Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Generally, a hardware architecture of a mobile device such as a mobile phone and a tablet computer is composed of two processors, one Processor is used for running an operating system and running an Application program thereon, and the Processor is called an Application Processor (AP); the other Processor runs 2G, 3G, 4G and 5G protocol stack programs to realize functions related to radio frequency wireless communication, and is called a Baseband Processor (BP). Taking the Android operating system as an example, the operating system and the application program run on the AP, and implement the service logic of the voice call function through command interaction with the modem in the BP.
The operating system needs to realize command interaction with the Modem by depending on the drive of the Modem, but a Modem manufacturer usually does not provide the support of the BP under the Linux operating system, so that the Linux operating system cannot realize data communication with the Modem and cannot support voice call service.
In the following embodiments, the applicant takes the Linux operating system to call the Modem driver of the Android operating system as an example to describe the technical problem to be solved by the embodiments of the present invention. Those skilled in the art can understand that similar application scenarios, as long as the cross-system driver call implemented in the containerized operating system implemented in the shared operating system kernel, are applicable to the method of the embodiments of the present invention.
For example, the first operating system as a host and the second operating system deployed in the first operating system are shared Linux kernels, and are implemented by LXC, containerization, and other technologies.
For example, the first operating system may be a GNU/Linux release, such as Ubuntu, debian, redHat, or the like. It should be noted that the first operating system is not limited to be running on a physical machine, and may also be an operating system hosted on another operating system, for example, WSL in a Windows system.
For example, the second operating system may be an Android operating system, encompassing the Android OS issued by Google and AOSP and various derivative systems based on AOSP, such as MIUI, EMUI, one UI, and the like.
As known to those skilled in the art, there are various other Linux Kernel-based mobile operating systems for native Modem-supported modems on devices such as mobile phones, such as Tizen, hong meng, meego, etc. as examples of the second operating system, which are also applicable to the technical solution of the embodiments of the present invention.
In the following embodiments, the hardware abstraction layer HAL encapsulates the kernel driver of the operating system, provides a hardware access interface to various application layer requirements, and shields the driver implementation details of the underlying hardware downwards.

After the registration is finished, the communication between the transmission channel process of the Linux operating system and the Android Modem HAL can be realized through the Hwbinder service.

taking the first operating system as a Linux operating system and the second operating system as an Android operating system as an example, the audio device of the Linux operating system is called through the telephone service of the Linux framework layer, and the audio data transmission channel is opened for inputting and outputting audio data.
Because the Linux operating system cannot directly communicate with the modem, the Android modem HAL is used as a relay to send the instruction data to a Rild process of a radio frequency interface layer of the Android modem HAL, and the Rild process is an application process which can be used for the Android modem HAL to communicate with the modem.
And step S103, sending the instruction data to the modem through the modulation and demodulation hardware abstraction layer so that the modem establishes a voice channel according to the instruction data.
