Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
In this embodiment, a WiFi device is in communication connection with an external server via a WiFi route, and fig. 1 shows a flowchart of this embodiment. Referring to fig. 1, the power consumption control method of the present embodiment includes:
and S1, controlling the WiFi equipment to enter the sleep state and sending a frame signal for informing the WiFi equipment that the WiFi equipment enters the sleep state to the WiFi route.
In step S1, the frame signal for notifying the WiFi device that it has entered the Sleep state may include a PS-Sleep frame, and after receiving the PS-Sleep frame sent by the WiFi device, the WiFi route may buffer data sent by the external server for the WiFi device.
Further, when a TBTT (Target Beacon Transmission Time, Beacon scheduled Transmission Time) arrives, the WiFi route actively sends a Beacon frame, the WiFi device actively (enters an awake state in advance at the TBTT Time) receives the Beacon frame, and performs Time synchronization by using the Beacon frame.
S2, judging whether to control the flow sent by the external server to the WiFi route;
if yes, go to step S3; if not, go to step S4;
s3, switching the WiFi equipment to a first mode;
and S4, switching the WiFi device to the second mode.
In this embodiment, the operation mode of the WiFi device may be switched according to whether to control traffic sent to the WiFi route by an external server in communication connection with the WiFi device. Specifically, in this embodiment, the situation that the flow control needs to be performed may include that the speed of sending data by the external server is faster than the speed of receiving data by the WiFi device, and in this situation, in order to avoid data loss, the speed of sending data by the external server needs to be controlled.
For example, step S2 may specifically include a step of determining whether the remaining cache of the WiFi device is smaller than a first threshold, when the remaining cache of the WiFi device is smaller than the first threshold, determining to control the traffic sent by the external server to the WiFi route, and when the remaining cache of the WiFi device is not smaller than the first threshold, determining not to control the traffic sent by the external server to the WiFi route. The first threshold value can be set in a self-defined mode according to practical application.
For another example, step S2 may specifically determine, by combining the current WiFi signal strength, the current WiFi transmission rate, the size of the data to be downloaded, and the like, whether to control the traffic sent by the external server to the WiFi route.
Further, in this embodiment, when it is necessary to control the traffic sent by the external server to the WiFi route, a download stop request for requesting the external server to stop sending data to the WiFi route may be directly sent to the external server, so as to stop the external server from sending data to the WiFi route, or the size of the receive window of the WiFi device may be set to 0 according to a sliding window protocol in the TCP protocol, so that the external server no longer sends data to the WiFi route.
In this embodiment, when it is necessary to control a traffic sent from an external server to a WiFi route, the WiFi device is switched to a first mode, and in the first mode, the WiFi device sends a frame signal for receiving data to the WiFi route when the WiFi route notifies that the data is received, and enters a sleep state when the data reception is completed.
Specifically, in this embodiment, the first mode may be a PS-Poll mode, and fig. 2 shows a signaling diagram of the PS-Poll mode. Referring to fig. 2, in the PS-Poll mode, the WiFi device is in a sleep state, when the TBTT arrives and the beacon frame indicates that there is data, the WiFi device may send a PS-Poll frame for receiving the data, after the WiFi route receives the PS-Poll frame, the WiFi route may reply a data frame to the WiFi device, if the WiFi device further needs to acquire the data, the WiFi device needs to send the PS-Poll frame again, and when the WiFi device does not need to acquire the data, the WiFi device enters the sleep state.
In this embodiment, the first mode may also be a UAPSD (Unscheduled Automatic Power save delivery) mode, and fig. 3 shows a signal transceiving schematic diagram of the UAPSD mode. Referring to fig. 3, in the UAPSD mode, the WiFi device is in a sleep state, when the TBTT arrives and the beacon frame indicates that there is data, the WiFi device may send a Trigger frame for receiving the data, after receiving the Trigger frame, the WiFi router may reply a plurality of data frames to the WiFi device, if the WiFi device still needs to acquire the data, the Trigger frame needs to be sent again, and when the WiFi device does not need to acquire the data, the WiFi device enters the sleep state.
In this embodiment, when it is not necessary to control a traffic sent from an external server to a WiFi route, the WiFi device is switched to a second mode, in the second mode, the WiFi device enters an active state when the WiFi route notifies receiving data and sends a frame signal for notifying that the WiFi device has entered the active state to the WiFi route, and after the data reception is completed, the WiFi device enters a sleep state after waiting for a preset time and sends a frame signal for notifying that the WiFi device has entered the sleep state to the WiFi route. In the second mode, the WiFi route does not need to cache data for the WiFi device, and the WiFi device does not need to send a frame signal for receiving data to the WiFi route for multiple times according to the size of the cached data, so that a large amount of data throughput can be achieved.
Specifically, in this embodiment, the second mode may be a Fast PS mode, and fig. 4 shows a signal transceiving diagram of the Fast PS mode. Referring to fig. 4, in a Fast PS mode, a WiFi device is in a Sleep state, when a TBTT arrives and a beacon frame indicates data, the WiFi device may send a PS-Active frame for notifying that the WiFi device has entered an Active state, and has informed that it can continuously receive data, and after the WiFi device has no data reception, the WiFi device enters the Sleep state after waiting for a preset time (idle Timeout), and sends a PS-Sleep frame to a WiFi route.
Further, the power consumption control method of this embodiment may further include a step of determining whether the remaining cache of the WiFi device is greater than a second threshold, and with the release of the cache of the WiFi device, when the remaining cache of the WiFi device is greater than the second threshold, sending a download request to the external server for requesting the external server to send data to the WiFi route. In this embodiment, the second threshold may be set in a customized manner according to the actual application and is greater than the first threshold. In addition, on the basis that the size of the TCP receiving window of the WiFi device is set to 0 according to the TCP protocol to stop the external server from transmitting data to the WiFi route, when data needs to be downloaded from the server, the size of the TCP receiving window of the WiFi device may be recovered according to the TCP protocol to enable the external server to transmit data to the WiFi route.
In this embodiment, the WiFi device may be a WiFi headset or a WiFi speaker. For example, when listening to music on-line using a WiFi headset, a download request for downloading audio data may be sent to an external server and the first mode may be entered to quickly download the audio data. When the cache of the WiFi headset is full, a download stop request can be sent to the external server, the second mode is entered, the sleep state can be rapidly entered, and meanwhile a small amount of audio data can be acquired. And after the WiFi earphone buffer is released to a certain degree, the downloading request can be sent to the external server again, and the first mode is entered to continue downloading the audio data.
In addition, in this embodiment, a switching instruction may be directly sent to the WiFi device, the WiFi device is switched to the first mode or the second mode, or a switching instruction that controls the WiFi device to switch to the first mode or the second mode may be carried in the frame signal, and the WiFi device may obtain a specific switching instruction by analyzing the frame signal to be sent to the WiFi route.
The embodiment realizes that the WiFi equipment is switched between the first mode and the second mode based on whether the flow sent to the WiFi route by the external server in communication connection with the WiFi equipment is controlled, wherein the WiFi equipment can quickly enter a sleep state in the first mode, high throughput can be realized in the second mode, the power consumption of the WiFi equipment powered by a battery is optimized, the power saving mode of the WiFi equipment is further optimized, and the user experience is improved.

The device also can comprise a setting module, when the traffic sent to the WiFi route by the external server needs to be controlled, the setting module is used for setting the size of the receiving window of the WiFi device to 0 according to the sliding window protocol in the TCP protocol, so that the external server does not send data to the WiFi route any more.
In this embodiment, when it is necessary to control a traffic sent from an external server to a WiFi route, the WiFi device is switched to a first mode, and in the first mode, the WiFi device sends a frame signal for receiving data to the WiFi route when the WiFi route notifies that the data is received, and enters a sleep state when the data reception is completed.
