Embodiment Construction

[0026] The embodiment of the invention discloses a roaming processing method and device, which can shorten the roaming processing time and improve the smoothness of roaming. In order to better understand the embodiments of the present invention, the application scenarios of the embodiments of the present invention are firstly described below.

[0027] see Figure 6 , Figure 6 It is a schematic diagram of a terminal roaming scene in a wireless local area network disclosed in an embodiment of the present invention, as shown in Figure 6 The shown wireless local area network may include multiple access points, managed by multiple wireless local area network controllers, for example, the access point AP1 is managed by the wireless local area network controller 1, and the access point AP2 may be managed by the wireless local area network controller 2, Optionally, the wireless local area network controller 1 can also manage multiple access points, such as access point AP3, access...

Abstract

The embodiment of the invention discloses a roaming processing method and device. In the roaming processing method, a wireless local area network controller maintains a roaming neighbor table for a plurality of access points according to the roaming behavior of at least one terminal, wherein the plurality of access points comprise a first access point and a second access point, and in the roaming neighbor table, the second access point is the neighbor of the first access point; and when a first terminal is connected to the first access point, the wireless local area network controller sends connection data of the first terminal to the second access point. Therefore, according to the method provided by the embodiment of the invention, when a terminal is connected with an access point, connection data of the terminal is sent to the neighbor of the access point, and a condition that the acquisition of the terminal connection data is triggered again when the terminal roams to the neighbor of the access point is avoided, so that the roaming processing time is shortened, and the roaming fluency is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a roaming processing method and device. Background technique [0002] One of the advantages of a wireless local area network (English: wireless local area network, abbreviation: WLAN) over a wired network is to support terminal mobility. When the terminal moves between the coverage areas of different access points (English: accesspoint, AP for short) of the WLAN, in order to keep the service of the terminal uninterrupted, it is necessary to ensure that the terminal roams among the APs. In some large-scale WLAN networks, the number of APs is relatively large, and multiple wireless LAN controllers are required to manage many APs. When a terminal sends an association request to a roaming AP, the roaming AP sends the association to its AC. Request, when the AC determines that the terminal is a roaming terminal according to the terminal's identity, it can find the AC...
