METHOD FOR HANDOVER BETWEEN DISTRIBUTED APS, CENTRAL AP, AND DISTRIBUTED AP

摘要

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 Ethernet frame according to an address of a wireless terminal; sending, by the central AP to an AP 1, the Ethernet frame to which the sequence number is added, and storing the Ethernet 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 by using the AP 2, to replace a frame that is buffered in the AP 1 and has not been sent to the wireless terminal, so that a downlink packet loss during a handover of the wireless terminal between the AP 1 and the AP 2 is reduced.
