Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a wake-up signal is used to manage terminal power states, then power saving is improved, but false wake-ups occur leading to reduced reliability
Solution Approach 1:
The patent segments terminals into different groups based on their wake-up behavior characteristics. By dividing the terminal population into groups with similar paging patterns and wake-up probabilities, the system can apply group-specific wake-up signals and parameters, thereby reducing false wake-ups while maintaining power saving benefits.
Solution Approach 2:
The patent changes parameters such as wake-up signal thresholds, paging occasions, and group-specific configuration parameters based on terminal behavior patterns. By dynamically adjusting these parameters for different terminal groups, the system optimizes the balance between power saving and reliability, reducing false wake-ups while maintaining energy efficiency.
2Loss of information
If group wake-up signals are implemented to reduce signaling overhead, then signaling efficiency is improved, but terminal grouping complexity increases
Solution Approach 1:
The patent segments terminals into groups based on measurable characteristics such as paging patterns, activity levels, and service types. This segmentation enables the network to apply group-specific wake-up signals and configurations, reducing overall signaling overhead while keeping the grouping logic based on readily available terminal attributes.
Solution Approach 2:
The patent enables terminals to self-identify with appropriate groups based on their service requirements and behavior patterns. Terminals can autonomously determine their group membership based on configured criteria, reducing the need for complex network-controlled grouping mechanisms and simplifying the overall system complexity.
3Reliability
If handover information reporting is enhanced to improve mobility management, then network performance is improved, but signaling overhead increases
Solution Approach 1:
The patent implements partial reporting of handover information based on event triggers and network needs. Instead of continuously reporting all handover parameters, the system reports only relevant information when specific events occur (e.g., handover execution, failure conditions), thereby maintaining mobility management quality while reducing signaling overhead.
Solution Approach 2:
The patent dynamically changes reporting parameters such as reporting intervals, triggered events, and information granularity based on terminal mobility patterns and network conditions. By adapting these parameters, the system optimizes the balance between mobility management effectiveness and signaling overhead reduction.
