Innovation Solution
A network performance optimization system comprising an intelligent anomaly detector, a network performance health monitor, and a network reconfiguration system that learns traffic patterns to proactively identify anomalies, maximizes user Quality of Experience (QoE) by tying user perception to network KPIs, and adjusts network settings such as antenna tilt angles, routing paths, and bandwidth to prevent issues before they occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network capacity is expanded to handle exponential user growth, then network throughput increases, but network complexity and infrastructure costs increase
Solution Approach 1:
The system performs preliminary actions by continuously learning and establishing baseline traffic patterns for each network cell. This proactive approach allows the anomaly detection system to identify deviations before they become critical issues, enabling preventive maintenance and optimization rather than reactive problem-solving after network failures occur.
Solution Approach 2:
The network monitoring system operates autonomously by automatically collecting performance data, learning normal traffic patterns through machine learning algorithms, detecting anomalies, and generating alerts without requiring constant human intervention. This self-service capability reduces operational complexity while maintaining high network throughput.
2Reliability
If network monitoring and optimization systems are enhanced to maintain quality of service, then user experience improves, but system complexity increases
Solution Approach 1:
The system implements continuous feedback loops by monitoring network performance metrics, comparing them against learned baseline patterns, and automatically generating alerts when anomalies are detected. This feedback mechanism enables dynamic adjustment of network parameters to maintain quality of service while using standardized monitoring tools that do not excessively increase system complexity.
Solution Approach 2:
The system maintains quality of service by dynamically analyzing changes in network performance parameters such as traffic volume, signal strength, and error rates. By focusing on parameter changes rather than attempting to control all system aspects, the monitoring approach achieves high reliability without proportionally increasing system complexity.
3Reliability
If proactive anomaly detection is implemented to prevent network issues, then network reliability improves, but data processing requirements increase
Solution Approach 1:
The system applies partial action by focusing anomaly detection efforts on specific network cells and performance parameters that are most critical for maintaining reliability. Rather than exhaustively analyzing all possible data points across the entire network, the system selectively monitors key indicators, reducing data processing energy consumption while still achieving improved network reliability through targeted anomaly detection.
Data Source
AI summary
A system may collect, from a wireless network, first data pertaining to nodes in the wireless network. Each datum of the first data belongs to one of two or more categories/For each of the nodes, for each of the categories, and for each datum belonging to the category, the system may determine if the datum is outside of a first range of values, and if the datum is inside the first range, the system may calculate a first base network performance health (NPH) score that is a function of the nodes, the categories, the data, and time. The system may also apply first deep learning to a first neural network among a plurality of neural networks to update first coefficients for correlating the first base NPH score to a mean opinion score, for each of the categories.
