Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The technical scheme is suitable for Bluetooth communication scenes, particularly suitable for the scenes that a master Bluetooth device and a slave Bluetooth device carry out BIG communication in the Bluetooth communication scenes, wherein the master Bluetooth device is the Bluetooth device which searches and actively establishes connection in the Bluetooth communication scenes, and the master Bluetooth device can search surrounding Bluetooth devices and select the Bluetooth devices to be connected to carry out pairing connection; a slave bluetooth device refers to a device waiting to be searched for a connection by a master bluetooth device in a bluetooth communication scenario. Specifically, the main bluetooth device may be a mobile phone, a notebook computer, etc.; from bluetooth device can be earphone, intelligent stereo set etc. this application does not do the restriction. It should be appreciated that a bluetooth device may either initiate a communication connection as a master device or receive a communication connection as a slave device; a bluetooth device may also act as both a master and a slave.
The technical solution of the present application may be applied to a bluetooth system composed of a master bluetooth device and slave bluetooth devices, as shown in fig. 1, the bluetooth system 10 may include a master bluetooth device 101 and a BIG102, where the BIG includes a plurality of slave bluetooth devices (E1, E2, E3, …, en), n is the number of slave bluetooth devices in the BIG, and n may theoretically be any integer greater than 0.
The BIS link is a unidirectional broadcast link, the master Bluetooth device can send BIS signals to each slave Bluetooth device in the BIG through the BIS link, the BIS signals are unidirectional signals, and the master Bluetooth device sends the BIS signals in a broadcast mode, so that time synchronization of the BIS signals belonging to the same BIG is realized, and time sequence reference data in the same BIG is shared. Wherein the master bluetooth device may create one or more BIG and broadcast BIG information (BIG fo) of the created BIG; the slave Bluetooth device can acquire BIG information by interception on a broadcast channel so as to join in BIG created by the master Bluetooth device, and further receive BIS signals sent by the master Bluetooth device according to the BIG information.
The technical scheme of the application is specifically applied to the main Bluetooth equipment in the Bluetooth system. The following specifically describes the technical scheme of the present application.
Referring to fig. 2, fig. 2 is a schematic flow chart of a bluetooth communication method according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:
s201, acquiring a broadcast synchronous stream data packet to be broadcasted.
Here, the BIS data packet to be broadcast refers to a broadcast data packet to be transmitted on a BIS link corresponding to a BIG bit, and the BIS link corresponding to the BIG bit is a logical link used by a master bluetooth device to transmit broadcast data to slave bluetooth devices in the BIG bit after creating the BIG bit. The BIS data packet to be broadcasted may be obtained by splitting and encapsulating target broadcast data, where the target broadcast data is broadcast data sent by the master bluetooth device to the slave bluetooth device in the BIG. The target broadcast data may be, for example, audio data. The specific type of data that the target broadcast data is based on depends on the current traffic requirements of the primary bluetooth device for BIG communications.
Specifically, for target broadcast data to be sent to the slave bluetooth device in the BIG, the master bluetooth device may divide the target broadcast data into one or more data segments conforming to the bluetooth communication protocol, so as to implement data packetizing of the target broadcast data; and then according to the Bluetooth communication protocol, respectively encapsulating the one or more data segments obtained by segmentation into protocol data units (protocol data unit, PDU) capable of being transmitted on a Bluetooth channel, thereby obtaining one or more PDUs corresponding to the one or more data segments, and the one or more PDUs obtained by encapsulation can be understood as BIS data packets to be broadcasted. Each PDU has a transmission order that is related to the order of the data segments carried in the PDU in the target broadcast data.
S202, sequentially adopting different signal transmission intensities to send the broadcast synchronous stream data packet to be broadcast to the slave Bluetooth equipment in the broadcast synchronous group.
Specifically, for each BIS data packet to be broadcast, the master bluetooth device may sequentially use different signal transmission intensities to send the BIS data packet to the slave bluetooth device in the BIG, where each broadcast synchronization stream data packet is sent at least m times, where m is the number of signal transmission intensities, and m is greater than 1.
For example, there are 3 BIS data packets to be broadcast currently, P1, P2, and P3, and the signal transmission intensities are TX1, TX2, and … TXm, and for the BIS data packet P1, the BIS data packet P1 is sent with the signal transmission intensity TXi from i being equal to 1 until i is equal to m; for BIS data packet P2, starting from i equal to 1, transmitting BIS data packet P2 by adopting signal transmission intensity TXi until i is equal to m; for BIS data packet P3, sequentially adopting signal transmission intensities TX 1-TXm to transmit BIS data packet P3, and adopting signal transmission intensity TXi to transmit data packet P2 from i equal to 1 until i equal to m.
In the technical scheme corresponding to fig. 2, after obtaining the BIS data packet to be broadcasted, the BIS data packet is broadcasted to the slave bluetooth devices in the BIG by adopting different signal emission intensities in turn, and the BIS data packet is sent to the slave bluetooth devices in the BIG by adopting different signal intensities, so that the slave bluetooth devices in different communication ranges of the master bluetooth device can receive the BIS data packet, thereby improving the reliability of BIG communication; and, adopt different signal strength to send BIS data packet to the slave bluetooth device in BIG, compare with adopting the high-power broadcasting BIS data always, can reduce the equipment consumption.
In the process of sending BIS data packets to be broadcasted to the slave Bluetooth devices in BIG, the master Bluetooth device needs to send the BIS data packets according to BIG information (BIGinfo) of the BIG, and relevant parameters for sending the BIS data packets by the master Bluetooth device are defined in the BIG information.
Referring to fig. 3, fig. 3 is a flow chart of another bluetooth communication method according to an embodiment of the present application, as shown in fig. 3, the method includes the following steps:
s301, acquiring a broadcast synchronous stream data packet to be broadcasted.
S302, acquiring the broadcast synchronization group information of the broadcast synchronization group.
Here, the BIG information of BIG may include link parameters of a BIG link employed by the main bluetooth device to transmit the BIG packet, as shown in fig. 4. The link parameters include specifically the Burst Number (BN). In BIG/BIS communication, BIS packets are transmitted in BIS events, in which one or more BIS packets may be transmitted. BN refers to the number of new BIS packets contained in one BIS event. The link parameters also include the number of sub-events (number of subevents, NSE) contained in the BIS event, NSE being an integer multiple of BN. The sub-event is the minimum transmission unit of the BIS packet, and in each sub-event, the master bluetooth device may transmit a BIS packet to the slave bluetooth device.
After the BIG information of the BIG is obtained, the master Bluetooth device can also send the BIG information to the slave Bluetooth device in the BIG, so that the slave Bluetooth device in the BIG can determine the link parameters of the BIS link adopted by the Bluetooth device to send the BIS data packet.
S303, according to the synchronous group information of the broadcast synchronous group, different signal transmission intensities are adopted in sequence, and broadcast synchronous stream data packets to be broadcast are sent to the slave Bluetooth equipment in the broadcast synchronous group.
Specifically, the broadcast synchronization stream data packet to be broadcast may be transmitted to the slave bluetooth device in the broadcast synchronization group by the following steps A1-A2:
a1, acquiring target quantity.
Here, the target number is the number of signal transmission intensities, that is, how many signal transmission intensities the master bluetooth device uses to transmit the BIS packet for the same BIS packet, and the target number is m.
In this application, the target number may be obtained in various manners, and some specific cases of obtaining the target number are described below.
In the first case, the target number is preset by the user and stored in the master bluetooth device.
In this case, the target number is a fixed value, and the target number can be acquired locally from the device.
In the second case, the target number may be determined based on BIG information of BIG.
Specifically, the target number may be determined according to the number of sub-events and the number of bursts in the BIG information of the BIG, where the product of the target number and the number of bursts is less than or equal to the number of sub-events, and the target number may be any positive integer greater than 1 and less than the ratio of the number of sub-events to the number of bursts.
For example, BN in BIG information is 1, nse is 4, the ratio of nse to BN is 4, then m may be 2 or 3 or 4; as another example, if BN in BIG information is 2, nse is 6, and the ratio of nse to BN is 3, then m may be 2 or 3.
The number of signal transmission intensities is determined according to the number of sub-events and the number of bursts in the BIG information, so that the number of signal transmission intensities can meet the parameter setting of BIG communication.
In a third case, the target number may be determined according to the communication requirements of the BIG.
In one possible implementation, the target number may be determined based on the quality of service required for BIG communications. The target quantity and the service quality required by BIG can meet the positive correlation relation, namely, the higher the service quality required by BIG communication is, the larger the target quantity is; the lower the quality of service required for BIG communication, the smaller the target number.
In another possible implementation manner, the target number may also be determined according to the priority of the broadcast service corresponding to the BIG. The priority of the broadcasting service corresponding to the BIG can meet the positive correlation relation, namely, the higher the priority of the broadcasting service corresponding to the BIG is, the larger the target number is; the lower the priority of the broadcasting service corresponding to the BIG, the smaller the target number.
The determination of the target number according to the communication requirements of the BIG may not be limited to the above-described embodiment, and the present application is not limited thereto. The number of signal emission intensities is determined according to the communication requirement of BIG, so that the number of signal emission intensities is more reasonable and effective, and the reliability of BIG communication is better ensured.
Fourth, the target number is determined according to BIG information of BIG and BIG communication requirements.
In this case, a target number range may be determined according to the number of sub-events and the number of bursts in the BIG information of the BIG, where the target number range is a number range of signal emission intensities; and determining the target quantity from the target quantity range according to BIG communication requirements. Or, the first quantity range can be determined according to the BIG information of the BIG, and the second quantity range can be determined according to the communication requirement of the BIG, wherein the first quantity range and the second quantity range are both quantity ranges of signal emission intensity; an intersection of the first number of ranges and the second number of ranges is then determined as the target number.
In some possible cases (e.g., the target number is obtained based on the first case and the third case), if the product of the obtained target number and the burst number is greater than the sub-event number, the target number may be modified after the obtained target number is obtained so that the product of the target number and the burst number is less than the sub-event number. Alternatively, the BN or NSE in the BIG information may be modified after the target number is acquired so that the product of the target number and the burst number is smaller than the number of sub-events. When the number of signal transmission intensities is not matched with the number of bursts and the number of sub-events in the BIG, the number of signal transmission intensities can be enabled to meet the parameter setting of BIG communication by modifying the number of bursts or the number of sub-events or the target number in BIG information.
After the target number is obtained, m signal transmission intensities can be determined according to the target number and the signal transmission intensity range of the master bluetooth device.
In a specific implementation manner, m signal emission intensities can be determined based on an equal division idea, and each signal emission intensity is obtained by dividing a signal emission range by m.
For example, where m is 4 and the range of signal transmission strengths of the master Bluetooth device is 0+ -20 dbm, the 4 signal transmission strengths are 0dbm, 5dbm, 10dbm, and 20dbm.
Or, M signal emission intensities may be preset, where M is greater than M and the signal emission range is obtained by dividing M by M, where M is selected randomly from the M signal emission intensities, or the M signal intensities that are the largest/smallest of the M signal emission intensities are selected.
The present application is not limited to how the m signal emission intensities are determined in particular.
And A2, sequentially adopting m signal transmission intensities, and transmitting N broadcast synchronous stream data packets with continuous sequence numbers to the slave Bluetooth equipment in the BIG.
For example, using m signal transmission intensities in turn, sending N broadcast synchronous stream packets with consecutive sequence numbers to the BIG from the bluetooth device may be as shown in fig. 5.
In the above technical solution of fig. 3, after obtaining the BIS data packet to be broadcasted, the BIG information of the BIG is obtained first, and then, according to the BIG information of the BIG, different signal transmission intensities are sequentially adopted to send the broadcast synchronous stream data packet to be broadcasted to the slave bluetooth device in the broadcast synchronous group, so that the transmission of the BIS data packet can conform to the link parameters of the BIG.
The method of the present application is described above and the apparatus of the present application is described below.
