Detailed ways

For ease of understanding, some related concepts involved in this application are introduced first.

As a wireless communication technology, Bluetooth is used to transmit data such as audio information, file information and broadcast information across devices, and can realize short-distance data exchange between different devices. BLE technology is a new generation of Bluetooth communication technology. This technology has the characteristics of low energy consumption and low delay, so it is widely used in various scenarios that require short-distance communication.

BLE technology supports broadcasting scenarios. In a broadcast scenario, a broadcast sender can broadcast data, and the broadcast data can be simultaneously received by multiple broadcast receivers (also called synchronous receivers or broadcast synchronizers).

The present application does not limit broadcast data, and the broadcast data may be audio data, video data, or text data. For example, in BLE Audio (BLE Audio) technology, multiple broadcast receivers can simultaneously receive audio data (such as music and/or voice) sent by the broadcast sender. Or, in virtual reality (virtual reality, VR) technology or augmented reality (augmented reality, AR) technology, multiple broadcast receivers can simultaneously receive video data (such as virtual images) and/or audio data sent by the broadcast sender.

Both the broadcast sender and the broadcast receiver are devices or devices that support Bluetooth communication. For example, either the broadcast sender or the broadcast receiver can be one of the following devices: mobile phone, tablet computer, notebook computer, palmtop computer, personal digital assistant (personal digital assistant, PDA), portable media player (portable media player) , PMP), digital TV, desktop computer, Bluetooth headset, Bluetooth audio and other electronic equipment.

Bluetooth broadcasting can be widely used in game rooms, cinemas, conference rooms, classrooms, airports and other scenarios.

Take the game room scene as an example, where players can play a video game in the same room. The game terminal can be used as a broadcast sender, and multiple Bluetooth headsets can be used as broadcast receivers. The game terminal can synchronously send game sounds to multiple Bluetooth headsets through Bluetooth broadcasting. Players can receive the game sound by wearing a Bluetooth headset, so as to achieve the effect of multiple players participating in the game at the same time.

Take the conference room scenario as an example. In a conference room, the Bluetooth headset collects and transmits the voice of the speaker. In order to achieve a good playback effect, multiple Bluetooth speakers can be set up in different positions in the meeting room. For this scenario, the Bluetooth headset can be used as the broadcast sender, and multiple Bluetooth speakers can be used as the broadcast receiver. The Bluetooth headset can send speech voices to multiple Bluetooth speakers synchronously through Bluetooth broadcasting, so that audiences at various positions in the conference room can listen to the speech content and achieve good listening effects.

In the Bluetooth specification (or protocol), BIS is a broadcast synchronization stream, and BIG is a broadcast synchronization group. BIG is a collection of multiple BIS. For example, one BIG can include 31 BIS.

Broadcast senders can configure BIG/BIS. For example, the broadcast sender can configure at least one of the following parameters: the number of BISs in the BIG; the index of the BIS; the time interval between corresponding sub-events (events) in two adjacent BISs in the BIG; The time interval between two consecutive sub-events; the maximum number of data bytes that can be carried by the protocol data unit (PDU) of each BIS in the BIG; and whether the data in the BIG is encrypted.

Multiple broadcast receivers receive data in BIS by synchronizing to BIG/BIS.

In the following, in combination with FIG. 1 , taking one broadcast sender corresponding to three broadcast receivers as an example, the synchronization process of BIG/BIS will be described as an example.

In step S110, the broadcast sender starts periodic advertising (PA).

Step S120, the broadcast sender starts BIG. The BIG may include one or more BISs. The BIG/BIS can be carried in periodic broadcast.

Step S130, the broadcast sender enables the transmission path. The transmission path is the transmission path corresponding to the BIS that the broadcast sender needs to send. This transmission path can be used to transmit audio data. Therefore, in some embodiments, this transmission path may also be referred to as an audio transmission path (audio data path).

From step S141 to step S143, broadcast receiver 1, broadcast receiver 2 and broadcast receiver 3 respectively scan and synchronize to BIG/BIS. For example, broadcast receivers can first sync to Bluetooth periodic broadcasts. Broadcast receivers can then resynchronize to BIG/BIS via periodic broadcasts. Alternatively, broadcast receivers can sync to the Bluetooth periodic broadcast as well as BIG/BIS at the same time.

After the above process, BIG/BIS is completed synchronously. Next, it can enter the streaming data sending state, that is, the broadcast sender can use the BIS in the BIG to send data to the broadcast receiver, see steps S151-S153 in FIG. 1 .

Each BIS in the BIG can be used to deliver the corresponding audio stream. For example, one BIS may correspond to one audio channel, and in order to support multiple audio channels, one BIS may include two BISs. Broadcast senders can use two BISs to transmit the left and right channels of audio, respectively. Alternatively, a BIG can include 5 BIS, thus supporting 5.1 surround sound channels. Alternatively, one BIG may include multiple BISs, and the multiple BISs may carry voices in different national languages, so as to provide simultaneous transmission of multilingual voices for users of different nationalities. Therefore, BIG/BIS can provide a new experience for Bluetooth users.

FIG. 2 shows a scenario where the broadcast sender is a master device (master) 210 and the broadcast synchronization receivers are two slave devices (slave) 220 . Taking FIG. 2 as an example, the BIG in FIG. 2 may include BIS1 and BIS2. BIS1 and BIS2 can be used to transmit the left and right channels of audio respectively. Two slave devices 220 can be synchronized to the BIG to simultaneously receive audio streams in BIS1 and BIS2. On the one hand, based on BIG/BIS, one-to-two audio transmission can be realized; on the other hand, the slave device 220 receives audio data of two channels, which enables users using the slave device 220 to obtain a richer audio experience.

It can be seen from the above content that the broadcast sender can send data to multiple broadcast receivers through BIG/BIS. Broadcast receivers usually only receive data through BIS. However, in some cases, broadcast receivers may wish to send data to broadcast senders or other broadcast receivers. In view of this situation, the prior art needs to establish a new BLE connection between the broadcast receiver and the broadcast sender or between the broadcast receiver and other broadcast receivers.

In order to support the broadcast receiver to send data, one possible implementation is to establish a new BLE connection between the broadcast receiver and other broadcast receivers or between the broadcast sender and the broadcast receiver respectively, another possible implementation It is the broadcast receiver that establishes a new BLE connection with the broadcast sender. Through the BLE connection, the broadcast receiver can send data to the broadcast sender, and the broadcast sender broadcasts the data. However, both of the above two methods have many disadvantages. Combining with the game scene shown in FIG. 3 , the problems existing in these two methods are analyzed below.

As shown in Fig. 3, a plurality of players (Fig. 3 takes 5 players as an example) are sitting in the same room and playing a competitive game. 325 is synchronized to the game terminal 310 to listen to the game sound. If local game communication is required between players, voice data needs to be exchanged between the Bluetooth headsets 321-325. Taking the exchange of voice data between the Bluetooth earphone 321 and other Bluetooth earphones as an example, the exchange of voice data between the Bluetooth earphones can be realized in two ways: method 1 and method 2.

Method 1: The Bluetooth headset 321 establishes a BLE connection 332 with the game terminal 310 , and sends voice data to the game terminal 310 through the BLE connection 332 . Afterwards, the game terminal 310 sends out the voice data through the Bluetooth broadcast audio 331 for other players to listen to.

Method 2: The Bluetooth headset 321 establishes BLE connections 333-336 with the Bluetooth headsets 322-325 respectively. BLE connections 333-336 can be used to exchange voice data.

For method one, the Bluetooth headset 321 sends the voice data to the game terminal 310 through the BLE connection 332 , and forwards it through the game terminal 310 . This way will increase the transmission delay of the voice data, and the Bluetooth headset 321 will also receive the voice from itself.

For the second method, if there are many game players, the overhead of establishing Bluetooth BLE connections between Bluetooth headsets will be very high. Moreover, maintaining multiple BLE connections requires a high degree of scheduling. In addition, this method will cause waste of power consumption and bandwidth as a whole.

It can be seen from the above that for the situation where the broadcast receiver needs to send data, if the above-mentioned method 1 and method 2 are adopted, there will be many problems such as waste of power consumption and bandwidth, increased delay or poor user experience. Therefore, a more rational solution is required.

The embodiments of the present application are described below by referring to FIG. 4 to FIG. 8 , so as to solve the above problems.

Embodiment one

FIG. 4 is a schematic flowchart of a communication method proposed in an embodiment of the present application. The method in FIG. 4 is executed by the broadcast sender and the first broadcast receiver. The first broadcast receiver may be any one of multiple broadcast receivers.

Step S410, the broadcast sender configures BIG. The BIG includes a first BIS, and the first BIS corresponds to a first transmission path, and the first transmission path is a transmission path for sending data from a first broadcast receiver to a broadcast sender and/or other broadcast receivers.

The BIG may include one or more BISs, which is not limited in this application. When the BIG includes multiple BISs, the first BIS is any one of the multiple BISs.

Multiple BISs in the BIG may be sent by the broadcast sender or by the first broadcast receiver. For example a BIG may include a second BIS sent by the broadcast sender. If there are multiple broadcast receivers, the BIS to send can be configured for these broadcast receivers respectively.

The first broadcast receiver may only send the first BIS, or may send multiple BISs. For the case where the first broadcast receiver sends multiple BISs, the multiple BISs can be used to deliver corresponding data streams of the first broadcast receiver respectively. For example, the first broadcast receiver may send two BIS, which are respectively used to transmit the left channel and the right channel of the first broadcast receiver's audio.

Step S420, the first broadcast receiver enables the first transmission path corresponding to the first BIS.

It can be understood that there may be multiple BIS sent by the first broadcast receiver. In this case, the first broadcast receiver needs to respectively enable transmission paths corresponding to multiple BISs.

For other Bluetooth devices (including other broadcast receivers and broadcast senders) synchronized to the first BIS, the data sent by the first broadcast receiver can be received based on the first transmission path.

Step S430, the first broadcast receiver sends data based on the first transmission path. Based on the first transmission path, the first broadcast receiver can send data to the broadcast sender, and can also send data to other broadcast receivers of the broadcast sender. That is to say, the first broadcast receiver can broadcast data through the method provided in this application.

This application configures the BIG through the broadcast sender, and configures the first BIS in the BIG to be sent by the broadcast receiver. The first broadcast receiver can use the first BIS to send data to the broadcast sender or other broadcast receivers, thereby avoiding the establishment of a new broadcast between the first broadcast receiver and the broadcast sender or between the broadcast receiver and other broadcast receivers. BLE connection, which reduces power consumption and saves bandwidth.

For the case where multiple BIS are included in the BIG configured by the broadcast sender, different BIS of the BIG can be transmitted by different devices, the first broadcast receiver can send at least one BIS including the first BIS, and other broadcast receivers or broadcast senders Or can send other BIS in BIG separately. This not only meets the broadcast sender's need to send data, but also realizes "distributed broadcast" sending.

Optionally, before step S410, the method described in this application may further include step S405.

Step S405, establishing a connection between the broadcast sender and the first broadcast receiver. The connection realizes information interaction between the broadcast sender and the first broadcast receiver, so that the configured BIG information can be sent to the first broadcast receiver.

The connection between the broadcast sender and the first broadcast receiver may be a direct connection or an indirect connection. That is to say, the broadcast sender and the first broadcast receiver can be connected through at least one other device.

The application does not limit the connection type, for example, the connection type may be a BLE connection, a Bluetooth broadcast connection or other non-Bluetooth connections.

After the BIG configuration is completed, the connection can be disconnected to avoid resource waste.

It can be understood that, in addition to establishing a new connection, the exchange of information related to BIG configuration between the broadcast sender and the first broadcast receiver can also be realized based on the existing connection between the broadcast sender and the first broadcast receiver.

Embodiment two

FIG. 5 is a schematic flowchart of another communication method proposed by the embodiment of the present application. The method in FIG. 5 is executed by the broadcast sender and the first broadcast receiver.

Step S510, the broadcast sender configures BIG. BIG includes the first BIS. The first BIS corresponds to the first transmission path, and the first transmission path is used for the first broadcast receiver to send data to the broadcast sender and/or other broadcast receivers. For the relevant description of step S510, reference may be made to step S410 in Embodiment 1, which will not be repeated in this application.

In step S580, the first broadcast receiver enables the first transmission path corresponding to the first BIS.

In step S590, both the broadcast sender and the first broadcast receiver enter a streaming data sending state. In the streaming data sending state, both the broadcast sender and the first broadcast receiver can become data senders and broadcast. The broadcast sender may send data to the first broadcast receiver or other broadcast receivers. The first broadcast receiver may send data to the broadcast sender or other broadcast receivers based on the first transmission path.

Except step S510, step S580 and step 590. The communication method proposed in this application may further include one or more of steps S520 to S570.

Step S520, the first broadcast receiver synchronizes to the first BIS.

Optionally, the first broadcast receiver can be synchronized to other BISs in the BIG except the first BIS, so that data can be received or sent synchronously through other BISs.

In step S530, the broadcast sender sends query information to the first broadcast receiver, and the query message is used to query whether the first broadcast receiver supports a framed mode or an unframed mode.

For the unframed mode, the data transmission of the upper layer and the lower layer is synchronous, and complete data can be transmitted. For the framed mode, the data transmission of the upper layer and the lower layer is not synchronous, and the transmitted data needs to be segmented. Obviously, the unframed mode has high requirements on the system, and not all devices can support the unframed mode.

When configuring the BIG, it needs to be configured whether it supports the unframed mode or the framed mode, which can be determined according to the capability of the first broadcast receiver. Therefore, the broadcast sender can determine the mode in which the BIG is configured by querying whether the first broadcast receiver supports the unframed mode or the framed mode. For example, when the first broadcast receiver supports the unframed mode, the broadcast sender can configure the BIG as the unframed mode; when the first broadcast receiver supports the framed mode, the broadcast sender can configure the BIG as the framed mode. Or, when there are multiple broadcast receivers, only when all the broadcast receivers support the unframed mode, the broadcast sender can configure the BIG as the unframed mode; otherwise, the broadcast sender can configure the BIG as the framed mode.

This application does not limit the manner in which the broadcast sender queries the unframed mode or the framed mode of the first broadcast receiver. For example, the broadcast sender may send a query message to the first broadcast receiver, and after receiving the query message, the first broadcast receiver sends a message to the broadcast sender that the first broadcast receiver supports unframed mode or framed mode.

In step S540, the broadcast sender sends configuration information to the first broadcast receiver. The configuration information may be used to configure the first BIS. The broadcast sender may instruct the first broadcast receiver to send the first BIS by sending configuration information. The broadcast sender may send the first BIS in step S590.

This application does not limit the way the broadcast sender sends the configuration information. For example, the broadcast sender may establish a BLE connection with the first broadcast receiver, and send configuration information through the BLE connection. Alternatively, the broadcast sender may also establish a broadcast connection with the first broadcast receiver, and send configuration information through broadcast.

The broadcast sender may directly send configuration information to the first broadcast receiver, or may indirectly send configuration information to the first broadcast receiver. For example, the broadcast sender may first send configuration information to a device that has established a connection with the first broadcast receiver, and the configuration information is sent to the first broadcast receiver through the device.

After receiving the configuration information sent by the broadcast sender, the first broadcast receiver may feedback and confirm to the broadcast sender.

The broadcast sender may also indicate the BIS received by the first broadcast receiver through configuration information. The first broadcast receiver may receive the BIS received by the first broadcast receiver in subsequent steps. For example, the BIS received by the first broadcast receiver may be at least one BIS in the BIG except the first BIS. Since the first BIS is the BIS sent by the first broadcast receiver, the broadcast sender will also receive the data sent by itself after receiving the first BIS, which will cause data redundancy. Therefore, without receiving the first BIS, the broadcast sender will not receive the data sent by itself. Take the game scene shown in Figure 3 as an example, if the first broadcast receiver does not receive the first BIS, or the first broadcast receiver does not use the first BIS after receiving the first BIS, then the broadcast sender will not listen The voice message sent by myself has arrived. Alternatively, the BIS received by the first broadcast receiver may be configured as required. For example, the first broadcast receiver can receive all BIS in BIG except the first BIS, then the first broadcast receiver can not only receive the data sent by the broadcast sender, but also receive the data sent by all other broadcast receivers . Taking the game scene shown in Figure 3, the Bluetooth headset 321 is the first broadcast receiver as an example, the Bluetooth headset 321 can receive all BIS except the first BIS in the BIG configured by the game terminal 310, and then receive the game terminal 310 and other Bluetooth broadcast receivers. Voice information sent by earphones 322-325.

The configuration information may include an index of a BIS transmitted by the first broadcast receiver and/or an index of a received BIS. The index of the BIS transmitted by the first broadcast receiver may include the index of the first BIS. Or, when the first broadcast receiver sends multiple BISs, the index of the BIS sent by the first broadcast receiver may also include the indices of other multiple BISs. For example, if the index of the second BIS sent by the broadcast sender is 1 and the index of the first BIS is 2, the index of the BIS sent by the first broadcast receiver can be 2, and the index of the BIS received by the first broadcast receiver Can be 1.

In step S550, the broadcast sender starts periodic broadcasting.

Step S560, the broadcast sender starts BIG.

Step S570, the broadcast sender enables the corresponding transmission path for the second BIS.

It can be seen from the above that BIG/BIS is carried by Bluetooth periodic broadcast, therefore, before starting BIG, the broadcast sender needs to start periodic broadcast. After the broadcast sender starts BIG, the first broadcast receiver can scan and synchronize to BIG/BIS. Broadcast receivers can synchronize to periodic broadcast first, and then synchronize to BIG/BIS, or synchronize to periodic broadcast and BIG/BIS at the same time.

The second BIS is any BIS in the BIG configured by the broadcast sender, and the second BIS is different from the first BIS.

The broadcast sender can enable the corresponding second transmission path for the second BIS, then in step S590, the broadcast sender can send the data of the broadcast sender to the first broadcast receiver and/or other broadcast receivers through the second transmission path .

It can be understood that there may be multiple BISs sent by the broadcast sender. In this case, the broadcast sender needs to enable the transmission paths corresponding to multiple BISs respectively.

Embodiment Three

FIG. 6 is a schematic flowchart of another communication method proposed by the embodiment of the present application. The method in FIG. 6 may be executed by the broadcast sender and three broadcast receivers, and the first broadcast receiver may be any one of broadcast receiver 1 , broadcast receiver 2 , and broadcast receiver 3 .

From step S611 to step S613, the broadcast sender establishes BLE connections with broadcast receiver 1, broadcast receiver 2, and broadcast receiver 3 respectively.

In steps S621 to S623, the broadcast sender sends the first query message, the second query message, and the third query message to broadcast receiver 1, broadcast receiver 2, and broadcast receiver 3 respectively, so as to obtain broadcast receiver 1, broadcast Receiver 2 and Broadcast Receiver 3 support framed mode or unframed mode.

In steps S631 to S633, the broadcast sender sends the first configuration information, the second configuration information and the third configuration information to the broadcast receiver 1, the broadcast receiver 2 and the broadcast receiver 3 respectively, so as to configure the BIG.

The first configuration information includes the index of BIS sent and received by broadcast receiver 1; the second configuration information includes the index of BIS sent and received by broadcast receiver 2; the third configuration information includes the index of BIS sent and received by broadcast receiver 3 index of the BIS.

Optionally, the indexes of the BIS sent and received by the broadcast sender, broadcast receiver 1 , broadcast receiver 2 and broadcast receiver 3 are shown in Table 1.

Table 1

设备equipment	发送的BIS索引BIS index sent	接收的BIS索引Received BIS index
广播发送者broadcast sender	11	无none
广播接收者1broadcast receiver 1	22	1/3/41/3/4
广播接收者2broadcast receiver 2	33	1/2/41/2/4
广播接收者3broadcast receiver 3	44	1/2/31/2/3

Regarding the situation shown in Table 1, FIG. 7 shows the situation that the broadcast sender, broadcast receiver 1, broadcast receiver 2 and broadcast receiver 3 receive and send BIS. A broadcast sender only sends data and does not receive any data. Broadcast receiver 1, broadcast receiver 2, and broadcast receiver 3 not only send data, but also receive all data sent by themselves. It can be seen from Table 1 and FIG. 7 that the situation shown in Table 1 is suitable for a game scene similar to that in FIG. 3 , where the game scene may include 3 players. As shown in Figure 8, the three players can not only receive audio data from the game terminal, but also transmit voice data to each other during the game, realizing the function of chatting synchronously during the game.

In step S640, the broadcast sender starts periodic broadcasting.

Step S650, the broadcast sender starts the BIG

In step S660, the broadcast sender enables a voice data transmission path for the target BIS (the BIS sent by the broadcast sender).

From step S671 to step S673, broadcast receiver 1, broadcast receiver 2 and broadcast receiver 3 respectively scan and synchronize to BIG/BIS.

In steps S681 to S683, the broadcast receivers respectively enable data transmission paths for the target BIS (the BIS that needs to be sent). Taking the situation shown in Table 1 as an example, broadcast receiver 1 enables the voice data transmission path for BIS2; broadcast receiver 2 enables the voice data transmission path for BIS3; broadcast receiver 3 enables the voice data transmission path for BIS4.

Based on the above steps, the configuration and synchronization of BIG is completed.

In step S690, the broadcast sender, broadcast receiver 1, broadcast receiver 2, and broadcast receiver 3 all enter the streaming data sending state, and can send data.
