BACKGROUND At present, with the widespread popularity of Android (Android) smart phones, multi-processor and multi-wireless smart phones have become hotspots in current technology research and development. Multiprocessors are implemented with one application processor for user-oriented applications and another baseband processor for baseband signal processing. The baseband chip in a multi-radio system may also be multiple processors. This type of phone needs to read the system image file from memory (eg flash, eMMC) and load it into RAM when booting. It takes a long time from system startup and image verification to the user's ability to operate the mobile application interface. Especially for multi-processor multi-radio smartphones, the system will take longer to load, usually in thirty seconds. One minute. If the user needs to turn the phone on and use it in an emergency, the above loading time will be unacceptable to the user. The solutions proposed in the related art are generally focused on optimizing the boot process and increasing the operating frequency of the processor at boot time. However, these technical solutions have limited optimization of the boot speed, and the operating frequency of the processor cannot be provided indefinitely. It can be seen that there is a lack of a solution in the related art that enables the smart mobile terminal to be quickly started. SUMMARY OF THE INVENTION The embodiments of the present invention provide a method and an apparatus for shutting down a mobile terminal, so as to at least solve the problem that the startup speed of the smart mobile terminal in the related art is slow.

In the related art, the startup speed of the smart mobile terminal is slow. The method shown in FIG. 1 is used to obtain a shutdown operation instruction; and the current operation state information of the baseband processor and the application processor is saved according to the shutdown operation instruction, wherein the stored operation state information is used after the mobile terminal is restarted. Restoring the mobile terminal to the running state, that is, when the mobile terminal is powered off, the entire system (including the application system and the baseband system) is not actually powered off, but the current operating state information of the baseband processor and the application processor is saved. . In this shutdown state, only part of the battery power is required, and the current is the bottom current of the system, and the shutdown state can be maintained for a long time, so that a faster startup start speed can be obtained at the expense of a small amount of system bottom current. Therefore, the problem that the startup speed of the smart mobile terminal in the related art is slow is solved, thereby effectively shortening the time taken for the smart mobile terminal to complete the booting, and greatly improving the booting speed of the smart mobile terminal.

The startup time of the smart mobile terminal using the related art is 30 seconds to 1 minute, and the startup time of the smart mobile terminal can be shortened to less than 10 seconds by using the technical solution provided by the embodiment of the present invention. Preferably, in step S104, saving the running state information may include the following operations: Step S1: maintaining a low power state in which the baseband processor and the application processor are powered on and turning off the clock; Step S2: information about the running state Stored on the baseband processor and application processor. In a preferred embodiment, the baseband processor and the application processor coexist in the following three modes in a low power state:

(1) Idle Mode; (2) Sleep Mode;

(3) Power Off Mode. If the baseband processor and the application processor are in modes (1) and (2), then the baseband processor and the application processor are still powered up and the clock needs to be turned off at this time. Since the baseband processor and the application processor are not powered down, information on the operational status can be stored on the baseband processor and the application processor. Preferably, in step S104, saving the running state information may include the following steps: Step S3: maintaining a low power consumption state in which the baseband processor and the application processor are powered off and the clock is turned off; Step S4: The information of the running state is stored in a preset storage area other than the baseband processor and the application processor. If the baseband processor and the application processor are in the above mode (3), the baseband processor and the application processor cannot store the information of the running state because they are in a power-down state. To this end, it is necessary to separately open a memory space inside the mobile terminal, and the memory space is always in a power-on state for storing information of the running state. Preferably, in step S1, maintaining the baseband processor and the application processor in the power-on state may include the following processing: Step S11: controlling the rest of the baseband system except the baseband processor to enter the flight mode and controlling the baseband processor to enter Idle mode or sleep mode; Step S12: After the upper application and the display are closed, the application processor is controlled to enter an idle mode or a sleep mode. In a preferred embodiment, when the mobile terminal is powered off, the entire system is not actually powered off, but the application processor in the application system and the baseband processor in the baseband system are all in idle mode or sleep mode, in the baseband system. The rest of the baseband processor enters flight mode. Preferably, in step S3, maintaining the baseband processor and the application processor in a power-down state may include the following steps: Step S31: Control the baseband system to enter a power-down mode; Step S32: After turning off all upper-layer applications and displays, control The application system enters the power down mode. Since it is necessary to open up additional storage space in addition to the baseband processor and the application processor, it is possible to control both the baseband system and the application system to enter the power down mode, and store the current operating state information of the baseband processor and the application processor in Extra open storage space. Preferably, in the above step S11, controlling the rest of the baseband processor to enter the flight mode and controlling the baseband processor to enter the idle mode or the sleep mode may include the following operations: sending a notification message to the baseband system, wherein the notification message is used The portion other than the baseband processor is notified to enter the flight mode and the baseband processor is notified to enter the idle mode or the sleep mode. In a preferred embodiment, the smart mobile terminal (eg, a smart phone) responds to the user's shutdown operation, the application system starts playing the shutdown animation, and then sends an AT command (AT+CFUN=4) to the baseband system to notify the baseband system of the baseband processor. The rest of the mode enters the flight mode, and after the baseband system receives the notification message from the application system, enters the flight mode, and the baseband processor enters the idle mode or the sleep mode. 2 is a flow chart of shutdown of an intelligent mobile terminal in accordance with a preferred embodiment of the present invention.

In this shutdown state, only part of the battery power is consumed. The current is the bottom current of the system, and the bottom current of the system is very low, usually around 1 mA. For a normal 1000 mAh battery, the shutdown state can be It lasts for more than a month, so it is economical to use a system with a small amount of system bottom current to get a faster start-up speed, especially in special occasions. The smart mobile terminal (for example: smart phone) can respond to the user's long button power-on operation or the alarm timeout, long button interrupt or RTC clock interrupt can wake up the application processor, and the application system plays the boot animation. The application system runs the necessary upper-layer applications preset (for example: the screen displays the desktop, and the WIFI is turned on). Preferably, before the step S14 is executed, the application processor may further include the following steps: Step S15: After the application processor is woken up, continue to wake up the baseband processor. That is, while the boot animation of the smart mobile terminal is playing, the application system also needs to wake up the baseband processor.
