Detailed description of the invention

In embodiments of the present invention, the running status of terminal specifically may include that normal operating condition, holding state, resting state, but above-mentioned three kinds of states can not constitute the restriction to the embodiment of the present invention, as long as the technical scheme making the system of terminal change between different conditions according to embodiments of the present invention, it is the technical scheme described in the embodiment of the present invention.

Fig. 1 is the flow chart of the power consumption control method of some embodiments of the invention, and the method may be used on terminal unit, and this terminal unit can be the intelligent mobile terminal of mobile phone, panel computer etc.

As it is shown in figure 1, the power consumption control method of the present embodiment comprises the following steps:

Step 102, obtains the current operating conditions of the system of terminal.

In the present embodiment, the current operating conditions of terminal includes normal operating condition, holding state, resting state. Normal operating condition refers to that terminal is being in use state, for instance receiving the input of user, exporting information to user etc. In order to reduce electric quantity consumption, when user does not use terminal, for instance terminal is when exceeding the input that the scheduled time does not receive user, and terminal can be switched to holding state from normal operating condition. During holding state, terminal is in open state, and in order to reduce electric quantity consumption, fractional hardware module is closed, and part of module is in running order. For mobile phone, during holding state, display screen is closed, and processor is then in running order (such as processing background task). In order to reduce electric quantity consumption further, terminal can be switched to park mode under given conditions, and in such a mode, most hardware modules are closed, and the hardware module only retained needed for realizing necessary function is in running order. For mobile phone, during resting state, almost the hardware module of other except baseband processor is all closed, and baseband processor is in running order to ensure to receive the basic communication functions such as incoming call, note normally. In general, the time needed for making mobile terminal breaking dormancy state is longer than the time needed for releasing holding state, but the electric energy that resting state consumes is less.

Step 104, when system is in holding state and does not have task to process, then the interval estimated current time with run between the wakeup time that tentation data business is corresponding next time.

In certain embodiments, after the tactile power key by terminal of user or terminal are not received by user's input in the given time, screen is closed, and system enters holding state. Holding state can make whole system be in low energy consumption state. When reusing terminal, system can exit holding state rapidly and also can Exact recovery to standby front state.

In certain embodiments, do not have task to process the electronic equipment referred to such as mobile phone terminal etc. described in be in open state but do not stop the background task being switched to resting state by holding state. For the mobile phone based on Android operation system, user touches the power key by terminal or after terminal is not received by user's input in the given time, can be introduced into the sub-state of earlysuspend (namely above in holding state); Then judging whether to enter the sub-state of suspend (namely above in resting state) according to wakelock situation, under usual condition, earlysuspend power consumption is still higher, and suspend state power consumption is non-normally low. Under wakelock mechanism, certain application program can utilize dormancy to intercept interface and perform locking (acquire) or release (release) two kinds of operations. When some application program performs acquire operation, then it represents that this application program intercepts dormancy to system application, system is not now allowed to enter the sub-state of suspend; When application program performs release operation, then release intercepts the application of dormancy. Under wakelock mechanism, only when all of application program of system discovery is all not carried out acquire operation, the sub-state of suspend can be entered. For the mobile phone based on Android operation system, " not stoping the background task being switched to resting state by holding state " refers to be absent from backstage performing the above-mentioned acquire application program operated.

Tentation data business is often referred to and connects terminal and server long and connect or GPS (GlobalPositioningSystem, global positioning system) positions the data service of such high power consumption.

In the present embodiment, the step of the interval estimating current time and run between the wakeup time that tentation data business is corresponding next time includes:

(1) meansigma methods at interval between adjacent twice wakeup time that described tentation data business is corresponding is calculated.

As shown in Figure 2, run GPS module before obtaining current time and position the wakeup time of correspondence, then the meansigma methods at interval between the wakeup time of all adjacent twice is calculated, using this meansigma methods as current time and the interval run between the wakeup time that tentation data business is corresponding next time. In the present embodiment, in 9s, terminal is waken up 10 times because of GPS, and the interval waken up is 0.9s. Therefore current time is 0.9s with the interval run between the wakeup time that tentation data business is corresponding next time.

Or the behavioural habits of terminal (2) are used according to user, statistics runs the interval between adjacent twice wakeup time corresponding to tentation data business, and using this interval as current time and the interval run between the wakeup time that tentation data business is corresponding next time.

In the present embodiment, it is possible to excavate the rule at the interval run between adjacent twice wakeup time that tentation data business is corresponding according to the method for machine learning. Such as, the behavioural habits of terminal can be used according to user, the method prediction utilizing linear regression runs the interval between adjacent twice wakeup time corresponding to tentation data business, and using this interval as current time and the interval run between the wakeup time that tentation data business is corresponding next time.

Step 106, it is judged that whether described interval is more than scheduled time threshold value, if it is, perform step 108, otherwise, then perform step 110.

In the present embodiment, by the interval that judges current time and run between the wakeup time that tentation data business is corresponding next time whether more than preset time threshold, thus determining whether to allow system enter resting state.

Step 108, controls system and enters resting state.

In the process entering dormancy, first system can freeze all processes that can freeze, then the power supply of all devices (hardware module of terminal) is hung up successively, hang-up order is contrary with the order of facility registration, this ensure that the dependency of power supply between equipment, until finally entering battery saving mode, wait that user or RTC (Real-TimeClock, real-time clock) wake up.

When terminal returns to normal operating condition in resting state, the state before dormancy can be reverted to, and terminal is less when the electric energy that resting state consumes is than holding state.

Step 110, starts time-out lock mechanism, controls terminal and maintains current operating conditions.

In certain embodiments, described time-out lock refers to that controlling system in the given time does not start program or the instruction set of dormancy flow process. When described interval is less than or equal to scheduled time threshold value, terminal starts time-out lock mechanism, controls the system of terminal and maintains the power dissipation ratio of current operating state and enter low in energy consumption when being awakened as frequently as those utilized in conventional solutions of resting state.

Owing to the terminal of mobile phone etc. can enter resting state by complete machine when not having task to process, when having Chief Web Officer connection, GPS to position the situations such as unlatching, terminal can be awakened as frequently as those utilized in conventional solutions. And wake up requirements of process process things a lot, such as, wake up all of processor (such as CPU, GPU etc.), peripheral hardware (such as USB interface), all of process status is reverted to dormancy before state and the notice waken up of transmission etc., these processes can cause the big electric current of long period, greatly accelerates terminal power consumption.

Such as shown in Fig. 3, when terminal has interruption frequently to wake system up in resting state, the average current of system is about: 81mA, and wherein each little crest represents and once wakes up. As shown in Figure 4, when there is no task run, maintain current operating conditions and do not allow the system dormancy, the average current of system be: 58mA. Therefore, under the scenes such as the connection of networking length, GPS, average current when system maintains current operating state is less than average current when frequently waking up, can reach the purpose of power saving on the contrary.

Further, in certain embodiments, when system maintains current operating state, the time reaching to discharge time-out lock is constantly judged whether, if so, then release time-out lock, hereafter, repeated execution of steps 102 to step 110.

Further, in certain embodiments, terminal can also periodically point out user to arrive the residual time length of the time that release time-out is locked. So may remind the user that and will not operate for a long time and make terminal enter resting state, improve Consumer's Experience.
