Due to the wide application of wireless communication technology, wireless products and services become a part of life of people, and particularly, wireless earphones centering on mobile phones or smart phones bring great convenience to life of people. However, as the demand for communication distance, communication quality, or communication reliability increases, the deficiencies of the wireless communication technology designed with low cost and low power consumption as the target are more and more evident in terms of communication distance and reliability.

Wireless headsets typically communicate with telephony devices such as mobile phones or smart phones using the bluetooth messaging protocol (HFP). The Connection-Oriented Extended Synchronous link (eSCO link) protocol adopted by the bluetooth call transmission protocol mainly adopts a modulation technique without error correction coding and adopts a limited number of automatic retransmission mechanisms based on Cyclic Redundancy Check (CRC) to realize the call. However, in more and more complex interference and fading environments, especially with occluded long distance transmissions, the quality or reliability of communication between devices that use a limited number of retransmission mechanisms to achieve communication is poor. The wireless earphone supporting the double-ear call in a forwarding mode has more limited retransmission times with telephone equipment such as a mobile phone or a smart phone, and the communication quality or the communication reliability is poorer.

Detailed Description

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

Fig. 1 is a schematic structural diagram of a voice call system according to an embodiment of the present invention. As shown in fig. 1, the voice call system 100 includes: a telephone device 110, and a wireless headset 120. The wireless headset 120 includes a master headset 121 and a slave headset 122.

The telephone device 110 may be a mobile phone, a smart phone, a tablet computer, a cordless phone, or a wired phone.

In a preferred embodiment, the master earphone 121 and the slave earphone 122 of the wireless earphone 120 are each composed of a bluetooth transceiver module, a processor module, a voice output module and a voice input module. The Bluetooth wireless transceiver module is used for Bluetooth wireless communication and voice data transceiving; the processor module is used for performing Bluetooth protocol and processing voice data, such as voice data coding and decoding, voice data packet loss processing or packet error processing and the like; the voice output module is used for playing voice transmitted by the telephone equipment. The voice input module, namely a microphone, is used for collecting the local call voice data.

Specifically, the main headset 121 in the wireless headset 120 establishes a wireless connection with the telephone device 110, thereby implementing a two-way call based on the first communication link; the master earphone 121 and the slave earphone 122 share link information corresponding to the wireless connection between the master earphone 121 and the telephone device 110, so that the slave earphone 122 can receive the first voice data transmitted to the master earphone 121 from the telephone device 110 based on the link information shared by the master earphone 121; in this way, it is achieved that, at the same time, the master earphone 121 and the slave earphone 122 simultaneously acquire the first voice data sent by the telephone equipment 110; if one of the master earphone 121 and the slave earphone 122 does not correctly acquire the first voice data, the incorrectly acquired party receives the other party and forwards the first voice data. In addition, the master earphone 121 and/or the slave earphone 122 are also used for transmitting the collected second voice data to the telephone apparatus 110 to implement a two-way voice call.

Fig. 2 is a flowchart illustrating a wireless headset communication method according to an embodiment of the present invention. The wireless headset-less communication method is applied to a wireless headset in a voice call system shown in fig. 1, wherein a master headset and a slave headset in the wireless headset perform data interaction through wired or wireless connection.

In the embodiment of the invention, the wireless earphone at least comprises two earphones, and in the invention, the earphone which directly establishes wireless connection with the telephone equipment in the wireless earphone is determined as a main earphone; and determining the earphone except the master earphone in the wireless earphones as the slave earphone.

It should be further explained here that directly establishing wireless connection with the telephone device means that only the earphone and the telephone device participate in completing the establishment of wireless connection in the process of establishing wireless connection between the earphone and the telephone device, so as to realize mutual transceiving of voice data between the main earphone and the telephone device; the process of realizing mutual voice data receiving and sending between the earphone and the telephone equipment comprises the following steps: first, the slave headset needs to acquire link information between the master headset and the telephone device from the master headset that has established wireless connection with the mobile device, so that the slave headset acquires voice data sent by the telephone device based on the acquired link information.

Referring to fig. 1, the method includes the following steps:

and 201, establishing wireless connection between the main earphone and the telephone equipment, and realizing two-way conversation based on the first communication link.

The master earpiece also shares link information with the slave earpiece corresponding to the wireless connection between itself and the telephony device 202.

And 203, receiving the first voice data sent to the main earphone by the telephone equipment from the auxiliary earphone based on the link information shared by the main earphone.

And 204, if one of the master earphone and the slave earphone does not acquire the first voice data correctly, the incorrectly acquired party receives the other party and forwards the first voice data.

It should be noted here that, since the master earphone and the slave earphone of the wireless earphone share the link information between the master earphone and the telephone device, the telephone device can simultaneously transmit the first voice data to the master earphone and the slave earphone, and when the master earphone receives the first voice data, the slave earphone in a different spatial position from the master earphone can also simultaneously receive the first voice data, so that even if the wireless connection link between one earphone of the wireless earphones and the telephone device is interfered or blocked and cannot receive the first voice data, the wireless earphone can also receive the first voice data through the other earphone, and thus, when the number of times of retransmitting the first voice data by the wireless earphone and the telephone device is limited, the communication quality and the communication reliability between the wireless earphone and the telephone device are improved.

In addition, in the embodiment of the invention, when any one of the master earphone and the slave earphone does not correctly receive the first voice data, the correctly received party forwards the first voice data to the other party, so that the first voice data can be correctly received by all earphones in the wireless earphone under the conditions of more and more complex interference and fading environments, particularly under the condition of shielded long-distance transmission, and under the condition of not increasing the retransmission times of the wireless earphone and the telephone equipment, and the communication quality of the double-ear wireless earphone and the telephone equipment is further improved to a certain degree.

The following specifically explains the implementation process of the technical scheme provided by the invention with respect to the above steps.

Further, in the wireless headset provided by the present invention, the master headset and the slave headset perform data interaction through wired or wireless connection, that is, when the master headset and the slave headset still share link information corresponding to the wireless connection between the master headset and the telephone device in step 202, the master headset may share the link information corresponding to the wireless connection between the master headset and the telephone device to the slave headset through a wired transmission manner; alternatively, the master earphone may share link information corresponding to the wireless connection between the master earphone and the telephone device to the slave earphone by a wireless method such as bluetooth or infrared.

In a possible implementation, the master earphone establishes a wireless connection with the slave earphone based on link information corresponding to the wireless connection between the master earphone and the telephone device, and performs bidirectional communication with the slave earphone based on the second communication link, so that the master earphone shares link information corresponding to the wireless connection between the master earphone and the telephone device with the slave earphone in a wireless manner.

It should be noted here that the first communication link between the master earphone and the telephone device and the second communication link between the master earphone and the slave earphone are both obtained from link information corresponding to the wireless connection between the master earphone and the telephone device, that is, the first communication link and the second communication link have the same communication link parameters.

Further, the first communication link and the second communication link have the same communication link parameters, and therefore, the slot structures corresponding to the communication link and the second communication link are also the same. Preferably, the time slot structures of the first communication link and the second communication link are: the link interval comprises voice transceiving time slots at least used for transceiving voice data packets with the telephone equipment, voice retransmission time slots at least used for retransmitting the voice data packets with the telephone equipment, and extended time slots at least used for forwarding the voice data packets between the master earphone and the slave earphone.

On the premise of ensuring the conversation quality between the wireless earphone and the telephone equipment, the link resources occupied by the first communication link and the second communication link are fully utilized, so that the link resources are saved to a certain extent, the voice transceiving time slot in the time slot structure is not used for transceiving voice data packets with the telephone equipment, and/or the voice retransmission time slot is not used for retransmitting the voice data packets with the telephone equipment, and/or the expansion time slot is not used for retransmitting the voice data packets between the master earphone and the slave earphone, and the voice transceiving time slot, the voice retransmission time slot and/or the expansion time slot can also be used for realizing other purposes. For example, in a link interval, if the main headset and the telephone device do not need to retransmit the voice data packet or only need to occupy part of the voice retransmission timeslot for retransmitting the voice data packet, the voice retransmission timeslot that is not used for retransmitting the voice data packet may be used for forwarding the voice data packet between the main headset and the main headset.

In order to enable an opposite party to know the condition of receiving voice data sent by the opposite party in the process of sending and receiving the voice data between the wireless earphone and the telephone equipment, after the voice data sent by the opposite party is received, the receiving condition of the wireless earphone needs to be fed back to the opposite party, and based on the condition, the process of sending and receiving the voice data between the wireless earphone and the telephone equipment is carried out by combining the time slot structures corresponding to the first communication link and the second communication link, which is specifically as follows: the master earphone and the slave earphone receive first voice data from the telephone equipment in a voice transceiving time slot and a voice retransmission time slot, and reply a confirmation message whether the first voice data is correctly received or not to the telephone equipment in the voice transceiving time slot and the voice retransmission time slot; and the master earphone or the slave earphone sends second voice data to the telephone equipment in the voice transceiving time slot and the voice retransmission time slot, and receives a confirmation message whether the second voice data is correctly received or not from the telephone equipment in the voice transceiving time slot and the voice retransmission time slot after the master earphone or the slave earphone sends the second voice data to the telephone equipment.

Further, the master earphone and the slave earphone carry out first voice data forwarding between the master earphone and the slave earphone in an extended time slot; and after the other party does not correctly receive the forwarded first voice data, retransmitting the first voice data which is not correctly received by the other party. Specifically, the master earphone and the slave earphone forward the first voice data between the master earphone and the slave earphone in the extended time slot, and reply to the other party in the extended time slot whether the confirmation message of the first voice data is correctly received, if the confirmation message of the first voice data which is not correctly received is replied by one party, the other party retransmits the first voice data.

In the present invention, optionally, another time slot is further included in one link interval, and the other time slot is used for maintaining the wireless connection between the main earphone and the telephone device and maintaining the wireless connection between the main earphone and the main earphone at least when the main earphone and the main earphone do not need to retransmit voice data with the telephone device and the main earphone do not need to retransmit voice data.

The other time slots in one link interval in the invention can be used for other purposes when the other time slots are not used for retransmitting voice data by different telephone equipment, are not used for master and slave earphones, do not need to forward the voice data, are not used for maintaining the wireless connection between the master earphone and the telephone equipment, and are not used for maintaining the wireless connection between the master earphone and the slave earphone.

In order to avoid as much as possible that two adjacent time slots in one link interval are both used for transmitting data, in the present invention, it is optional to have 1 or more idle time slots between two adjacent time slots in one link interval for transmitting data. It should be further noted that, by spacing 1 or more idle time slots between two adjacent time slots for transmitting data, the implementation difficulty can be reduced.

Further, in the above feasible implementation manner, the wireless connections established between the master earphone and the telephone device and between the master earphone and the slave earphone may be wireless connections established based on infrared rays, and may also be wireless connections established based on ZigBee (ZigBee protocol), and the present invention preferably establishes wireless connections based on a bluetooth wireless communication protocol. If the wireless connection is established between the master earphone and the telephone equipment and between the master earphone and the slave earphone based on the Bluetooth wireless communication protocol, the first communication link and the second communication link both comprise an eSCO bottom link and an HFP upper link; the link information includes at least: a bluetooth clock, an encryption key, an adaptive frequency hopping channel map, and a master bluetooth address for the wireless connection between the master earpiece and the telephone device.

Please refer to fig. 3, which is a schematic structural diagram of a voice call system according to the present invention. The telephone apparatus 30 and the wireless headset 31 are included in the voice call system, and the wireless headset 31 includes a master headset 310 and a slave headset 320. In the voice call system shown in fig. 3, the wireless connection between the primary headset 310 and the telephone device 30 is established through a bluetooth wireless communication protocol, that is, the primary headset 310 and the telephone device 30 implement a bidirectional call link through an HFP upper link and an eSCO lower link, wherein the telephone device 30 serves as a bluetooth Master device (primary device) of the corresponding bluetooth wireless connection between the primary headset 310 and the telephone device 30, and the primary headset 310 serves as a bluetooth Slave device (secondary device). The wireless connection between the Master earphone 310 and the Slave earphone 320 is also established through a bluetooth wireless communication protocol, that is, the Master earphone 310 and the Slave earphone 320 implement a bidirectional communication link through an HFP upper layer link and an eSCO lower layer link, wherein the Master earphone 310 serves as a bluetooth Master device (Master device) of the corresponding bluetooth wireless connection between the Master earphone 310 and the Slave earphone 320, and the Slave earphone 320 serves as a bluetooth Slave device (Slave device).

In the voice communication system described in conjunction with fig. 3, the master earphone 310 establishes a wireless connection with the slave earphone 320 based on link information corresponding to the wireless connection between the master earphone 310 and the telephone device 30, and implements bidirectional communication with the slave earphone 320 based on a second communication link, specifically: the master headset 310 establishes a bluetooth wireless connection with the slave headset 320 using Link Key (Link Key), Adaptive Frequency-Hopping (AFH) Channel Mapping (Channel Mapping), bluetooth clock, and Link information such as a bluetooth address of the telephone device 30, which are identical to those of the bluetooth wireless connection between the master headset 310 and the telephone device 30, so that an eSCO lower Link and an HFP upper Link having exactly the same parameters as those of the master headset 310 and the telephone device 30 are established between the master headset 310 and the slave headset 320.

Regarding step 204, the party that does not receive voice data correctly may be the master earphone or the slave earphone, and the implementation of step 204 is specifically described below for these two cases.

In a specific scenario, if the party that does not correctly acquire the first voice data is the slave headset, step 204 specifically includes: the master earphone forwards the first voice data to the slave earphone; then, the slave earphone receives the first voice data forwarded by the master earphone, and after the slave earphone correctly receives the first voice data, the slave earphone sends acknowledgement information to the master earphone to inform the master earphone that the master earphone correctly receives the first voice data, so that the master earphone receives the acknowledgement information. Further, after the master earphone receives the acknowledgement message, the master earphone ends the transmission of the first voice data with the slave earphone. It should be further added that, if the first voice data is forwarded to the slave earphone by the master earphone, the slave earphone still does not correctly receive the first voice data, at this time, the slave earphone sends a forwarding request message requesting for forwarding the first voice data to the master earphone, and the master earphone forwards the first voice data to the slave earphone after receiving the forwarding request message fed back by the slave earphone.

In another specific scenario, if the party that does not correctly acquire the first voice data is the primary earphone, step 204 specifically includes: the master earphone sends forwarding request information to the slave earphone, so that the slave earphone sends first voice data to the master earphone after receiving the forwarding request information; the master earphone receives first voice data sent by the slave earphone; and after the master earphone correctly receives the first voice data, the master earphone sends confirmation response information indicating that the first voice data is correctly received to the slave earphone, so that the slave earphone is indicated to finish the transmission of the first voice data with the master earphone. It should be further added that, if the first voice data is forwarded from the slave earphone to the master earphone, the master earphone still does not correctly receive the first voice data, at this time, the master earphone sends a forwarding request message to the slave earphone again, so that the slave earphone sends the first voice data again, the master earphone receives the first voice data sent from the slave earphone, and feeds back an acknowledgement response message to the slave earphone to indicate that the slave earphone finishes transmitting the first voice data with respect to the first voice data with the master earphone.

Further, in a case where the master earphone and the slave earphone receive the first voice data sent by the telephone device, it is to be further added that, if the master earphone does not correctly receive the first voice data, the master earphone sends a forwarding request message to the slave earphone, and after the slave earphone receives the forwarding request message, the slave earphone determines that neither the master earphone nor the slave earphone correctly receives the first voice data based on the situation that the master earphone receives the first voice data and the situation that the slave earphone receives the forwarding request message, and therefore, the slave earphone directly sends an acknowledgement message to the master earphone, so that the master earphone determines that neither the master earphone nor the slave earphone correctly receives the first voice data based on the situation that the master earphone receives the first voice data and the acknowledgement message. Further, in order to ensure that the wireless headset and the telephone device can smoothly perform two-way voice communication under the condition, the master headset and the slave headset respectively perform packet loss and/or packet error processing based on the currently received voice data of the master headset and the slave headset to recover the first voice data under the condition that the master headset and the slave headset determine that both parties do not correctly receive the first voice data. Alternatively, the master earphone may transmit notification information indicating that the master earphone has correctly received the first voice data to the slave earphone, so that the slave earphone may determine that both the master earphone and the slave earphone have correctly received the first voice data based on the fact that the slave earphone has received the first voice data and the notification information, and may transmit acknowledgement information directly to the master earphone, so that the master earphone may determine that both have correctly received the first voice data based on the fact that the master earphone has received the first voice data and the acknowledgement information. Specifically, the form of the notification information sent from the master earphone to the slave earphone may be the first voice data, or may be confirmation information indicating that the first voice data is correctly received.

In order to realize the two-way voice call between the wireless earphone and the telephone equipment, after the wireless earphone acquires the first voice data sent by the telephone equipment, the wireless earphone needs to send the voice reply of the user to the telephone equipment.

Specifically, after the master earphone and the slave earphone in the wireless earphone receive the first voice data, the voice output module in the master earphone and the slave earphone plays the first voice data, so that a user wearing the wireless earphone can hear the first voice data and make a voice reply, that is, the user inputs the second voice data, and thus the voice input module of one of the master earphone and the slave earphone collects the second voice data and sends the second voice data to the telephone equipment, so as to realize two-way voice communication.

On the basis of the implementation method provided by the invention, the stability of wireless connection between the wireless earphone and the telephone equipment is required to be ensured in the process of sending the second voice data to the telephone equipment by the wireless earphone, so as to further ensure the reliability of voice communication between the wireless earphone and the telephone equipment. Under the guidance of this idea, an embodiment of the present invention further provides a feasible implementation manner, where before sending the second voice data to the telephone device, the method specifically further includes: the method comprises the steps that a main earphone of the wireless earphone respectively obtains first link quality between the main earphone and telephone equipment and second link quality between a slave earphone and the telephone equipment; then, the main earphone determines to execute acquisition of second voice data according to the first link quality and the second link quality, and sends the second voice data to the earphone of the telephone equipment. The determining, by the master earphone, to acquire the second voice data according to the first link quality and the second link quality includes: the master earphone compares the first link quality with the second link quality, so that an earphone with higher link quality is determined as a target earphone for acquiring second voice data; for example, after the comparison, if it is determined that the first link quality is higher than the second link quality, it is determined that the main earphone acquires the second voice data, and the main earphone is used to transmit the second voice data; or, after the comparison, if it is determined that the first link quality is lower than the second link quality, it is determined that the slave earphone acquires the second voice data and transmits the second voice data using the slave earphone, in this case, the master earphone needs to send an instruction to the slave earphone to transmit the second voice data, and then, the slave earphone performs an operation of acquiring and transmitting the second voice data. Optionally, in this embodiment, the quality of the wireless link is indicated by a Received Signal Strength Indicator (RSSI).

In an application scenario, a wireless connection between a wireless headset and a telephone device is affected by external factors, link quality changes within a certain time, and if the two link qualities are only compared to determine the headset performing second voice data transmission, the headset performing the second voice data transmission is frequently switched during a voice call, so that a voice call effect is affected, based on which, in order to avoid that the headset performing the second voice data transmission is frequently switched during the second voice data transmission process of the wireless headset, the invention provides a feasible implementation method for determining to perform acquisition of the second voice data for a main headset according to the first link quality and the second link quality, and sending the second voice data to the headset of the telephone device, and the idea of the method is that: and setting a first threshold value of link quality and a second threshold value of link quality, wherein the first threshold value of link quality is smaller than the second threshold value of link quality, if one of the first link quality and the second link quality is smaller than or equal to the first threshold value of link quality, and the other link quality is larger than or equal to the second threshold value of link quality, and transmitting second voice data by an earphone of which the link quality is larger than or equal to the second threshold value of link quality. Specifically, if the first link quality does not reach a first threshold value of the link quality and the second link quality reaches or exceeds a second threshold value of the link quality, determining to acquire second voice data from the earphone and sending the second voice data to the telephone equipment; or if the second link quality does not reach the link quality first threshold value and the first link quality reaches or exceeds the link quality second threshold value, determining that the main earphone acquires second voice data and sending the second voice data to the telephone equipment; wherein the first threshold value of the link quality is smaller than the second threshold value of the link quality.

Specifically, assume that in the above specific application scenario, the first threshold of the link quality is-80 dBm, and the second threshold of the link quality is-70 dBm. If the earphone which currently executes the second voice data transmission is a main earphone, if the link quality between the main earphone and the telephone equipment is lower than-80 dBm and the link quality between the slave earphone and the telephone equipment is higher than-70 dBm, the main earphone is switched to the slave earphone to send the second voice data to the telephone equipment through negotiation between the main earphone and the slave earphone; and if the link quality between the slave earphone and the telephone equipment is lower than-80 dBm and the link quality between the master earphone and the telephone equipment is higher than-70 dBm, the master earphone keeps sending the second voice data to the telephone equipment. Or, if the earphone currently executing the second voice data transmission is the slave earphone, if the link quality between the master earphone and the telephone equipment is lower than-80 dBm and the link quality between the slave earphone and the telephone equipment is higher than-70 dBm, the master earphone and the slave earphone negotiate to switch the slave earphone to the master earphone and send the second voice data to the telephone equipment; if the link quality between the slave earphone and the telephone equipment is lower than-80 dBm and the link quality between the master earphone and the telephone equipment is higher than-70 dBm, the voice data sent by the slave earphone to the telephone equipment is kept.

In another application scenario, in order to balance the remaining power of the master and slave earphones, the service life of the master and slave earphones is provided to a certain extent, the invention provides that when the earphone for second voice data transmission is determined based on the link quality, the earphone with a large remaining power can be further determined to perform the second voice data transmission according to the remaining power of the master and slave earphones, so that the remaining power of the master and slave earphones is balanced to a certain extent. The method specifically comprises the following steps: if the first link quality and the second link quality both reach or exceed a third threshold value of the link quality, the master earphone respectively acquires a first residual electric quantity of the master earphone and a second residual electric quantity of the slave earphone; therefore, the remaining power is further compared, specifically, if the first remaining power and the second remaining power are both greater than the power first threshold value, and the difference value obtained by subtracting the second remaining power from the first remaining power is greater than the power second threshold value, it is determined that the main earphone acquires the second voice data, and the second voice data is sent to the telephone equipment; or if the first residual electric quantity and the second residual electric quantity are both larger than the electric quantity first threshold value, and the difference value of the second residual electric quantity minus the first residual electric quantity is larger than the electric quantity second threshold value, determining to acquire second voice data from the earphone, and sending the second voice data to the telephone equipment.

Specifically, in the above specific application scenario, it is assumed that the third threshold of the link quality is-70 dBm, the rated power of the wireless headset is 15% of the first threshold of the power, the second threshold of the power is 20% of the remaining power of the higher one of the first power and the second power, and the link qualities corresponding to the master headset and the slave headset are both greater than-70 dBm. If the earphone currently executing the second voice data transmission is a main earphone, if the residual electric quantity of the main earphone and the slave earphone is higher than 15% of the rated electric quantity of the wireless earphone, and the difference of subtracting the residual electric quantity of the main earphone from the residual electric quantity of the earphone is more than 20% of the residual electric quantity of the slave earphone, the main earphone and the slave earphone negotiate to be switched to the slave earphone by the main earphone to send the second voice data to the telephone equipment; and if the residual electric quantity of the main earphone and the slave earphone is higher than 15% of the rated electric quantity of the wireless earphone, and the difference of the residual electric quantity of the main earphone minus the residual electric quantity of the slave earphone is larger than 20% of the residual electric quantity of the main earphone, the main earphone keeps sending second voice data to the telephone equipment. Or, if the earphone currently executing the second voice data transmission is the slave earphone, if the remaining power of the master earphone and the slave earphone is higher than 15% of the rated power of the wireless earphone, and the difference between the remaining power of the master earphone and the remaining power of the slave earphone is greater than 20% of the remaining power of the master earphone, the master earphone and the slave earphone negotiate to switch the slave earphone to the master earphone and send the second voice data to the telephone equipment; if the residual capacity of the master earphone and the slave earphone is higher than 15% of the rated capacity of the wireless earphone, and the difference of subtracting the residual capacity of the master earphone from the residual capacity of the earphones is larger than 20% of the residual capacity of the slave earphone, the slave earphone keeps sending the second voice data to the telephone equipment.

It should be noted that the decision maker performing the step of determining the headset to perform the step of collecting the second voice data and transmitting the second voice data to the telephone device based on the link quality and/or the remaining power may be the master headset or the slave headset. The implementation principle of the earphone which determines to execute the collection of the second voice data and send the second voice data to the telephone equipment is the same as that of the earphone which determines to execute the collection of the second voice data and sends the second voice data to the telephone equipment and the earphone which determines to send the second voice data to the telephone equipment and takes the auxiliary earphone as the decision maker refers to the specific implementation mode which takes the main earphone as the decision maker, and the specific implementation mode which takes the auxiliary earphone as the decision maker is not described again.

The following describes a wireless headset communication method provided by the present invention with reference to a specific application scenario. In the specific application scenario, the telephone device is a smart phone, and the main device of the wireless connection between the main earphone and the smart phone is the smart phone.

Before the wireless earphone and the smart phone carry out bidirectional voice call, the wireless earphone is firstly in communication connection with the smart phone, namely, firstly, a main earphone of the wireless earphone establishes a wireless connection link (eSCO link) with the smart phone based on a Bluetooth wireless communication protocol, and realizes the bidirectional call function between the main earphone and the smart phone through an HFP protocol and the established eSCO link; then, the master earphone simulates the smart phone, and establishes wireless connection with the slave earphone by using link information of the smart phone, such as a Bluetooth address, a Bluetooth clock, an encryption key, a self-adaptive frequency hopping channel mapping chart and the like.

Please refer to fig. 4, which is a schematic diagram of an eSCO link timeslot structure established between a main headset and a smart phone according to the present invention. As shown in fig. 4, the one interval TeSCO of the eSCO link includes 12 slots (0.625 ms per slot), i.e., the one interval TeSCO of the eSCO link is 7.5ms and the phase DeSCO of the eSCO link is 0. In 12 time slots in the TeSCO interval, T0 and T1 are voice transceiving time slots between the main earphone and the smart phone; t2, T3, T4, and T5 are voice retransmission time slots between the main headset and the smartphone, that is, the retransmission window WeSCO is 4 time slots, that is, the retransmission window WeSCO is 2.5 ms; t6 and T7, T8 and T9 are the extended time slots for forwarding between the master and slave earphones; among them, T0, T2, T4, T7, and T9 are reception slots for the primary headset, and T1, T3, T5, T6, and T8 are transmission slots for the primary headset. T10 and T11 are other time slots for maintaining the bluetooth wireless connection and other information transmission between the master and slave earphones and the smart phone, and maintaining the bluetooth wireless connection and other information transmission between the master and slave earphones when the master earphone and the smart phone do not need to retransmit voice data, and the master and slave earphones do not need to retransmit voice data.

The eSCO link established between the master earphone and the slave earphone has the same parameters as the eSCO link established between the master earphone and the smart phone. That is, the eSCO link interval TeSCO is 12 slots, the retransmission window WeSCO is 4 slots, and DeSCO is 0. In addition, because the bluetooth clock and the channel mapping chart adopted between the master earphone and the slave earphone are completely the same as the bluetooth clock and the channel mapping chart between the master earphone and the smart phone, the channels and the time slots of the eSCO link between the master earphone and the slave earphone and the eSCO link established between the master earphone and the smart phone are completely aligned.

In the embodiment shown in fig. 4, in the eSCO link established between the master and slave earphones, the master earphone does not transmit voice data to the slave earphone in the T0, T2 or T4 time slots, and the slave earphone does not transmit voice data to the master earphone in the T1, T3 or T5 time slots; instead, voice data sent by the smartphone is received from the headset at T0, T2, or T4 timeslots. That is, the communication between the master and slave earphones is not performed in the voice transmission/reception time slots (T0 and T1) between the master earphone and the smartphone and the voice retransmission time slots (T2 to T5) between the master earphone and the smartphone.

In the embodiment shown in fig. 4, if the voice data acquired by the master earphone is sent to the smartphone by using the master earphone, and the type of the voice data packet may be 2EV3, etc., the master earphone sends the acquired 2EV3 voice data packet to the smartphone in the T1, T3, or T5 time slot, and the slave earphone does not send the 2EV3 voice data packet in the T1, T3, or T5 time slot; if the 2EV3 voice data packet acquired from the earphone is transmitted to the smart phone from the earphone, the 2EV3 voice data packet acquired from the earphone is transmitted to the smart phone through the earphone in a T1, T3 or T5 time slot, and the main earphone does not transmit the 2EV3 voice data packet in a T1, T3 or T5 time slot. That is, within one interval TeSCO of the eSCO link, only one of the master and slave earphones transmits voice data to the smartphone at most.

Referring to fig. 4 again, taking the example of sending a 2EV3 voice data packet to the smart phone by using the main headset as an example, the following details are described in the process of the wireless headset and the smart phone performing a two-way voice call: at an anchor point of each eSCO link interval TeSCO, i.e., a T0 timeslot, the smart phone sends 2EV3 voice data to the wireless headset, i.e., corresponding to the eSCO link timeslot structure of the master and slave headsets in fig. 4, and the master and slave headsets receive a 2EV3 packet (RX 2EV3) sent by the smart phone at a T0 timeslot. Then, in a T1 time slot, the master earphone sends the acquired voice data 2EV3 packet to the smart phone (TX 2EV3), and simultaneously carries feedback information of whether the master earphone correctly receives the 2EV3 packet in the T0 time slot, and if the reply ACK information is correctly received, returns the NAK information if the reply NAK information is incorrectly received.

If the master earphone does not correctly receive the voice data sent by the smart phone, namely in the corresponding T1 or T3 time slot of the master earphone, the master earphone sends NAK information indicating that the NAK information is not correctly received; or the smart phone does not correctly receive the ACK acknowledgement message returned by the primary headset in the T1 or T3 time slot, the smart phone retransmits the 2EV3 voice data packet in the same T2 or T4 time slot as the T0 time slot.

If the smart phone does not correctly receive the voice data sent by the master earphone, i.e. the master earphone does not correctly receive the ACK acknowledgement information replied by the smart phone in the T2 or T4 time slot, the master earphone retransmits the 2EV3 voice data in the same time slot as the T1 in the corresponding T3 or T5 time slot.

Further, if the master earphone or the slave earphone does not correctly receive the voice data transmitted by the smartphone in the T0, T2, or T4 time slot, the master earphone and the slave earphone mutually forward the correctly received 2EV3 voice data transmitted by the smartphone by using the time slot between T6 and T7, the time slot between T6 and T9, or the time slot between T6 and T11 among the extended time slots for forwarding between the master earphone and the slave earphone, so that the master earphone and the slave earphone can correctly receive the 2EV3 voice data transmitted by the smartphone. Specifically, taking the extended time slot between T6 to T9 as an example, the master-slave headset mutual forwarding process is explained.

Firstly, in a T0 or T2 or T4 time slot (namely, a main earphone receiving time slot in a voice transceiving time slot and a voice retransmission time slot between a main earphone and the smart phone), one of the main earphone and the auxiliary earphone correctly receives 2EV3 voice data sent by the smart phone;

(1) if the master earphone correctly receives the 2EV3 voice data sent by the smart phone at T0 or T2 or T4, and the slave earphone does not correctly receive the 2EV3 voice data sent by the smart phone at T0 or T2 or T4, the master earphone forwards the correctly received 2EV3 voice data to the slave earphone in the T6 time slot; if the slave earphone correctly receives the 2EV3 voice data sent by the master earphone in the corresponding T6 time slot, a NULL packet carrying ACK information is sent to the master earphone in the T7 time slot, and the mutual forwarding process is ended; otherwise, if the slave earphone does not correctly receive the 2EV3 voice data sent by the master earphone in the corresponding T6 time slot, sending a NULL packet carrying NAK information in the T7 time slot, and requesting the master earphone to forward the 2EV3 voice data correctly received by the slave smartphone; thus, if the master earpiece receives a NULL packet of the NAK information or does not receive any valid packet at the corresponding T7 time slot, the correctly received 2EV3 voice data is forwarded to the slave earpiece at the T8 time slot; if the slave earphone correctly receives the 2EV3 voice packet forwarded by the master earphone in the T8 time slot, a NULL packet carrying ACK information is replied to the master earphone in the T9 time slot, so that the mutual forwarding process is ended, otherwise, the slave earphone does not send the packet related to forwarding in the T9 time slot, and the master earphone does not start the receiving related to forwarding in the T9 time slot.

(2) On the contrary, if the slave earphone correctly receives the 2EV3 voice data sent by the smartphone at T0 or T2 or T4, and the master earphone does not correctly receive the 2EV3 voice data sent by the smartphone at T0 or T2 or T4, the master earphone sends a NULL packet carrying NAK information in a T6 time slot to request the slave earphone to forward the 2EV3 voice data correctly received by the smartphone; after the slave earphone receives a NULL packet carrying NAK information sent by the master earphone in a T6 time slot or does not receive any effective packet, correctly received 2EV3 voice data of the smart phone is sent to the master earphone in a T7 time slot; if the master earphone correctly receives the 2EV3 voice data forwarded by the slave earphone in the T7 time slot, a NULL packet carrying ACK information is sent to the slave earphone in the T8 time slot, the mutual forwarding process is finished, otherwise, the NULL packet carrying NAK information is sent by the master earphone in the T8 time slot, and therefore the correctly received 2EV3 data packet of the smart phone is repeatedly forwarded to the master earphone in the T9 time slot by the slave earphone.

Secondly, in time slots T0, T2 or T4, the master earphone and the slave earphone both correctly receive 2EV3 voice data sent by the smart phone;

the master headset forwards correctly received 2EV3 voice data to the slave headset at the T6 time slot; if the slave earphone correctly receives the 2EV3 voice data forwarded by the master earphone at the time slot T6, a NULL packet carrying ACK information is sent to the master earphone at the time slot T7, and the mutual forwarding process is finished; if the slave headset does not receive any valid packet in the T6 slot, the correctly received 2EV3 voice data of the smartphone is transmitted to the master headset in the T7 slot.

Thirdly, in time slots of T0, T2 or T4, both the master earphone and the slave earphone do not correctly receive 2EV3 voice data sent by the smart phone;

the master earphone sends a NULL packet carrying NAK information to the slave earphone in a T6 time slot; after the slave earphone receives a NULL packet carrying NAK information sent by the master earphone in a T6 time slot or does not receive any effective packet, the slave earphone sends the NULL packet carrying ACK information to the master earphone in a T7 time slot, and therefore the mutual forwarding process is finished; then, as the master earphone and the slave earphone do not correctly receive the 2EV3 voice data sent by the smart phone in an eSCO link interval, the master earphone and the slave earphone respectively process the 2EV3 voice data packet received by the master earphone and the slave earphone through a packet loss processing compensation algorithm to recover the 2EV3 voice data packet, so that the correct 2EV3 voice data packet is respectively played through a voice output module of the master earphone and the slave earphone.

Please refer to fig. 5, which is a schematic diagram of another eSCO link timeslot structure according to an embodiment of the present invention. As compared with the link slot structure in fig. 4, the main difference includes two, one is that the extended time slot for mutual forwarding between the master and slave headsets can be implemented in advance into the retransmission window WeSCO. That is, if the master earpiece and the smartphone only need to occupy a portion of the retransmission window or not, the master earpiece and the slave earpiece may open an extended time slot for forwarding within the retransmission window WeSCO. Alternatively, in the link slot structure of fig. 3, the master earphone may transmit continuously in the T5 and T6 slots, i.e., immediately switch to the T6 slot to transmit to the slave earphone after transmitting to the smartphone in the T5 slot, whereas in the link slot structure of fig. 4, the master earphone switches to transmit to the slave earphone after transmitting to the smartphone in the T3 slot to the T5 slot. That is, two adjacent transmission time slots can be separated by 1 or more idle time slots, which can reduce the implementation difficulty. Other transceiving or forwarding methods are similar to the timeslot structure shown in fig. 4, and the transceiving or forwarding specific process of the link timeslot structure provided in fig. 4 is not described again in the present invention.

Optionally, in fig. 4 or 5, the 2EV3 voice data packet received by the smartphone in the T1, T3, or T5 timeslot is collected by the microphone of the master headset and sent through the master headset, and in order to improve the reliability of the call data sent by the wireless headset to the smartphone, the 2EV3 voice data may be collected by the microphone of the slave headset and sent to the smartphone through the slave headset. If 2EV3 voice data is collected by a microphone of the slave earphone and sent to the smart phone by the slave earphone, in fig. 3 or fig. 4, the slave earphone sends 2EV3 voice data to the smart phone in a T1, T3 or T5 time slot in the role of the master earphone, and the master earphone only receives in a T0, T2 or T4 time slot in the role of the slave earphone, but does not send in a T1, T3 or T5 time slot, and the transceiving or forwarding principles are the same.

The invention also provides a wireless earphone which comprises a master earphone and a slave earphone, wherein the master earphone and the slave earphone are in data interaction through wired or wireless connection. A main earphone in the wireless earphone establishes wireless connection with telephone equipment, and realizes bidirectional communication based on a first communication link; the master earphone also shares link information corresponding to the wireless connection between itself and the telephony device with the slave earphone; the slave earphone receives first voice data sent to the master earphone by the telephone equipment based on the link information shared by the master earphone; if one of the master earphone and the slave earphone does not correctly acquire the first voice data, the incorrectly acquired party receives the other party and forwards the first voice data.
