Wireless access method, device and system, access controller, access point device

Abstract

The invention discloses a wireless access method, a wireless access device, a wireless access system, an access controller and access point equipment. After CAPWAP tunnels of APs entering an operation state, a first Keeplive message is sent to an AC, the AC triggers the CAPWAP tunnels corresponding to the APs to enter into the operation state, the AC joins logic nodes of the APs on an online processing queue, the AC alternatively carries out online processing and CAPWAP message processing; when the AC carries out online processing, the AC respectively carries out online processing and sends corresponding configuration request messages for the corresponding APs of the multiple AP logic nodes in the online processing queue; when the AC carries out CAPWAP message processing, the AC constructs and sends response messages according to the multiple AP logic nodes from the APs, so when a large number of the APs are accessed to the AC, a problem of breaking of the CAPWAP tunnels of partial APs caused by over-large load of the AC is solved.

Description

technical field [0001] The present invention relates to a network communication system, in particular to a wireless access method, device and system, an access controller, and an access point device. Background technique [0002] In the wireless local area network (WLAN, WirelessLocalAreaNetworks) "thin" access point (AP, AccessPoint) architecture, the AP needs to access the access controller (AC, AccessControl), that is, successfully establishes the wireless access point control and provisioning (CAPWAP) with the AC. , Controlling and Provisioning of Wireless Access Point) tunnel, and after the AC goes online to the AP and sends a configuration request message to the AP, and the AP performs configuration according to the configuration information carried in the configuration request message, the AP can normally provide various wireless clients (STA, Station) services, such as figure 1 shown. [0003] When the AP accesses the AC, it follows the RFC5415 CAPWAP protocol spec...

AI Technical Summary

Problems solved by technology

[0016] In view of this, embodiments of the present invention provide a wireless access method, device and system, an access controller, and an access point device to solve the problem of a large number of APs accessing the AC in an existing thin AP WLAN environment. , the CAPWAP tunnels of some APs are disconnected due to the heavy load and limited processing capacity of the AC
