Wherein bluetooth module 250 supports bluetooth functionality. The bluetooth technology is a radio technology supporting short-distance communication of devices, and can perform wireless information interaction among various wireless terminal devices including smart phones, personal computers, notebook computers, tablet computers, portable wearable devices, wireless earphones, wireless sound boxes and the like.

Fig. 3 is a flow diagram of a method for a bluetooth device to control transmissions in one embodiment. The method for controlling transmission by the bluetooth device shown in fig. 3 can be applied to the bluetooth device 102, and includes:

step 202, physical connections are established with the first terminal and the second terminal respectively.

Specifically, the bluetooth device may establish a physical connection, i.e., an ACL (asynchronous connection) connection, with the first terminal and the second terminal at the same time. ACL links are directed transmission packets that support both symmetric and asymmetric connections. The established physical connection comprises connection of an upper layer protocol HFP (hand-Free Profile) and connection of an upper layer protocol A2DP (Advanced Audio Distribution Profile, bluetooth Audio transmission model protocol), wherein the HFP protocol specifies that a Hands-Free device controls related operations of the telephone, and the Hands-Free device refers to related bluetooth devices, such as vehicle-mounted bluetooth, bluetooth sound box and the like. A2DP defines protocols and procedures for transmitting high quality audio information, such as mono or stereo, over ACL channels.

Step 204, when the first service data transmission is being performed with the first terminal, receiving a second service data transmission request sent by the second terminal.

The first service may be a call service, where the call service refers to a bluetooth call protocol, that is, a service corresponding to an HFP protocol, such as making a call through a phone number, performing a real-time voice call in an application, performing a video call in the application, and the like. The first service may also be an audio service, where the audio service refers to a service corresponding to a bluetooth audio protocol, that is, a service corresponding to an A2dp protocol, such as playing music or video. The first service may also be other multimedia services.

Specifically, the first terminal sends a service notification to the bluetooth device through the corresponding physical connection, when the bluetooth device is idle, the service notification is replied to the first terminal, and first service data transmission is performed according to a first service type corresponding to the first terminal. And if the first service is a call service, the Bluetooth device and the first terminal establish an SCO link, and the Bluetooth device and the first terminal perform service data transmission through the SCO link. SCO (Synchronous Connection organized) is mainly used to transmit data communication with high time requirement, and is usually used in bluetooth call or virtual phone scenario. And if the first service is the audio service, receiving the audio data stream of the first terminal and outputting the audio service data of the first terminal. The second service data transmission request is used for requesting second service data transmission with the bluetooth device, and indicates that the second terminal needs to seize the bluetooth device with the first terminal. The second service data transmission request is used for requesting to transmit second service data with the bluetooth device, wherein the second service may be a call service, an audio service, or other multimedia services.

In one embodiment, the receiving the second service data transmission request sent by the second terminal includes: and when the second service is a service corresponding to the Bluetooth communication protocol, receiving a communication connection instruction sent by the second terminal. And when the second service is a service corresponding to the Bluetooth audio protocol, receiving an audio data playing request sent by the second terminal.

Specifically, the second service data transmission request has different forms when the second terminal performs different services, if the second terminal performs a call service, which is a service corresponding to the bluetooth call protocol, a call connection instruction is generated when the second terminal connects the call request, and the call connection instruction is sent to the bluetooth device, where the bluetooth device receives the call connection instruction, that is, the call connection instruction is the received second service data transmission request. If the second terminal carries out the audio service which is the service corresponding to the Bluetooth audio protocol, when the second terminal needs to play audio data, an audio data playing request is generated and sent to the Bluetooth equipment, and the Bluetooth equipment receives the audio data playing request, namely, the audio data playing request is received. The audio data playing request may be generated when the audio player is started to play the audio data for the first time, or may be generated when the audio data is played again after the audio data is paused. Different services correspond to different service data transmission requests, and the Bluetooth equipment performs corresponding responses after recognizing the service data transmission requests corresponding to the different services.

Step 206, determining a target data transmission terminal according to the priority of the first service and the second service, controlling the link data reception corresponding to the non-target data transmission terminal according to the service type corresponding to the non-target data transmission terminal, maintaining the physical connection with the non-target data transmission terminal, and controlling the link data reception corresponding to the non-target data transmission terminal includes reducing the received data frequency of the corresponding link to the target frequency or disconnecting the corresponding SCO synchronous connection-oriented link.

The target data transmission terminal is a terminal which finally successfully seizes the Bluetooth equipment and normally communicates with the Bluetooth equipment, the target data transmission terminal and the non-target data transmission terminal are respectively determined from the first terminal and the second terminal according to the priority of the first service and the second service, the terminal with high service priority level is used as the target data transmission terminal, and the terminal with low service priority level is used as the non-target data transmission terminal. The priority between different services can be customized according to requirements, and in one embodiment, the priority of the call service is higher than that of the audio service. It can be understood that, if the first service and the second service are services with the same priority level, the corresponding target data transmission terminal is determined according to the sequence of the service data transmission requests, and a specific rule may be defined. In one embodiment, when the service priority levels are the same, the terminal that later sends the service data transmission request serves as a target data transmission terminal, and can preempt the service resources that are being transmitted before. The terminal corresponding to the service with high priority level can preempt the use of the Bluetooth equipment by the terminal corresponding to the service with low priority level.

Specifically, the receiving of the link data corresponding to the non-target data transmission terminal is controlled according to the service type corresponding to the non-target data transmission terminal, and when the service types corresponding to the non-target data transmission terminals are different, the receiving of the link data corresponding to the non-target data transmission terminals is controlled to be different. The control mode comprises reducing the received data frequency of the corresponding link to the target frequency or disconnecting the corresponding SCO synchronous connection-oriented link, wherein the target frequency can be customized according to needs and the received data frequency is reduced, so that the occupation of the link on the bandwidth of the Bluetooth equipment is reduced, and the service between the target data transmission terminal and the Bluetooth equipment is not influenced. Even if the application data of the first terminal is still transmitted to the Bluetooth device through physical connection after switching, the Bluetooth device discards the service data transmitted by the first terminal, so that the sound of the third-party application app during and after switching cannot be played, and the user cannot be troubled by playing the sound. After the switching, the physical connection with the non-target data transmission terminal is kept, so that the reconnection is not needed in the next switching, and the switching efficiency is improved. And the audio data of the non-target data transmission terminal is not played. And (3) disconnecting the corresponding SCO synchronous connection-oriented link, so that the call data of the non-target data transmission terminal cannot be transmitted to the Bluetooth equipment, and the service data of the non-target data transmission terminal can be directly output from a microphone of the non-target data transmission terminal.

And step 208, performing service data transmission with the target data transmission terminal.

Specifically, according to the service type corresponding to the target data transmission terminal, a matching mode is selected to perform service data transmission with the target data transmission terminal. If the data is a call service, an SCO link needs to be established with the target data transmission terminal, and service data transmission is performed with the target data transmission terminal through the SCO link. And if the data is the audio service, receiving the audio data stream of the target data transmission terminal and outputting the audio service data of the target data transmission terminal.

In the method for controlling transmission by a bluetooth device in this embodiment, the bluetooth device establishes physical connections with a first terminal and a second terminal, respectively; receiving a second service data transmission request sent by a second terminal when the first service data transmission is carried out with a first terminal; determining a target data transmission terminal according to the priority of a first service and a second service, controlling the receiving of link data corresponding to the non-target data transmission terminal according to the service type corresponding to the non-target data transmission terminal, and keeping the physical connection with the non-target data transmission terminal, wherein the controlling of the receiving of the link data corresponding to the non-target data transmission terminal comprises reducing the receiving data frequency of a corresponding link to a target frequency or disconnecting a corresponding SCO synchronous connection-oriented link; when the Bluetooth device supports one-to-two operation, the Bluetooth device can be automatically switched to use according to the service priority of two terminals connected with the Bluetooth device, the physical connection between the two terminals and the Bluetooth device does not need to be disconnected and reconnected during switching, so that the switching speed is improved, the switching delay between the devices is low, when the two devices switch to use the Bluetooth device, the two devices still keep the physical connection with the Bluetooth device, the interaction frequency of an ACL link established with a non-target data transmission terminal is reduced, so that the occupation of the bandwidth of the Bluetooth device by the link is reduced, the service between the target data transmission terminal and the Bluetooth device is not influenced, or a corresponding SCO synchronous connection-oriented link is disconnected, the call data of the non-target data transmission terminal cannot be transmitted to the Bluetooth device, the occupation of the bandwidth of the Bluetooth device by the link is avoided, the service between the target data transmission terminal and the Bluetooth device is not influenced, and the efficiency and the quality of data transmission are improved.

In one embodiment, the step 206 of determining the target data transmission terminal according to the priority of the first service and the second service comprises: and when the priorities of the first service and the second service are the same, determining that the second terminal is a target data transmission terminal and the first terminal is a non-target data transmission terminal. And when the priority of the first service is higher than that of the second service, determining that the first terminal is a target data transmission terminal and the second terminal is a non-target data transmission terminal. And when the priority of the first service is lower than that of the second service, determining that the second terminal is a target data transmission terminal and the first terminal is a non-target data transmission terminal.

Specifically, when the priorities of the first service and the second service are the same, the second terminal sends a service data transmission request, so that the ongoing first service data transmission can be preempted, and the second terminal is determined to be the target data transmission terminal.

If the first terminal is using the Bluetooth device to perform the call service, the second terminal generates the call service, if the user answers the call service of the second terminal, the second terminal sends a call service data transmission request to the Bluetooth device, and because the priorities of the first service and the second service are the same, the second terminal is determined to be a target data transmission terminal and the first terminal is a non-target data transmission terminal, so that the connection switching between the Bluetooth device and the terminal is realized, the physical connection with the first terminal is maintained, the SCO synchronous connection-oriented link corresponding to the first terminal is disconnected, and the service data transmission with the second terminal is started.

If the first terminal is using the Bluetooth device to perform audio service, and the second terminal generates audio service, the second terminal sends an audio service data transmission request to the Bluetooth device, and because the priority of the first service is the same as that of the second service, the second terminal is determined to be a target data transmission terminal, and the first terminal is a non-target data transmission terminal, so that the connection switching between the Bluetooth device and the terminal is realized, the physical connection with the first terminal is maintained, the received data frequency of a link corresponding to the first terminal is reduced to the target frequency, and the service data transmission with the second terminal is started.

If the first terminal is using the Bluetooth device to perform the call service, the second terminal generates the audio service, and because the call service optimization level is higher than the audio service, the first terminal is determined to be the target data transmission terminal and the second terminal is the non-target data transmission terminal, so the Bluetooth device maintains the call service of the first terminal, maintains the physical connection with the second terminal, and simultaneously reduces the received data frequency of the link corresponding to the second terminal to the target frequency.

If the first terminal is using the Bluetooth device to perform the audio service, the second terminal generates the call service, and because the call service optimization level is higher than the audio service, the second terminal is determined to be a target data transmission terminal, the first terminal is a non-target data transmission terminal, the connection switching between the Bluetooth device and the terminals is realized, the physical connection with the first terminal is maintained, the received data frequency of the link corresponding to the first terminal is reduced to the target frequency, and the service data transmission with the second terminal is started. After the second terminal seizes the Bluetooth equipment, the audio service of the first terminal can not be snatched back to the Bluetooth equipment in the conversation process because the conversation service priority is higher than the audio service.

The audio service is a service corresponding to a Bluetooth audio protocol, and the call service is a service corresponding to a Bluetooth call protocol.

In the embodiment, the target data transmission terminal and the non-target data transmission terminal are determined in a self-adaptive manner according to the priority of the first service and the priority of the second service, so that automatic switching can be realized subsequently, and convenience and high efficiency are realized. The user can define the priority level of each different service, thereby flexibly realizing the switching between the Bluetooth equipment and the terminal service transmission.

In one embodiment, the first service and the second service are services corresponding to a bluetooth call protocol, and step 206 includes: and if the priority of the first service is the same as that of the second service, the second terminal is a target data transmission terminal, the first terminal is a non-target data transmission terminal, and the SCO link with the first terminal is disconnected. Step 208 includes: and creating an SCO link with the second terminal, and transmitting service data with the second terminal through the SCO link.

Specifically, the first service and the second service are services corresponding to a bluetooth call protocol, and the priorities of the first service and the second service are the same, the second terminal is a target data transmission terminal, and the first terminal is a non-target data transmission terminal. The bluetooth device will disconnect the SCO link with the first terminal, let the service data of first terminal directly export from the terminal microphone, keep being connected with the physics of first terminal simultaneously, including upper protocol HFP's connection, if the first terminal supports the service that the bluetooth audio protocol corresponds, then can also keep the connection of upper protocol A2DP, the bluetooth device will establish the SCO link with the second terminal, the conversation sound of second terminal will be exported from the bluetooth device.

In this embodiment, when both terminals perform a call service, the terminal that performs the call service may seize the bluetooth device, so that the call service data of the terminal that performs the call service may be output from the audio device of the terminal, and the call service data of the terminal that performs the call service is output using the bluetooth device.

In one embodiment, the first service and the second service are services corresponding to a bluetooth audio protocol, and step 206 includes: and if the priority of the first service is the same as that of the second service, the second terminal is a target data transmission terminal, and the first terminal is a non-target data transmission terminal. And sending a data transmission pause instruction to the first terminal, reducing the frequency of the received data of the link corresponding to the first terminal to a target frequency, and discarding the received data of the link corresponding to the first terminal. Step 208 includes: an audio data stream of the second terminal is received.

Specifically, the first service and the second service are services corresponding to a bluetooth audio protocol, and the priorities of the first service and the second service are the same, the second terminal is a target data transmission terminal, and the first terminal is a non-target data transmission terminal. The Bluetooth device sends a data transmission pause instruction to the first terminal first, keeps physical connection with the first terminal, including connection of an upper layer protocol A2DP, and if the first terminal supports a service corresponding to a Bluetooth communication protocol, connection of an upper layer protocol HFP can be kept, and meanwhile, the frequency of receiving audio data streams in a first terminal link is greatly reduced, namely, sending audio data to the Bluetooth device by the first terminal is reduced as much as possible, occupation of the bandwidth of the Bluetooth device by the first terminal is reduced, and further, if a small amount of audio data sent by the first terminal is received, the audio data is discarded and is not played. And simultaneously, receiving the audio data stream of the second terminal, and outputting the audio service data of the second terminal by the Bluetooth equipment. In one embodiment, a data transmission suspension instruction is sent to the first terminal, and if it is detected that the data transmission suspension is successful, that is, the data sent by the first terminal is not received, the frequency of the received data of the link corresponding to the first terminal does not need to be reduced to the target frequency. If the data transmission suspension is not successfully detected, that is, the data sent by the first terminal is still received, the frequency of the received data of the link corresponding to the first terminal is reduced to the target frequency, and further, the received data sent by the first terminal can be discarded.

If the first terminal needs to preempt the Bluetooth device, the first terminal needs to pause and then play again, and the Bluetooth device detects that the first terminal resumes receiving the service data of the first terminal after playing again, and meanwhile, the frequency of receiving the audio data stream in the second terminal link is greatly reduced. This case is equivalent to the case where the first service and the second service are both services corresponding to the bluetooth audio protocol, and when the bluetooth device is performing the first service data transmission with the second terminal, the bluetooth device receives the second service data transmission request sent by the first terminal, and determines that the first terminal is the target data transmission terminal and the second terminal is the non-target data transmission terminal.

In this embodiment, when two terminals both perform audio service, a terminal that performs audio service may seize a bluetooth device, so that audio service data of the terminal that performs audio service cannot be output by using the bluetooth device, and audio service data of the terminal that performs audio service is output by using the bluetooth device. The Bluetooth device sends a data transmission pause instruction to the non-target data transmission terminal, if the application of the non-target data transmission terminal can respond to the data transmission pause instruction, the data transmission can be directly paused, in addition, even if the data of the application of the non-target data transmission terminal does not respond to the data transmission pause instruction after switching, the data can still be transmitted to the Bluetooth device through physical connection, the Bluetooth device can discard the service data sent by the first terminal, so that the sound of the third-party application app in the switching process and after switching can not be played outside, the audio service data of the terminal which originally carries out the audio service can not be played outside, and the trouble of playing outside can not be brought to a user.

In one embodiment, the first service is a service corresponding to a bluetooth audio protocol, and the second service is a service corresponding to a bluetooth call protocol, and step 206 includes: and if the priority of the first service is lower than that of the second service, the second terminal is a target data transmission terminal, the first terminal is a non-target data transmission terminal, a data transmission pause instruction is sent to the first terminal, the received data frequency of the link corresponding to the first terminal is reduced to the target frequency, and the received data of the link corresponding to the first terminal is discarded. Step 208 includes: and creating an SCO link with the second terminal, and transmitting service data with the second terminal through the SCO link.

Specifically, the first service is a service corresponding to a bluetooth audio protocol, the second service is a service corresponding to a bluetooth call protocol, the second terminal is a target data transmission terminal, and the first terminal is a non-target data transmission terminal. The method comprises the steps that the Bluetooth equipment sends a data transmission pause instruction to the first terminal firstly, the physical connection with the first terminal is kept, including the connection of an upper layer protocol A2DP, if the first terminal supports a service corresponding to a Bluetooth communication protocol, the connection of an upper layer protocol HFP is also required to be kept, and meanwhile, the frequency of receiving an audio data stream in a first terminal link is greatly reduced, namely, the frequency that the first terminal sends audio data to the Bluetooth equipment is reduced as much as possible, the occupation of the first terminal on the bandwidth of the Bluetooth equipment is reduced, if a small amount of audio data sent by the first terminal are received, the audio data are discarded without being played, and the pause or silence of the audio service is realized. The bluetooth device may create an SCO link with the second terminal, and the call sound of the second terminal may be output from the bluetooth device. After the second terminal seizes the Bluetooth headset, the audio service of the first terminal cannot be seized back to the Bluetooth headset in the call process because the call service priority is higher than the audio service priority. In one embodiment, a data transmission suspension instruction is sent to the first terminal, and if it is detected that the data transmission suspension is successful, that is, the data sent by the first terminal is not received, the frequency of the received data of the link corresponding to the first terminal does not need to be reduced to the target frequency. And if the data transmission suspension is not successfully detected, that is, the data sent by the first terminal is still received, reducing the data receiving frequency of the link corresponding to the first terminal to the target frequency.

In this embodiment, when the terminal performing the call service needs to preempt the connection between the terminal performing the audio service and the bluetooth device, the priority of the call service is higher than that of the audio service, so that the preemption of the bluetooth device is successful, and thus the audio service data of the terminal performing the audio service cannot be output by using the bluetooth device, and the call service data of the terminal performing the call service is output by using the bluetooth device. The Bluetooth device sends a data transmission pause instruction to the non-target data transmission terminal, if the application of the non-target data transmission terminal can respond to the data transmission pause instruction, the data transmission can be directly paused, in addition, even if the data of the application of the non-target data transmission terminal after switching can still be transmitted to the Bluetooth device through physical connection, the Bluetooth device can discard the service data sent by the non-target data transmission terminal, so that the sound of the third-party application app in the switching process and after switching can not be played outside, the audio service data of the terminal which originally carries out the audio service can not be played outside, and the trouble of playing outside can not be brought to a user.

In one embodiment, the first service is a service corresponding to a bluetooth call protocol, and the second service is a service corresponding to a bluetooth audio protocol, and step 206 includes: if the priority of the first service is higher than that of the second service, the first terminal is a target data transmission terminal, the second terminal is a non-target data transmission terminal, a data transmission pause instruction is sent to the second terminal, the frequency of the received data of the link corresponding to the second terminal is reduced to the target frequency, and the received data of the link corresponding to the second terminal is discarded; step 208 includes: and continuously transmitting the service data with the first terminal through the original SCO link corresponding to the first terminal.

Specifically, the first service is a service corresponding to a bluetooth call protocol, the second service is a service corresponding to a bluetooth audio protocol, and the priority of the first service is higher than that of the second service, so that the first terminal is a target data transmission terminal and the second terminal is a non-target data transmission terminal. Because the conversation service optimization level is higher than the audio service, the bluetooth device keeps the conversation service of the first terminal, continues to transmit service data with the first terminal through the original SCO link corresponding to the first terminal, keeps physical connection with the second terminal, including connection of an upper protocol A2DP, and if the second terminal supports the service corresponding to the bluetooth conversation protocol, needs to keep connection of an upper protocol HFP, meanwhile, greatly reduces the frequency of receiving the audio data stream of the second terminal, sends a data transmission pause instruction to the second terminal, and discards the received data of the link corresponding to the second terminal. In one embodiment, a data transmission suspension instruction is sent to the second terminal, and if it is detected that the data transmission suspension is successful, that is, the data sent by the second terminal is not received, the frequency of the received data of the link corresponding to the second terminal does not need to be reduced to the target frequency. And if the data transmission suspension is not successfully detected, that is, the data sent by the second terminal is still received, reducing the data receiving frequency of the link corresponding to the second terminal to the target frequency.

In this embodiment, when the terminal that performs the audio service needs to seize the connection between the terminal that performs the call service and the bluetooth device, since the priority of the call service is higher than that of the audio service, the seizing of the bluetooth device fails, and thus the call service data of the terminal that performs the call service is output by using the bluetooth device continuously.
