Description

Technical Field

[0001] The present invention relates to the field of TWS earphones, and particularly to a method, a system, an electronic device and a storage medium for controlling calls of TWS earphones. Background Art

[0002] With the development of true wireless stereo (TWS) technology and its application in the field of Bluetooth earphones, TWS earphones have emerged. Generally, the normal call process of Bluetooth earphones is as follows: The intelligent communication device sends Bluetooth call data packets to the Bluetooth earphone; the Bluetooth earphone receives the call data packets in the receiving window and the retransmission window; if the Bluetooth earphone does not receive the data packet in this window, or the received data packet has a CRC check error, then packet loss and packet loss compensation processing are performed.

[0003] For the TWS scenario, the connection method of TWS earphones is that the intelligent communication device first connects to the main earphone, and then the main earphone quickly connects to the sub - earphone wirelessly; after the intelligent communication device sends the call data packet, both earphones will receive it. If either earphone between the two earphones receives the correct call data packet, it is considered that the data packet is correctly received. However, if neither earphone receives it or both call data packets have CRC check errors, it is considered that the data packet reception fails, that is, packet loss compensation is required, and performing packet loss compensation will reduce the call quality. Summary of the Invention

[0027] Term Explanation:

[0028] TWS earphones: The full name of TWS is True Wireless Stereo, which means true wireless stereo. The TWS technology is developed based on Bluetooth chip technology. Its working principle is that the mobile phone connects to the main earphone, and then the main earphone quickly connects to the secondary earphone wirelessly, realizing the true wireless separation and use of the left and right Bluetooth channels.

[0029] Refer to Figure 1 , which is a flowchart of a method for controlling a TWS earphone call provided by an embodiment of the present invention, including but not limited to the following steps:

[0030] Step S100: The main earphone receives the first audio data, and the secondary earphone receives the second audio data.

[0031] Among them, the first audio data and the second audio data can be call data packets sent by the mobile phone, or other types of audio data sent by other electronic devices supporting Bluetooth communication technology. Taking the mobile phone as an example, the process of its communication with the TWS earphone is as follows: The mobile phone connects to the main earphone through a wireless connection method, sends the first data packet to the main earphone, and then the main earphone connects to the secondary earphone wirelessly and sends the first data packet sent by the mobile phone to the secondary earphone. Thus, the second audio data received by the secondary earphone is the first audio data forwarded by the main earphone.

[0032] Step S200: If both the first audio data and the second audio data are damaged, the secondary earphone sends the second audio data to the main earphone.

[0033] Among them, as receiving devices, both the main earphone and the secondary earphone need to check the received first audio data or second audio data. For example, cyclic redundancy check, that is, CRC check, is a data transmission error detection function. It calculates a polynomial for the data and attaches the obtained result to the back of the frame. The receiving device also executes a similar algorithm to ensure the correctness and integrity of data transmission; for the TWS scenario, taking the mobile phone as an example, after the mobile phone sends a data call packet, both the main earphone and the secondary earphone will receive it. If at least one of the two earphones receives the correct data packet, it is considered that the data packet is received correctly because the earphone that receives the correct data packet can forward the correct data packet to the other earphone. However, if both earphones do not receive it or an error occurs during the CRC check, it is considered that the data packet reception fails. Usually, the packet will be directly discarded and retransmitted at an appropriate time. However, in this embodiment, in the face of the situation where the data received by both ears is incorrect, it is not necessary to immediately perform packet loss compensation. Instead, the secondary earphone can send the second audio data to the main earphone, and the main earphone combines the first audio data and the second audio data to correct the incorrect data under appropriate circumstances.

[0034] Step S300: The master earphone compares the first audio data and the second audio data to obtain the abnormal data of the first audio data and the abnormal data of the second audio data.

[0035] Among them, when the data packet is correctly received, the first audio data received by the master earphone is exactly the same as the second audio data received by the slave earphone. Therefore, when the CRC checks of both audio data fail, after the master earphone receives the second audio data sent by the slave earphone, by comparing the first audio data and the second audio data, the abnormal data can be found, that is, the data that should be the same but is different in the two audio data, as well as the positions where these abnormal data appear. The abnormal data received by the master earphone is the abnormal data of the first audio data, and the abnormal data received by the slave earphone is the abnormal data of the second audio data.

[0036] Further, step S300 may include but is not limited to the following steps:

[0037] Step S301: If it is recognized that the first data existing in the first audio data is different from the second data existing in the second audio data, and the position of the first data in the first audio data is the same as the position of the second data in the second audio data, then the first data is recognized as the abnormal data of the first audio data, and the second data is recognized as the abnormal data of the second audio data.

[0038] Specifically, compare the first audio data and the second audio data bit by bit. If the data received by the master earphone and the slave earphone at a certain bit is different, that is, the first data at this bit in the first audio data is different from the second data at this bit in the second audio data, then the first data and the second data are extracted and used as the abnormal data of the first audio data and the abnormal data of the second audio data respectively, and the positions of these abnormal data in their respective audio data are obtained.

[0039] As an example, as shown in Table 1 below, the data in the first row is the original audio data sent by the mobile phone, where the last a9 and 25 are CRC check data. The data in the second row is the audio data received by the master earphone, that is, the first audio data, where e1 is misreceived as e0. The data in the third row is the audio data received by the slave earphone, that is, the second audio data, where 02 is misreceived as 00. By comparing the first audio data and the second audio data, it can be found that there are two bits where different data appears. At the first bit, the data received by the first audio data is 02, while the data received by the second audio data at this bit is 00. At the second bit, the data received by the first audio data is e0, while the data received by the second audio data at this bit is e1. Therefore, in this example, 02 and e0 are the abnormal data of the first audio data, and 00 and e1 are the abnormal data of the second audio data.

[0040] Table 1

[0041] 08 00 04 02 03ef 09e1 05 3b 8d 70……11 3e 55 78a9 25 08 00 04 02 03ef 09e0 05 3b 8d 70……11 3e 55 78a9 25 08 00 04 00 03ef 09e1 05 3b 8d 70……11 3e 55 78a9 25

[0042] Step S400: The master earphone updates the first audio data to obtain third audio data according to the abnormal data of the first audio data and the abnormal data of the second audio data, or updates the second audio data to obtain third audio data according to the abnormal data of the first audio data and the abnormal data of the second audio data.

[0043] Among them, after the master earphone finds the abnormal data in the first audio data and the second audio data by comparing the data of both ears, it can recover the original audio received according to the abnormal data. Since the receiving processes of the master earphone and the slave earphone are independent, the wrong bit positions of the received data may be different, which means that for the abnormal data of the same bit position, it is possible that one of the abnormal data is the correct data while the other is the wrong data. Therefore, these two abnormal data can be respectively substituted into the original audio data, that is, the first audio data or the second audio data, to obtain two pieces of third audio data, and then the third audio data is subjected to secondary verification. According to the verification results of these two pieces of third audio data, the correct data among these two abnormal data is found. However, if the bit positions where the master earphone and the slave earphone receive wrong data are the same, that is, the data of the first audio data and the second audio data at the same bit position are both wrong data, then the original data cannot be restored by exchanging the abnormal data, and a packet loss compensation operation needs to be performed subsequently.

[0044] Furthermore, step S400 may include but is not limited to the following steps:

[0045] Step S401: Recombine the abnormal data of the first audio data and the abnormal data of the second audio data to obtain fourth audio data.

[0046] Furthermore, step S401 may include but is not limited to the following steps:

[0047] Step S4011: If the position of the abnormal data of the first audio data in the first audio data is the same as the position of the abnormal data of the second audio data in the second audio data, select the abnormal data of the first audio data or the abnormal data of the second audio data as the data in the fourth audio data.

[0048] Specifically, abnormal data can be obtained through the above steps of comparing the audio data received by the main earphone and the sub-earphone. However, the abnormal data can only represent the differential data between the first audio data and the second audio data, and does not clearly indicate the data where the error occurs. Therefore, it is necessary to recombine the abnormal data of the first audio data and the abnormal data of the second audio data to obtain the fourth audio data. For each bit, select the abnormal data of the first audio data or the abnormal data of the second audio data as the candidate data that may be correct. Since there may be more than one bit where abnormal data appears, there may be more than one type of fourth audio data after recombination.

[0049] As an example, by comparing the first audio data and the second audio data in Table 1 above, the abnormal data 02 and e0 of the first audio data, and the abnormal data 00 and e1 of the second audio data are obtained. Among them, at the first bit, the abnormal data of the first audio data is 02, and the abnormal data of the second audio data is 00. At the second bit, the abnormal data of the first audio data is e0, and the abnormal data of the second audio data is e1. Based on this abnormal data, as shown in Table 2 below, two types of fourth audio data can be listed: First: Assume that 02 in the first audio data is correct and e0 is wrong. Therefore, select 02 as the candidate data at the first bit, and then select e1 in the second audio data as the candidate data at the second bit, thus obtaining the first row of data in Table 2 below; Second: Assume that 02 in the first audio data is wrong and e0 is correct. Therefore, select 00 in the second audio data as the candidate data at the first bit, and then select e0 in the first audio data as the candidate data at the second bit, thus obtaining the second row of data in Table 2 below. It should be noted that the number of combinations of the fourth audio data depends on how many abnormalities occur in the first audio data and the second audio data. The more abnormal data exists, the more combined data can be recombined.

[0050] Table 2

[0051] 02e1 00e0

[0052] Step S402: Replace the abnormal data of the first audio data with the fourth audio data to obtain the third audio data, or replace the abnormal data of the second audio data with the fourth audio data to obtain the third audio data.

[0053] Specifically, after obtaining several fourth audio data after recombining the abnormal data, according to the bit where the abnormal data is located, the data in the fourth audio data is replaced bit by bit with the abnormal data in the original data, thereby obtaining the third audio data. Since the data finally verified successfully by the main earphone and the sub-earphone is the same, either the first audio data or the second audio data can be selected to replace the abnormal data.

[0054] As an example, after replacing the first audio data or the second audio data with the fourth audio data in Table 2 above, the third audio data as shown in Table 3 below can be obtained.

[0055] Table 3

[0056] 08 00 04 02 03ef 09e1 05 3b 8d 70……11 3e 55 78a9 25 08 00 04 00 03ef 09e0 05 3b 8d 70……11 3e 55 78a9 25

[0057] Step S500: If the master earphone successfully verifies the third audio data, the master earphone sends the third audio data to the slave earphone.

[0058] Among them, after obtaining the third audio data through the above steps, it is necessary to verify each item of the third audio data one by one. After finding the third audio data with successful verification, the master earphone sends the third audio data to the slave earphone.

[0059] Furthermore, step S500 may include but is not limited to the following steps:

[0060] Step S501: Traverse the third audio data and perform CRC verification on each item of the third audio data one by one. If the verification is successful, the master earphone sends the third audio data to the slave earphone.

[0061] As an example, perform CRC verification on each row of data in Table 3 above. Through the verification, the first row of data that passes the CRC verification can be found and considered as the correct mobile phone transmission data, and the master earphone sends it to the slave earphone.

[0062] Through this method, the data received incorrectly by both the left and right ears is restored.

[0063] A method for controlling a TWS headphone call provided by an embodiment of the present invention may further include but is not limited to the following steps:

[0064] Step S600: If the verification of all the third audio data fails, both the master earphone and the slave earphone determine that the received data fails.

[0065] Specifically, if the data with successful CRC verification is found, it is considered that the data is the correct received data; if the third audio data with successful CRC verification cannot be found after traversing all combinations, it is determined that the data received by the master earphone and the slave earphone fails.

[0066] The embodiments of the present invention at least include the following beneficial effects: In the TWS call scenario, for the binaural data packets that both fail in CRC verification, instead of directly discarding them, useful data is restored through the cooperation of binaural data, thereby enhancing the call quality; Since the data reception processes of the master earphone and the slave earphone are independent, the bit positions where the received error data is located may be different. By finding the different data received by the master earphone and the slave earphone, all possible combinations of these data are brought into the original data, and secondary CRC verification is performed accordingly, and the correct data packets are restored, and some of the received error data packets are corrected, which can improve the call quality and can make full use of the characteristic that the two earphones of TWS receive data independently, and achieve the advantage of diversity reception bit by bit.

[0067] Step S700: If the verification of the third audio data is successful, the master earphone reports the third audio data.
