Inmobile terminal 100 first embodiment of the present invention, referring to Fig. 1,mobile terminal 100 comprises light sensor 121, application scenario determining unit 130 and the state switch unit 140 of preposition light sensor 111, postposition, and application scenario determining unit 130 is connected with preposition light sensor 111, rearmounted light sensor 121 and state switch unit 140 respectively.

Wherein, preposition light sensor 111 is arranged at the front ofmobile terminal 100, and screen one side, as shown in Figure 2, can be arranged at the top of screen, and it is for detecting in real time the intensity I of the ambient light inmobile terminal 100 fronts₁, and by the I detecting₁with default first threshold comparison, if I₁be less than or equal to first threshold, preposition light sensor 111 produces and sends interrupt signal.

Rearmounted light sensor 121 is arranged at the back side ofmobile terminal 100, be the back side ofmobile terminal 100 screens, rearmounted light sensor 121 can be arranged on the top atmobile terminal 100 back sides or below to avoid the middle part ofmobile terminal 100, avoid user to hold the impact ofmobile terminal 100, as shown in Figure 3, rearmounted light sensor 121 can be arranged to the side (being the top atmobile terminal 100 back sides) ofmobile terminal 100 back side cameras.Rearmounted light sensor 121 is for detecting in real time the intensity I of the ambient light atmobile terminal 100 back sides₂, and by the I detecting₂with the 3rd default threshold value comparison, at I₂while being less than or equal to the 3rd threshold value, rearmounted light sensor 121 produces and sends interrupt signal.

Application scenario determining unit 130, for based on I₁and I₂testing result determine the residing application scenario of mobile terminal.Particularly, the interrupt signal variable that 111 generations of preposition light sensor are set is INT_FRONT, the interrupt signal variable that 121 generations of rearmounted light sensor are set is INT_BACK, if application scenario determining unit 130 receives the interrupt signal that preposition light sensor 111 sends, INT_FRONT is 1, if do not receive the interrupt signal that preposition light sensor 111 sends, INT_FRONT is 0.If application scenario determining unit 130 receives the interrupt signal that rearmounted light sensor 121 sends, INT_BACK is 1, if do not receive the interrupt signal that rearmounted light sensor 121 sends, INT_BACK is 0.The logic state of INT_FRONT and INT_BACK and the corresponding relation of application scenario are as shown in table 1.

Table 1

Application scenario	INT_FRONT	INT_BACK
			Thefirst application scenario	0	0
Thesecond application scenario	1	0
			The3rd application scenario	0	1
The4th application scenario	1	1

In the present embodiment, referring to table 1, work as I₁be greater than first threshold, and L₂while being greater than the 4th threshold value, application scenario determining unit 130 determines thatmobile terminal 100 is in the first application scenario; Work as I₁be less than or equal to first threshold, and I₂while being greater than the 3rd threshold value, application scenario determining unit 130 determines thatmobile terminal 100 is in the second application scenario; Work as I₁be greater than first threshold, and I₂while being less than or equal to Second Threshold, application scenario determining unit 130 determines thatmobile terminal 100 is in the 3rd application scenario; Work as I₁be less than or equal to first threshold, and I₂while being less than or equal to the 3rd threshold value, application scenario determining unit 130 determines thatmobile terminal 100 is in the 4th application scenario.

Under the first application scenario, preposition light sensor 111 and rearmounted light sensor 121 all produce without interrupt signal, nowmobile terminal 100 is in use state, under use state,mobile terminal 100 receives the operation (for example, user's point touching shields, and function button is triggered) that user carries out, and/or there is the application program (for example, game, video jukebox software, document ocr software etc.) of non-running background to move.

Under the second application scenario, preposition light sensor 111 produces interrupt signal, rearmounted light sensor 121 produces without interrupt signal, now the front ofmobile terminal 100 is blocked, in idle or talking state, for examplemobile terminal 100 face down are positioned over desktop, whenmobile terminal 100 is mobile phone, user makes a phone call by mobile phone, the mobile phone face of being close to the users.

Under the 4th application scenario, preposition light sensor 111 and rearmounted light sensor 121 all produce interrupt signal, and nowmobile terminal 100 front and backs are all blocked, and for example,mobile terminal 100 is placed on Bao Baoli.

State switch unit 140, based on the residing application scenario of the determinedmobile terminal 100 of application scenario determining unit 130, makesmobile terminal 100 be switched to use state or puts out screen holding state.Particularly, whenmobile terminal 100 is during in the first application scenario, whethermobile terminal 100 puts out screen standby depends on default very first time interval, very first time interval can be automatic stand-by time T, state switch unit 140 is switched to use state (switching herein also can be understood as and allowsmobile terminal 100 maintain use state) bymobile terminal 100, and further judgemobile terminal 100 stops using the time of (if mobile terminal does not receive operational order or do not exist the application program operation of non-running background to judge thatmobile terminal 100 stops using) whether to be more than or equal to very first time interval, ifmobile terminal 100 is switched to and puts out screen holding state, maintain if not the current state of mobile terminal 100.Whenmobile terminal 100 is during in the second application scenario, state switch unit 140 is switched to mobile terminal and puts out screen holding state immediately, andmobile terminal 100 puts out screen standby screen locking (if user is provided with screen locking function) immediately.Whenmobile terminal 100 is during in the 3rd application scenario, state switch unit 140 first judges thatmobile terminal 100 is current whether in use state, if maintain the current state of mobile terminal, represent that if notmobile terminal 100 is current for idle,mobile terminal 100 is switched to and puts out screen holding state,mobile terminal 100 puts out screen standby screen locking (if user is provided with screen locking function) immediately. whenmobile terminal 100 is during in the 4th application scenario, state switch unit 140 is switched tomobile terminal 100 to put out screen holding state,mobile terminal 100 puts out screen standby screen locking (if user is provided with screen locking function) immediately.

In mobile terminal 100 second embodiment of the present invention, shown in Figure 1, in this enforcement, mobile terminal 100 comprises preposition light sensor 111 and range sensor 112, rearmounted light sensor 121 and range sensor 122, application scenario determining unit 130 and state switch unit 140, and application scenario determining unit 130 is connected with range sensor 120 and state switch unit 140 with preposition light and range sensor 110, rearmounted light respectively.Wherein, preposition light sensor 111 and range sensor 112 are arranged at the front of mobile terminal 100, i.e. screen one side, as shown in Figure 2, can be arranged at the top of screen, preposition light sensor 111 is for detecting in real time the intensity I of the ambient light in mobile terminal 100 fronts₁, and by the I detecting₁with default first threshold comparison, and at I₁while being less than or equal to first threshold, produce and send interrupt signal, preposition range sensor 112 is for detecting in real time the distance L in shelter and mobile terminal 100 fronts₁, and by the L detecting₁compare with default Second Threshold, if L₁while being less than or equal to Second Threshold, preposition range sensor 112 produces and sends interrupt signal.Mobile terminal 100 be take mobile phone as example, if user makes a phone call by mobile phone, user's face is close to the front of mobile phone, and preposition light sensor 111 detects the intensity I of the ambient light in mobile phone front₁be less than or equal to first threshold, preposition range sensor 111 detects the distance L in shelter (user's face) and mobile phone front₁be less than or equal to Second Threshold, all produce and send interrupt signal.

The back side that rearmounted light sensor 121 and range sensor 122 are arranged atmobile terminal 100, be the back side ofmobile terminal 100 screens, the top that rearmounted light sensor 121 and range sensor 122 can be arranged onmobile terminal 100 or below are to avoid the middle part ofmobile terminal 100, avoid user to hold the impact ofmobile terminal 100, as shown in Figure 3, rearmounted light sensor 121 and range sensor 122 can be arranged to the side ofmobile terminal 100 back side cameras.Rearmounted light sensor 121 is for detecting in real time the intensity I of the ambient light atmobile terminal 100 back sides₂, and by the I detecting₂with the 3rd default threshold value comparison, if I₂be less than or equal to the 3rd threshold value, produce and send interrupt signal.Rearmounted range sensor 122 is for detecting in real time the distance L at shelter and the mobile terminal back side₂, and by the L detecting₂with the 4th default threshold value comparison, and at L₂while being less than or equal to the 4th threshold value, produce and send interrupt signal.

Application scenario determining unit 130, determines the residing application scenario of mobile terminal for the testing result based on I1 and L1, I2 and L2.The interrupt signal variable that preposition light sensor 111 and range sensor 112 generations are set is INT_FRONT, and the interrupt signal variable that rearmounted light sensor 121 and range sensor 122 generations are set is INT_BACK.Work as L₁while being less than or equal to Second Threshold, will inevitably cause I₁from being greater than light intensity threshold value, dropping to and be less than or equal to first threshold, and I₁from being greater than first threshold, dropping to while being less than or equal to first threshold and not necessarily have shelter to be positioned at mobile terminal 100 fronts, for example, mobile terminal 100 is in a darkroom.Therefore, the interrupt signal that application scenario determining unit 130 produces preposition light sensor 111 and range sensor 112 separately carries out, after logical AND processing, obtaining the value of variable INT_FRONT, in like manner obtains the value of variable INT_BACK.For example, preposition light sensor 111 and range sensor 112 all do not produce interrupt signal, and the value of variable INT_FRONT is 0; If preposition light sensor 111 produces interrupt signal, range sensor 112 does not produce interrupt signal, and the value of variable INT_FRONT is 0; When preposition range sensor 112 produces interrupt signal, preposition light sensor 111 must produce interrupt signal, and the value of variable INT_FRONT is 1.In like manner, rearmounted light sensor 121 and range sensor 122 all do not produce interrupt signal, and the value of variable INT_BACK is 0; If rearmounted light sensor 121 produces interrupt signal, range sensor 122 does not produce interrupt signal, and the value of variable INT_BACK is 0; When rearmounted range sensor 122 produces interrupt signal, rearmounted light sensor 121 must produce interrupt signal, and the value of variable INT_BACK is 1.

In other embodiment ofmobile terminal 100 of the present invention abovemobile terminal 100 back sides and below light sensor 121 and/or the range sensor 122 of difference postposition, by being arranged at rearmounted light sensor 121 and/or the range sensor 122 of lower rear, identify better the situation of holding mobile phone.Application scenario determining unit 130 can be by the light sensor 121(range sensor 122 of a plurality of postposition) interrupt signal that produces carries out logic OR processing and participates in follow-up judgement and processing again.

The logic state of INT_FRONT and INT_BACK and the corresponding relation of application scenario are as shown in table 1.Visible, in the present embodiment, work as L₁be greater than first threshold, and L₂while being greater than the 4th threshold value, application scenario determining unit 130 determines thatmobile terminal 100 is in the first application scenario; Work as I₁and L₁all be less than or equal to each self-corresponding threshold value, and L₂while being greater than the 4th threshold value, application scenario determining unit 130 determines thatmobile terminal 100 is in the second application scenario; Work as L₁be greater than Second Threshold, and I₂and L₂while being all less than or equal to each self-corresponding threshold value, application scenario determining unit 130 determines thatmobile terminal 100 is in the 3rd application scenario; Work as I₁and L₁all be less than or equal to each self-corresponding threshold value, and I₂and L₂while being all less than or equal to each self-corresponding threshold value, application scenario determining unit 130 determines thatmobile terminal 100 is in the 4th application scenario.

Under the first application scenario,mobile terminal 100 is in use state, under use state, mobile terminal 100 (for example receives operation that user carries out, user's point touching screen, function button is triggered), and/or have the application program (for example, game, video jukebox software, document ocr software etc.) of non-running background to move.

Under the second application scenario, the front ofmobile terminal 100 thing that is blocked blocks, and in idle or talking state, for examplemobile terminal 100 face down are positioned over desktop, and whenmobile terminal 100 is mobile phone, user makes a phone call by mobile phone, the mobile phone face of being close to the users.

Under the 3rd application scenario, the back side ofmobile terminal 100 thing that is blocked blocks, in idle or use state, for examplemobile terminal 100 faces up and leaves unused in desktop, ormobile terminal 100 faces up and is positioned over the application program (use state) that desktop and user are just just moving non-running background on operatingmobile terminal 100 ormobile terminal 100.

Under the 4th application scenario,mobile terminal 100 front and backs are all blocked by obstructions, and for example,mobile terminal 100 is placed on Bao Baoli.

State switch unit 140, based on the residing application scenario of the determined mobile terminal 100 of application scenario determining unit 130, makes mobile terminal 100 be switched to use state or puts out screen holding state.Particularly, when mobile terminal 100 is during in the first application scenario, whether mobile terminal 100 puts out screen standby depends on default very first time interval, very first time interval can be automatic stand-by time T, state switch unit 140 is switched to use state (switching herein also can be understood as and allows mobile terminal 100 maintain use state) by mobile terminal 100, and further judge mobile terminal 100 stops using the time of (if mobile terminal does not receive operational order or do not exist the application program operation of non-running background to judge that mobile terminal 100 stops using) whether to be more than or equal to very first time interval, if mobile terminal 100 is switched to and puts out screen holding state, maintain if not the current state of mobile terminal 100.When mobile terminal 100 is during in the second application scenario, state switch unit 140 is switched to mobile terminal and puts out screen holding state immediately, and mobile terminal 100 puts out screen standby screen locking (if user is provided with screen locking function) immediately.When mobile terminal 100 is during in the 3rd application scenario, state switch unit 140 first judges that mobile terminal 100 is current whether in use state, if maintain the current state of mobile terminal, represent that if not mobile terminal 100 is current for idle, mobile terminal 100 is switched to and puts out screen holding state, mobile terminal 100 puts out screen standby screen locking (if user is provided with screen locking function) immediately. whenmobile terminal 100 is during in the 4th application scenario, state switch unit 140 is switched tomobile terminal 100 to put out screen holding state,mobile terminal 100 puts out screen standby screen locking (if user is provided with screen locking function) immediately.
