A method for processing wireless access, comprising: composing, by one or more network controllers, a signaling control subnetwork; composing, by multiple forwarding devices that connect with each other in the form of reticulation, a data exchange subnetwork; a wireless access controller, AC, being deployed independently, or integrated in the control subnetwork; wireless access points, APs, being directly connected to the multiple forwarding devices of the data exchange subnetwork or connected to the multiple forwarding devices of the data exchange subnetwork through a switch, the forwarding device that is connected to the AP is a home forwarding device of the AP; the forwarding device matching media access control, MAC, according to a manufacturer AP MAC address field table stored by itself, establishing and maintaining an AP table for local access, and sending report information to the network controller; and the one or more network controllers establishing a corresponding relationship table between entire network APs and their home forwarding devices, and maintaining the corresponding relationship table according to report information of the forwarding device, wherein the corresponding relationship table comprises fields: AP media access control, MAC, a forwarding device network identification, and latest accessing time; the signaling control subnetwork instantly calculating user's data trend exchange policy and flow table, and sending the exchange policy and flow table to the data exchange subnetwork, the data exchange subnetwork forwarding user data according to the exchange policy and flow table; and the data stream of a terminal is transmitted by the data exchange subnetwork, without passing through the AC. composing, by one or more network controllers, a signaling control subnetwork; composing, by multiple forwarding devices that connect with each other in the form of reticulation, a data exchange subnetwork; a wireless access controller, AC, being deployed independently, or integrated in the control subnetwork; wireless access points, APs, being directly connected to the multiple forwarding devices of the data exchange subnetwork or connected to the multiple forwarding devices of the data exchange subnetwork through a switch, the forwarding device that is connected to the AP is a home forwarding device of the AP; the forwarding device matching media access control, MAC, according to a manufacturer AP MAC address field table stored by itself, establishing and maintaining an AP table for local access, and sending report information to the network controller; and the one or more network controllers establishing a corresponding relationship table between entire network APs and their home forwarding devices, and maintaining the corresponding relationship table according to report information of the forwarding device, wherein the corresponding relationship table comprises fields: AP media access control, MAC, a forwarding device network identification, and latest accessing time; the signaling control subnetwork instantly calculating user's data trend exchange policy and flow table, and sending the exchange policy and flow table to the data exchange subnetwork, the data exchange subnetwork forwarding user data according to the exchange policy and flow table; and the data stream of a terminal is transmitted by the data exchange subnetwork, without passing through the AC.
