Core Network Reversion Based on Geographic Alert Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in managing network failures or alarms effectively, particularly when a large number of alerts originate from a specific geographic area, leading to potential cascading failures without adequate automatic reversion to prior configurations.
Innovation Solution
An apparatus and method that define geographic areas enclosing all core network nodes, determine the number of alerting nodes within these areas, and trigger automatic reversion or user prompting for reversion of core network nodes to prior configurations when the number of alerts exceeds a threshold, considering recent reconfigurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual monitoring and reversion of core network nodes is performed, then operational control and flexibility are maintained, but response time to cascading failures increases and operational complexity increases
Solution Approach 1:
The system performs preliminary actions by automatically detecting cascading failure patterns through geographic area analysis and proactively triggering reversion of core network nodes before complete network collapse occurs. The management entity continuously monitors alert patterns and pre-identifies nodes that require reversion, eliminating manual detection delays.
Solution Approach 2:
The network management system performs self-service by automatically detecting cascading failures through geographic alert analysis, determining which core network nodes need reversion, and executing the reversion process without human intervention. The system monitors its own health status and autonomously initiates corrective actions.
2Extent of automation
If geographic area monitoring with threshold-based automatic reversion is implemented, then response speed and automation improve, but system complexity and false alarm risk increase
Solution Approach 1:
The system segments the network monitoring function by dividing the network into geographic areas and analyzing alerts within each segment independently. The management entity determines the geographic area of each core network node and counts alerts specific to each area, allowing localized automated responses without requiring complex global analysis.
Solution Approach 2:
The system uses parameter changes by establishing threshold values for alert counts in geographic areas. When the number of alerts in a geographic area exceeds the threshold, the system automatically triggers reversion of core network nodes. This parameter-based approach simplifies automation logic while maintaining effective control.
3Measurement precision
If comprehensive monitoring of all core network nodes is performed, then detection accuracy improves, but computational load and processing time increase
Solution Approach 1:
The system applies local quality by focusing monitoring resources on geographic areas where cascading failures are detected rather than uniformly monitoring all network nodes. The management entity determines the geographic area of each alert and concentrates analysis on specific regions, reducing overall computational load while maintaining high detection accuracy for critical areas.
Solution Approach 2:
The monitoring system is segmented by geographic area, with each area independently analyzed for alert patterns. This segmentation allows the system to process alerts in smaller, manageable groups rather than analyzing all network nodes simultaneously, reducing computational complexity while maintaining comprehensive coverage.
