, 위성측위시스템) 신호 로스로 인한 실내위치정보 처리장치가 작동되어, 사용자 단말에 포함된 복수의 센서들에 의해 측정된 측정값을 전송받고, 전송된 측정값에 기초하여 사용자 단말의 실내위치를 보정하기 위해 사전설정된 알고리즘을 이용하여 PDR(Pedestrian Dead Reckoning, 보행자추측항법) 정보를 획득하며, 상기 PDR 정보를 내장된 실내공간정보와 비교처리에 의해 사용자 단말의 실내공간 위치정보를 보정하기 위한 실내 공간에서의 사용자 단말 위치정보 보정방법에 관한 것으로, 상기 사용자 단말(100)에 포함된 복수의 센서(110)에 의해 측정된 측정값을 전송받아 상기 실내위치정보 처리장치(200)에 저장된 실내공간 정보에 기반하여 상기 사용자 단말(100)의 실내공간 위치정보를 보정한다.
