Serial ports on data transmission state, if the scheduled time as described in being detected in 500ms data transmission state be USB serial ports on
No data is transmitted, then discharges the clock sources on the serial ports, and controls when meeting preparatory condition the first application processor 10
Enter dormancy with the second application processor 20.
Whether there is the specific testing mechanism of data transfer as follows on serial ports：
Resource requirement is reported that RPM14 is according to each subsystem to resource to RPM14 by each subsystem of mobile terminal 1 00
Demand carries out comprehensive assessment, it is determined that the device for the consumption energy that can be closed and open, and perform corresponding control.Specifically
Ground, between the first application processor 10 and the second application processor 20 of dormancy control system, mainly carries out two by USB serial ports
Wake-up, state notifying and usb communication between individual application processor.

Sleep.If detecting no data transmission (function interface is not called upon) within the scheduled time such as 500ms, Serial Port Transmission agreement is called
The dormancy function carried such as USB_POWER_DOWN () function, it is that the resource discharged shared by serial ports includes to perform serial ports dormancy
Clock sources, now, corresponding modem could carry out dormancy.
It is the serial port drive of the first application processor 10 because clk1 is corresponding, clk2 corresponding is the second application processor
20 serial port drive, then, clk1 do not discharge can cause the first application processor 10 can not dormancy, clk2, which does not discharge, can cause
Two application processors 20 can not dormancy.Therefore, the control dormancy between the first application processor 10 and the second application processor 20
It is separate, not by other side's control, it is not required that other side votes, as long as above-mentioned condition is met, then performs respective
Dormancy control program.
Specific dormancy control sequence can be scheme as described below：
Because RPM14 controls four subsystems (application processor, modem, PRONTO and LPASS) resource,
All subsystems need to be applied to RPM14 when needing to use resource, then.Therefore, subsystems are not needing work
When, that is, the dormancy program of itself is performed, oneself dormancy is said to RPM14 ballots after subsystem dormancy.When four subsystems to
RPM14 has been thrown after dormancy ticket as above, and host CPU is closed in RPM14 decision-makings, while itself also dormancy, now whole system is into most
Low-power consumption.That is, dormancy control system is when control carries out dormancy program, modules enter the sequencing of dormancy successively
It is：Four subsystems, RPM14, CPU.It is understood that the above-mentioned scheduled time is not limited to the tool enumerated in the present embodiment
Body numerical value, can according to actual needs such as size parameter of the shapes and sizes of dormancy control system, data card and for changing
Become.It should be understood that due to be between the first application processor 12 and the second application processor 22 it is separate, not
By other side's control, therefore, detecting between the first application processor 12 and the second application processor 22 on USB serial ports
Data transmission state when, the controller can be the first application processor 12 or the second application processor 22.
Wherein, the first application processor 10 and the second application processor 20 include wake-up states and resting state.
The present invention is then controlled at the first application by monitoring that no data is transmitted on serial ports within the scheduled time such as 500ms
Manage the application processor 20 of device 10 and second and enter dormancy progress resting state.In this way, double LTE communication functions can be not only realized,
When no data transmitting-receiving such as breath screen state on serial ports can also be in dormancy control system, then start resting state, Ke Yiji
The earth reduces the power consumption of dormancy control system.
The present invention also provides a kind of dormancy control method of dormancy control system as described above, and reference picture 4 is real first

Dormancy control program.
Specific dormancy control sequence can be scheme as described below：
Because RPM14 controls four subsystems (application processor, modem, PRONTO and LPASS) resource,
All subsystems need to be applied to RPM14 when needing to use resource, then.Therefore, subsystems are not needing work
When, that is, the dormancy program of itself is performed, oneself dormancy is said to RPM14 ballots after subsystem dormancy.When four subsystems to
RPM14 has been thrown after dormancy ticket as above, and host CPU is closed in RPM14 decision-makings, while itself also dormancy, now whole system is into most
Low-power consumption.That is, dormancy control system is when control carries out dormancy program, modules enter the sequencing of dormancy successively
It is：Four subsystems, RPM14, CPU.It should be understood that due to the first application processor 12 and the second application processor 22
Between be separate, not by other side's control, therefore, detecting the first application processor 12 and the second application program
Between processor 22 during data transmission state on USB serial ports, the controller can for the first application processor 12 or
Second application processor 22.

Step S11, real-time or timing the first application processor 10 of detection and the respective USB serial ports of the second application processor 20
Driving；
Step S12, judge the respective USB serial port drives of 10 and second application processor of the first application processor 20,
Whether corresponding data transmit-receive function interface is called.
, can be according to the first application processor 10 and second in order to reduce the power consumption of dormancy control system in the present embodiment
The working condition of application processor 20, enters to determine the need for the first application processor 10 of control and the second application processor 20
Enter park mode., therefore, can due to being connected between the first application processor 10 and the second application processor 20 by USB serial ports
To be passed by the data on the USB serial ports between timing or the first application processor 10 of real-time detection and the second application processor 20
Defeated state determines whether dormancy.
The USB serial port drives of first application processor 10 and the second application processor 20, the letter received and dispatched with control data
Number.When needing transceiving data, the function need to only be detected by calling corresponding function interface, namely detecting the presence of data transmit-receive
Whether interface is called within a predetermined period of time.And the first application processor 10 and the second application processor 20 can be performed
The detection is operated because two modems be required to determine by this testing mechanism itself whether the carry out dormancy.
In the third embodiment, reference picture 6, on the basis of the second embodiment, the step S2 further comprises：
If step S21, detecting the respective USB serial ports of first application processor, 10 and second application processor 20 and driving
It is dynamic, do not transfer corresponding data transmit-receive function interface, then discharge the clock sources on the USB serial ports；
In the present embodiment, the USB serial ports between the first application processor 10 and the second application processor 20 is passed by serial ports
Defeated agreement defines serial ports dormancy mechanism, the dormancy function that the Serial Port Transmission agreement is carried such as USB_POWER_DOWN () function,
Support itself dormancy.If detecting no data transmission (function interface is not called upon) within the scheduled time such as 500ms, string is called
The dormancy function that port transmission agreement is carried such as USB_POWER_DOWN () function, it is shared by release serial ports to perform serial ports dormancy
