Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the ANR algorithm is used to automatically adjust neighbor relationships, then the network can automatically optimize neighbor cell lists and improve network performance, but it becomes impossible to determine whether UE performance degradation or user experience issues are caused by the ANR algorithm
Solution Approach 1:
The patent implements a feedback mechanism by collecting statistical data on ANR operations (number of PCI conflicts, unknown PCIs, new unknown neighbor cells, successful handovers, conflict cells, overshoot coverage cells, GCI reading delays) and using this feedback to evaluate whether ANR operations are causing performance degradation. This allows the system to monitor and assess the impact of automatic adjustments in real-time.
Solution Approach 2:
The patent introduces an intermediary evaluation mechanism that acts as a mediator between the automatic ANR algorithm and performance monitoring. By collecting and analyzing statistical data through this intermediary layer, the system can determine the causal relationship between ANR operations and performance issues without disrupting the automation process.
2Measurement precision
If comprehensive statistical data is collected to evaluate ANR impact, then the ability to identify ANR-related performance issues is improved, but the complexity of the evaluation system increases
Solution Approach 1:
The patent segments the evaluation system into distinct functional modules: data collection module (gathering various statistical metrics), data processing module (analyzing collected data), and evaluation module (determining ANR impact). This segmentation allows comprehensive monitoring while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The patent creates a universal evaluation framework that can assess multiple aspects of ANR impact simultaneously using a single integrated system. The same evaluation mechanism handles diverse metrics including PCI conflicts, handover success rates, GCI reading delays, and neighbor cell additions, eliminating the need for separate monitoring systems for each metric.
