Embodiment 1

[0024] This embodiment provides a method for selecting a WLAN frequency point, such as figure 1 shown, including:

[0025] In step 101, the access node AP receives an instruction to monitor the wireless environment from the access controller AC.

[0026] For example: you can first enter the configuration command on the AC to modify all AP modes, and change the normal forwarding mode of the AP to the monitor (Monitor) mode. In this mode, the AP can collect the wireless environment information of the environment.

[0027] Among them, the wireless environment information mainly includes: AP device address, AP uplink signal strength, AP signal ID, AP signal frequency, AP configured transmit power, AP adjacent signal frequency, AP adjacent signal frequency The signal strength of the point, the signal ID of the signal frequency points adjacent to the AP, and the uplink signal strength.

[0028] Step 102, the AP collects wireless environment information according to the instruction...

Embodiment 2

[0099] In order to facilitate the implementation of the method in Embodiment 1, this embodiment provides a device for selecting a WLAN frequency point, which may be installed in the WLAN platform in Embodiment 1, or may be the WLAN platform in Embodiment 1. Such as figure 2 As shown, it includes: a receiving module 21 , a selecting module 22 and a determining module 23 .

[0100] The receiving module 21 is used to receive the wireless environment information collected by the access node AP; the selection module 22 is used to select the optimal frequency point for the AP in the current wireless environment according to the wireless environment information; the determination module 23 is used for Determine whether the currently configured frequency of the AP is the optimal frequency based on the wireless environment information and the optimal frequency.

[0101] Among them, the wireless environment information includes: AP device address, AP uplink signal strength, AP signal ...

Abstract

The invention discloses a WLAN frequency point selection method and relates to the technical field of wireless communication and solves a technical problem that in the prior art, work load is increased in frequency point reselection because of poor stability of WLAN frequency points. The method mainly includes the following steps: a WLAN platform selects a frequency point, which is optimal to an AP under a current wireless environment, according to wireless environment information reported by the AP; and the WLAN platform determines whether the frequency point which is currently configured is the optimal frequency point according to the wireless environment information and the optimal frequency point. The WLAN frequency point selection method and device are mainly used for WLAN.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for selecting a WLAN frequency point. Background technique [0002] In recent years, domestic operators have vigorously built WLAN networks, but currently WLAN networks use 2.4G and 5.8G public frequency bands, and there are only 3 and 5 frequency bands that do not interfere with each other, so it is easy for the frequency points to interfere with each other. As a result, it is difficult to avoid network quality problems caused by frequency interference during routine WLAN network maintenance. [0003] In the prior art, the solution to network problems caused by frequency point interference in the WLAN can only rely on on-site testing by maintenance personnel. The maintenance personnel use the WLAN test instrument to scan the frequency and select the frequency point with the highest carrier-to-interference ratio at that time. [0004] ...
