Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with each reality of the accompanying drawing to the present invention
The mode of applying is explained in detail.However, it will be understood by those skilled in the art that in each embodiment of the invention,
In order that reader more fully understands the application and proposes many ins and outs.But, even if without these ins and outs and base
Many variations and modification in following embodiment, can also realize the application technical scheme claimed.
The first embodiment of the present invention is related to a kind of acquisition methods of positional information.The acquisition methods of the positional information can
To use in the terminal, terminal mentioned here can for mobile phone, panel computer, wearable electronic equipment etc., below with
Illustrated exemplified by mobile phone.Fig. 1 gives a kind of flow of the acquisition methods of positional information, specifically includes：
Step 101, the request for obtaining position is received.
Specifically, the extensive application installed in terminal is required for obtaining the positional information of the terminal, such as：Shopping application
(Taobao, Jingdone district etc.), digital map navigation applies (Baidu map, Google's Google Maps, high moral map etc.), is obtained when starting needs
When taking the application of terminal positional information, the request for obtaining position can be sent, when such a request is received, into step 102.
Step 102, state is presently according to terminal, judges whether to need to directly invoke system position update module acquisition
Positional information.If it is, into step 103；Otherwise, into step 104.
For example, terminal is presently in state and can refer to terminal being currently at motion state or inactive state, at end
When end is currently at motion state, judgement needs to directly invoke system position update module acquisition positional information；It is current in terminal
When remaining static, judgement need not directly invoke system position update module and obtain positional information.Motion mentioned here
State can be that people's carried terminal is walked, run or by bus, and inactive state can be that terminal is stood somewhere, and this can be with
Judged by the acceleration transducer and gyroscope of terminal built-in, existing determination methods are used equally for this embodiment party
Formula, will not be repeated here.
Again such as, terminal, which is presently in state, can also refer to terminal (such as 5 before current time and prefixed time interval
Before second) a certain moment between whether the displacement in occurred level direction, if so, then judging to need to directly invoke system position renewal
Module obtains positional information；If it is not, then judging that need not directly invoke system position update module obtains positional information.This
, it is necessary to calculate in prefixed time interval terminal by the acceleration transducer and gyroscope of terminal built-in in level side under situation
To displacement, also there are many methods to carry out the calculating in the prior art, will not be repeated here.
Certainly, the application should not be exemplified as limiting with above-mentioned, any to be presently in state according to terminal, be made whether to need directly
The determination methods for connecing calling system location updating module acquisition positional information all should be within the protection domain of the application.
When judging to need to directly invoke system position update module acquisition positional information, into step 103, directly invoke
System position update module obtains positional information, and calling system location updating module is obtained after positional information, into step 105.
When judging that need not directly invoke system position update module obtains positional information, into step 104, system is read
Newest positional information in the caching of system position.
System position caches the positional information obtained for calling system location updating module before storage, the positional information
Can the time including acquisition positional information, the longitude and latitude of positional information, the requirement update mode (GPS/WIFI/ of positional information
Mobile base station) and GPS/WIFI/ mobile networks signal condition etc..Wherein, GPS signal condition is the satellite number searched
Amount, WIFI signal condition are that WIFI signal intensity, the signal condition of mobile network are mobile network signals intensity.Can in application
Can require update mode be GPS, but system call GPS update after, gps satellite can not be searched in the given time, then,
Other manner such as WIFI can be used instead and mobile base station obtains positional information.These positional informations are preserved to be conducive to deciding whether to adjust
Whole system position next time updates actually used update mode, such as last application requirement for several times needs to use GPS modes more
New position, but system does not search out satellite, actually uses WIFI and mobile base station positioning, and this several times location updating when
Between be spaced it is little, then illustrate that policy module will determine that and currently is not suitable for using GPS location, apply that to send GPS again fixed next time
During the request of position, policy module can not use GPS location, and directly be positioned using WIFI and mobile base station, so as to save
The power consumption produced because starting d GPS locating module.
What deserves to be explained is, system position caching can only cache a positional information, i.e., last system position updates
Module obtains the newest mobile status information obtained after positional information.System position caching can also cache certain time model
Interior positional information is enclosed, such as caches the positional information within a hour.System position caching can be with buffer some amount
Positional information, such as altogether can cache 10 positional informations, this 10 positional informations according to caching order respectively with compile
Number 1 to 10 represents, numbering 1 represents oldest positional information, and the newest positional information of the expression of numbering 10 expires 10 positions being cached to
After confidence breath, when new positional information is called in application again, has new positional information to need caching, it is 1 to remove numbering
It is exactly oldest positional information, newest positional information to reach one, is successively by remaining each position information encoding to number
10 are cached.But be not limited to here for example, technical staff can according to actual needs flexible design system position delay
Deposit.
In addition, it is noted that reading positional information newest in the caching of system position, newest position mentioned here
Confidence breath can be the last positional information got or the last position for calling GPS module to obtain letter
Breath (it is, the last time is accurately positioned obtained positional information).But the application should be not limited to here for example, technology
Personnel can flexibly specify newest positional information according to actual needs.
Step 105, positional information is fed back to the requesting party for obtaining position.
That is, being presently in state according to terminal, if it is decided that need to directly invoke system position update module and obtain
Positional information is taken, then directly invokes system position update module and obtains positional information；If it is determined that system need not be directly invoked
Location updating module obtains positional information, then newest positional information feeds back to the request for obtaining position during system position is cached
Side.Requesting party mentioned here can be the application that any one needs to obtain positional information in terminal.
Compared with prior art, the acquisition methods for the positional information that present embodiment is provided, are obtained by being received in terminal
During the request that fetch bit is put, state is presently according to terminal, judges whether to need to directly invoke system position update module acquisition
Positional information, and when system position update module need not be directly invoked, read position newest in the caching of system position
Information, is not to obtain positional information each time all to directly invoke system position update module, reduction directly invokes system position more
The number of times of new module so that the power consumption in the renewal process of system position is minimized, and then the power consumption of terminal is saved, extension is eventually
The cruising time at end.
Second embodiment of the present invention is related to a kind of acquisition methods of positional information.Present embodiment is implemented first
Further improvement has been done on the basis of mode, has specifically been theed improvement is that：Needing to directly invoke system position in present embodiment
In the case of putting update module, further determine whether to need real-time update, when needing real-time update, reduction, which is directly invoked, is
The frequency for location updating module of uniting so that the number of times of calling system location updating module, reduction are reduced during real-time update
Power consumption in the renewal process of system position, and then the power consumption of terminal is saved, extend the cruising time of terminal.Particular flow sheet
As shown in Fig. 2 it includes：
Step 201, the request for obtaining position is received.
Step 202, state is presently according to terminal, judges whether to need to directly invoke system position update module acquisition
Positional information.If it is, into step 203；Otherwise, into step 204.
It should be noted that the state that terminal is presently in is obtained, can be real using the acceleration transducer of terminal built-in
When monitor terminal exercise data, and exercise data is analyzed, it is determined that being obtained from last calling system location updating module
Whether terminal is moved through after obtaining positional information.Wherein, state is presently according to terminal, judging whether that needs are directly invoked is
Location updating module of uniting obtains positional information, specifically includes：Position letter is being obtained from upper once calling system location updating module
When terminal is not moved through after breath, judgement need not directly invoke system position update module；From upper once calling system
When terminal is moved through after location updating module acquisition positional information, judgement needs to directly invoke system position update module.
Such as, it is determined that whether being moved from terminal after last calling system location updating module acquisition positional information
Cross, can be realized by function of passometer of the prior art.If obtaining position from last calling system location updating module
Confidence was ceased into this period of time of current time, and the step number that pedometer is shown is 0, then it represents that terminal is not moved within the period
Moved.If the step number that pedometer is shown is more than or equal to predetermined threshold value, then it represents that terminal is moved through within the period.In addition,
The step number shown due to pedometer represents that terminal is moved through within the period more than or equal to predetermined threshold value, therefore can pass through
The max-thresholds of pedometer meter step are set, when reaching max-thresholds, step function are closed (in particular to the acquisition of positional information
Step function in method, does not influence other application), further save terminal power consumption amount.
Again such as, if terminal is moved in vehicles such as automobiles, it is determined that from upper once calling system position
Update module obtain positional information after terminal when whether moving, it is possible to use the acceleration transducer of terminal judge it is mobile away from
From if obtaining positional information displacement into this period of time of current time Zi last calling system location updating module
In preset value, then it represents that the terminal is not moved through.If displacement is more than or equal to the preset value, then it represents that the terminal is moved
Moved.Similarly, in order to further save terminal power consumption amount, max-thresholds can be set for displacement, closing measures movement
The function of distance.
In practical application, it is determined that from last calling system location updating module obtain positional information after terminal whether
Be moved through, can by way of flag bit is set it is convenient subsequently judge whether to need to directly invoke system position update module obtain
Take positional information.Such as, if terminal does not have after positional information is obtained from upper once calling system location updating module
It is moved through, then it is 0 to set flag bit；If the terminal after positional information is obtained from upper once calling system location updating module
It is moved through, then it is 1 to set flag bit.When judging whether to need to directly invoke system position update module, mark is directly read
Position.
Step 203, judge whether to need real-time update.If using real-time update is not needed, into step 206；Such as
Fruit application needs real-time update, then into step 205.
Specifically, whether real-time update is needed on application, can be being asked when application sends the request for obtaining position
To ask identify whether in message and need real-time update, such as, when navigation, map, the application of sport health class send solicited message, mark
Need real-time update；And during as the application transmission solicited message such as shopping, browser, mark does not need real-time update.Pass through parsing
Request message just would know that whether the application for sending request needs real-time update.
Step 204, positional information newest in the caching of system position is read.The newest position in system position caching is read
After confidence breath, into step 207.
Step 205, the frequency of calling system location updating module is adjusted according to real-time update demand.
Specifically, calling system location updating module can be adjusted according to the mobile state of terminal information of system cache
Frequency, can start with terms of the current translational speed of terminal and the required positioning precision two of application, adjustment calling system position
The frequency of update module.
Such as, can be according to the current translational speed of terminal, the frequency of calling system location updating module.First can be with
Rule of thumb data draw acceleration rate threshold scope of the terminal in usage scenarios such as walking, running, drivings, by walking, run, open
Car sets basic, normal, high Three Estate successively.Start to run after user starts an application of running, met during running
When needing to stay for some time to an event, terminal can adjust calling system according to the mobile state of terminal information of system cache
The frequency of location updating module, i.e., when speed by middle grade to inferior grade when, reduce application requirement renewal frequency, application call
System position update module can incoming requirement renewal frequency parameter, without user forgotten pause run application, Huo Zheyong
In the case that running application has been suspended at family, running application is still frequently requiring system position renewal.
Say for another example, can be according to using required positioning precision, the frequency of calling system location updating module.Precision will
Two grades of height can be divided into by asking：The high application of required precision such as thud, happy run circle running class application, Baidu, high moral etc.
Map class application, the social class application such as wechat, footpath between fields footpath between fields, be hungry, the location Based service class application such as drop drop；Required precision is low
The application such as electric business such as Taobao, Jingdone district class application；If required precision is low, renewal frequency is reduced, wherein, required precision is low
Positioned using WIFI or mobile base station can be used.
Step 206, directly invoke system position update module and obtain positional information.
If that is, when application needs real-time update, adjusted according to the mobile state of terminal information of system cache
The frequency of whole calling system location updating module, calling system location updating module obtains positional information；If be not required in application
When wanting real-time update, direct single call system position update module obtains positional information.
Step 207, positional information is fed back to the requesting party for obtaining position.
In addition, in order to further save terminal power consumption amount, can be in calling system location updating when needing real-time update
Module obtains the gap of positional information, and the positional information and terminal obtained according to last calling system location updating module is worked as
Preceding translational speed, calculating simulation value feeds back to the requesting party for obtaining position as positional information.
For example, during being driven using navigation, navigation application is sent for every 1 second obtains asking for positional information
Ask, it is not necessary to the positional information that all feedback calling system location updating module was obtained in every 1 second.Because automobile is generally according to pre-determined route
Traveling, therefore, it can the traveling speed with automobile currently according to the positional information of last calling system location updating module acquisition
Degree and direction, the current position of estimation automobile.It is possible to reduce the frequency of calling system location updating module, such as, and every 5
The positional information of second calling system location updating module acquisition simultaneously feeds back to navigation application, the middle then position of feedback estimation.Often
Precise position information is got every 5 seconds system position update modules, even if the middle positional information using estimation, nor affects on and leads
Navigate the Consumer's Experience applied.
Because step 201 is to step 202 in present embodiment, step 204 and step 206, step 207 and embodiment one
Middle step 101 is roughly the same to step 105, when terminal receives the request for obtaining position, is presently according to the terminal
State, judges whether to need to directly invoke system position update module acquisition positional information, need not directly invoke system position
When putting update module, positional information newest in the caching of system position is read, the requesting party for obtaining position is fed back to, herein no longer
Repeat.
Compared with prior art, the acquisition methods for the positional information that present embodiment is provided, are needing to directly invoke system
In the case of location updating module, further determine whether to need real-time update；If not needing real-time update, direct single is adjusted
Positional information is obtained with system position update module；If desired real-time update, then adjust calling system according to real-time update demand
The frequency of location updating module, and with the frequency after adjustment, calling system location updating module obtains positional information, judged whether
Need real-time update, it is to avoid in the case of unnecessary, using it is frequent obtain system position and update cause in real-time update mistake
The power consumption in the number of times of calling system location updating module, reduction system position renewal process is reduced in journey, and then is saved eventually
The power consumption at end, extends the cruising time of terminal.
Third embodiment of the invention is related to a kind of acquisition methods of positional information.Present embodiment is in the first embodiment party
Further improvement has been done on the basis of formula or second embodiment, has specifically been theed improvement is that：In the present embodiment, current
In the indoor or vehicles or weather is not good, when having using GPS location is asked again, reduction passes through GPS location
Frequency or directly positioned using WIFI and mobile base station, can further save the power consumption of terminal, extension terminal it is continuous
ETS estimated time of sailing.Particular flow sheet is as shown in Figure 3.
Step 301, the request for obtaining position is received.
Step 302, judge to cross GPS location with the presence or absence of continuous several times application request and can not be pre- in the caching of system position
If getting positional information in the time.If there is continuous several times application request in the caching of system position crosses GPS location and can not
Positional information is got in preset time, then into step 303；If there is no continuous several times application to ask in the caching of system position
Sought GPS location or positional information is got in preset time, then into step 304.
By judging to cross GPS location with the presence or absence of continuous several times application request in the caching of system position and can not be when default
It is interior to get positional information, it can be determined that whether terminal is currently in the indoor or vehicles or weather is not good.Such as
There is continuous several times application request in the caching of fruit system position to cross GPS location and position letter can not be got in preset time
Breath, then judge that terminal is currently in the indoor or vehicles or weather is not good；Otherwise, it is determined that terminal local environment is just
Often.
Step 303, the frequency of calling system location updating module is reduced.
Wherein, the frequency of calling system location updating module is reduced, can be realized by program timing, the tune being reduced to
The length of timing can be set to system position update module frequency.Such as, the time length to program timing is one
Minute, certain called primary system location updating module to obtain positional information using one second, but in the mistake for obtaining positional information
There is continuous several times application request in Cheng Zhong, system position caching to cross GPS location and do not got position within one minute
Information, then reduce the frequency of calling system location updating module, called primary system location updating module to obtain by each second
Positional information be changed to each minute call primary system location updating module obtain positional information so that be conducive to save terminal consumption
Electricity.
, can also be directly using WIFI and/or mobile base in addition to reducing the frequency of calling system location updating module
Stand and obtain positional information.Mobile base station positioning is generally used for cellphone subscriber, and mobile base station positioning service, which is called, does shift position
Service (LBS --- Location Based Service), it is obtained by telecommunications mobile operator network (such as GSM nets)
The positional information (latitude and longitude coordinates) of mobile terminal user, under the support of electronic map platform, provides the user respective service
A kind of value-added service, mobile phone location is determined to the measuring and calculating distance of the distance of mobile phone using base station, although precision very great Cheng
Degree is dependent on the distribution of base station and the size of coverage, and error can be more than one kilometer；WIFI positioning is location service provider
(such as Baidu, Google) is positioned based on WIFI hot spot to equipment, but for GPS location, WIFI positioning and movement
Architecture power consumption is less, can save significantly on system position and update power consumption, and then save terminal power consumption amount.
Step 304, judge whether to need to directly invoke system position update module acquisition positional information.If it is, entering
Enter step 306；Otherwise, into step 305.
Step 305, positional information newest in the caching of system position is read.
