[0036] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0037] The embodiment of the present application provides a method for receiving a beacon frame. The method can be applied to Figure 1 In the implementation environment shown. Figure 1 In the embodiment, at least one terminal 11 and an AP device 2 are included. The terminal 11 can be communicatively connected with the AP device 12 to receive a beacon frame sent by the AP device 12.

[0038] For example, the terminal 11 includes, but is not limited to, any electronic product capable of human-computer interaction with a user through one or more methods such as a keyboard, touchpad, touch screen, remote control, voice interaction, or handwriting device, such as a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a Pocket PC (PPC), a tablet computer, a smart car computer, a smart TV, a smart speaker, etc. Optionally, the AP device 12 may be a router.

[0039] Those skilled in the art should understand that the above-mentioned terminal 11 and AP device 12 are only examples. Other existing or future terminals or AP devices that are applicable to this application should also be included in the scope of protection of this application and are included here by reference.

[0040] Based on the above Figure 1 In the implementation environment shown, in the related art, the beacon frame sent by the AP device to the terminal carries a beacon period, which is used to indicate the difference between the sending time of the next beacon frame and the sending time of the current beacon frame carrying the beacon period. In other words, the beacon period indicates how long it will take for the AP device to send the next beacon frame after sending the current beacon frame carrying the beacon period. Therefore, the terminal can receive the beacon frame according to the beacon period. Among them, after opening the RF (Radio Frequency) window and receiving a beacon frame, the terminal can close the RF window and then obtain the beacon period carried by the beacon frame. Then, when the beacon period has passed since the last time the RF window was opened, the terminal opens the RF window again and receives the next beacon frame, thereby realizing the reception of the beacon frame.

[0041] Under normal circumstances, the actual interval of the AP device sending beacon frames is consistent with the interval indicated by the beacon period, so the terminal can normally receive beacon frames according to the beacon period. Figure 2 As shown in the figure, the actual interval of the AP device sending beacon frames and the interval indicated by the beacon period are both 102ms (unit: milliseconds). The terminal opens the RF window every 102ms according to the interval indicated by the beacon period, and closes it after a period of time. The beacon frame can be received normally during the period when the RF window is open.

[0042] However, in abnormal situations, the actual interval at which the AP sends beacon frames is inconsistent with the interval indicated by the beacon period, and the terminal cannot receive beacon frames normally according to the beacon period. Figure 3As shown in the figure, the actual interval for the AP to send beacon frames is 96ms, but the interval indicated by the beacon period is 102ms. The terminal then opens the RF window every 102ms according to the interval indicated by the beacon period and closes it after a period of time. However, the terminal cannot receive beacon frames during the open RF window. To enable the terminal to receive beacon frames, the RF window must be opened for a longer period of time. However, since opening the RF window requires power consumption, extending the opening period of the terminal increases the power consumption required by the terminal and shortens the terminal's battery life.

[0043] For example, this abnormality may be caused by an inaccurate beacon period on the AP device. Specifically, the AP device transmits beacon frames at an actual interval, but the beacon period indicates a different interval than the actual interval. Alternatively, this abnormality may be caused by a shift in the actual interval between beacon frame transmissions after the AP device has been in use for a long time, or by aging components of the AP device, which may cause the actual interval between beacon frame transmissions to shift.

[0044] Therefore, see Figure 4 , the embodiment of the present application provides a method for receiving a beacon frame, which can be applied to Figure 1 In the terminal shown. Figure 4 As shown, the method includes the following steps 401 to 403.

[0045] Step 401: Acquire multiple first beacon periods according to the reception times of multiple received beacon frames, where any first beacon period among the multiple first beacon periods is the difference between the reception times of two adjacent received beacon frames.

[0046] Among them, the terminal can receive multiple beacon frames within the historical period, and the historical period is also the period that has passed. The terminal can record the time when each beacon frame is received, thereby obtaining the reception time of multiple received beacon frames. It should be understood that the multiple received beacon frames are ordered, so the terminal can subtract the reception time of each two adjacent received beacon frames in the ordered multiple received beacon frames, thereby obtaining multiple first beacon periods. The multiple first beacon periods are beacon periods within the historical period, and the multiple first beacon periods are also ordered. For example, if there are 11 received beacon frames in total, the terminal can obtain 10 first beacon periods.

[0047] In some embodiments, the terminal may use all first beacon periods in the historical period as the multiple first beacon periods. In other embodiments, the terminal may select some first beacon periods from all first beacon periods as the multiple first beacon periods using a sliding window method to avoid an excessive number of selected multiple first beacon periods, which would affect the efficiency of subsequent predictions based on the multiple first beacon periods.

[0048] Exemplarily, if the sliding window corresponds to a reference number of first beacon periods, selecting a portion of the first beacon periods from all first beacon periods using the sliding window method may include selecting the reference number of first beacon periods adjacent to the current moment from all ordered first beacon periods. Furthermore, as the current moment continues to change, the number of received beacon frames continues to increase, the total number of first beacon periods also continues to increase, and the selected first beacon period also changes accordingly. This method ensures that the selected first beacon period is calculated using the reception time of the most recently received beacon frame. Consequently, the selected multiple first beacon periods are also relatively recent and timely, and subsequent predictions using such multiple first beacon periods have a higher accuracy rate.

[0049] For example, the reference number is 10, the total number of first beacon periods is 20, and the 20 first beacon periods are obtained based on the reception times of the 21 received beacon frames. Before the 22nd beacon frame is received, the 10 first beacon periods selected from the 20 first beacon periods are the 11th first beacon period to the 20th first beacon period. After the 22nd beacon frame is received, the total number of first beacon periods is updated to 21, and the 10 first beacon periods selected from the 21 first beacon periods are correspondingly updated to the 12th first beacon period to the 21st first beacon period. And so on, examples are not repeated.

[0050] Of course, the above implementations are examples and are not intended to limit the manner in which the terminal obtains multiple first beacon periods. Regardless of the manner in which the terminal obtains multiple first beacon periods, step 402 may be entered after obtaining multiple first beacon periods.

[0051] Step 402: predict a second beacon period within a reference period based on a plurality of first beacon periods, where the reference period is a period after a reception time of a last received beacon frame.

[0052] After obtaining multiple first beacon periods in the historical period, the terminal can predict the second beacon period in the reference period based on the multiple first beacon periods. The reference period is the period after the reception time of the last received beacon frame, or in other words, the reference period is a future period. It can be seen that the embodiment of the present application comprehensively considers multiple first beacon periods in the historical period to accurately predict the second beacon period in the future period, or to predict which second beacon period to use subsequently.

[0053] In an exemplary embodiment, predicting the second beacon period within a reference time period based on multiple first beacon periods includes: obtaining the weight corresponding to each first beacon period in the multiple first beacon periods; performing weighted average calculation on each first beacon period according to the weight corresponding to each first beacon period, and predicting the second beacon period within the reference time period.

[0054] The embodiments of the present application do not restrict the weights associated with each first beacon period; the weights associated with each first beacon period can be set based on experience or actual needs. In some embodiments, the weights associated with each first beacon period are the same. In this embodiment, a weighted average is calculated for each first beacon period according to the weights associated with each first beacon period, which is equivalent to calculating the average value of each first beacon period. The predicted second beacon period within the reference time period is then the average value of each first beacon period. Alternatively, in other embodiments, the weights associated with at least two of the multiple first beacon periods are different. For example, the weight associated with one of the multiple first beacon periods is different from the weights associated with the other first beacon periods. In another example, the weights associated with any two of the multiple first beacon periods are different. In this embodiment, different weights can be assigned to each first beacon period based on their different reference values, for example, assigning a higher weight to a first beacon period with a higher reference value.

[0055] Exemplarily, the difference between the reception times of two adjacent received beacon frames of any first beacon period and the target time is negatively correlated with the weight corresponding to any first beacon period. That is, for a first beacon period, the newer the two received beacon frames used to calculate the first beacon period, or in other words, the first beacon period is the most recent of multiple first beacon periods, the higher the reference value of the first beacon period, and thus the first beacon period is assigned a larger weight.

[0056] For example, in an embodiment of the present application, the first weight may be used as the weight corresponding to the latest first beacon period in multiple first beacon periods. Furthermore, the average value of the first beacon periods other than the latest first beacon period in the multiple first beacon periods is calculated, and the second weight is used as the weight corresponding to the average value, and the first weight is greater than the second weight. Taking a total of 10 ordered first beacon periods as an example, the second weight corresponding to the average value of the first 9 first beacon periods can be 0.3, and the first weight corresponding to the 10th latest first beacon period can be 0.7.

[0057] Of course, the embodiment of the present application can also make the difference between the reception time and the target time used to obtain two adjacent received beacon frames of any first beacon period positively correlated with the weight corresponding to any first beacon period, which is not limited in the embodiment of the present application.

[0058] Step 403: Receive a new beacon frame at a target time within the reference period, where the difference between the target time and the receiving time of the last received beacon frame is the second beacon period.

[0059] Since the second beacon period within the reference time period is predicted in step 402, the second beacon period can be used within the reference time period, so that the moment for receiving the new beacon frame is the target moment within the reference time period, and the difference between the target moment and the reception moment of the last received beacon frame is the second beacon period.

[0060] It should be noted that the process of the terminal receiving the beacon frame includes: opening the RF window and starting to receive the beacon frame, completing the reception of the beacon frame and closing the RF window in a period of time (for example, 7ms, which is related to the byte length occupied by the beacon frame to be received). In other words, the reception of the beacon frame is not completed instantaneously at one moment, but requires a period of time to complete. Based on this, the embodiment of the present application is based on the moment when the beacon frame starts to be received for statistics. The difference between the target moment and the reception moment of the last received beacon frame is the second beacon period, which means: based on the reception moment when the last beacon frame starts to be received, the target moment is reached after the second beacon period, the RF window is opened again at the target moment, and a new beacon frame is started to be received.

[0061] In other words, there are multiple moments in sequence on the time axis: start receiving the previous beacon frame, end receiving the previous beacon frame, start receiving a new beacon frame, and end receiving a new beacon frame. The difference between the moment of starting to receive the new beacon frame and the moment of starting to receive the previous beacon frame is the second beacon period. The difference between the moment of starting to receive the new beacon frame and the moment of ending to receive the previous beacon frame is the time when the terminal closes the RF window, or the sleep time of the terminal. In addition, the difference between the moment of ending to receive the previous beacon frame and the moment of starting to receive the previous beacon frame is the above-mentioned period of time, or the wake-up time of the terminal. Similarly, the difference between the moment of ending to receive the new beacon frame and the moment of starting to receive the new beacon frame is also the above-mentioned period of time, which also belongs to the wake-up time of the terminal. The terminal will go into sleep once after waking up and receiving a beacon frame. This method is also called DTIM (Delivery Traffic Indication Message) 1 method.

[0062] In some implementations, the embodiment of the present application may perform step 403 in any case. Alternatively, in other implementations, the embodiment of the present application performs step 403 only when certain conditions are met, and the certain conditions that need to be met include but are not limited to the following two.

[0063] The first condition: The terminal is in low-power mode. Receiving a new beacon frame at a target time within a reference period includes: when in low-power mode, executing the process of receiving a new beacon frame at a target time within the reference period. Since the new beacon frame is received at a target time within the reference period, the terminal can accurately open and close the RF window and accurately receive new beacon frames while the RF window is open. As a result, the terminal does not need to extend the RF window opening time to receive new beacon frames, thereby not increasing the terminal's power consumption. This is applicable to situations where the terminal is in low-power mode.

[0064] Exemplarily, if the first condition is not met, that is, the terminal is not in low power mode, then the terminal may not execute the reception of a new beacon frame at the target time within the reference time period. The reason is that when the terminal is not in low power mode, the RF window of the terminal is always open, and it is not necessary to close the RF window after opening it as in low power mode. Therefore, there will be no increase in power consumption due to extending the opening time of the RF window. Therefore, when the terminal is not in low power mode, the embodiment of the present application can enable the terminal to periodically execute step 401, that is, the terminal periodically obtains multiple first beacon periods, so that the terminal can enter step 402 after entering low power mode, and continue to execute step 403 accordingly.

[0065] The second condition is that the last received beacon frame carries the third beacon period, and the difference between the second beacon period and the third beacon period is greater than the reference threshold. Then, a new beacon frame is received at the target time within the reference time period, including: when the difference between the second beacon period and the third beacon period is greater than the reference threshold, the new beacon frame is received at the target time within the reference time period. The last received beacon frame may include an information element, which is used to carry the third beacon period. If the difference between the predicted second beacon period and the third beacon period is greater than the reference threshold, it means that the accuracy of the third beacon period is poor, and thus the terminal cannot receive a new beacon frame according to the third beacon period, but needs to execute step 403 to receive a new beacon frame according to the predicted second beacon period.

[0066] Exemplarily, if the second condition is not met, that is, the difference between the second beacon period and the third beacon period is less than or equal to the reference threshold, then the terminal may not receive a new beacon frame at the target time within the reference period, but instead receive a new beacon frame according to the third beacon period carried by the last received beacon frame. For example, the terminal receives a new beacon frame at the reference time, and the difference between the reference time and the reception time of the last received beacon frame is equal to the third beacon period. The reason is that in this case, the accuracy of the third beacon period is better. Since the terminal will continue to open the RF window for a period of time, even if there are some slight deviations in the third beacon period, it can ensure that the terminal accurately receives the new beacon frame during the opening of the RF window.

[0067] Next, the method for receiving beacon frames provided in the embodiment of the present application is further explained in combination with two application scenarios.

[0068] Application scenario 1: The beacon period of the AP device is inaccurate. In other words, the AP device sends beacon frames at an actual interval, but the beacon period indicates an interval that is different from the actual interval. Figure 5 As shown, the actual interval is, for example, 108 ms, and the interval indicated by the beacon period is, for example, 102 ms.

[0069] In application scenario 1, although the interval indicated by the beacon period differs from the actual interval at which the AP transmits beacon frames, the terminal receives multiple first beacon periods (i.e., multiple actual intervals). Therefore, the terminal accurately predicts the second beacon period to be 108ms based on these multiple first beacon periods. Therefore, the terminal does not receive new beacon frames at the 102ms interval indicated by the beacon period, but instead receives new beacon frames at the predicted 108ms second beacon period, thus ensuring accurate beacon frame reception.

[0070] Application scenario 2: After the AP device has been used for a long time, the actual interval of sending beacon frames has shifted, and the actual interval of sending beacon frames has shifted due to the aging of the components of the AP device. For example, see Figure 6 , the actual interval is 96ms, and the interval indicated by the beacon period is 102ms.

[0071] In the second application scenario, although the actual interval between beacon frames sent by the AP gradually changes from 102ms to 96ms due to factors such as aging of the AP's components, the terminal receives multiple first beacon periods, i.e., multiple actual intervals. Therefore, the terminal can accurately predict the second beacon period to be 96ms based on these multiple first beacon periods. Therefore, the terminal no longer receives new beacon frames according to the 102ms indicated by the beacon period, but instead receives new beacon frames according to the predicted 96ms second beacon period, thus ensuring accurate beacon frame reception.

[0072] In addition, actual tests were conducted on the methods for receiving beacon frames provided by the related technologies and the embodiments of the present application. During the actual tests, the DTIM1 method was adopted for both the related technologies and the embodiments of the present application, thereby obtaining the test data shown in Tables 1 and 2 below.

[0073] Among them, first, the opening time of the RF window is fixed to 7ms, and the test time is set to 60s (unit: seconds), so as to obtain the test data shown in Table 1. It can be seen from Table 1 that in this case, the related technology only received 212 beacon frames in the test time of 60s. Then, there is a large delay in the downlink communication direction (i.e., from the AP device to the terminal) in the related technology, and the downlink communication quality is poor. The AP device may interrupt the communication connection with the terminal. However, the embodiment of the present application can receive 574 beacon frames within the test time of 60s, which improves the success rate of receiving beacon frames. Then, the delay in the downlink communication direction is small, and the communication connection between the AP device and the terminal can be stably established. Therefore, it can be explained that the method provided by the embodiment of the present application can receive beacon frames more accurately, improve the success rate of receiving beacon frames, and ensure normal communication between the AP device and the terminal.

[0074] Table 1

[0075]

[0076]

[0077] In addition, the opening duration of the RF window is set dynamically, that is, if no beacon frame is received during the opening period of the RF window, the opening time of the RF window can be flexibly extended, thereby obtaining the test data shown in Table 2. As can be seen from Table 2, when the opening duration of the RF window can be dynamically set, the number of beacon frames received by the embodiment of the present application is slightly more than the number of beacon frames received in the related art. However, the average power consumption in the related art is very high, which is 3.53mA (unit: milliampere), indicating that the opening duration of the RF window is extended many times in the related art. The average power consumption of the embodiment of the present application is lower, which is 2.65mA, indicating that the embodiment of the present application can receive the beacon frame more accurately. Even if the opening time of the RF window needs to be extended, the number of times it needs to be extended is less than the number of times it needs to be extended in the related art. It also shows that the solution provided by the embodiment of the present application will not increase power consumption, thereby ensuring that the embodiment of the present application improves the success rate of receiving beacon frames when the required power consumption is low.

[0080] In summary, the embodiment of the present application obtains multiple first beacon periods based on the reception time of the received beacon frame, and then predicts the second beacon period within the reference time period after the reception time of the last received beacon frame based on the multiple first beacon periods, so that a new beacon frame can be received according to the predicted second beacon period within the reference time period, that is, the difference between the target time for receiving the new beacon frame and the reception time of the last received beacon frame is the second beacon period. Since the second beacon period is predicted based on multiple first beacon periods, the second beacon period is more accurate, the success rate of receiving a new beacon frame according to the second beacon period is higher, and the possibility of extending the opening time of the RF window is smaller. Therefore, the success rate of receiving beacon frames can be improved without increasing power consumption.

[0081] The embodiment of the present application provides a device for receiving a beacon frame, see Figure 7 ,The device includes the following modules.

[0082] An acquisition module 701 is configured to acquire a plurality of first beacon periods according to reception times of a plurality of received beacon frames, wherein any first beacon period among the plurality of first beacon periods is a difference between reception times of two adjacent received beacon frames;

[0089] In an exemplary embodiment, the weights corresponding to at least two first beacon periods among multiple first beacon periods are different; wherein, the difference between the reception time and the target time used to obtain two adjacent received beacon frames of any first beacon period is negatively correlated with the weight corresponding to any first beacon period.
