NodeB Software Package Validation Using Baseline-Aware Criteria
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Software package updates in wireless network infrastructure can lead to performance degradation due to interoperability issues and compatibility problems, potentially causing crashes, instability, and resource inefficiencies.
Innovation Solution
A method for validating software packages by logging performance indicators before and after installation, comparing these indicators, and adjusting validation criteria based on the impact of reference features to determine whether the package improves or degrades network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software package updates are deployed to improve functionality and fix bugs, then software stability and features are improved, but network performance may degrade due to interoperability issues and compatibility problems
Solution Approach 1:
The system performs preliminary validation of software packages by testing them in a controlled environment before deploying to the production network. Performance indicators are collected and analyzed in advance to predict potential impacts, allowing the system to prepare validation criteria and detect issues before they affect actual network operations.
Solution Approach 2:
The system establishes a feedback loop where performance indicators are continuously monitored and compared against validation criteria after software package deployment. This feedback mechanism allows the system to detect performance degradation and trigger validation processes, enabling continuous improvement and rapid response to issues.
2Reliability
If validation criteria are made stringent to ensure network performance, then network reliability is improved, but the process complexity and time required for validation increase
Solution Approach 1:
The system dynamically adjusts validation criteria based on the specific software package being validated and the current network state. Different packages may have different validation thresholds and parameters, allowing the system to optimize the validation process for each package while maintaining overall network performance standards.
Solution Approach 2:
The system replaces manual validation processes with automated computational analysis of performance indicators. By using algorithms to compare pre-and post-deployment metrics against validation criteria, the system reduces human intervention and process complexity while maintaining rigorous validation standards.
3Adaptability or versatility
If reference features are added to improve network performance, then network capabilities are enhanced, but validation becomes more difficult due to changed performance baselines
Solution Approach 1:
The system performs preliminary identification and documentation of reference features before validation begins. By knowing in advance which features are reference features and their expected impacts, the system can pre-adjust validation criteria and baseline performance indicators to account for these features, ensuring accurate comparison.
Solution Approach 2:
The system applies different validation criteria to different parts of the network based on the specific reference features being evaluated. Rather than using a single uniform validation approach, the system tailors validation parameters to the local context of each reference feature, allowing for accurate performance comparison despite the added complexity.

AI summary
Techniques for criteria modification of wireless network infrastructure software package validation are provided. A NodeB includes a network entity that is a central unit, distributed unit or radio unit. A computer system receives data representing a pre-installation reference parameter determined when the network entity is operated using a first software package and receives data representing a post-installation reference parameter determined when the network entity is operated using a second software package. The computer system stores a criterion for validating the second software package, identifies a difference between the post-installation and pre-installation reference parameters, modifies the criterion based on the difference and determines whether to validate the second software package based on the modified criterion. If validated, the computer system, sends a signal to the NodeB indicating the validation, and the NodeB causes the second software package to be installed on the network entity.
