Remote Network Node Reachability With Programmable Auto Rollback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile network configurations, particularly in 4G and 5G networks, face challenges in dynamically adapting to changing operational requirements without causing disruptions due to erroneous configurations, leading to loss of connectivity and the inability to automatically revert to a previous working state when issues arise.
Innovation Solution
A system and method that includes a device-specific operational check ecosystem in the Network Operating System (NOS) to analyze configurations before implementation, allowing for automatic rollback to a previous state if connectivity is negatively impacted, with customizable operational checks and a fail-safe mode to ensure network integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If runtime configuration updates are implemented to adapt to changing network requirements, then network adaptability is improved, but the risk of service disruption increases when erroneous configurations are applied
Solution Approach 1:
The system performs preliminary operational checks on configuration changes before they are applied to the network. The check function validates the proposed configuration against predefined operational criteria to ensure it will not disrupt existing services, allowing the network to adapt safely to new requirements
Solution Approach 2:
The system implements a feedback mechanism where the result of operational checks is fed back to determine whether a configuration change should be applied. If the check indicates the configuration would cause service disruption, the feedback loop prevents the change from being applied, thus maintaining service continuity while still allowing safe adaptations
2Object-affected harmful factors
If configuration changes are applied to address security attacks, then network security is improved, but the complexity of configuration management increases
Solution Approach 1:
The system provides self-service capability by automatically checking and validating configuration changes against operational criteria. The check function autonomously determines whether a security-related configuration change is safe to apply, eliminating the need for manual verification and reducing configuration management complexity
3Ease of operation
If manual configuration changes are made at remote cell sites, then operational flexibility is improved, but the time required to respond to issues increases
Solution Approach 1:
The system implements automated feedback through operational checks that immediately validate configuration changes. When a configuration error is detected, the system automatically rolls back the change, providing rapid response to issues without requiring manual intervention at remote cell sites
Solution Approach 2:
The system replaces manual mechanical configuration changes with an automated software-based check and rollback mechanism. The check function and rollback capability operate automatically through software, eliminating the need for physical travel to remote sites and significantly reducing response time
Data Source
AI summary
A system and a method for providing a set of operational checks to be implemented prior to configuration changes being made in a mobile network that includes a user computer connected to a management configuration system and connected to a data center having a storage and to a computer located at a remote cell site. The management configuration system provides for saving of an existing system configuration, and the automatic execution of a script that comprises a set of user-specified and programmed operational checks to ensure a new system configuration is valid prior to implementation of the new configuration on the system, where if the new configuration fails the operational checks, the system automatically rolls back to the previous configuration.
