Abstract

The embodiment of the invention provides a method, device and system for finding out a wireless access point, aiming to achieve the purposes of rapidly finding out an available access point and saving the electric quantity for a mobile terminal STA (station). In the method, a base station controller (BSC) receivers a request message sent by the mobile terminal STA, acquires one or more AP (Access Point) information nearby the STA from an access controller (AC), and sends a notice message to the STA so as to make the STA actively scan and find out the corresponding AP based on a service set identifier (SSID).
