Description

Device and method for controlling standby in a mobile terminal

technical field

The invention relates to the field of mobile communication, in particular to a device and method for controlling standby in a mobile terminal.

Background technique

Currently, digital mobile terminals have various standards, such as Global System for Mobile Communication (GSM) communication standard, Time Division-Synchronous Code Division Multiple Access (TimeDivision-Synchronous Code Division Multiple Access, TD-SCDMA) communication standard, Personal Handy-phone System (PHS) communication standard, wideband code division multiple access (wideband CDMA, WCDMA) communication standard, etc. Among them, each standard and the communication network matching the standard have their own characteristics in terms of signal coverage, signal emission strength, construction and operation costs, communication costs, etc. Each standard mobile terminal also has its own characteristics in terms of software and hardware implementation. different. However, no matter what kind of standard mobile terminal, in order to save power consumption, it must enter a sleep state when not in use, that is, to achieve a standby state, that is, a low power consumption state. The power consumption of the mobile terminal can be subdivided into two parts: one part is the power consumption generated by running the code, that is, the power consumption caused by the resources of each part of the CPU that the running program needs to consume, called the code power consumption; the other part is the power consumption caused by turning on a certain The power consumption caused by a peripheral such as a camera is called device power consumption. The opening and closing of the device is controlled by codes. Most of the current mobile terminal standby mode is to enter the standby mode only when all the codes are not running. The disadvantage is that as long as there are codes running, the entire mobile terminal will be disabled. It cannot enter the standby mode. For example, when the camera is working, the Bluetooth function of the mobile terminal is also in the working mode, but at this time there is no event that requires Bluetooth to work, that is, the current standby mode still has a part of power consumption that is wasted.

Contents of the invention

The technical problem to be solved by the present invention is to provide a device for controlling the standby of the mobile terminal that effectively reduces power consumption according to the characteristics of the power consumption of the mobile terminal, and propose a method for controlling the standby of the mobile terminal based on the device.

The device for controlling standby in the mobile terminal of the present invention includes a system power supply module, a master clock module, and an operating system module in the mobile terminal. The operating system module includes functional modules, and each functional module is used to execute the The self-identification is set as the working mode; when there is no task execution within the set time, the self-identification is set to enter the standby mode. The device also includes a standby module, and the standby module also includes a function for recording functions in the operating system module. Mode identification module for module standby information. According to the standby information of each functional module recorded in the mode identification module, the standby module controls to turn off the system power supply module and the main clock module when the entire system can enter the standby state, so that the entire system enters the standby state. Standby mode; in standby mode, if there is an external event trigger, the control system will enter the working mode, and at the same time set the functional modules related to the triggering event to the working mode; if the standby information of each functional module is that some functional modules can enter the standby mode mode, the standby module enables the corresponding functional module to enter the standby mode.

The functional modules in the operating system module include a man-machine interface (Man Machine Interface, MMI) module, a protocol stack (Protocol Stack, PS) module, an AT command set (Attention Command, ATC) module and a Bluetooth (Blue Tooth, BT) module. module.

The standby module also includes a mode identification module for recording standby information of each functional module in the operating system module.

The method for controlling standby in the mobile terminal of the present invention comprises the following steps:

Step 1: Divide the operating system module of the mobile terminal into relatively independent modules according to their functions. When each independent module has a task to perform, set its own identification as the working mode; when each independent module has no task to perform within the set time, set the The self-identification is set to enter the standby mode;

Step 2: In the system working mode, the standby module regularly monitors the identification information of each independent module in step 1. If the identification information of an independent module changes, the information of the module is passed to the mode identification module to update the information in the mode identification module. corresponding data;

Step 3: the standby module queries the data of the mode identification module, if the data of the mode identification module is that some independent modules can enter the standby mode, then the standby module makes the part of the independent modules enter the standby mode; if the data of the mode identification module is all independent modules can enter Entering the standby mode, the standby module makes the whole system enter the standby mode.

The third step is in the standby mode of some modules, if there is an event trigger that needs to be executed by the independent module in the standby mode, the standby module first sets the data of the independent module in the standby mode to the working mode, and then notifies the independent module to execute the event .

Said step three is in the system standby mode, if there is an event trigger, the standby module first controls the operating system module to enter the working mode, and simultaneously sets the data of the independent module related to the triggering event in the mode identification module to the working mode, and then notifies the operating system The corresponding independent module execution event in the module.

Part of the independent modules entering the standby mode in Step 3 refers to turning off the power of the independent modules that can enter the standby mode.

Entering the standby mode of the whole system in Step 3 refers to turning off the system power supply module and the main clock module.

The system entering the working mode refers to turning on the system power supply module and the main clock module.

Compared with the prior art, the present invention can realize hierarchical standby management of mobile terminals, and can also decide to turn off the power supply of standby modules according to the standby information of each module of the present invention so as to reduce power consumption as much as possible.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the operating system is divided into an MMI module, a PS module, an ATC module and a BT module in the present embodiment, and the standby module is located between these modules and the system power supply module and the main clock module of the mobile terminal, and the standby module is connected to the main clock module of the mobile terminal. There is information exchange between each module. The standby module also includes a mode identification module, named Sleep_mode, which is used to record the standby information of each module. It is essentially a global variable, which can be Word type, half-word or byte type, mainly depending on the system. The number of modules that can be divided depends. In this embodiment, the word type is used, and the remaining bits are reserved for future expansion of system functions. Each bit of sleep_mode represents whether different modules can enter the sign of the standby state, where bit=1 represents that the module represented by this bit cannot enter the standby mode, and bit=0 represents that the module represented by this bit can enter the standby mode.

As shown in Figure 2, after the operating system is divided into independent modules, when the mobile terminal is in the working mode, the standby module monitors each module. If the identification information of any module changes, the standby module transmits the information to sleep_mode, so that the sleep_mode The bit bit that marks the module is set or cleared.

The standby module also regularly checks the value of each meaningful bit of sleep_mode. If sleep_mode=0x00000000, it means that the entire system can enter the standby state. The standby module controls the shutdown of the system power module and the main clock module, so that the entire mobile terminal system enters the standby state. mode; in standby mode, if there is an external event trigger, the standby module control system enters the working mode, and at the same time, the module related to the triggering event is set to the working mode. If any bit is 0, make the corresponding module enter the standby mode so as to reduce power consumption as much as possible.

In the standby mode of some modules, when the standby module detects that a module in standby mode has a task to run, the standby module first needs to set the corresponding bit of the module to 1, and then perform other operations. When the module can enter the standby mode again, the corresponding bit of the module needs to be cleared. For example, the MMI module, when receiving a button message, the screen lights up, and the user's menu operation needs to be processed. At this time, the flag indicating whether the MMI can enter the standby state should be set to 1, indicating that the MMI cannot enter the standby state now. When the user no longer operates the menu , and when there are no other events such as an incoming call that require the MMI module to run, it is necessary to clear the flag bit indicating whether the MMI can enter the standby mode.

The invention divides the mobile terminal operating system into a plurality of relatively independent modules according to the functions. When each module has no task execution within the set time, it can set its own identification to enter the standby mode, and at the same time, a special standby module collects all The standby information of the module controls the standby of the entire system. When the system is woken up manually such as a button, an incoming call event, or an active wake-up such as a specific internal timer, the standby module will turn on the system-related power module, turn on the main clock, and at the same time will be related to the wake-up The identification of the module related to the event is set so that the module cannot enter standby, so that when the standby module collects the standby information of each module again, if the module is still processing the wake-up event, the standby module will not cause the entire system to enter the dormant state.
