Cell Handover Resource Configuration Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cell handover failures in communication systems often result in service interruptions, affecting user experience due to the inability to effectively manage resource configuration and restore data transmission.
Innovation Solution
A method and apparatus for cell handover that involves saving resource configuration information of the source cell during a target cell handover, allowing for immediate restoration of data transmission if the handover fails, using timers and signal quality thresholds to optimize the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cell handover is performed to improve mobility and connectivity, then user mobility is enhanced, but service interruption occurs when handover fails
Solution Approach 1:
The source cell proactively sends resource configuration information to the terminal before handover is completed. This preliminary provision of resources ensures that if handover fails, the terminal can immediately restore data transmission using the pre-sent configuration, preventing service interruption while maintaining mobility benefits
Solution Approach 2:
The invention prepares backup resource configuration information in advance and maintains it available during the handover process. This cushioning mechanism acts as a safety net that prevents service failure when handover encounters problems, thereby resolving the contradiction between enabling mobility and ensuring service reliability
2Reliability
If resource configuration information is saved during handover to enable restoration, then service reliability is improved, but system complexity increases
Solution Approach 1:
The invention extracts only the essential resource configuration information (such as radio resource configuration) from the complete handover context and sends it to the terminal. This selective extraction reduces the amount of data that needs to be managed and stored, thereby improving service restoration capability while minimizing the increase in system complexity
3Stability of the object's composition
If data transmission is stopped during target cell handover to ensure clean transition, then handover completeness is improved, but service interruption time increases
Solution Approach 1:
The source cell sends resource configuration information to the terminal before completely stopping data transmission. This preliminary action allows the terminal to have restoration resources ready in advance, enabling quicker resumption of service if handover fails, thus reducing service interruption time while maintaining handover completeness through proper transition management
