FIG. 2 is a schematic diagram of a hardware structure of a communication connection between a mobile terminal and an external device in an embodiment of the present invention. In the embodiment of the present invention, the mobile terminal 100 is connected to the external device 200 through a preset interface (Universal Serial Bus, Universal Serial Bus). The mobile terminal 100 includes a first processing chip 001 and a first radio frequency module 12 connected to the first processing chip 001 . Wherein, the first processing chip 001 includes a first application processor (Application Processor) 10, a first modem 11 (modem1) connected to the first subscriber identification card 13 and the second subscriber identification card 14 and RPM (ResourcePower Manager, resource power supply Manager) 15. The external device 200 includes a second processing chip 002 and a second radio frequency module 22 connected to the second processing chip 002 . Wherein, the second processing chip 002 includes a second application processor 20 and a second modem (modem2) 21 . The subscriber identification card is a SIM card.

The internal framework of the first application processor 10 and the second application processor 20 includes an application layer, a framework layer, etc., which can handle complex logic operations and perform task allocation. In one embodiment, the application processor refers to the Android operating system and various apks (Android Package, Android installation package) based on the Android operating system. The first application processor 10 and the second application processor 20 are connected through USB, provide an interactive interface for the user, and transmit the operation instruction input by the user (for example, the operation instruction about starting a video call input by the user through the user interface) to the second application processor 10. A modem 11 or a second modem 21 is used to realize the definition and transfer of data between two processors, for example, to control the sleep, wake-up, and synchronization of two application processors, and to control the chip startup sequence when switching on and off.

The first application processor 10 is connected to the second application processor 20 through a preset interface to realize the connection between the mobile terminal 100 and the external device 200 , wherein the preset interface is USB. In the embodiment of the present invention, the USB multiplexes three data channels, which are respectively used for the interaction of user data, signaling data and SIM card authentication data between the first application processor 10 and the second application processor 20 . That is, the first application processor 10 and the second application processor 20 transmit user data, signaling data and SIM card authentication data through USB. Among them, user data includes but is not limited to data generated by surfing the Internet, pictures and chat information data; signaling data includes but not limited to control data for turning on and off the machine, control data for turning on and off flight mode, and control data for displaying status signals; SIM card authentication The data includes but not limited to IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number) and Ki (key identifier, authentication key).

Specifically, the first application processor 10 and the second application processor 20 perform data interaction through OTG (On-The-Go) technology. Through OTG technology, the first modem 11 in the mobile terminal 100 can access the eNodeB 101 through the SIM card parameters in the second subscriber identity card 14 or the first subscriber identity card 13, and the second modem 21 can access the eNodeB 101 through the second subscriber identity card 14 or the SIM card parameters of the first subscriber identity card 13 to access the eNodeB 101, the SIM card parameters include but not limited to SIM card authentication data.

The first modem 11 and the second modem 21 comprise the protocol stack of the network standard of various network interactions, and the protocol stack comprises LTE/WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access)/GSM (Global System for Mobile Communication, global Mobile communication system)/TD-SCDMA (TimeDivision-Synchronous Code Division Multiple Access, synchronous time division code division multiple access)/CDMA (Code Division Multiple Access, code division multiple access)/EDGE (Enhanced Data Rate for GSMEvolution, strong data rate GSM evolution technology) and other communication standards stipulated in the protocol code. The mobile terminal 100 interacts with the operator's network through a protocol, that is, performs data traffic Internet access, VOLTE (Voice Over LTE) phone calls or CS (Circuit Switched, circuit switched) domain phone calls. The first modem 11 and the second modem 21 are also used for managing and controlling the SIM card and the like.

In the embodiment of the present invention, the first radio frequency module 12 is used for processing the data transmitted by the mobile terminal 100 to the eNodeB 101 (base station network), and for processing the data transmitted by the eNodeB 101 to the mobile terminal 100 . The second radio frequency module 22 is used for processing the data transmitted by the external device 200 to the eNodeB 101 (base station network), and for processing the data transmitted by the eNodeB 101 to the external device 200 .

The first subscriber identification card 13 and the second subscriber identification card 14 are used to provide relevant data required by mobile communication services (CS voice service, PS data service and PS voice service), and store user information, short messages, execution Authentication algorithm and generate encryption key, etc.

The first subscriber identity card 13 and the second subscriber identity card 14 may store subscriber information associated with different or same technical standards. In a specific non-limiting example, the technical standard may be 2G communication technology (eg, GSM, EDGE), 3G communication technology (eg, WCDMA, TD-SCDMA), 4G communication technology (eg, LTE), or any other mobile communication technology Technology (eg, 4G, etc.). The first subscriber identity card 13 and the second subscriber identity card 14 are preferably SIM cards.

When the first subscriber identification card 13 and the second subscriber identification card 14 interact with the mobile terminal 100, the signal that the mobile terminal 100 detects the existence of the subscriber identification card is only generated at the moment of starting the power. You will be prompted to "Insert Subscriber Identification Card". After the mobile terminal 100 is powered on, the mobile terminal 100 communicates with the subscriber identification card once every 28 seconds to complete some fixed communication checks (for example, whether the subscriber identification card is in place, etc.).

Since the current mobile terminal 100 has only one set of radio frequency modules, when the mobile terminal 100 has two subscriber identification cards, the radio frequency used by the two subscriber identification cards of the mobile terminal 100 is time-division multiplexed and cannot be occupied at the same time. For example, when the two SIM cards are fully activated, one of the SIM cards only handles GSM calls, while the other handles 4G network information. The details of which SIM card executes which network will not be discussed here. limited. Therefore, the current radio frequency dual-card time-division multiplexing architecture only achieves LTE+GSM (that is, the technical standard corresponding to one subscriber identification card is LTE, and the technical standard corresponding to the other subscriber identification card is GSM).

It can be understood that although the existing mobile terminal 100 can support dual user identification cards, when the mobile terminal 100 is registered with the network, the two user identification cards support networks of different technical standards, and one supports 2G or 3G , and the other one supports 4G, which will make the Internet traffic speed slower when the mobile terminal 100 is in use. In the embodiment of the present invention, the mobile terminal 100 is connected to the external device 200 via USB. Since the external device 200 includes a second modem 21 and a second radio frequency module 22, and the second radio frequency module 22 supports a 4G network, the mobile terminal 100 can pass The USB interacts with the external device 200, so that the mobile terminal 100 has dual LTE functions (at this time, the technical standards managed by the first subscriber identification card 13 and the second subscriber identification card 14 are all LTE standards, and the first radio frequency module 12 and the second radio frequency The radio access technology involved in module 22 is LTE).

The RPM15 of the mobile terminal 100 is used to control various resources, including clock resources, bus resources, PMIC (PowerManagement IC, power management integrated circuit, namely the voltage of each chip), DDR (memory allocation), and the interruption of sleep wake-up of the management chip and application processor wake-up deadlines. Each subsystem of the mobile terminal 100 applies for resources to the RPM15 when resources are needed, and each subsystem includes a first application processor 10, a first modem 11, a PRONTO (WIFI/Bluetooth, NFC (Near Field Communication, Near Field Communication) ), etc.), LPASS (Low power audio subsystem, low power audio subsystem), RPM15 is used to determine the sleep state of the mobile terminal 100 system, specifically, RPM15 is based on the voting mechanism of each subsystem. Only when the ticket is activated, the RPM 15 can make the entire system of the mobile terminal 100 sleep. However, when one or more subsystems of the mobile terminal 100 vote against dormancy, the entire system of the mobile terminal 100 cannot be dormant.

After the entire system of the mobile terminal 100 is dormant, if it is to be restarted, the first application processor 10 needs to be woken up for data transmission and interaction.

In the case that the mobile terminal 100 and the external device 200 are connected through USB communication, the wake-up methods can be the following three ways:

1. When the first application processor 10 receives the signaling data, it sends a handshake keyword to the second application processor 20 via USB, so as to wake up the second application processor 20 .

2. When the second modem 21 receives the user data, it wakes up the second application processor 20 , and the second application processor 20 sends the handshake key to the first application processor 10 via USB, so as to wake up the first application processor 10 .

3. The second modem 21 periodically searches for paging requests to actively activate itself. If a paging request is received, the second modem 21 wakes up the second application processor 20 , and the second application processor 20 sends a handshake key to the first application processor 10 via USB to wake up the second application processor 20 .

It should be noted that the handshake keyword can be identified by a character with a fixed word length, which is a field that does not appear in a normal data packet. For example, 0xF9F9F9 or 0x9F9F9F can be used to represent the handshake keyword, and the first application processor 10 or the second application processor 20 in a sleeping state can be woken up by the handshake keyword.

In addition, the second modem 21 can wake itself up periodically, so as to perform handshake interaction with the base station when the mobile terminal 100 performs location update, and the first application processor 10 does not need to be woken up at this time.

Referring to FIG. 3 , FIG. 3 is a schematic diagram of the physical structure of the communication connection between the mobile terminal 100 and the external device 200 according to the present invention. The mobile terminal 100 communicates with the external device 200 via USB, wherein the mobile terminal includes but is not limited to a mobile phone, PC (Personal Computer, personal computer) or PAD (Personal Digital Assistant, personal digital assistant), and the external device 200 includes but not limited to a wireless Network card and data card. It should be noted that the connection position between the mobile terminal 100 and the external device 200 via USB is not limited to that shown in FIG. 3 , and the connection position between the mobile terminal 100 and the external device 200 via USB can be set according to specific needs.

Various embodiments of the present invention are proposed based on the above-mentioned LTE network architecture diagram, a schematic diagram of the hardware structure of the communication connection between the mobile terminal 100 and the external device 200 , a schematic diagram of the physical structure, and problems in the prior art.

A method for controlling the mobile terminal 100 of the present invention is proposed.

Referring to FIG. 4 , FIG. 4 is a schematic flowchart of a first embodiment of a method for controlling a mobile terminal 100 according to the present invention.

In this embodiment, an embodiment of the control method of the mobile terminal 100 is provided. It should be noted that although the logic sequence is shown in the flow chart, in some cases, all the steps may be executed in a different sequence than here. steps shown or described.

In this embodiment, the mobile terminal 100 is connected to an external device 200 through a preset interface, and the mobile terminal 100 includes a first application processor 10 and a first modem 11 connected to a first subscriber identification card 13 and a second subscriber identification card 14 ; The external device 200 includes a second application processor 20 and a second modem 21 . In the embodiment of the present invention, the preset interface is a USB interface, and the mobile terminal 100 and the external device 200 perform data transmission through OTG technology. In other embodiments, the preset interface may also be other interfaces capable of data transmission. The external device 200 has a built-in power supply, through which the external device 200 can supply power for itself, and the mobile terminal 100 is no longer required for power supply.

The embodiments of the present invention are implemented by a software code kernel (Kernel) running on a CPU (Central Processing Unit, central processing unit) of the mobile terminal 100, specifically, by a power management module in the kernel.

The mobile terminal 100 control method includes:

Step S10, when it is detected that the mobile terminal 100 enters the black screen state from the bright screen state, acquire the black screen time when the mobile terminal 100 enters the black screen state.

In step S20, if the black screen time is greater than or equal to the preset threshold, it is judged whether the current running state of the mobile terminal 100 satisfies the preset condition.

When it is detected that the mobile terminal 100 enters the black screen state from the bright screen state, the dormancy callback function preset in the mobile terminal 100 is called to control the mobile terminal 100 to enter the dormancy state. In the embodiment of the present invention, when the mobile terminal 100 enters the black screen state from the bright screen state, the duration time that the mobile terminal 100 is in the black screen state is obtained, that is, the black screen time is obtained. Specifically, when the mobile terminal 100 enters the black screen state, a timer with an initial value of zero may be started, and the black screen time of the mobile terminal 100 may be calculated through the timer.

When the black screen time of the mobile terminal 100 is acquired, it is judged whether the black screen time is greater than or equal to a preset threshold. If the black screen time is greater than or equal to the preset threshold, it is judged whether the current operating state of the mobile terminal 100 satisfies the preset condition; if the black screen time is less than the preset threshold, then continue to calculate the black screen time of the mobile terminal 100 by the timer. Wherein, the preset threshold can be set according to specific needs, for example, it can be set to 30s (seconds), 35s or 42s and so on.

Further, the step of judging whether the current operating state of the mobile terminal 100 satisfies a preset condition includes:

Step a, judging whether the black screen time is less than or equal to the first preset time.

Step b, if the black screen time is less than or equal to the first preset time, then detect whether the preset interface has not transmitted data within the second preset time, and whether only the OTG driver holds the dormancy lock in the mobile terminal.

The specific process of judging whether the current running state of the mobile terminal 100 satisfies the preset condition is: judging whether the black screen time of the mobile terminal 100 is less than or equal to the first preset time. If the black screen time of the mobile terminal is less than or equal to the first preset time, it is detected that the preset interface does not transmit data within the second preset time, and whether only the OTG driver holds a sleep lock (wake lock) in the mobile terminal. It should be noted that, when there is any valid sleep lock in the mobile terminal 100, the mobile terminal 100 will not enter deep sleep. It can be understood that judging whether the preset interface has not transmitted data within the second preset time means that neither the mobile terminal 100 nor the external device 200 has transmitted data through the preset interface within the second preset time. Wherein, the first preset time and the second preset time can be set according to specific conditions, such as the first preset time can be set to 110s, 120s, or 126s; the second preset time can be set to 4s, 5s or 8s, etc. .

Step c, if the preset interface does not transmit data within the second preset time, and only the OTG driver in the mobile terminal 100 holds the dormancy lock, then determine that the running state satisfies the preset condition.

Step d, if the preset interface does not transmit data within the second preset time, and more than OTG drivers in the mobile terminal 100 hold the dormancy lock, then determine that the running state does not meet the preset condition.

Step e, if the preset interface transmits data within the second preset time, and only the OTG driver in the mobile terminal 100 holds the dormancy lock, it is determined that the running state does not meet the preset condition.

Step f, if the preset interface transmits data within the second preset time, and more than OTG drivers in the mobile terminal 100 hold the dormancy lock, it is determined that the running state does not meet the preset condition.

If the preset interface has not transmitted data within the second preset time, and only the OTG driver in the mobile terminal 100 holds the sleep lock, then it is determined that the current running state of the mobile terminal 100 satisfies the preset condition. If the preset interface has not transmitted data within the second preset time, and more than OTG drivers in the mobile terminal 100 hold the dormancy lock, it is determined that the current operating state of the mobile terminal 100 does not meet the preset condition. If the preset interface has transmitted data within the second preset time, and more than OTG drivers in the mobile terminal 100 hold the dormancy lock, it is determined that the current operating state of the mobile terminal 100 does not meet the preset condition. If the preset interface has transmitted data within the second preset time, and only the OTG driver in the mobile terminal 100 holds the dormancy lock, it is determined that the current operating state of the mobile terminal 100 does not meet the preset condition.

Step g, if the black screen time is longer than the first preset time, then detect whether only the OTG driver in the mobile terminal 100 holds the dormancy lock.

In step h, if only the OTG driver holds the dormancy lock in the mobile terminal, it is determined that the running state meets the preset condition.

In step i, if more than one OTG driver in the mobile terminal 100 holds the dormancy lock, it is determined that the running state does not meet the preset condition.

If the black screen time of the mobile terminal 100 is greater than the first preset time, it is detected whether only the OTG driver in the mobile terminal 100 holds the sleep lock. If only the OTG driver holds the dormant lock in the mobile terminal 100, then it is determined that the current operating state of the mobile terminal 100 meets the preset condition; Meet the preset conditions.

If the black screen time of the mobile terminal 100 is greater than the first preset time, and only the OTG driver holds the dormancy lock in the mobile terminal 100, then it is determined that the current running state of the mobile terminal 100 meets the preset condition; if the black screen time of the mobile terminal 100 is less than or is equal to the first preset time, and/or more than OTG drivers in the mobile terminal 100 hold the sleep lock, then it is determined that the running state of the mobile terminal 100 does not meet the preset condition.

Step S30, if the running state satisfies the preset condition, control the mobile terminal 100 to exit the host mode and enter the dormant state.

If the current operating state of the mobile terminal 100 satisfies the preset condition, the mobile terminal 100 is controlled to exit the host mode and enter the dormant state. It can be understood that, the mobile terminal 100 entering the dormant state mentioned in this embodiment means that the mobile terminal 100 enters the deep dormancy state. When the mobile terminal 100 enters the dormant state, the voltage output port in the preset interface will no longer have voltage output, that is, the VBUS (Voltage Bus, voltage output port) in the USB interface will no longer have voltage output.

Step S40, if the running state does not meet the preset condition, it is judged whether the running state satisfies the preset condition again after the second preset time period elapses.

When the current running state of the mobile terminal 100 does not meet the preset condition, it is judged again after the second preset time period whether the current running state of the mobile terminal satisfies the preset condition. Wherein, the second preset duration can be set according to specific needs, for example, it can be set to 4s, 5s or 8s.

In this embodiment, when it is detected that the mobile terminal 100 enters the black screen state from the bright screen state, the black screen time when the mobile terminal 100 enters the black screen state is obtained; if the black screen time is greater than or equal to the preset threshold, then the current operating state of the mobile terminal 100 is judged Whether the preset condition is met; if the running state satisfies the preset condition, the mobile terminal 100 is controlled to exit the host mode and enter a sleep state. It is realized that in the process of dual LTE communication of the mobile terminal 100 through the external device 200, the external device 200 supplies power to itself through the built-in power supply, and the mobile terminal 100 enters a sleep state when certain conditions are met, so as to save the power of the mobile terminal 100.

Further, a second embodiment of the method for controlling the mobile terminal 100 of the present invention is proposed.

The difference between the second embodiment of the mobile terminal 100 control method and the first embodiment is that, referring to FIG. 5 , the mobile terminal 100 control method further includes:

Step S50 , when detecting that the mobile terminal 100 enters a bright screen state from a black screen state, it is detected whether the preset interface is in an idle mode.

Step S60 , if the preset interface is in the idle mode, control the mobile terminal 100 from the idle mode to enter the host mode, so as to wake up the mobile terminal 100 .

When it is detected that the mobile terminal 100 enters the bright screen state from the black screen state, the wake-up callback function preset in the mobile terminal 100 is called to control the mobile terminal 100 to enter the host mode. When the mobile terminal 100 enters the bright screen state from the black screen state, it detects whether the preset interface is in the idle mode, that is, detects whether the USB interface is in the idle mode. Wherein, the idle mode in this embodiment is the b_idle mode known to those skilled in the art. If the preset interface is in the idle mode, control the mobile terminal 100 from the idle mode to the host mode to wake up the mobile terminal 100, so that the mobile terminal 100 enters the wake-up state from the dormant state.

Further, the control method of the mobile terminal 100 also includes:

In step j, if the preset interface is not in the idle mode, check whether the preset interface is in the idle mode again after the first preset time period elapses.

If the preset interface is not in the idle mode, it is detected again whether the preset interface is in the idle mode after the first preset time period elapses. Wherein, the first preset duration can be set according to specific needs, for example, it can be set to 2s, 3s or 5s.

In this embodiment, when the mobile terminal 100 enters the bright screen state from the black screen state, it first detects whether the preset interface of the mobile terminal 100 is in the idle mode. Only when the preset interface is in the idle mode, the mobile terminal 100 is controlled to enter the host mode to wake up the mobile terminal 100 . It avoids that when the mobile terminal 100 just enters the black screen state, it immediately enters the bright screen state, that is, when the mobile terminal 100 has not completely entered the idle mode, it enters the host mode, causing the confusion of the USB interface state machine, thereby causing the mobile terminal 100 Failed to enter host mode.

Further, a third embodiment of the method for controlling the mobile terminal 100 of the present invention is proposed.

The difference between the fourth embodiment of the mobile terminal 100 control method and the first and/or second embodiment is that the mobile terminal 100 control method further includes:

Step k, detecting whether the mobile terminal 100 enters a black screen state from a bright screen state for the first time after being turned on.

When the mobile terminal 100 enters the black screen state from the bright screen state, it is detected whether the mobile terminal 100 enters the black screen state from the bright screen state for the first time after being turned on. If the mobile terminal 100 enters the black screen state from the bright screen state for the first time after starting up, it is judged whether the black screen time during which the mobile terminal 100 is in the black screen state is greater than or equal to a preset first threshold.

Further, in this embodiment, a state flag is set in the mobile terminal 100, through which it can be determined whether the mobile terminal 100 enters a black screen state from a bright screen state for the first time after being turned on. Specifically, when the mobile terminal 100 enters the black screen state from the bright screen state, if the state identification at this time is the first identification, it indicates that the mobile terminal 100 enters the black screen state from the bright screen state for the first time after powering on; If the identifier is the second identifier, it means that it is not the first time that the mobile terminal 100 enters the black screen state from the bright screen state after being turned on. Wherein, the state flag can be set according to specific needs, as long as it can distinguish whether the mobile terminal 100 enters the bright screen state from the black screen state for the first time after it is turned on. For example, the first identifier can be set to 00, and the second identifier can be set to 01, or the first identifier can be set to 11, and the second identifier can be set to 10, etc.

In step 1, if the mobile terminal 100 enters the black screen state from the bright screen state for the first time after starting up, it is judged whether the black screen time is greater than or equal to a preset first threshold.

If the mobile terminal 100 enters the black screen state from the bright screen state for the first time after starting up, it is judged whether the black screen time during which the mobile terminal 100 is in the black screen state is greater than or equal to a preset first threshold. Among them, in order to ensure that the mobile terminal 100 has completed the network registration operation when the mobile terminal 100 enters the black screen state from the bright screen state for the first time after powering on, therefore, the preset first threshold value should be set a little larger (relative to the preset second threshold value). threshold). For example, the preset first threshold may be set to 55s, 60s, or 70s.

Step S20 includes:

In step a1, if the black screen time is greater than or equal to a preset first threshold, it is judged whether the current operating state of the mobile terminal 100 satisfies a preset condition.

If the black screen time of the mobile terminal 100 in the black screen state is greater than or equal to a preset first threshold, it is judged whether the current running state of the mobile terminal 100 satisfies a preset condition. Further, if the black screen time of the mobile terminal 100 in the black screen state is less than the preset first threshold, continue to calculate the black screen time of the mobile terminal 100, and determine whether the black screen time of the mobile terminal 100 is greater than or equal to the preset first threshold.

In this embodiment, when the mobile terminal 100 enters the black screen state from the bright screen state for the first time after starting up, only when the black screen time of the mobile terminal 100 is greater than or equal to the preset first threshold value, the current operation of the mobile terminal 100 is judged. Whether the state satisfies the preset condition, avoiding that when the mobile terminal 100 first enters the black screen state from the bright screen state after starting up, the mobile terminal 100 has not yet completed the network registration operation, and then enters the dormant state, thereby causing the mobile terminal 100 network registration fail.

Further, a fourth embodiment of the method for controlling the mobile terminal 100 of the present invention is proposed.

The difference between the fourth embodiment of the mobile terminal 100 control method and the third embodiment is that the mobile terminal 100 control method further includes:

In step m, if the mobile terminal 100 enters the black screen state from the bright screen state not for the first time after starting up, it is judged whether the black screen time is greater than or equal to the preset second threshold, wherein the preset second threshold is smaller than the preset first threshold.

When the mobile terminal 100 does not enter the black screen state from the bright screen state for the first time after being turned on, it is determined whether the black screen time of the mobile terminal 100 is greater than or equal to a preset second threshold. It can be understood that when the mobile terminal 100 enters the black screen state from the bright screen state not for the first time after booting, it indicates that the mobile terminal 100 has completed the network registration operation, therefore, the preset second threshold is set to be smaller than the preset first threshold. The preset second threshold can be set according to specific needs, such as 26s, 30s, or 33s.

Step S20 includes:

In step a2, if the black screen time is greater than or equal to the preset second threshold, it is judged whether the current running state of the mobile terminal 100 satisfies the preset condition.

When the black screen time of the mobile terminal 100 in the black screen state is greater than or equal to the preset second threshold, it is judged whether the current running state of the mobile terminal 100 satisfies the preset condition. Further, when the black screen time of the mobile terminal 100 in the black screen state is less than the preset second threshold, continue to calculate the black screen time of the mobile terminal 100, and determine whether the black screen time of the mobile terminal 100 is greater than or equal to the preset second threshold.

In this embodiment, when the mobile terminal 100 does not enter the black screen state from the bright screen state for the first time after starting up, it is determined whether the black screen time of the mobile terminal 100 is greater than or equal to the preset second threshold, and the preset second threshold is less than the preset first threshold. threshold. Only when the black screen time is greater than or equal to the preset second threshold, is it judged whether the current running state of the mobile terminal 100 satisfies the preset condition. Realized that when the mobile terminal 100 does not enter the black screen state from the bright screen state for the first time after starting up, the preset second threshold is set to be smaller than the preset first threshold, which improves the mobile terminal 100 when it is not the first time from the bright screen state to enter the black screen state , the speed at which the mobile terminal 100 enters the dormant state saves the power of the mobile terminal 100 .
