It is sent to mobile terminal 1 00.
Based on above-mentioned mobile terminal hardware configuration and communication system, each embodiment of the inventive method is proposed.
First embodiment
As shown in figure 3, a kind of wireless network that first embodiment of the invention is provided runs the system of selection of channel, the side
Method includes step：
30th, the trigger signal of channel preferred function button is obtained.
In the present embodiment, channel preferred function button can be set at the interface of mobile terminal, triggers the preferred work(of the channel
Energy button can enable channel preferred function.Channel preferred function specifically can be obtained by pressure sensor or proximity transducer to press
The trigger signal of button.
In the present embodiment, channel (Channel) is further division to frequency range (by 5G or 2.4G band limits
Several small frequency ranges are further subdivided into, each frequency range is referred to as a Channel), there is " 5.18GHZ ", " Auto (DFS) " etc., place
In different transmission channel data above, if channel coverage is not overlapping, then will not interfere.For channel
Use, there is defined in the world.Some of which channel without authorize i.e. can be used directly (be actually that frequency range that
Individual channel, different according to every country), meant without licensing, it is (no matter wireless with which kind of when transmission data
Mode), the data when power that equipment can be allowed to receive and dispatch causes to transmit enter the frequency and the frequency range where the channel of the channel
It is transmitted in width；Using for mandate is meant, is not allowed to carry out using authorization channel during transmission, otherwise can be violated rule
It is fixed, and disturb the transmission of other data on the channel.In addition, except WiFi, microwave, infrared ray, bluetooth (are assisted using 802.15
View) working frequency range also have in the range of 2.4GHZ, so, they transmit when can to WiFi transmission interfere,
Because both are communicated under different agreements, the signal identification for mutually transmitting other side is noise.It is wireless in configuration
When focus (Access Point, AP), there is the option value of one similar " Auto " in Channel, this represents to open AP's
When, the environment around AP oneself scannings selects the minimum Channel of an interference to be communicated, when having chosen one
When Channel, it would not typically change.
31st, according to the trigger signal of the channel preferred function button of acquisition, start wireless network card work and start letter simultaneously
Mark frame processing service.
In the present embodiment, starting wireless network card work includes opening Wi-Fi hotspot or WiFi.
WiFi is a kind of technology for allowing electronic equipment to be connected to a WLAN (Wireless LAN, WLAN),
Usually using 2.4G UHF or 5G SHF ISM radio frequency bands.
32nd, handled and serviced by beacon frame, obtain the beacon management frame in surrounding wireless environment, beacon management frame is carried out
Analyzing and processing, and according to preferred channel ordering rule, obtain preferred channel sorted lists.
In the present embodiment, beacon management frame (also known as beacon frame, Beacon frames) is a management frame in 802.11 agreements,
Beacon frame timing broadcast transmissions, are mainly used to notify the existence of network wireless focus (Access Point, AP).Access station
When point (Station, STA) and AP set up connection, it is also desirable to use Beacon frames.STA can be scanned by scanning
Beacon frames, so as to learn AP presence, can also be sent by active when scanning and detect claim frame (Probe
Request) it whether there is to seek AP.That is, having the scanning or passive scanning two of active when setting up connection
The mode of kind.In addition, Beacon frames further comprises on information such as Power Save and areas.
In the present embodiment, network operation letter in wireless environment around can be obtained by analyzing and processing being carried out to beacon management frame
