Solution Overview
Problem
In wireless communication systems, especially in IoT environments, there is a need to minimize battery consumption and effectively manage battery life in IoT devices, as existing solutions do not adequately control operation mode durations to optimize power usage.
Innovation Solution
A server-based method and apparatus that receives information on battery state and operation mode durations from IoT devices, determines optimized time durations for minimizing battery consumption, and transmits these settings to adjust operation modes such as eDRX and PSM durations, thereby reducing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operation mode duration is extended to ensure reliable communication, then communication reliability is improved, but battery consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of operation mode durations based on real-time battery state monitoring. The server receives battery state information from IoT devices and dynamically determines optimized time durations for operation modes like eDRX and PSM, allowing the system to adapt communication reliability and power consumption to current battery conditions rather than using fixed durations
Solution Approach 2:
The patent changes the parameter of operation mode duration based on battery state. By receiving battery state information and determining optimized time durations, the system modifies the duration parameter dynamically - extending it when battery is healthy to improve reliability, and shortening it when battery is low to conserve energy, thus resolving the contradiction between reliability and power consumption
2Use of energy by moving object
If operation mode duration is shortened to reduce battery consumption, then power efficiency is improved, but communication reliability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where IoT devices transmit battery state information to the server, which then determines optimized operation mode durations and sends control instructions back to the devices. This closed-loop feedback system ensures that communication reliability is maintained by adjusting durations based on actual battery conditions, preventing the reliability deterioration that would occur with fixed short durations
3Device complexity
If fixed operation mode durations are used to simplify system design, then device complexity is reduced, but adaptability to battery conditions deteriorates
Solution Approach 1:
The patent introduces a server as an intermediary that handles the complex task of determining optimized operation mode durations. Instead of embedding complex adaptation logic in each IoT device, the server receives battery state information from multiple devices, determines appropriate durations, and sends control instructions back, thus reducing device complexity while maintaining high adaptability to battery conditions
