The structured flowchart of the mobile terminal that Fig. 2 provides for the embodiment of the present invention.
Embodiment
The invention provides a kind of based on motion state and adjust method and the mobile terminal of WIFI scanning frequency, clearer, clear and definite for making purpose of the present invention, technical scheme and effect, referring to accompanying drawing, developing simultaneously, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, it is to the present invention is based on the flow chart that motion state is adjusted the method for WIFI scanning frequency.As shown in Figure 1, the method for based on motion state adjustment WIFI scanning frequency of the present invention comprises:
S100, obtained the motion state information of mobile terminal by motion sensor.
S200, calculate the motion state of mobile terminal according to motion state information, and judge whether described motion state changes, when motion state changes according to the scanning frequency of the variation self adaptation adjustment WIFI module of motion state.
In step S100, described motion sensor comprises acceleration transducer, geomagnetic sensor and angular-rate sensor.Wherein, acceleration transducer is mainly used to detect the acceleration of mobile terminal on all directions.As being applied to the pedometer in smart mobile phone, it can obtain when the user walks and step how many steps.Described geomagnetic sensor is mainly used to obtain user's the direction of motion, as the application of digital compass.Described angular-rate sensor is for obtaining the variation of angular speed of motion, and auxiliarily Magnetic Sensor obtains the more accurate direction of motion.
In step S200, described motion state comprises movement velocity and the direction of motion, and the data that this movement velocity and the direction of motion are obtained according to above-mentioned three transducers are carried out the Treatment Analysis acquisition.When movement velocity or the direction of motion change, adjust the scanning frequency of WIFI module according to the variation self adaptation of motion state.
At first, calculate the motion state of mobile terminal according to motion state information in specific implementation process, described step S200 specifically comprises:; Then, by the contrast of motion state and predetermined movement state, judge whether described motion state changes; If judge that motion state is slack-off or accelerates; When motion state accelerates, accelerate the scanning frequency of WIFI module; When motion state is slack-off, reduce the scanning frequency of WIFI module.
Wherein, when motion state accelerates, also can directly the scanning frequency of WIFI module be adjusted to the highlyest, make it reach the requirement of WIFI scanning frequency with prestissimo; Correspondingly, when motion state is slack-off, also can directly stop the periodic scan of WIFI module, find new WIFI focus without accelerating scanning frequency, thereby save the power consumption of WIFI module, extend the cruising time of the mobile terminal under the WIFI mode of operation, improved user's experience.
For example, the threshold value of predetermined movement state is 10KM/h, and when movement velocity surpasses 10KM/h, its movement velocity is fast; Lower than 10KM/h the time, its movement velocity is slow.In movement velocity when accelerating slowly, mean that now environmental change is larger, limited coverage area due to a WIFI focus, need to be switched on other wifi focus, now require scanning frequency to accelerate, could find in time new WIFI focus, therefore need to accelerate the scanning frequency of WIFI module, perhaps directly scanning frequency is made as the highlyest, makes it directly enter the efficient operation pattern.When movement velocity is from fast to slow, now environmental change is little, network environment is constant, and now the user can use same WIFI focus online for a long time, does not need fast scanning frequency to remove to find new WIFI focus, therefore can reduce scanning frequency, to save the power consumption of WIFI module.
Further, in embodiment, before step S100, described method also can comprise: obtain the GPS information of mobile terminal by the GPS module, according to GPS information, judge that mobile terminal is indoor or outdoor.If outdoor, the user likely being driven, by bus, the activity such as take a walk, climb the mountain, now generally there is no the WIFI focus, therefore do not need to open the WIFI module, now can directly stop the periodic scan work of WIFI module.If mobile terminal indoor, judges whether the mobile terminal region has the WIFI focus, if do not stop the periodic scan of WIFI module, if any entering again step S100, carry out the judgement of motion state information.
Based on motion state based on above-mentioned is adjusted the method for WIFI scanning frequency, the present invention is also corresponding provides a kind of mobile terminal, as shown in Figure 2, it comprises WIFI module 10, motion sensor 20 and self adaptation adjusting module 30, and described WIFI module 10 is connected self adaptation adjusting module 30 with motion sensor 20.
Wherein, described WIFI module 10 is for obtaining the WIFI signal, and the sweep signal of these WIFI module 10 exportable predeterminated frequencies, find the WIFI focus.Described motion sensor 20 is for obtaining the motion state information of mobile terminal.Specifically as described in step S100.
Wherein, described motion sensor 20 comprises acceleration transducer, geomagnetic sensor and angular-rate sensor.Described motion state information comprises movement velocity and the direction of motion.
Described self adaptation adjusting module 30, for calculate the motion state of mobile terminal according to motion state information, and judge whether described motion state changes, and adjusts the scanning frequency of WIFI module when motion state changes according to the variation self adaptation of motion state.Specifically as described in step S200.
During concrete enforcement, described self adaptation adjusting module 30 comprises: computing unit, judging unit and self adaptation adjustment unit.Described computing unit is for calculating the motion state of mobile terminal according to motion state information.Described judging unit, for by motion state and the contrast of predetermined movement state, judges whether described motion state changes.Described self adaptation adjustment unit, for when motion state accelerates, is accelerated the scanning frequency of WIFI module; When motion state is slack-off, reduce the scanning frequency of WIFI module.
Further, described mobile terminal also comprises the GPS module, for obtaining the GPS information of mobile terminal, according to GPS information, judges that mobile terminal is indoor or outdoor; If outdoor stop scan period of WIFI module, if indoor start motion sensor, specifically as described in above-mentioned embodiment.
