Correspondent Node Duplication for Network Error Replay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks, diagnosing error states in multi-vendor environments is cumbersome due to the inability to analyze all communication scenarios and message sequences comprehensively, leading to inefficient problem-solving and potential network availability issues.
Innovation Solution
The implementation of digital models of network nodes using transaction contexts to replicate messaging sequences, enabling accurate error analysis and automated remediation without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual error analysis methods are used in multi-vendor networks, then human operators can investigate error states, but the process becomes cumbersome and time-consuming due to inability to analyze all communication scenarios
Solution Approach 1:
The patent creates digital models (copies) of network nodes that replicate the behavior and state of actual network nodes. These digital models enable virtual reproduction of messaging sequences and error scenarios without affecting real network operations, allowing comprehensive analysis of all possible communication scenarios including those involving multiple vendors, thereby resolving the contradiction between thorough error analysis and time consumption
Solution Approach 2:
The system performs preliminary actions by proactively creating and maintaining digital models of network nodes before errors occur. Transaction contexts are continuously updated and stored in advance, enabling rapid error reproduction and analysis when errors do occur, thus reducing error resolution time while maintaining comprehensive analysis capability
2Measurement precision
If comprehensive analysis of all communication scenarios is attempted, then error state determination becomes more accurate, but the complexity of the system increases
Solution Approach 1:
Instead of attempting to analyze all possible communication scenarios directly in the complex multi-vendor network environment, the patent creates simplified digital models that copy the essential behavior of network nodes. These models enable comprehensive scenario analysis in a controlled virtual environment, achieving high measurement precision for error state analysis without proportionally increasing the complexity of the actual network system
Solution Approach 2:
The patent segments the complex network analysis problem into manageable components by creating individual digital models for different network nodes. Each digital model can be independently configured, updated, and analyzed, allowing comprehensive error scenario analysis to be broken down into discrete, manageable units rather than attempting to analyze the entire complex system at once

AI summary
According to an example aspect of the present invention, there is provided an apparatus comprising at least one processing core and at least one memory storing instructions that, when executed by the at least one processing core, cause the apparatus at least to store a set of transaction contexts of transactions a network function has begun with a correspondent node, initiate, based at least in part on the set of transaction contexts, a digital model of the correspondent node, and based on an error the network function encounters in a messaging sequence with the correspondent node, replicate at least partly the messaging sequence in the digital model of the correspondent node.
