A SYSTEM AND METHOD TO REDUCE MEDIA ACCESS CONTROL (MAC) LAYER HANDOFF LATENCY

摘要

The present invention relates to system and method for MAC layer handoff which comprises of multiple access points, a mobile device, and an access controller. It is used to minimize MAC layer handoff latency in centralized WLAN network and obviate scanning time during MAC layer handoff process. It is also used to reduce number of probed channels and waiting time for each channel response during probing phase. The system comprises at least one mobile device (110) connected to an access point (120), at least two access points (120), and an access controller connected to the at least two access point (120). The at least one mobile device (110) includes an AP Channel Receiver (111), the access controller (130) includes a Next AP Selector (140); and each access point (120) includes a Received Signal Strength Inspector (142).
