Method for switching wireless access controllers (ACs) and wireless access point (AP)

Abstract

The invention discloses a method for switching wireless access controllers (ACs) and a wireless access point (AP), which can ensure continuity of user services. The method comprises the following steps of: acquiring address information of a first AC and a second AC by the wireless AP, and acquiring wireless interface configuration information and tunnel interface configuration information from the first AC after the AP registers the first AC successfully; and when a network link between the AP and the first AC breaks, registering the second AC, acquiring new tunnel interface configuration information from the second AC, and implementing the user services by using the previously-acquired wireless interface configuration information and the newly-acquired tunnel interface configuration information from the second AC. The AP comprises an information acquisition module, a registration module and a service module. The method for ACs and the wireless AP of the embodiment of the invention are used to implement hot standby switching of the main and standby ACs, thereby avoiding interruption of the user services at a work station.

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 advancement of 3G services, many mobile operators are paying more and more attention to another technology-wireless local area network (WLAN), taking WLAN as an important supplement to 3G services, in hotspot areas with large data traffic Large-scale network construction, and actively guide users to use WLAN. [0003] Due to the complicated management of fat AP (wireless access point) before, WLAN network is not centralized and unified, and now it is gradually developing to the model of thin AP (wireless access point) + AC (wireless access controller). The advantages of thin AP + AC are AC uniformly configures and manages APs to facilitate network management data collection. [0004] In the thin AP mode, the administrator will not log in to the AP page to confi...

AI Technical Summary

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
