Referring to Fig. 5, it is the second embodiment schematic flow sheet of the control method that coexists of the LTE that provides of the embodiment of the present invention and WiFi.The control method that LTE described in the present embodiment and WiFi coexist, comprises step:

S201, obtains the frequency information of LTE.

In the present embodiment specific implementation, can in the LTE of terminal equipment and the radio-frequency channel of WiFi, multiple filters be set in advance, the radio-frequency channel of LTE and WiFi is divided into multiple passages with different bandwidth, and wherein, the filter of setting can comprise bandwidth selection filter, full frequency band filter etc.Wherein, above-mentioned bandwidth selection filter, full frequency band filter are only all the filters of functional restriction, not specifically refer to some specific filter.Bandwidth filter described in the present embodiment, full frequency band filter are only for example; and it is non exhaustive; in specific implementation; also can comprise and can carry out the various filters of the same type of the functions such as bandwidth selection or Frequency Band Selection, as long as can realize in the scope that the filter of bandwidth selection, Frequency Band Selection all protects in the present invention.As shown in Figure 6, a bandwidth selection filter (sacrificing as shown in Figure 6 LTE bandwidth filter) and two kinds of filters of a full frequency band filter (LTE full frequency band filter as shown in Figure 6) can be set in advance in the radio-frequency channel of LTE, the LTE passage that is provided with bandwidth selection filter is divided into the LTE passage of LTE bandwidth loss, and the LTE passage that is provided with full frequency band filter is divided into LTE full frequency band passage.Concrete, can also in the radio-frequency channel of LTE, radio-frequency (RF) switch be set, select bandwidth selective filter or one of them filter of full frequency band filter by radio-frequency (RF) switch, thereby selection has the LTE passage of LTE bandwidth loss as the radio-frequency channel of current LTE, still selects the radio-frequency channel of LTE full frequency band passage as current LTE.In addition, as shown in Figure 6, a bandwidth selection filter (sacrificing as shown in Figure 6 WiFi bandwidth filter) and two kinds of filters of a full frequency band filter (WiFi full frequency band filter as shown in Figure 6) can also be set in advance in the radio-frequency channel of WiFi, the WiFi passage that is provided with bandwidth selection filter is divided into the WiFi passage of WiFi bandwidth loss, and the WiFi passage that is provided with full frequency band filter is divided into WiFi full frequency band passage, the WiFi passage of not placing filter can also be divided into without filtering channel.Concrete, the radio-frequency (RF) switch of a SP3T can also be set in the radio-frequency channel of WiFi, select bandwidth selective filter or one of them filter of full frequency band filter or selection there is no filter by radio-frequency (RF) switch, thereby selection has the WiFi passage of WiFi bandwidth loss as the radio-frequency channel of current WiFi, or select the radio-frequency channel of WiFi full frequency band passage as current WiFi, or the WiFi of reactive filter without filtering channel the radio-frequency channel as current WiFi.Terminal equipment is divided into the radio-frequency channel of LTE in passage and the LTE full frequency band passage of LTE bandwidth loss, and the radio-frequency channel of WiFi is divided into passage and the WiFi full frequency band passage of the loss of WiFi bandwidth, and the WiFi that filter is not set is without after filtering channel, can decide which LTE passage of concrete selection as current LTE radio-frequency channel or select which WiFi passage as current WiFi radio-frequency channel according to the LTE frequency information getting.

In some feasible execution modes, terminal equipment can first obtain LTE network signal from base station, and judges according to the network signal getting whether LTE network exists coexistence problems with WiFi network.Concrete, in the LTE network signal that terminal equipment obtains from base station, can comprise the LTE such as band information, the frequency point information frequency information of LTE.Terminal equipment gets after the frequency information of LTE the difference that can judge the frequency of LTE and the frequency range of WiFi according to the frequency information of the WiFi prestoring whether within the scope of default frequency-splitting, and does the selection of LTE radio-frequency channel and WiFi radio-frequency channel according to judged result.

S202, judges whether described LTE frequency range is risk frequency range, if judged result is no, performs step S203, if the determination result is YES, performs step S204.

S203, selects not arrange the radio-frequency channel that the WiFi channel setting of filter is described WiFi.

S204, whether the difference that judges described LTE frequency and described WiFi frequency in default frequency difference range, if the determination result is YES, performs step S205, if judged result is no, performs step S206.

S205, the radio-frequency channel that the WiFi channel setting of selecting to have WiFi bandwidth loss is described WiFi, and select the radio-frequency channel that the full frequency band channel setting of described LTE is described LTE.

S206, the radio-frequency channel that the LTE channel setting of selecting to have LTE bandwidth loss is described LTE, and select the radio-frequency channel that the full frequency band channel setting of described WiFi is described WiFi.

In some feasible execution modes, can be in advance by experiment or other modes judge in LTE frequency range, which frequency range may exist mutual interference problem with WiFi, can prejudge which frequency range and WiFi and have mutual interference risk, and to specify these frequency ranges be risk frequency range, be pre-stored in terminal equipment.Terminal equipment gets after LTE network signal, the LTE band information that can comprise according to the LTE network signal getting judges whether the frequency range of LTE is risk frequency range, whether the LTE frequency range that can judge the LTE signal getting is in those several risk frequency ranges of specifying, thereby can judge whether to exist the coexistence problems of LTE and WiFi.Wherein, the frequency of WiFi is the information being pre-stored in terminal equipment, and the frequency of WiFi is frequency values known to public, fixing.If terminal equipment learns that according to the LTE frequency range judgement in the frequency information of the LTE getting the frequency range of LTE is not risk frequency range (being that LTE frequency range is not in those several risk frequency ranges of specifying), can judge and learn that LTE network and WiFi network do not have coexistence problems.If judgement learns that now LTE network and WiFi network do not have coexistence problems, the WiFi that can the radio-frequency (RF) switch by WiFi radio-frequency channel selects not arrange filter is the radio-frequency channel as current WiFi without filtering channel, to reduce the loss on WiFi passage, promote covering and the handling capacity of WiFi, strengthen user's experience effect of terminal equipment.

If terminal equipment judges and learns that the frequency range of LTE is risk frequency range according to the LTE frequency range in the LTE frequency information getting, may there is coexistence problems in LTE network and WiFi network now, when LTE network and the work of WiFi network, may interfere with each other the other side's radio-frequency performance, whether the difference that can further judge the frequency of LTE and the frequency of WiFi according to the frequency of LTE is in default frequency difference range.If terminal equipment judges that according to the frequency of the frequency of LTE and WiFi the difference of learning the frequency of LTE and the frequency of WiFi is in default frequency difference range, can judge and learn that now LTE network and WiFi network exist coexistence problems, when LTE network and the work of WiFi network, can interfere with each other the other side's RF capabilities.Because the LTE network now getting is the frequency spectrum resource that operator has, in order to ensure that operator can normally be used this terminal equipment, be that terminal equipment can normally use LTE network can use again WiFi network simultaneously, can select the WiFi channel setting of WiFi bandwidth loss is current WiFi radio-frequency channel, and select the radio-frequency channel that LTE full frequency band channel setting is current LTE, to ensure that LTE and WiFi can coexist and not interfere with each other the other side's radio-frequency performance, the restriction of the frequency spectrum resource that guarantee terminal equipment Bu Shou operator has.Concrete, can select bandwidth selective filter by the radio-frequency (RF) switch on WiFi passage, thereby select to have the WiFi passage (as shown in Figure 6 with the WiFi passage of sacrificing WiFi bandwidth filter) of WiFi bandwidth loss as the radio-frequency channel of current WiFi, and select full frequency band filter by the radio-frequency (RF) switch on LTE passage, thereby select the full frequency band passage (the LTE passage with LTE full frequency band filter as shown in Figure 6) of LTE as the radio-frequency channel of current LTE.

If terminal equipment judges that according to the frequency of the LTE in the LTE frequency information getting the difference of learning the frequency of LTE and the frequency of WiFi is not in default frequency difference range, can judge the LTE network learnt now and the work of WiFi network time, can not interfere with each other the other side's radio-frequency performance, the frequency range that in the LTE network getting, some frequency is corresponding is not used.Now, in order to ensure the available channel of WiFi, ensure better the radio-frequency performance of LTE and WiFi, the radio-frequency channel that can be current LTE by the LTE channel setting that has the loss of LTE bandwidth, and the radio-frequency channel that is current WiFi by the full frequency band channel setting of WiFi, to ensure that LTE and WiFi can coexist and not interfere with each other the other side's radio-frequency performance, improve user's experience effect of terminal equipment.Concrete, can select bandwidth selective filter by the radio-frequency (RF) switch on LTE passage, thereby select to have the LTE passage (as shown in Figure 6 with the LTE passage of sacrificing LTE bandwidth filter) of LTE bandwidth loss as the radio-frequency channel of current LTE, and select full frequency band filter by the radio-frequency (RF) switch on WiFi passage, thereby select the full frequency band passage (the WiFi passage with WiFi full frequency band filter as shown in Figure 6) of WiFi as the radio-frequency channel of current WiFi.

The present embodiment can judge whether LTE frequency range is risk frequency range according to the frequency information of the LTE getting, judge that with this LTE and WiFi possibility exist coexistence problems, judge according to the difference of the frequency of the frequency of LTE and WiFi whether LTE and WiFi exist coexistence problems again, whether can interfere with each other the other side's RF capabilities, and select the radio-frequency channel of LTE and the radio-frequency channel of WiFi according to judged result, can select to sacrifice the bandwidth of LTE or the bandwidth of sacrificing WiFi, the restriction of the frequency spectrum resource that when LTE and WiFi are coexisted, terminal equipment Bu Shou operator has, also can use more WiFi available channel, improve the network performance of terminal equipment, strengthen user's experience effect of terminal equipment, promote user's stickiness of terminal equipment.
