A Roaming Control Method Applied to Cluster AP

Abstract

The invention discloses a roam control strategy applied to cluster APs. The roam control strategy comprises the steps that S100, network equipment is initialized, an AC sets the same SSID for all the APs, and the MAC addresses of all the APs are different; S200, the AC determines the AP which is firstly selected to be accessed to each mobile terminal according to a proportional fairness principle, and each mobile terminal is connected with the determined corresponding AP; S300, the AC sequentially determines the APs needing to be switched by all the mobile terminals according to the proportional fairness principle, and completes switching within a timing cycle. According to the roam control strategy applied to the cluster APs, the AC is connected to a controller in a wireless local area network and actively conducts roam control over all the APs in the wireless local area network, management is centralized and unified, the connection relation between the mobile terminals and the APs is determined according to the bandwidth utilization rate of the APs by the proportional fairness principle, the load balance of all the APs in the network at any time is guaranteed as far as possible, the wireless service quality of the mobile terminals which the APs are accessed to is guaranteed, the complexity is low, implementation is easy, and extra hardware cost can be avoided.

Description

technical field [0001] The invention belongs to the technical field of communication networks, and in particular relates to a roaming control strategy based on AP active control applied to cluster APs. Background technique [0002] With the rapid development of the 802.11 wireless local area network (WLAN) technology, a large number of wireless local area networks based on wireless access points (AccessPoint, AP) are widely used. Wireless LAN equipment can provide unrestricted free mobility, enabling users to truly realize broadband network access anytime, anywhere and at will. [0003] For the large-scale deployment of APs within a certain range, the traditional method is that the mobile terminal can independently select an AP that can provide high wireless service quality according to its own roaming strategy, and switch among many APs. Specifically, if the mobile terminal itself adopts an inactive roaming strategy, as long as the mobile terminal can still scan the signal...

AI Technical Summary

Problems solved by technology

Specifically, if the mobile terminal itself adopts an inactive roaming strategy, as long as the mobile terminal can still scan the signal of the original Service Set Identifier (SSID), it will still use the original SSID instead of Select a new SSID with better signal quality, it is difficult to guarantee the quality of service

If the mobile terminal adopts an aggressive roaming strategy, it may roam repeatedly due to small signal strength changes, resulting in frequent interruption of data transmission

In short, the traditional way is that the mobile terminal selects AP access through its own way, which completely depends on the roaming strategy of the mobile terminal itself, and cannot realize active control and unified management. Therefore, handover efficiency, quality of service (QoS) requirements and load Balancing and other optimization measures are difficult to guarantee
