Part, particularly frequency band B40, B41, B7 etc. are composed, B40 is located at the lower section of WLAN frequency ranges, and B41 and B7 are located at the upper of WLAN frequency ranges
Side, therefore when LTE is in above band operation, is all inevitably present and disturbs with WLAN, and according to current process water
Flat, coexisting filter, which is not ensured that, eliminates the interference of adjacent frequency section.
Such as, when mobile terminal scans wireless access points AP in the way of active scan, it can send out on each channel
Go out probe request, ask some ad hoc wireless networks to be responded, thus in scanning, mobile terminal can launch request letter
Number.Mobile terminal is in connection AP not successfully (such as without AP keys), and mobile terminal at regular intervals will be around active scan

LTE speech businesses, when detecting mobile terminal and currently carrying out LTE speech businesses, directly perform step S202；When detecting shifting
When dynamic terminal does not currently carry out LTE speech businesses, step S209 is directly performed.
In step S202, LET band informations used in LTE speech businesses are determined.
In step S203, WLAN band information and corresponding channel information is obtained.
It is understood that because according to the division of frequency spectrum and service condition instantly, LTE frequency spectrum is very close to WLAN
2.4GHz portions of the spectrum, therefore when LTE is also operated in 2.4GHz portions of the spectrum, both inevitably exist dry
Disturb.
Therefore, when detecting mobile terminal and currently carrying out LTE speech businesses, obtain respectively current LET band informations with
And WLAN working frequency range information, so as to the working frequency range information according to LET band informations and WLAN, in mobile terminal active

Hz, then the frequency range spacing between them is 102MHz.
In step S205, judge whether the frequency range spacing is less than predetermined threshold value.
If the frequency range is smaller than predetermined threshold value, step S206 is directly performed；If the frequency range spacing is more than or waited
In predetermined threshold value, then step S209 is directly performed.
It is understood that the predetermined threshold value can be determined according to concrete scene, if scene requirement is more accurate,
The predetermined threshold value can set relatively small, if scene requirement is not high, and the predetermined threshold value can set relatively large, this
Place is not construed as limiting to its specific value.
In step S206, multiple default sub- threshold values are obtained, the frequency range spacing is entered with the multiple default sub- threshold value
Row compares, and obtains comparative result.
In step S207, corresponding default interference rank is determined according to the comparative result.
In step S208, based on the default interference rank, it is determined that needing destination channel and the scanning scanned.
In step S209, whole channels indicated in WLAN band information are scanned.
Can be specifically, such as, when LTE is in voice call, the presently used LTE frequency ranges of acquisition for mobile terminal be believed
Breath, if frequency range used in LTE and the spacing of WLAN 2.4GHz band limits are more than or equal to predetermined threshold value, WLAN is complete
Channel (CH1, CH2 ... CH13) be scanned.
Again such as, if band information used in LTE and WLAN 2.4GHz band limits are smaller than predetermined threshold value,
Then WLAN is by the way of local channel scanning.The low channel in B41 has been used such as LTE, to avoid interference, WLAN can be set
CH13, CH12, CH11 etc. can just exclude, be defined as interference channel.
It should be noted that, the quantity of specific interference channel can determine according to the degree of mutual interference, therefore it is determined that spacing is small
When predetermined threshold value, in addition it is also necessary to set many sub- threshold values to distinguish multiple ranks, the degree being disturbed is distinguished with this.It is described pre-
If threshold value can be as threshold value 1, being defined with this needs all channel scanning or local channel scanning, and many sub- threshold values respectively can be with
Threshold value 2, threshold value 3 ... are set to, wherein, threshold value 1>Threshold value 2>Threshold value 3 ....
That is, judging WLAN interference channels according to mutual interference, and interference channel is excluded, other channels is scanned,
To solve influence during available AP around mobile terminal WLAN active scans to user's communication, it is to avoid interference, user's body is lifted
Test.
In addition, when detecting mobile terminal and currently not carrying out LET speech businesses, it is believed that default voice calling service with
Interference is not present between WLAN, therefore, WLAN all channels can be scanned.
