Solution Overview
Problem
Existing wireless telecommunication networks face challenges in effectively monitoring and managing the vast volume of operational messages from multiple components, leading to issues such as duplicate alarms, lack of clear restoration indicators, and inefficient issue resolution.
Innovation Solution
A system and method for monitoring and evaluating the operation of wireless telecommunication networks that filters, correlates, and prioritizes alarms based on importance, using connectivity and service topology to reduce duplicates and automate alarm generation, while generating metrics for improved issue management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a monitoring system tracks all operational messages from multiple network components, then complete network status visibility is achieved, but the volume of alarms and notifications becomes unmanageably large
Solution Approach 1:
The patent extracts and filters only the most relevant alarm information from the voluminous operational messages. The system identifies and prioritizes critical alarms while filtering out redundant or less important notifications, thereby maintaining complete network status visibility without being overwhelmed by the full volume of messages.
Solution Approach 2:
The patent applies different quality levels to different alarms based on their importance and impact. Critical alarms receive immediate attention with high visibility, while less important alarms are filtered or deferred. This local differentiation of alarm quality allows the system to maintain comprehensive monitoring while managing alarm volume effectively.
2Reliability
If multiple alarms are generated for similar issues from different components, then comprehensive coverage is achieved, but duplicate alarms reduce efficiency
Solution Approach 1:
The patent merges multiple alarms that indicate the same underlying issue into a single consolidated alarm notification. When similar errors or failures are detected across different network components, the system correlates these alarms and presents them as one unified alert, maintaining comprehensive issue coverage while eliminating redundant notifications that would reduce resolution efficiency.
Solution Approach 2:
The patent introduces an intermediary alarm correlation and management layer between the network components and the expert teams. This intermediary system analyzes incoming alarms, identifies patterns and duplicates, and consolidates them before presentation to operators, thereby maintaining reliable alarm coverage while improving resolution efficiency.
3Measurement precision
If expert teams manually analyze all alarms, then thorough investigation is achieved, but time consumption increases significantly
Solution Approach 1:
The patent performs preliminary analysis and filtering of alarms automatically before they reach expert teams. The system pre-processes alarm data, identifies patterns, correlates related alarms, and prioritizes notifications, so that when experts do review alarms, they are presented with already-analyzed, consolidated, and prioritized information requiring minimal additional investigation time.
Solution Approach 2:
The patent enables the alarm management system to serve itself through automated correlation, filtering, and prioritization capabilities. The system automatically processes and prepares alarm information without requiring manual intervention for every alarm, allowing expert teams to focus their thorough investigation skills on the most critical and complex issues rather than routine notifications.
4Speed
If the monitoring system processes all messages in real-time, then immediate detection is achieved, but system complexity increases
Solution Approach 1:
The patent segments the alarm processing function into multiple hierarchical levels: initial filtering, correlation analysis, prioritization, and expert review. This segmentation allows real-time processing of critical functions while deferring or simplifying less time-sensitive operations, thereby maintaining immediate detection capability without requiring the entire system to operate at full real-time complexity.
Data Source
AI summary
The system receives multiple messages from multiple components of a wireless telecommunication network. The multiple messages indicate a state associated with the multiple components and include a first message generated by a first component among the multiple components and a second message generated by a second component among the multiple components. The system filters the multiple messages received based on content associated with a first message among the multiple messages to obtain multiple filtered messages. The content indicates importance associated with the first message. The system determines whether the first message and the second message are similar. Upon determining that the first message and the second message are similar, the system automatically creates an alarm representing both the first message and the second message, thereby reducing a number of alarms generated from the multiple filtered messages.
