All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As will be appreciated by one skilled in the art, embodiments of the present invention may be embodied as a system, apparatus, device, method, or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the invention.
In the current bluetooth technology, the smart device can only be connected with one bluetooth device at the same time. For example, when bluetooth of a mobile phone is turned on, a plurality of surrounding bluetooth devices, such as a smart watch, a smart speaker, smart glasses, or a bluetooth headset, may be discovered. If the user needs the smart watch to detect and upload body data in real time, a Bluetooth link needs to be established on the mobile phone with the smart watch, and communication between the mobile phone and the Bluetooth earphone cannot be carried out at the moment. When a phone call comes in or a user wants to listen to music through a bluetooth headset, the existing technology needs the user to disconnect the link with the smart watch on the mobile phone and then select the bluetooth headset to establish the bluetooth link, which undoubtedly increases the waiting time of the user and greatly affects the use experience of the user; moreover, if the disconnection and re-establishment of the bluetooth link are required for each call, unnecessary waste of communication resources is also caused.
Fig. 1 is an application diagram of a wireless communication method applied between an intelligent device and a plurality of bluetooth devices according to an embodiment of the present application.
As shown in fig. 1, the plurality of bluetooth devices in this embodiment includes a bluetooth headset 13 and at least one other bluetooth device 12, the bluetooth headset 13 includes a first headset 131 and a second headset 132 that communicate via a wireless link 4, and the at least one bluetooth device 12 establishes communication with the smart device 11 via a first bluetooth link 1 and establishes a third bluetooth link 3 with the bluetooth headset 13.
When the intelligent device 11 needs to perform voice call or play audio through the bluetooth headset 13: the at least one bluetooth device 12 establishes a second bluetooth link 2 with the intelligent device 11, and sends the link parameter of the second bluetooth link 2 to the bluetooth headset 13 through a third bluetooth link 3, and the bluetooth headset 13 listens to the audio data sent by the intelligent device 11 by using the link parameter of the second bluetooth link 2; wherein the first bluetooth link 1 is not disconnected when the second bluetooth link 2 is established.
In the above embodiment, when the smart device 11 needs to connect the bluetooth headset 13 for a call or playing music, the smart device 11 does not need to disconnect the link with the bluetooth device 12, and does not need to reestablish the link with the bluetooth headset 13, and the bluetooth headset 13 only needs to "disguise" the bluetooth device 12 to communicate with the smart device 11, so that the time delay of playing music or a call can be reduced, and the bluetooth switching operation on the smart device 11 by a user is not needed, thereby greatly improving the user experience.
As shown in fig. 1, when the bluetooth device 12 establishes the first bluetooth link 1 with the smart device 11, the bluetooth device 12 may transmit the obtained user information to the smart device 11 in real time through the first bluetooth link 1, and the user may also transmit various control commands, such as various parameter modification commands, data upload time intervals, etc., to the bluetooth device 12 through the smart device 11.
In one embodiment, when the smart device 11 initiates a call or plays audio through the bluetooth headset 13, the second bluetooth link 2 is established between the bluetooth device 12 and the smart device 11 without disconnecting the first bluetooth link 1. When the intelligent device 11 initiates a voice call, the established second bluetooth link 2 is an SCO link (Synchronous Connection Oriented), that is, a Synchronous link established by a bluetooth SCO protocol; when the smart device 11 plays music, the established second bluetooth link 2 is an A2DP link (bluetooth Audio transmission model protocol), and the smart device 11 transmits stereo Audio to the bluetooth device 12 via the A2DP protocol, and plays music.
After the second bluetooth link 2 is established, the bluetooth device 12 sends the link parameters of the second bluetooth link 2 to the first headset 131 of the bluetooth headset 13, which is a master headset. The first earpiece 131 listens for voice or audio data etc. sent by the smart device 11 using the link parameters of the second bluetooth link 2. On the other hand, the second headset 132 may also obtain the link parameters of the second bluetooth link 2 via the wireless link 4, and listen to the audio data sent by the smart device 11 according to the link parameters of the second bluetooth link 2.
In one embodiment, the first headset 131 forwards the link parameters of the second bluetooth link 2 sent by the bluetooth device 12 to the second headset 132 via the wireless link 4, and the second headset 132 listens to the audio data sent by the smart device 11 by using the obtained link parameters of the second bluetooth link 2. In this embodiment, the link parameters of the second bluetooth link 2 include the bluetooth address of the smart device 11, the bluetooth address of the bluetooth device 12, the encryption parameters of the second bluetooth link 2, and the piconet clock of the second bluetooth link 2.
In another embodiment, the first headset 131 sends the link parameters of the third bluetooth link 3 to the second headset 132 via the wireless link 4, and the second headset 132 listens to the link parameters of the second bluetooth link 2 sent by the bluetooth device 12 using the link parameters of the third bluetooth link 3. Thus, the second headset 132 further listens for audio data sent by the smart device 11 according to the link parameters of the second bluetooth link 2 that are listened to. In this embodiment, the link parameters of the third bluetooth link 3 include the bluetooth address of the bluetooth device 12, the encryption parameters of the third bluetooth link 3, and the piconet clock of the third bluetooth link 3. In this embodiment, when the first earphone 131 receives the link parameter related to the second bluetooth link 2, the second earphone 132 can also receive the link parameter related to the second bluetooth link 2, thereby avoiding the link parameter related to the second bluetooth link 2 being transmitted to the first earphone 131 first and then to the second earphone 132. Thus, this embodiment reduces transmission latency so that the ear piece can receive the call voice or music from the smart device with less latency.
When the first earphone 131 and the second earphone 132 communicate with the smart device 11 by listening to the second bluetooth link 2, the bluetooth device 12 has disregarded the second bluetooth link 2, and it can continue to communicate data, such as upload data, with the smart device 11 via the first bluetooth link 1. And when the first earphone 131 and the second earphone 132 both correctly receive the audio data sent by the smart device 11, the first earphone 131 or the second earphone 132 sends ACK to the smart device 11, otherwise, the first earphone 131 or the second earphone 132 sends NACK to the smart device 11. Since the link parameters of the second bluetooth link 2 include the bluetooth address of the bluetooth device 12, the second headset 132 may masquerade as the bluetooth device 12 sending ACK/NACK to the smart device 11.
In another embodiment, a third bluetooth link 3 is established between the bluetooth device 12 and the bluetooth headset 13, and the bluetooth device 12 may play music to the bluetooth headset 13. At this time, if the smart device 11 has a call coming, the smart device 11 and the bluetooth device 12 will establish an SCO connection, the bluetooth device 12 disconnects the music playing with the bluetooth headset 13 and transmits the link information related to the SCO connection (i.e. the second bluetooth link 2) to the bluetooth headset 13, and the bluetooth headset 13 receives the call from the smart device 11 accordingly. Furthermore, replying the ACK/NACK packet to the mobile phone is also completed by the bluetooth headset 13, and the uplink voice of the user sent to the smart device 11 is also collected by the MIC on the bluetooth headset 13, disguised as the bluetooth device 12 (using the relevant link information of the SCO connection) by the bluetooth headset 13, and sent to the smart device 11. The bluetooth device 12, as a master device between the smart device 11 and the bluetooth headset 13, may immediately stop playing music with the bluetooth headset 13, and seamlessly (or with a very low delay) switch to the bluetooth headset 13 to receive a call, and does not need any user intervention on the smart device side, thereby improving user experience.
In yet another embodiment, if the channel of the first bluetooth link 1 weakens during the communication or audio playing between the smart device 11 and the bluetooth headset 13, the bluetooth device 12 may also send the second data acquired by the smart device to the bluetooth headset 13 through the third bluetooth link 3, and the bluetooth headset 13 sends the second data to the smart device 11 by using the link parameters of the second bluetooth link 2 that are actually heard. In this embodiment, the second data may be user data with a small data volume, generally speaking, the requirement on real-time performance is not high, and the influence on the communication between the smart device 11 and the bluetooth headset 13 is small.
In an application of the wireless communication method shown in fig. 1, the smart device 11 may be a smart phone at a user end, and has bluetooth communication and voice communication functions; the bluetooth device 12 may be an intelligent bluetooth device such as an intelligent watch, an intelligent speaker, an intelligent glasses, etc., and on one hand, the bluetooth device may establish a bluetooth link with the intelligent device 11 for data interaction, and on the other hand, the bluetooth device may also establish a bluetooth link with the bluetooth headset 13, and serve as a relay device between the intelligent device and the bluetooth headset, thereby reducing the time delay of communication or music playing.
In this application, a typical application scenario is shown in fig. 2, the smart device is a smart phone 21, and the bluetooth device is a smart watch 22. The smart watch 22 establishes communication with the smart phone 21 through the first bluetooth link 1, and sends various user information (such as heart rate, step counting, sleep state, body temperature, positioning information, and the like) to the smart phone 11 through the first bluetooth link 1; furthermore, the smart watch 22 may be connected to the wireless bluetooth headset 23 via the third bluetooth link 3.
When the smart watch 22 establishes a call with the smart phone 11 or plays a second bluetooth link 2 of music, the smart watch 22 transmits the relevant link parameters (including the bluetooth address of the smart phone 11, the encryption parameter of the second bluetooth link 2, the piconet clock of the second bluetooth link 2, and other parameters) of the second bluetooth link 2 to the first headset 231 through the second bluetooth link 2 between the smart watch 22 and the smart phone 11; the first earphone 231 receives the audio data sent by the smart phone 11 in the second bluetooth link 2 by using the related link parameters of the second bluetooth link 2.
In this embodiment, when the smart phone 11 initiates a call, the established second bluetooth link 2 is an SCO link; when the smartphone 11 plays music, the established second bluetooth link 2 is an A2DP link, and the smartphone 11 transmits stereo audio to the smartwatch 22 or the bluetooth headset 23 via the A2DP protocol, plays music, and so on.
A wireless link 4 is established between the first earphone 231 and the second earphone 232, and the first earphone 231 transmits link parameters related to the third bluetooth link 3 (including parameters such as the bluetooth address of the smart watch 22, the encryption parameter of the third bluetooth link 3 between the smart watch 22 and the first earphone 131, and the piconet clock of the third bluetooth link 3) to the second earphone 232 through the wireless link 4; the second headset 232 receives the bluetooth frame sent by the smart watch 221 in the third bluetooth link 3 by using the relevant link parameters of the third bluetooth link 3. Therefore, when the first headset 231 receives the link parameter related to the second bluetooth link 2, the second headset 232 can also receive the link parameter related to the second bluetooth link 2. In this way, it is avoided that the link parameters associated with the second bluetooth link 2 are transmitted to the first earphone 231 and then to the second earphone 232, thereby reducing the transmission delay and enabling the earphone to receive the call voice or music from the mobile phone with less delay.
Then, for the second bluetooth link 2, it is actually the relation of the smartphone 21, the first headset 231, and the second headset 232. The first headset 231, the second headset 232 pretend to be the smart watch 22 itself, communicating with the smartphone 21. The first headphone 231 receives the data correctly and sends an indication frame (which may be an ACK packet or an ECC packet) to the second headphone 232. The first earpiece 231, the second earpiece 232 both receive correctly, giving an ACK back to the smartphone 21, otherwise giving a NACK back to the smartphone 21. At this point, the smart watch 22 gives the second bluetooth link 2 to the bluetooth headset 23, and does not itself disregard the second bluetooth link 2.
According to the embodiment, a plurality of mobile phones on the market at present are connected with the intelligent watch at ordinary times, information such as step counting, heartbeat, body temperature and the like can be obtained from the intelligent watch in real time, and when a user wants to play music through the mobile phone or the mobile phone has a call to come in, the mobile phone does not need to disconnect the Bluetooth link with the intelligent watch and reestablish the Bluetooth link with the earphone. Therefore, the time delay of starting playing music or calling is reduced, the first Bluetooth link 1 between the mobile phone and the smart watch can continue, and the mobile phone can continue to obtain information such as step counting, heartbeat and the like from the watch. In addition, the user does not need to manually disconnect the Bluetooth link with the watch at the mobile phone side and select the corresponding earphone device to establish the Bluetooth link, so that the user experience is greatly improved. On the other hand, even though the mobile phone can be connected with the earphone and the watch at the same time, in the prior art, if the mobile phone receives a call, the user is required to select which bluetooth device to transmit the call to, and the use experience of the user is also greatly influenced. In the embodiment of the invention, when the mobile phone receives the call, the SCO link is established between the watch and the mobile phone, and the Bluetooth headset realizes the voice call with the mobile phone by monitoring the SCO link, so that no operation is required by a user, and the user experience is greatly improved.
In the embodiment shown in fig. 2, when the smart watch 22 plays music to the bluetooth headset 23 through the third bluetooth link 3, if there is a call coming in the mobile phone 21 at this time, the mobile phone 21 establishes an SCO connection with the smart watch 22, and the smart watch 22 disconnects music playing with the bluetooth headset 23. The link information associated with the SCO connection is passed to the bluetooth headset 23, whereupon the bluetooth headset 23 receives the call from the handset 21. Replying the ACK/NACK packet to the mobile phone 21 is also completed by the bluetooth headset 23, the uplink voice of the user sent to the mobile phone 21 is also collected by the MIC on the bluetooth headset 23, and the bluetooth headset 23 pretends to be the smart watch 22 (using the relevant link information of the SCO connection), and sends the smart watch 22 to the mobile phone 21. The smart watch 22, as a master device in the mobile phone 21 and the bluetooth headset 23, may immediately stop playing music with the headset, and seamlessly (or with a very low delay) switch to the bluetooth headset 23 to receive a call, and does not need any user intervention on the smart device side, thereby improving user experience.
In the embodiment shown in fig. 2, after the bluetooth headset 23 is disguised as the smart watch 22 communicating with the mobile phone 21, various user information (e.g., heart rate, step count, sleep status, body temperature, positioning information) on the smart watch 22 may be transmitted to the bluetooth headset 23 (e.g., a master headset, i.e., a headset that sends ACK/NACK back to the mobile phone 21) through the connection between the smart watch 22 and the bluetooth headset 23, and then the bluetooth headset 23 forwards the user information to the mobile phone 21. Because the user information on the smart watch 22 generally has a small data volume and a low requirement on real-time performance, the influence on the communication between the mobile phone 21 and the bluetooth headset 23 is small. Meanwhile, the communication between the cell phone 21 and the smart watch 22 is not interrupted.
In the embodiments shown in fig. 1 and fig. 2, it should be noted that the smart device (mobile phone), the bluetooth device (smart watch) and the bluetooth headset communicate independently with each other in different time periods of respective bluetooth frames to avoid causing communication interference.

wherein the first Bluetooth link is not broken when the second Bluetooth link is established.
In this embodiment, it can be understood that the logic functions of the three bluetooth logic modules 31, 32, and 33 are all implemented in the bluetooth module 30, but the three bluetooth logic modules can be implemented in a time-sharing manner, so as to avoid causing communication interference.
In some embodiments, the bluetooth module 30 sends the link parameter of the second bluetooth link to the first headset as a master headset, and the first headset listens to the audio data sent by the smart device by using the link parameter of the second bluetooth link; and the second earphone acquires the link parameters of the second Bluetooth link through a wireless link and listens audio data sent by the intelligent equipment according to the link parameters of the second Bluetooth link.
