Whether identify this vibration signal is that user knocks the vibration signal that this mobile terminal produces;
If so, extract this vibration signal.
Wherein, vibration signal is that this mobile terminal is subject to External Force Acting to send the sound wave of generation of vibration correspondingThe signal of telecommunication (such as, data signal or analog electrical signal). For example, when user knocks mobile terminal, moveMoving terminal can be vibrated, thereby terminal can produce acoustic signals, and the signal of telecommunication that this acoustic signals is corresponding isThe vibration signal that user produces by knocking mobile terminal.
In the present embodiment, gather can have for the mode of the vibration signal of mobile terminal multiple, such as canWith the microphone by mobile terminal, loudspeaker or receiver obtain user knock mobile terminal produceVibration signal, because microphone, loudspeaker or receiver are with acoustic-electric converter, is subject at mobile terminalWhile knocking generation vibration to user, microphone or loudspeaker can be responded to the acoustic signals of mobile terminal, and shouldAcoustic signals is converted into into the corresponding signal of telecommunication, i.e. vibration signal, thus it is eventually mobile by knocking to obtain userThe vibration signal that end produces.

102, obtain corresponding network handover request according to this vibration signal, this network handover request instruction needsThe objective network being switched to.
Such as, mobile terminal can obtain corresponding network handover request according to vibration signal, and this network switchesThe mobile data network that request instruction need to be switched to, or be switched to another WLAN etc. Network is cutThe request of changing can be carried the mark of the objective network that need to be switched to, and for example, carries the mark of target wifi etc.
Particularly, the mode of obtaining corresponding network handover request according to vibration signal has multiple, such as, canTo determine whether mobile terminal exists the vibration signal mating with this vibration signal, if exist, obtain coupling and shakeMoving network handover request corresponding to signal is also that " obtain corresponding network according to this vibration signal switches stepRequest " can comprise: determine in default sample set whether have the sample mating with this vibration signal, ifExist, obtain the network handover request that matched sample is corresponding; Particularly, can obtain the letter of vibration signalWhether number characteristic information (time, frequency, amplitude), then, determine in default sample set and exist and thisThe sample of signal characteristic information coupling, if exist, determines in this default sample set and exists and this vibration letterThe sample of number coupling, if do not exist, determines in this default sample set and does not exist with this vibration signal and mateSample. Wherein, in this default sample set, can comprise at least one sample of signal, be called for short sample, everyKind of sample can corresponding a kind of network handover request, such as, every kind of different objective network of the corresponding instruction of sampleNetwork handover request etc., sample 1 map network handover request 1, this request instruction need to be switched to WLAN1,Sample 2 map network handover request 2, this request instruction need to be switched to WLAN2, and sample 3 map networks are cutThe request of changing 3, this request instruction need to be switched to mobile data network ...
For example, can determine the frequency spectrum of vibration signal, the time to this frequency spectrum, frequency and amplitude are carried out respectivelyAnalyze, obtain analysis result, determine in default sample set whether have the sample mating with this analysis result,If exist, determine the sample that in this default sample set, existence is mated with this vibration signal; If do not exist,Determine in this default sample set and do not have the sample mating with this vibration signal.
Again such as, can obtain corresponding number of taps according to vibration signal, then, judge number of taps withPreset times compares, if identical, obtains network handover request corresponding to preset times; Also be step" obtaining corresponding network handover request according to this vibration signal " can comprise:
The number of taps of obtaining user and knocking this mobile terminal according to this vibration signal;
Judge that whether this number of taps is identical with preset times, if so, obtains net corresponding to this preset timesNetwork handover request.
The preset times set that comprises at least one preset times can be set in actual applications, every kind of number of timesCorresponding a kind of network handover request, the objective network of each network handover request instruction is not identical, such as, number of times1 map network handover request 1, this request instruction need to be switched to WLAN1, and number of times 2 map networks switch pleaseAsk 2, this request instruction need to be switched to WLAN2, number of times 3 map network handover request 3, this request instructionNeed to be switched to mobile data network ...
For example, user is continuous while knocking mobile terminal three times, the vibration signal that acquisition for mobile terminal is corresponding, andWhether be vibration signal that user by knock mobile terminal produced, if so, move if identifying this vibration signalMoving terminal is analyzed this vibration signal, and obtains active user according to analysis result and knock this mobile terminalNumber of taps, here for number of taps is 3, suppose that preset times is for being also at 3 o'clock, the number of taps of obtainingIdentical with preset times, now, obtain network handover request corresponding to preset times, and according to this networkThe network of current connection is switched to this objective network by handover request, supposes that preset times is at 4 o'clock, so,Number of taps is not identical with preset times, now, does not carry out network switching, has avoided mobile terminal that mistake occursOperation. Particularly, preset times can be set according to actual conditions, such as arrange number of taps be 5,Just trigger network switching etc. 6 or 7 times time.
The number of taps that the present embodiment can obtain user and knocks mobile terminal vibration signal analysis,Such as, obtain the frequency spectrum of vibration signal, time and amplitude to frequency are analyzed, and come according to analysis resultObtain corresponding number of taps.
103, according to this network handover request, the network of current connection is switched to this objective network.
Wherein, the mode that the network of current connection is switched to objective network according to network request has multiple, cutsThe mode of changing can be based on current connection network and the type decided of objective network.
Such as, the network of the current connection of mobile terminal is WLAN, when objective network is mobile data network,Now, mobile terminal will be closed WLAN, and opens mobile data network, switches to complete network.
Again such as, when the network of the current connection of mobile terminal is mobile data network, objective network is WLANTime, now, because general WLAN priority is higher than mobile data network, therefore, mobile terminal can be beatenOpen WLAN, can complete network and switch, alternatively, mobile terminal can also be opened WLAN, closes and movesMoving data network, saves electric weight; Particularly, mobile terminal can be according to network handover request to WLANCorresponding access device sends network connecting request, the network identity that this network connecting request is carried WLAN withAnd connect authentication information (such as, wifi password), receive that this access device returns according to network connecting requestResponse message, and be connected to this WLAN according to this response message.
Again such as, the network of the current connection of mobile terminal is WLAN1, when objective network is WLAN2, movesMoving terminal can send network connecting request to access device corresponding to WLAN2 according to network handover request,This network connecting request is carried the network identity of WLAN2 and is connected authentication information (such as, wifi password),Receive the response message that this access device returns according to network connecting request, be connected to this according to this response messageWLAN2, and being connected of disconnection and WLAN1.
Consider the time interval of user's hammer action, moving with knocking of non-user (such as robot etc.)The time interval of doing is not identical, and in fact, user's hammer action is not very fast, alternatively, shakes for improvingThe identification accuracy of moving signal, judge key feature information meet pre-conditioned after, also need knockingMove the corresponding time and analyze; Particularly, judge key feature information meet pre-conditioned after,This call handover method can also comprise:
Obtain the adjacent time interval of knocking this mobile terminal for twice according to this vibration signal;
Judge that this time interval whether in preset range, if so, judges that this vibration signal passes through as userKnock the vibration signal that this mobile terminal produces, if not, judge this vibration signal not as user by knockingThe vibration signal that this mobile terminal produces.
Due to the time interval of user's hammer action, can in the temporal information of vibration data signal, embody,Therefore, can to vibration data signal carry out time series analysis, obtain adjacent knock for twice this mobile terminal timeBetween interval, then, judge that whether this time interval is in preset range; In actual applications, can arrange oneIndividual time range [T3, T4], preferably, T3 is 50ms, T4 is 500ms, if not within the scope of this,This shows that this vibration signal is not that people knocks the vibration signal that mobile terminal produces.
Alternatively, in the present embodiment, vibration signal can be for user be by knocking shaking of mobile terminal screen generationMoving signal, now, can be limited in specific beating position and knock mobile terminal and just can switch by trigger network, canTo prevent that maloperation network from switching; The screen area that knocks network connection icon place such as, user is just passableTrigger network switches; Also,, between step 101 and step 102, this method for switching network can also comprise:
Obtain the beating position that user knocks mobile terminal screen;
Judge whether this beating position is positioned at predeterminable area, the network that this predeterminable area is current network connectsThe screen area at icon place;
If so, carry out the step of obtaining corresponding network handover request according to this vibration signal.
Wherein, the mode of obtaining beating position has multiple, knocks such as responding to user by touch screenBeating position etc.
Alternatively, be user when knocking the vibration signal that mobile terminal screen produces at vibration signal, thisEmbodiment is user by after knocking the vibration signal that mobile terminal produces at this vibration signal of identification, also needsIdentify beating position that user knocks mobile terminal whether on the screen of mobile terminal.
For example, when user knocks wifi network connection icon, acquisition for mobile terminal user knocks wifi network and connectsThe vibration signal that map interlinking mark produces and the beating position on screen; Mobile terminal judges that this beating position isNo is the position at wifi network connection icon place, if so, mobile terminal obtain according to this vibration signal rightThe network handover request of answering, and carry out network switching according to this request.
As from the foregoing, the embodiment of the present invention adopts and obtains the vibration letter that user produces by knocking this mobile terminalNumber, then, obtain corresponding network handover request according to this vibration signal, this network handover request instruction needsThe objective network being switched to, switches to this target network according to this network handover request by the network of current connectionNetwork; This scheme can be knocked the vibration signal automatically switching network that mobile terminal produces by user, without useA series of network handover operation is carried out for terminal in family, for user, only need knock mobile terminalRealize network and switch, in terms of existing technologies, improved the network switching efficiency of mobile terminal, and thenPromote user's experience.
