When dynamic terminal does not currently carry out LTE speech business, directly perform step S209.
In step S202, determine the LET band information that LTE speech business is used.
In step S203, obtain the band information of WLAN and corresponding channel information.
It is understood that due to the division according to frequency spectrum instantly and service condition, the frequency spectrum of LTE is very close to WLAN
The portions of the spectrum of 2.4GHz, therefore when LTE is also operated in the portions of the spectrum of 2.4GHz, the most inevitably also exists dry
Disturb.
Therefore, when detecting that mobile terminal currently carries out LTE speech business, obtain respectively current LET band information with
And the working frequency range information of WLAN, in order to according to the working frequency range information of LET band information and WLAN, at mobile terminal actively

Hz, then the frequency range spacing between them is 102MHz.
In step S205, it is judged that whether described frequency range spacing is less than predetermined threshold value.
If described frequency range is smaller than predetermined threshold value, the most directly perform step S206；If described frequency range spacing more than or etc.
In predetermined threshold value, the most directly perform step S209.
It is understood that described predetermined threshold value can determine according to concrete scene, if scene requirement is more accurate, then
This predetermined threshold value can arrange relatively small, if scene requirement is the highest, then this predetermined threshold value can arrange relatively large, this
Its concrete value is not construed as limiting by place.
In step S206, obtain multiple default sub-threshold value, described frequency range spacing is entered with the plurality of default sub-threshold value
Row compares, and obtains comparative result.
In step S207, determine that corresponding presetting disturbs rank according to described comparative result.
In step S208, based on described default interference rank, determine and need the destination channel of scanning and scan.
In step S209, whole channels indicated in the band information of WLAN are scanned.
Can be concrete, such as, when LTE is in voice call, acquisition for mobile terminal presently used LTE frequency range is believed
Breath, if the spacing of the frequency range that used of LTE and WLAN 2.4GHz band limits is more than or equal to predetermined threshold value, then WLAN is entirely
Channel (CH1, CH2 ... CH13) is scanned.
The most such as, if the band information that used of LTE and WLAN 2.4GHz band limits be smaller than predetermined threshold value,
Then WLAN uses the mode of local channel scanning.Employ the low channel in B41 such as LTE, for avoiding interference, WLAN can be set
CH13, CH12, CH11 etc. just can get rid of, be defined as interference channel.
It should be noted that, the quantity of concrete interference channel can be determined according to the degree of mutual interference, is therefore determining that spacing is little
When predetermined threshold value, in addition it is also necessary to set many sub-threshold values to distinguish multiple rank, distinguish the degree being disturbed with this.Described pre-
If threshold value can define with this need all channel scanning or local channel scanning as threshold value 1, many sub-threshold values are the most permissible
It is set to threshold value 2, threshold value 3 ..., wherein, threshold value 1 > threshold value 2 > threshold value 3 ....
It is to say, judge WLAN interference channel according to mutual interference, and get rid of interference channel, other channels be scanned,
Impact on user's communication during to solve AP available around mobile terminal WLAN active scan, it is to avoid interference, promotes user's body
Test.
It addition, when detecting that mobile terminal does not currently carry out LET speech business, it is believed that preset voice calling service with
