The data transmission method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1, the present embodiment provides a data transmission method applied to a master earphone, which may include the following steps, which are described in detail below.

In step 1100, a first data packet sent by an electronic device is received.

In this embodiment, the first data packet may be transmitted by the electronic device through the first signal link. The first packet may be Audio data (Advanced Audio Distribution Profile, A2 DP). The first signal link is a communication link established between the primary earpiece and the electronic device.

The first data packet may be divided into a plurality of first data segments. The finer the granularity of the first packet division, i.e., the more the first data segment is divided, the smaller the amount of data to be retransmitted when a packet loss occurs. Similarly, the finer the granularity of the first packet partition is, the greater the amount of processing required during verification.

In one embodiment, the first data packet is divided into a plurality of first data segments according to the setting parameters. Wherein the setting parameter is determined according to the time slot of the transmission data. That is, the division may be made by time slots of data transmission. Illustratively, the division is by 1 slot, i.e. each slot corresponds to one first data segment. For example, as shown in fig. 2, a first data packet is received through 5 time slots, and the first data packet is divided into 5 first data segments, that is, a time slot N +1, a time slot N +2, a time slot N +3, and a time slot N +4 correspond to one first data segment respectively. Illustratively, the division may also be made in 1/2 time slots. Also for example, the division may be made in 1/4 time slots. Illustratively, the division may also be made in 2 slots. In this embodiment, the first data packet may be divided according to actual needs, so as to reduce the data processing amount during checking while improving the retransmission efficiency.

After step 1100, step 1200 is executed to check the first data packet, so as to obtain a first check result.

In this embodiment, the checking the first data packet may include checking the integrity of the received first data packet to obtain first checking information. The checking of the first data packet may further include splitting the first data packet, and checking each first data segment of the first data packet to obtain a first check code corresponding to each first data segment. The first check result includes first check information indicating whether the first data packet is complete and a first check code of each of the plurality of first data segments. Continuing with fig. 2 as an example, the first data packet is divided into 5 first data segments according to the time slot, and each first data segment corresponds to obtain a first check code. Based on the first check information, it may be determined whether the first data packet is complete, i.e. whether the first data packet fails to be transmitted. It may further be determined which of the first data segments in the first data packet failed to be transmitted based on the first check code.

It will be appreciated that the first packet may be checked in a Cyclic Redundancy Check (CRC) Check, such as CRC-32. The first data packet may be checked in a parity check. The embodiment of the present application does not limit the checking method of the first data packet.

After step 1200, step 1300a is executed to send the first verification result to the slave earphone, so that the slave earphone determines the data segment which is failed to be transmitted in the first data packet according to the first verification result and the second verification result of the second data packet, and receives the second data segment which is sent by the slave earphone and corresponds to the data segment which is failed to be transmitted in the first data packet.

In this embodiment, the second data packet may be obtained by the slave earphone by monitoring a signal link between the master earphone and the electronic device when the master earphone receives the first data packet sent by the electronic device. The second packet is a packet corresponding to the first packet. The second data packet is divided into a plurality of second data segments, and the plurality of second data segments correspond to the plurality of first data segments one to one.

The finer the granularity of the division of the second data packet, i.e., the more the divided second data segment, the smaller the amount of data to be retransmitted when a packet loss occurs. Similarly, the finer the granularity of the second packet partition, the greater the amount of processing required for verification.

In one embodiment, the second data packet is divided into a plurality of second data segments according to the setting parameters. Wherein the setting parameter is determined according to the time slot of the transmission data. That is, it may be divided by the time slot of the data transmission. Illustratively, the division is by 1 slot, i.e. each slot corresponds to one second data segment. For example, as shown in fig. 2, the second data packet is received through 5 time slots, and the second data packet is divided into 5 second data segments, that is, time slot N +1, time slot N +2, time slot N +3, and time slot N +4 correspond to one second data segment respectively. Illustratively, the division may also be made in 1/2 time slots. Also for example, the division may be made in 1/4 time slots. Illustratively, the division may also be made in 2 slots. In this embodiment, the second data packet may be divided according to actual needs, so as to reduce the data processing amount during checking while improving the retransmission efficiency.

In this embodiment, before the slave earphone determines the data segment that fails to be transmitted in the first data packet according to the first verification result and the second verification result of the second data packet, the slave earphone verifies the second data packet. The checking the second data packet may include checking the integrity of the received second data packet to obtain second check information. And checking the second data packet, which may further include splitting the second data packet, and checking each second data segment of the second data packet to obtain a second check code corresponding to each second data segment. The second parity result includes second parity information indicating whether the second data packet is complete and second parity code for each of the plurality of second data segments. Continuing with the example of fig. 2, the second data packet is divided into 5 second data segments according to the time slot, and each second data segment correspondingly obtains a second parity code. Based on the second check information, it may be determined whether the second data packet is complete, i.e. whether the second data packet failed to be transmitted. It may further be determined from the second check code which of the second data segments in the second data packet failed to be transmitted.

It will be appreciated that the second data packet may be checked in a cyclic redundancy check, CRC, check, e.g., CRC-32. The second data packet may also be checked in a parity check. The embodiment of the present application does not limit the checking method of the second data packet.

In specific implementation, as shown in fig. 2, after the electronic device sends the first data packet to the master earphone and before the time slot is not completed, that is, in the time slot T3 of the (N + 5) th time slot, the master earphone verifies the first data packet to obtain a first verification result, and synchronizes the first verification result to the slave earphone. And in the time period T5, the slave earphone checks the second data packet to obtain a second check result, and synchronizes the second check result to the master earphone. After the synchronization check result, the master earpiece transmits an acknowledgement packet (ACK) to the electronic device. And then the slave earphone determines whether the first data packet is complete or not according to the first check information and determines whether the second data packet is complete or not according to the second check information, the slave earphone compares the first check code of each first data segment of the first data packet with the second check code of the corresponding second data segment respectively under the condition that the first check information indicates that the first data packet is incomplete and the second check information indicates that the second data packet is complete, determines the first data segment corresponding to the first check code as the data segment failed to be transmitted in the first data packet under the condition that the first check code and the second check code are inconsistent, and sends the second data segment corresponding to the data segment failed to the master earphone.

After step 1200, step 1300b is executed to receive the second check result sent by the slave earphone, determine the data segment failed to be transmitted in the second data packet according to the first check result and the second check result, and send the first data segment corresponding to the data segment failed to be transmitted in the second data packet to the slave earphone.

In some embodiments, the first check result includes first check information indicating whether the first data packet is complete, and a first check code of each of the plurality of first data segments; the second parity result includes second parity information indicating whether the second data packet is complete and second parity code for each of the plurality of second data segments; the determining, according to the first check result and the second check result, a data segment in the second data packet that fails to be transmitted may further include: and under the condition that the first check information indicates that the first data packet is complete and the second check information indicates that the second data packet is not complete, determining the data segments which fail to be transmitted in the second data packet according to the first check code of each first data segment and the second check code of each second data segment.

In this embodiment, the first check result includes first check information indicating whether the first data packet is complete, and a first check code of each of the plurality of first data segments. Taking fig. 3 as an example, the first data packet is divided into 5 first data segments according to the time slot, and each first data segment corresponds to obtain a first check code. Based on the first check information, it may be determined whether the first data packet is complete, i.e. whether the first data packet fails to be transmitted. It may further be determined from the first check code which data segment of the first data packet failed to be transmitted.

The second parity result includes second parity information indicating whether the second data packet is complete and second parity code for each of the plurality of second data segments. Continuing with the example of fig. 3, the second data packet is divided into 5 second data segments according to the time slot, and each second data segment corresponds to a second parity code. Based on the second check information, it may be determined whether the second data packet is complete, i.e. whether the second data packet failed to be transmitted. It may further be determined from the second check code which data segment of the second data packet failed to be transmitted.

In specific implementation, as shown in fig. 3, after the electronic device sends the first data packet to the master earphone and before the time slot is not completed, that is, in the time slot T3 of the (N + 5) th time slot, the master earphone verifies the first data packet to obtain a first verification result, and synchronizes the first verification result to the slave earphone. And in the time period T5, the slave earphone checks the second data packet to obtain a second check result, and synchronizes the second check result to the master earphone. After the synchronization check result, the master earphone transmits an acknowledgement packet (ACK) to the electronic device. And then the master earphone determines whether the first data packet is complete or not according to the first check information and determines whether the second data packet is complete or not according to the second check information, the master earphone compares the first check code of each first data segment of the first data packet with the second check code of the corresponding second data segment respectively under the condition that the first check information indicates that the first data packet is complete and the second check information indicates that the second data packet is incomplete, the master earphone determines the second data segment corresponding to the second check code as the data segment failed to be transmitted in the second data packet under the condition that the first check code and the second check code are inconsistent, and sends the first data segment corresponding to the data segment failed to the slave earphone.

In some embodiments, after the first verification result is sent to the slave earphone so that the slave earphone determines the data segment which fails to be transmitted in the first data packet according to the first verification result and the second verification result of the second data packet, and receives the second data segment which is sent by the slave earphone and corresponds to the data segment which fails to be transmitted in the first data packet, the master earphone verifies the second data segment which is sent by the slave earphone and corresponds to the data segment which fails to be transmitted in the first data packet.

In specific implementation, before receiving a second data segment corresponding to the data segment which fails to be transmitted in the first data packet and sent from the earphone, the master earphone receives a second check result sent from the earphone, and determines the data segment which fails to be transmitted in the first data packet according to the first check result and the second check result. In this way, after receiving the second data segment corresponding to the data segment failed in transmission in the first data packet sent by the slave earphone, the master earphone may check the received second data segment corresponding to the data segment failed in transmission in the first data packet, so as to ensure the correctness of the retransmitted data segment.

In some embodiments, after the receiving the first data packet sent by the electronic device, the method may further include: step 2100-step 2300.

In step 2100, a first parameter corresponding to each of the plurality of first data segments is obtained, where the first parameter is used to measure a link quality of a first signal link, and the first signal link is a signal link between the main headset and the electronic device.

In this embodiment, the first signal link is a signal link between the primary earpiece and the electronic device. The success rate of receiving data from the primary earpiece may be affected by the link quality of the first signal link. And the quality of the link quality of the first signal link is related to the distance between the master earphone and the electronic device, e.g., the farther the master earphone is from the electronic device, the worse the link quality of the first signal link. The closer the primary earpiece is to the electronic device, the higher the link quality of the first signal link. For example, if the user wearing the main headset faces the electronic device, the link quality of the first signal link is better, and if the user wearing the main headset faces away from the electronic device, the link quality of the first signal link is worse. Based on this, in the process of receiving the first data packet, the link quality of the first signal link can be detected, so as to judge the data segment which is possibly failed to be transmitted in the first data packet according to the link quality of the first signal link.

The first parameter may be used to measure a link quality of the first signal link. Each of the plurality of first data segments corresponds to a first parameter, and the first parameter may reflect link quality of the first signal link in the process of acquiring the first data segment. Taking the example of dividing the data segment by the time slot, the first parameter may be a first parameter corresponding to the time slot in which the first data segment is transmitted.

It will be appreciated herein that the first parameter may be a signal-to-noise ratio of a signal received by the first signal link. The first parameter may also be a Received Signal Strength (RSSI) of a Signal Received by the first Signal link.

Step 2200, determining the first data segment corresponding to the first parameter as the data segment failed in transmission in the first data packet, if the parameter value of the first parameter is smaller than the first threshold value.

In this embodiment, the first threshold may measure whether the link quality of the first signal link is poor. When the parameter value of the first parameter is smaller than the first threshold, it is determined that the first data segment corresponding to the first parameter is the data segment of the first data packet, which has failed to be transmitted.

Step 2300, sending a first identifier corresponding to the data segment failed in transmission in the first data packet to the slave earphone, so that the slave earphone sends a second data segment corresponding to the data segment failed in transmission in the first data packet according to the first identifier.

In this embodiment, the first identifier is used to identify a data segment in the first data packet that failed in transmission. Illustratively, the first identifier may be a time slot corresponding to a data segment of the first data packet that failed to be transmitted.

In this embodiment, when the primary earpiece receives the first data packet through the first signal link, the link quality of the first signal link is combined, so that a data segment in the first data packet, in which transmission failure may occur, can be predicted, and the first data packet does not need to be checked, which can reduce the processing computation amount and further reduce the delay.

It should be noted that, in this embodiment, before the first data packet is verified to obtain the first verification result, the data segment that fails to be transmitted in the first data packet may be determined and retransmitted in combination with the link quality of the first signal link, and then, the integrity and the correctness of the first data packet are verified again in a verification manner, so as to ensure the correctness of data transmission.

As shown in fig. 4, the present embodiment also provides a data transmission method applied to a slave headset, which may include the following steps, which are described in detail below.

Step 3100, in case of receiving a second data packet corresponding to the first data packet, verifying the second data packet to obtain a second verification result.

In one embodiment, the second data packet is divided into a plurality of second data segments according to the setting parameters. Wherein the setting parameter is determined according to the time slot of the transmission data. That is, the division may be made by time slots of data transmission. Illustratively, the division is by 1 slot, i.e. each slot corresponds to one second data segment. For example, as shown in fig. 2, the second data packet is received through 5 time slots, and the second data packet is divided into 5 second data segments, that is, time slot N +1, time slot N +2, time slot N +3, and time slot N +4 correspond to one second data segment respectively. Illustratively, the division may also be made in 1/2 time slots. Also for example, the division may be made in 1/4 time slots. Illustratively, the division may also be made in 2 slots. In this embodiment, the second data packet may be divided according to actual needs, so as to improve retransmission efficiency and reduce data processing amount during checking.

In this embodiment, the verifying the second data packet may include verifying the integrity of the received second data packet to obtain the second verification information. And checking the second data packet, which may further include splitting the second data packet, and checking each second data segment of the second data packet to obtain a second check code corresponding to each second data segment. The second parity result includes second parity information indicating whether the second data packet is complete and second parity code for each of the plurality of second data segments. Continuing with the example of fig. 2, the second data packet is divided into 5 second data segments according to the time slot, and each second data segment corresponds to a second parity code. Based on the second check information, it may be determined whether the second data packet is complete, i.e. whether the second data packet failed to be transmitted. It may further be determined from the second check code which data segment of the second data packet failed to be transmitted.

It will be appreciated that the second packet may be checked in a CRC check, for example CRC-32. The second data packet may also be checked in parity. The embodiment of the present application does not limit the checking method of the second data packet.

After step 3100, execute step 3200a, receive a first check result sent by a master earphone, determine a data segment that fails to be transmitted in the first data packet according to the first check result and the second check result, and send a second data segment corresponding to the data segment that fails to be transmitted in the first data packet to the master earphone.

In this embodiment, the first check result includes first check information indicating whether the first data packet is complete, and a first check code of each of the plurality of first data segments. Continuing with fig. 2 as an example, the first data packet is divided into 5 first data segments according to the time slot, and each first data segment corresponds to obtain a first check code. Based on the first check information, it may be determined whether the first data packet is complete, i.e. whether the first data packet fails to be transmitted. It may further be determined from the first check code which of the first data segments in the first data packet failed to be transmitted.

In some embodiments, the first check result includes first check information indicating whether the first data packet is complete, and a first check code of each of the plurality of first data segments; the second parity result includes second parity information indicating whether the second data packet is complete and second parity code for each of the plurality of second data segments; the determining, according to the first check result and the second check result, a data segment in the first data packet that fails to be transmitted may further include: and under the condition that the first check information indicates that the first data packet is incomplete and the second check information indicates that the second data packet is complete, determining the data segment which fails to be transmitted in the first data packet according to the first check code of each first data segment and the second check code of each second data segment.

In specific implementation, with reference to fig. 2, after the electronic device sends the first data packet to the master earphone and before the time slot is not completed, that is, in the time slot T3 of the (N + 5) th time slot, the master earphone verifies the first data packet to obtain a first verification result, and synchronizes the first verification result to the slave earphone. And in the time period T5, the slave earphone checks the second data packet to obtain a second check result, and synchronizes the second check result to the master earphone. After the synchronization check result, the master earpiece transmits an acknowledgement packet (ACK) to the electronic device. And then the slave earphone determines whether the first data packet is complete or not according to the first check information and determines whether the second data packet is complete or not according to the second check information, the slave earphone compares the first check code of each first data segment of the first data packet with the second check code of the corresponding second data segment respectively under the condition that the first check information indicates that the first data packet is incomplete and the second check information indicates that the second data packet is complete, determines the first data segment corresponding to the first check code as the data segment failed to be transmitted in the first data packet under the condition that the first check code and the second check code are inconsistent, and sends the second data segment corresponding to the first data segment failed to the master earphone.

After step 3100, step 3200b is executed to send the second check result to the master earphone, so that the master earphone determines the data segment in the second data packet that fails to be transmitted according to the second check result and the first check result, and receives the first data segment sent by the master earphone and corresponding to the data segment in the second data packet that fails to be transmitted.

In specific implementation, as shown in fig. 3, after the electronic device sends the first data packet to the master earphone and before the time slot is not completed, that is, in the time slot T3 of the (N + 5) th time slot, the master earphone verifies the first data packet to obtain a first verification result, and synchronizes the first verification result to the slave earphone. And in the time period T5, the slave earphone checks the second data packet to obtain a second check result, and synchronizes the second check result to the master earphone. After the synchronization check result, the master earpiece transmits an acknowledgement packet (ACK) to the electronic device. And then the master earphone determines whether the first data packet is complete or not according to the first check information and determines whether the second data packet is complete or not according to the second check information, the master earphone compares the first check code of each first data segment of the first data packet with the second check code of the corresponding second data segment respectively under the condition that the first check information indicates that the first data packet is complete and the second check information indicates that the second data packet is incomplete, the master earphone determines the second data segment corresponding to the second check code as the data segment failed to be transmitted in the second data packet under the condition that the first check code and the second check code are inconsistent, and sends the first data segment corresponding to the data segment failed to the slave earphone.

In this embodiment of the application, when a second data packet corresponding to a first data packet is received from a headset, the second data packet is verified to obtain a second verification result, and when a first verification result of the first data packet sent by a master headset is received, a data segment failed in transmission in the first data packet is determined according to the first verification result and the second verification result, and a second data segment corresponding to the data segment failed in transmission is sent to the master headset. And after the slave earphone checks the second data packet to obtain a second check result, the slave earphone may also send the second check result to the master earphone, so that the master earphone determines the data segment failed in transmission in the second data packet according to the second check result and the first check result, and receives the first data segment sent by the master earphone and corresponding to the data segment failed in transmission in the second data packet. Therefore, the master earphone and the slave earphone can perform mutual compensation based on the stored effective data, the data compensation effect of the master earphone and the slave earphone can be improved, a complete data packet does not need to be retransmitted, the transmission quantity of data can be reduced, the transmission time is saved, and the sound blocking is prevented. In addition, data compensation is performed by using the transmission time slot, so that the utilization rate of the time slot can be improved, and the improvement of the communication bandwidth and the reduction of the communication delay are facilitated.

In some embodiments, after receiving the first data segment corresponding to the data segment failed to be transmitted in the second data packet sent by the master earphone, the slave earphone checks the first data segment corresponding to the data segment failed to be transmitted in the second data packet sent by the master earphone.

In specific implementation, before receiving a first data segment corresponding to a data segment which fails to be transmitted in a second data packet and sent by a master earphone, a first check result sent by the master earphone is received by the slave earphone, and the data segment which fails to be transmitted in the second data packet is determined according to the first check result and a second check result. In this way, after receiving the first data segment corresponding to the data segment failed in transmission in the second data packet sent by the master earphone, the slave earphone can verify the received first data segment corresponding to the second data segment failed in transmission in the second data packet, so as to ensure the correctness of the retransmitted data segment.

In some embodiments, before the performing the verification on the second data packet to obtain the second verification result, the method may further include: step 4100-step 4300.

Step 4100, acquiring a second parameter corresponding to each of the second data segments, where the second parameter is used to measure link quality of a second signal link, and the second signal link is a listening link of the slave earphone.

In this embodiment, the second signal link is a listening link from the headset. The success rate of receiving data from the headset is affected by the quality of the link of the second signal link. And the quality of the link quality of the second signal link is related to the distance from the headset to the electronic device, e.g. the further from the headset to the electronic device, the worse the link quality of the second signal link. The closer the headset is to the electronic device, the higher the link quality of the second signal link. Also for example, the link quality of the second signal link is better when the user wearing the slave ear piece faces the electronic device, and the link quality of the second signal link is worse when the user wearing the slave ear piece faces away from the electronic device. Based on this, in the process of receiving the second data packet, the link quality of the second signal link may be detected, so as to judge that the second data segment with transmission failure may occur in the second data packet according to the link quality of the second signal link.

The second parameter may be used to measure a link quality of the second signal link. The second parameter corresponding to the second data segment may reflect the link quality of the second signal link in the process of acquiring the second data segment. Taking the division of the data segment according to the time slot as an example, the second parameter corresponding to the second data segment may be a second parameter corresponding to the time slot for transmitting the second data segment.

It will be appreciated herein that the second parameter may be a signal-to-noise ratio of the signal received by the second signal link. The first parameter may also be an RSSI value of a signal received by the second signal link.

Step 4200, if the parameter value of the second parameter is smaller than a second threshold, determining a second data segment corresponding to the second parameter as a data segment that fails to be transmitted in the second data packet.

In this embodiment, the second threshold may measure whether the link quality of the second signal link is poor. And when the parameter value of the second parameter is smaller than the second threshold, determining that the second data segment corresponding to the second parameter is the data segment which fails to be transmitted in the second data packet.

Step 4300, sending a second identifier corresponding to the data segment that fails to be transmitted in the second data packet to the master earphone, so that the master earphone sends the first data segment corresponding to the data segment that fails to be transmitted in the second data packet according to the second identifier.

In this embodiment, the second identifier is used to identify the data segment in the second data packet that failed to be transmitted. Illustratively, the second identifier may be a time slot corresponding to a data segment of the second data packet that failed to be transmitted.

In this embodiment, when the second data packet is received from the earphone through the second signal link, in combination with the link quality of the second signal link, a data segment in which transmission failure may occur in the second data packet may be predicted, and the second data packet does not need to be checked, so that the processing operation amount may be reduced, and the delay may be further reduced.

It should be noted that, in this embodiment, before the second data packet is verified to obtain the second verification result, the link quality of the second signal link may be combined to determine the data segment that fails to be transmitted in the second data packet, and retransmit the data segment that fails to be transmitted in the first data packet, and then, the integrity and the correctness of the second data packet are verified again by using a verification method, so as to ensure the correctness of data transmission.
