5G Handover RLF Reporting for Continuous Failure Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In condition-based handover processes of wireless communication systems, continuous radio link failures (RLFs) can lead to inaccurate reporting of initial RLF situations, as subsequent RLF occurrences may delete the stored report, preventing mobile communication service providers from accurately perceiving the first RLF situation.
Innovation Solution
A method and device for configuring multiple RLF reports by identifying condition-based handover support, performing handovers to first and second cells upon failure, and transmitting comprehensive RLF reports including information about failures in both handovers to the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single RLF report is stored and updated with each subsequent RLF occurrence, then the reporting mechanism remains simple, but the accuracy of the first RLF situation is lost
Solution Approach 1:
The patent divides the RLF reporting mechanism into multiple independent report structures (first RLF report and second RLF report) instead of using a single updated report. Each report preserves the specific situation of its corresponding RLF event, allowing the network to analyze different failure scenarios separately without overwriting previous information.
Solution Approach 2:
The patent stores the first RLF report before the second RLF occurs, preserving the initial failure information. By preparing and storing multiple report structures in advance rather than updating a single report sequentially, the system ensures that the first RLF situation is captured and retained even when subsequent failures occur.
2Measurement precision
If multiple RLF reports are stored for continuous RLF scenarios, then the accuracy of RLF situation perception is improved, but the complexity of the reporting mechanism increases
Solution Approach 1:
The patent segments the RLF reporting into distinct report structures for different failure events. Each report contains specific information about its corresponding RLF situation, enabling precise tracking and analysis of multiple failure scenarios without mixing or overwriting data.
Solution Approach 2:
The patent implements a feedback mechanism where the network receives multiple RLF reports and can analyze the sequence and patterns of failures. This feedback loop allows the network to perceive the actual RLF situations accurately and make informed decisions about network optimization and handover parameter adjustments.
