A method, performed by an electronic device, of identifying location information of an external includes the steps of: obtaining map information including location information for each time interval of a mobile device based on the mobile device moving while generating noise near the external device; obtaining audio signal information about an audio signal including the noise generated by the mobile device, the audio signal being collected by a microphone of the external device; identifying, from the audio signal information, a time point at which a noise level of the noise generated by the mobile device is highest; obtaining, from the map information, location information of the mobile device corresponding to the identified time point; and identifying the location information of the external device based on the obtained location information of the mobile device. Accordingly, the location of the external device may be automatically identified based on the noise generated according to the movement of the mobile device. 이동 장치가 외부 장치의 근처에서 소음을 발생시키면서 이동함에 따라, 시간대별 상기 이동 장치의 위치 정보를 포함하는 맵 정보를 획득하고, 외부 장치의 마이크에 의하여 수집된, 이동 장치에 의해 발생된 소음을 포함하는 오디오 신호에 관한 정보를 획득하고, 오디오 신호에 관한 정보에서, 이동 장치에 의해 발생된 소음의 크기가 최대인 시점을 식별하고, 맵 정보로부터, 식별된 시점과 대응되는, 이동 장치의 위치 정보를 획득하고, 획득된 이동 장치의 위치 정보에 기초하여, 외부 장치의 위치 정보를 식별하는, 전자 장치에서, 외부 장치의 위치 정보를 식별하는 방법이 제공된다.
