It is recorded in Base_CNT_A register.Further according to the sleep mechanism of principal communication Mode A, sleep/closing shape is obtained by calculation
The time value Wakeup_CNT that state needs to restore after terminating, it is subtracted each other with Base_CNT_A.It is reconverted into slow clock count
Count value, be saved into register Sleep_Time.F2Sratio is the frequency of main communication mode A fast clock and slow clock
Rate ratio.
Sleep_Time=(Wakeup_CNT-Latch_CNT_A)/F2Sratio

State begins preparing and completes being aligned for the fast clock of principal communication Mode A and slow clock, in S1 point the sleeping according to principal communication Mode A
Base_CNT and Sleep_Time is calculated (for example, if principal communication Mode A is 4G network, Sleep_Time in dormancy mechanism
Usually 1.28 seconds).The rising edge clock of slow clock is detected in S2 point, at this moment the fast clock of principal communication Mode A and slow clock pair
Together, the fast clock of principal communication Mode A stops, and slow clock starts counting, and until Sleep_Time, wakes up communication system.In this way
The purpose done is so that the fast clock frequency of communication pattern is the integral multiple of slow clock frequency, so as to accurately restore different
The time value of communication pattern.

Period, the orthochronous value for needing to restore；
Register Base_CNT (for example, register Base_CNT 502 shown in Fig. 5): principal communication Mode A is waken up extensive
Multiple orthochronous value；And
Register Reconstruct_CNT (for example, register Reconstruct_CNT_A 503 shown in Fig. 5 and/
Or Reconstruct_CNT_B/C 504): in the triggering of hardware reconstruction signal, current time value is saved in
In Reconstruct_CNT.
Fig. 6 shows the fast clock of DRX sleep awakening and slow clock alignment and the reconstruction of each embodiment according to the present invention
Time diagram.Reconstruction process is described in detail below with reference to Fig. 6:
Before principal communication Mode A is waken up from DRX sleep, what principal communication Mode A recovery time was counted as calculating before sleeping
Value Wakeup_CNT.
It is triggered in E1 point software reconstruction signal, generates principal communication Mode A and time communication pattern by △ Val to guarantee
The hardware reconstruction signal of B/C, the time value of two communication systems, which is synchronized to be saved in respective Reconstruct_CNT, at this time posts
In storage.Wherein △ Val is time interval, for guaranteeing the triggering of software reconstruction signal and then being rebuild.Assuming that
Reconstruct_CNT_A is the time value that main communication mode A passes through △ Val after E1 point, Reconstruct_CNT_B/C
The time value that restore is rebuild for secondary communication mode B/C, calculation method is as follows: Reconstruct_CNT_A=Wakeup_
CNT+ △ ValReconstruct_CNT_B=Latch_CNT_B+B_Time+ △ Val
Wherein, the calculation method of B_Time is as follows: Sleep_Time*F2Sratio is the sleeping time of main communication mode A,
The format differences calculated again by the time of principal communication Mode A and time communication mode B/C, are converted into time communication mode B/C
Sleeping time, that is, B_Time.
Since the value of the register Reconstruct_CNT of two communication patterns is rebuild under synchronization,
It is considered that two communication patterns of the moment are time synchronizations.The two can pass through Sleep_Time counter of slow clock
Value.Wherein, identical as latching process by the way of, that is, principal communication Mode A and the time counter of time communication mode B/C are
In E2 point rising edge alignment, next counting is started simultaneously at, to improve the time precision of reconstruction.
