Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments that can be made by one skilled in the art based on the embodiments in the present application in light of the present disclosure are within the scope of the present application.
For ease of understanding, the relevant terms referred to in this application will first be described.
1. Synchronous Connection Oriented (SCO) link: and the uplink and downlink data are used for transmitting call audio.
2. Asynchronous connection-oriented (ACL) links: for transmitting non-synchronization required bluetooth data, such as control commands, bluetooth music data, etc.
3. The telephone-free profile (HFP) specifies that a hands-free device controls phone-related operations, where the hands-free device refers to a related bluetooth device (e.g., a vehicle bluetooth or bluetooth headset).
4. Advanced audio distribution profile (A2 DP), defines protocols and procedures for enabling mono or stereo high quality audio content distribution over ACL links.
5. The audio/video remote control profile (AVRCP) defines how to control the characteristics of streaming media, including pause, stop, start playback, volume control, and other types of far-field control operations.
With the development of science and technology, most of the existing vehicles are provided with vehicle-mounted systems, so that more convenient services can be provided for users. Taking the car call as an example, a plurality of telephone types exist in the car system, such as a bluetooth telephone, a network telephone or a TBox telephone.
When a telephone call is carried out in a vehicle-mounted system, call voice can be amplified through a vehicle-mounted loudspeaker, but the privacy of the method is poor, and the call privacy of a user cannot be guaranteed. Currently, some vehicle-mounted systems are available to connect a vehicle-mounted device to a bluetooth headset and listen to music through the bluetooth headset. Because music data and conversation data are transmitted by different service protocols and different links, in order to realize the conversation of the Bluetooth headset, the connection between the Bluetooth headset and the vehicle-mounted equipment needs to be changed, and the link for transmitting the conversation data is established, so that the problems of complex operation, low conversation efficiency and poor user experience exist.
For example, the phone is a bluetooth phone, and since only one SCO link for transmitting call data exists 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 by operation, so that the bluetooth headset and the incoming terminal device are connected in a pairing manner, and the SCO link is established to transmit the call data of the bluetooth phone. Or, in a scene that the user listens to music through the bluetooth headset, the vehicle-mounted device receives the internet phone or the TBox phone, and if the user wants to listen to the internet phone or the TBox phone through the bluetooth headset, the SCO link which can be used for transmitting call data is reestablished between the bluetooth headset and the vehicle-mounted device through operation.
In view of this, the present application provides a vehicle-mounted call method and a vehicle-mounted device, where the vehicle-mounted device may send a current call state to a bluetooth headset, so that the bluetooth headset is in a play state, and the current call state may be a dialing state, a state to be answered, or an answered state, and the like. The vehicle-mounted device can convert the format of the call data from the telephone service protocol HFP format into the advanced audio distribution protocol A2DP format, i.e. convert the call data into music data which can be recognized and played by the Bluetooth headset, and can send the music data to the Bluetooth headset through an ACL link for transmitting the music data to be played. 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 music data which can be recognized and played by the Bluetooth headset, and the Bluetooth headset can answer various calls in the vehicle-mounted system under the condition that the connection between the Bluetooth headset and the vehicle-mounted device is not changed, so that the operation is simple and convenient, the efficiency of vehicle-mounted call is improved, and the user experience is good.
It should be understood that the bluetooth headset related to the present application may be a bluetooth headset supporting music playing, and the present application is not limited thereto.
Before introducing the vehicle-mounted communication method and the vehicle-mounted communication device provided by the embodiment of the application, the following points are explained.
First, in the embodiments shown below, terms and english abbreviations such as listening events are exemplary examples given for convenience of description, and should not limit the present application in any way. This application is not intended to exclude the possibility that other terms may be defined in existing or future protocols to carry out 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, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (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 and c can be single or multiple.
In order to make the purpose and technical solution of the present application clearer and more intuitive, the following will describe in detail the vehicle-mounted communication method and the vehicle-mounted device provided by the present application with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a schematic flowchart of a vehicle-mounted call method 100 provided in an embodiment of the present application. The method 100 may be applied to a system including an in-vehicle device and a bluetooth headset between which an asynchronous connection-oriented ACL link is established. As shown in fig. 1, the method 100 may include the following steps:
s101, the vehicle-mounted equipment acquires a current call state, wherein the current call state is a dialing state, a waiting state or an answering state.
And S102, the vehicle-mounted equipment sends a play notification to the Bluetooth headset through the ACL link based on the current call state, wherein the play notification is used for notifying the Bluetooth headset to be in a play state. Correspondingly, the Bluetooth headset receives a play notification from the in-vehicle device.
S103, the vehicle-mounted device converts the format of the call data from the HFP format into the A2DP format.
Alternatively, the call data may include incoming call ringtone data, call voice data (i.e., incoming call is connected), outgoing call waiting tone data, dial tone data, and the like.
It should be understood that the call data is PCM downstream data.
In a possible implementation manner, the vehicle-mounted device may perform a preprocessing operation and an encoding operation on the PCM downlink data, so as to obtain the format-converted call data.
For example, the in-vehicle device may perform resampling processing and/or stereo processing on the PCM downstream data to obtain preprocessed PCM downstream data, and may perform SBC operation and/or AAC operation on the preprocessed PCM downstream data to convert the format of the call data from the HFP format to the A2DP format, that is, to obtain format-converted call data.
And S104, the vehicle-mounted equipment sends the conversation data after format conversion to the Bluetooth headset through the ACL link. Correspondingly, the Bluetooth headset receives the conversation data after the format conversion.
And S105, the Bluetooth headset plays the conversation 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, so that the bluetooth headset is in the playing state, and the current call state can be a dialing state, a waiting state, an answered state or the like. The vehicle-mounted device can convert the format of the call data from the telephone service protocol HFP format into the advanced audio distribution protocol A2DP format, i.e. convert the call data into music data which can be recognized and played by the Bluetooth headset, and can send the music data to the Bluetooth headset through an ACL link for transmitting the music data to be played. 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 music data which can be recognized and played by the Bluetooth headset, the Bluetooth headset can answer various calls in the vehicle-mounted system under the condition that the connection between the Bluetooth headset and the vehicle-mounted device is not changed, the operation is simple and convenient, the vehicle-mounted call efficiency is improved, and the user experience is good.
In addition, when a call in the vehicle-mounted system is received during driving and a user wants to answer the call through a Bluetooth headset in the vehicle-mounted system, the vehicle-mounted call method provided by the application can effectively avoid the user from executing complicated operations of disconnecting the Bluetooth headset from the vehicle-mounted device or establishing a link capable of transmitting call data between the Bluetooth headset and the vehicle-mounted device, so that the driving safety is improved while the user experience is improved.
Optionally, after the vehicle-mounted device sends the format-converted call data to the bluetooth headset through the ACL link, the vehicle-mounted device may further 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 is provided with 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, the operation is more convenient, and the user experience is better.
It should be understood that the control command may be a control command to play music or a control command to pause music play.
In order to ensure that the control instruction for playing music or the control instruction for pausing the playing of music can be used for controlling the current call, the vehicle-mounted device can convert the format of the control instruction (the control instruction for playing music or the control instruction for pausing the playing of music) from the AVRCP format into the HFP format, and can perform control operation on the current call based on the control instruction after format conversion, wherein the control operation comprises answering the call or hanging up the call.
It should be understood that the hanging up of the incoming call may include ending an ongoing call (incoming call or outgoing call), hanging up an outgoing call that is not connected, hanging up an incoming call that is not connected, and the like, and the present application is not limited thereto.
It should be understood that, if the control instruction is a control instruction for playing music, the in-vehicle device may obtain the control instruction in the 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 pausing music playing, the vehicle-mounted device may perform format conversion on the control instruction for pausing music playing to obtain the HFP format control instruction, and hang up the incoming call based on the control instruction.
For example, if the call data after format conversion is an incoming call ringtone, 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 ringtone through the bluetooth headset. If the user wants to answer the incoming call, a command for controlling the call can be sent to the vehicle-mounted equipment by clicking a button of the Bluetooth headset, and the Bluetooth headset only supports the playing and controlling of the Bluetooth music, so that the control command sent at the moment is a control command for playing the music, the vehicle-mounted equipment can convert the control command for playing the music into a command for controlling the call, namely a control command for answering the incoming call, and the current incoming call is answered based on the control command for answering the incoming call.
For example, if the call data after format conversion is a call voice, that is, a state that an incoming call is connected, after receiving the call data after format conversion, the bluetooth headset may play the call voice, that is, a user may hear a voice of an incoming call party through the bluetooth headset. If the user wants to end the current call, a command for controlling the call can be sent to the vehicle-mounted device by clicking a button of the bluetooth headset, and as above, the bluetooth headset only supports the playing and controlling of the bluetooth music, the control command sent at this time is a control command for pausing the playing of the music, and the vehicle-mounted device can convert the control command for pausing the playing of the music into a command for controlling the call, namely a control command for hanging up the incoming call, and end the current call based on the control command for hanging up the incoming call.
For example, if the call data after the format conversion is an outgoing call waiting tone, the user clicks a button of the bluetooth headset, and may consider that the user wants to hang up the outgoing call, at this time, the bluetooth headset may send a control instruction for suspending music playing to the vehicle-mounted device, and the vehicle-mounted device converts the control instruction for suspending music playing into a control instruction for hanging up the outgoing call, and may hang up the current outgoing call based on the control instruction for hanging up the outgoing call.
Table one shows the relationship between the call data after format conversion, the control command, and the command after format conversion.
Watch 1
It should be understood that, besides the incoming call ring tone, the call voice and the outgoing call waiting tone shown above, the call data after format conversion may also be a dial tone, etc., which is not limited in this application.
As an optional embodiment, the system may further include a terminal device, where the terminal device may establish a synchronous connection-oriented SCO link with the vehicle-mounted device, and the vehicle-mounted call method provided in this 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 communication function besides a mobile phone, such as a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in a smart home (smart home), a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a wearable device, and the like, which have a wireless communication function, and the embodiments of the present application are not limited thereto.

S201, the mobile phone sends a current call state to the vehicle-mounted equipment, wherein the current call state is a dialing state, a waiting state or an answered state. Correspondingly, the vehicle-mounted equipment receives the current call state from the mobile phone.
S202, the vehicle-mounted equipment sends a play notification to the Bluetooth headset based on the current call state, and the play notification is used for notifying the Bluetooth headset of being in a play state. Correspondingly, the Bluetooth headset receives a play notification from the in-vehicle device.

S203, the mobile phone sends the call data to the vehicle-mounted equipment. Correspondingly, the vehicle-mounted equipment receives call data from the mobile phone.
Illustratively, the in-vehicle device may receive call data from a handset over the SCO link.
As above, the call data may include incoming call ringtone data, call voice data (i.e., the call has been connected), outgoing call waiting tone data, dial tone data, and the like.
And S204, converting the format of the call data into the advanced audio distribution protocol A2DP format by the telephone service protocol HFP format through the vehicle-mounted device.
As above, the call data is PCM downstream data.
In a possible implementation manner, the vehicle-mounted device may perform a preprocessing operation and an encoding operation on the PCM downlink data, so as to obtain the format-converted call data.
For example, the in-vehicle device may perform resampling processing and/or stereo processing on the PCM downstream data to obtain preprocessed PCM downstream data, and may perform SBC operation and/or AAC operation on the preprocessed PCM downstream data to convert the format of the call data from the HFP format to the A2DP format, that is, to obtain format-converted call data.
