Abstract
A method includes obtaining first movement information of a to-be-located device. The method also includes obtaining a target time threshold based on the first movement information. The method further includes obtaining a first scan timestamp corresponding to a target time and a first media access control MAC address, where the target time is a fingerprint collection time of a first fingerprint or a maximum value of a scan timestamp corresponding to at least one MAC address included in the first fingerprint. The first MAC address is included in the first fingerprint. The method additionally includes, if a difference between the target time and the first scan timestamp is greater than the target time threshold, determining that access point information corresponding to the first MAC address is residual access point information.
