Abstract
The present invention discloses a method of updating CDMA network time on real time when the terminal steps over the time zone. The method includes the steps of: a timer which is positioned on the upper UI is initiated; the upper UI obtains the current network time from the bottom and stories the time when the time set by the timer is up; the current network time is compared with the local time, and if they are not accordant, the local time is then be updated. In the present invention, the disadvantage that error will occurs on the time displaying when the terminal steps over the time zone is overcome.
Description
Technical field
The present invention relates to the CDMA technology field, relate in particular to a kind of when the terminal cross time zone real-time update cdma network time method.
Background technology
CDMA terminal the time in time zone before the remaining of demonstration, does not refresh and is new time zone time after crossing over the time zone.And in fact the protocol layer time of high-pass platform be accurately always, this be because capture Sync Channel Message after will upgrade the bottom time.
The usually said upper strata time is that obtaining of protocol layer time is after starting up of terminal finds network, obtains the primary network time, adopts the mode of software timing to come show update time then.Therefore, the processing of just will starting shooting again, otherwise the time on upper strata and network time be actually independent process, so just cause behind the terminal cross time zone, the demonstration of time can make a mistake, time in time zone before the shown time of terminal remains.
At present the technical scheme that time showing adopted of CDMA terminal is to obtain behind the starting up of terminal primary network time, upgrades by the mode of software timing in this locality then and shows the current time.If terminal cross time zone and the processing of not starting shooting again, time showing obviously can't with network time synchronization.Therefore just need a kind of method to make terminal when crossing over the time zone, correctly show the cdma network time.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of when the terminal cross time zone real-time update cdma network time method, to overcome behind the terminal cross time zone shortcoming that the time showing of terminal can make a mistake.
For solving the problems of the technologies described above, the invention provides a kind of when the terminal cross time zone real-time update cdma network time method, comprise the steps:
(1) at upper strata UI a timer is set, and starts this timer;
(2) when time that timer is set then, upper strata UI obtains the current network time and preserves this time from bottom;
(3) described current network time and local zone time are compared,, then local zone time is upgraded if inconsistent.
Wherein, described step (3) also comprises, if the current network time is consistent with local zone time, then need not local zone time is upgraded.
Wherein, further comprise step (4), reset timer.
Wherein, in the described step (2), obtain the current network time by the mode of inquiry.
Wherein, whether described current network time and local zone time be consistent is meant whether the current network time is identical with local zone time.
Wherein, described local zone time is the network time of the upper strata UI last time obtaining and preserving.
Of the present invention a kind of when the terminal cross time zone real-time update cdma network time method, overcome the terminal shortcoming that time showing can make a mistake after crossing over the time zone.
Description of drawings
Fig. 1 be of the present invention a kind of when the terminal cross time zone block diagram of real-time update cdma network time method;
Fig. 2 is the schematic flow sheet of embodiment of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
With reference to figure 1, for of the present invention a kind of when the terminal cross time zone block diagram of real-time update cdma network time method.Specifically comprise the steps:
Step 110: at upper strata UI a timer is set, and starts this timer.When the UI task initialization, be provided with and start a timer.
Step 120: when time that timer is set then, upper strata UI obtains the current network time and preserves this time from bottom.
Common described system time is meant the second number of current time apart from global standards time UTC (Universal Time Coordinated, general universal time coordinated), and the shift time that this system time is added the time zone just can obtain current network time accurately.
Step 130: described current network time and local zone time are compared,, then local zone time is upgraded if inconsistent.
Described local zone time obtains the primary network time and it is kept at terminal inner when being meant starting up of terminal, the mode that adopts the software timing then is in local timing.
If consider the accumulated error of time zone problem and software timing, shown ground of the terminal time has inaccurate factor and exists.After current network time and local zone time compared, if the gained result then need not to upgrade consistent, if inconsistent, will upgrade local zone time.
As shown in Figure 2, be the schematic flow sheet of embodiment of the present invention.
Step 210 a: timer is set and starts this timer at upper strata UI.When the UI task initialization, start a time inquiry timer
Step 220: when time that timer is set then, upper strata UI obtains the current network time and preserves this time from bottom.
Upper strata UI initiatively goes to inquire about the current network time at regular intervals, obtains and preserve this time.The method of the invention can be divided by the time in time zone, promptly set every 30 minutes and initiatively went to inquire about.
Step 230: judge whether the described current network time is consistent with local zone time, if the replacement timer is also waited for timer expiry next time, enters step 150; If not, then enter step 140.The time difference of preserving when the time of determining inquiry and last time is greater than time of timer (as 30 minutes of setting), and the time of just thinking, variation took place, and upgraded local zone time and got final product.
Step 240: local zone time is upgraded.Described local zone time is the network time of the upper strata UI last time obtaining and preserving
Step 250: replacement timer.
The present invention is to solve the time error that CDMA terminal cross time zone causes, after terminal is carried out web search again, bottom can carry out the synchronous of system time after capturing Sync Channel Message, so the time of bottom is consistent with network time certainly.
Method of the present invention is by adopt the timer timing requester network time to guarantee the accuracy of time on the upper strata, upper strata UI initiatively goes to inquire about the current network time at regular intervals, after the inquiry current network time and local zone time are compared, then need not to upgrade as unanimity, inconsistently then will upgrade.The method of the invention can be used for the CDMA terminal of any a use high-pass platform, verifies on high-pass platform.
