Description

Technical Field

[0001] The present invention relates to the technical field of dual-mode telephone communication, and in particular to a method and device for realizing audio communication of a dual-mode telephone in PSTN mode and IP mode through a Bluetooth voice device. Background Art

[0002] Dual-mode phones support calls in PSTN mode and IP mode, and need to process two different audio sources: PSTN analog audio stream and VoIP digital audio stream. Therefore, the PSTN mode and IP mode calls of traditional dual-mode phones are realized through their own audio channels. Among them, PSTN mode calls are realized by connecting the analog phone chip directly to the telephone line, and there is only analog audio stream in this audio channel; IP mode calls are realized by connecting the sound card to the digital audio object (audio track AudioTrack and recording tool AudioRecorder) of the framework layer. There is only digital audio stream in this audio channel, and the two audio channels are independent of each other. The Bluetooth module only supports digital voice. When a Bluetooth voice device (such as a Bluetooth headset) is connected and IP mode calls are made, the Bluetooth voice device is connected to the Bluetooth module of the dual-mode phone, and the digital audio object of the framework layer is connected to the Bluetooth module to realize voice calls through the Bluetooth voice device. When calling in PSTN mode, the output of the analog phone chip is an analog audio stream, which cannot interact with the audio stream of the Bluetooth module, so it is impossible to make voice calls through the Bluetooth voice device.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] like Figure 1 As shown, the embodiment of the present application provides a method for a dual-mode phone to realize audio communication through a Bluetooth voice device, the method comprising the following steps: Step S100, connect the sound card codec of the dual-mode phone to the analog phone chip, and define a new call mode according to the original call mode (IP mode and PSTN mode) of the framework layer and the Bluetooth module of the dual-mode phone connected to the Bluetooth voice device; since the analog phone chip of the traditional dual-mode phone is an analog signal and cannot perform wireless transmission of analog signals, the analog phone chip and the sound card codec are connected by a physical data line. In the embodiment of the present application, the new call mode at least includes audio communication in IP mode, audio communication in IP Bluetooth mode that realizes audio communication through Bluetooth voice equipment in IP mode, audio communication in PSTN mode, and audio communication in PSTN Bluetooth mode that realizes audio communication through Bluetooth voice equipment in PSTN mode; in some embodiments, audio communication in IP mode in the call mode includes a first hands-free mode and a first handle mode; audio communication in PSTN mode includes a second hands-free mode and a second handle mode.

[0017] Step S200: configuring an audio path in each new call mode for the audio routing module in the hardware abstraction layer HAL; wherein configuring an audio path in each new call mode for the audio routing module in the hardware abstraction layer HAL includes: The audio path is configured for the first hands-free mode. Specifically, the configuration is as follows: the default voice mode of the dual-mode telephone system is switched, that is, the framework layer video object establishes a connection with the sound card codec, the interface connecting the sound card codec with the speaker and microphone of the host of the dual-mode telephone (the connection is a physical line connection) is available, and the interface connecting the sound card codec with the analog telephone chip is unavailable; Configure the audio path for the first handle mode. Specifically, the framework layer audio object establishes a connection with the sound card codec, and switches the speaker and microphone corresponding to the dual-mode phone handle to the sound card codec. The interface connecting the sound card codec with the analog phone chip is unavailable; the interface connecting the sound card codec with the speaker and microphone of the host of the dual-mode phone is unavailable. Configure the audio path for the IP Bluetooth mode. Specifically, the configuration is to establish a connection between the framework layer audio object and the Bluetooth module BT. The interface connecting the sound card codec and the analog phone chip is unavailable; the interface connecting the sound card codec and the speaker and microphone of the host of the dual-mode phone is unavailable; The audio path is configured for the second hands-free mode, specifically, the interface connecting the sound card codec and the analog phone chip is available; the interface connecting the sound card codec and the speaker and microphone of the host of the dual-mode phone is available; Configure the audio path for the second handle mode. Specifically, the speaker and microphone corresponding to the dual-mode phone handle are switched to the analog phone chip. The interface connecting the sound card codec and the analog phone chip is unavailable. The interface connecting the sound card codec and the speaker and microphone of the dual-mode phone host is unavailable. Configure the audio path for the PSTN Bluetooth mode. Specifically, the sound card codec establishes a connection with the Bluetooth module BT. The interface connecting the sound card codec to the analog phone chip is available, and the interface connecting the sound card codec to the speaker and microphone of the host of the dual-mode phone is unavailable.

[0018] Step S300, the framework layer of the dual-mode phone sends the new call mode selected by the application layer to the hardware abstraction layer HAL, and the audio routing module in the hardware abstraction layer HAL finds the configured audio path according to the received new call mode, switches the audio path according to the configured audio path, and performs audio communication through the switched audio path.

[0019] In step S300 of the embodiment of the present application, the steps of performing audio communication through the switched audio path are specifically as follows: When the switched audio path is the audio path configured for the first hands-free mode, the framework layer audio object outputs a digital audio stream (VoIP digital audio stream) to the sound card, and the sound card forwards the digital audio stream to the host speaker connected to the sound card; correspondingly, the host's microphone sends the acquired audio stream to the sound card, and the sound card sends the digital audio stream to the audio object of the framework layer.

[0020] When the switched audio path is the audio path configured for the first handle mode, the framework layer audio object outputs the digital audio stream to the sound card, and the sound card forwards the digital audio stream to the speaker corresponding to the dual-mode phone handle; correspondingly, the microphone corresponding to the dual-mode phone handle sends the acquired audio stream to the sound card, and the sound card sends the digital audio stream to the audio object of the framework layer.

[0021] When the switched audio path is configured for the IP Bluetooth mode, the framework layer audio object outputs a digital audio stream to the Bluetooth module BT, and the Bluetooth module forwards the digital audio stream to the speaker of the Bluetooth voice device; correspondingly, the microphone corresponding to the Bluetooth voice device sends the acquired audio stream to the Bluetooth module BT, and the Bluetooth module BT sends the digital audio stream to the audio object of the framework layer.

[0022] When the switched audio path is the audio path configured for the second hands-free mode, the analog phone chip outputs an analog audio stream to the sound card, and the sound card forwards the analog audio stream to the host speaker connected to the sound card; correspondingly, the host's microphone sends the acquired audio stream to the sound card, and the sound card sends the audio stream to the analog phone chip.

[0023] When the switched audio path is the audio path configured for the second handle mode, the analog phone chip sends the analog audio stream to the speaker corresponding to the dual-mode phone handle; correspondingly, the microphone corresponding to the dual-mode phone handle sends the acquired audio stream to the analog phone chip.

[0024] When the switched audio path is configured for the PSTN Bluetooth mode, the analog phone chip sends the analog audio stream to the sound card codec, the sound card codec performs analog-to-digital conversion on the analog audio stream and sends it to the Bluetooth module BT, which is forwarded by the Bluetooth module BT to the speaker of the Bluetooth voice device; correspondingly, the audio obtained by the microphone of the Bluetooth voice device is forwarded by the Bluetooth module BT to the sound card codec, the sound card codec performs digital-to-analog conversion on the digital audio stream and sends it to the analog phone chip for processing.

[0025] The embodiment of the present application redefines the call mode of the dual-mode phone based on the access status of the Bluetooth voice device and configures the corresponding audio path for each new call mode in the audio routing module. The audio routing module switches the audio path according to the new call mode, thereby controlling whether the audio object connected to the Bluetooth module is the audio object of the default framework layer of the dual-mode phone system or the analog phone chip, thereby realizing free switching of the Bluetooth voice stream between two channel audio streams (digital audio stream and analog audio stream), solving the problem that the Bluetooth voice device connected to the dual-mode phone cannot work in the PSTN mode, and making the Bluetooth voice device connected to the dual-mode phone compatible with processing audio of both analog and digital signal sources, expanding the applicable scenarios of traditional dual-mode phones, not only improving the user experience, but more importantly saving the cost of equipment replacement for users.

[0026] Bluetooth voice devices have delays, and the IP phone itself may also introduce delays due to network conditions, especially in PSTN Bluetooth mode, which requires conversion between analog and digital. When the delay accumulates too much, it will not only lead to a decline in call experience, but more importantly, for call applications with high requirements for real-time interaction, in some embodiments of the present application, in order to solve the delay problem, a low-latency Bluetooth protocol (Bluetooth Low Energy Audio) is applied. Except for the second hands-free mode and the second handle mode, IP calls in other modes use a high compression ratio codec algorithm (SBC) to reduce the delay of audio transmission; at the hardware level, a Bluetooth module that supports faster processing capabilities is used to reduce delays, and communication between PSTN voice and Bluetooth voice devices is achieved with a smaller delay (20ms), so that there is no obvious delay in audio communication in IP Bluetooth mode and PSTN Bluetooth mode.
