Shutdown State Reminder Execution Without Full OS Boot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reminder systems in mobile terminals consume significant time and energy by loading the complete operating system to remind users, which is inefficient and wasteful, especially when the terminal is in a shutdown state.
Innovation Solution
A method and device that receive a wakeup instruction from a clock circuit in a shutdown state, execute a preset initialization operation without starting the operating system, and execute a preset reminding program stored independently of the operating system to remind the user, allowing reminders to be triggered without fully powering up the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the complete operating system is loaded to perform reminding after shutdown, then the reminding function can be executed, but the time consumption and energy consumption increase significantly
Solution Approach 1:
The patent segments the reminding function from the complete operating system, creating an independent reminder execution mechanism that operates without requiring full system initialization. The reminder program is separated and can run in a minimal system environment, dividing the traditional monolithic startup process into essential initialization and optional full system loading stages.
Solution Approach 2:
The patent applies partial action by loading only the necessary components for reminder execution rather than the complete operating system. The system performs just enough initialization to run the reminder program, avoiding unnecessary loading of other system modules, thus reducing time and energy consumption while still achieving the reminding function.
2Reliability
If the complete operating system is loaded to perform reminding after shutdown, then the reminding function can be executed, but the energy consumption increases
Solution Approach 1:
The patent segments the reminding function from the complete operating system, creating an independent reminder execution mechanism that operates without requiring full system initialization. This separation allows the system to consume only the minimal energy required for reminder execution rather than powering up all system components.
Solution Approach 2:
The patent applies partial action by loading only the necessary components for reminder execution rather than the complete operating system. The system performs just enough initialization to run the reminder program, avoiding unnecessary energy consumption from loading and running unrelated system modules.
3Adaptability or versatility
If the operating system is started to execute reminder events, then all system functions are available, but the device complexity and startup time increase
Solution Approach 1:
The patent segments the reminding function from other system functions, allowing the reminder program to execute independently with minimal system initialization. This segmentation enables the system to maintain simplicity for basic reminder operations while preserving full system functionality when needed, reducing unnecessary complexity.

AI summary
The present disclosure relates to a method and a device for reminding in a shutdown state. The method includes: receiving a wakeup instruction from a clock circuit in a shutdown state; executing a preset initialization operation according to the wakeup instruction, in which the preset initialization operation does not comprise starting an operating system; and executing a preset reminding program according to a pre-stored reminder event after the preset initialization operation is completed. With the method provided in the present disclosure, the reminder event may still be reminded of even if the operating system is not started, a time-consuming problem and an electricity-consuming problem caused by starting the operating system may be avoided, the electric energy may be saved, and meanwhile a call function will not be started, a radiofrequency radiation may be prevented, and the user experience is improved.
