Method for guiding client to access AP (Access Point) and AC (Access Controller)

Abstract

The invention provides a method for guiding a client to access an AP and an AC. The method comprises the steps: detecting the communication quality of a first client accessing a first AP, obtaining a second AP accessed by the first client before the first client accesses the first AP when the communication quality of the first client is detected to reach a preset condition, a target path table matched with the first AP and the second AP is obtained from a path library with the first AP and the second AP as indexes, historical records of a third AP accessed by the first client side after the first client side accesses the first AP are recorded in the target path table, and the target path table is sent to the first client side. The first client accesses the third AP according to the target path table. Through the method, the AC can guide the client to select the AP needing to be accessed.

Description

Technical field [0001] The present disclosure relates to the field of wireless communication technology, and more particularly to a method and AC that guides client access AP. Background technique [0002] WLAN (WiReless LAN, Wireless LAN) is increasingly widely used, and users have gradually improved the roaming experience of wireless networks, requiring wireless clients to move to where to connect to Near AP (Access Point, Wireless Access Point). [0003] AC (Access Controller, centralized controller) centralized management AP. The wireless client actively recognizes the network environment during the mobile, and discovers the new AP, and then access the new AP, the entire roaming process, which is a client active behavior. There are many types of wireless clients, and all client vendors are different. Some manufacturers are too sensitive to generate oscillations. Some roaming is too unactivated to cause roaming viscous and can't roam to signal good APs, and eventually. [0004...
