Detailed description of the invention
The present invention provides a kind of method and system reducing location mobile device power consumption, for making the purpose of the present invention, technology
Scheme and effect are clearer, clear and definite, and the present invention is described in more detail below.Should be appreciated that described herein specifically
Embodiment only in order to explain the present invention, is not intended to limit the present invention.
Refer to the flow process that Fig. 1, Fig. 1 are a kind of method preferred embodiment reducing location mobile device power consumption of the present invention
Figure, as it can be seen, comprising:
Step S1, gathered the LBS position data of mobile device by LBS Module, and judge mobile according to described LBS position data
Whether equipment is in mobile status, if then entering into step S2；
Step S2, gathered the WIFI position data of mobile device by WIFI module, and sentence further according to WIFI position data
Whether disconnected mobile device is in mobile status, if time, then report WIFI position data.
For providing three modules of positional information: LBS Module, WIFI module, GPS module, power saving are LBS Module
(because system inherently needs to be connected with base station always, so almost it is believed that obtain LBS position data not power consumption, and obtain
Taking WIFI position data power consumption maximum, immediate current is about 50MA, but the persistent period only has about 1S, and GPS power consumption is electric
Stream is about 30MA, but the persistent period is long, sometimes all possibly cannot obtain GPS information up to 1MIN), based on this, determine
The priority of power saving strategy calling module is that LBS Module is the highest, is WIFI module the most again, is finally only GPS module.
For mobile device, every time report position data very power consumption by GPRS module, however static for equipment or
When person's equipment is in microinching state, repeatedly report same position information is nonsensical to server, so the present invention
When judging static (herein static is broad sense, also includes being in microinching state), an only position data of report.Experiment
Show, when reducing the motion of static or microinching, report frequency, power consumption greatly can be saved, (how to judge static shape
State, is described later, and this algorithm may determine that user is in mobile or resting state, there certainly exist user and is obviously in
Static state, but can report by mistake and be kept in motion, and (inspection of WIFI position data comes can to pass through secondary check this time
Realize).
Specifically, as in figure 2 it is shown, described step S1 specifically includes:
Step S11, read current LBS position data；
Step S12, the base station letter of the LBS position data that the base station information in current LBS position data and last time are reported
Breath compares, and obtains the most identical base station information；
Step S13, calculate in same base information corresponding signal intensity difference and, if described difference and less than the first threshold
Value, then judge that described mobile device remains static.
The present invention is by reading current LBS position data, thus obtains current base station information, then with on the last time
The base station information of LBS position data of report compares, specifically by current base station information with report server before
Base station information contrasts, and such as contrast has how many group base station information to be identical, if in such as two groups base station informations, and MCC,
MNC, LAC, CI are the most identical, are considered same base station information, and record twice with variable SameLBSItemNum and report
The quantity of same base information, say, that the LBS position data reported each time, comprises multiple base station information, the most current
Multiple base station informations and the multiple base station informations reported before.Record the most identical base station signal intensity difference and
(recording with LBSSignalLevelDeltaSum).
Such as: assume to report last time the base station information of position to have 5 groups, corresponding to (A1, A2, A3, A4, A5), these 5 groups of base stations
The signal intensity of information is respectively (S1, S2, S3, S4, S5)；This base station information reported by 6 groups (A1, A2, A4, A6, A7,
A8), corresponding signal intensity is (S6, S7, S8, S9, S10, S11).This means this base station information reported by 3 (A1,
A2, A4) identical when being the base station information taken with last time.
Then computational methods are as follows: SameLBSItemNum=3；
LBSSignalLeveDeltaSum=ABS (S6-S1)+ABS (S7-S2)+ABS (S8-S4), ABS () therein represents to be asked
Absolute value.
If this LBSSignalLeveDeltaSum is less than first threshold, illustrates that the change in location reported is little twice, can sentence
Fixed described mobile device remains static.
It addition, in the present invention, may also be combined with SameLBSItemNum and judge whether to remain static, such as
SameLBSItemNum is relatively big, then the two identical multiple base station information quantity of explanation are many, can directly judge to be in static shape
State, such as SameLBSItemNum are more than LBS amount threshold, then directly judge to remain static.And work as
When SameLBSItemNum is less than LBS amount threshold, judge that LBSSignalLeveDeltaSum is the least the most according to the method described above
In first threshold.
In order to prevent LBS position data sudden change and cause judge error, to LBS position data use continuous sampling and ask
Average mechanism, such as continuous sampling 4 groups, removes the highest minimum, is averaged to remaining two groups, uses meansigma methods the most again
Carry out above-mentioned algorithm calculating.
Through above method for designing, LBS Module judge the chance of success whether mobile device moves can be up to 90% with
On, mobile device power consumption can be effectively reduced, if LBS Module judges to be in mobile status, it is also possible to utilize WIFI mould
Block judges further.
Further, as it is shown on figure 3, described step S2 specifically includes:
Step S21, read current WIFI position data；
Base in step S22, the WIFI position data that the base station information in current WIFI position data and last time are reported
The information of station compares, and obtains the most identical base station information；
Step S23, calculate in same base information corresponding signal intensity difference and, if described difference and less than the second threshold
Value, then judge that described mobile device remains static.
In above-mentioned steps, carried out by current WIFI position data and the WIFI position data reporting server before
Contrast, is the most also that contrast has how many group base station information to be identical, and the MAC of focus is identical, is considered same base station letter
Breath, records the quantity of same base information with variable SameWiFiItemNum, and records two-by-two between same base information
The difference of signal intensity and (recording with WifiSignalLevelDeltaSum).
Such as: assume to report last time the base station information of position to have 5 groups, corresponding to (W1, W2, W3, W4, W5), these 5 groups of base stations
The signal intensity of information is respectively (WS1, WS2, WS3, WS4, WS5)；This base station information reported by 6 groups (W1, W2, W4,
W6, W7, W8), corresponding signal intensity is (WS6, WS7, WS8, WS9, WS10, WS11).This means this base station reported
Information has 3 (W1, W2, W4) identical when being the base station information reported with last time.
Then computational methods are as follows: SameWiFiItemNum=3；
WifiSignalLevelDeltaSum= ABS(WS6-WS1)+ABS(WS7-WS2)+ABS(WS8-WS4)。
If this WifiSignalLevelDeltaSum is less than Second Threshold, illustrate that the change in location reported is little twice, can
Judge that described mobile device remains static.
It addition, in the present invention, may also be combined with SameWiFiItemNum and judge whether to remain static, such as
SameWiFiItemNum is relatively big, then the two identical multiple base station information quantity of explanation are many, can directly judge to be in static shape
State, such as SameWiFiItemNum are more than WIFI amount threshold, then directly judge to remain static.And work as
When SameWiFiItemNum is less than WIFI amount threshold, judge that WifiSignalLevelDeltaSum is the most according to the method described above
No less than Second Threshold.
Cause judging error to prevent the sudden change of WIFI position data, WIFI position data is used the sum of continuous sampling
The mechanism being averaging, such as continuous sampling 4 groups, removes the highest minimum, is averaged to remaining two groups, the most again with average
Value carries out above-mentioned algorithm calculating.
Through above method for designing, WIFI judges that the chance of success that+LBS judges whether mobile device moves can be up to
More than 99% (not yet reach 100%, be because sometimes, some WIFI AP equipment can be shut down), can be very by the present invention
Effective minimizing calls GPS use frequency, reduces the purpose of power consumption.
Further, described step S2 also includes:
Step S20, judge whether described WIFI position data meets positioning precision demand, if meet, the most directly report WIFI
Position data, otherwise opens GPS module, obtains GPS location data by GPS module, and reports GPS location data.
This step is to judge whether WIFI position data meets positioning precision demand, if met, then without reporting
GPS location data, if being unsatisfactory for also needing to open GPS module, is positioned by GPS module.
Further, described step S20 specifically includes:
S201, the WIFI position data currently obtained is ranked up according to signal power；
S202, described WIFI position data is carried out filtration treatment；
S203, obtain the quantity of effective WIFI position data；
S204, quantity according to effective WIFI position data judge whether described WIFI position data meets positioning precision demand.
Specifically, the WIFI position data that will currently obtain, it is ranked up (on server according to signal intensity power
The best WIFI information of always signal passed), and carry out filtering and judge (remove the WIFI of the widest City-level of those coverage rates,
Such as CMCC etc.), the number of effective WIFI position data is recorded with ucValidWifiNum.Such as signal intensity is more than or equal to
During signal strength threshold, assert that this WIFI position data is the information that effectively positions.
Finally, judge according to quantity, such as, when ucValidWifiNum is not less than WIFI threshold value, assert this group
WIFI position data can meet the positioning precision demand of server.When meeting positioning precision demand, then need not open again
GPS。
