Handover Type Indication for Mobility Parameter Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accurately identifying the type of handover, such as normal, conditional, or conditional combined with DAPS handover, which hinders optimal mobility parameter optimization and re-establishment after radio link failures or Secondary Cell Group failures during handovers.
Innovation Solution
The wireless device is configured to transmit an indication of the handover type to the base station upon detection of a radio link failure or Secondary Cell Group failure, allowing the base station to adjust parameters accordingly and differentiate between various handover types, including normal, conditional, and conditional combined with DAPS handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wireless device transmits detailed handover type indication information to the base station, then the base station can optimize mobility parameters more accurately, but the signaling overhead and system complexity increase
Solution Approach 1:
The patent extracts only the essential handover type indication information (normal handover, conditional handover, or conditional handover combined with DAPS handover) from the complete handover process data, transmitting only this specific classification to the base station. This selective extraction achieves accurate handover type identification while minimizing signaling overhead and system complexity.
2Reliability
If the base station implements comprehensive analysis of handover failure causes, then the reliability of mobility optimization improves, but the processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary classification of handover types (normal, conditional, or conditional combined with DAPS) immediately upon detecting handover failure, before conducting detailed cause analysis. This preliminary action organizes the failure data by handover type, enabling the base station to apply type-specific optimization strategies efficiently, thereby improving reliability while reducing overall processing time.
Solution Approach 2:
The patent segments the handover failure analysis process into distinct phases: handover type identification, failure cause analysis, and optimization parameter adjustment. By dividing the comprehensive analysis into manageable segments, the system can process each aspect systematically, improving both reliability and efficiency of the mobility optimization process.
