Embodiment Construction

[0041] According to the existing technology, for the detection of the quality of the bidirectional link of the wireless connection, the existing technology uses the AP to send a detection message to the STA, and obtains the connection between the STA and the AP according to the response message returned by the STA to the detection message obtained by the AP. Signal strength value, however, the prior art solution cannot determine the signal strength from the AP to the STA. Since the wireless connection is bidirectional, when adjusting the connection, if you can know the signal strength (Receive Signal Strength Indicator, RSSI) from the wireless AP to the STA, and the signal strength from the STA to the AP, then the pertinence of the connection adjustment is stronger.

[0042] In view of the above problems, an embodiment of the present invention provides a method for detecting the quality of a wireless link, the method may include the following steps:

Abstract

The invention provides a wireless link quality detection method and device. The method includes the steps that according to acquired transmitting power of a terminal STA, transmitting power between an AP and the STA is adjusted, and the AP sends a detection message to the STA according to the adjusted transmitting power of the AP; based on a response message, returned by the STA for the detection message, acquired by the AP, a signal intensity value from the STA to the AP and current transmitting power of the STA are acquired; according to the transmitting power of the AP before adjustment, the signal intensity value from the STA to the AP and the current transmitting power of the STA, a signal intensity value from the AP to the STA is determined. By the adoption of the wireless link quality detection method and device, the problem that in the prior art, signal intensity from the AP to the STA cannot be determined is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting the quality of a wireless link. Background technique [0002] At present, the application of Wireless Local Area Networks (WLAN) has become more and more popular, and the following problems are network deployment and how administrators can accurately grasp the operation status of the entire network, especially the signal coverage status. The transmission medium of WLAN is air. When a terminal (station, STA) is successfully connected to an access point (Access Point, AP), it needs to know the link quality of this connection in order to make adjustments. [0003] The implementation of the existing wireless link quality test is: use the AP to send a message to the STA, and obtain the signal strength value of the STA response message. However, the signal strength is the signal strength value from the STA to the AP, and the prior art solution ...
