Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations perform manual adjustment of mobility control parameters through extensive outdoor tests and data collection, then the balance between link connection failure rate and ping-pong handover rate can be optimized, but the process is inefficient and cannot automatically adapt to changing terminal and cell conditions
Solution Approach 1:
The patent implements a feedback mechanism where the terminal reports its moving state to the base station, and the base station adjusts mobility control parameters accordingly. This closed-loop feedback system enables automatic adaptation to changing conditions without requiring extensive manual testing, resolving the contradiction between optimization effectiveness and automation extent.
Solution Approach 2:
The terminal autonomously detects its own moving state and initiates the parameter adjustment process by reporting to the base station. This self-service capability eliminates the need for manual intervention in parameter optimization, allowing the system to automatically adapt to changing terminal and cell conditions.
2Manufacturing precision
If base stations conduct extensive outdoor tests and data collection to determine control parameter values, then proper parameter values can be established, but the process is time-consuming and cannot keep up with dynamic network changes
Solution Approach 1:
The patent establishes preliminary parameter values through manual optimization, but then enables automatic adjustment through feedback mechanisms. This allows the system to maintain accurate parameter values while eliminating the need for continuous extensive testing, reducing time loss while preserving precision.
Solution Approach 2:
The system dynamically changes mobility control parameters based on real-time terminal moving state reports. Instead of using fixed parameters determined through lengthy outdoor tests, the system automatically adapts parameters to current conditions, reducing the time required for parameter determination while maintaining accuracy.
3Productivity
If mobility control parameters are manually adjusted based on statistical analyses, then optimal handover performance can be achieved, but the system lacks automatic adaptation to changing terminal and cell conditions
Solution Approach 1:
The patent transforms static manually-determined parameters into dynamic automatically-adjusted parameters. The system continuously adapts mobility control parameters based on real-time terminal moving state reports, enabling automatic adaptation to changing conditions while maintaining high handover performance.
Solution Approach 2:
The feedback mechanism where terminals report their moving state enables the base station to automatically adjust parameters in response to changing conditions. This maintains optimal handover performance while adding automatic adaptability, resolving the contradiction between productivity and adaptability.
Data Source
AI summary
The present invention discloses a method for adjusting control parameters. The method includes: when a terminal fails to be handed over from a source cell to a target cell, or when the terminal is handed over from a source cell to a target cell successfully and a radio link connection failure occurs on a radio link established between the terminal and the target cell, reestablishing, by the terminal, a radio link with a reestablished cell; and sending, by the terminal, a report message to a base station of the reestablished cell, where the report message carries moving speed information of the terminal and/or size information of the target cell.
