[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] It should be noted that the terms "first", "second", "third" and "fourth" in the specification and claims of the present application are used to distinguish different objects rather than to describe a specific order. The terms "including" and "having" in the embodiments of the present application and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] The embodiments of the present application disclose a communication method and device, an electronic device, and a computer-readable storage medium, which can improve the accuracy of communication channel selection, thereby avoiding the impact of channel interference on data transmission.

[0036] The technical solution of the present application will be described in detail below in conjunction with specific embodiments.

[0037] In order to more clearly explain a communication method disclosed in an embodiment of the present application, an application scenario applicable to the method is first introduced. Figure 1 , Figure 1 1 is a schematic diagram of an application scenario disclosed in an embodiment of the present application. Optionally, the method can be applied to the first electronic device 110, which can be various electronic devices with certain communication capabilities, including but not limited to: portable electronic devices such as mobile phones and tablet computers, wearable devices such as headphones and smart watches, or desktop electronic devices such as speakers, desktop computers, and desktop TVs, which are not limited here. Figure 1 The use of "speaker" to represent the first electronic device 110 is only an optional example. Figure 1This should not be construed as limiting the embodiments of the present application.

[0038] Optionally, the second electronic device 120 can establish communication connections with multiple electronic devices 130 at the same time. The communication connections may include but are not limited to Bluetooth communication connections, WI-FI communication connections, etc., which are not limited here. The multiple electronic devices 130 are in a synchronous broadcast state. The first electronic device 110 can be any one of the multiple electronic devices 130. It should be noted that the synchronous broadcast state refers to a state in which multiple electronic devices 130 respectively receive broadcast data sent by the second electronic device 120 and play the broadcast data respectively.

[0039] In the field of Bluetooth technology, one application scenario of Bluetooth LE Audio technology is Broadcast Audio technology, which enables an audio source device to broadcast broadcast data to one or more audio receiving devices at the same time. Optionally, when the second electronic device 120 establishes a Bluetooth connection with multiple electronic devices 130, the second electronic device 120 can act as a data transmitter and send the broadcast data to multiple electronic devices 130 respectively, and then the multiple electronic devices 130 acting as data receivers can synchronously output the audio corresponding to the broadcast data.

[0040] In practice, it is found that the second electronic device 120 can usually only determine a communication channel with better quality among multiple communication channels based on its own quality evaluation results of the communication channels to send broadcast data to the first electronic device 110. However, due to differences in hardware and the environment in which they are located, the second electronic device 120 and the first electronic device 110 may have different quality evaluation results for the communication channels, resulting in the communication channel that the second electronic device 120 considers to have better quality being used, which may be subject to strong interference at the end of the first electronic device 110, thereby affecting the reception quality of the broadcast data.

[0041] In this regard, the present application discloses a communication method to solve the above technical problems. Figure 2 , Figure 2 It is a timing diagram disclosed in an embodiment of the present application. Optionally, the second electronic device 120 can send broadcast data 210 to the first electronic device 110 and other electronic devices 140 respectively; wherein the other electronic devices 140 are any electronic devices other than the first electronic device 110 among the above-mentioned multiple electronic devices 130. Further, the second electronic device 120 can send first control information 220 to the first electronic device 110 and other electronic devices 140 respectively; and then the first electronic device 110 and other electronic devices 140 can determine whether their own channel assessment results are updated when receiving the first control information 220.

[0042] Optionally, when the first electronic device 110 determines that the first channel assessment result corresponding to itself is updated, it can send the updated first channel assessment result 230 to the second electronic device 120; then the second electronic device 120 determines whether the updated first channel assessment result 230 is received, and if the updated first channel assessment result 230 is successfully received, it feeds back confirmation information 240 to the first electronic device 110, and then the first electronic device 110, when receiving the confirmation information 240, can wait for the second electronic device 120 to feed back update information 250. Optionally, the second electronic device 120 can determine whether to update the communication channel for broadcast data transmission with the first electronic device 110 according to the updated first channel assessment result 230; if it needs to be updated, it sends the update information 250 to the first electronic device 110; when the first electronic device 110 receives the update information 250, it can switch to the target communication channel indicated by the update information 250.

[0043] Optionally, when other electronic devices 140 receive the first control information 220 and determine that their corresponding channel assessment results have not been updated, they may not feed back the channel assessment results to the second electronic device 120 and continue to wait to receive data sent by the second electronic device 120.

[0044] It can be seen that in the embodiment of the present application, the second electronic device 120 that sends broadcast data can combine the real-time first channel evaluation result of the first electronic device 110 to determine a target communication channel that is more conducive to the transmission of broadcast data, thereby avoiding the impact of channel interference on data transmission and improving the transmission quality of the broadcast data; and, the first electronic device 110 only feeds back the first channel evaluation result when its own first channel evaluation result is updated, which can also reduce the number of meaningless channel evaluation result feedbacks and save transmission resources and power consumption of the first electronic device; in addition, when the first electronic device 110 updates its own first channel evaluation result, the feedback of the updated first channel evaluation result triggers the second electronic device 120 to re-judge whether to update the communication channel for broadcast data transmission with the first electronic device 110, and can also continuously maintain the best quality communication channel between the first electronic device 110 and the second electronic device 120, further improving the transmission quality of the broadcast data.

[0045] Based on this, the communication method and device, electronic device, and computer-readable storage medium disclosed in the embodiments of the present application are introduced below.

[0046] See also Figure 3 , Figure 31 is a flow chart of a communication method disclosed in an embodiment of the present application. Optionally, the method can be applied to the first electronic device mentioned above, and the first electronic device can be connected to the second electronic device for communication. Optionally, the method can include the following steps:

[0047] 302. When a first channel assessment result corresponding to the first electronic device is updated, the updated first channel assessment result is sent to the second electronic device, and the updated first channel assessment result is used to instruct the second electronic device to determine whether to update the communication channel for broadcast data transmission with the first electronic device based on the updated first channel assessment result.

[0048] In an embodiment of the present application, the first channel evaluation result is used to reflect the communication quality of multiple communication channels corresponding to the first electronic device. Optionally, the first channel evaluation result may include at least one of the useful signal strength (Packet RSSI), noise strength (Noise RSSI) or signal-to-noise ratio information corresponding to the multiple communication channels corresponding to the first electronic device.

[0049] It should be noted that after receiving the data, the electronic device can determine the strength of the useful signal of the currently used communication channel (Packet RSSI) based on the signal strength of the received data; and the electronic device can detect the noise strength of each communication channel through a noise detection method to obtain the noise strength (NoiseRSSI) corresponding to each communication channel; optionally, the electronic device can also determine the signal-to-noise ratio information corresponding to each communication channel based on the strength of the useful signal and the noise strength corresponding to each communication channel, and the signal-to-noise ratio information can be used to indicate the communication quality of the corresponding communication channel.

[0050] Optionally, the first electronic device may obtain the current first channel assessment result, and compare the current first channel assessment result with the historical first channel assessment result to determine whether the first channel assessment result is updated. Optionally, if the first channel assessment result is updated, the first electronic device may feed back the updated first channel assessment result to the second electronic device.

[0051] Optionally, since the communication quality of the communication channel does not change frequently, the first electronic device can obtain the current first channel evaluation result once per unit time interval to save power consumption of the first electronic device. In another optional embodiment, the first electronic device can obtain the current first channel evaluation result when in an idle state to avoid affecting the first electronic device from performing other functions.

[0052] Optionally, the first electronic device may send an updated first channel evaluation result to the second electronic device through a communication connection established between the first electronic device and the second electronic device. In other optional embodiments, when the first electronic device and the second electronic device are in a broadcast state, since the second electronic device, as a sender of broadcast data, can only send broadcast data to the first electronic device unidirectionally, the first electronic device cannot feed back the updated first channel evaluation result to the second electronic device in the form of broadcast data. The broadcast data may include broadcast data based on the communication standard of Bluetooth low energy audio, including but not limited to Broadcast Isochronous Group (BIG), Broadcast Isochronous Stream (BIS), etc., which are not limited here. Please refer to Figure 4 , Figure 4 It is a data structure diagram of a broadcast data disclosed in an embodiment of the present application. Optionally, a synchronous broadcast group 410 may include one or more synchronous broadcast streams 420, wherein a synchronous broadcast stream 420 may include one or more sub-events 4201. Optionally, each synchronous broadcast group 410 may also include a control sub-event 430, and the control sub-event 430 is used to determine the transmission method of the corresponding broadcast data, such as: the communication channel adopted, the data encapsulation format, etc., which are not limited here. It should be further explained that the synchronous broadcast group 410 does not necessarily include the control sub-event 430, that is, some synchronous broadcast groups 410 may not include the control sub-event 430, which is not limited here.

[0053] Since the first electronic device can also feed back control sub-events to the second electronic device in the broadcasting state, in this embodiment of the present application, the first electronic device can send the updated first channel evaluation result to the second electronic device in the form of control sub-events, thereby achieving the effect of "two-way control information transmission method of one-way synchronous broadcast", that is, the second electronic device can send broadcast data to the first electronic device unidirectionally, but control sub-events can be transmitted bidirectionally between the second electronic device and the first electronic device, so that the second electronic device can obtain the real-time communication channel evaluation status fed back by the first electronic device.

[0054] Furthermore, when the second electronic device receives the updated first channel evaluation result, it can determine whether to update the communication channel for broadcast data transmission with the first electronic device based on the updated first channel evaluation result. Optionally, the second electronic device can determine one or more first communication channels with communication quality higher than the first threshold in the updated first channel evaluation result; further, if the communication channel currently used by the second electronic device and the first electronic device does not match the first communication channel, it is determined that the communication channel for broadcast data transmission with the first electronic device needs to be updated; if the communication channel currently used by the second electronic device and the first electronic device matches the first communication channel, it can be determined that the communication channel for broadcast data transmission with the first electronic device does not need to be updated.

[0055] As an optional implementation, the second electronic device can determine whether to update the communication channel for broadcast data transmission with the first electronic device based on the updated first channel evaluation result and the second channel evaluation result corresponding to the second electronic device. The second channel evaluation result is used to reflect the communication quality of multiple communication channels corresponding to the second electronic device. Optionally, the second channel evaluation result may include at least one of the strength of the useful signal (Packet RSSI), the noise intensity (Noise RSSI) or the signal-to-noise ratio information corresponding to the multiple communication channels corresponding to the second electronic device. The second channel evaluation result is similar to the content of the above-mentioned first channel evaluation result, and will not be repeated here.

[0056] It should be noted that due to differences in hardware, environment, etc., the second electronic device and the first electronic device may have different quality assessment results for the communication channel. The second channel assessment result may or may not be the same as the first channel assessment result, which is not limited here.

[0057] Optionally, the second electronic device can determine one or more second communication channels whose communication quality is higher than a second threshold value from the updated first channel evaluation results and the second channel evaluation results; and then, if the communication channel currently used by the second electronic device and the first electronic device does not match the second communication channel, it is determined that the communication channel for broadcast data transmission with the first electronic device needs to be updated; if the communication channel currently used by the second electronic device and the first electronic device matches the second communication channel, it can be determined that the communication channel for broadcast data transmission with the first electronic device does not need to be updated.

[0058] By implementing the above method, the second electronic device serving as the data sending end can determine whether to update the communication channel for broadcast data transmission with the first electronic device based on its own channel evaluation result and the updated real-time channel evaluation result of the first electronic device serving as the data receiving end, thereby determining a target communication channel that is more conducive to broadcast data transmission, avoiding the impact of channel interference on data transmission, and improving the transmission quality of broadcast data.

[0059] By implementing the method disclosed in the above embodiments, when the first electronic device detects that its first channel evaluation result is updated, it can actively send the updated first channel evaluation result to the second electronic device, so that the second electronic device can determine whether to update the communication channel for broadcast data transmission with the first electronic device in combination with the real-time first channel evaluation result of the first electronic device. It can be seen that in the embodiment of the present application, the second electronic device that sends broadcast data can determine the target communication channel that is more conducive to broadcast data transmission in combination with the real-time first channel evaluation result of the first electronic device, thereby avoiding the influence of channel interference on data transmission and improving the transmission quality of broadcast data; and, the first electronic device only feeds back the first channel evaluation result when its first channel evaluation result is updated, which can avoid meaningless feedback times of channel evaluation results and save transmission resources and power consumption of the first electronic device; in addition, when the first electronic device feeds back the updated first channel evaluation result when its first channel evaluation result is updated, it triggers the second electronic device to re-determine whether to update the communication channel for broadcast data transmission with the first electronic device, and can also continuously maintain the best quality communication channel between the first electronic device and the second electronic device, further improving the transmission quality of broadcast data.

[0060] See also Figure 5 , Figure 5 1 is a flow chart of another communication method disclosed in an embodiment of the present application. Optionally, the method can be applied to the first electronic device mentioned above, and the first electronic device can be connected to the second electronic device for communication. Optionally, the method can include the following steps:

[0061] 502. Receive first control information sent by a second electronic device, where the first control information is used to determine a transmission method for broadcast data.

[0062] In the embodiment of the present application, the second electronic device can send broadcast data to the first electronic device in the broadcast state, and the broadcast data can include broadcast audio data (such as the form of "synchronous broadcast stream" mentioned above) and control sub-events. Optionally, the first control information can include the above-mentioned control sub-event, and the control sub-event is used to instruct the second electronic device how to send the broadcast data. The control sub-event has been introduced above and will not be repeated here.

[0063] 504. In response to the first control information, determine whether a first channel assessment result corresponding to the first electronic device is updated.

[0064] Please refer again Figure 4 Optionally, the control sub-event 430 is usually at the end of the synchronous broadcast group 410. When the second electronic device sends a group of broadcast data to the first electronic device, the first electronic device first receives one or more broadcast audio data, and finally receives the control sub-event corresponding to the group of broadcast data. That is, the first electronic device may receive a control sub-event every time it receives a group of broadcast data. Optionally, the control sub-event can be used as a condition to trigger the first electronic device to determine whether the first channel evaluation result corresponding to the first electronic device is updated, so that the second electronic device does not need to send specific trigger information to trigger the first electronic device to determine whether the first channel evaluation result corresponding to the first electronic device is updated, thereby saving the transmission overhead of the second electronic device; in addition, due to the structural characteristics of the broadcast data, the first electronic device usually receives a control sub-event at an interval of time, thereby triggering an update judgment, so that the first electronic device will not always be in an update judgment state, saving the power consumption of the first electronic device; in addition, the first electronic device receives the control sub-event relatively frequently, so that the first electronic device can promptly determine whether the first channel evaluation result is updated, and promptly feed back the update result to the second electronic device, so that the second electronic device can determine the target communication channel that is more conducive to the transmission of broadcast data based on the first channel evaluation result that best meets the current actual situation, thereby avoiding the impact of channel interference on data transmission and improving the transmission quality of broadcast data.

[0065] 506. When the first channel evaluation result corresponding to the first electronic device is updated, the updated first channel evaluation result is sent to the second electronic device, and the updated first channel evaluation result is used to instruct the second electronic device to determine whether to update the communication channel for broadcast data transmission with the first electronic device based on the updated first channel evaluation result.

[0066] As an optional implementation, when the first channel evaluation result corresponding to the first electronic device is updated, the current communication channel currently used by the first electronic device and the second electronic device can be obtained, and the communication quality currently corresponding to the current communication channel can be determined in the updated first channel evaluation result; if the communication quality currently corresponding to the current communication channel is less than or equal to the first quality threshold, the updated first channel evaluation result is sent to the second electronic device; if the communication quality currently corresponding to the current communication channel is greater than the first quality threshold, the updated first channel evaluation result may not be sent to the second electronic device.

[0067] It can be understood that if the communication quality of the communication channel currently used by the first electronic device and the second electronic device is less than or equal to the first quality threshold in the first channel evaluation result most recently updated by the first electronic device, it means that the currently used communication channel is not optimal, so the updated first channel evaluation result is sent to the second electronic device to trigger the second electronic device to update the communication channel, thereby improving the data transmission quality between the two; if the communication quality currently corresponding to the current communication channel is greater than the first quality threshold, the updated first channel evaluation result may not be sent to the second electronic device to save power consumption of the first electronic device.

[0068] As another optional implementation, when the first channel evaluation result corresponding to the first electronic device is updated, the first electronic device can determine a third communication channel whose communication quality is greater than or equal to the second quality threshold in the updated first channel evaluation result, and send the third communication channel to the second electronic device, so that the second electronic device determines whether to update the communication channel for broadcast data transmission with the first electronic device based on the third communication channel.

[0069] It can be understood that the first electronic device can only feed back the third communication channel with better current communication quality to the second electronic device, so that the second electronic device can select the target communication channel to be used subsequently from the third communication channel to improve the data transmission quality between the two; in addition, only feeding back the third communication channel can reduce the amount of data fed back by the first electronic device to the second electronic device, thereby saving the transmission resources and power consumption of the first electronic device.

[0070] By implementing the methods disclosed in the above embodiments, the second electronic device that sends broadcast data can determine a target communication channel that is more conducive to broadcast data transmission in combination with the real-time first channel evaluation result of the first electronic device, thereby avoiding the impact of channel interference on data transmission and improving the transmission quality of the broadcast data; and the first electronic device only feeds back the first channel evaluation result when its own first channel evaluation result is updated, thereby avoiding meaningless feedback times of the channel evaluation result and saving transmission resources and power consumption of the first electronic device; in addition, when the first channel evaluation result of the first electronic device is updated, the first electronic device feeds back the updated first channel evaluation result to trigger the second electronic device to re-determine whether to update the communication channel for broadcast data transmission with the first electronic device, and can also continuously maintain the best quality communication channel between the first electronic device and the second electronic device, further improving the transmission quality of the broadcast data; and the control sub-event can be used as a condition for triggering the first electronic device to determine whether the first channel evaluation result corresponding to the first electronic device is updated, so that the second electronic device does not need to send specific trigger information to trigger the first electronic device to determine whether the first channel evaluation result corresponding to the first electronic device is updated, thereby saving the transmission overhead of the second electronic device.

[0071] See also Figure 6 , Figure 6 1 is a flow chart of another communication method disclosed in an embodiment of the present application. Optionally, the method can be applied to the first electronic device mentioned above, and the first electronic device can be connected to the second electronic device for communication. Optionally, the method can include the following steps:

[0072] 602. When a first channel assessment result corresponding to the first electronic device is updated, the updated first channel assessment result is sent to the second electronic device, and the updated first channel assessment result is used to instruct the second electronic device to determine whether to update the communication channel for broadcast data transmission with the first electronic device based on the updated first channel assessment result.

[0073] In an embodiment of the present application, after the first electronic device sends an updated first channel assessment result to the second electronic device, if the second electronic device successfully receives the updated first channel assessment result, the second electronic device may feedback confirmation information to the first electronic device, and the confirmation information is used to indicate that the second electronic device has successfully received the updated first channel assessment result.

[0074] Correspondingly, if the second electronic device does not receive the updated first channel assessment result, it does not feed back confirmation information to the first electronic device.

[0075] In this regard, as an optional implementation, when the first electronic device sends an updated first channel assessment result to the second electronic device, if the first electronic device does not receive confirmation information fed back by the second electronic device, the first electronic device may resend the updated first channel assessment result to the second electronic device until the confirmation information is received and then stop updating the first channel assessment result.

[0076] Among them, considering that it takes a certain amount of time for the second electronic device to feed back confirmation information to the first electronic device, optionally, after sending the updated first channel assessment result, the first electronic device can wait for a first period of time. If the confirmation information fed back by the second electronic device is not received within the first period of time, the first electronic device can resend the updated first channel assessment result to the second electronic device until the confirmation information is received before stopping the updated first channel assessment result. Among them, the first period of time can be set by the developer based on a lot of development experience and is not limited here.

[0077] By implementing the above method, the first electronic device and the second electronic device can determine whether the second electronic device has successfully received the updated first channel assessment result through confirmation information, wherein if the first electronic device does not receive the confirmation information, the updated first channel assessment result can be retransmitted to the second electronic device, thereby ensuring that the second electronic device can receive the updated first channel assessment result corresponding to the first electronic device.

[0078] 604. If the update information sent by the second electronic device is received, switch the first electronic device to the target communication channel indicated by the update information.

[0079] In the embodiment of the present application, when the second electronic device receives the updated first channel evaluation result, if it is determined that it needs to switch to the target communication channel according to the updated first channel evaluation result, it can send update information to the first electronic device, and the update information may include a switching instruction and target communication channel information, which is not limited here. Among them, the switching instruction is used to indicate whether the first electronic device needs to update the communication channel, and the target communication channel information may include the identification and number of the target communication channel and other information used to identify the target communication signal.

[0080] Optionally, when the first electronic device receives the update information, it can parse the update information to obtain a switching instruction.
