METHOD FOR MIGRATION OF AP OF STATION IN ORDER TO RESOLVE WIRELESS LINK FAILURE

摘要

A system for migration of an access point (AP) of a station in order to resolve a wireless failure which occurs in a wireless LAN environment, according to an embodiment, comprises: a hidden terminal detection unit for detecting a wireless failure which occurs in a plurality of APs connected to a centralized controller; an AP selection unit which, if a wireless failure occurring in the APs is detected, generates an AP list by aligning the ranking of the APs for reconnection in descending order, and provides a migration message including the AP list to a victim station; and an NTP server unit for performing time synchronization by providing reference time to the plurality of APs.
