Description

Power saving method and device for mobile terminal

The present invention relates to the field of terminal communication, and in particular to a power saving method and apparatus for a mobile terminal. Background technique

Mobile terminals, such as mobile phones, have the battery's endurance capability a high requirement. The user wants the mobile terminal to have the standby time as long as possible after one charge; especially after the mobile communication technology enters the 3G era, the mobile terminal services with large power consumption are gradually increased, such as mobile terminal television, web surfing, online games, MP3 playback, video playback, etc., these services are increasingly demanding the capabilities of mobile terminal batteries. Therefore, the battery life of mobile terminal batteries is becoming a very powerful competitive point in the competition of mobile terminal products, and it has become a key technical point restricting the development of mobile terminal services.

There are many factors affecting the battery life of a mobile terminal. In the design of a mobile terminal, the method and strategy of how the mobile terminal service/application/device uses the battery is a key aspect that affects the battery life of the mobile terminal. Generally, when a mobile terminal dials a call, answers an incoming call, operates a keyboard, or touches a screen, it lights up the LCD lighting component and the keyboard light. After the user has not operated the mobile terminal for a period of time (the length of time can pass through the mobile terminal Set the application to turn off the display backlight backlight time and keyboard light time), the mobile terminal turns off the LCD lighting components and keyboard lights; especially the straight mobile terminal, considering its own design, in order to avoid the user inadvertently on the keyboard and screen The mobile terminal is mishandled by the contact, and the mobile terminal is generally activated from the sleep state by pressing a specific key.

The above setting, although it is possible to obtain a certain power saving effect by turning off the display lighting component and the keyboard light, the disadvantage is that the display lighting component and the brightness time of the keyboard light It is fixed, so the inevitable existence time is too long and too short. In particular, for different applications, the user's desired display backlight time and keyboard light time are different. For example, the user may need to think when performing certain games. The setting time is too short, and the user has to touch the keyboard or the touch screen while thinking to avoid the closing of the display lighting component of the mobile terminal. For the mobile phone terminal, it is necessary to press the specific button from time to time to activate the mobile terminal from the sleep state, which is a bad feeling of the user experience; if the setting time is too long, it is very likely to consume the battery power of the mobile terminal, especially For the bar mobile terminal, it is necessary to avoid inadvertent touch before the mobile terminal sleeps to start some applications.

For the backlight of the mobile terminal display, the application number is 02278368, and the Chinese patent entitled "Power Saving Mobile Phone" proposes a scheme for determining whether to turn the backlight of the display on or off from the ambient light intensity; Application No. 200320127073 The Chinese patent entitled "Mobile Phone Sensing Power Saver", Application No. 200710070516.3, and the Chinese patent entitled "Mobile Phone Display Bright-Control Device" are all similar. The Chinese patent for the device that can automatically save power after the invention is named 03110413 is the solution to the control of the backlight of the display during the process of receiving the phone.

However, none of these methods solves the problem of users having different display backlight/keyboard hours for different applications, and does not consider the user experience for the backlight/keyboard duration of the straight mobile terminal display. Summary of the invention

The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The invention mainly solves the problems of poor user experience and waste of battery power caused by the fixed setting of the display backlight time and the keyboard light time of the mobile terminal. The mobile terminal described herein generally refers to a terminal that is used by a user, such as a mobile phone, a PDA (Personal Data Assistant) device, and the like. In the present invention, the term "bright state" is used to characterize the display screen and/or the keyboard light to illuminate Whether or not the mobile terminal is "on a bright state" means that the display backlight and/or the keyboard light is turned on. When the mobile terminal is "not in the bright state", the display backlight and/or the keyboard light is turned off.

The method for saving power of the mobile terminal of the present invention includes:

A. sensing whether the mobile terminal is in a handheld state when the mobile terminal is in a bright state;

B. When the mobile terminal is not in the handheld state, the mobile terminal is turned off. In the present invention, when the mobile terminal is in the handheld state, the mobile terminal is maintained in a bright state, that is, the display backlight and/or the keyboard light are not turned off; when the mobile terminal is not in the handheld state, the mobile terminal is turned off, that is, the display backlight is turned off. And / or keyboard lights.

As shown in FIG. 1, the figure exemplarily describes the structure of the light state adjusting device of the mobile terminal of the present invention, that is, the device for saving power of the mobile terminal of the present invention, and only the mobile terminal is related to the inventive concept of the present invention. The partial structure, other functional structures of the mobile terminal, are well known to those skilled in the art and will not be described again.

The device illustrated in FIG. 1 includes: a handheld state sensing unit 102, configured to sense whether the user is using the mobile terminal, that is, whether it is in a handheld state when the mobile terminal is in a bright state; the light state adjustment unit 104, according to the handheld state sense The sensing result of the measuring unit 102, when the mobile terminal is not in the handheld state, turns off the light state of the mobile terminal, that is, the operation state of the mobile terminal by the user, determines whether the user needs to use the backlight of the display screen and/or the keyboard light, once it is determined that the user does not If you need to use the display backlight and / or keyboard light, then turn it off.

Specifically, the light state adjustment unit 104 includes:

The policy judging subunit 1041 is configured to determine, according to the sensing result of the handheld state sensing unit 102, when the mobile terminal is not in the handheld state, determine to turn off the light state of the mobile terminal; and further, when the mobile terminal is in the handheld state, determine not to close The light state of the mobile terminal (ie, determining whether the user currently needs to use the display backlight and/or the keyboard light;);

The operation execution sub-unit 1042 is configured to determine, according to the determination result of the sub-unit 1041 according to the policy, that when the light state of the mobile terminal needs to be turned off, the light-off state is turned off. Specifically, The method of instant closing or delay closing is adopted; when the light state of the mobile terminal is not required to be turned off, the light state of the mobile terminal is maintained (that is, the display backlight and/or the keyboard light are turned off or not turned off). .

The handheld state sensing unit 102 is further configured to perform sensing of the handheld state of the mobile terminal by using at least one of pressure sensing, light sensing, and temperature sensing; and also for sensing the handheld state by using a periodic sensing manner Measurement. Among them, the pressure sensing method shown in FIG. 2 adopts a method of installing a pressure sensor at one or more specific positions of the mobile terminal. Generally, when a user holds a mobile terminal and performs business use, the location of the handheld mobile terminal is as shown in FIG. 2 . When the left hand is held, as shown in Figure 2a, the palm touches point A, the thumb touches point B, the ring finger or the little finger touches point C; when the right hand is held, as shown in Figure 2b, the palm touches point A, thumb Touch point B, ring finger or little finger touch point C. For the holding mode in which the palm is slightly above the A point, points B and C are also touch points. Therefore, installing the pressure sensor at points A, B, and C shown in Fig. 2 is a typical mounting position. It should be understood that the installation position shown in FIG. 2 is only some exemplary installation positions, and the installation position and the number of the pressure sensors are not limited thereto. For example, on the same side of point C, a plurality of pressure sensors may be arranged in an equally spaced manner or in an unequal interval manner. Generally, above the point C, a touch of the index or middle finger may be sensed. Of course, the three pressure sensor settings at three specific positions, such as the bottom position and the middle upper position on the side of the mobile terminal, and the lower side of the other side of the mobile terminal, as shown in FIG. 2, fully consider the user. In the conventional case of hand-held use, on the one hand, it has a flexible sensing effect, on the other hand, it can also fully save the number of pressure sensors, which is a practically effective setting method. For the light sensing method or the temperature sensing method, the implementation principle is basically similar to the pressure sensing method, except that the pressure sensor is replaced by a light sensor or a temperature sensor, and the mounting position can refer to the pressure sensing. The location of the pressure sensor installation. The light sensor can be judged by whether the optical signal is blocked by the mobile terminal, and the temperature sensor can set the sensing similar to the human body temperature. When the temperature close to the body temperature is sensed, the terminal can be judged to be in the handheld state. . As shown in FIG. 3, the light state adjustment process of an embodiment of the present invention includes the following steps: Step 100: Capture a signal at pressure sensors at points A, B, and C, according to whether the pressure sensor captures a signal. Determining whether the user is using the mobile terminal by hand; if the user is using the mobile terminal in hand, proceeding to step 200; otherwise, proceeding to step 600. Note that the pressure sensor capture signal is not processed in the standby state, ie when the mobile terminal is not in the bright state.

Step 200: If the user is using the mobile terminal by hand, obtain the currently used application from the task management of the mobile terminal system software, and determine whether it is currently the call state of the voice call. If the currently used application is the call state of the voice call, go to step 300, otherwise go to step 500.

Step 300: If the user holds the mobile terminal and is in a call, obtain the headset usage status from the mobile terminal task management, determine whether the headset is used for the call; if the headset is currently used for the call, go to step 600, otherwise go to step 400.

Step 400: Determine whether the user's handheld state has changed. If the process proceeds to step 600, go to step 500.

If the handheld status changes, indicating that the user is no longer using the mobile terminal, the process proceeds to step 600 where the display backlight and/or keyboard light can be turned off; otherwise, step 500 is entered.

In step 500, the display backlight and the keyboard light are not turned off.

In step 600, the display backlight and the keyboard light are turned off.

The above embodiment not only has the judgment adjustment of the handheld state, but also combines the task management in the mobile terminal system software, and adjusts some current application states of the mobile terminal, such as call call state, earphone application state, etc., so as to move The terminal lighting state is more reasonably adjusted, so that it can have better power saving effect and user experience. Alternatively, only one of a combination of a call state or a headset use state, or one or more of other application states, can also provide good results. Of course, simply, when the mobile terminal is sensed to be in a handheld state, the light state of the mobile terminal is maintained, so that, for example, the user thinks in the game and grows In the scene where the time does not touch the terminal, the terminal does not turn off the light state, and thus can bring a better experience to the user.

When the light state is turned off, there are two ways to turn off, one is to turn off immediately, that is, to turn off the light state immediately; the other is to turn off the time delay, that is, after a short delay. The purpose of the short delay is to ensure that when the user adjusts the handheld state for a short period of time, the bright state is not turned off and misjudgment is avoided. Generally speaking, this time is preferably 3 to 5 seconds according to the experience of the mobile terminal user. Generally, when entering the delay off state, the handheld state sensing is performed again during the short delay period, and when the confirmation is still in the non-handheld state, the bright state is turned off, and if the handheld state is sensed, the previous time can be judged. The non-handheld state may be that the user adjusts the handheld state for a short period of time, and does not need to turn off the bright state, so the bright state is not turned off after a short delay.

Hand-held state sensing can be initiated when the terminal enters a bright state and ends when the light state is turned off. In addition, the sensing of the hand-held state can also be performed in a periodic sensing manner so that sensing of the hand-held state can be continuously maintained. In this way, as long as the appropriate sensing period is set to ensure that there is at least one sensing during the short delay, it is not necessary to start the sensing separately during the short delay.

It can be seen from the above that the present invention fully recognizes the user's handheld state to the mobile terminal and the mobile terminal application used, and effectively determines whether the user needs to use the display backlight and/or the keyboard light, which not only satisfies the user's display well. The need for screen backlighting and/or keyboard light experience; and to ensure that the display backlight and / or keyboard lights need to be bright, no need to be closed, compared to the current method, not only can effectively reduce the battery power consumption, Moreover, according to the user's use status of the mobile terminal, the duration of the light state can be intelligently adjusted, and is closer to the user's needs, thus having a better user experience.

The above is a further detailed description of the present invention in connection with the specific preferred embodiments, but this is only an example for ease of understanding, and the specific implementation of the present invention should not be construed as being limited to the description. For those of ordinary skill in the art to which the present invention pertains, On the premise of the inventive concept, various possible equivalent changes or substitutions may be made, and such changes or substitutions are intended to fall within the scope of the present invention.
