Example four:
the terminal system architecture provided by the above embodiment of the present invention is described in detail below with reference to specific application scenarios.
Taking a 5G network as an example for explanation, the embodiment of the present invention provides an overall scheme design of a set of terminal operating systems, as shown in fig. 5, in a general architecture of the scheme of the present invention, relating to an end-to-end system connected to a 5G network transport layer, one end of the system is a mobile phone terminal 51 running a thin terminal operating system (i.e., the terminal system architecture provided in the second embodiment), and the other end is a server end 52 running an actual terminal operating system (i.e., the terminal system architecture provided in the third embodiment).
In this embodiment, a virtual HAL service is extended from an existing mobile phone system to replace an operating system developed based on chips such as a CPU and a GPU in an existing mobile phone, that is, such a design replacement mode would make the hardware resource requirement on the mobile phone terminal 51 side lower, and mainly provides basic mobile phone peripherals such as a screen, a touch, a button, a speaker, a microphone, a camera, a SIM card, a 5G network module, etc., which are uniformly managed by a system on a chip (SOC) capable of driving them, and if necessary, may also provide the most basic storage and operation memory support required to be extended by SOCs such as an EMMC and a RAM, etc.
The server 52 has a high requirement on hardware resources, and needs to provide the CPU and GPU computing capabilities that can meet the requirements of the mobile phone, and provide sufficient memory and storage space support.
The actual terminal operating system runs on the server 52, runs the actual mobile phone operating system, and is compatible with different chips, such as an ARM64 or an x86 platform, because the actual terminal operating system does not have a hardware peripheral of a mobile phone, in order to enable the mobile phone operating system to run seamlessly, the operating system needs to add a virtual Hardware Adaptation Layer (HAL), and virtualizes the peripheral of the thin terminal to the local through a network.
As shown in fig. 6, the real terminal operating system is divided into an application layer, a framework layer, a HAL layer, a driver layer and a hardware layer, wherein the HAL layer is divided into a real HAL layer and a virtual HAL layer.
The real HAL layer provides hardware interfaces unrelated to the terminal, such as storage devices like audio, image engines like GPU, bus management like CPU, memory, clock, network access devices like network card, etc.
The virtual HAL layer is a HAL virtual layer implementation simulating thin terminal hardware, and mainly provides a virtual HAL interface comprising: display output devices (LCD), touch screen or keyboard input devices, audio input output devices (microphone and microphone), communication devices (modem data), multimedia devices (camera), sensor devices (acceleration of gravity, gyroscope, geomagnetic sensor).
As shown in fig. 7, the overall framework of the thin terminal is provided, the thin terminal OS itself may be modified based on an intelligent operating system such as android, and the most basic requirements are that hardware resources and kernels on the mobile phone side need to be initialized normally, and the terminal management application and the 5G virtual HAL service are guided. On the basis, 5G virtual HAL service is expanded, the service provides service for the virtual HAL layer of the actual terminal operating system through a 5G network layer, provides a virtual file system node and an IOCTL calling interface, and can support operating system callback mechanisms like uevent and the like.
As shown in fig. 8, after the thin terminal is started, the hardware driver is initialized, when the 5G virtual HAL service is started, it needs to detect which hardware interfaces are supported by the HAL layer on the mobile phone side, which hardware interfaces can be shared to the remote real operating system, the HAL service also provides an API interface to the device management application, the device management application searches for connectable remote devices through the API, and connects the connectable remote devices, based on the connection interface shown in fig. 10, the specific starting steps may be as follows:
s801, starting a Bootloader ARM bootstrap program.
And S802, initializing boot.
And S803, starting the peripheral service Daemon by the thin System.
S804, the management application is started to search for available hosts.
S805, connecting the host and starting the host.
And S806, serving the virtual host by using the peripheral service Daemon.
After finding the remote actual operating system host, the connection process starts, the remote operating system starts to start, and knows which virtual hardware is supported by the other side, then the driver of the real operating system registers the virtual equipment, the application layer of the real operating system can access the virtual HAL layer, then the virtual HAL layer routes all calls, and the calls are sent to the 5G virtual HAL service reception of the thin terminal through the 5G network, including the registration of the callback interface and the like.
The callback is responsible for transmitting feedback information of the hardware driving layer to the actual operating system, once callback registration from the actual operating system is received, the 5G virtual HAL service can store a callback token, and after the occasion that the mobile phone terminal hardware meets the callback requirement occurs, the callback interface of the actual operating system is remotely called through a network, so that transparent simulation of the HAL layer is realized.
After receiving the request of the actual operating system, the 5G virtual HAL service will call the real HAL layer, and communicate with the peripherals through the HAL layer, and these peripherals mainly include: display output devices (LCD), touch screen or keyboard input devices, audio input output devices (microphone and microphone), communication devices (modem data), multimedia devices (camera), sensor devices (acceleration of gravity, gyroscope, geomagnetic sensor).
As shown in fig. 9, the host system boot process of the real operating system is initiated in conjunction with the thin terminal of fig. 8. Generally, an actual operating system host needs to be supported by a power supply and a network for a long time, enters a state of waiting for access after being started, broadcasts the existence of the host to the outside through the network, and performs handshake connection with a thin terminal through a necessary authentication process. In the connection waiting stage, as long as in a system capable of initializing a 5G network, such as a bootloader or linux kernel, once the connection is successful, a complete boot process is started, where the virtual HAL and the virtual driver layer are different from the conventional operating system (such as Android), which is introduced above, after the transformation of the present invention, the virtual HAL may access the thin terminal hardware as hardware, and the specific starting steps may be as follows:
s901, Bootloader X86 boots the program.
S902, initializing the 5G network card and generating a host node.
And S903, waiting for connection of the thin terminal.
And S904, connecting the thin terminal peripheral service.
S905, the complete version systemimage is loaded.
S906, loading launchers/systemui and other applications.

1. For example, one card is designed to be used for multiple purposes, and if one mobile phone card is connected to a host end of an actual operating system, a plurality of mobile phones can take one number.
2. If one card is not desired to be multi-purpose, there may be one sim card per thin terminal, depending on which hardware is virtualized.
3. In one-to-many mode, the actual operating systems of multiple home users can multiplex the hosts, that is, the hardware actually run by each host is also virtual, and multiple actual operating systems (similar to Android) are provided in the virtual machines. If the system is based on a credible basis, a plurality of hosts can be switched at will, multi-user measures similar to physical isolation are realized, and functions similar to AFW (android For work) can be provided.
