Problems solved by technology

[0002] In the existing Wi-Fi active scanning strategy, if the medium is detected to be busy within the MinChannelTime time, the STA stays scanning on each channel for MaxChannelTime, the MaxChannelTime is a fixed value, and, during channel scanning, the STA sends The number of probe requests is fixed, so there may be the following problems: all APs cannot be scanned out on channels with a large number of APs, and scanning time is wasted on channels with a small number of APs or even no APs piece

Abstract

The invention relates to a self-adaptive adjustment method and device for channel scanning time. The method comprises the following steps: acquiring a historical AP number of a channel according to ahistorical scanning result of the channel; and determining the scanning time of the channel according to the historical AP number. The scanning time of a current channel is determined according to a historical scanning result of the channel. According to the self-adaptive adjustment method and device for channel scanning time, the scanning time of the channel with a large number of APs is longer,the scanning time slice is prevented from being wasted on the channel with a small number of APs or even without APs, the distribution rationality of the channel scanning time is improved, more APs can be scanned by using less time, and the utilization of the scanning time slice is more efficient.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for adaptively adjusting channel scan time. Background technique [0002] In the existing Wi-Fi active scanning strategy, if the medium is detected to be busy within the MinChannelTime time, the STA stays scanning on each channel for MaxChannelTime, the MaxChannelTime is a fixed value, and, during channel scanning, the STA sends The number of probe requests is fixed, so there may be the following problems: all APs cannot be scanned out on channels with a large number of APs, and scanning time is wasted on channels with a small number of APs or even no APs piece. Contents of the invention [0003] In view of this, the present disclosure proposes a method and device for adaptively adjusting channel scan time. [0004] According to an aspect of the present disclosure, a method for adaptively adjusting channel scan time is provided, the m...
