Abstract: This application discloses a terminal roaming method and apparatus. A terminal sends, to a first AP associated with the terminal, an action frame that is used to request to associate with a second AP. A receiver address of the action frame is an address of the first AP, and the action frame further includes an identifier of the second AP. When the terminal receives a response frame sent by the first AP for the action frame, and the response frame indicates that association succeeds, the terminal establishes association with the second AP. The terminal first establishes the association with the second AP by using the first AP, and then changes an operating channel to an operating channel of the second AP. Now the terminal can receive and send data on the operating channel of the second AP.

Abstract: A channel indication sending method, a channel scanning method, and an apparatus are disclosed. The sending method includes: A first access point receives channel information from a second access point, where the channel information indicates that an operating channel of the second access point is a first channel, and whether the second access point successfully performs channel availability check (CAC) on the first channel, and the first channel is a dynamic frequency selection (DFS) channel. The first access point sends, on a second channel, a WLAN frame to a station associated with the first access point, where the WLAN frame includes an indication about the first channel and an indication of whether the second access point successfully performs the CAC on the first channel.
