Abstract
According to a method for handover between distributed access points, an AP 1 receives a handover request sent by a central AP, where the handover request includes an address of a wireless terminal and an identifier of an AP 2; and after receiving the handover request, the AP 1 sends a context handover request to the AP 2, where the context handover request includes an unsent frame of the wireless terminal. In a handover process, the AP 1 may send, to the AP 2, a buffered frame that fails to be sent to the wireless terminal in time, and send the frame to the wireless terminal by using the AP 2, so as to reduce a downlink packet loss when the wireless terminal is handed over between the AP 1 and the AP 2.
