It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of additional identical elements in the process, method, article, or apparatus that comprises the element.

At present, the standby power consumption of the wifi receiver in the target device is mainly caused by excessive current of receiving beacon (beacon) frame when waking up. And with the continuous update of the wifi standard, the beacon frame is longer and longer, which directly leads to the longer and longer time for the wifi receiver to receive the beacon frame and the larger and larger standby power consumption.

In order to solve the problem of the prior art, embodiments of the present invention provide a method and an apparatus for switching a working mode of a wifi receiver, an electronic device, and a computer storage medium. First, a method for switching the working modes of the wifi receiver provided in the embodiment of the present invention is described below.

Fig. 1 shows a schematic flowchart of a method for switching operating modes of a wifi receiver according to an embodiment of the present invention. As shown in fig. 1, the method for switching the operation mode of the wifi receiver may include the following steps:

s101, receiving beacon frames based on a preset period.

S102, analyzing the beacon frame, and judging whether TIM or DTIM in the analyzed beacon frame is effective or not.

S103, under the condition that the TIM or the DTIM is effective, whether the TIM or the DTIM meets preset conditions is judged.

And S104, under the condition that the TIM or the DTIM is determined to meet the preset condition, stopping receiving the beacon frame and executing the sleep operation on the wifi receiver.

In one embodiment, after determining whether the TIM or DTIM satisfies the predetermined condition, the method may further include:

under the condition that TIM or DTIM does not meet the preset conditions, continuously receiving beacon frames and carrying out frame check sequence FCS (FCS) check to obtain a check result;

In one embodiment, the determining whether the TIM or DTIM satisfies the predetermined condition includes:

In one embodiment, in the case that it is determined that TIM or DTIM satisfies a preset condition, stopping receiving beacon frames and performing a sleep operation on a wifi receiver includes:

and under the condition that the comparison result is that the SNR or the RSSI is greater than or equal to a preset demodulation threshold, stopping receiving the beacon frame and executing sleep operation on the wifi receiver.

Fig. 2 is a schematic diagram of positions of TIM or DTIM according to an embodiment of the present invention, where the position indicated by an arrow in fig. 2 is the position of TIM or DTIM in a complete beacon frame. If the wifi receiver calculates that the current RSSI and SNR is above the demodulation threshold, it can determine that the TIM or DTIM at this time is valid, and if the TIM or DTIM indicates that the Access Point (AP) has no buffered packets to send to the Station (STA), the STA can immediately go to sleep, wait for the next DTIM to wake up again, so that the receiving time will decrease to the original 1/3 to 1/2. If the TIM/DTIM indicates that the AP has a cache packet to send to the STA at the moment, the STA continues to receive the cache packet and performs the final Frame Check Sequence (FCS) Check, and if the FCS Check is correct, the wifi is awakened to enter an Awakening (ACTIVE) mode.

As shown in fig. 3, the wifi receiver performs the switching of the operation mode, and may switch from the sleep state to the awake state if the TIM or DTIM is valid, and accordingly may also switch from the awake state to the sleep state. Specifically, the receiver in the sleep state (state 1, completely turned off) receives the beacon frame based on a preset period, that is, the receiver receives the beacon frame (state 2, partially turned on), and then judges whether TIM or DTIM in the beacon frame meets the wakeup condition, if not, the receiver returns to the state 1, so that the duration of the state 2 is reduced, and the power consumption is reduced; if the wake-up condition is met, the receiver enters a wake-up state (state 3, fully on). Furthermore, from state 3, a sleep into state 1 is also possible.

The working mode switching method of the wifi receiver receives a beacon frame based on a preset period; analyzing the beacon frame, and judging whether a notification indication message TIM or a delivery notification indication message DTIM in the analyzed beacon frame is valid or not; under the condition that the TIM or the DTIM is determined to be effective, judging whether the TIM or the DTIM meets a preset condition; and under the condition that the TIM or the DTIM is determined to meet the preset condition, stopping receiving the beacon frame and performing sleep operation on the wifi receiver. Therefore, the method stops receiving the beacon frame and performs the sleep operation on the wifi receiver when the TIM or the DTIM is determined to meet the preset condition, and wifi standby power consumption can be greatly reduced because the TIM or the DTIM is in a very front part of the beacon frame. And whether the receiving is correct or not is judged by calculating whether the SNR or the RSSI is more than or equal to a demodulation threshold, so that the receiving of the beacon frame is ended in advance, and the standby power consumption is reduced. In addition, the practical scene and product to which the working mode switching method of the wifi receiver can be applied can include: the Internet of Things (IOT), intelligent home, intelligent doorbell, wireless handheld equipment and The like.
