Background
Smart phones are Smart portable terminals that combine the functions of a PDA (Personal Digital Assistant) and allow clients to browse web pages and send and receive e-mails. In order to save power, the smart portable terminal usually reduces power consumption of hardware itself, and turns off devices that are not currently in an operating state, or makes the devices enter a low power consumption state, thereby reducing power consumption of the smart portable terminal as a whole and prolonging service life.
The intelligent portable terminal adopts an architecture combining an AP (Application Processor) and a CP (Communication Processor) when realizing functions, wherein the AP completes functions such as audio and video playing, document reading and processing and the like; the CP provides a communication channel for the application processor to realize a communication function. Because the network wireless signal of the intelligent portable terminal can change along with the different positions of the terminal, when the CP learns that the wireless network signal changes, the AP in the dormant state can be awakened, the AP reads the wireless network signal through the CP, and the signal display on the display screen is updated according to the read signal, so that the user of the intelligent portable terminal can know the current wireless network signal state in real time.
The inventor finds in the research process of the prior art that when a wireless network signal changes, both the AP and the CP are in an operating state, not in a sleep state with low power consumption, and particularly when the intelligent portable terminal is in a mobile state, frequent changes of the wireless network signal may be caused, and at this time, the AP may not perform other application processes except for updating a signal display, and a user does not pay attention to the wireless network signal change at this time, but the AP still needs to be awakened from the sleep state continuously according to the frequent changes of the network signal, thereby increasing the power consumption of the intelligent portable terminal.

Detailed Description
In some embodiments of the present invention, a method for controlling a state of a portable terminal is provided, and some embodiments provide a portable terminal including a first processor and a second processor, the second processor detecting a state change value of a first application of the terminal, acquiring a state of the first processor when the state change value of the first application exceeds a preset threshold, notifying the first processor of the state change value when the first processor is in a first state, and maintaining a second state of the first processor when the first processor is in the second state, wherein power consumption of the first processor in the first state is greater than power consumption in the second state.
In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
In practical applications, the first processor may be specifically an AP processor, that is, an X86 architecture processor, and the second processor may be specifically a CP processor, that is, an ARM architecture processor, but this is only described as an example. According to the specific type of the mobile terminal, in fact, the first processor and the second processor may be both ARM architecture processors, or both X86 architecture processors, or other architecture processors, etc., that is, the combination of the processors of different kinds is not limited in the embodiments of the present invention.
The first embodiment of the state control method of the portable terminal of the present invention has the flow as shown in fig. 1:
step 101: the second processor detects a state change value of a first application of the terminal.
The first application may specifically be some low-timeliness applications in the terminal, that is, when the first processor is in a low power consumption state, the application state may not need to be updated. The method can comprise the following steps: the second processor detects the state of the wireless signal of the terminal; or the second processor detects a status of network registration of the terminal.
Specifically, the second processor detects a first state value of the first application at a first time, detects a second state value of the first application at a second time, and obtains a state change value of the first application according to the first second processor and the second state value.
Step 102: when the state change value of the first application exceeds a preset threshold value, the state of the first processor is acquired.
Step 103: judging the working state of the first processing, and if the working state is the first state, executing the step 104; if the state is the second state, step 105 is executed, wherein the power consumption of the first processor in the first state is larger than the power consumption in the second state.
Step 104: and the second processor informs the first processor of the state change value and ends the current process.
Step 105: and maintaining the second state of the first processor, and ending the current flow.
The second embodiment of the method for controlling the state of the portable terminal according to the present invention is shown in fig. 2, and the embodiment shows the process of displaying and controlling the wireless signal after the portable terminal is initially turned on and the signal strength notification function of the communication processor is turned on:
step 201: after the portable terminal is powered on, the communication processor starts a signal strength notification function.
Step 202: judging the state of the application processor, if the state is a working state, executing step 203; if the power saving state is determined, step 206 is executed.
Wherein, the working state can include: the display module is in a lighting state; or the state of the signal intensity needs to be displayed; the power saving state may include: the display module is in a dark screen state; or the display module is in a screen protection state; or a status that does not require display of signal strength.
Step 203: the communication processor detects that the state change value of the wireless signal exceeds a preset threshold value.
For example, the signal strength of the wireless signal varies to the extent that the signal strength display is altered, such as from 100% to 75%.
Step 204: the communication processor transmits the wireless signal to the application processor through the signal strength notification function.
The communication processor transmits the detected wireless signal to a communication port of the communication processor, and the communication port of the communication processor transmits the wireless signal to the application processor by interacting with the communication port of the application processor.
Step 205: and the application processor controls the display module to display the wireless signal according to the received wireless signal, and ends the current flow.
After the application processor receives the new wireless signal, the new wireless signal is used for updating the wireless signal originally displayed by the display module, so that a portable terminal user can know the change condition of the wireless signal in real time.
Step 206: the communication processor detects that the state change value of the wireless signal exceeds a preset threshold value.
Step 207: the communication processor sends a command to the application processor for triggering the application processor to enter an active state.
At this time, although the application processor is in a power saving state, since the initial signal strength notification function is already turned on, after the communication processor detects a changed wireless signal, it needs to wake up the application processor, that is, send a trigger command to a power management module of the application processor, so that the application processor enters an operating state. The awakened application processor enters the power saving state again after meeting the condition of entering the power saving state.
Step 208: when the number of times that the communication processor transmits the command exceeds a preset threshold within a preset time, the application processor transmits a command to turn off the signal strength notification function to the communication processor.
For example, the preset threshold value within the preset time may be 2 times per minute, and when the number of times that the communication processor transmits the command is greater than 2 times per minute, the application processor transmits a command to turn off the signal strength notification function to the communication processor.
Step 209: and the communication processor stops detecting the wireless signal after receiving the command of closing the signal strength notification function and ends the current flow.
In addition, step 209 may also be that after receiving the command to turn off the signal strength notification function, the communication processor stores the change value of the detected wireless signal exceeding the threshold value, and does not send the change value to the application processor, and ends the current flow, and after the application processor is awakened for other reasons and enters the operating state, the application processor sends the state change value exceeding the threshold value, which is stored in advance, to the application processor.
By applying the embodiment, when the application processor enters the power-saving state, the communication processor can be controlled to close the signal strength notification function, so that the application processor does not need to update the wireless signal display in real time when the wireless signal changes frequently, and the power consumption of the portable terminal is reduced.
The third embodiment of the method for controlling the state of the portable terminal according to the present invention is shown in fig. 3, and the embodiment shows the process of displaying and controlling the wireless signal after the portable terminal is initially turned on and the signal strength notification function of the communication processor is turned off:
step 301: after the portable terminal is powered on, the communication processor turns off the signal strength notification function.
Step 302: judging the state of the application processor, and if the state is a working state, executing step 303; if the power saving state is determined, step 309 is executed.
Wherein, the working state can include: the display module is in a lighting state; or the state of the signal intensity needs to be displayed; the power saving state may include: the display module is in a dark screen state; or the display module is in a screen protection state; or a status that does not require display of signal strength.
Step 303: the application processor sends a command to the communication processor to turn on the signal strength notification function.
Step 304: the communication processor detects that the state change value of the wireless signal exceeds a preset threshold value.
Step 305: the communication processor transmits the wireless signal to the application processor through the signal strength notification function.
Step 306: the application processor controls the display module to display the wireless signals according to the wireless signals.
Step 307: judging whether the application processor is to enter a power saving state, if so, executing step 308; otherwise, return to step 306.
Step 308: the first processor sends a command to the second processor to turn off the signal strength notification function.
Step 309: the second processor stops sending the wireless signal to the first processor, and the current flow is ended.
In the above embodiments, when the application processor enters a power saving state (e.g., sleep), the wake-up function of the low-timeliness application (e.g., radio signal strength display) of the communication processor is controlled to be turned off, and when the application processor is in an operating state, the communication processor is notified to turn on the wake-up function. The low-timeliness application can comprise a plurality of applications, a list of the low-timeliness application can be stored in the application processor in advance, and the application processor respectively sends a plurality of pieces of closing information to the communication processor when entering a power-saving state; or the list of the low-timeliness applications can be stored in the communication processor in advance, the application processor only sends a piece of closing information to the communication processor, and the communication processor closes each application according to the list.
By applying the embodiment, the portable terminal normally enters the power-saving mode after being initially started, so that the signal intensity notification function is initially set to be closed so as to save the power consumption of the portable terminal; and because when the application processor enters the power-saving state from the working state, the signal strength notification function can be closed by controlling the communication processor, when the wireless signal changes frequently, the application processor does not need to update the wireless signal display in real time, and the power consumption of the portable terminal is reduced.
