Example 4:

The terminal system architecture provided by the foregoing embodiments of the present invention will be described in detail below in conjunction with specific specific application scenarios.

The following uses a 5G network as an example for description. An embodiment of the present invention provides a complete solution design of a terminal operating system. As shown in FIG. 5, the overall architecture of the solution of the present invention involves an end-to-end system connected to the transmission layer of a 5G network. At one end, the mobile phone terminal 51 runs a thin terminal operating system (that is, the terminal system architecture provided in the second embodiment above), and at one end is the server terminal 52 that runs the actual terminal operating system (that is, the terminal system architecture provided in the third embodiment above).

In this embodiment, a virtual HAL service is extended on the existing mobile phone system to replace the operating system based on CPU, GPU and other chips developed in the existing mobile phone, that is to say, such an alternative design method will make the mobile terminal 51 side The hardware resource requirements are relatively low, mainly to provide basic mobile phone peripherals such as screen, touch, buttons, speakers, microphone, camera, SIM card, 5G network module, etc. These peripherals can drive their basic SOC (system on chip ) Unified management of the system on chip, if necessary, can also provide the most basic EMMC, RAM and other SOC need extended storage and computing memory support.

The server 52 has high requirements on hardware resources. The hardware needs to provide CPU and GPU computing capabilities that can meet the requirements of mobile phones, and provide sufficient memory and storage space support.

The actual terminal operating system runs on the server side 52 and runs the actual mobile phone operating system. It can be compatible with different chips. For example, it can support the ARM64 or x86 platform. Because the actual terminal operating system does not have the hardware peripherals of the mobile phone, its purpose is to make the mobile phone operating system It can run seamlessly. The operating system needs to add a virtual hardware adaptation layer (HAL) to virtualize the peripherals of the thin terminal to the local through the network.

As shown in Figure 6, the actual terminal operating system is divided into an application layer, a framework layer, a HAL layer, a driver layer, and a hardware layer, where the HAL layer is divided into a real HAL layer and a virtual HAL layer.

The real HAL layer provides hardware interfaces that are not related to the terminal, such as storage devices such as audio, image engines such as GPU, bus management such as CPU, memory, clock, network access devices such as network cards, and so on.

The virtual HAL layer is an implementation of the HAL virtual layer that simulates thin terminal hardware. It mainly provides virtual HAL interfaces including: display output devices (LCD), touch screen or keyboard input devices, audio input and output devices (microphones and microphones), and communication devices (modems Data), multimedia equipment (camera), sensor equipment (gravity acceleration, gyroscope, geomagnetic sensor).

As shown in Figure 7, it is the overall structure of the thin terminal. The thin terminal OS itself can be transformed based on smart operating systems such as Android. The most basic requirement is that it needs to be able to initialize the hardware resources and kernel on the mobile phone side normally, and guide the terminal management application. And 5G virtual HAL service. On this basis, the 5G virtual HAL service is extended. This service provides the virtual HAL layer of the actual terminal operating system through the 5G network layer, provides a virtual file system node and IOCTL call interface, and can support operating systems like uevent. Callback mechanism.

As shown in Figure 8, after the thin terminal is started, the hardware driver is initialized. When the 5G virtual HAL service is started, it is necessary to detect which hardware interfaces are supported by the HAL layer on the mobile phone side and which can be shared with the remote actual operating system. The HAL service also An API interface is provided to the device management application. The device management application searches the connectable remote device through the API and connects. Based on the connection interface shown in FIG. 10, the specific startup steps may be as follows:

S801, start the Bootloader ARM boot program.

S802, Boot.img device driver initialization.

S803, the thin System.img system framework starts the peripheral service Daemon to run.

S804, the management application is started, and an available host is searched.

S805, connect the host and start the host.

S806, the peripheral service Daemon serves the virtual host.

After finding the remote actual operating system host, the connection process begins, the remote operating system starts, and it knows which virtual hardware the other party supports. After that, the driver of the real operating system will register the virtual device, and the application layer of the real operating system can be accessed. The virtual HAL layer, and then the virtual HAL layer will route all calls and send to the 5G virtual HAL service reception of the thin terminal through the 5G network, including the registration of the callback interface.

The callback is responsible for transmitting the feedback information of the hardware driver layer to the actual operating system. Once the callback registration from the actual operating system is received, the 5G virtual HAL service will save the callback token. When the time when the mobile terminal hardware meets the callback request occurs, Call the callback interface of the actual operating system remotely through the network to realize the transparent simulation of the HAL layer.

After receiving the request of the actual operating system, the 5G virtual HAL service will call the real HAL layer to communicate with peripherals through the HAL layer. These peripherals mainly include: display output device (LCD), touch screen or keyboard input device, audio input and output Equipment (microphone and microphone), communication equipment (modem data), multimedia equipment (camera), sensor equipment (gravity acceleration, gyroscope, geomagnetic sensor).

As shown in FIG. 9, the boot process of the host system of the actual operating system is started in conjunction with the thin terminal of FIG. 8. Generally speaking, the actual operating system host needs long-term power and network support. After booting, it enters the state of waiting for access, broadcasts its presence through the network, and performs handshake connection with the thin terminal through the necessary authentication process. The phase of waiting for connection only needs to be in a system that can initialize the 5G network, such as a bootloader or linux kernel. Once the connection is successful, the complete boot process begins. The virtual HAL and virtual driver layers are different from traditional operating systems (such as Android), as described above, after the transformation of the present invention, the virtual HAL can access the thin terminal hardware as hardware, and the specific startup steps can be as follows:

S901, Bootloader X86 boot program.

S902, initialize a 5G network card and generate a host node.

S903, waiting for the thin terminal to connect.

S904, connect the peripheral service of the thin terminal.

S905, load the full version of systemimage.

S906, load launcher/systemui and other applications.

Based on the above architecture, since there is no need to develop a specific operating system on the mobile phone terminal side, only some peripheral hardware circuits used by the user need to be provided. For this, the terminal system architecture provided by the embodiment of the present invention can also be flexibly based on actual use Combine application.

1. For example, if one card is designed to be used for multiple purposes, if a mobile phone card is connected to the host end of the actual operating system, multiple mobile phones can take one number.

2. If you don't want to use one card for multiple purposes, you can have one SIM card for each thin terminal, depending on which hardware is being virtualized.

3. One-to-multiple mode, the actual operating system of multiple home users can reuse the host, that is, the actual hardware of each host is also virtual, and multiple actual operating systems (similar to Android) are provided in the virtual machine. If it is based on a trusted foundation, multiple hosts can be switched at will, implementing multi-user measures similar to physical isolation, and providing AFW (Android For Work)-like functions.

4. Sharing is simpler: the hardware of the actual operating system host can provide a huge amount of data storage capacity of NTB, and it can be shared across the host, data calculation and resource downloading can be performed asynchronously, and shared to all hosts, and then It is equal to sharing to all users who use thin terminals.
