Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a control method, device, electronic device and storage medium for a Wi-Fi device. Background Art

[0002] With the development of wireless communication technology, Wireless Fidelity (Wi-Fi) technology has been widely used. However, when Wi-Fi is applied to electrical devices, low power consumption is usually required.

[0003] In the related art, low power consumption is generally achieved by putting the Wi-Fi device into a sleep state, that is, when it is found that there is no data communication between the Wi-Fi device and the access point (AP), the Wi-Fi device is put into a sleep state, and then switched to an awake state when the AP sends a beacon frame, and whether it is necessary to communicate with the AP is determined based on the Beacon frame. Assuming that the AP sends Beacon frames at a period of 100ms, the Wi-Fi device needs to wake up once every 100ms, which is called DTIM1. If the Wi-Fi device needs to further reduce power consumption, it can also wake up once every 200ms, which is called DTIM2, or wake up once every 300ms, which is called DTIM3. However, the problem with DTIM2 and DTIM3 is that the communication needs of the AP may not be known in time, resulting in excessive delay. Excessive delay may cause the AP to think that the Wi-Fi device has been disconnected, resulting in the need for the Wi-Fi device to reconnect, which will undoubtedly consume more power.

[0004] Therefore, how to reasonably achieve low power consumption of Wi-Fi devices remains a technical problem that needs to be solved urgently. Summary of the invention

[0005] The embodiments of the present application provide a control method, an apparatus, an electronic device, and a storage medium for a Wi-Fi device, so as to reasonably realize low power consumption of the Wi-Fi device.

[0017] When the signal quality of the wireless signal is not higher than the preset signal quality, a second ratio value is determined as the Beacon frame ratio, and the second ratio value is smaller than the first ratio value.

[0018] In some embodiments, the signal quality of the wireless signal is determined by the misjudgment rate of the sleep condition when the MAC layer component does not correct the decoded data, or the signal quality of the wireless signal is determined by the signal-to-noise ratio of the wireless signal at the PHY layer.

[0019] In some embodiments, the first ratio value is 100%.

[0020] In a second aspect, an embodiment of the present application provides a control device for a Wi-Fi device, including:

[0022] The decoding module is used to call the physical PHY layer component to decode the currently received target Beacon frame;

[0023] A processing module, configured to perform low-power processing on the target Beacon frame, wherein the low-power processing means that when the amount of decoded data reaches a multiple of a preset amount, a media access control MAC layer component is called to determine whether the newly added preset amount of decoded data meets a sleep condition;

[0024] The second switching module is used to switch to the sleep state if it is determined that the sleep condition is met.

[0025] In some embodiments, it also includes:

[0026] A first determination module, configured to determine a proportion of Beacon frames to be processed with low power consumption based on a signal quality of a wireless signal carrying the target Beacon frame;

[0027] A second determination module is used to determine the numbering characteristics of Beacon frames for low power consumption processing based on the Beacon frame ratio;

[0028] The processing module is further configured to perform low power consumption processing on the target Beacon frame if it is determined that the number of the target Beacon meets the numbering characteristics.

[0029] In some embodiments, the first determining module is specifically configured to:

If it is determined that the sleep condition is met, it switches to a sleep state. In this way, when the Wi-Fi device is in a sleep state, the preset amount of decoded data obtained by decoding the target Beacon frame can be used to determine whether the sleep condition is met based on this part of the decoded data, without having to wait until all the decoded data is obtained before making a judgment. This can effectively shorten the wake-up time of the Wi-Fi device, allowing the Wi-Fi device to enter the sleep state faster, thereby reasonably achieving the purpose of low power consumption.

[0045] In order to reasonably achieve low power consumption of a Wi-Fi device, the embodiments of the present application provide a control method, an apparatus, an electronic device, and a storage medium for a Wi-Fi device.

[0046] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0047] In order to facilitate the understanding of this application, the technical terms involved in this application are:

[0048] Wi-Fi devices refer to devices that access the network through Wi-Fi, which usually require an external power supply or battery power. Common Wi-Fi devices include smartphones, tablets, portable personal computers, sweeping robots, Wi-Fi cameras, smart door locks, etc. The working states of Wi-Fi devices include sleep state and wake state. The sleep state refers to the state of the Wi-Fi device when it is not transmitting data, and the wake state refers to the state of the Wi-Fi device when it is transmitting data.

[0049] AP, the communication bridge between wireless network and wired network, is the core device of building wireless local area network (WLAN). Wi-Fi devices within the signal coverage of AP can communicate through AP. In wireless network, AP is equivalent to the hub of wired network, which can connect various Wi-Fi devices.

[0050] The physical (Physical, PHY) layer is the lowest layer in the Open System Interconnection Reference Model (OSI). It is directly oriented to the physical media (i.e., communication channels) that actually carry out data transmission. The transmission unit of the physical layer is bit, i.e., a binary bit ("0" or "1"). The actual bit transmission must rely on the transmission equipment and physical media, but the physical layer does not refer to a specific physical device, nor does it refer to the physical media for signal transmission. Instead, it refers to providing a physical connection for the upper layer (data link layer) to transmit the original bit stream above the physical media. The physical layer stipulates: to create, maintain, and dismantle the physical links required for data transmission, and to provide mechanical, electronic, functional, and standardized characteristics. Simply put, the physical layer ensures that the original data can be transmitted on various physical media. In an embodiment of the present application, the functions of the PHY layer can be implemented as PHY layer components, that is, the PHY layer components can implement all the functions of the PHY layer such as decoding and processing Beacon frames.

[0051] The Media Access Control (MAC) layer is mainly responsible for controlling the physical medium connected to the physical layer. Generally, after the decoded data of the PHY layer reaches the MAC layer, it is first verified. After the verification is completed, it is determined whether there is a communication demand and subsequent operations are performed. In the embodiment of the present application, the function of the MAC layer can be implemented as a MAC layer component.

[0052] Signal-to-noise ratio (SNR) refers to the ratio of signal to noise in an electronic device or electronic system. The unit of measurement for signal-to-noise ratio is dB, and its calculation method is 10lg (Ps / Pn), where Ps and Pn represent the effective power of signal and noise respectively, which can also be converted into a ratio of voltage amplitude: 20Lg (Vs / Vn), where Vs and Vn represent the "effective value" of signal and noise voltage respectively. The signal here refers to the electronic signal from outside the device that needs to be processed by this device, and the noise refers to the irregular additional signal (or information) that does not exist in the original signal after passing through the device, and this signal does not change with the change of the original signal.

[0053] Figure 1 An application scenario diagram of a control method for a Wi-Fi device provided in an embodiment of the present application includes an AP and a Wi-Fi device, wherein:

[0054] AP can transmit signals to the outside. All Wi-Fi devices within its signal coverage range can request to access the AP and then access the network through the AP.

[0055] Wi-Fi devices can transmit data with APs in the awake state. When there is no data transmission, they can enter the sleep state and wake up at a certain period to receive Beacon frames sent by APs. The Beacon frame contains an identifier of whether the AP has a data cache belonging to the Wi-Fi device. If the Wi-Fi device finds that the Beacon frame contains an identifier of its own data cache, it can remain awake and transmit data to the AP; if it finds that the Beacon does not contain an identifier of its own data cache, it can enter the sleep state until the next Beacon frame reception cycle arrives and repeats the above operations.

[0056] Normally, in order to reduce the power consumption of Wi-Fi devices, when the Wi-Fi device is in sleep state, if it is determined that the Beacon frame reception period indicated by the AP has been reached, it will switch to the awake state, call the PHY layer component to decode the currently received target Beacon frame, and after obtaining all the decoded data of the target Beacon frame, call the MAC layer component to correct all the decoded data. After the correction is completed, it will determine whether the sleep conditions are met based on all the decoded data. If so, it will switch to the sleep state.

[0057] In order to further reduce the power consumption of Wi-Fi devices, the embodiment of the present application proposes a solution for decoding the target Beacon frame while judging whether the decoded data meets the sleep condition. Since it is not necessary to obtain all the decoded data to judge whether the sleep condition is met, and the sleep state can be entered when the sleep condition is met, the wake-up time of the Wi-Fi device can be effectively shortened, allowing the Wi-Fi to enter the sleep state faster.

[0058] The solution of the embodiment of the present application is introduced below with reference to a specific flow chart.

[0059] Figure 2 A flowchart of a control method for a Wi-Fi device provided in an embodiment of the present application, the method is applied to Figure 1 In a Wi-Fi device, the method includes the following steps.

[0060] In step 201, when the Wi-Fi device is in a sleep state, if it is determined that the Beacon frame receiving period indicated by the AP has arrived, it switches to an awake state.

[0061] Among them, the Beacon frame receiving period is 100ms, 200ms, 300ms, etc.

[0062] In step 202, the PHY layer component is called to decode the currently received target Beacon frame.

[0063] The decoding process includes operations such as channel estimation, equalization, demapping, and decoding.

[0064] In actual applications, the target Beacon frame can be decoded while being received to improve processing efficiency.

[0065] In step 203, low power consumption processing is performed on the target Beacon frame, wherein low power consumption processing means that when the amount of decoded data reaches a multiple of a preset amount, a MAC layer component is called to determine whether the newly added preset amount of decoded data meets the sleep condition.

[0066] If the preset amount is 3 bytes, then when the amount of decoded data reaches 3 bytes, the MAC layer component can be called to determine whether the 3 bytes of decoded data meet the sleep conditions. When the amount of PHY layer decoded data reaches 6 bytes, the MAC layer component can be called again to determine whether the newly added 3 bytes of decoded data meet the sleep conditions, and so on.

[0067] The sleep condition is as follows: the decoded data contains a Traffic Indication Message Element ID (TIM EI), and the content of the TIM EI is not updated.

[0068] Generally, each Beacon frame contains Traffic Indication Message (TIM) information, but the TIM information may or may not contain TIM EI. By diagnosing the value of EI by the MAC layer component, it can be determined whether the TIM EI is received. If the TIM EI is received, it can be further determined whether the content of the TIM EI is updated to determine whether the above-mentioned sleep conditions are met.

[0069] Specifically, if the value of the MAC layer component diagnosis EI is 5, it is determined that the TIM EI is received. Further, the content of the TIM EI can be analyzed. If the content of the TIM EI is updated, it is determined that the sleep condition is not met. If the content of the TIM EI is not updated, it is determined that the sleep condition is met; if the value of the MAC layer diagnosis EI is not 5, it is determined that the TIM EI is not received.

[0070] In step 204, if it is determined that the sleep condition is met, the state is switched to the sleep state.

[0071] The above process is introduced below with an example.

[0072] Figure 3 A schematic diagram of the processing process of a target Beacon frame provided in an embodiment of the present application. Assume that the target Beacon frame is fully decoded by the PHY layer component to obtain a total of 9 bytes of decoded data, and the 9 bytes of decoded data are represented by: data block 1, data block 2, data block 3, and the size of each data block can be 3 bytes. Assume that the decoding rate of the PHY layer component is 2ms / data block, and the rate at which the MAC layer component determines whether the sleep condition is met is 1ms / data block. And assume that the MAC layer component determines that the sleep condition is met based on data block 2.

[0073] Then, under normal circumstances, it takes 6ms for the PHY layer component to complete all decoding processing. After the PHY layer component is fully decoded, the MAC layer component first performs correction. Assuming that the correction takes 1ms, after the correction is passed, the MAC layer component is called to determine whether the three data blocks meet the sleep condition. It takes 1ms to determine whether data block 1 meets the sleep condition, and 1ms for data block 2. When it is determined that data block 2 is completed, it is determined that the sleep condition is met and the sleep state is switched. Therefore, the whole process takes 9ms.

[0074] According to the scheme of the embodiment of the present application, if the preset amount is 3 bytes, the MAC layer component can be called every time a data block is obtained to determine whether the data block meets the sleep condition. In this way, data block 1 is obtained at the end of the 2nd ms, and the MAC layer component determines that data block 1 does not meet the sleep condition at the end of the 3rd ms. Data block 2 is obtained at the end of the 4th ms, and at the end of the 5th ms, the MAC layer component can determine that data block 2 meets the sleep condition and can switch to the sleep state. The whole process takes 5ms.

[0075] Obviously, the wake-up time of the Wi-Fi device is reduced from 9ms to 5ms, which enables the Wi-Fi device to enter the sleep state 4ms earlier, effectively shortening the wake-up time and thus reducing power consumption.

[0076] Generally, after obtaining the decoded data, the MAC layer component first corrects the decoded data, and then determines whether the decoded data meets the sleep condition after the correction. In the above embodiment, the MAC layer component directly determines whether the decoded data meets the sleep condition without correcting the decoded data, which may lead to errors in judgment, and the error probability is closely related to the signal quality of the wireless signal carrying the Beacon frame. To this end, low power consumption processing can be performed in combination with the signal quality of the wireless signal carrying the Beacon frame.

[0077] Figure 4 A flowchart of another method for controlling a Wi-Fi device provided in an embodiment of the present application includes the following steps.

[0078] In step 401, based on the signal quality of the wireless signal carrying the target Beacon frame, the proportion of Beacon frames to be processed with low power consumption is determined.

[0079] In some embodiments, the signal quality of the wireless signal carrying the target Beacon frame is determined by the false positive rate of the sleep condition when the MAC layer component does not correct the decoded data.

[0080] For example, a time period before the current time is selected. For each Beacon frame in this time period, after obtaining all the decoded data of the Beacon frame, the MAC layer component first corrects all the decoded data. After the correction, it determines whether the sleep condition is met based on all the decoded data. The obtained determination result is taken as determination result 1, and the determination result directly determined without correction is taken as determination result 2. If determination result 2 is different from determination result 1, a misjudgment can be recorded. Afterwards, the ratio of the number of misjudgments to the number of Beacon frames received in this time period is determined as the misjudgment rate of the sleep condition.

[0081] Furthermore, if the error rate of the sleep condition is higher than the set value, the signal quality of the wireless signal carrying the target Beacon frame is determined to be no higher than the preset signal quality. If the error rate of the sleep condition is not higher than the set value, the signal quality of the wireless signal carrying the target Beacon frame is determined to be higher than the preset signal quality.

[0082] In some embodiments, the signal quality of the wireless signal is determined by a signal-to-noise ratio of the wireless signal carrying the target Beacon frame at the PHY layer.

[0083] For example, 10 Beacon frames whose reception time is earlier than the target Beacon frame are selected, the signal-to-noise ratio of the wireless signal carrying each Beacon frame at the PHY layer is calculated, and the average value of the 10 signal-to-noise ratios is determined as the signal-to-noise ratio of the wireless signal carrying the target Beacon frame at the PHY layer.

[0084] Further, when the signal-to-noise ratio of the wireless signal carrying the target Beacon frame at the PHY layer is higher than a preset value, it is determined that the signal quality of the wireless signal carrying the target Beacon frame is not higher than the preset signal quality; when the signal-to-noise ratio of the wireless signal carrying the target Beacon frame at the PHY layer is not higher than the preset value, it is determined that the signal quality of the wireless signal carrying the target Beacon frame is higher than the preset signal quality.

[0085] In specific implementation, when the signal quality of the wireless signal is higher than the preset signal quality, the first ratio value can be determined as the Beacon frame ratio, and when the signal quality of the wireless signal is not higher than the preset signal quality, the second ratio value can be determined as the Beacon frame ratio, wherein the second ratio value is smaller than the first ratio value.

[0086] For example, the first ratio value is 50% and the second ratio value is 30%. That is to say, when the signal quality is higher than the preset signal quality, 50% of the Beacon frames can be processed with low power consumption. When the signal quality is not higher than the preset signal quality, 30% of the Beacon frames can be processed with low power consumption.

[0087] It is worth noting that when the first ratio value is 100%, that is, when the signal quality is higher than the preset signal quality, low power consumption processing is performed on all Beacon frames to achieve low power consumption to the greatest extent.

[0088] In step 402, based on the Beacon frame ratio, the numbering characteristics of the Beacon frames for low power consumption processing are determined.

[0089] Assuming that the Beacon frame ratio is 50%, the numbering characteristics of the Beacon frames for low power consumption processing may be an even number or an odd number; assuming that the Beacon frame ratio is 30%, the numbering characteristics of the Beacon frames for low power consumption processing may be a number modulo 3 equal to zero.

[0090] In step 403, when the Wi-Fi device is in the sleep state, if it is determined that the Beacon frame receiving period indicated by the AP has arrived, it switches to the awake state.

[0091] In step 404, the PHY layer component is called to decode the currently received target Beacon frame.

[0092] In step 405, if it is determined that the number of the target Beacon meets the numbering characteristics, the target Beacon frame is subjected to low power consumption processing, wherein low power consumption processing means that when the amount of decoded data reaches a multiple of a preset amount, the MAC layer component is called to determine whether the newly added preset amount of decoded data meets the sleep condition.

[0093] Assuming that the numbering feature is an even number, when the number of the target Beacon is an even number such as 2, 4, 6, ..., the target Beacon frame can be processed with low power consumption.

[0094] The implementation of the low power consumption processing in this step can be referred to step 203 and will not be described in detail here.

[0095] In step 406, if it is determined that the sleep condition is met, the state is switched to the sleep state.

[0096] In addition, if it is determined that the sleep condition is not met, the awake state can be maintained and data transmission with the AP can be started. When there is no data transmission with the AP within a preset time, the sleep state can be re-entered.

[0097] The above process is introduced below with an example.

[0098] For example, 10 Beacon frames are selected, the signal-to-noise ratio of the wireless signal carrying each Beacon frame at the PHY layer is calculated, and the average value of the 10 signal-to-noise ratios is calculated. If the average value is higher than the preset value, it is determined that the quality of the wireless signal is not high. If the average value is not higher than the preset value, it is determined that the quality of the wireless signal is high.

[0099] Assuming that the proportion of Beacon frames that are processed with low power consumption is 100% when the quality of the wireless signal is high, each Beacon frame received can be processed with low power consumption to maximize the low power consumption of the Wi-Fi device.

[0100] Assuming that the proportion of Beacon frames that are processed with low power consumption when the quality of wireless signals is not high is 20%, then one Beacon frame out of every five received Beacon frames can be processed with low power consumption. In this way, when the signal quality is not high, the power consumption of Wi-Fi devices can be reduced and the Wi-Fi devices can be informed of the AP data transmission requirements in a timely manner.

[0101] Based on the same technical concept, an embodiment of the present application also provides a control device for a Wi-Fi device. The principle of solving the problem by the control device for the Wi-Fi device is similar to that of the control method for the Wi-Fi device mentioned above. Therefore, the implementation of the control device for the Wi-Fi device can refer to the implementation of the control method for the Wi-Fi device, and the repeated parts will not be repeated.

[0102] Figure 5 A schematic structural diagram of a control device for a Wi-Fi device provided in an embodiment of the present application includes a first switching module 501 , a decoding module 502 , a processing module 503 , and a second switching module 504 .

[0103] The first switching module 501 is used for, when the Wi-Fi device is in a sleep state, switching to a wake-up state if it is determined that the beacon frame receiving period indicated by the access point AP has been reached;

[0104] The decoding module 502 is used to call the physical PHY layer component to decode the currently received target Beacon frame;

[0105] The processing module 503 is used to perform low-power processing on the target Beacon frame, wherein the low-power processing means that when the amount of decoded data reaches a multiple of a preset amount, a media access control MAC layer component is called to determine whether the newly added preset amount of decoded data meets the sleep condition;

[0106] The second switching module 504 is configured to switch to the sleep state if it is determined that the sleep condition is met.

[0107] In some embodiments, it also includes:

[0108] A first determination module 505 is used to determine the proportion of Beacon frames to be processed with low power consumption based on the signal quality of the wireless signal carrying the target Beacon frame;

[0109] A second determination module 506 is used to determine the numbering characteristics of Beacon frames for low power consumption processing based on the Beacon frame ratio;

[0110] The processing module 503 is further configured to perform low power consumption processing on the target Beacon frame if it is determined that the number of the target Beacon meets the numbering characteristics.

[0111] In some embodiments, the first determining module 505 is specifically configured to:

[0112] When the signal quality of the wireless signal is higher than the preset signal quality, determining the first ratio value as the Beacon frame ratio;

[0113] When the signal quality of the wireless signal is not higher than the preset signal quality, a second ratio value is determined as the Beacon frame ratio, and the second ratio value is smaller than the first ratio value.

[0114] In some embodiments, the signal quality of the wireless signal is determined by the misjudgment rate of the sleep condition when the MAC layer component does not correct the decoded data, or the signal quality of the wireless signal is determined by the signal-to-noise ratio of the wireless signal at the PHY layer.

[0115] In some embodiments, the first ratio value is 100%.
