[0068] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0069] In the related art, when an abnormality occurs in a wireless access point, an incorrect beacon frame may be sent to a terminal device. Even when there is no cached data to be sent to the terminal device, the identification information in the beacon frame indicates the existence of cached data. After receiving this identification information, the terminal device frequently wakes up a specific program, such as the fireware program in the wireless chip, to request cached data from the wireless access point, thereby increasing the power consumption of the terminal device and causing abnormal power consumption of the terminal device.

[0070] In an exemplary embodiment of the present disclosure, in order to overcome the problems in the related art, a communication method is provided, which is applied to a terminal device. The terminal device receives identification information sent by a wireless access point according to a preset interval period. The identification information is used to indicate whether there is cached data in the wireless access point to be sent to the terminal device. When the terminal device determines according to the identification information that there is cached data in the wireless access point to be sent to the terminal device, it sends a data request to the wireless access point, and adjusts the preset interval period and / or the reception duration of each reception of the identification information according to the data request result. It is possible to dynamically adjust the preset interval period and / or the reception duration of the terminal device for receiving the identification information according to the data request result, thereby reducing the power consumption loss when the radio frequency front end of the terminal device is powered on when no data is requested, and the power consumption loss caused by frequent data requests, avoiding the situation of abnormal power consumption of the terminal device, and maintaining the normal power-on frequency of the radio frequency front end when data is requested to ensure that the terminal device can normally perform data requests.

[0071] In an exemplary embodiment of the present disclosure, a communication method is provided, which is applied to a terminal device. The terminal device includes electronic devices with wireless communication functions such as mobile phones, tablets, and smart wearable devices. Figure 1 is a flowchart of a communication method shown according to an exemplary embodiment, as Figure 1 shown, the communication method includes the following steps:

[0072] Step S101, receiving identification information sent by a wireless access point according to a preset interval period, where the identification information is used to indicate whether there is cached data in the wireless access point to be sent to the terminal device;

[0073] Step S102, when it is determined according to the identification information that there is cached data in the wireless access point to be sent to the terminal device, sending a data request to the wireless access point;

[0074] Step S103, adjusting the preset interval period and / or the reception duration of each reception of the identification information according to the data request result.

[0075] In step S101, after the terminal device connects to the wireless network, the wireless access point communicates with the terminal device by sending beacon frames. The beacon frames include identification information TIM (Traffic Indication Map, data to-be-transmitted information), and the identification information TIM is used to indicate whether there is buffered data in the wireless access point to be sent to the terminal device. Exemplarily, when the association identifier (AID) corresponding to the current terminal device in the identification information is 1, it indicates that there is buffered data in the wireless access point to be sent to the current terminal device; when the association identifier corresponding to the current terminal device in the identification information is 0, it indicates that there is no buffered data in the wireless access point to be sent to the current terminal device. The terminal device powers on the radio frequency front end of the signal receiving device at a preset interval period and receives the beacon frame through the radio frequency front end to receive the identification information. The receiving duration of the identification information is a fixed preset duration.

[0076] The initial preset interval period and the initial receiving duration of receiving the identification information are both fixed durations in the existing protocol. Figure 2 is a schematic diagram of the preset interval period and the receiving duration of receiving the identification information shown according to an exemplary embodiment, as Figure 2 shown, the preset interval period is T1, and the receiving duration of receiving the identification information is T2.

[0077] In step S102, when the terminal device determines, according to the received identification information, that there is buffered data in the wireless access point to be sent to the terminal device, that is, when the AID corresponding to the current device in the identification information TIM in the beacon frame is 1, the terminal device wakes up a specific program in its own wireless chip to send a data request to the wireless access point. For example, it wakes up the firmware program of the wireless chip to send a PS-POLL (Power Save-Poll) to the wireless access point.

[0078] In step S103, after the wireless access point receives the data request, if there is no buffered data in the wireless access point to be sent to the terminal device, it will not send the buffered data to the terminal device. If there is buffered data in the wireless access point to be sent to the terminal device, it will send the buffered data to the terminal device according to the data request. The terminal device determines the interval period and the receiving duration of receiving the identification information according to the data request result. When the data request result is that the buffered data is requested, the preset interval period and the receiving duration of receiving the identification information are not adjusted; when the data request result is that the buffered data is not requested, the preset interval period and / or the receiving duration of receiving the identification information are adjusted, and the adjustment rule can be determined according to actual requirements.

[0079] In an exemplary embodiment of the present disclosure, the terminal device receives identification information sent by a wireless access point at a preset interval period. When it is determined that there is buffered data in the wireless access point to be sent to the terminal device according to the received identification information, a data request is sent to the wireless access point, and the preset interval period and / or the reception duration of receiving the identification information are adjusted according to the data request result, so that the preset interval period and / or the reception duration of the terminal device receiving the identification information can be dynamically adjusted according to the data request result. Since the radio frequency front end of the terminal device needs to be powered on when receiving the identification information, therefore, dynamically adjusting the preset interval period and / or the reception duration of receiving the identification information can reduce the power consumption loss of the terminal device when the radio frequency front end is powered on, thereby avoiding the abnormal power consumption of the terminal device.

[0080] In an exemplary embodiment, adjusting the preset interval period and / or the reception duration of receiving the identification information each time according to the data request result in step S103 includes the following three cases:

[0081] First, when the data request result is that no buffered data is requested, the preset interval period is extended based on a first preset policy.

[0082] Second, when the data request result is that no buffered data is requested, the reception duration is shortened based on a second preset policy.

[0083] Third, when the data request result is that no buffered data is requested, the preset interval period is extended based on a first preset policy, and at the same time the reception duration is shortened based on a second preset policy.

[0084] When the terminal device does not request buffered data, the preset interval period for receiving the identification information can be extended based on a first preset policy, the reception duration of receiving the identification information can be shortened based on a second preset policy, or the preset interval period can be extended based on a first preset policy and the reception duration can be shortened based on a second preset policy at the same time. The first preset policy and the second preset policy can be set according to actual needs.

[0085] It should be noted that when the terminal device does not request buffered data, the preset interval period and / or the reception duration can be adjusted immediately, or the preset interval period and / or the reception duration can be adjusted when the terminal device fails to request buffered data continuously for multiple times, or after adjusting the preset interval period and / or the reception duration and still not requesting buffered data, the preset interval period and / or the reception duration can be adjusted continuously. Figure 3 is a schematic diagram of the extended preset interval period and the shortened reception duration shown according to an exemplary embodiment, as Figure 3The extended preset interval periods shown are t11, t12, and t13 respectively, and the shortened receiving durations are t21, t22, t23, and t24 respectively, where t11 < t12 < t13 and t21 > t22 > t23 > t24.

[0086] In an exemplary embodiment, Figure 4 is a flowchart of a method for extending a preset interval period based on a first preset policy shown according to an exemplary embodiment, as Figure 4 shown, and includes the following steps:

[0087] Step S401, determining the number information of continuously sending data requests to a wireless access point and not requesting data;

[0088] Step S402, determining the extended preset interval period according to the number information.

[0089] When the terminal device sends a data request to the wireless access point according to the identification information and the request result is that no cached data is requested, record an abnormal identification information once. Determine the number of consecutive abnormal identification information, and determine the extended preset interval period according to the number. For example, according to the wireless network transmission traffic indication message (DTIM) period, determine that the preset interval period is DTIM. When the consecutive number is N times, the extended preset period is set to N * DTIM.

[0090] In an exemplary embodiment, Figure 5 is a flowchart of a method for determining the extended preset interval period according to the number information in step S402 shown according to an exemplary embodiment, as Figure 5 shown, and includes the following steps:

[0091] Step S501, determining the extended initial interval period according to the number information;

[0092] Step S502, if the initial interval period is less than the interval period threshold, determine the initial interval period as the extended preset interval period;

[0093] Step S503, if the initial interval period is greater than or equal to the interval period threshold, determine the interval period threshold as the extended preset interval period.

[0094] The extended preset interval period determined according to the number of times of continuously sending data requests to the wireless access point without obtaining data is the extended initial interval period. To ensure the normal connection between the terminal device and the wireless network, there is a maximum interval period threshold for the preset interval period of receiving identification information. When the interval period of receiving identification information is greater than the maximum interval period threshold, it will cause the terminal device to disconnect from the wireless network. After determining the extended initial interval period, if the initial interval period is less than the interval period threshold, the initial interval period is determined as the extended preset interval period; if the initial interval period is greater than or equal to the interval period threshold, the interval period threshold is determined as the extended preset interval period. Exemplarily, when the extended initial interval period is N*DTIM and the interval period threshold is MaxTime, the extended preset interval period is min(N*DTIM, MaxTime), that is, the smaller value between the extended initial interval period and the interval period threshold.

[0095] In an exemplary embodiment, Figure 6 is a flowchart of a method for shortening the reception duration based on a second preset policy shown according to an exemplary embodiment, as Figure 6 shown, and includes the following steps:

[0096] Step S601, determining the number information of continuously sending data requests to the wireless access point without obtaining data;

[0097] Step S602, determining the shortened reception duration according to the number information.

[0098] When the terminal device sends a data request to the wireless access point according to the identification information and the request result is that no cached data is obtained, one abnormal identification information is recorded. Determine the number of consecutive abnormal identification information, and determine the reception duration of the shortened received identification information according to the number. For example, when the reception duration of receiving the identification information is T2 and the consecutive number is N times, the shortened reception duration is T2 / N.

[0099] In an exemplary embodiment, Figure 7 is a flowchart of a method for determining the shortened reception duration according to the number information in step S602 shown according to an exemplary embodiment, as Figure 7 shown, and includes the following steps:

[0100] Step S701, determining the shortened initial reception duration according to the number information;

[0101] Step S702, if the initial reception duration is greater than or equal to the reception duration threshold, determining the initial reception duration as the shortened reception duration;

[0102] Step S703, if the initial reception duration is less than the reception duration threshold, then determine the reception duration threshold as the shortened reception duration.

[0103] The reception duration of the shortened reception identification information determined according to the number of times of continuously sending data requests to the wireless access point without successfully requesting data is the shortened initial reception duration. To ensure that the terminal device can receive the identification information normally, there is a minimum reception duration threshold for receiving the identification information. When the reception duration of the identification information is less than the minimum reception duration threshold, the terminal device cannot receive the identification information normally. After determining the shortened initial reception duration, if the initial reception duration is less than the reception duration threshold, then determine the reception duration threshold as the shortened reception duration; if the initial reception duration is greater than or equal to the reception duration threshold, then determine the initial reception duration as the shortened reception duration. Exemplarily, when the shortened initial reception duration is T2 / N and the reception duration threshold is MinTime, then the shortened reception duration is max(T2 / N, MinTime), that is, the larger value between the shortened initial reception duration and the reception duration threshold.

[0104] In an exemplary embodiment, after adjusting the preset interval period and / or the reception duration for each reception of the identification information according to the data request result, the communication method further includes: when data is successfully requested, restore the preset interval period and the reception duration to the values before adjustment.

[0105] When the terminal device sends a data request to the wireless access point and successfully requests data, it indicates that the wireless access point is in a normal state. At this time, restore the preset interval period and the reception duration for receiving the identification information to the values before adjustment. The restoration time can be immediately restored when sending a data request to the wireless access point and successfully requesting data, or restored when continuously sending data requests to the wireless access point multiple times and successfully requesting data.

[0106] In an exemplary embodiment of the present disclosure, a communication method is provided, which is applied to a terminal device. Figure 8 is a flowchart of a communication method shown according to an exemplary embodiment, as Figure 8 shown, the communication method includes the following steps:

[0107] Step S801, receive the identification information sent by the wireless access point according to the preset interval period;

[0108] wherein, the identification information is used to indicate whether there is cached data in the wireless access point to be sent to the terminal device.

[0109] Step S802, determine whether there is cached data in the wireless access point to be sent to the terminal device according to the identification information;

[0110] If yes, execute step S803; if no, execute step S801.

[0111] Step S803: Send a data request to the wireless access point.

[0112] Step S804: Determine whether data is requested successfully.

[0113] If data is requested successfully, execute step S801; if data is not requested successfully, execute step S805.

[0114] Step S805: Adjust the preset interval period and / or the receiving duration for each received identification information.

[0115] Extend the preset interval period based on the first preset policy, and / or shorten the receiving duration based on the second preset policy.

[0116] Step S806: When data is requested successfully, restore the preset interval period and the receiving duration to the values before adjustment.
