Abstract
A method includes collecting m atmospheric pressure values and n groups of WI-FI information within a preset period, determining an atmospheric pressure change rate according to at least two of the m atmospheric pressure values, when an absolute value of the atmospheric pressure change rate is greater than a preset value, determining, according to the n groups of WI-FI information, k access points (APs) that send the n groups of WI-FI information and nreceived signal strengths (RSSs) respectively corresponding to the k APs, obtaining floors on which the k APs are respectively located, determining two candidate floors according to the floors on which the k APs are respectively located and the nRSSs respectively corresponding to the k APs, and determining a target floor from the two candidate floors according to the atmospheric pressure change rate.
