Detailed ways

Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and they should be regarded as exemplary only. 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 disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Generally, the hardware architecture of mobile devices such as mobile phones and tablet computers is composed of two processors. One processor is used to run the operating system on which the application program is run. This processor is called the Application Processor (Application Processor, AP); The device runs 2G, 3G, 4G, 5G protocol stack programs to realize functions related to radio frequency wireless communication, which is called baseband processor (Baseband Processor, BP). Taking the Android operating system as an example, the operating system and applications run on the AP, and realize the business logic of the voice call function through command interaction with the modem in the BP.

The operating system needs to rely on the modem driver to realize command interaction with the modem, but Modem manufacturers usually do not provide BP support under the Linux operating system, resulting in the inability of the Linux operating system to realize data communication with the modem and cannot support voice call services.

In the following embodiments, the applicant illustrates the technical problems to be solved by the embodiments of the present invention by taking the Linux operating system calling the Modem driver of the Android operating system as an example. Those skilled in the art can understand that in similar application scenarios, as long as the cross-system driver call implemented by the containerized operating system implemented by sharing the operating system kernel is applicable to the method of the embodiment of the present invention.

For example, the first operating system serving as the host and the second operating system deployed in the first operating system share a Linux kernel, which is realized by technologies such as LXC and containerization.

For example, the first operating system may be a GNU/Linux distribution, such as Ubuntu, Debian, RedHat, etc. It should be noted that the first operating system is not limited to running on a physical machine, and may also be an operating system hosted on another operating system, such as WSL in a Windows system.

For example, the second operating system may be an Android (Android) operating system, covering Android OS issued by Google, AOSP and various derivative systems based on AOSP, such as MIUI, EMUI, One UI, etc.

As known to those skilled in the art, there are many other mobile operating systems based on Linux Kernel that are used for mobile phones and other devices that natively support modems, such as Tizen, Hongmeng, Meego, etc., as examples of the second operating system, which are also applicable In the technical scheme of the embodiment of the present invention.

In the following embodiments, the hardware abstraction layer HAL encapsulates the operating system kernel driver, provides hardware access interfaces for various application layer requirements upwards, and shields the driver implementation details of the underlying hardware downwards.

In the following embodiments, the hardware abstraction layer interface description language, also known as the hardware abstraction layer interface definition language, is a language specification used to describe software component interfaces, so that software components (written in different languages) communicate with each other.
