Section Fen Biewei [50,40), [40,30), [30,20) and [20,0], as shown in Figure 2 a, such as W1=9, W2=8, W3=7, W4
=8, W5=10, then w1+w2+w3+w4+w5=42, determines the corresponding Qu Jian [ of the sum of Information Channel Index of channel 1;50,40) letter, is determined
The channel grade in road 1 is height.
Step S203, the described terminal determines the destination channel in N number of channel according to channel grade, to wireless access point
AP sends the first channel adjustment order, and the first channel adjustment order is used to indicate the AP and working channel is adjusted to described
Destination channel.
Wherein, terminal with AP there is binding relationship, i.e. terminal to possess the administrator right of the AP, can change the work letter of AP
Road.At this stage, modification AP working channels need to log in 192.168.1.1 network address, after administrator's authentication passes through, in terminal
Interface selects channel, and the channel that AP selects user is as working channel.
Optionally, 2.4GHZ frequency ranges are filtered out according to channel grade and the corresponding channel grade of 5GHZ frequency ranges is highest
Channel determines that the highest channel of respective channel grade is the destination channel of two frequency ranges.
Further, if the highest channel quantity of channel grade is multiple, the terminal acquisition highest letter of channel grade
The bit error rate in road determines that the channel of bit error rate minimum is the destination channel, wherein obtain the concrete mode of the bit error rate of channel
May include：Terminal instruction AP randomly chooses a channel as working channel in the highest channel of multiple channel grade,
When terminal and when AP transmission datas, obtain the bit error rate of the channel, then, from the highest channel of remaining channel grade again with
Machine selects a channel as working channel, obtains the bit error rate, until having obtained the mistake of the highest channel of multiple channel grade
Code check；It is of course also possible to according to the sum of Information Channel Index of the highest channel of channel grade from big to small or from small to large suitable
Sequence obtains the bit error rate of the highest channel of multiple channel grade successively, and the application, which does not limit, obtains the specific of channel bit error rate
Mode.
Optionally, the concrete mode for obtaining channel bit error rate may include：In transmission data, terminal receives and stores AP
The first coding data sent by the first channel；First coding data described in terminal-pair carries out error-correction decoding operation；To
When one coded data error correction decoding is successful, the terminal obtains the first information source data, is carried out to the first information source data anti-
To coding, the second coded data is obtained；The terminal determines institute according to the first coding data and second coded data
State the bit error rate of the first channel.
Further, it is determined that the channel of bit error rate minimum is destination channel in multiple highest channel of channel grade.
Optionally, after determining destination channel, by touching display screen to user's display target channel, in order to user hand
It is dynamic the working channel of AP is adjusted to this to state destination channel；In the technical solution of the application, after determining destination channel, terminal to
AP sends channel adjustment order, and working channel is adjusted to the destination channel by instruction AP.
For example, such as terminal and the connection of the 2.4GHZ frequency ranges of AP, such as determine that destination channel is the channel of 2.4GHZ frequency ranges
1, AP after verifying the terminal as with the terminal of administrator right, receives the channel adjustment order of terminal transmission, from the letter
It identifies that destination channel is channel 1 in road adjustment order, working channel is adjusted to channel 1 automatically, solves and manually adjusts AP
The trouble of working channel.Certainly, working channel as current such as AP is exactly channel 1, and AP will not adjust working channel, and can be to
Terminal feedback channel adjusts as a result, the channel adjustment result is for prompting user AP to be operated in channel 1, if switches to LTE
Network or prompt user's adjustment are at a distance from AP.
As can be seen that terminal obtains the parameter value of N number of channel, the distribution shape of the resource of each channel is determined by parameter value
State, the channel parameter values in the application eliminate the AP and non-AP that leaves unused in channel in the distribution state for determining channel resource and interfere
Factor accurately determines that working channel is adjusted to destination channel by destination channel, concurrent channels adjust instruction, instruction AP,
It solves the trouble for manually adjusting AP working channels, improves user experience；Moreover, if the highest channel quantity of channel grade
When being multiple, the bit error rate of the highest channel of multiple channel grade is obtained, determines that the channel of bit error rate minimum is destination channel,
By way of obtaining the bit error rate, selected from the highest channel of multiple channel grades the most stable of channel of transmission data as
Destination channel further increases the network performance of AP, improves user experience.
It is the flow diagram of another channel selecting method provided by the embodiments of the present application, the side refering to Fig. 3, Fig. 3
Method is applied to terminal, the method includes：
Step S301, in transmission data, such as detect that Ping values are more than predetermined threshold value, terminal sends channel probe request
Probe Request。
Optionally, capable of being opened by one key pattern can also be set, and user can control terminal sends channel at any time by touch control operation
Probe requests thereby Probe Request.
Wherein, Ping values refer to the time that terminal sends data to AP feedback data to AP, i.e., terminal sends internet control
Messaging protocol ICMP (Internet Control Message Protocol, abbreviation processed：ICMP) request is to AP, when AP can not
When forwarding data packet by current transmission rate, can automatic feedback ICMP response messages, carry in the ICMP response messages from
ICMP requests are initially received to the response time of feedback ICMP response messages, terminal, which parses the ICMP response messages and obtains, to be worked as
Preceding Ping values.Therefore, Ping values are higher shows that the time of AP reply datas is longer, postpones longer, the transmission rate of AP and terminal
It is smaller.
Wherein, which is specifically as follows 60ms, 80ms, 100ms or other values.
Step S302, the described terminal receives the probe response Probe Answer of each channel feedback, parses the Probe
Answer obtains the parameter value of each channel.
Step S303, the described terminal determines the channel grade of each channel in N number of channel according to the parameter value.
Step S304, the described terminal determines the destination channel in N number of channel according to channel grade, to wireless access point
AP sends channel adjustment order, and the channel adjustment order is used to indicate the AP and working channel is adjusted to the target letter
Road.
Optionally, when the highest channel quantity of channel grade is multiple, because Slot Count numbers and FCS numbers are to determine
Whether the channel also has the major parameter of slack resources, by comparing the Slot Count in the highest channel of multiple channel grades
Number and FCS numbers, select Slot Count numbers and the relatively small channel of FCS numbers as target from the highest channel of channel grade
Channel.
Step S305, the described terminal obtains the first transmission rate and the second transmission rate, and such as first transmission rate is small
In second transmission rate, the difference of second transmission rate and first transmission rate, first transmission are determined
Rate is the transmission rate of AP distribution, and second transmission rate is the transmission rate needed for the terminal.
Optionally, after working channel is adjusted to destination channel by AP, the first transmission rate, such as the first transmission rate are obtained
Still less than the second transmission rate, it is likely to the number of devices being connect with AP is excessive, causes the channel resource that terminal is got less,
At this point, in the case where not improving the bandwidth situation of AP and carrier server, it is desirable to reduce the channel resource of other-end meets this
The transmission demand of terminal is all that manually mode comes limiting terminal and the transmission rate of AP at present.
Step S306, the described terminal is determined according to the difference needs increased first running time-frequency resource, is sent to the AP
Bandwidth adjustment instructs, and the Bandwidth adjustment instruction is used to indicate the AP and adjusts the terminal according to first running time-frequency resource
Running time-frequency resource.
In the prior art, in order to not generate interference when realizing multiple terminal devices with AP transmission datas, when AP is generally used
Divide the mode transmission data of multiplexing or frequency division multiplexing.The application is illustrated for by the way of frequency division multiplexing.
Optionally, terminal is determined according to the difference is needing increased first resource of frequency range, to the AP transmission bandwidths
Adjust instruction, wherein Bandwidth adjustment instruction carries the IP address including the terminal, and AP is according to IP address in destination channel
Corresponding second resource of frequency range of the IP address is searched, is instructed according to the Bandwidth adjustment and second resource of frequency range is adjusted to third frequency range
Resource, wherein+the second resource of frequency range of the resource of frequency range of the third resource of frequency range=first, it is to be understood that by the frequency range of the terminal
When resource increases by second resource of frequency range, if needed the frequency range of other-end without the resource of frequency range of leaving unused in the destination channel
Otherwise resource first resource of frequency range of corresponding reduction will will produce frequency range overlapping, be interfered in transmission data.
For example, the frequency range for such as AP in destination channel being the terminal distribution is f1~f2 and the first transmission rate is
V, the transmission rate for defining unit frequency range are V/ (f2-f1), such as difference △ V of the second transmission rate and the first transmission rate, really
Determine AP to need for the increased resource of frequency range of terminal to be △ W=△ V* (f2-f1)/V, the terminal transmission bandwidth adjust instruction, indicate
AP inquires the corresponding frequency range f1~f2 of the terminal, and f1~f2 frequency ranges are adjusted to f1~(f2+ △ W).
Wherein, the frequency range for reducing other access terminals may include：The terminal being connect with AP is subjected to priority ranking, it will
The frequency range of the terminal (such as smart television, intelligent refrigerator, etc.) of low priority reduces △ W.
Further, when detecting that the first transmission rate is more than or equal to the second transmission rate, terminal is increased
First frequency range △ W cancel, and release and limit the frequency range of other-end, when AP uses time-multiplexed mode, first determine and need
Increased duration determines that method is similar with frequency domain, no longer narration in detail.
As can be seen that when terminal detects that Ping values are more than predetermined threshold value, the automatic letter searched for and determine surrounding channel
Road grade determines that working channel is adjusted to destination channel, improves the network of AP by destination channel, instruction AP according to channel grade
Performance, effective solution network interim card problem.Moreover, after working channel is adjusted to destination channel by AP, it is still unsatisfactory for end
The transmission demand at end then adjusts the distribution of AP channel resources, for the more channel resources of the terminal distribution, therefore can not carry
In the case of the bandwidth of high AP and carrier server, further solves the problems, such as network interim card, improve user experience.

When to the T1 moment, third channel adjustment order is sent to the AP, the third channel adjustment order is used to indicate the AP will
Working channel is adjusted to first working channel.
Wherein,
The V1 is the downlink transmission rate of the first object channel, and the V2 is the downlink of first working channel
Transmission rate, the T be the Video Applications broadcasting video total duration, the broadcastings video for the Video Applications
The video of broadcasting；The T0 is the playing time for playing video, that is, when clicking the broadcasting broadcasting video, playing progress bar
At the time of upper display；The W be the broadcastings video from the T0 to the buffer memory of the T, i.e., current video format (clearly
Clear degree) under, the flow value needed for T is watched from T0.
For example, as user is watching the video under super clear format《XX》, the total duration of video T=2 hours, video
Whole buffer memories be 2GB, if user is continuous from 1 hour from, i.e. T0=1 hours, W=1GB, such as V1=0.5M/S, V2=
0.25M/S, then can obtain T1=4096 seconds ≈ 1.14 hours, so at when the video playing is small to 1.14, instruction AP is by work
Channel adjustment is first working channel.
As can be seen that when watching video, working channel is adjusted to the first object channel of current location by instruction AP, is obtained
The downlink transmission rate for obtaining high speed shortens buffering duration when playing video, improves user experience.But it is always maintained at
The downlink transmission rate of high speed, power consumption is high, and electric quantity consumption is fast.So the application is buffered using the downlink transmission rate of high speed
