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

VSEngineering 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

Engineering Contradiction:
Improvenetwork maintenance operationVSAvoidservice continuity
Core Design Contradiction:
Ease of manufactureVSReliability

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improverecovery process simplicityVSAvoidservice restoration priority
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #3Local quality

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

Engineering Contradiction:
Improverecovery process complexityVSAvoidservice restoration time
Core Design Contradiction:
Device complexityVSLoss of time

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.

Inventive Principle:
Principle #1Segmentation

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.
