The embodiment of the present invention of embodiment one provides a kind of method of reduction WIFI access point power consumptions, as shown in Fig. 2 the described method comprises the following steps 101-104.
101st, WIFI access points perform the first power consumption mode within the current Beacon frame periods for having sent Beacon frames, and perform the first operation.First power consumption mode includes the normal mode of operation that the peripheral circuit of WIFI IC and WIFI IC in the WIFI access points are carried out.First operation includes：
102nd, the first timer of first power consumption mode is started；
103rd, judge access request whether is received in the timing of the first timer, and judge whether the WIFI access points enter next Beacon frame periods；
104th, it is determined that do not receive the access request, and in the case that the WIFI access points do not enter into next Beacon frame periods, the second power consumption mode is performed after first timer time-out；The power consumption of second power consumption mode is less than the power consumption of first power consumption mode.Wherein, second power consumption mode includes the low-power consumption mode that the WIFI IC and WIFI IC peripheral circuit is carried out.The low-power consumption mode includes：Dormancy, standby or shutdown, but not limited to this.When the WIFI access points are in the first power consumption mode, circuit is enclosed in the sunset fore-telling of the integrated circuit and integrated circuit of WIFI access points can carry out normal work, now, the WIFI access points are in normal operating conditions, when the WIFI access points are in the second power consumption mode, the integrated circuit of WIFI access points and the peripheral circuit of integrated circuit are likely to be at off-position, now, and the WIFI access points are in dormancy, standby or off-mode.The embodiment of the present invention provides a kind of method of reduction WIFI access point power consumptions, when performing the first power consumption mode, by the first timer for starting first power consumption mode, and it has been switched to the second power consumption mode after first timer time-out, the power consumption of second power consumption mode is less than the power consumption of first power consumption mode, relative in the prior art, the situation of the first power consumption mode is constantly in after Beacon frames are sent, the first power consumption mode is not only existed within a Beacon frame period in the present invention, it is also in the second power consumption mode, so that by the lower power consumption of WIFI IC and WIFI IC peripheral circuit in WIFI access points within the current Beacon frame periods.Embodiment two The embodiment of the present invention provides a kind of method of reduction WIFI access point power consumptions, as shown in Figure 3, the executive agent of methods described is WIFI access points, is illustrated by taking the Station connection requests that the WIFI access points receiving terminal is sent as an example, methods described includes：Following steps 201 204；
201st, WIFI access points determine not receiving the Station connection requests of terminal transmission in preset time, by performing step 201, it can determine that WIFI access points do not receive the Station connection requests of terminal transmission in preset time range, so as to after no Station connection requests are confirmed, implement the method that the present invention saves power consumption within the follow-up Beacon frame periods beyond preset time range.
Wherein, the preset time can be determined by the length in Beacon frame periods, specifically, because the length in each Beacon frame periods is identical, then the preset time can be at least one Beacon frame period.Example, if the WIFI access points do not receive the Station connection requests of terminal transmission within two Beacon frame periods, implement the method that the present invention saves power consumption within the follow-up Beacon frame periods after two Beacon frame periods.
202nd, WIFI access points perform the first power consumption mode within the current Beacon frame periods after Beacon frames have been sent.First power consumption mode includes the normal mode of operation that the peripheral circuit of WIFI IC and WIFI IC in the WIFI access points are carried out.In the embodiment of the present invention, since each Beacon frame periods be start to send current Beacon frames to the time interval that Beacon frames are sent next time.
203rd, the first timer of first power consumption mode is started.
204th, judge the Station access requests that terminal is sent whether are received in the timing of the first timer, in embodiments of the present invention, if terminal sends Station access requests in the timing of the first timer, step 209 is performed;If terminal does not send Station access requests, step 205 is performed.
205th, judge whether the WIFI access points enter next Beacon frame periods.During 205 steps are realized, WIFI access points judge whether it enters next Beacon frame periods, can specifically be completed by following two implementations：Implementation one
Step 1:Within the current Beacon frame periods, the N number of power consumption mode of the first predetermined number is set, described N power consumption mode of predetermined number includes first power consumption mode and the second power consumption mould Formula, and first power consumption mode number than second power consumption mode number more than 1;Step 2:Whether judge currently performed power consumption mode is n-th power consumption mode；If currently performed power consumption mode is n-th power consumption mode, the n-th power consumption mode enters next Beacon frame periods after terminating；If currently performed power consumption mode is not n-th power consumption mode, next Beacon frame periods are not entered into.Whether example, it is n-th power consumption mode that currently performed power consumption mode can be judged by setting counter.Assuming that initial hour counter size is 0, and when performing first power consumption mode or second power consumption mode, counter cumulative 1, and judge whether the size of nonce counter is less than or less than or equal to N.Because the WIFI access points were sent in the Beacon current Beacon frame periods, if not receiving the Station access requests of terminal transmission, execution first power consumption mode and second power consumption mode can be circulated, and first power consumption mode is first carried out, it therefore, it can judge whether currently performed power consumption mode is the N power consumption mode by setting the accumulated value of counter.Implementation two judges whether to enter next Beacon frame periods according to Beacon frame period timers.If Beacon frame period timer expiries, into next Beacon frame periods；If Beacon frame period timers are not timed-out, next Beacon frame periods are not entered into.Specifically, because the length in each Beacon frame periods is identical, then can set a timer to judge whether to enter next Beacon frame periods, the timer when an a length of Beacon frame period length；If Beacon frame period timer expiries, into next Beacon frame periods, if Beacon frame period timers are not timed-out, next Beacon frame periods are not entered into.
Optionally, timing of the second timer within the current Beacon frame periods and timing in next Beaco frame periods are identical or different；Timing of the first timer within the current Beacon frame periods and timing in next Beacon frame periods are identical or different.
If the 206, the terminal does not send the Station access requests, and the WIFI access points do not enter into next Beacon frame periods, the second power consumption mode is performed after first timer time-out, the power consumption of second power consumption mode is less than the power consumption of first power consumption mode.As shown in fig. 4 a, the first power consumption mode and

consumption mode is performed within first Beacon frame periodaiWith the time T of the second power consumption modeajCan be with identical, can also be different, the time T of the first power consumption mode is performed within first Beacon frame periodaiCan be with identical, can also be different, perform the time T of the second power consumption modeajCan be with identical, can also be different；The time respectively T of the first power consumption mode is performed within second Beacon frame periodbl(i is the odd number more than or equal to 1）, the time of the second power consumption mode is respectively Tbj(j is the even number more than or equal to 1）, the time T of the first power consumption mode is performed within second Beacon frame periodblWith the time T of the second power consumption modebjCan be with identical, can also be different, the time T of the first power consumption mode is performed within second Beacon frame periodblCan be with identical, can also be different, perform the time T of the second power consumption modebjCan be with identical, can also be different.As shown in Figure 4 b, the electric current when sending Beacon frames is 12, the electric current of the first power consumption mode is being performed for Ii, is 1 performing the electric current of the second power consumption mode3 , 13Less than ^.Wherein, the time that performs of each the first power consumption mode is the timing in each first timer；The time that performs of each the second power consumption mode is the timing in each second timer.Optionally, second power consumption mode includes the low-power consumption mode that the WIFI IC and WIFI IC peripheral circuit is carried out.It can be seen that, by the way that WIFI IC and WIFI IC peripheral circuit are arranged on into low-power consumption mode, it is to avoid the current drain of operation in the normal mode of operation.Optionally, the low-power consumption mode includes：Dormancy, standby or shutdown, are certainly not limited to described low-power consumption mode, all to belong to the low-power consumption mode less than first power consumption mode.Wherein, for the dormancy and it is described it is standby can image be described as：It is described standby in either shallow sleep state, the dormancy is in than the standby deeper deep sleep, time required for the holding state of the WIFI access points from second power consumption mode returns to first power consumption mode, than the WIFI access points from the dormancy shape of second power consumption mode Time required for state returns to first power consumption mode is shorter.Optionally, timing TA2 of the second timer within the continuous M Beacon frame period of second predetermined number is identical；Timing TA1 of the first timer within the continuous M Beacon frame period of second predetermined number is identical.Optionally, timing TB2 of the second timer since the M+1 Beacon frame period in the Beacon frame periods of continuous 3rd predetermined number is identical, and TB2 is not equal to TA2;Timing TB I of the first timer since the M+1 Beacon frame period in the Beacon frame periods of continuous 3rd predetermined number is identical, and TB I are not equal to TA1;As shown in Fig. 5, the timing of first timer and second timer within first Beacon frame period and continuous two cycles in second Beacon frame period, namely TA1 and TA2 is Tan, the timing of first timer that can be in the Beacon frame periods of continuous 3rd predetermined number since the 3rd Beacon frame period and second timer, namely TB I and TB2 are Tbm, and Tan is not equal to Tbm.3rd predetermined number can be any positive integer.Optionally, the first timer can include multiple timings, the second timer can also include multiple timings, within a Beacon frame period, each timing of first timer can be with identical, can also be different, each timing of second timer can be with identical, can also be different, the timing of first timer can be with identical with the timing of second timer, can also be different, the timing of first timer and the timing of second timer can be pre-set according to actual needs, it can also be generated according to random function, the present invention is to this without limiting.
