Abstract:
A method for a handover between distributed access points is disclosed, including receiving, by a central AP, an Ethernet frame; adding, by the central AP, a sequence number to the frame according to an address of a wireless terminal; sending, by the central AP to an AP 1, the frame to which the sequence number is added, and storing the frame to which the sequence number is added in a historical frame set of the wireless terminal; and sending, by the central AP, a frame in the historical frame set of the wireless terminal to an AP 2 when the wireless terminal is handed over from the AP 1 to the AP 2. If the wireless terminal moves fast, the central AP can send the frame in the historical frame set to the wireless terminal using the AP 2, so that a downlink packet loss is reduced.
