Embodiment
It refer to schema, wherein identical element numbers represent identical component, principle of the invention is to implement one
Illustrated in appropriate computing environment.The following description is that, based on the illustrated specific embodiment of the invention, it should not be by
It is considered as the limitation present invention other specific embodiments not detailed herein.
It will be detailed below.
Referring to Fig. 1, Fig. 1 is the schematic flow sheet of filtering method provided in an embodiment of the present invention, the filtering method can be with
For terminal, the terminal can include the first wave filter and the second wave filter, and the insertion loss value of first wave filter can be with
More than the insertion loss value of second wave filter, flow can include：
In step S101, when detecting terminal using communication service, communication frequency is obtained.
In step s 102, the Wireless Fidelity working frequency of the terminal is obtained.
It is understood that the executive agent of the embodiment of the present invention can be the end of smart mobile phone or tablet personal computer etc.
End equipment.
Such as, due to Wireless Fidelity (wireless-fidelity, abbreviation WiFi) technical work 2.4GHz frequency ranges compared with
The frequency of low frequency part and Band40 higher-frequency part is approached, and higher-frequency part and the Band41 of WiFi 2.4GHz frequency ranges
The frequency of relatively low frequency part approach, therefore when WiFi works in 2.4GHz frequency ranges, while terminal uses Band40 or Band41
When frequency range is communicated, WiFi working frequency range is easily interfered to Band40 and Band41 frequency ranges.
In the step S101 and S102 of the embodiment of the present invention, communication service and Wireless Fidelity business are carried out simultaneously in terminal
When, terminal can first obtain its current communication frequency and Wireless Fidelity working frequency.
Afterwards, terminal can be detected between its current communication frequency and Wireless Fidelity working frequency with the presence or absence of interference.
There is interference between current communication frequency and Wireless Fidelity working frequency if detecting, then enter step
S103。
Interference is not present between current communication frequency and Wireless Fidelity working frequency if detecting, then enter step
S104。
In step s 103, there is interference between the communication frequency and the Wireless Fidelity working frequency if detecting, make
The Wireless Fidelity signal of the terminal is filtered with the first wave filter.
Such as, its current communication frequency that terminal is got is frequency range Band40 higher-frequency part (such as 2399MHz),
And currently used Wireless Fidelity working frequency is the low channel frequency of 2.4GHz frequency ranges, then terminal can consider current lead to
Believe there is interference between frequency and Wireless Fidelity working frequency.In this case, terminal can use insertion loss value larger
The first wave filter Wireless Fidelity signal is filtered.For example, the insertion loss value of the first wave filter can be 2dB.
It should be noted that insertion loss (abbreviation Insertion Loss) refers to some devices or element (such as wave filter or impedance matching
Device etc.) add a certain circuit when, the loss of energy or gain.Insertion loss is with the corresponding decibel of received signal level signal
(dB) represent.
It is understood that because the Out-of-band rejection ability of the larger wave filter of insertion loss value is relatively good, therefore logical
When believing between frequency and Wireless Fidelity working frequency in the presence of interference, Wireless Fidelity signal is filtered using the first wave filter,
The noise that Wireless Fidelity signal falls into communications band (Band40 or Band41) can be fewer, namely Wireless Fidelity signal is to communication
The influence of the radio-frequency performance of frequency range (Band40 or Band41) is smaller.
In step S104, interference is not present between the communication frequency and Wireless Fidelity working frequency if detecting, makes
The Wireless Fidelity signal of the terminal is filtered with the second wave filter.
Such as, its current communication frequency that terminal is got is 925.2MHZ, then terminal can consider current lead to
Believe and interference is not present between frequency and Wireless Fidelity working frequency.In this case, terminal can use insertion loss value compared with
The second small wave filter is filtered to Wireless Fidelity signal.For example, the insertion loss value of the second wave filter can be 1dB.
It is understood that when being filtered using the second wave filter to Wireless Fidelity signal, due to the second wave filter
Insertion loss value it is smaller, therefore Wireless Fidelity signal is it is small with interior Insertion Loss after the second filter filtering, i.e., wireless to protect
True signal decay is small.
In some described modes, the first wave filter and the second wave filter can be SAW filter (Surface
Acoustic Wave), or bulk accoustic wave filter (Bulk Acoustic Wave).
It is understood that in the embodiment of the present invention, terminal can be in current communication frequency and Wireless Fidelity working frequency
Between exist interference when, Wireless Fidelity signal is filtered using the first larger wave filter of insertion loss value.Because insertion is damaged
The Out-of-band rejection ability of the first larger wave filter of consumption value is better than less second wave filter of insertion loss value, therefore is using
When one wave filter is filtered to Wireless Fidelity signal, the noise for falling into communication frequency can be smaller, so as to reduce wireless guarantor
True interference of the working frequency to communication frequency.And when interference is not present in current communication frequency and Wireless Fidelity working frequency, make
Wireless Fidelity signal is filtered with insertion loss value less second wave filter.Due to the insertion loss value of the second wave filter
It is smaller, therefore Wireless Fidelity signal it is also smaller with interior Insertion Loss after the second filter filtering, i.e., Wireless Fidelity signal declines
Reduce.
Further, since the present embodiment can be carried out according to different situations with different wave filters to Wireless Fidelity signal
Filtering, therefore the present embodiment can also improve the flexibility that terminal-pair Wireless Fidelity signal is filtered.
Referring to Fig. 2, Fig. 2 is another schematic flow sheet of filtering method provided in an embodiment of the present invention, the filtering method
It can be used for terminal, the terminal can include the first wave filter and the second wave filter, the insertion loss value of first wave filter
The insertion loss value of second wave filter can be more than, flow can include：
In step s 201, when detecting using communication service, terminal obtains the communication frequency for data receiver.
In step S202, terminal obtains Wireless Fidelity working frequency.
Such as, step S201 and step S202 can include：
When using communication service and Wireless Fidelity business at the same time, terminal can obtain its current data receiver that is used for
Communication frequency (i.e. downstream frequency) and WiFi working frequencies.
In step S203, terminal calculates the frequency interval of the communication frequency and the Wireless Fidelity working frequency.
In step S204, terminal judges whether the frequency interval is less than or equal to predetermined interval threshold value.
Such as, step S203 and S204 can include：
After the current communication frequency of terminal and WiFi working frequencies is got, terminal can calculate the communication frequency
With the frequency interval of WiFi working frequencies.Then, terminal may determine that whether the frequency interval that the calculating is obtained is less than or equal to
Predetermined interval threshold value.
If it is judged that the frequency interval that the calculating is obtained is less than or equal to predetermined interval threshold value, then enter step
S205。
If it is judged that the frequency interval that the calculating is obtained is more than predetermined interval threshold value, then enter step S208.
In step S205, if judging, the frequency interval is less than or equal to predetermined interval threshold value, and terminal determines that this leads to
Believe there is interference between frequency and Wireless Fidelity working frequency.
In step S206, terminal is filtered using the first wave filter to Wireless Fidelity signal.
Such as, step S204 and S205 can include：
If it is judged that the frequency interval between the current communication frequency of terminal and WiFi working frequencies is less than or equal in advance
If interval threshold, then it is considered that the interval between communication frequency and WiFi working frequencies is smaller, there is interference therebetween.
In such a case, it is possible to which triggering terminal is filtered using the first wave filter to Wireless Fidelity signal.
For example, the currently used communication frequency of terminal is 2399MHz, and current WiFi working frequencies are 2412MHz.It is logical
It is 13MHz to believe the frequency interval between frequency and WiFi working frequencies.And predetermined interval threshold value is 30MHZ.In this case,
It is considered that current communication frequency is approached with WiFi working frequencies, interference (such as adjacent frequency interference) is easily produced therebetween, that
Terminal can use the first wave filter to be filtered WiFi signal.
It is understood that because the insertion loss value of the first wave filter is larger, therefore its Out-of-band rejection ability is preferable.Cause
When this has interference between communication frequency and WiFi working frequencies, WiFi signal is filtered using the first wave filter,
The noise that WiFi signal falls into communications band can be fewer, namely influence of the WiFi signal to the radio-frequency performance of communications band is compared
It is small.
In step S207, terminal switching communication frequency, and communication frequency and Wireless Fidelity after switching are being detected
When interference is not present in working frequency, terminal is filtered using the second wave filter to Wireless Fidelity signal.
Such as, after being filtered using the first wave filter to WiFi signal, if a terminal detects that downlink communication frequency
Changed, and interference is not present in downlink communication frequency and the Wireless Fidelity working frequency after changing, then terminal can be with
Do not use the first wave filter and carry out the filtering of WiFi signal, then WiFi signal is filtered using the second wave filter.
It is understood that when carrying out the filtering of WiFi signal using the first wave filter, due to inserting for the first wave filter
Enter loss value larger, therefore WiFi signal is by its, i.e. inband signaling decay larger with interior Insertion Loss after the first filter filtering
Larger, this transmitting-receiving performance on WiFi signal has certain influence.So, after communication service is stopped using, terminal can be with
Then WiFi signal is filtered using insertion loss value less second wave filter.
In step S208, if judging, the frequency interval is more than predetermined interval threshold value, and terminal determines the communication frequency
Interference is not present between Wireless Fidelity working frequency.
In step S209, terminal is filtered using the second wave filter to Wireless Fidelity signal.
Such as, step S208 and S209 can include：
If it is judged that the frequency interval between the current communication frequency of terminal and WiFi working frequencies is more than predetermined interval
Threshold value, then it is considered that the interval between communication frequency and WiFi working frequencies is larger, be not easy the presence of interference therebetween.
In this case, terminal can use the second wave filter to be filtered Wireless Fidelity signal.
For example, the current communication frequency of terminal is 925.2MHz, and current WiFi working frequencies are 2412MHz.Communication
Frequency interval between frequency and WiFi working frequencies is 1496.8MHz, and the frequency interval is more than predetermined interval threshold value 30MHz.
In such a case, it is possible to think that current communication frequency and WiFi working frequencies are distant, do not allow to be also easy to produce therebetween
Interference, then terminal can use the second wave filter to be filtered WiFi signal.
It is understood that when being filtered using the second wave filter to Wireless Fidelity signal, due to the second wave filter
Insertion loss value it is smaller, therefore Wireless Fidelity signal is it is small with interior Insertion Loss after the second filter filtering, i.e., wireless to protect
True signal decay is small, it is hereby achieved that preferably WiFi signal transmitting-receiving performance.
In another embodiment, the present embodiment can also judge the current communication frequency of terminal as follows
With the presence or absence of interference between Wireless Fidelity working frequency：
According to Wireless Fidelity working frequency, corresponding present channel is determined；
If detecting communication frequency is in default communications band, and the present channel is corresponding with the default communications band
Preset channel, it is determined that there is interference between communication frequency and Wireless Fidelity working frequency；
If detecting communication frequency is not at default communications band, or the present channel is not and the default communications band pair
The preset channel answered, it is determined that interference is not present between communication frequency and Wireless Fidelity working frequency.
For example, after WiFi working frequencies are got, terminal can determine that its is corresponding according to the WiFi working frequencies
Present channel.
After the channel of WiFi works at present is determined, it is pre- that terminal can detect whether its communication frequency used is in
If communications band, and detect whether the present channel of WiFi work is preset channel corresponding with the default communications band.
If detecting that the communication frequency that terminal is used is in default communications band, and detect the current of WiFi work
Channel is preset channel corresponding with the default communications band, then terminal can determine communication frequency and WiFi working frequencies
Between exist interference.
For example, default communications band includes default first communications band and default second communications band, wherein default first
The frequency range of communications band is 2350~2399MHz (frequency range Band40 higher channel part), presets the second communications band
Frequency range be 2496~2541MHz (frequency range Band41 relatively low channel strip).It is corresponding with default first communications band
WiFi preset channels are 1~No. 7 channel (WiFi relatively low channel), WiFi preset channels corresponding with default second communications band
For 8~No. 13 channels (WiFi higher channel).
So, for example when the communication frequency for detecting terminal is in default first communications band, and WiFi working frequencies
When corresponding present channel is in 1~No. 7 channel, terminal can determine there is interference between communication frequency and WiFi frequencies.
That is, communicated using Band40 higher channel part when detecting terminal, and WiFi is when working in relatively low channel, can recognize
To there is interference between communication frequency and WiFi working frequencies.Or, lead to when the communication frequency for detecting terminal is in default second
Believe frequency range, and the corresponding present channel of WiFi working frequencies be in 8~No. 13 channels when, terminal can determine communication frequency with
There is interference between WiFi frequencies.That is, communicated when detecting terminal using Band41 relatively low channel strip, and WiFi
When working in higher channel, it is believed that there is interference between communication frequency and WiFi working frequencies.
If detecting the communication frequency that terminal uses is not at default communications band, or WiFi work present channel
It is not preset channel corresponding with the default communications band, then it is considered that not deposited between communication frequency and WiFi working frequencies
In interference.If that is, detecting communication frequency is not at default communications band, then can be with communication frequency and WiFi works
Interference is not present between working frequency.Or, if detecting communication frequency is in default communications band, but WiFi working frequencies pair
The present channel answered is not preset channel corresponding with the default communications band, then can be with communication frequency and WiFi working frequencies
Between be not present interference.
For example, communication frequency is both not at default first communications band, not also in default second communications band, then can
To think interference is not present between communication frequency and WiFi working frequencies.Or, communication frequency is in default first communications band, but
WiFi working frequencies are in 3~No. 8 channels, then it is considered that interference is not present between communication frequency and WiFi working frequencies.Again
Or, communication frequency is in default second communications band, but WiFi working frequencies are in 1~No. 7 channel, then it is considered that logical
Believe and interference is not present between frequency and WiFi working frequencies.
In one embodiment, the present embodiment can also comprise the following steps：
Detecting after terminal stops using communication service, Wireless Fidelity signal is being filtered using the second wave filter.
For example, after being filtered using the first wave filter to Wireless Fidelity signal, terminal can be detected whether
Stop using communication service.
If detecting terminal not yet stops using communication service, then terminal can be continuing with the first wave filter to nothing
Line Fidelity signal is filtered.
If detecting terminal has stopped using communication service, then terminal can transfer using the second wave filter to nothing
Line Fidelity signal is filtered.
It is understood that being switched to by the first wave filter after the second wave filter, terminal can obtain more preferable nothing
Line Fidelity signal filter effect.
3A to Fig. 3 C is referred to, Fig. 3 A to Fig. 3 C are the schematic diagram of a scenario of filtering method provided in an embodiment of the present invention.
For example, terminal includes the first wave filter and the second wave filter, wherein the insertion loss value of the first wave filter is more than the
The insertion loss value of two wave filters.Terminal carries out data transmission with Wireless Fidelity access point (Access Point, abbreviation AP)
While, also communicated with base station, as shown in Figure 3A.
In this case, terminal can first obtain the communication frequency (i.e. downstream frequency) that it is used for data receiver, and
Wireless Fidelity WiFi working frequencies.
Afterwards, terminal can calculate the frequency interval between the communication frequency and WiFi working frequencies.For example, terminal is obtained
The downlink communication frequency arrived is the 2399MHz of Band40 frequency ranges, and WiFi working frequencies are 2412MHz, then terminal is calculated and obtained
Communication frequency and WiFi working frequencies between frequency interval be 13MHz.
Then, whether the frequency interval that terminal can be obtained with interval calculation is less than or equal to predetermined interval threshold value.For example,
Predetermined interval threshold value is 30MHz.So, terminal will detect that the frequency interval is less than predetermined interval threshold value.
Frequency interval 13MHz between downlink communication frequency 2399MHz and WiFi working frequency 2412MHz is detected is small
After predetermined interval threshold value 30MHz, terminal can determine there is interference between the downlink communication frequency and WiFi working frequencies.
Then, terminal can use the first wave filter a to be filtered Wireless Fidelity signal.Now, the work of wireless fidelity module is shown
Intention can be as shown in Figure 3 B.
For example, after some time has elapsed, user finishes communication service, namely terminal detects and stops using communication
Business, then terminal can not use the first wave filter a to be filtered Wireless Fidelity signal, but use second to filter
Device b is filtered to Wireless Fidelity signal.Now, the operating diagram of wireless fidelity module can be as shown in Figure 3 C.
Referring to Fig. 4, Fig. 4 is the structural representation of filter provided in an embodiment of the present invention.Filter 300 can be with
Including：First acquisition module 301, the second acquisition module 302, the first filtration module 303, and the second filtration module 304.
The filtering terminal 300 goes for terminal, and the terminal can include the first wave filter and the second wave filter, and this
The insertion loss value of one wave filter is more than the insertion loss value of second wave filter.
First acquisition module 301, for when detecting the terminal using communication service, obtaining communication frequency.
Second acquisition module 302, the Wireless Fidelity working frequency for obtaining the terminal.
Such as, communication service is carried out simultaneously and during Wireless Fidelity business, the first acquisition module 301 of terminal can be with terminal
Its current communication frequency is first obtained, and WiFi working frequencies are obtained by the second acquisition module 302.
Afterwards, terminal can be detected between its current communication frequency and Wireless Fidelity working frequency with the presence or absence of interference.
First filtration module 303, if being deposited for detecting between the communication frequency and the Wireless Fidelity working frequency
In interference, then the Wireless Fidelity signal of the terminal is filtered using first wave filter.
Such as, if terminal, which is detected, has interference between its current communication frequency and Wireless Fidelity working frequency, then
First filtration module 303 can use the first wave filter to be filtered Wireless Fidelity signal.
For example, the current downlink communication frequency of the terminal that gets of the first acquisition module 301 is the higher of frequency range Band40
Frequency part (such as 2399MHz), and the current Wireless Fidelity working frequency of terminal that the second acquisition module 302 is got is 2.4GHz
The low channel frequency of frequency range, then terminal can consider to be existed between currently used communication frequency and Wireless Fidelity working frequency
Interference.In this case, the first filtration module 303 can use the first larger wave filter of insertion loss value to Wireless Fidelity
Signal is filtered.
Second filtration module 304, if for detecting between the communication frequency and the Wireless Fidelity working frequency not
In the presence of interference, then the Wireless Fidelity signal of the terminal is filtered using second wave filter.
Such as, if terminal, which is detected, is not present interference between its current communication frequency and Wireless Fidelity working frequency, that
Second filtration module 304 can use the second wave filter to be filtered Wireless Fidelity signal.
For example, the currently used communication frequency of the terminal that gets of the first acquisition module 301 is 925.2MHZ, then terminal
It is considered that interference is not present between current communication frequency and Wireless Fidelity working frequency.In this case, the second filtering
Module 304 can use less second wave filter of insertion loss value to be filtered Wireless Fidelity signal.
In one embodiment, the first acquisition module 301 can be used for：
Obtain the communication frequency for data receiver.
Such as, when terminal uses communication service, the first acquisition module 301, which can obtain the terminal, is used for data receiver
Communication frequency.That is, the first acquisition module 301 can obtain the downlink communication frequency of terminal.
It is understood that the influence for the radiofrequency signal that WiFi working frequencies are received to terminal is than larger, and to transmitting
Radiofrequency signal influence very little, therefore the first acquisition module 301 can be made to obtain the communication frequency for data receiver.
Please refer to fig. 5, Fig. 5 is another structural representation of filter 300 provided in an embodiment of the present invention.One

Computing module 305, the frequency interval for calculating the communication frequency and the Wireless Fidelity working frequency；If inspection
The frequency interval is measured less than or equal to predetermined interval threshold value, it is determined that the communication frequency works frequently with the Wireless Fidelity
There is interference between rate；If detecting the frequency interval more than predetermined interval threshold value, it is determined that the communication frequency with it is described
Interference is not present between Wireless Fidelity working frequency.
In one embodiment, terminal can be by detecting whether frequency interval is less than or equal to predetermined interval threshold value
Mode is judged between two frequencies with the presence or absence of interference.
For example, after the communication frequency and WiFi working frequencies that terminal uses is got, computing module 305 can be calculated
The communication frequency and the frequency interval of WiFi working frequencies.Then, computing module 305 may determine that between the frequency that the calculating is obtained
Every whether less than or equal to predetermined interval threshold value.
If detecting the frequency interval less than or equal to predetermined interval threshold value, then computing module 305 can be determined
There is interference between the currently used communication frequency of terminal and WiFi working frequencies.
If detecting the frequency interval more than predetermined interval threshold value, then computing module 305 can determine that terminal is worked as
Interference is not present between the preceding communication frequency used and WiFi working frequencies.
Handover module 306, for detecting terminal switching communication frequency, and communication frequency after switching with it is described
Wireless Fidelity working frequency is not present after interference, and Wireless Fidelity signal is filtered using second wave filter.
Such as, after being filtered using the first wave filter to WiFi signal, if a terminal detects that downlink communication frequency
Changed, and interference is not present in downlink communication frequency and the Wireless Fidelity working frequency after changing, then terminal can be with
Do not use the first wave filter and carry out the filtering of WiFi signal, then WiFi signal is filtered using the second wave filter.
I.e., it is possible to be filtered by the control terminal of handover module 306 using the second wave filter to Wireless Fidelity signal.
Determining module 307, for according to the Wireless Fidelity working frequency, determining corresponding present channel；If detecting
The communication frequency is in default communications band, and the present channel is default letter corresponding with the default communications band
Road, it is determined that there is interference between the communication frequency and the Wireless Fidelity working frequency；If detecting the communication frequency
