CPAC Configuration Sharing for Accurate SCG Failure Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies are limited in their ability to accurately analyze the root cause of secondary cell group (SCG) failures, which hinders effective optimization of mobility parameters and increases the probability of such failures in network scenarios.
Innovation Solution
The method involves the master node obtaining a conditional primary secondary cell addition/change (CPAC) configuration set from the terminal device's context and sending it to the secondary node, enabling precise analysis of SCG failures by considering time and trigger conditions, thereby optimizing mobility parameters to reduce failure probability.

Engineering Contradiction Analysis
1Measurement precision
If the master node sends basic SCG failure information to the secondary node, then the information transmission is simple and quick, but the root cause analysis capability is insufficient and cannot meet increasing SCG failure scenario requirements
Solution Approach 1:
The SCG failure information is segmented into multiple fields including CPAC configuration set, time information, trigger condition information, and execution result information. Each field carries specific aspects of the failure data, allowing the secondary node to analyze different dimensions of the failure cause independently while maintaining organized and manageable information structure.
Solution Approach 2:
The terminal device performs preliminary actions by recording and preparing SCG failure information including CPAC configuration, time stamps, trigger conditions, and execution results before reporting to the master node. This preliminary data collection enables comprehensive root cause analysis without requiring complex real-time data gathering procedures when the failure occurs.
2Reliability
If the master node stores and transmits detailed CPAC configuration set, then the SCG failure analysis becomes accurate and comprehensive, but the information storage and transmission overhead increases
Solution Approach 1:
The master node extracts only the essential CPAC configuration elements relevant to SCG failure analysis from the complete terminal context, rather than transmitting all configuration data. This selective extraction includes only the CPAC configuration set, time information, trigger condition information, and execution result information necessary for root cause analysis, reducing data volume while maintaining analysis reliability.
Solution Approach 2:
Different parts of the transmitted information serve different analytical purposes: CPAC configuration set provides mobility parameter details, time information provides temporal context, trigger condition information provides activation context, and execution result information provides outcome data. Each component has specialized quality tailored to its specific analytical function, optimizing the overall analysis capability without unnecessary data overhead.
