Network Element Alarm Integration for OSS Resource Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current alarm management approaches in complex networks require significant development effort, consume considerable processing power, and often result in silent failures due to the need for extensive OSS-NE synchronization and backward compatibility, leading to increased complexity and resource requirements.
Innovation Solution
The method generates internal connection alarms for virtual nodes at master ports of paired master and slave ports, integrating alarm conditions and allowing ports to operate in internal or normal connection modes, reducing the number of alarms communicated to OSS and processing cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional alarm management approaches are used in complex networks, then alarm monitoring and management can be performed, but significant development effort and considerable processing power are required
Solution Approach 1:
The patent merges alarm management functions into the network element itself rather than relying solely on external OSS systems. The network element generates and processes alarms locally, integrating alarm monitoring, correlation, and notification functions within the element to reduce overall system complexity and processing requirements.
Solution Approach 2:
The network element performs self-monitoring and self-management of alarm conditions. It autonomously detects alarm states, correlates related alarms, generates appropriate notifications, and manages its own operational status without requiring extensive external management system intervention, thereby reducing development and processing overhead.
2Reliability
If extensive OSS-NE synchronization is implemented to prevent silent failures, then alarm accuracy can be improved, but resource requirements and complexity increase
Solution Approach 1:
The network element performs preliminary alarm correlation and processing locally before notifications are sent to the OSS. By pre-correlating related alarms and determining alarm states in advance at the network element, the system reduces the need for extensive synchronization and processing at the OSS, thereby maintaining accuracy while reducing resource consumption.
3Quantity of substance
If master and slave port pairing is implemented for virtual nodes, then alarm integration can be achieved, but configuration complexity increases
Solution Approach 1:
The master and slave port pairing is implemented dynamically based on the operational state of ports rather than requiring static pre-configuration. The system automatically identifies which ports should be paired based on current network conditions and alarm states, reducing configuration complexity while maintaining effective alarm integration across virtual node ports.

AI summary
Multiple physical NEs may be presented to a network carrier as a single logical NE comprising multiple physical NEs. Alarms between the multiple physical NEs may be treated as internal connection alarms of the single logical NE instead of endpoint alarms of the multiple physical NEs. A number of alarms in the network may be reduced as well as alarm processing of the alarms at an Operational Support System (OSS), effectuating scaling of alarms as well as relaxing resource requirements (e.g., compute power, memory, etc.) of the OSS.
