This application claims priority to Chinese Patent Application No. 201210045673.X, filed on Feb. 25, 2012, which is hereby incorporated by reference in its entirety.
FIELD OF THE INVENTION
The present invention relates to the field of communication technologies, and in particular, to a sleep method, a wake method and a mobile terminal device.
BACKGROUND OF THE INVENTION
As a mobile terminal device, such as a smart mobile phone and a tablet computer, is more and more popular among vast users, more and more attention is also paid by users to the user experience for the use time length of this type of mobile terminal device.
In the prior art, the touch screen of the mobile terminal device consumes a very large part of energy, so when a user does not need to use the mobile terminal device, the user turns off the touch screen of the mobile terminal device usually by using a standby function, so that the mobile terminal device is in an off-screen standby state; when the user needs to use the mobile terminal device, the user then enables the touch screen of the mobile terminal device in a standby state to begin to normally work through a wake function, to save the power consumption of the mobile terminal device and achieve the objective of prolonging the use time of the mobile terminal device.
However, in the standby solution in the prior art, when a mobile terminal device is in a standby state, although the touch screen of the mobile terminal device is turned off, the mobile terminal device is still in the working state and still consumes the energy of the mobile terminal device to a very large extent, so the prolonging of the use time of the mobile terminal device in high efficiency cannot be achieved.
To overcome the defect, the user may solve the problem through a method in which the mobile terminal device is turned off through a temporary power-off manner, and when the user needs to use the mobile terminal device, the user then enables the mobile terminal device to begin to normally work through startup again. However, in the startup procedure of the mobile terminal device, only after the system is initialized and various system programs are loaded, the mobile terminal device can gradually enter the system, but this startup procedure is very long. If the user urgently needs to use the mobile terminal device, while the startup procedure in the prior art makes the user wait for a very long time, the user experience of the user for the mobile terminal device is influenced, thereby deteriorating the user experience.

The mobile terminal device provides a selection box for selecting to enter the sleep mode in a system setting interface, so as to be selected by the user.
When the mobile terminal device detects that a user presses a power key on the mobile terminal device manually for a long time, whether the selection box of the sleep mode in the system setting interface is selected is determined.
If it is determined that the selection box of the sleep mode in the system setting interface is selected, that is, it is determined that the user selects the sleep mode, the mobile terminal device begins step S 10 .
If it is determined that the selection box of the sleep mode in the system setting interface is not selected, that is, it is determined that the user does not select the sleep mode, the mobile terminal device executes a normal power-off procedure, that is, it is powered off.
Alternatively, when it is determined that the selection box of the sleep mode in the system setting interface is not selected, the mobile terminal device may further prompt whether the user selects to enter a sleep mode or enter a power-off mode through a selection box.
Second case: when whether to select sleep of the mobile terminal device is determined in an automatic system selection manner, the following may be included.
When the mobile terminal device detects that a user selects power-off, the mobile terminal device detects whether the mobile terminal device is currently in a charging state, or whether a high definition multimedia interface (High Definition Multimedia Interface, HDMI) is inserted with an HDMI line.

Definitely, when the power interface and the USB interface on the mobile terminal device are the same, and when the mobile terminal device detects that the event that the USB interface is inserted with a USB line occurs, the mobile terminal device performs a normal power-off procedure.
Step S 12 : according to the recorded service state information related to the data connection, turn off a service that is related to the data connection and is in a turn-on state. In this embodiment, the turning off the service that is related to the data connection and is turned on includes turning on an offline mode and turning off GPS.
Step S 14 : control a processor to enter a sleep mode. In this embodiment, when the processor is controlled to enter the sleep mode, the processor does not process communication and application services again. In this embodiment, the processor may be controlled to enter the sleep mode by setting the current running state of the processor to a sleep state.
In this embodiment, the processor may include multiple models of processors, such as a single-core processor, a dual-core processor, and a quad-core processor. In this embodiment, when the processor is a single-core processor, because a communication service and an application service are processed by one processor, the single-core processor is directly controlled to enter the sleep mode; when the processor is a dual-core processor, it is required to control a processor for processing a communication service and a processor for processing an application service to enter the sleep mode; when the processor is a quad-core processor, it is required to control a processor for processing a communication service and a processor for processing an application service to enter the sleep mode. The rest may be deduced by analogy. When the processor is a multi-core processor, it is required to control a processor for processing a communication service and a processor for processing an application service to enter the sleep mode.
In this embodiment, after the application service of the processor enters the sleep mode, the mobile terminal device turns off its screen, that is, it indicates that the mobile terminal device has entered the sleep mode.

Compared with the prior art, more services and apparatuses consuming energy are turned off, and the power consumption of the mobile terminal device is saved more than that in the prior art, so the use time of the mobile terminal device is prolonged more, and a user does not need to select a power-off manner to save the power consumption of the mobile terminal device.
In this embodiment, alternatively, on the basis of Embodiment 1, an additional operation may be added optionally. For example, when it is determined to select sleep of the mobile terminal device, a sleep effect through an animation or a wait box is displayed on the display screen of the mobile terminal device, or a sleep progress is prompted through a sound. Definitely, the operation may be performed together with other steps simultaneously. In this embodiment, the user is prompted in a manner that a sleep effect is displayed through an animation or a wait box on the display screen of the mobile terminal device or a sleep progress is prompted through a sound, so as to achieve improvement of user experience.
Alternatively, after the service that is related to the data connection and is in a turn-on state is turned off, a non-core process may be killed or turned off. In this embodiment, core processes include a core process, a phone process, a SYSTEM_UID process, and an android.process.media process.

Step S 42 : when determining to select sleep of the mobile terminal device, display a sleep effect in a manner of an animation or a wait box on a display screen of the mobile terminal device, or prompt a sleep progress in a sound manner.
While step S 42 is being executed, the following steps may be synchronously executed.
Step S 44 : when it is determined to select sleep of a mobile terminal device, the mobile terminal device records service state information related to data connection. In this embodiment, the service related to the data connection includes GPS, WIFI, and Bluetooth. In this embodiment, when the mobile terminal device is normally used, the service may have a current use state, so when the mobile terminal device enters sleep, the mobile terminal device records information of a current use state of the service, and the recorded state information is to be subsequently used to wake the mobile terminal device.
Step S 46 : turn off the service that is related to the data connection and is in a turn-on state. In this embodiment, the turning off the service that is related to the data connection and is turned on includes turning on an offline mode and turning off GPS.
Step S 48 : kill or turn off a non-core process. In this embodiment, core processes include a core process, a phone process, a SYSTEM_UID process, and an android.process.media process. In this embodiment, killing or turning off a non-core process refers to killing or turning off a process except the core processes.
Step S 49 : control a processor to enter a sleep mode. In this embodiment, when the processor is controlled to enter the sleep mode, the processor does not process communication and application services again. In this embodiment, the processor may be controlled to enter the sleep mode by setting the current running state of the processor to a sleep state.
In this embodiment, the processor may include multiple models of processors, such as a single-core processor, a dual-core processor, and a quad-core processor. In this embodiment, when the processor is a single-core processor, because a communication service and an application service are processed by one processor, the single-core processor is directly controlled to enter the sleep mode; when the processor is a dual-core processor, it is required to control a processor for processing a communication service and a processor for processing an application service to enter the sleep mode; when the processor is a quad-core processor, it is required to control a processor for processing a communication service and a processor for processing an application service to enter the sleep mode. The rest may be deduced by analogy. When the processor is a multi-core processor, it is required to control a processor for processing a communication service and a processor for processing an application service to enter the sleep mode.
After the processor enters the sleep mode, step S 42 may end, so as to indicate that the mobile terminal device has entered the sleep mode currently.
In the sleep method provided in the embodiment of the present invention, by turning off the service that is related to the data connection and is turned on, and controlling the processor to enter the sleep mode, the service related to the data connection and the use of the processor may be turned off, and the power consumption of the mobile terminal device in a standby state may be reduced. Compared with the prior art, more services and apparatuses consuming energy are turned off, and the power consumption of the mobile terminal device is saved more than that in the prior art, so the use time of the mobile terminal device is prolonged more. Furthermore, on the basis of Embodiment 1, because the non-core process is killed or turned off, the energy consumption of the mobile terminal device may be further reduced.
In this embodiment, after the mobile terminal device is slept, if the user needs to enable the slept mobile terminal device again, the user needs to wake the mobile terminal device. When the user needs to use the mobile terminal device, the current mobile terminal device is waked through a user operation, and the current mobile terminal device may also be waked through an automatic system selection wake function of the mobile terminal device.
Corresponding to Embodiment 1, Embodiment 2, Embodiment 3, and Embodiment 4, descriptions are made separately below.
FIG. 5 is a flowchart of a wake method according to Embodiment 5 of the present invention.
In this embodiment, corresponding to Embodiment 1, step S 50 : when determining that a mobile terminal device needs to be waked, wake a processor that has entered sleep.
In this embodiment, when the processor is a single-core processor, the application service of the processor may be waked first, and then the communication service of the processor is waked; or only the application service of the processor may be waked, and the communication service of the processor is not waked, or which is understood as follows, the application service of the processor is waked first, and then whether to wake the communication service of the processor is determined; or the application service and the communication service of the processor may be waked simultaneously.
In this embodiment, the procedure that the application service of the processor may be waked first, and then the communication service of the processor is waked; or only the application service of the processor may be waked, and the communication service of the processor is not waked may include:
after waking the application service of the processor, determining whether the current mobile terminal device is inserted with a SIM card and whether an offline mode is not turned on;

when determining that the current mobile terminal device is inserted with the SIM card and the offline mode is turned on, or the mobile terminal device is not inserted with the SIM card and the offline mode is turned on, or the mobile terminal device is not inserted with the SIM card and the offline mode is not turned on, not waking the communication service of the processor.
When the processor is a dual-core processor, it is required to wake a processor for processing a communication service and a processor for processing an application service, where the processor for processing an application service may be waked first, and then the processor for processing a communication service is waked; or only the processor for processing an application service may be waked, and the processor for processing a communication service is not waked; or the processor for processing an application service and the processor for processing a communication service may be waked simultaneously.
When the processor is a quad-core processor, it is required to wake a processor for processing a communication service and a processor for processing an application service, where the processor for processing an application service may be waked first, and then the processor for processing a communication service is waked; or only the processor for processing an application service may be waked, and the processor for processing a communication service is not waked; or which is understood as follows, the processor for processing an application service is waked first, and then whether to wake the processor for processing a communication service is determined; or the processor for processing an application service and the processor for processing a communication service may be waked simultaneously.
The rest may be deduced by analogy. If the processor is a multi-core processor, it is required to wake a processor for processing a communication service and a processor for processing an application service.
In this embodiment, the procedure that a processor for processing an application service may be waked first, and then whether to wake a processor for processing a communication service is determined may include:
after waking the application service of the processor, determining whether the current mobile terminal device is inserted with a SIM card and whether an offline mode is not turned on;
when determining that the current mobile terminal device is inserted with the SIM card and the offline mode is not turned on, waking the communication service of the processor;
when determining that the current mobile terminal device is inserted with the SIM card and the offline mode is turned on, or the mobile terminal device is not inserted with the SIM card and the offline mode is turned on, or the mobile terminal device is not inserted with the SIM card and the offline mode is not turned on, not waking the communication service of the processor.
In this embodiment, the procedure of determining that a mobile terminal device needs to be waked may include:
detecting whether the power key of the current mobile terminal device is pressed, or detecting whether the power interface of the current mobile terminal device is inserted with a power line, or detecting whether the HDMI of the current mobile terminal device is inserted with an HDMI line, or detecting whether the SIM card of the current mobile terminal device is plugged or unplugged, which may also be understood as follows, detecting whether an event that a power key is pressed occurs, or whether an event that a power interface is inserted with a power line occurs, or whether an event that an HDMI is inserted with an HDMI line occurs, or whether an event that a SIM card is plugged or unplugged occurs in the current mobile terminal device;
if detecting that the power key of the current mobile terminal device is pressed, or detecting that the power interface of the current mobile terminal device is inserted with the power line, or detecting that the HDMI of the current mobile terminal device is inserted with the HDMI line, or detecting that the SIM card of the current mobile terminal device is plugged or unplugged, determining that the mobile terminal device needs to be waked, which may also be understood as follows, if detecting that the event that the power key is pressed occurs, or the event that the power interface is inserted with the power line occurs, or the event that the HDMI is inserted with the HDMI line occurs, or the event that the SIM card is plugged or unplugged occurs in the current mobile terminal device, determining that the mobile terminal device needs to be waked;
if detecting that the power key of the current mobile terminal device is not pressed, or detecting that the power interface of the current mobile terminal device is not inserted with the power line, or detecting that the HDMI of the current mobile terminal device is not inserted with the HDMI line, or detecting that the SIM card of the current mobile terminal device is not plugged or unplugged, determining that the mobile terminal device does not need to be waked, which may also be understood as follows, if detecting that the event that the power key is pressed does not occur, or the event that the power interface is inserted with the power line does not occur, or the event that the HDMI is inserted with the HDMI line does not occur, or the event that the SIM card is plugged or unplugged does not occur in the current mobile terminal device, determining that the mobile terminal device does not need to be waked.
Step S 52 : restore a service that is related to data connection and is in a turn-on state and is turned off in a sleep mode, so that the mobile terminal device enters a system. In this embodiment, the service related to the data connection includes GPS, WIFI, and Bluetooth. Before entering sleep, the mobile terminal device records current information of the turn-on state and the turn-off state of the service, and when entering sleep, the mobile terminal device needs to turn off the service that is related to the data connection and is in the turn-on state, so at the time of waking the mobile terminal device, the service that is related to the data connection and is in the turn-on state and is turned off in the sleep mode needs to be restored.
After the steps are executed, it may be considered that the mobile terminal device is waked, and the mobile terminal device enters the system and displays a boot screen.
In the wake method provided in the embodiment of the present invention, when it is determined that the mobile terminal device needs to be waked, by waking the processor that has entered sleep and restoring the service that is related to the data connection and is in the turn-on state and is turned off in the sleep mode, the mobile terminal device is waked, and the mobile terminal device enters the system and displays a boot screen. Compared with the prior art in which a normal startup procedure makes a user wait for a very long time, it is not required to execute operations of initializing the system and loading each system program in the startup procedure in the prior art, and it is only required to wake the processor that has entered sleep and restore the service that is related to the data connection and is in the turn-on state and is turned off in the sleep mode, the mobile terminal device can be quickly waked, and the mobile terminal device enters the system and displays a boot screen. In this way, the user does not need to select a power-off manner to save the power consumption of the mobile terminal device, and when a mobile phone is required, the user does not need to start up the mobile terminal device again to enable it to begin normal work, thereby greatly improving user experience.
In this embodiment, with the wake method provided in the embodiment of the present invention, the mobile terminal device may be quickly waked in the time of 2S.
In this embodiment, alternatively, on the basis of FIG. 5 , an additional operation may be added optionally. For example, when it is determined that the mobile terminal device needs to be waked, a wake effect is displayed through an animation or a wait box on a display screen of the mobile terminal device, or a wake progress is prompted through a sound. Definitely, the operation may be performed together with other steps simultaneously. In this embodiment, if an additional operation may be added optionally on the basis of FIG. 5 , the time for waking the mobile terminal device may be prolonged, but is still shorter than the startup time of the prior art. In this embodiment, an additional operation may be added optionally, and the mobile terminal device may be quickly waked in the time of 5S. Meanwhile, the wake effect of the current mobile terminal device may also be prompted for the user at any time, thereby improving user experience.
Alternatively, if killing or turning off a non-core process is executed in a sleep procedure, in a wake procedure, after the service that is related to the data connection and is in the turn-on state and is turned off in the sleep mode is restored, a starting complete message is sent to an application in the mobile terminal device, so as to implement that a service running in need of startup begins to run in a startup procedure. In this embodiment, if an additional operation may be added optionally on the basis of FIG. 5 , the time for waking the mobile terminal device may be prolonged, but is still shorter than the startup time of the prior art. In this embodiment, an additional operation may be added optionally, and the mobile terminal device may be quickly waked in the time of 5S.

Accordingly, FIG. 9 is a structural diagram of a mobile terminal device according to Embodiment 1 of the present invention.
In this embodiment, a recording unit 90 , a turn-off unit 92 , and a control unit 94 are provided.
The recording unit 90 is configured to, when it is determined to select sleep of a mobile terminal device, record service state information related to data connection. In this embodiment, a service related to the data connection includes GPS, WIFI, and Bluetooth. In this embodiment, when the mobile terminal device is normally used, the service may have a current use state, so when the mobile terminal device enters sleep, the mobile terminal device records current information of a turn-on state and a turn-off state of the service, and the recorded state information is to be subsequently used to wake the mobile terminal device.
The turn-off unit 92 is configured to, according to the service state information related to the data connection recorded by the recording unit 90 , turn off the service that is related to the data connection and is in a turn-on state. In this embodiment, turning off the service that is related to the data connection and is turned on includes turning on an offline mode and turning off GPS.
The control unit 94 is configured to, after the turn-off unit 92 turns off the service that is related to the data connection and is in the turn-on state, control a processor to enter a sleep mode. In this embodiment, when the processor is controlled to enter the sleep mode, the processor does not process communication and application services again. In this embodiment, the processor may be controlled to enter the sleep mode by setting the current running state of the processor to a sleep state.
In this embodiment, the processor may include multiple models of processors, such as a single-core processor, a dual-core processor, and a quad-core processor. In this embodiment, when the processor is a single-core processor, because a communication service and an application service are processed by one processor, the single-core processor is directly controlled to enter the sleep mode; when the processor is a dual-core processor, it is required to control a processor for processing a communication service and a processor for processing an application service to enter the sleep mode; when the processor is a quad-core processor, it is required to control a processor for processing a communication service and a processor for processing an application service to enter the sleep mode. The rest may be deduced by analogy. When the processor is a multi-core processor, it is required to control a processor for processing a communication service and a processor for processing an application service to enter the sleep mode.
In this embodiment, after the application service of the processor enters the sleep mode, the mobile terminal device turns off its screen, that is, it indicates that the mobile terminal device has entered the sleep mode.
In this embodiment, the mobile terminal device may further include a sleep determining unit 91 , where the sleep determining unit 91 is configured to determine whether to select sleep of the mobile terminal device. In this embodiment, the sleep determining unit 91 determines whether to select sleep of the mobile terminal device in a user manual selection manner or an automatic system selection manner. Separate descriptions are made below.
First case: when whether to select sleep of the mobile terminal device is determined in a user manual selection manner, the following may be included.
When the sleep determining unit 91 detects that a user presses a power key on the mobile terminal device manually for a long time, the sleep determining unit 91 prompts whether the user selects to enter a sleep mode or enter a power-off mode through a selection box.
When the user selects the sleep mode, the recording unit 90 begins to record the service state information related to data connection, that is, the recording unit 90 is configured to, when the sleep determining unit 91 determines to select sleep of the mobile terminal device, record the service state information related to data connection.
When the user selects the power-off mode, the mobile terminal device executes a normal power-off procedure, that is, it is powered off, and in this case, the mobile terminal device may further include a power-off module (not shown), configured to execute a normal power-off procedure.
The mobile terminal device may provide an application for selecting sleep to be selected by the user manually, this application for selecting sleep may be displayed on a touch screen of the mobile terminal device, and when whether to select sleep of the mobile terminal device is determined in the user manual selection manner, the sleep determining unit 91 detects whether the user triggers the application for selecting sleep. When the sleep determining unit 91 detects that the user triggers the application for selecting sleep, the sleep determining unit 91 determines that the user selects the sleep mode, and the recording unit 90 begins to record the service state information related to data connection. That is, the recording unit 90 is configured to, when the sleep determining unit 91 determines to select sleep of the mobile terminal device, record the service state information related to data connection.
When whether to select sleep of the mobile terminal device is determined in the user manual selection manner, the following may be further included. The mobile terminal device provides a selection box for selecting to enter the sleep mode in a system setting interface, so as to be selected by the user.
When detecting that the user presses the power key on the mobile terminal device manually for a long time, the sleep determining unit 91 determines whether a selection box of the sleep mode in the system setting interface is selected.
If it is determined that the selection box of the sleep mode in the system setting interface is selected, that is, the sleep determining unit 91 determines that the user selects the sleep mode, the recording unit 90 begins to record the service state information related to data connection. That is, the recording unit 90 is configured to, when the sleep determining unit 91 determines to select sleep of the mobile terminal device, record the service state information related to data connection.
If it is determined that the selection box of the sleep mode in the system setting interface is not selected, that is, it is determined that the user does not select the sleep mode, the mobile terminal device executes a normal power-off procedure, that is, it is powered off.
Alternatively, when it is determined that the selection box of the sleep mode in the system setting interface is not selected, the sleep determining unit 91 may further prompt whether the user selects to enter the sleep mode or enter the power-off mode through a selection box.
Second case: when whether to select sleep of the mobile terminal device is determined in an automatic system selection manner, the following may be included.
When the sleep determining unit 91 detects that a user selects power-off, the sleep determining unit 91 detects whether the mobile terminal device is currently in a charging state, or whether a high definition multimedia interface (High Definition Multimedia Interface, HDMI) is inserted with an HDMI line.
When the sleep determining unit 91 detects that the mobile terminal device is currently in the charging state or the HDMI is inserted with the HDMI line, the sleep determining unit 91 determines to perform a normal power-off procedure.
When the sleep determining unit 91 detects that the mobile terminal device is not in the charging state currently or the HDMI is not inserted with the HDMI line, the sleep determining unit 91 automatically selects the sleep mode in place of power-off, and the recording unit 90 begins to record the service state information related to data connection. That is, the recording unit 90 is configured to, when the sleep determining unit 91 determines to select sleep of the mobile terminal device, record the service state information related to data connection.
When a power interface and a USB interface on the mobile terminal device are different, and when whether to select sleep of the mobile terminal device is determined in the automatic system selection manner, the sleep determining unit 91 is further configured to detect whether an event that the power interface is inserted with a power line occurs. When detecting that the event that the power interface is inserted with the power line occurs, the sleep determining unit 91 automatically selects the sleep mode in place of power-off.
Definitely, when the power interface and the USB interface on the mobile terminal device are the same, and when the sleep determining unit 91 detects that an event that the USB interface is inserted with a USB line occurs, the sleep determining unit 91 determines to perform a normal power-off procedure.
In the mobile terminal device provided in the embodiment of the present invention, by turning off the service that is related to the data connection and is turned on, and controlling the processor to enter the sleep mode, the service related to the data connection and the use of the processor may be turned off, and the power consumption of the mobile terminal device in a standby state may be reduced. Compared with the prior art, more services and apparatuses consuming energy are turned off, and the power consumption of the mobile terminal device is saved more than that in the prior art, so the use time of the mobile terminal device is prolonged more, and a user does not need to select a power-off manner to save the power consumption of the mobile terminal device.
