Below in conjunction with describing technical scheme of the present invention in detail with Fig. 3 above.
1, GPS function (being position acquisition module) opens and closes
Processor 302 opening and cutting out by GPS module switch signal controlling GPS module 306.
2, GPS signal to noise ratio
Signal to noise ratio is defined as the ratio of available signal power and noise power in the GPS air interface signals that receiver front end measures, and is called for short SNR, i.e. SNR=PS/PN, and wherein, PS is gps signal power, PN is noise power.
Under equal positioning accuracy request, GPS signal to noise ratio is larger, locates sooner, and system is got over power saving.On the contrary, when GPS signal to noise ratio is less than certain value, locate very slowly, even cannot locate, can not meet user's requirement of real-time.
The too low main scene of GPS signal to noise ratio has: indoor, tunnel, building thick and fast, sleety weather etc.
Gps antenna receives gps signal and the ambient noise signal of satellite launch, send GPS chip (not shown) to, GPS chip calculates signal to noise ratio snr, be stored in the middle of the register of GPS chip, processor 302 reads the SNR value of storing in the middle of GPS chip register, is stored in memory 314.
3, translational speed
Translational speed is used for characterizing the speed of user's current time motion of carrying mobile terminal, refers to the speed measuring by GPS in the present invention, and the process that tests the speed is as follows:
Gps antenna 308 flows to GPS module 306 by the gps signal receiving, and GPS module 306 is processed into the gps signal of receiving can flow to processor 302 for the form of processor 302, and processor 302 calculates position coordinates A.After elapsed time T, again calculate position coordinates B.Distance between processor 302 coordinates computed A and coordinate B, divided by time T, obtains translational speed information.
4, positional information obtain and positional information obtain frequency
The software of processor operation is divided into bottom software and upper layer software (applications), and the gps signal that bottom software sends according to GPS module 306 calculates gps coordinate, flows to upper layer software (applications); Upper layer software (applications) woke up according to the time interval of timer, and received the gps coordinate from bottom software, then in addition processes and displays on display screen LCD.Operation when upper layer software (applications) is timed device and wakes up, all the other times, in resting state, are saved system power dissipation.The time interval that gps coordinate is obtained writes timer, and upper layer software (applications) just obtains position coordinates according to the time interval writing, and acquisition time interval is longer, obtains frequency slower, and upper layer software (applications) is longer in the time of dormancy, and system is got over power saving.This timer is just called position acquisition frequency timer.
5, acceleration
Most Integrated Accelerometer 304 in intelligent terminal, for the percentage speed variation in a certain moment of acquisition terminal, is called for short acceleration.The acceleration of acceleration transducer 304 on can tri-independent, direction of perception XYZ.Processor 302 reads the acceleration in tri-directions of XYZ of acceleration transducer 304 perception.
6, mobile cellular cell base station identifier Cell-ID
Mobile terminal is determined its position by gathering the cell base station identifier Cell-ID of its registration.As long as system can inquire by Cell-ID the geographical location information of base station, just can locate.The precision of location depends on the covering radius of community, and as in areas of Beijing, base station density is higher, and positioning precision can reach 200 meters of left and right; And in suburb, base station density is lower, positioning precision can only reach one or two kilometer.This technology realizes simple, and input cost is little, is most widely used location technology in wireless network at present.In the situation that there is no GPS, also can Primary Location by Cell-ID.
And the number of times changing within a period of time by collection Cell-ID (being the change frequency of the base station of terminal access) is as terminal parameter information.
Wherein, mobile terminal receives cell base station signal by radio-frequency antenna 312, after radio-frequency module 310 is resolved, sends the radio-frequency information that comprises Cell-ID to processor 302, and processor 302 therefrom takes out Cell-ID, is stored in memory 314.
Particularly, the present invention is defined as indoor mode and outdoor pattern by user's behavior pattern, and is subdivided into stationary indoors pattern, indoor Walking Mode, outdoor still-mode, outdoor Walking Mode, outdoor running modes and outdoor pattern by bus.
Wherein, indoor mode refers to the pattern of people in building time of using terminal, and stationary indoors pattern refers to indoor mode when people's movement velocity is less than 0.3km/h; Indoor Walking Mode refers to indoor mode when people's movement velocity is greater than 0.3km/h.
Pattern when outdoor pattern refers to the environment of people beyond building that uses terminal.
Outdoor pattern when people rides public transportation means, is defined as outdoor pattern by bus;
When people does not ride public transportation means when outer: when movement velocity is less than 0.3km/h, outdoor mode-definition is now outdoor still-mode; When movement velocity is greater than 0.3km/h and is less than 5km/h, outdoor mode-definition is now outdoor Walking Mode; When movement velocity is greater than 5km/h, outdoor mode-definition is now outdoor running modes.
