Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in restriction the present invention.
Fig. 1 is the principle of device block diagram according to reduction WIFI power consumption of the present invention, and as shown in Figure 1, the device of reduction WIFI power consumption of the present invention comprises, gravity sensor module 101, WIFI module 102 and host side 103, wherein,
WIFI module 102 is connected respectively to gravity sensor module 101 and host side 103 by hardware interface, and it receives the mobile message that gravity sensor module 101 sends, and scans.For WIFI module 102, gravity sensor module 101 has the term of validity by the mobile message that hardware interface transmits, if the time exceeds the term of validity, then removes this information; When WIFI module 102 went to scanning, the mobile message that inquiry gravity sensor module 101 is sent if having, represented that then intelligent movable equipment is in the movement, can directly carry out scanning; If not mobile, then can determine whether to carry out scanning according to self-defining rule, this rule can be " cancellation scanning ", also can be that 101 numbers of inquiry gravity sensor module are accumulated to and to a certain degree just do single pass.
Host side 103, it is connected respectively to gravity sensor module 101 and WIFI module 102 by hardware interface, is used for the scanning work of control WIFI module 102.
Fig. 2 is the method flow diagram according to reduction WIFI power consumption of the present invention, below with reference to Fig. 2, the method that reduces the WIFI power consumption of the present invention is described in detail.
At first, in step 201, judge whether the host side of mobile radio terminal is in Suspend Mode (park mode), if host side is in Suspend Mode, then forward step 202 to; If host side is in operational mode, then forward step 203 to; The host side of mobile radio terminal has two kinds of mode of operations usually: a kind of is that the host side of mobile radio terminal is in operational mode, and another kind is that the host side of mobile radio terminal is in Suspend Mode.
In step 202, WIFI module 102 is initiated scanning, and in this step, the host side of mobile radio terminal is in resting state, can not control the scanning of WIFI module 102, and scanning this moment is determined by WIFI module 102.At first need to differentiate the validity of the scanning of WIFI, the present invention judges that by gravity sensor module 101 current mobile radio terminal is in movement, still be in static state, if static state, quantity and the signal of AP around it also are metastable so, and the scanning frequency of WIFI can significantly reduce even stop this moment.
Purpose from scanning, WIFI scanning can be divided into two kinds, a kind of is that current WIFI does not connect, the purpose of scanning is in order to scan the AP of periphery as early as possible, and can connect up rapidly, this type of scanning frequency is higher usually, and another kind is that current WIFI connects, be same SSID in order to be connected to the better AP(of signal with the AP that has been connected) scanning done, the frequency of this type of scanning is lower usually.
In step 203, the host side 103 of mobile radio terminal is initiated scanning, the scanning work of control WIFI module 102.In this step, because the host side of mobile radio terminal does not have dormancy to be in running status, WIFI scanning is decided by host side, and WIFI module 102 is controlled by the host side of mobile radio terminal, if do not connect AP, the purpose of scanning is to be connected to AP; If be connected to AP, the purpose of scanning is in order to be connected to the AP of the better same SSID of signal.
At first host side need be differentiated the validity of the scanning of WIFI, the present invention judges that by gravity sensor module 101 current mobile radio terminal is in movement, still be in static state, if static state, quantity and the signal of AP around it also are metastable so, and the scanning frequency of WIFI can significantly reduce even stop this moment.
In step 204, WIFI module 102 is prepared to scan.
In step 205, WIFI module 102 reads the mobile message that gravity sensor module 101 sends.
In step 206, WIFI module 102 has judged whether mobile message, if mobile message (mobile radio terminal is in mobile status) is arranged, then carries out next step; Otherwise, forward step 208 to.
In step 207, WIFI module 102 is carried out scanning work.
In step 208, judge whether to scan according to rule, if then WIFI module 102 is carried out scanning work according to rule, otherwise WIFI module 102 stops scanning.Above-mentioned scanning rule can be " cancellation scanning ", also can be repeatedly to scan to be accumulated to a certain degree just to do single pass.By this method, reduced the power consumption of WIFI module.
The device and method of reduction WIFI power consumption of the present invention, adopt the information mutual communication between WIFI module and the gravity sensor module, make WIFI module 102 can in time obtain the position mobile status of current device, thereby determine whether really need carry out WIFI scanning.For then cancellation of unwanted WIFI scanning, thereby reduce the WIFI power consumption, increased the cruising time of intelligent movable equipment.
The host side of mobile radio terminal is in resting state, can not control the scanning of WIFI module 102, and scanning this moment is determined by WIFI module 102; If the host side of mobile radio terminal does not have dormancy, scanning is decided by host side, and WIFI module 102 is controlled by host side, and at this moment, host side determines that according to the mobile message of gravity sensor whether triggering the wifi chip does scanning.If can not do according to scanning rule, then can power saving.Therefore, no matter whether host side is hung up, this method can produce power saving effect.
One of ordinary skill in the art will appreciate that: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment the present invention is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme of aforementioned each embodiment record, perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
