Problems solved by technology

[0006] 1. After the link between the AP and the active AC is disconnected, the AP switches to the standby AC. Since the IP address is the same, after the AP successfully joins the standby AC, it does not know whether the main link is restored or the standby link is switched. The flag bit tells whether the configuration needs to be delivered, and the configuration will be re-delivered, and the hot standby switch cannot be realized;
[0007] 2. Two sets of ACs are connected to the same ATCA (Advanced Communication Computing Architecture) frame at the same time. Since the data between the AP management control board and the user service access board in the two sets of ACs are forwarded by the same switch board, if The IP addresses of the AP management control boards are the same, so the user service access board cannot determine which AP management control board is the main control board, so it cannot be applied to the same ATCA chassis network

Embodiment 1

[0069] In this embodiment, after the AP and the two ACs are properly networked, AP grouping and WLAN configuration parameters are pre-set on the active and standby ACs, and the two AC addresses are configured in the option field of the AP address pool information of the active and standby ACs. One AC address is the address of the active AC, and the second AC address is the address of the standby AC. The state (including the AC state and interface state) is judged by the heartbeat detection between the active and standby ACs. In this embodiment, the AP is from the active AC. Obtain the addresses of the active and standby ACs, and the user's business is in the centralized tunnel forwarding mode, such as figure 1 shown, including the following steps:

[0070] Step 101: The AP initiates a Discover message of the CAPWAP protocol to the AC networking with it to obtain an address;

[0071] Step 102: The active AC receives the Discover message sent by the AP, replies with a DHCP resp...

Embodiment 2

[0086] In this embodiment, after APs and ACs are properly networked, AP groups and WLAN configuration parameters are pre-set on the active and standby ACs, and two AC addresses are configured in the option field of the AP address pool information of the active and standby ACs, where the first The first AC address is the address of the active AC, and the second AC address is the address of the standby AC. The state (including the AC state and interface state) is judged by the heartbeat detection between the active and standby ACs. In this embodiment, the AP obtains the master AC from the active AC. The standby AC address, the user's business is in the local forwarding mode, as shown in 2, including the following steps:

[0087] Step 201: The AP sends a Discover message to the AC in the network with it, requesting to obtain an address;

[0088] Step 202: The active AC receives the Discover message sent by the AP, replies to the offer message, and carries the address of the activ...

Embodiment 3

[0101] In this embodiment, after APs and ACs are properly networked, AP groups and WLAN configuration parameters are pre-set on the active and standby ACs, and the state (including AC state and interface state) is judged through heartbeat detection between the active and standby ACs. On the external DHCP server that supports option field configuration, set the addresses of the active and standby ACs. The first AC address is the address of the active AC, and the second AC address is the address of the standby AC. In this embodiment, the AP obtains the primary and secondary AC addresses from an external DHCP server that supports option field configuration. The flow chart is shown in Figure 3, which includes the following steps:

[0102] Step 301: The AP initiates a Discover message to the DHCP server, requests to obtain an address, parses the relevant option field in the offer message replied by the DHCP server, and obtains the active and standby AC addresses;

[0103] Step 302:...

Abstract

The invention discloses a wireless access controller switching method and a wireless access point, which ensure that user services are not interrupted. The method includes: a wireless access point (AP) obtains address information of a first AC and a second AC, and after the AP successfully registers with the first AC, obtains wireless interface configuration information and tunnel interface configuration information from the first AC; After the network link between the AP and the first AC is disconnected, it initiates registration with the second AC, obtains new tunnel interface configuration information from the second AC, and uses the previously obtained wireless interface configuration information and obtains the new tunnel interface configuration information from the second AC. Tunnel interface configuration information implements user services. The AP includes an information acquisition module, a registration module and a service module. The embodiment of the present invention realizes the hot standby switchover of the main AC and the standby AC, and avoids service interruption of workstation users.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless access controller switching method and a wireless access point. Background technique [0002] With the in-depth promotion of 3G services, many mobile operators pay more and more attention to another technology - wireless local area network (WLAN), and regard WLAN as an important supplement to 3G services. Large-scale network construction, and actively guide users to use WLAN. [0003] Due to the complex management of fat APs (wireless access points) in the WLAN network, which was not centralized and unified, it is gradually developing to the model of thin APs (wireless access points) + AC (wireless access controller). The advantages of thin APs + ACs are The AC uniformly configures and manages the APs, facilitating network management data collection. [0004] In the thin AP mode, the administrator will not log in to the AP page to configure parameters. Only when...
