5G Cloud Event Coordination for Outage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for ensuring high reliability in 5G communications across multiple network domains, such as the wireless and cloud domains, often result in communication outages when simultaneous interruptions occur in both domains, compromising service quality, especially in critical use cases like Industry Automation and Mission Critical Services.
Innovation Solution
An event coordination function is introduced, utilizing an exposure API to synchronize actions between the 5G network and cloud domains, allowing authorized entities to send lock requests and manage actions to prevent interruptions, ensuring harmonized event handling and maintaining uninterrupted communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant communication paths are established in both 5G network domain and cloud domain, then service reliability is improved, but communication outages occur when simultaneous interruptions happen in both domains
Solution Approach 1:
An event coordination function is introduced as an intermediary system between the 5G network domain and cloud domain. This coordinator receives event information from both domains, analyzes potential conflicts, and generates coordination actions to prevent simultaneous outages. The intermediary resolves the contradiction by adding a layer of intelligent coordination that manages the complexity of redundant paths while maintaining high reliability.
Solution Approach 2:
The system performs preliminary actions by predicting potential communication outages before they occur. The event coordination function analyzes upcoming events in both domains (such as planned maintenance, handovers, or application instance transitions) and proactively generates coordination actions to prevent simultaneous interruptions. This preliminary intervention ensures reliability without requiring complex real-time reaction mechanisms.
2Stability of the object's composition
If multiple application instances are deployed in cloud environment with redundant UEs in 5G network, then service continuity is improved, but coordination complexity between domains increases
Solution Approach 1:
The event coordination function merges the event management of multiple application instances and redundant UEs into a unified coordination system. Instead of managing each instance and UE separately, the coordinator consolidates event information from all sources, identifies correlations, and generates coordinated actions that maintain service continuity across the entire system. This merging reduces the perceived coordination complexity while preserving service stability.
Solution Approach 2:
The event coordination function serves multiple functions simultaneously: it monitors events from both 5G network and cloud domain, analyzes potential conflicts, generates coordination actions, and manages multiple application instances and UEs through a single unified interface. This multi-functionality reduces coordination complexity by providing a universal management mechanism that handles diverse scenarios through consistent processes.
3Reliability
If lock requests are implemented to prevent simultaneous events, then communication outage prevention is improved, but response time for critical events may increase
Solution Approach 1:
The system implements partial locking by selectively applying coordination actions only to specific communication paths or events that are at risk of simultaneous outages. Instead of locking all events globally, the event coordination function identifies critical paths and applies targeted lock requests only where necessary. This partial action maintains outage prevention effectiveness while minimizing the impact on event response time for non-critical events.

AI summary
A method for coordinating application-related events in multiple network domains comprises, in a first network domain, receiving (710) a request, from a second network domain, to prevent events with respect to a first communications path in the first network domain, for a communications module. The method further comprises preventing or delaying (720) one or more actions in the first network domain that would interrupt connectivity in the first communication path, in response to the request.
