Abstract: A method for controlling interference in an audio service and a terminal, where the method includes sending, by a first terminal, a first message using a short-range wireless communications technology when executing an audio service, determining, by a second terminal according to the first message, whether the second terminal supports interference control, and adjusting, by the second terminal, a setting of the second terminal according to the interference control parameter when the second terminal supports the interference control, and the second terminal falls within a controlled range. It can be learned that in a process in which the first terminal performs interference control on the second terminal, the first terminal may send the first message to the second terminal without a need of a noise reduction device such that the second terminal adjusts the setting of the second terminal.

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 ni received 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 ni RSSs respectively corresponding to the k APs, and determining a target floor from the two candidate floors according to the atmospheric pressure change rate.
