Active Set Update via Batched Cell Measurement Reports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE wireless communication systems, delayed processing of cell measurement reports during radio bearer reconfiguration can lead to outdated active set updates, resulting in communication blackouts and call drops due to cells with low signal quality being retained or included in the active set.
Innovation Solution
Implementing a method to batch and process cell measurement reports collectively after radio bearer reconfiguration, ensuring that only the most updated measurements are used to update the active set, thereby reducing delays and improving signal quality assessments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cell measurement reports are processed individually during radio bearer reconfiguration, then the active set can be updated frequently, but the processing delays cause outdated measurements to be used resulting in call drops
Solution Approach 1:
The patent combines multiple cell measurement reports that were processed individually into a single batch processing operation. By merging the processing of multiple reports that occurred during radio bearer reconfiguration, the system uses the most recent measurements collectively to update the active set, ensuring timely and accurate handover decisions without the delays caused by sequential individual processing
Solution Approach 2:
The patent performs batch processing of cell measurement reports as a preliminary action before finalizing the active set update. By collecting and processing all relevant measurements in advance using the most recent data available, the system ensures that the active set is updated with current information, preventing call drops caused by outdated measurements
2Reliability
If the active set is updated with the latest cell measurement reports, then communication reliability improves, but processing complexity increases during radio reconfiguration
Solution Approach 1:
The patent merges the processing of multiple cell measurement reports into a single batch operation, which reduces the overall processing complexity compared to handling each report separately. By combining the evaluation of multiple measurements and making a single active set update decision, the system maintains communication reliability while simplifying the processing workflow during radio bearer reconfiguration
