Embodiment 1

[0075] figure 1 It is a flowchart of a channel allocation method according to Embodiment 1 of the present invention. Such as figure 1 As shown, the channel allocation method mainly includes:

[0076] Step S110, the AC determines multiple candidate channel configurations, any one of the multiple candidate channel configurations includes a candidate working channel of each access point AP to which a channel is to be allocated.

[0077] Specifically, the WLAN may include ACs such as network switches, routers, and servers, APs such as wireless routers, home gateways, and wireless network interface controllers (English: wireless network interface controller, abbreviated: WNIC), and non-AP STAs such as mobile phones and tablet computers. , e-books and other terminal equipment. Among them, the non-AP STA can access the Internet through the AP and the AC.

[0078] Before the AC determines multiple candidate channel configurations, it can combine the WLAN channel list to obtain t...

Abstract

The invention discloses a channel allocation method, a channel allocation device and a wireless local area network system, wherein the channel allocation method includes: determining a plurality of candidate channel configurations; The interference intensity distribution under each candidate channel configuration in the channel configuration; according to the interference intensity distribution under each candidate channel configuration in multiple candidate channel configurations, select the system with the least interference or the most stable system from multiple candidate channel configurations The candidate channel configuration corresponding to the interference intensity distribution is used as the actual channel configuration; the candidate working channel of the AP of each channel to be allocated in the selected candidate channel configuration is used as the actual working channel of the AP of each channel to be allocated. The channel allocation method of this embodiment can dynamically adjust the actual working channel of the AP to be allocated a channel, reduce the interference between APs, effectively use the channel bandwidth, increase the data transmission rate, and improve the system throughput.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a channel allocation method, a channel allocation device and a wireless local area network system. Background technique [0002] With the rapid development of wireless communication technology, wireless local area network (English: wireless local area network, abbreviation: WLAN) has been widely used in homes, offices, and public places. A common WLAN architecture includes: a WLAN controller, a wireless access point (English: access point, abbreviated: AP), and a non-AP station (English: station, abbreviated: STA). An AP is a device that provides wireless access. The WLAN controller is usually used to manage and control the AP, and provide service configuration for the AP. The WLAN controller may be an access controller (English: Access Controller, abbreviated: AC) complying with Request for Comments (English: Request for Comments, abbreviated: RFC) 5417. The non-AP S...
