All other embodiments, which are made by a person skilled in the art based on the embodiments of the application in light of the present disclosure, are intended to be within the scope of the application.
For ease of understanding, the relevant terms referred to in the present application will be described first.

2. An asynchronous connection-oriented (ACL) link for transmitting asynchronously required bluetooth data, such as control instructions, bluetooth music data, etc.
3. The telephone service protocol (hands-free profile, HFP) specifies that the hands-free device, referred to herein as an associated bluetooth device (e.g., a bluetooth headset, etc.), controls telephone-related operations.
4. Advanced audio distribution protocol (advanced audio distribution profile, A2 DP) defines protocols and procedures for enabling mono or stereo high quality audio content distribution over ACL links.
5. Audio/video remote control service protocol (AVRCP) defines features of how streaming media is controlled, including pause, stop, start playback, volume control, and other types of far-field control operations.
With development of technology, most of existing vehicles are deployed with vehicle-mounted systems so as to provide more convenient services for users. Taking car phone as an example, there are multiple phone types in car systems, such as bluetooth phone, internet phone, TBox phone, etc.
When a telephone call is carried out in the vehicle-mounted system, call voice can pass through the power amplifier of the vehicle-mounted loudspeaker, but the privacy of the mode is poor, and the call privacy of a user cannot be ensured. Currently, there are some vehicle-mounted systems that can connect a vehicle-mounted device with a bluetooth headset, through which music is listened to. Because the music data and the call data are transmitted by adopting different service protocols and different links, in order to realize the communication of the Bluetooth headset, the connection between the Bluetooth headset and the vehicle-mounted equipment is changed, and the link for transmitting the call data is established, so that the problems of complex operation and low call efficiency are caused, and the user experience is poor.
In an exemplary embodiment, the phone is a bluetooth phone, and since only one SCO link for transmitting call data can exist between bluetooth devices, if a user wants to answer the bluetooth phone through a bluetooth headset, the bluetooth connection between the vehicle-mounted device and the bluetooth headset needs to be disconnected through operation, so that the bluetooth headset and the terminal device of the incoming call are connected in a pairing manner, and the SCO link is established to transmit the call data of the bluetooth phone. Or in the scene that the user listens to music through the Bluetooth headset, the vehicle-mounted device receives the network telephone or the TBox telephone, and if the user wants to answer the network telephone or the TBox telephone through the Bluetooth headset, the SCO link which can be used for transmitting call data is rebuilt between the Bluetooth headset and the vehicle-mounted device through operation.
In view of this, the present application provides a vehicle-mounted communication method and a vehicle-mounted device, where the vehicle-mounted device can send a current communication state to the bluetooth headset, so that the bluetooth headset is in a play state, and the current communication state can be a dialing state, a waiting state, or an answered state. The in-vehicle device may convert the format of call data from the phone service protocol HFP format to the advanced audio distribution protocol A2DP format, that is, convert call data to music data that can be recognized and played by the bluetooth headset, and may transmit the music data to the bluetooth headset for playing through an ACL link for transmitting the music data. It should be understood that the ACL link is an existing link between the bluetooth headset and the in-vehicle device. In other words, in the application, the vehicle-mounted device only needs to convert the format of the related call data into the music data which can be identified and played by the Bluetooth headset, the Bluetooth headset can answer various phones in the vehicle-mounted system under the condition that the Bluetooth headset is not connected with the vehicle-mounted device, and the application has simple and convenient operation, improves the vehicle-mounted call efficiency and has good user experience.
It should be understood that the bluetooth headset according to the present application may be a bluetooth headset supporting music playing, which is not limited in this respect.
Before introducing a vehicle-mounted communication method and a vehicle-mounted communication device provided by the embodiment of the application, the following description is made.
First, in the embodiments shown below, terms and english abbreviations, such as listening events, are given as exemplary examples for convenience of description, and should not be construed as limiting the present application in any way. The present application does not exclude the possibility of defining other terms in existing or future protocols that perform the same or similar functions.
Second, the first, second and various numerical numbers in the embodiments shown below are merely for convenience of description and are not intended to limit the scope of the embodiments of the present application.
Third, "at least one" means one or more, and "a plurality" means two or more. "and/or" describes an association of associated objects, meaning that there may be three relationships, e.g., A and/or B, and that there may be A alone, while A and B are present, and B alone, where A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one of a, b and c may represent a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, wherein a, b, c may be single or plural.
In order to make the purpose and the technical scheme of the application clearer and more intuitive, the vehicle-mounted communication method and the vehicle-mounted device provided by the application are described in detail below with reference to the accompanying drawings and the embodiment. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Fig. 1 is a schematic flow chart of a method 100 for in-vehicle communication according to an embodiment of the present application. The method 100 may be applied to a system comprising a vehicle device and a bluetooth headset with an asynchronous connection-oriented ACL link established therebetween. As shown in fig. 1, the method 100 may include the steps of:
s101, the vehicle-mounted equipment acquires a current call state, wherein the current call state is a dialing state, a waiting state or an answered state.
S102, the vehicle-mounted equipment sends a play notice to the Bluetooth headset through the ACL link based on the current call state, wherein the play notice is used for notifying the Bluetooth headset that the Bluetooth headset is in a play state. Correspondingly, the Bluetooth headset receives a play notification from the vehicle-mounted device.
S103, the vehicle-mounted equipment converts the format of call data from a telephone service protocol HFP format to an advanced audio distribution protocol A2DP format.
Alternatively, the call data may include incoming call bell data, call voice data (i.e., the incoming call is completed), call waiting tone data, dial alert tone data, and the like.
It should be understood that the call data is PCM downlink data.
In one possible implementation manner, the vehicle-mounted device may perform a preprocessing operation and an encoding operation on PCM downlink data, so as to obtain call data after format conversion.
For example, the vehicle-mounted device may perform resampling and/or stereo processing on the PCM downlink data to obtain preprocessed PCM downlink data, and may perform SBC operation and/or AAC operation on the preprocessed PCM downlink data, so as to convert the format of the call data from HFP format to A2DP format, that is, obtain format-converted call data.
S104, the vehicle-mounted equipment transmits the call data with the converted format to the Bluetooth headset through the ACL link. Correspondingly, the Bluetooth headset receives the call data after the format conversion.
S105, the Bluetooth earphone plays the call data after the format conversion.
In the embodiment of the application, the vehicle-mounted device can send the current call state to the Bluetooth headset to enable the Bluetooth headset to be in the play state, and the current call state can be a dialing state, a to-be-answered state, a answered state or the like. The in-vehicle device may convert the format of call data from the phone service protocol HFP format to the advanced audio distribution protocol A2DP format, that is, convert call data to music data that can be recognized and played by the bluetooth headset, and may transmit the music data to the bluetooth headset for playing through an ACL link for transmitting the music data. It should be understood that the ACL link is an existing link between the bluetooth headset and the in-vehicle device. In other words, in the application, the vehicle-mounted device only needs to convert the format of the related call data into the music data which can be identified and played by the Bluetooth headset, the Bluetooth headset can answer various phones in the vehicle-mounted system under the condition that the Bluetooth headset is not connected with the vehicle-mounted device, and the application has simple and convenient operation, improves the vehicle-mounted call efficiency and has good user experience.
In addition, if the user wants to answer the call through the Bluetooth headset in the vehicle-mounted system when receiving the call in the vehicle-mounted system during driving, the complex operation that the user performs disconnection of the Bluetooth headset and the vehicle-mounted device or establishes a link capable of transmitting call data between the Bluetooth headset and the vehicle-mounted device can be effectively avoided, user experience is improved, and driving safety is also improved.
Optionally, after the vehicle-mounted device sends the call data after format conversion to the bluetooth headset through the ACL link, the vehicle-mounted device may also receive a control instruction from the bluetooth headset through the ACL link, where the control instruction is used to control the current call. The Bluetooth headset provides other ways for the user to control the call through the vehicle-mounted equipment, and compared with the vehicle-mounted equipment, the Bluetooth headset is closer to the user, so that the operation is more convenient, and the user experience is better.
It should be understood that the control instruction may be a control instruction to play music or a control instruction to pause music play.
In order to ensure that the above control instruction for playing music or the control instruction for suspending playing music can be used to control the current call, the vehicle-mounted device may convert the format of the above control instruction (the control instruction for playing music or the control instruction for suspending playing music) from the audio-video remote control service protocol AVRCP format to the HFP format, and may perform a control operation on the current call based on the control instruction after format conversion, where the control operation includes answering the incoming call or hanging up the incoming call.
It should be understood that the above-mentioned hanging up call may include ending an ongoing call (call coming or going), hanging up a not-yet-connected call going and hanging up a not-yet-connected call, etc., which the present application is not limited to.
It should be understood that, if the control instruction is a control instruction for playing music, the vehicle-mounted device may obtain the control instruction in HFP format by performing format conversion on the control instruction for playing music, and may answer the incoming call based on the control instruction. If the control instruction is a control instruction for suspending playing of music, the vehicle-mounted device may obtain the control instruction in HFP format by performing format conversion on the control instruction for suspending playing of music, and hang up the incoming call based on the control instruction.
For example, if the call data after format conversion is an incoming call ring, the bluetooth headset may play the call data after receiving the call data after format conversion, that is, the user may hear the incoming call ring through the bluetooth headset. If the user wants to answer the call, the user can send a command for controlling the call to the vehicle-mounted device by clicking a button of the Bluetooth headset, and the control command sent at the moment is a control command for playing music because the Bluetooth headset only supports playing and controlling of Bluetooth music, so that the vehicle-mounted device can convert the control command for playing music into a command for controlling the call, namely, a control command for answering the call, and answer the current call based on the control command for answering the call.
For example, if the converted call data is a call voice, that is, a state that the incoming call is already connected, the bluetooth headset may play the call voice after receiving the converted call data, that is, the user may hear the voice of the incoming call counterpart through the bluetooth headset. If the user wants to end the current call, the user can send a command for controlling the call to the vehicle-mounted device by clicking a button of the Bluetooth headset, and meanwhile, the Bluetooth headset only supports playing and controlling of Bluetooth music, so that the control command sent at the moment is a command for suspending playing of music, the vehicle-mounted device can convert the command for suspending playing of music into a command for controlling the call, namely, a command for controlling the hang-up of the call, and the current call is ended based on the command for controlling the hang-up of the call.
If the call data after format conversion is a call waiting sound, the user clicks a bluetooth headset button to think that the user wants to hang up the call, and at this time, the bluetooth headset may send a control instruction for suspending playing of music to the vehicle-mounted device, and the vehicle-mounted device converts the control instruction for suspending playing of music into a control instruction for hanging up the call, and may hang up the current call based on the control instruction for hanging up the call.
Table one shows the relationship of the format-converted call data, the control instruction, and the format-converted instruction.
List one
It should be understood that, in addition to the incoming call ring tone, the call voice and the call waiting tone shown above, the call data after format conversion may be a dial tone, etc., which is not limited in the present application.
As an optional embodiment, the system may further include a terminal device, where a synchronous connection-oriented SCO link may be established between the terminal device and the vehicle-mounted device, and the vehicle-mounted call method provided by the present application will be described below by taking the terminal device as a mobile phone as an example.
It should be understood that the terminal device may be other devices having a call function, such as a tablet computer, a notebook computer, a palm computer, a mobile internet device (mobile INTERNET DEVICE, MID), a wearable device, a Virtual Reality (VR) device, an augmented reality (augmented reality, AR) device, a wireless terminal in a smart home (smart home), a cellular phone, a cordless phone, a session initiation protocol (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a Personal Digital Assistant (PDA), a wearable device, etc., which are not limited thereto.

It should be understood that, in the case where the control instruction is a music playing instruction, the vehicle-mounted device may obtain the control instruction in HFP format by performing format conversion on the control instruction for playing music, and the mobile phone may perform an operation of answering the incoming call based on the control instruction in HFP format. Under the condition that the control instruction is a control instruction for suspending playing of music, the vehicle-mounted equipment can obtain the control instruction in the HFP format by performing format conversion on the control instruction for suspending playing of music, and send the control instruction in the HFP format to the mobile phone, and the mobile phone can execute the operation of hanging up the incoming call based on the control instruction in the HFP format.
For example, if the call data after format conversion is an incoming call ring, the bluetooth headset may play the call data after receiving the call data after format conversion, that is, the user may hear the incoming call ring through the bluetooth headset. If the user wants to answer the call, the control instruction of playing music can be sent to the vehicle-mounted equipment by clicking a button of the Bluetooth headset. The vehicle-mounted equipment can convert the control instruction of playing the music into a control instruction of answering the incoming call and send the control instruction to the mobile phone, and the mobile phone can execute the operation of answering the current incoming call based on the control instruction of answering the incoming call.
For example, if the converted call data is a call voice, i.e. a state that the incoming call is already connected, the bluetooth headset may play the call voice after receiving the converted call data, i.e. the user may hear the voice of the incoming call counterpart through the bluetooth headset. If the user wants to end the current call, the control instruction of suspending playing music can be sent to the vehicle-mounted device by clicking a button of the Bluetooth headset, the vehicle-mounted device can convert the control instruction of suspending playing music into a control instruction of hanging up the incoming call and send the control instruction to the mobile phone, and the mobile phone can end the current call based on the control instruction of hanging up the incoming call.
If the call data after format conversion is the call waiting sound, the user clicks the bluetooth headset button to think that the user wants to hang up the call, and at this time, the bluetooth headset may send a control instruction for suspending playing of music to the vehicle-mounted device, the vehicle-mounted device converts the control instruction for suspending playing of music into a control instruction for hanging up the call and sends the control instruction to the mobile phone, and the mobile phone may end the current call based on the control instruction for hanging up the call.
As above, in addition to the incoming call ring tone, the call voice, and the call waiting tone shown above, the call data after the format conversion may be a dial tone or the like, which is not limited in the present application.
In the embodiment of the application, the vehicle-mounted device can send the current call state acquired from the terminal device to the Bluetooth headset so that the Bluetooth headset is in a playing state, and can convert the format of call data acquired from the terminal device from a telephone service protocol HFP format to an advanced audio distribution protocol A2DP format, namely, convert the call data into music data which can be identified and played by the Bluetooth headset. The vehicle-mounted equipment can send the call data after the format conversion to the Bluetooth headset for playing through an ACL link for transmitting music data, so that the Bluetooth headset can answer the call. In other words, the vehicle-mounted device only needs to convert the format of the related call data into the music data which can be identified and played by the Bluetooth headset, the Bluetooth headset can realize the answering of the Bluetooth telephone in the vehicle-mounted system without changing the connection of the Bluetooth headset with the vehicle-mounted device, and the vehicle-mounted device is simple and convenient to operate, improves the vehicle-mounted call efficiency and has good user experience.
It should be understood that the call data can be transmitted between the vehicle-mounted device and the terminal device through the established SCO link, and because the vehicle-mounted device converts the format of the call data, the established ACL link between the Bluetooth headset and the vehicle-mounted device is not required to be changed into the SCO link, so that the problem that the current Bluetooth chip cannot establish two SCO links is effectively avoided, hardware improvement is avoided, and cost is reduced.
It should be understood that the mobile phone, the in-vehicle device, and the bluetooth headset share one ACL link to transmit HFP data (current call state and control call instruction), A2DP data (call data after format conversion), and AVRCP data (current call state and music control instruction after format conversion).
Illustratively, the A2DP data may be transmitted through first information in the ACL link, the HFP data may be transmitted through a second channel in the ACL link, and the AVRCP data may be transmitted through a third channel in the ACL link.
For easy understanding, the method for controlling a call by a vehicle-mounted call and the method for controlling a call by a bluetooth headset provided by the present application will be described below with reference to fig. 3 and 4, respectively, in a scene that an incoming call has been put through.
Fig. 3 shows a schematic flow chart of a car talk method 300 in a call-on scenario. As shown in fig. 3, in the case of an incoming call having been connected, the vehicle-mounted device may acquire call voice data of the cellular phone, i.e., PCM downlink data, by using the call SCO link, and may perform resampling and/or stereo processing on the call voice data, and SBC operation and/or AAC encoding operation, so as to convert the format of the call voice data from HFP format to A2DP format. The vehicle-mounted device can send the call voice data after format conversion, namely the A2DP format data, to the Bluetooth headset for playing through a first channel of the ACL link.
It should be understood that the above call voice data may also be understood as voice data of the counterpart in the call. If the user replies to the call counterpart, the vehicle-mounted device can grasp the reply voice from the microphone near the main driver and send the reply voice to the mobile phone through the SCO link as data of the mobile phone microphone, namely PCM uplink data, so that the call counterpart receives the reply voice of the user.
Fig. 4 is a schematic diagram of a method 400 for controlling a vehicle-mounted call by using a bluetooth headset according to an embodiment of the present application. As shown in fig. 4, in the case of an incoming call having been put through, the user may obtain a call voice through the bluetooth headset, and if the user wants to end the current call, the user may send a music control instruction (a control instruction to pause music playing), that is, AVRCP data, to the vehicle-mounted device through the third channel of the ACL link by clicking a button on the bluetooth headset. The in-vehicle apparatus may convert the control instruction to suspend music play into a control instruction to talk (control instruction to hang up a talk), that is, convert the format of the control instruction to suspend voice play from AVRCP format to HFP format, and transmit to the handset through the second channel of the ACL link. The mobile phone can end the current call based on the control instruction of the hang-up call.
It should be understood that, before the user can obtain the call voice through the bluetooth headset, the vehicle-mounted device may also receive the call state from the mobile phone through the second channel of the ACL link, and may send the call state to the bluetooth headset through the third channel of the ACL link, so that the bluetooth headset is in a play state. The call state may be an incoming call non-connection state, an incoming call connection state, an outgoing call non-connection state, or an outgoing call connection state, which is not limited in the present application.
