[0058] Figure 7It is a schematic diagram of the flow of voice call data when making a voice call through other electronic devices provided in an embodiment of the present application.

[0059] exist Figure 7 In the example, electronic device A cannot communicate directly with the satellite, but electronic device B can communicate directly with the satellite. When electronic device A wants to initiate a satellite call, it uses electronic device B to complete the voice call data flow.

[0060] First, electronic device A and electronic device B establish a connection through mutual transmission to transmit information. The application processor (AP) side of electronic device A sends a satellite call establishment request to the AP side of electronic device B through the mutual transmission connection. The request includes the identification information of the electronic device that electronic device A expects to make a satellite call with, for example, the identification information is the telephone number of the electronic device. The AP side of electronic device B receives the satellite call request, establishes short-range communication with electronic device A through the Bluetooth chip, and establishes a satellite call connection with the satellite at the same time.

[0061] When electronic device A sends voice call data, the microphone of electronic device A collects voice and sends the collected voice data to the codec of electronic device A; the codec of electronic device A performs data conversion on the voice call data and sends the converted voice call data to the audio digital signal processing subsystem of electronic device A; the audio digital signal processing subsystem of electronic device A performs noise reduction and echo cancellation on the received voice call data; and sends the voice call data after echo cancellation and noise reduction to the Bluetooth chip of electronic device A.

After receiving the voice call data, the Bluetooth chip of electronic device B sends it to the audio digital signal processing subsystem of electronic device B, and the audio digital signal processing subsystem of electronic device B sends the voice call data to the satellite chip of electronic device B, and the satellite chip of electronic device B sends the voice call data to the satellite, and then the satellite sends the voice call data to the electronic device with which electronic device A wishes to make a satellite call.

[0062] The flow of voice call data when electronic device A sends voice call data is as follows:

[0063] Microphone of electronic device A -> codec of electronic device A -> audio digital signal processing subsystem of electronic device A -> Bluetooth chip of electronic device A -> Bluetooth chip of electronic device B -> audio digital signal processing subsystem of electronic device B -> satellite chip of electronic device B -> satellite.

The Bluetooth chip of electronic device B and the Bluetooth chip of electronic device A transmit the voice call data through the air. After receiving the voice call data, the Bluetooth chip of electronic device A sends it to the audio digital signal processing subsystem of electronic device A, and the audio digital signal processing subsystem of electronic device A performs noise reduction processing on the voice call data, and sends the voice call data after the noise reduction processing to the codec of electronic device A, and the codec of electronic device A performs data conversion on the voice call data, and sends the voice call data after the data conversion to the playback device of electronic device A for playback.

[0065] Satellite -> Satellite chip of electronic device B -> Audio digital signal processing subsystem of electronic device B -> Bluetooth chip of electronic device B -> Bluetooth chip of electronic device A -> Audio digital signal processing subsystem of electronic device A -> Codec of electronic device A -> Playback device of electronic device A.

[0066] In an embodiment of the present application, when an electronic device cannot communicate directly with a satellite, satellite calls can be made through other electronic devices, which can solve the need for satellite calls when a satellite cannot be connected in certain circumstances.

[0067] In some possible implementations of the embodiments of the present application, the voice call data sent by the satellite chip to the audio digital signal processing subsystem can be recorded, and the voice call data sent by the audio digital signal processing subsystem to the satellite chip can also be recorded, that is, when receiving voice call data, the voice call data that has not been processed by noise reduction is recorded, and when sending voice call data, the voice call data that has been processed by noise reduction and echo cancellation is recorded.

[0068] The following uses an electronic device equipped with a Qualcomm platform as an example to illustrate the satellite call process. Figure 8 It is a schematic diagram of controlling a satellite communication path provided in an embodiment of the present application.

[0069] exist Figure 8In the present invention, a user initiates a satellite call through a call program in the application layer, and a satellite call request is sent to the hardware abstraction layer through the framework layer; the audio hardware abstraction layer in the hardware abstraction layer initiates the establishment of a satellite call channel, and the customized interface layer in the hardware abstraction layer sets the parameters of the voice call channel composed of the satellite chip, the audio digital signal processing subsystem and the codec and opens the voice call channel. The parameters of the voice call channel include but are not limited to sampling rate, bit width and channel, etc. The way to open the voice call channel can be to set the parameter SetSatelliteCall value to 1, wherein when SetSatelliteCall is 1, it indicates that the voice call channel composed of the satellite chip, the audio digital signal processing subsystem and the codec is opened; the Qualcomm hardware abstraction layer in the hardware abstraction layer sets the parameters of the codec, loads the preset channel information and algorithm parameter information, etc., sends the channel information and algorithm parameter information, etc. to the audio digital signal processing subsystem, and then wakes up the audio digital signal processing subsystem and opens the codec. After the audio digital signal processing subsystem is woken up, the sound transmission and algorithm processing are turned on, and the codec converts the voice call data.

[0070] When the satellite chip receives voice call data sent by the satellite through the antenna, the satellite chip sends the received voice call data to the audio digital signal processing subsystem, the audio digital signal processing subsystem processes the received voice call data, and sends the processed voice call data to the codec, the codec converts the received voice call data, and then sends the voice call data obtained after the data conversion to the playback device for playback.

[0071] When the codec receives the voice call data sent by the sound collection device, it converts the data and sends the converted voice call data to the audio digital signal processing subsystem. The audio digital signal processing subsystem processes the received voice call data and sends the processed voice call data to the satellite chip. The satellite chip sends the received voice call data to the satellite via the antenna.

[0072] When the electronic device cannot communicate with the satellite through the satellite chip, the audio hardware abstraction layer initiates the satellite call path switching, and the customized interface layer switches the voice call path to the voice call path composed of the Bluetooth chip, the audio digital signal processing subsystem and the codec. The way to switch the voice call path is to set the parameter SetSatelliteCall value to 2, wherein when SetSatelliteCall is 2, it means that the voice call path is switched to the voice call composed of the Bluetooth chip, the audio digital signal processing subsystem and the codec. The Qualcomm hardware abstraction layer closes the current path and opens the switched path.

[0073] When sending voice call data, the codec converts the voice call data sent by the sound collection device, and sends the voice call data obtained after the data conversion to the audio digital signal processing subsystem. The audio digital signal processing subsystem processes the received voice call data and sends the processed voice call data to other electronic devices through the Bluetooth chip. The other electronic devices send the voice call data to the satellite.

[0074] When receiving voice call data, the voice call data sent by other electronic devices is received through the Bluetooth chip, and the Bluetooth chip sends the received voice call data to the audio digital signal processing subsystem. The audio digital signal processing subsystem processes the received voice call data and sends the processed voice call data to the codec. The codec converts the received voice call data and then sends the converted voice call data to the playback device for playback.

[0075] When the user initiates a call closing through the call program of the application layer, the call closing request is sent to the hardware abstraction layer through the framework layer; the audio hardware abstraction layer in the hardware abstraction layer initiates the satellite call channel closing, and the customized interface layer in the hardware abstraction layer sets the voice call channel closing. The way to close the voice call channel is to set the parameter SetSatelliteCall value to 0, where SetSatelliteCall is 0, which means closing the voice call channel; the Qualcomm hardware abstraction layer in the hardware abstraction layer closes the codec and notifies the audio digital signal processing subsystem to clear the channel information; the audio digital signal processing subsystem closes the sound transmission and algorithm processing, and then goes into sleep mode, and the codec stops data conversion.

[0076] Based on the satellite call system provided in the embodiment of the present application, the embodiment of the present application provides a satellite call method, which is applied to the satellite call method provided in the embodiment of the present application.

[0080] Step 903: The codec performs data conversion on the second voice call data to obtain third voice call data, and sends the third voice call data to the audio device.

[0081] In some possible implementations of the embodiments of the present application, the satellite call method provided in the embodiments of the present application further includes:

[0082] When the codec receives the fourth voice call data sent by the audio device, the codec performs data conversion on the fourth voice call data to obtain fifth call data, and sends the fifth voice call data to the audio digital signal processing subsystem;
