Embodiment Construction

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] Currently, in order to implement STA roaming, if the network includes multiple access devices, the recorded roaming entries need to be synchronized among the multiple access devices. This needs to consume a lot of network resources, and has a great impact on the normal services of the access device. Especially for Fat APs with poor processing performance, the synchronization of roaming entries has a more serious impa...

Abstract

Embodiments of the present application provide a roaming method and device, which are applied to monitoring equipment. The solution includes: acquiring first parameter information of a first AP, second parameter information of multiple second APs, and third parameter information of STAs; determining the first real-time The running status scoring value, the second real-time running status scoring value of each second AP, and according to the third parameter information, determine the real-time communication status scoring value of the STA on the first AP; when the real-time communication status scoring value is lower than the preset scoring value threshold, determine the optional AP from multiple second APs; estimate the predicted communication state score value of the STA on each optional AP; determine the optional AP with the largest predicted communication state score value as the target AP, and record the The roaming entry of the STA is delivered to the target AP. By applying the technical solutions provided by the embodiments of the present application, it is possible to realize roaming while reducing consumption of network resources and reducing impact on normal services of access devices.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a roaming method and device. Background technique [0002] In a complex network environment, in order to provide a better user experience on the Internet, a roaming function is provided in the network. Specifically, when a STA (Station, station) is associated with an AP (Access Point, access point) and accesses the network through an access device such as an AC (AccessController, access controller) or a Fat AP (fat access point), The associated AP of the STA records the roaming entry of the STA, and sends the roaming entry of the STA to the access device. The roaming table entry includes an identifier of a VLAN (Virtual Local Area Network, virtual local area network) to which the STA belongs, an IP (Internet Protocol, network protocol) address of the STA, and the like. The access device records the roaming entry of the STA. When the AC or Fat AP determi...
