Description
Technical field
The present invention relates to a kind of electricity saving method of GPS module.
Technical background
Universal day by day along with location-based service (LBS), the GPS module progressively becomes the indispensable configuration of middle and high end mobile phone.In position information applications such as navigation, monitoring, the GPS module becomes the main tool that mobile phone obtains positional information, and it has the high advantage of positioning accuracy, has irreplaceable status in this field.Yet, in the actual use of GPS mobile phone, must provide the common function that has with other type mobile phone simultaneously, as functions such as conversation, short message service, online.Therefore, a large amount of power consumptions the during work of GPS module just become the extra spending of GPS mobile phone, and power consumption is excessive to make obviously reduce the service time of battery of mobile phone.Become gradually under the environment of bottleneck in current battery capacity expansion, can't solve the excessive problem of mobile phone power consumption by increasing substantially battery capacity, so can only set about from this link of joint source.Need a kind of effective GPS module electricity saving method, thereby make under the situation that battery capacity does not change, GPS mobile phone and non-GPS mobile phone do not have too big gap service time.
Whether present existing power conservation techniques mainly is to adopt to detect to move in the use of GPS mobile phone to determine whether entering resting state, and promptly when the GPS mobile phone did not surpass the displacement of a fixed threshold, its GPS module was in non operating state; If there is significantly the position move, surpassed the fixed threshold of regulation, then activate the GPS module again, make it in running order.This mode can dynamically determine the open and close of GPS module, but depends on the size of the threshold value of defined to a great extent.And if the user in use is in the mobile status above threshold value always, then the method does not still reach any power saving effect.
Summary of the invention
At the problem of above existence, the present invention will propose a kind of electricity saving method of GPS module, with solving the problem that power consumption in the GPS operating handset process causes battery to reduce significantly service time too greatly.
A kind of electricity saving method of GPS module, when the GPS module located effectively and the GPS module operating time not overtime, then preserve this moment GPS information and dominant base information, allow the GPS module enter sleep state; Begin to judge whether dominant base information changes, variation has taken place, then start the GPS module, allow it enter operating state when mobile phone terminal detects dominant base information; If any variation does not take place dominant base information and GPS module location last time is effective, then the GPS module continues to keep sleep state; If any variation does not take place dominant base information and GPS module location last time is invalid, base station information does not change always and the duration surpasses threshold value if mobile phone terminal detects, and then starts the GPS module once more.
The electricity saving method of a kind of GPS module of the present invention, the booster action by the location, base station in the course of work of cellphone GPS module, detects the peripheral base station change in information in real time, controls the operating state of GPS module to reach intermittently, thereby reaches the effect of power saving.
Embodiment
The electricity saving method of a kind of GPS module of the present invention, at first, the work period that the GPS module is set in mobile phone terminal is M, and the farm labourer of GPS module in a work period is N as the time, and the scan period of base stations detected information change is L, wherein M>N; Behind the mobile phone terminal system initialization, start GPS module work period scanner and GPS module operating time scanner respectively, start the GPS module simultaneously, allow it enter operating state, this moment, the GPS module started for the first time;
Specifically may further comprise the steps:
If step 1 GPS module has been located effectively and the GPS module operating time is not overtime, then preserve this moment GPS information and base station information, close the GPS module, GPS module operating time scanner stops scanning, jump procedure 3 simultaneously;
Step 2, overtime as if the GPS module operating time, close the GPS module immediately, invalid GPS information and base station information are this moment uploaded to the positioning service center by cordless communication network, the base station information of being uploaded according to mobile phone terminal by the positioning service center carries out the location, base station, and the positional information that obtains is returned to mobile phone terminal offers upper level applications as this positional information;
Step 3, when treating that the GPS module work period expires, base station information that GPS module was this moment got access in the work period and the base station information that is obtained during the location in the last GPS module work period compare, if it is consistent, whether then detect last time GPS location effective, if effectively then the positional information of last time is designated as this positional information, execution in step 3 then circulates; If the GPS of last time location is invalid, then start the base station information scanner, skip to step 4; If the base station information that is obtained when locating in base station information that gets access in the Current GPS module work period and last GPS module work period is inconsistent, confirm that then the base station information scanner is out of service, and start GPS module operating time scanner and GPS module, skip to step 1;
Step 4, overtime as if the work of base station information scanner then starts GPS module operating time scanner and GPS module simultaneously, skips to step 1.
Just because of the booster action of location, base station, can help mobile phone terminal to judge the range size that mobile phone terminal moves in the GPS module routine.If variation has taken place in the dominant base information that gets access to of mobile phone, prove that then the scope that mobile phone moves is big slightly, for obtaining position more accurately, then start the GPS module, allow it enter operating state; If any variation does not take place the dominant base information that gets access to of mobile phone and GPS locate effectively last time, prove that then the mobile phone moving range can calculate in the error range of permission, the GPS module then continues to keep sleep state so; If the dominant base information that gets access to of mobile phone do not take place any variation and GPS located last time invalid, then starting a scanner scans the GPS positioning states, if base station information does not change in the scan period always, device work then to be scanned starts the GPS module once more when overtime.
Spirit of the present invention is: when the GPS module located effectively and the GPS module operating time not overtime, then preserve this moment GPS information and base station information, allow the GPS module enter sleep state; Begin to judge whether dominant base information changes, variation has taken place, then start the GPS module, allow it enter operating state when mobile phone terminal detects dominant base information; If any variation does not take place dominant base information and GPS module location last time is effective, then the GPS module continues to keep sleep state; If any variation does not take place dominant base information and GPS module location last time is invalid,, then start the GPS module once more if the detected base station information of mobile phone terminal does not change and surpass threshold value always.
