[0092] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0093] Taking a mobile phone as an electronic device and a Bluetooth headset as a Bluetooth device as an example, when making a voice call using a Bluetooth headset connected to the phone, the headset receives the voice data sent by the phone, decodes the voice data to obtain the voice signal from the other end of the call, and then uses a call algorithm to adjust the frequency response, gain, and other aspects of the voice signal. The processed voice signal is then converted into an analog signal and played through a speaker. Currently, common voice codec methods include narrowband voice codec and wideband voice codec. To accommodate the processing of voice data decoded by these two methods, the call algorithm in the Bluetooth headset has two sets of algorithm parameters: one set corresponding to wideband voice codec, used when processing voice data between the phone and the Bluetooth headset using wideband voice codec, and another set corresponding to narrowband voice codec, used when processing voice data between the phone and the Bluetooth headset using narrowband voice codec.

[0094] If a user makes a voice call using a Bluetooth headset connected to their phone, the voice codec used to transmit voice data between the phone and the carrier's network may be narrowband or wideband voice codec, and the voice codec used to transmit voice data between the phone and the Bluetooth headset may also be narrowband or wideband voice codec. Since most mobile phones nowadays have broadband voice codec capabilities, when Bluetooth headsets also have broadband voice codec capabilities, except in special cases such as very poor network conditions, regardless of whether the voice codec between the phone and the operator's network is narrowband or broadband, the voice data transmitted between the phone and the Bluetooth headset will be encoded and decoded using broadband voice codec. In this case, if the phone and operator's network use narrowband voice codec for voice data transmission, while the phone and Bluetooth headset use broadband voice codec for voice data transmission, then the call algorithm on the Bluetooth headset side will use the algorithm parameters corresponding to broadband voice codec to process the other end's voice signal. However, because the phone and operator's network use narrowband voice codec for voice data transmission, even if the phone and Bluetooth headset use broadband voice codec, the decoded voice signal from the other end obtained by the Bluetooth headset is actually a narrowband voice signal. This will result in poor processing of the other end's voice signal by the call algorithm, leading to poor call quality and a reduced user experience.

[0095] Therefore, this application provides a data processing method that can solve the above problems, optimize the voice call effect when using Bluetooth devices, and improve the user experience.

[0096] The method provided in this application can be applied to electronic devices capable of making voice calls, such as mobile phones; it can also be applied to Bluetooth devices that can assist electronic devices in making voice calls, such as Bluetooth headsets, wearable devices such as smartwatches, and in-vehicle communication devices.

This memory can store instructions or data that the processor 110 has just used or that are used repeatedly. If the processor 110 needs to use the instruction or data again, it can retrieve it directly from the memory.

In some embodiments, the audio module 170 can also transmit audio signals to the wireless communication module 160 via the PCM interface, enabling the function of answering phone calls through a Bluetooth headset. Both the I2S interface and the PCM interface can be used for audio communication.

[0105] The UART interface is a universal serial data bus used for asynchronous communication. This bus can be a bidirectional communication bus. It converts the data to be transmitted between serial and parallel communication.

In some embodiments, at least some functional modules of the mobile communication module 150 may be housed in the processor 110. In some embodiments, at least some functional modules of the mobile communication module 150 and at least some modules of the processor 110 may be housed in the same device.

[0111] The modem processor may include a modulator and a demodulator. The modulator modulates the low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs sound signals through audio devices (not limited to speaker 170A, receiver 170B, etc.) or displays images or videos through the display screen 194. In some embodiments, the modem processor may be a separate device. In other embodiments, the modem processor may be independent of the processor 110 and may be housed in the same device as the mobile communication module 150 or other functional modules.

The program storage area may store the operating system, at least one application program required for a function (such as sound playback, image playback, etc.), etc. The data storage area may store data created during the use of electronic device 100 (such as audio data, phonebook, etc.). Furthermore, internal memory 121 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, universal flash storage (UFS), etc. Processor 110 executes various functional applications and data processing of electronic device 100 by running instructions stored in internal memory 121 and / or instructions stored in memory located in the processor.

[0115] Electronic device 100 can implement audio functions, such as music playback and recording, through audio module 170, speaker 170A, receiver 170B, microphone 170C, headphone jack 170D, and application processor.

[0116] The audio module 170 is used to convert digital audio information into analog audio signals for output, and also to convert analog audio input into digital audio signals.

In some embodiments, the audio module 170 may be located in the processor 110, or some functional modules of the audio module 170 may be located in the processor 110.

[0117] The speaker 170A, also known as a "loudspeaker," is used to convert audio electrical signals into sound signals. The electronic device 100 can listen to music or make hands-free calls through the speaker 170A.

[0118] The receiver 170B, also known as the "earpiece," is used to convert audio electrical signals into sound signals. When the electronic device 100 answers a telephone call or voice message, the receiver 170B can be brought close to the ear to listen to the voice.

[0121] The software system of electronic device 100 can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. This embodiment of the invention uses the layered architecture Android system as an example to exemplify the software structure of electronic device 100.

[0122] Figure 2 This is a schematic diagram of the structure of a Bluetooth device according to an embodiment of the present invention, as shown below. Figure 2 As shown, the Bluetooth device 200 may include a processor 210, a Bluetooth module 220, and an audio module 230. The processor 210, Bluetooth module 220, and audio module 230 can communicate with each other through internal connection channels to transmit control and / or data signals.

[0123] The Bluetooth module 220 is used in conjunction with the processor 210 to enable Bluetooth communication with other devices.

[0124] The audio module 230 is used to convert digital audio information into analog audio signals for output, and also to convert analog audio input into digital audio signals. The audio module 230 can also be used for encoding and decoding audio signals. In some embodiments, the audio module 230 may be located in the processor 210, or some functional modules of the audio module 230 may be located in the processor 210.

[0125] See Figure 3 This is an example diagram illustrating the applicable scenario of the data processing method in the embodiments of this application, such as... Figure 3As shown, it includes: Bluetooth device 310, electronic device 320, and network-side device 330; electronic device 320 can establish a voice channel with the operator's network through network-side device 330 to realize voice calls with other electronic devices; Bluetooth device 310 can establish a voice channel with electronic device 320, and users can realize voice calls on the side of electronic device 320 through Bluetooth device 310.

[0126] In this embodiment, the Bluetooth device can be a Bluetooth headset, a smartwatch with Bluetooth communication function, etc. The electronic device can be a mobile phone or other electronic device with voice call capability. In the following embodiments, a mobile phone as the electronic device and a Bluetooth headset as the Bluetooth device are used as examples for illustrative purposes.

[0127] Figure 4 This is a flowchart of one embodiment of the data processing method of this application, as shown below. Figure 4 As shown, the method may include:

[0128] Step 401: The mobile phone and Bluetooth headset are successfully paired.

[0129] See Figure 5 This section explains the pairing process between the phone and the Bluetooth headset. Bluetooth functionality is typically a feature within the phone's operating system. Users access the Bluetooth settings interface within their phone's operating system, for example... Figure 5 As shown in the first image, the user turns on their phone's Bluetooth by selecting the "Open" control. The phone detects this, searches for nearby electronic devices that can be paired, and displays the found devices to the user. If the Bluetooth headset is also enabled, the phone can display the headset on the screen. For example... Figure 5 As shown in the second image, when the user selects the "Bluetooth Headset" control, the phone receives a pairing instruction for the Bluetooth headset, and the pairing process begins between the phone and the headset. The specific pairing process will not be detailed here. Afterwards, for example... Figure 5 As shown in the third image, after the mobile phone and Bluetooth headset are paired, a pairing confirmation message can be displayed to the user.

[0130] Step 402: The mobile phone, as the called party in the voice call, establishes a voice channel with the operator's network through the network-side equipment, and obtains and stores the first voice codec method. The first voice codec method is the voice codec method used between the mobile phone and the operator's network in this voice call.

[0131] In this process, the mobile phone receives an incoming call and prompts the user. If the user chooses to answer the call, the mobile phone receives the user's call answering action. This serves as the parameter negotiation process for the voice channel between the called party and the network-side device, as well as the voice channel establishment process. This voice channel is used to transmit voice data during the voice call. During the voice channel establishment process, the signaling sent from the network-side device to the mobile phone can carry the necessary parameters used for the voice channel. One of these parameters is the aforementioned first voice encoding / decoding method. Accordingly, the mobile phone can obtain the first voice encoding method from this signaling. The specific parameter negotiation process for the voice channel is not detailed in this embodiment.

[0132] The mobile phone can set bandwidth status information for this voice call to store the aforementioned first voice codec. The bandwidth status information set in the phone can have different values ​​to represent different voice codecs used in the voice call, and its value corresponds to the acquired first voice codec. For example, a bandwidth status information value of 4 indicates narrowband voice codec, and a bandwidth status information value of 8 indicates wideband voice codec. Accordingly, if the acquired first voice codec is narrowband voice codec, the bandwidth status information in the phone can be set to 4; if the acquired first voice codec is wideband voice codec, the bandwidth status information in the phone can be set to 8.

[0133] Step 403: The mobile phone obtains the voice codec supported by the Bluetooth headset, and determines the second voice codec based on the voice codec supported by the mobile phone and the Bluetooth headset.

[0134] The second voice codec method is the voice codec method negotiated between the mobile phone and the Bluetooth headset for the voice channel to be established.

[0135] The mobile phone can obtain the voice codecs supported by the Bluetooth headset, which may include:

[0136] The mobile phone sends a negotiation request message to the Bluetooth headset. The negotiation request message is used to request the voice codec supported by the Bluetooth headset.

[0137] In response to the negotiation request message, the Bluetooth headset sends a negotiation response message to the mobile phone. This response message includes the voice codecs supported by the Bluetooth headset. The supported codecs can be carried in the BCS field of the negotiation response message. A BCS value of 1 indicates that the Bluetooth headset supports narrowband voice codecs, while a value of 2 indicates that the Bluetooth headset supports wideband voice codecs.

[0138] In related technologies, the establishment of a voice channel between a mobile phone and a Bluetooth headset typically involves a parameter negotiation process and a voice channel establishment process. The parameter negotiation process enables the mobile phone to obtain the relevant parameters of the voice channel supported by the Bluetooth headset. Specifically, this process may include: the mobile phone sending a parameter negotiation request message to the Bluetooth headset, requesting the parameters supported by the Bluetooth headset; and the Bluetooth headset responding to the parameter negotiation request message by sending a parameter negotiation response message, which indicates to the mobile phone the relevant parameters of the voice channel supported by the Bluetooth headset. These parameters generally include the voice codecs supported by the Bluetooth headset. Therefore, the negotiation request message and response message used to obtain the voice codecs supported by the Bluetooth headset can be implemented using the aforementioned parameter negotiation request message and response message.

[0139] The phone can determine the second voice codec based on the voice codec supported by the phone and the Bluetooth headset. Specifically, if both the phone and the Bluetooth headset support wideband voice codec, then the second voice codec is determined to be wideband voice codec. If at least one of the phone and the Bluetooth headset only supports narrowband voice codec, then the second voice codec is determined to be narrowband voice codec.

[0140] Step 404: The mobile phone determines whether the second voice codec is wideband voice codec. If yes, proceed to step 405; otherwise, proceed to step 407.

[0141] Step 405: The mobile phone determines whether the first voice codec recorded in the mobile phone is a narrowband voice codec. If yes, proceed to step 406; otherwise, proceed to step 408.

[0142] Step 406: The mobile phone sends a codec instruction message to the Bluetooth headset. The voice codec method carried in the codec instruction message is narrowband voice codec.

[0143] The codec indication message can be implemented using existing signaling or newly defined signaling. For example, the codec indication message can be a newly defined signaling based on transmission protocols such as AT, Serial Port Profile (SPP), ECHO, or Bluetooth Low Energy (BLE) broadcasting. This newly defined signaling sets a band field, and the value of the band field indicates that the voice codec method is narrowband voice codec. Continuing the example in step 402, the value of the band field can be 4.

[0144] This step is optional.

[0145] Step 407: The mobile phone and Bluetooth headset establish a voice path based on narrowband voice codec. The mobile phone and Bluetooth headset respectively use narrowband voice codec to encode and decode the voice data between the mobile phone and Bluetooth headset. The Bluetooth headset uses the call algorithm corresponding to the narrowband voice codec to process the decoded voice data. This branch of the process ends.

[0146] Establishing a voice path between a mobile phone and a Bluetooth headset based on narrowband voice codec can include:

[0147] The mobile phone sends a channel establishment request message to the Bluetooth headset; the voice codec method carried in the channel establishment request message is narrowband voice codec.

[0148] The Bluetooth headset sends a channel establishment response message to the mobile phone.

[0149] The decoded voice data is the same as the voice data from the other end of the voice call. Bluetooth headsets can obtain a call algorithm corresponding to the narrowband voice codec by setting the parameters of the call algorithm to those of the narrowband voice codec.

[0150] Step 408: The mobile phone and Bluetooth headset establish a voice channel based on the wideband voice codec. The mobile phone and Bluetooth headset respectively use the wideband voice codec to encode and decode the voice data between the mobile phone and the Bluetooth headset; the Bluetooth headset uses the call algorithm corresponding to the wideband voice codec to process the decoded voice data; this branch of the process ends.

[0151] Bluetooth headsets can obtain a call algorithm corresponding to narrowband voice codec by setting the parameters of the call algorithm to those of wideband voice codec.

[0152] In the prior art, after the mobile phone and Bluetooth headset negotiate the second voice codec in step 403, a voice path is directly established between the mobile phone and Bluetooth headset based on the second voice codec. At this point, if the second voice codec negotiated between the mobile phone and Bluetooth headset is wideband voice codec, while the first voice codec between the mobile phone and the operator network is narrowband voice codec, then the actual voice data obtained by the Bluetooth headset from the other end of the voice call is narrowband voice data. Since the Bluetooth headset uses the call algorithm corresponding to wideband voice codec to process the narrowband voice data, it will affect the voice call quality. Figure 4In the method shown, after the mobile phone and Bluetooth headset negotiate the second voice codec, the mobile phone further selects the case where the second voice codec is wideband voice codec and the first voice codec is narrowband voice codec through the judgment in steps 404 and 405. The voice channel established between the mobile phone and Bluetooth headset uses narrowband voice codec to transmit voice data. Correspondingly, the Bluetooth headset uses the call algorithm corresponding to narrowband voice codec to process the voice data of the other end of the voice call, which solves the problem of poor voice call quality in this case.

[0153] In this application, the voice codec used in the established voice channel between the mobile phone and the Bluetooth headset is also referred to as the third voice codec. For example, the third voice codec in step 407 is narrowband voice codec, and the third voice codec in step 408 is wideband voice codec.

[0154] Different from Figure 4 The method shown is that the mobile phone acts as the called party in a voice call. Figure 6 In the data processing method shown, the mobile phone acts as the calling end of the voice call, and the user initiates the voice call by operating the Bluetooth headset. For example... Figure 6 As shown, the method may include:

[0155] Step 601: The mobile phone and Bluetooth headset are successfully paired.

[0156] The implementation of this step can be referred to the description in step 401, and will not be repeated here.

[0157] Step 602: The Bluetooth headset receives a call instruction and sends a call request message to the mobile phone. The call request message is used to request a voice call and includes the voice codec supported by Bluetooth.

[0158] If the Bluetooth headset supports wideband voice codec, the voice codec method carried in the call request message is wideband voice codec; otherwise, it is narrowband voice codec.

[0159] Currently, many Bluetooth headsets support making calls from the headset side. When a user makes a call from the Bluetooth headset side, the Bluetooth headset can receive call instructions.

[0160] Step 603: In response to the call request message, the mobile phone determines the second voice codec method according to the voice codec methods supported by the mobile phone and the Bluetooth headset respectively, and establishes a voice channel with the Bluetooth headset based on the second voice codec method.

[0161] In this step, the third voice codec method of the established voice channel is the second voice codec method negotiated between the mobile phone and the Bluetooth headset.

[0162] Step 604: The mobile phone establishes a voice channel with the operator's network through the network-side equipment and obtains the first voice codec.

[0163] For instructions on how to implement this step, please refer to [link / reference]. Figure 4 The corresponding description in [the document] will not be repeated here.

[0164] Step 605: The mobile phone determines whether the second voice codec is a broadband voice codec. If it is, proceed to step 606; otherwise, this branch of the process ends.

[0165] If the result is negative, it means that the second voice codec is a narrowband voice codec. In this case, there is no need to adjust the voice path already established between the mobile phone and the Bluetooth headset. You can continue to make voice calls on the existing voice path.

[0166] Step 606: The mobile phone determines whether the first voice codec is narrowband voice codec. If yes, proceed to step 607; otherwise, this branch of the process ends.

[0167] If the result is negative, it means that the first voice codec is wideband voice codec, and the second voice codec is also wideband voice codec. There is no need to adjust the voice codec on the Bluetooth headset side; you can continue to make voice calls on the existing voice channel.

[0168] Step 607: The mobile phone sends a codec instruction message to the Bluetooth headset. The voice codec method carried in the codec instruction message is narrowband voice codec. Then proceed to step 608.

[0169] Step 608: The Bluetooth headset uses the call algorithm corresponding to the narrowband voice codec to process the decoded voice data.

[0170] Specifically, Bluetooth headsets can switch the parameters in the call algorithm from those corresponding to wideband voice codecs to those corresponding to narrowband voice codecs to obtain the call algorithm corresponding to narrowband voice codecs.

[0171] Figure 6 The method shown selects a case where the second voice codec is wideband voice codec and the first voice codec is narrowband voice codec. Then, the call algorithm is switched in the Bluetooth headset. This solves the problem of mismatch between the call algorithm and the bandwidth of the voice data to be processed when the mobile phone is the calling end and the user initiates a voice call on the Bluetooth headset side. This is because the second voice codec is wideband voice codec and the first voice codec is narrowband voice codec. As a result, the problem of poor voice call quality is solved.

[0172] The above Figure 4 In the method shown, the mobile phone acts as the called party in the voice call. Figure 6 In the method shown, the mobile phone acts as the calling end of the voice call, and the user initiates the voice call from the Bluetooth headset. This differs from the methods described above. Figure 7 and Figure 8 In the data processing method of the present application embodiment, the mobile phone acts as the calling end of the voice call, and the user initiates the voice call from the mobile phone side.

[0173] When a user initiates a voice call from their mobile phone, the phone needs to establish voice pathways with both the network device and the Bluetooth headset. This can result in two scenarios:

[0174] Scenario 1: The voice communication channel between the mobile phone and the network device is established earlier than the voice communication channel between the mobile phone and the Bluetooth device.

[0175] Scenario 2: The establishment of the voice channel between the mobile phone and the network-side device is later than the establishment of the voice channel between the mobile phone and the Bluetooth device.

[0176] Figure 7 The data processing method shown in the embodiment of this application is applicable to case one, and... Figure 4 The main difference between the methods shown is that: Figure 4 Step 402 is replaced with step 701 below, specifically,

[0177] Step 701: The mobile phone receives the call instruction operation, acts as the calling end of the voice call, establishes a voice channel with the operator's network through the network-side equipment, and obtains and stores the first voice codec.

[0178] When a user makes a call on their mobile phone, the phone receives corresponding call instructions.

[0179] Similar to the description in step 402, during the process of establishing a voice channel between the mobile phone and the operator's network through the network-side device, the network-side device sends signaling to the mobile phone to indicate the parameters necessary for establishing the voice channel. The mobile phone can obtain the first voice codec from the signaling.

[0180] Figure 7 The method shown involves the mobile phone selecting a wideband voice codec as the second voice codec and a narrowband voice codec as the first voice codec. Then, a voice path is established based on the narrowband voice codec. The Bluetooth headset uses the narrowband voice codec for voice data encoding and decoding, and the corresponding call algorithm is used to process the voice data at the other end. This solves the problem of mismatch between the call algorithm in the Bluetooth headset and the voice data bandwidth at the other end when the mobile phone is the calling end and the user initiates the voice call on the mobile phone side, due to the wideband voice codec being used for the second voice codec and the narrowband voice codec being used for the first voice codec. This effectively solves the problem of poor voice call quality.

[0181] Figure 8 The data processing method shown in the embodiment of this application is applicable to case two, and... Figure 6 The main difference between the methods shown is: Figure 6 Steps 602 to 604 in the method shown are replaced by the following steps 801 to 802, specifically:

[0182] Step 801: The mobile phone receives a call instruction, obtains the voice codec supported by the Bluetooth headset, determines the second voice codec based on the voice codec supported by the mobile phone and the Bluetooth headset, and establishes a voice channel with the Bluetooth headset based on the second voice codec.

[0183] When a user makes a call on their mobile phone, the phone receives corresponding call instructions.

[0184] In this step, the implementation of the mobile phone obtaining the voice codec supported by the Bluetooth headset and determining the second voice codec can be referred to the corresponding description in step 403. The implementation of the establishment of a voice path between the mobile phone and the Bluetooth headset based on the second voice codec can be referred to the corresponding description in step 407, which will not be repeated here.

[0185] Step 802: The mobile phone, as the calling end of the voice call, establishes a voice path with the operator's network through the network-side equipment and obtains the first voice codec.

[0186] The implementation of this step can be referred to the corresponding description in step 701, and will not be repeated here.

[0187] Figure 8 The method shown involves the mobile phone selecting a wideband voice codec as the second voice codec and a narrowband voice codec as the first voice codec. Then, it instructs the Bluetooth headset to switch call algorithms. This solves the problem of mismatch between the call algorithm in the Bluetooth headset and the other end's voice data bandwidth when the mobile phone is the calling end and the user initiates the call on the mobile phone side, provided that the second voice codec is wideband and the first is narrowband. This resolves the issue of poor voice call quality.

[0188] Different from Figure 6 and Figure 8 In the method shown, the mobile phone instructs the Bluetooth headset on the voice codec mode, and the Bluetooth headset switches the voice codec mode accordingly. In another data processing method provided in this application embodiment, the voice codec mode conversion is achieved by disconnecting the original voice path and establishing a new voice path. See also Figure 9A and Figure 9B As shown, respectively Figure 6 and Figure 8Steps 607-608 in the original text are replaced with step 901 below:

[0189] Step 901: The mobile phone disconnects the voice path between itself and the Bluetooth headset, and re-establishes the voice path between the mobile phone and the Bluetooth headset based on narrowband voice codec. The mobile phone and the Bluetooth headset respectively use narrowband voice codec to encode and decode the voice data between the mobile phone and the Bluetooth headset; the Bluetooth headset uses the call algorithm corresponding to the narrowband voice codec to process the decoded voice data.

[0190] Re-establishing the voice path between the mobile phone and Bluetooth headset based on narrowband voice codecs can include:

[0191] The mobile phone sends a channel establishment request message to the Bluetooth headset. The voice codec method carried in the channel establishment request message is narrowband voice codec.

[0192] In response to the channel establishment request message, the Bluetooth headset sends a channel establishment response message to the mobile phone.

[0193] By disconnecting and reconnecting the voice channel in step 901, the voice codec used in the Bluetooth headset is switched from wideband voice codec to narrowband voice codec. Consequently, the call algorithm used in the Bluetooth headset is switched from the call algorithm corresponding to wideband voice codec to the call algorithm corresponding to narrowband voice codec, thus realizing the switching of the call algorithm.

[0194] If the Bluetooth headset has a preset call algorithm, and preset parameters for narrowband voice codec and wideband voice codec for the call algorithm, the above call algorithm switching can be achieved by switching the parameters used by the preset call algorithm.

[0195] Figure 9A and Figure 9B The method shown selects a case where the second voice codec is wideband voice codec and the first voice codec is narrowband voice codec. Then, by disconnecting and re-establishing the voice path, the call algorithm in the Bluetooth headset is switched. This solves the problem of mismatch between the call algorithm in the Bluetooth headset and the voice data bandwidth of the other end when the second voice codec is wideband voice codec and the first voice codec is narrowband voice codec, thereby solving the problem of poor voice call quality.

[0196] Figure 10 This is a flowchart of one embodiment of the data processing method of this application, as shown below. Figure 10 As shown, the method may include:

[0197] Step 1001: The mobile phone and Bluetooth headset are successfully paired.

[0198] Step 1002: Establish a second voice channel between the mobile phone and the Bluetooth headset, and establish a first voice channel between the mobile phone and the network-side device.

[0199] The second voice codec method for establishing a second voice channel between the mobile phone and the Bluetooth headset can be determined based on the voice codec methods supported by the mobile phone and the Bluetooth headset; the mobile phone can act as the calling or called party in a voice call, and establish a first voice channel with the operator's network through network-side equipment; the voice call initiated by the mobile phone as the calling party can be initiated by the user operating on the mobile phone side or by the user operating on the Bluetooth headset side.

[0200] The above process for establishing the speech pathway can be implemented by referring to relevant methods, and will not be elaborated here.

[0201] Step 1003: The Bluetooth headset receives the voice signal from the other end of the voice call through the second voice channel mentioned above.

[0202] Step 1004: The Bluetooth headset calculates whether the spectral characteristics of each of the first number of voice frames in the voice signal are narrowband or wideband, and determines the first voice encoding / decoding method based on the spectral characteristics of the first number of voice frames.

[0203] The Bluetooth headset calculates whether the spectral characteristics of each speech frame in the first number of speech frames of the speech signal are narrowband or wideband, which may include:

[0204] The Bluetooth headset performs a Fourier transform (FFT) on the voice frame to convert the voice frame from a time domain signal to a frequency domain signal; it calculates the energy sum of the frequency domain signal between 5kHz and 8kHz in the voice frame's frequency domain signal, and determines that if the energy sum is less than a preset threshold, the spectral characteristics of the voice frame are narrowband; otherwise, the spectral characteristics of the voice frame are wideband.

[0205] Generally, Bluetooth headsets can take the first number of voice frames from the other end of a voice call, starting from the first voice frame, as the processing object in order to quickly determine the voice codec used between the mobile phone and the operator's network, and then determine whether to adjust the voice codec between the mobile phone and the Bluetooth headset.

[0206] The first quantity can be a natural number. If the first quantity is 1, calculating whether the spectral characteristics of a voice frame are narrowband or wideband, and determining whether the voice codec between the mobile phone and the network device is narrowband or wideband, may result in calculation errors. To improve accuracy, the spectral characteristics of more than one voice frame can be calculated. Accordingly, the Bluetooth headset can select the spectral characteristics that appear more frequently from the spectral characteristics of multiple voice frames to determine the voice codec between the mobile phone and the network device.

[0207] Step 1005: The Bluetooth headset determines whether the third voice codec is wideband voice codec. If it is, proceed to step 1006; otherwise, this branch of the process ends.

[0208] The third voice codec method is the voice codec method used in the second voice channel already established between the Bluetooth headset and the mobile phone.

[0209] If the judgment result is negative, it means that the third voice codec is a narrowband voice codec. In this case, the established second voice channel will continue to be used for the transmission of voice signals in the voice call, and the narrowband voice codec will be used for the encoding and decoding of the voice signals.

[0210] Step 1006: The Bluetooth headset determines whether the first voice codec is narrowband voice codec. If yes, proceed to step 1007; otherwise, this branch of the process ends.

[0211] If the result is negative, it means that the bandwidth between the mobile phone and the Bluetooth headset, and between the mobile phone and the network device, is broadband. In this case, the established voice channel will continue to be used for the transmission of voice signals during the voice call, and broadband voice codecs will be used for the encoding and decoding of voice signals during the voice call.

[0212] Step 1007: The Bluetooth headset uses the call algorithm corresponding to the narrowband voice codec to process the decoded voice data.

[0213] Figure 10 The method shown involves the Bluetooth headset determining the first voice codec based on the spectral characteristics of the voice frames in the peer's voice signal. Then, it selects a third voice codec that is wideband voice codec while the first voice codec is narrowband voice codec. The Bluetooth headset uses the call algorithm corresponding to the narrowband voice codec to process the decoded voice data. This solves the problem of bandwidth mismatch between the call algorithm in the Bluetooth headset and the peer's voice data when the third voice codec is wideband voice codec while the first voice codec is narrowband voice codec, thus resolving the issue of poor voice call quality.

[0214] Different from Figure 10 In the method shown, the Bluetooth headset switches the voice codec from wideband voice codec to narrowband voice codec. Figure 11 In the method shown, the conversion of the speech encoding and decoding method is achieved by disconnecting the original second speech path, re-negotiating the relevant parameters of the speech path, and establishing a new speech path. Specifically, steps 1007-1008 are replaced with the following step 1101:

[0215] Step 1101: The Bluetooth headset disconnects the second voice channel with the mobile phone, and re-establishes the voice channel between the mobile phone and the Bluetooth headset based on narrowband voice codec. The mobile phone and the Bluetooth headset respectively use narrowband voice codec to encode and decode the voice data between the mobile phone and the Bluetooth headset; the Bluetooth headset uses the call algorithm corresponding to the narrowband voice codec to process the decoded voice data.

[0216] In this process, the Bluetooth module typically disconnects the second voice channel between the Bluetooth headset and the mobile phone. Specifically, the audio module of the Bluetooth headset can send an instruction message to the Bluetooth module of the Bluetooth headset to instruct the Bluetooth module to disconnect the voice channel between the Bluetooth module and the mobile phone and re-establish the voice channel based on narrowband voice codec. The Bluetooth module then disconnects and re-establishes the voice channel according to the above instruction.

[0217] The process of re-establishing the voice path between the mobile phone and the Bluetooth headset based on narrowband voice codec can be referred to in step 901, which will not be repeated here.

[0218] Figure 11 The method shown involves the Bluetooth headset determining the first voice codec based on the spectral characteristics of the voice frames in the peer's voice signal. Then, it selects a case where the third voice codec is wideband voice codec while the first voice codec is narrowband voice codec. By re-establishing the voice path, the Bluetooth headset switches between voice codec methods, thereby enabling the switching of the call algorithm. This solves the problem of mismatch between the call algorithm and the peer's voice data bandwidth when the third voice codec is wideband and the first voice codec is narrowband, thus resolving the issue of poor voice call quality.
