Problems solved by technology

[0006] However, these two evaluation methods can only test the downlink signal interference. The uplink signal interference is mainly judged by the signal strength and uplink rate of the on-site test, and the abnormality of the interference-related indicators may be caused by other reasons. Such as weak network coverage, AP device problems, etc., so it is impossible to accurately evaluate the uplink interference of WLAN network users

Embodiment Construction

[0025] Due to the shortage of WLAN network resources, multiple network operators reuse limited frequency resources. When the channels of multiple APs are adjacent, the AP will not only receive the uplink signal of the terminal, but also receive the signal of the adjacent AP. , so there is signal interference between APs.

[0026] The WLAN network terminal uplink interference evaluation device can be implemented in the form of software and / or hardware, and the method includes:

[0027] Step S100, according to the preset reporting granularity, successively acquire terminal signal parameters of the terminal and AP signal parameters of adjacent APs, the terminal signal parameters include the terminal uplink signal strength, and the AP signal parameters include adjacent AP channel and Adjacent AP uplink signal strength;

[0028] Step S102: Calculate and obtain the inter-channel interference factor of the adjacent AP according to the channel of the adjacent AP, and calculate and ob...

Abstract

The invention discloses a WLAN network terminal uplink interference evaluation method and a device. the method comprises the following steps: according to the preset report granularity, terminal signal parameters of a terminal and AP signal parameters of an adjacent AP are successively obtained; according to a channel of the adjacent AP, interchannel interference factors of the adjacent AP are obtained though calculation; according to uplink signal intensity of the terminal, uplink signal intensity of the adjacent AP and the interchannel interference factors, each first uplink signal to noise ratio of the terminal is obtained through calculation; according to the each first uplink signal to noise ratio of the terminal, interference percentage of the frequency that the first uplink signal to noise ratio is less than the preset uplink signal to noise ratio in the report frequency is calculated; and whether the interference percentage is greater than the preset interference percentage is determined; and if the interference percentage is greater than the preset interference percentage, it is determined that there is interference during the business process of the terminal with the use of a WLAN network. The uplink signal to noise ratio is directly calculated through present acquisition parameters. Thus, accuracy of evaluating the uplink interference situation of WLAN network users is raised.

Description

technical field [0001] The present invention relates to the communication technology in the communication network, in particular to a WLAN network terminal uplink interference evaluation method and device. Background technique [0002] As major operators vigorously promote the deployment and construction of Wireless Local Area Networks (WLAN for short) and launch of various mobile Internet devices, the WLAN wireless network has become an important carrier of data services. However, due to the shortage of spectrum resources in the WLAN network, multiple operators reuse limited frequency point resources, resulting in the troubleshooting of wireless access point (AccessPoint, AP for short) interference problems has become a technical difficulty in WLAN network optimization. [0003] In the prior art, there are mainly two methods for checking whether there is interference in the uplink of WLAN network users: [0004] Method 1, relying on test instruments for on-site measurement...
