All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. Unless otherwise defined, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. As used herein, the word "comprising" and the like means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof without precluding other elements or items.
In view of the problems existing in the prior art, an embodiment of the present invention provides a channel control method of a wireless access point, which is applied to a mobile terminal, and referring to fig. 1, the method includes the following steps:
s101, after the mobile terminal starts a software hotspot, obtaining channel related information around the mobile terminal when the position offset of the mobile terminal reaches a preset offset.
In some embodiments, the obtaining the channel related information around the mobile terminal when the position offset of the mobile terminal reaches a preset offset includes:
and acquiring the number of hot spot occupation of each channel around the mobile terminal and the received signal strength indication (Received Signal Strength Indicator, RSSI) in each channel to obtain the channel related information.
After the mobile terminal starts a software hotspot (Soft Access Point, softAP), when the mobile terminal is not moving, the surrounding channel environment is in a fixed state, so that the corresponding channel can be quickly determined after the mobile terminal starts the SoftAP, and when a user moves, the mobile terminal moves along with the mobile terminal, the channel environment around the mobile terminal also changes, and at the moment, the channel originally used by the mobile terminal is not necessarily the most excellent channel, so that in the moving process of the mobile terminal, when the moving offset reaches the preset offset, the channel environment information around the mobile terminal is obtained, wherein the channel environment information comprises the heat occupation number of each channel around the mobile terminal and the received signal strength indication in each channel, so that the number of the heat occupation in each channel and the received signal strength indication can be sequenced, and the channels meeting the requirements can be conveniently and quickly screened out.
Wherein the preset offset is at least greater than a coverage diameter of a software hotspot of the mobile terminal, such as 30m.
S102, comparing and screening the channel related information according to the pre-input channel input condition to select a screened channel meeting the requirement.
In some embodiments, the comparing and screening the channel related information according to the pre-input channel input condition to select a screened channel meeting the requirement includes:
ordering each channel according to the number of hot spots in the channel and the received signal strength indication;
selecting a plurality of channels with the number of hot spots smaller than a first threshold value from the sorted channels as initial channels according to the channel input conditions;
and acquiring the signal strength RSSI of each hot spot in the initial channel, and selecting the initial channel of which the signal strength is lower than a second threshold value in the initial channels as the screening channel.
In this embodiment, after determining the channel input condition, the number of occupied hot spots in each channel around the mobile terminal and the received signal strength indicator RSSI of each hot spot in the channel are ordered so as to determine the number of hot spots and the hot spot strength in each channel, so as to select a channel that satisfies the channel input condition. Specifically, the channels with the number of hot spots smaller than the first threshold are selected as initial channels according to the number of hot spots occupied in the channels, then the channels are selected according to the signal intensity of the hot spots in each channel in the initial channels, when the hot spots with the signal intensity higher than or equal to the second threshold exist in the initial channels, the stronger signal interference exists in the current channels, the channels are not suitable to be used as screening channels, and only when the signal intensity of each hot spot in the initial channels is lower than the second threshold, the current initial channels are used as the screening channels.
The channel input condition is that channel interference is minimum, and when the signal intensity of each hot spot in the plurality of initial channels is smaller than a second threshold value, the initial channel with the smallest hot spot number is selected as a screening channel.
In still other embodiments, any one of the first, sixth, and eleventh channels is selected as the screening channel when the number of hot spot occupancy in each of the channels is 0.
S103, adjusting the current channel of the software hotspot to a target channel according to the difference between the current channel of the software hotspot and the screening channel.
In some embodiments, the adjusting the current channel of the software hotspot to the target channel based on the difference between the current channel of the software hotspot and the screening channel comprises:
after determining that the current channel of the software hotspot and the screening channel have differences, calling a related interface through the mobile terminal to set a channel according to the differences of the current channel and the screening channel so as to set the current channel as the target channel;
and after the current channel of the software hotspot is determined to be consistent with the screening channel, keeping the current channel of the software hotspot consistent.
After screening out the screening channel, the mobile terminal compares the current channel of the software hotspot with the selected screening channel, if the current channel of the software hotspot and the selected screening channel have a difference, the mobile terminal adjusts the current channel of the software hotspot to the screening channel according to the difference, so that a target channel of the software hotspot is obtained to reduce interference of external signals, and when the screening channel and the current channel of the software hotspot have no difference, the current channel of the software hotspot of the mobile terminal does not need to be adjusted.
For example, referring to fig. 2, the channel related information is obtained in real time through a sensor to obtain the channel related information of APs around the mobile terminal, the mobile terminal compares the channel related information with the channel input condition through a comparator, and a controller in the mobile terminal adjusts the channel of the software hot spot of the mobile terminal according to the compared difference, so as to ensure that the mobile terminal can keep transmitting signals in a good channel environment after moving to reduce external interference of the hot spot signals in the channel, and improve user experience.
The invention also provides a channel control device of the wireless access point, which is applied to the mobile terminal, and referring to fig. 3, the method comprises the following steps:
the information obtaining module 301 is configured to obtain, after the mobile terminal opens a software hotspot, channel related information around the mobile terminal when the position offset of the mobile terminal reaches a preset offset;
