Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of operating systems, and particularly relates to an embedded office operating system suitable for low-carbon mobile terminals. BACKGROUND

[0002] With the deep penetration of mobile Internet and the popularity of 5G technology, mobile terminals (such as smart phones, tablet computers, thin and light notebooks, etc.) have become the core tool for modern people to remotely collaborate, process documents, manage tasks, communicate at meetings, and other daily office scenarios, especially after the popularity of flexible office mode, its office attribute demand is further highlighted. However, the current mainstream mobile operating system is designed with entertainment and basic communication functions as the core, focusing on scene optimization such as video and audio playback, social chatting, game interaction, etc., and there are obvious short boards in aspects such as multi-task collaboration efficiency, professional document format compatibility, cross-device data synchronization stability, etc. in the office scene, which is difficult to match the efficient office demand. In addition, the "double carbon" target promotion and the popularity of green office concept make the energy consumption problem of mobile terminals more critical - in the long-term office scenario, high power consumption of devices not only shortens the battery life of mobile devices, which cannot support all-day office; the carbon emissions generated during operation are also contrary to the needs of enterprise low-carbon operation and personal green office.

[0003] At present, most of the mobile office applications on the market are developed based on existing operating systems, which have the following problems:

[0004] 1. Low efficiency of power consumption management and control: the existing mobile operating system lacks a hardware resource dynamic scheduling mechanism for office scenarios when running office applications. For example, in high-frequency operations such as simultaneous editing of multiple documents and real-time synchronization of cloud data, the CPU is often in a high occupancy state, and the memory frequently exchanges data, resulting in high power consumption of the device, short battery life, and the need for frequent charging, which affects the continuity of mobile office.

[0005] 2. Redundant and bloated office components: The installation package size of mainstream office components (such as word processing and spreadsheet analysis software) generally reaches 500MB-1.2GB, which not only occupies the limited storage space of mobile terminals, but also increases the application startup time and occupies a large amount of system memory during running, which is easy to cause lag and crash.

[0006] 3. Strong dependence on network: Most mobile office applications need to rely on the network to run normally and cannot perform office operations in offline situations, which brings inconvenience to users.
