Rapid roaming method and system

Abstract

The invention discloses a rapid roaming method and a system, which relate to the technical field of wireless roaming, and aims to reduce roaming tables of a whole wireless network or uncontrollable roaming tables, provide a roaming table with high service quality for a client and reduce scanning of the client on a whole channel. When roaming occurs, the client initiates reconnection with the APs in the available roaming tables and switches to the APs in the available roaming tables, and as the authentication information of the client is synchronized to the target AP, AP switching can be completed with low delay. The APs of which the indexes such as the load and the time delay meet the set conditions are screened out from the surrounding AP list to generate the available roaming table, so that the load balance of the whole wireless network can be realized, and the usability of the wireless network and the usability of the client reach a balance state.

Description

technical field [0001] The invention relates to the technical field of wireless roaming, in particular to a fast roaming method and system. Background technique [0002] In WLAN (Wireless Local Area Networks, wireless local area network), applications that require delay, such as voice and games, must have certain requirements for the delay caused by switching AP (Access Point, access point), and switch to The service quality of the purpose AP also has certain requirements. However, the existing related technology is to collect the authentication information of the wireless client by the AP, and each AP must save the authentication information of all wireless clients and the information of all APs in the entire network, and the data efficiency is low; or the authentication information of the wireless client is collected by the AP. All wireless client authentication information and all AP information in the entire network are managed by the AC (Access Controller, Access Contr...

Problems solved by technology

However, the existing related technology is to collect the authentication information of the wireless client by the AP, and each AP must save the authentication information of all wireless clients and the information of all APs in the entire network, and the data efficiency is low; or the authentication information of the wireless client is collected by the AP. All wireless client authentication information and all AP information in the entire network are managed by AC (Access Controller, Access Controller). In this way, the interaction with AC is more frequent and the response is slower.

Both methods are only suitable for small and simple WiFi networks, and do not reflect the real purpose AP service quality
