Network Element Recovery Sequencing by KPI-Based Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication network management systems fail to prioritize the recovery of network elements post-outage based on their relative impact on user equipment, leading to disrupted services, especially in critical areas like hospitals.
Innovation Solution
A network management system determines a sequence for recovering network elements based on priority values derived from key performance indicators (KPIs), ensuring critical services are resumed first by prioritizing network elements providing services to important locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If network elements are rebooted during network maintenance or due to unforeseen reasons, then network maintenance operations can be performed, but service disruption occurs for user equipment
Solution Approach 1:
The system performs preliminary actions by determining priority values for network elements before the actual recovery process. The network management system assesses the impact of each network element on user equipment and pre-establishes a recovery sequence based on priority, ensuring that critical services are restored first before less critical ones.
2Ease of operation
If existing protocols are used for network element recovery, then recovery process is simple, but service requests are processed without considering the relative impact on user equipment
Solution Approach 1:
The system applies local quality by assigning different priority levels to different network elements based on their specific impact on user equipment. Instead of treating all network elements uniformly, the system evaluates and prioritizes each element individually according to its criticality, ensuring that network elements serving essential services receive higher priority for recovery.
3Device complexity
If all network elements are recovered simultaneously, then recovery process is straightforward, but critical services in areas like hospitals cannot be resumed at the earliest
Solution Approach 1:
The system segments the network elements into different priority groups based on their impact on user equipment. The network management system divides the recovery process into sequential phases, where high-priority network elements (serving critical services) are recovered first, followed by medium-priority elements, and finally low-priority elements. This segmentation enables targeted recovery of critical services without delaying less critical ones.

AI summary
A method of recovering a plurality of network elements from a network outage, including receiving, at a network management system (NMS), a plurality of recovery requests from the plurality of network elements; determining, by the NMS, a sequence for processing the plurality of recovery requests based on a plurality of priority values associated with the plurality of network elements, wherein a priority value of the plurality of priority values is based on at least one key performance indicator (KPI) associated with a corresponding network element of the plurality of network elements; and recovering the plurality of network elements based on the determined sequence.
