Description

Communication method, device, equipment and system of dual-wireless Bluetooth communication network

Technical Field

The present invention relates to the field of bluetooth communication technologies, and in particular, to a communication method, apparatus, device, and system for a dual-wireless bluetooth communication network.

Background

In the application of dual-wireless bluetooth communication, such as dual-wireless bluetooth headset, dual-wireless bluetooth speaker, etc., three bluetooth devices are required to communicate through at least two bluetooth links, thereby forming a dual-wireless bluetooth device communication system. That is, the dual wireless bluetooth device communication system includes three bluetooth devices, one of which is a bluetooth sound source device (e.g., a mobile phone, a notebook computer, etc.), and two wireless bluetooth devices that play simultaneously (e.g., a dual wireless bluetooth headset, a dual wireless bluetooth speaker, etc.), both of which are wireless bluetooth devices, and a bluetooth playback device connected to the bluetooth sound source device is generally referred to as a bluetooth playback master device, and a bluetooth playback device connected to the bluetooth playback master device and listening to the bluetooth sound source device is generally referred to as a bluetooth playback slave device.

In bluetooth communication networks there is also a division of network master devices and network slave devices. In the Bluetooth standard protocol, a network Master device (the Master of the piconet, master) will dominate the communication time sequence between networks, manage Bluetooth communication links and have active transmission capability; the network Slave (the slaves in the piconet, slave) only transmits passively, and the network master data packet is received. In the existing dual-wireless Bluetooth communication system, bluetooth sound source equipment is generally adopted as network master equipment, dual-Bluetooth playing equipment is used as network slave equipment for communication, one of the Bluetooth sound source equipment and the dual-Bluetooth playing equipment is connected, the other Bluetooth playing equipment receives audio data in a mode of monitoring the sound source equipment, and the sound source equipment and the Bluetooth playing slave equipment do not directly communicate.

As shown in fig. 1a, the bluetooth sound source device 101' is a network Master device (the Master of the piconet, master), and the first bluetooth device 102' and the second bluetooth device 103' establish a link in the state of a network Slave device (the slaves in the piconet, slave). Among network slave devices composed of a first bluetooth device 102' and a second bluetooth device 103', the first bluetooth device 102' is a bluetooth playing master device, establishes connection with the network master device, namely a bluetooth sound source device 101', and receives audio data sent by the bluetooth sound source device 101' through a first bluetooth link; the second bluetooth device 103' is a bluetooth playing slave device, and receives audio data in a manner of monitoring the sound source device through a bluetooth monitoring link; the first bluetooth device 102 'and the second bluetooth device 103' are connected via a second bluetooth link, and may perform operations such as data forwarding.

The bluetooth sound source device 101 'and the bluetooth playing master and slave devices (102', 103 ') are usually provided by different manufacturers, and if the bluetooth sound source device 101' does not have good performance problems such as communication quality and interference among the three, for example, communication is performed on a frequency point with serious interference, whether the effect of dual bluetooth communication is optimal or not can be hardly estimated, and the product competitiveness is affected. However, since there is also a second bluetooth link connecting the bluetooth playback master device and the bluetooth playback slave device in the network slave device, and the bluetooth sound source device 101 'cannot learn the communication condition of the second bluetooth link, it is difficult for the bluetooth sound source device 101' as the network master device to evaluate performance problems such as dual bluetooth communication quality and interference.

In addition, in the existing network, the bluetooth sound source device 101 'may continuously retransmit audio data, so that the bluetooth playing master and slave devices (102', 103 ') receive and monitor, thereby increasing the power consumption of the bluetooth sound source device 101'; in addition, the three components are simultaneously performing data transmission and reception operations, which results in signal interference.

Example group 1

In order to reduce the problems of bandwidth waste and large power consumption caused by the fact that the bluetooth sound source device always transmits data in the dual-wireless bluetooth communication network, the embodiment discloses a communication method of the dual-wireless bluetooth communication network, please refer to fig. 1b, which is a schematic diagram of the dual-wireless bluetooth communication network structure disclosed in the embodiment, wherein the dual-wireless bluetooth communication network is formed by the bluetooth sound source device 101, the bluetooth playing master device 102 and the bluetooth playing slave device 103, wherein:

the first bluetooth link is used for data interaction between the bluetooth playing main device 102 and the bluetooth sound source device 101; the second bluetooth link is used for data interaction between the bluetooth playing master device 102 and the bluetooth playing slave device 103; the bluetooth listening link is used for bluetooth playback slave device 103 to listen to audio data provided by bluetooth sound source device 101. In this embodiment, the bluetooth sound source device 101 may be a device with a bluetooth communication function and an audio providing function, such as a mobile phone, a tablet computer, a notebook, and an audio-visual player; the bluetooth playing master device 102 and the bluetooth playing slave device 103 are used for playing audio provided by the bluetooth sound source device 101, and the bluetooth playing master device 102 and the bluetooth playing slave device 103 may be paired bluetooth headphones, bluetooth speakers, and other playing devices with bluetooth communication functions. In a specific embodiment, the bluetooth playing master device 102 performs data interaction with the bluetooth sound source device 101 through a first bluetooth link, and the bluetooth playing slave device 103 monitors audio data sent by the bluetooth sound source device 101 through a bluetooth listening link.

Referring to fig. 2a, a flowchart of a communication method is disclosed in this embodiment, where the communication method is used for a bluetooth playing master device of a dual-wireless bluetooth communication network, and the communication method includes:

step S201: a first bluetooth link is established with the bluetooth sound source device 101. Referring to fig. 1b, in the present embodiment, in the first bluetooth link, the bluetooth playing Master device 102 is used as a network Master device (the Master of the piconet, master) for controlling the communication flow of the dual-wireless bluetooth communication network, and the bluetooth sound source device 101 and the bluetooth playing Slave device 103 are used as network Slave devices (the slaves in the piconet, slave) of the dual-wireless bluetooth communication network. That is, in the dual wireless bluetooth communication network, operations of transmitting and receiving data, frequency hopping, and the like of the bluetooth sound source device 101, the bluetooth playback slave device 103 are controlled by the bluetooth playback master device 102.

In a specific embodiment, the bluetooth playback master device 102 may be made to be a network master device when the first bluetooth link is requested to be established. Specifically, step S201 includes: transmitting a link establishment request for establishing a first bluetooth link to the bluetooth sound source device 101, wherein the link establishment request indicates that the bluetooth playing master device 102 is a network master device; receiving a response of the bluetooth sound source device 101 agreeing to the link establishment request; a first bluetooth link is established. According to the bluetooth communication standard protocol, the party initiating the link establishment request is the network master device, so in this embodiment, the bluetooth playing master device 102 sends a link establishment request for establishing the first bluetooth link to the bluetooth sound source device 101, and after establishing the first bluetooth link, the bluetooth playing master device 102 naturally becomes the network master device.

Step S202: an audio data request instruction is transmitted to the bluetooth sound source device 101 through the first bluetooth link. So that the bluetooth sound source device 101 performs a data transmission operation based on the audio data request instruction with the bluetooth playback master device 102 and the bluetooth playback slave device 103. For example, when the bluetooth playback master device 102 transmits an instruction indicating to transmit audio data, based on the instruction, the bluetooth sound source device 101 transmits audio data packets to the bluetooth playback master device 102 and the bluetooth playback slave device 103, at which time the bluetooth playback master device 102 may receive the audio data packets transmitted by the bluetooth sound source device 101, and the bluetooth playback slave device 103 may monitor the audio data packets transmitted by the bluetooth sound source device 101; for another example, when the bluetooth playback master device 102 and the bluetooth playback slave device 103 have a packet loss condition, and the bluetooth sound source device 101 needs to retransmit an audio packet, the bluetooth sound source device 101 retransmits the audio packet to the bluetooth playback master device 102 and the bluetooth playback slave device 103 based on an instruction indicating that the audio packet is retransmitted by the bluetooth playback master device 102.

Step S203: an audio data packet corresponding to the audio data request instruction transmitted by the bluetooth sound source device 101 is received through the first bluetooth link. In a specific embodiment, after receiving the audio data request instruction, the bluetooth sound source device 101 sends an audio data packet based on the audio data request instruction, where the bluetooth playing master device 102 may receive, through the first bluetooth link, the audio data packet sent by the bluetooth sound source device 101, and during this time, the bluetooth playing slave device 103 may monitor, through the bluetooth listening link, the audio data packet sent by the bluetooth sound source device 101.

Step S204: a state is maintained in which a request instruction is not transmitted to the bluetooth sound source device 101. Specifically, before the bluetooth-playing master device 102 and the bluetooth-playing slave device 103 have a need to retransmit the audio data packet, the bluetooth-playing master device 102 maintains a state in which an audio data request instruction is not transmitted to the bluetooth-source device 101, so that, during this period, the bluetooth-source device 101 remains in a state in which the audio data packet is not retransmitted based on the retransmission audio data request instruction not being received; during this time, the bluetooth sound source device 101 maintains a state of not transmitting a new audio data packet until a new audio data request is not received.

In this embodiment, since the bluetooth playing master device 102 is a network master device of the dual-wireless bluetooth communication network, and the bluetooth sound source device 101 is a network slave device of the dual-wireless bluetooth communication network, the bluetooth sound source device 101 needs to perform data transmission according to the instruction of the bluetooth playing master device 102. That is, the bluetooth sound source device 101 transmits the audio data corresponding to the audio data request instruction after receiving the audio data request instruction transmitted by the bluetooth play master device 102. The bluetooth sound source device 101 is requested to transmit audio data by the bluetooth play master device 102, which can reduce bandwidth consumption of the bluetooth sound source device 101 compared with the method in which the bluetooth sound source device 101 actively transmits audio data all the time in the prior art.

Referring to fig. 2b, a flowchart of a communication method is disclosed in this embodiment, where the communication method is used for a bluetooth playing master device of a dual-wireless bluetooth communication network, and the communication method includes:

step S211: a first bluetooth link is established with the bluetooth sound source device 101 based on the request of the bluetooth sound source device 101. In this embodiment, a bluetooth sound source device 101 initiates a request for establishing a first bluetooth link, and after agreeing to the request for establishing, a bluetooth play master device 102 establishes the first bluetooth link with the bluetooth sound source device 101; at this time, since the bluetooth sound source device 101 initiates the establishment request, in the first bluetooth link, the bluetooth sound source device 101 functions as a network Master device (the Master of the piconet, master) that controls the communication flow of the dual wireless bluetooth communication network, and the bluetooth playback Master device 102 and the bluetooth playback Slave device 103 function as network Slave devices (the slaves in the piconet, slave) of the dual wireless bluetooth communication network according to the bluetooth standard protocol.

Step S212: a network master-slave switching request is transmitted to the bluetooth sound source device 101. In this embodiment, the network master-slave switching request (lmp_switch_req) indicates that the bluetooth playback master device 102 and the bluetooth sound source device 101 switch master-slave roles in the first bluetooth link, and the network master-slave switching request lmp_switch_req includes master-slave switching time information. In a specific implementation process, when the bluetooth sound source device 101 initiates to the bluetooth playing Master device 102 to establish the first bluetooth link, the bluetooth sound source device 101 and the bluetooth playing Master device 102 can both know their own network roles, that is, the bluetooth sound source device 101 is a network Master device (the Master of the piconet, master), and the bluetooth playing Master device 102 is a network Slave device (the slaves in the piconet, slave). In order to make the bluetooth playback master device 102 a network master device, after the first bluetooth link is established, a network master-slave switching request may be sent to the bluetooth sound source device 101 to implement master-slave role switching of the network device.

Step S213: and receiving a response of the Bluetooth sound source device 101 agreeing to the network master-slave switching request. After receiving the network master-slave switching request lmp_switch_req, the bluetooth sound source device 101 sends a response for granting the network master-slave switching request lmp_switch_req to the bluetooth playback master device 102 through the first bluetooth link.

Step S214: when the master-slave switching time arrives, master-slave switching is performed with the bluetooth sound source device 101. Because the network master-slave switching request lmp_switch_req contains master-slave switching time information, the bluetooth sound source device 101 can know the master-slave switching time; when the master-slave switching time arrives, the bluetooth playing master device 102 performs master-slave switching with the bluetooth sound source device 101, so that in the first bluetooth link, the bluetooth playing master device 102 is used as a network master device (the master of the piconet) for controlling the communication flow of the dual-wireless bluetooth communication network, and the bluetooth sound source device 101 and the bluetooth playing slave device 103 are used as network slave devices (the slaves in the piconet) of the dual-wireless bluetooth communication network, thereby realizing the identity switching of master-slave roles of the bluetooth sound source device 101 and the bluetooth playing slave device 103 in the network.

Step S202: an audio data request instruction is transmitted to the bluetooth sound source device 101 through the first bluetooth link. Wherein, the bluetooth sound source device 101 sends an audio data packet to the bluetooth playing master device 102 and the bluetooth playing slave device 103 in the dual wireless bluetooth communication network based on the audio data request instruction. Specifically, please refer to the description of the above embodiments, which is not repeated herein.

Step S203: an audio data packet corresponding to the audio data request instruction transmitted by the bluetooth sound source device 101 is received through the first bluetooth link. During this time, the bluetooth playback slave device 103 listens for audio data packets via the bluetooth listening link. Specifically, please refer to the description of the above embodiments, which is not repeated herein.

In an alternative embodiment, after performing step S201 or step S214, that is, after the bluetooth playback Master device 102 is a network Master device (the Master of the piconet, master) that controls a communication flow of the dual wireless bluetooth communication network, the communication method further includes: transmitting a frequency hopping instruction to the Bluetooth sound source device 101; the frequency hopping operation is performed in the frequency hopping sequence corresponding to the frequency hopping instruction, and during this time, the bluetooth sound source device 101 also performs the frequency hopping operation in the frequency hopping sequence corresponding to the frequency hopping instruction. In a specific embodiment, the bluetooth playing master device 102 may perform the frequency hopping indication according to the communication quality conditions of the first bluetooth link and the second bluetooth link, which are known by the bluetooth playing master device, or may send the frequency hopping indication according to the frequency hopping request of the bluetooth playing slave device 103. Specifically, the bluetooth playing master device 102 and the bluetooth playing slave device 103 perform data interaction through a second bluetooth link; before transmitting the frequency hopping instruction to the bluetooth sound source device 101, it includes: respectively determining communication quality of a first Bluetooth link and a second Bluetooth link; and generating a frequency hopping instruction according to the communication quality. In this embodiment, the communication quality can be evaluated by whether there is interference between the bluetooth playback master device 102 and the bluetooth sound source device 101 and/or the bluetooth playback slave device 103, the signal-to-noise ratio of the communication, or the like. Of course, when the communication quality of the bluetooth playback slave device 103 is poor (for example, when it is interfered), the bluetooth playback slave device 103 may also make a frequency hopping request to the bluetooth playback master device 102, specifically, before sending a frequency hopping instruction to the bluetooth sound source device 101, including: receiving a frequency hopping request sent by the Bluetooth playing slave device 103; and generating a frequency hopping instruction according to the frequency hopping request. In the implementation process, after receiving the frequency hopping request sent by the bluetooth playing slave device 103, the communication quality of the first bluetooth link and the second bluetooth link may be determined respectively, when the communication quality of the first bluetooth link and the second bluetooth link are both poor, the first bluetooth link and the second bluetooth link may be instructed to perform frequency hopping operation, and when only the communication quality of the second bluetooth link is both poor, the second bluetooth link may be instructed to perform frequency hopping operation.

In this embodiment, since the bluetooth playing master device 102 performs data interaction with the bluetooth sound source device 101 through the first bluetooth link, and the bluetooth playing master device 102 performs data interaction with the bluetooth playing slave device 103 through the second bluetooth link, the bluetooth playing master device 102 may know the communication quality conditions of the first bluetooth link and the second bluetooth link between the bluetooth playing master device and the bluetooth sound source device 101 and the bluetooth playing slave device 103, and compared with the prior art, the scheme of this embodiment may perform frequency hopping indication according to the communication quality of the whole network when the bluetooth sound source device 101 only knows the communication quality of the first bluetooth link and does not know the communication quality of the second bluetooth link, so that the frequency hopping is more global.

According to the communication method of the dual-wireless Bluetooth communication network disclosed by the embodiment, in the dual-wireless Bluetooth communication network, compared with the prior art, bluetooth sound source equipment is used as network master equipment, in the method, because the Bluetooth playing master equipment is the network master equipment of the dual-wireless Bluetooth communication network, after an audio data request instruction is sent to the Bluetooth sound source equipment through a first Bluetooth link, audio data packet sending operation based on the audio data request instruction is carried out among the Bluetooth sound source equipment, the Bluetooth playing master equipment and Bluetooth playing slave equipment; the bluetooth sound source device remains in a state of not retransmitting the audio data packet or not transmitting a new audio data packet until the bluetooth play back master device has a need to retransmit the audio data packet or a new audio data request. Therefore, the problems of bandwidth waste and high power consumption caused by always sending data when the Bluetooth sound source equipment is used as a network master equipment are avoided. In addition, because the communication flow of the dual-wireless Bluetooth communication network is controlled by the Bluetooth playing master device, the communication operation of the Bluetooth sound source device is performed based on the audio data request instruction, and the Bluetooth playing master device can reduce communication interference caused by actively transmitting data by the Bluetooth sound source device during the communication with the Bluetooth playing slave device.

Referring to fig. 3, a flowchart of a communication method for a bluetooth sound source device is disclosed in this embodiment. The communication method comprises the following steps:

step S301: a first bluetooth link is established with bluetooth playback master device 102. In this embodiment, in the first bluetooth link, the bluetooth playback Master device 102 serves as a network Master device (the Master of the piconet, master) that controls the communication flow of the dual-wireless bluetooth communication network, and the bluetooth sound source device 101 and the bluetooth playback Slave device 103 serve as network Slave devices (the slaves in the piconet, slave) of the dual-wireless bluetooth communication network. Specifically, please refer to the description of the above embodiments, which is not repeated herein.

In one embodiment, the bluetooth playing master device 102 may become the network master device by receiving a request from the bluetooth playing master device 102 to establish a first bluetooth link, and then establishing the first bluetooth link with the bluetooth playing master device 102. Specifically, please refer to the description of the above embodiments, which is not repeated herein.

In another embodiment, after the first bluetooth link is established, the bluetooth playing master device 102 may be made to be a network master device by accepting a master-slave switching request of the bluetooth playing master device 102. Specifically, a network master-slave role switching request lmp_switch_req sent by the bluetooth playing master device 102 is received, where the network master-slave switching request lmp_switch_req indicates that the bluetooth playing master device 102 and the bluetooth sound source device 101 switch master-slave roles in the first bluetooth link, and the network master-slave switching request lmp_switch_req includes master-slave switching time information; transmitting a response agreeing to the network master-slave switching request LMP_switch_req to the Bluetooth play master device 102; when the master-slave switching time arrives, a network master-slave role switching operation is performed with the bluetooth playback master device 102 so that, in the first bluetooth link, the bluetooth playback master device 102 functions as a network master device the master of the piconet that controls the communication flow of the dual wireless bluetooth communication network, and the bluetooth sound source device 101 and the bluetooth playback slave device 103 function as network slave devices the slaves in the piconet of the dual wireless bluetooth communication network. Specifically, please refer to the description of the above embodiments, which is not repeated herein.

Step S302: the audio data request instruction sent by the bluetooth playback master device 102 is received via the first bluetooth link. In this embodiment, after the first bluetooth link is established with the bluetooth playback master device 102, the operation of sending the audio data packet by the bluetooth sound source device 101 is performed based on the audio data request instruction sent by the bluetooth playback master device 102. Specifically, please refer to the description of the above embodiments, which is not repeated herein.

Step S303: an audio data packet is transmitted to the bluetooth playback master device 102 and the bluetooth playback slave device 103 in the dual wireless bluetooth communication network based on the audio data request instruction. Wherein, the bluetooth playing master device 102 receives the audio data packet through the first bluetooth link, and during this period, the bluetooth playing slave device 103 listens for the audio data packet through the bluetooth listening link. For example, when the bluetooth playback master device 102 transmits an instruction indicating transmission of audio data, the bluetooth sound source device 101 transmits an audio data packet to the bluetooth playback master device 102 and the bluetooth playback slave device 103 according to the instruction; for another example, when the bluetooth playback master device 102 and the bluetooth playback slave device 103 have a packet loss condition, and the bluetooth playback master device 102 sends an instruction for retransmitting the audio data when the bluetooth sound source device 101 needs to retransmit the audio data, the bluetooth sound source device 101 retransmits the audio data packet to the bluetooth playback master device 102 and the bluetooth playback slave device 103 according to the instruction.

Step S304: the non-retransmitted data and non-transmitted new audio data packet states are maintained. Specifically, based on the retransmission audio data request instruction transmitted from the bluetooth-play-master device 102 not being received, the bluetooth-sound source device 101 remains in a state of not retransmitting the audio data packet, during which the bluetooth-sound source device 101 remains in a state of not transmitting a new audio data packet until a new audio data request is not received.

In order to save bandwidth consumption of the audio source device, after step S303, that is, after transmitting the audio data packet corresponding to the request instruction based on the audio data request instruction, the method further includes: before receiving the audio data request instruction transmitted next by the bluetooth playback master device 102, the operation of transmitting audio data to the bluetooth playback master device 102 and the second bluetooth device 103 is stopped. In this embodiment, the bluetooth sound source device 101 needs to perform data transmission according to the instruction of the bluetooth playback master device 102. That is, the bluetooth sound source device 101, after receiving the audio data request instruction transmitted by the bluetooth playback master device 102, transmits an audio data packet corresponding to the audio data request instruction, and stops transmitting the audio data packet to the bluetooth playback master device 102 and the bluetooth playback slave device 103 before not receiving the audio data request instruction. The Bluetooth sound source equipment can be prevented from retransmitting the audio data packet all the time, and the bandwidth consumption of the sound source equipment is saved.

In another embodiment, the communication method further comprises: receiving a frequency hopping instruction sent by the Bluetooth playing main device 102; and performing frequency hopping operation according to the frequency hopping sequence corresponding to the frequency hopping instruction. Specifically, please refer to the description of the above embodiments, which is not repeated herein.

According to the communication method of the dual-wireless Bluetooth communication network disclosed by the embodiment, audio data packet sending operation based on audio data request instructions is performed between Bluetooth sound source equipment and Bluetooth playing master equipment and Bluetooth playing slave equipment; the bluetooth sound source device remains in a state of not retransmitting the audio data packet or not transmitting a new audio data packet until the bluetooth play back master device has a need to retransmit the audio data packet or a new audio data request. Therefore, the problems of bandwidth waste and high power consumption caused by always sending data when the Bluetooth sound source equipment is used as a network master equipment are avoided. In addition, because the communication flow of the dual-wireless Bluetooth communication network is controlled by the Bluetooth playing master device, the communication operation of the Bluetooth sound source device is performed based on the audio data request instruction, and the Bluetooth playing master device can reduce communication interference caused by actively transmitting data by the Bluetooth sound source device during the communication with the Bluetooth playing slave device.
