Method, system and mobile terminal.
Background technology
Mobile terminal is in addition to basic communication function, because the accurate timing of its time, shows clear, is also much used
Electronic tool of the family as the time that is to look at；In the prior art, the time of mobile terminal is to mobile whole according to its counter
End master clock count and then along with an accurate basal latency obtains current time, specific as follows：
When mobile terminal correction time, the value of counter is P1, and the time that should currently correct is K1；After correction is finished, count
Device P1 can add 1 in each mobile terminal master clock cycle, if master clock cycle is T1, then when the value of counter is P2,
The time K2 of mobile terminal should be：
K2=K1+（P2-P1）* T1.
Counter in current mobile terminal is often definitely enough, and a century can be used by typically counting from zero；
But the features such as being due to the portability of mobile terminal, mobile terminal it is unavoidable in routine use because electrostatic, magnetic field in environment,
Fall or the factor such as chip quality problem surprisingly causes the value of counter to be changed；When the value of counter is surprisingly changed first
Occur be exactly mobile terminal time it is incorrect, now user can pass through network or manual correction time；But when counter
Value by it is unexpected be revised as close to the value of spilling when, when user by network or manual correction time uses some time（May be very
It is short such as one hour, may be very long such as 5 years）The secondary display mistake of time can be caused because of counter overflow again afterwards, to use
Bring puzzlement at family, or even delays the thing of user.
I.e. in the prior art for example, the value of counter because the electrostatic in environment, magnetic field, fall or chip quality problem etc. because
Element is surprisingly revised as P3, and P3 and counter maximum P4 closely；When user's discovery time is incorrect, pass through
Network or manual correction time, but the value of counter can be reached after maximum P4 after counter overflow again after a period of time
Become zero；Now because the value of counter becomes zero and can cause a time showing mistake, puzzlement is brought to user, or even indulge in
Misapply the thing at family.
Therefore, prior art has yet to be improved and developed.

Embodiment
To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and without
It is of the invention in limiting.
Fig. 1 is referred to, Fig. 1 is the flow of the preferred embodiment of the method for time correction control of the invention based on mobile terminal
Figure.As shown in figure 1, the method for time correction control based on mobile terminal described in the embodiment of the present invention, comprises the following steps：
S100, mobile terminal starts value of the timer every the time detecting counter of setting, and compares the value of counter with setting
The size of fixed thresholding；
Specifically, the thresholding of the setting, it is preferred that being the 80% of counter maximum P4, such as counter of mobile terminal
Maximum count value P4 is stored in the register of one 16, then P4 maximum count value subtracts 1 for 2 16 powers, then sets
Thresholding is preferably（2 16 powers subtract 1）80%.
The timer, its time-out time is counter maximum P4* clock frequencies * 10%, for example, mobile terminal
Master clock frequency is 100000000Hz, and counter maximum count value P4 is stored in the register of one 16, then P4 maximum
Count value subtracts 1 for 2 16 powers, then the time-out time of timer is set to（2 16 powers subtract 1）With 100000000 product
10% ；
Further, step S100 comprises the following steps：
Start timer；
The value of detection counter when the timer expires；
Compare the value and the size of the thresholding of setting of counter.
S200, when the value of counter is more than the thresholding of setting, acquisition current time is K；
When the value of counter is more than the thresholding of setting i.e. in the present invention（The thresholding for example then set is preferably（2 16 powers subtract
1）80%）When, acquisition current time is K, and such as 11.00 is whole.
When counter value because of the electrostatic in environment, magnetic field, fall or when the factor such as chip quality problem is surprisingly changed
（It is greater than the thresholding of setting）, it is possible to prevente effectively from because the secondary time showing mistake that counter overflow is brought, is improved
The accuracy rate of time showing, so as to be user-friendly to.
The count value of such as mobile terminal in the specific implementation of the invention is stored in the register of one 16, currently should
The value of the register of 16 is 0000000000000011 (binary representation)；Then due to the electrostatic in environment, magnetic field, fall
Or the factor such as chip quality problem is surprisingly changed the value of the register of 16 and is modified to 0100000000000011 (two enter
Tabulation is shown).
Note：0000000000000011 (binary representation) is metric 3;0100000000000011 (binary form
Show) it is metric 16387
Obvious 3 differ greatly with 16387；If thresholding has exceeded thresholding for 16,000 16387.
In the present invention when the value of counter is more than the thresholding of setting, acquisition current time is K.
S300, resets the value of counter, and corresponding to current time K.
Specifically, by resetting counter, even if the value of counter is zero, then by the value of counter and step S200
The current time K of acquisition is carried out to should be used as new correction time；Like this, it is mobile subsequently when the value of counter is P2
The time K2 of terminal should be K2=K1+（P2-P1）* T1；Wherein, T1 is master clock cycle, P1 be after resetting in step S3 with
The corresponding count values of time K（Namely zero）, K1 is K.
For example：Assuming that master clock cycle T1 is 0.001 second, if the current time K obtained in step S200 is 199.99 seconds,
The value P1 of this hour counter is 0（P1 be step S3 in reset after count value corresponding with time K, that is, zero）；Will be current
Time K is carried out to should be used as new correction time, i.e. K1=K=199.99 second;
When the time a moment later after, the value P2 of counter is 1000, and the time K2 of mobile terminal should be K2=K1+（P2-
P1）* T1=199.99 seconds+(1000-0) * 0.001 second=200.99 seconds.
Therefore, the invention provides a kind of method of time correction control based on mobile terminal, methods described passes through
Start value of the timer every the time detecting counter of setting, and compare the value and the size of the thresholding of setting of counter；When
When the value of counter is more than the thresholding of setting, acquisition current time is K；The value of counter is reset, and corresponding to current time K.
When counter value because of the electrostatic in environment, magnetic field, fall or when the factor such as chip quality problem is surprisingly changed, can be effective
Avoid because the secondary time showing mistake that counter overflow is brought, improves the accuracy rate of time showing, so as to facilitate user
Use.
