Information synchronizing method and access controller

Abstract

The invention discloses an information synchronizing method and an access controller. The access controller can send synchronous enabled information to an access point connected with the access controller. After the access point receives the synchronous enabled information, the access point can send terminal information of wireless users connected with the access point, and then the access controller is accessed to compare the received terminal information of the wireless users with terminal information of wireless users in local storage. Thus, which wireless user terminals that the local doesn't contain and which wireless user terminals that the access point doesn't contain can be learned, wireless user terminal information between the local and the access point can be synchronized according to comparison results, wireless terminal user data between the local and the access point can be identical, billing or authentication errors caused by the fact that the wireless terminal user data are not identical are avoided, and satisfaction of user experience is improved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an information synchronization method and an access controller. Background technique [0002] With the deployment of 3G networks and the popularization of smart phones and notebook computers, the demand for wireless data has shown explosive growth. 3G technology itself cannot support the huge demand for wireless data services. WLAN (Wireless Local Area Network, Wireless Local Area Network) technology, as a supplement to 3G coverage, realizes the offloading of 3G services through WLAN, improves user perception, and reduces investment costs, thereby promoting WLAN products and network construction from IT level to telecom operator level change. [0003] The traditional WLAN network is based on the "fat" AP (access point, Access Point, and the access point can be a wireless switch) architecture. The WLAN network is composed of mutually independent access point APs. The above ...

Problems solved by technology

Unfortunately, some abnormal situations, such as poor contact of the wireless network card of the AP, the network cable of the AP being unplugged due to accidental factors (or the network cable is loose), poor network conditions, etc., will cause the STA information on the AP and AC to be inconsistent, and then cause the calculation to fail. Fee or authentication errors, reducing user experience satisfaction
