Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G new radio (NR) systems, the SCGFailureInformation message lacks configuration information for conditional primary secondary cell (PSCell) addition or change, hindering network optimization and communication efficiency.
Innovation Solution
The method and apparatus enhance the SCGFailureInformation message by including configuration information for conditional PSCell addition or change, such as candidate cell lists, conditional configuration details, and triggered event status, enabling comprehensive failure reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the SCGFailureInformation message structure is kept simple, then message transmission is efficient, but configuration information for conditional PSCell addition or change is lost
Solution Approach 1:
The failure information is segmented into multiple fields including failure type indication, serving cell measurement information, neighboring cell measurement information, and conditionally included configuration information for conditional PSCell addition or change. This segmentation allows comprehensive information reporting while maintaining structured organization.
Solution Approach 2:
The patent adds a new dimension to the failure information message by including configuration information for conditional PSCell addition or change, which was previously absent. This extends the message from basic failure reporting to comprehensive configuration and failure analysis.
2Reliability
If comprehensive failure information is reported, then network optimization is improved, but message size and processing complexity increase
Solution Approach 1:
The patent applies local quality by including detailed measurement information specifically for serving cells and neighboring cells involved in conditional PSCell addition or change. This targeted approach provides comprehensive failure analysis information without unnecessarily increasing overall message complexity.
Solution Approach 2:
The enhanced failure information message provides feedback to the network device about configuration effectiveness and failure conditions, enabling the network to optimize conditional PSCell addition or change configurations based on actual failure scenarios.
3Adaptability or versatility
If configuration information for conditional PSCell addition or change is included, then network optimization capability is improved, but information transmission overhead increases
Solution Approach 1:
The patent includes configuration information that was prepared in advance for conditional PSCell addition or change in the failure report. This preliminary inclusion of configuration data enables immediate network optimization without requiring additional signaling exchanges.
Solution Approach 2:
The failure information message serves multiple functions: it reports failure occurrence, provides measurement data for analysis, and includes configuration information for optimization. This multi-functionality reduces the need for separate signaling messages.
