Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale mobile networks built on virtualization infrastructure, it is challenging to expedite and automate the deployment of workarounds (WAs) across numerous devices and functions due to the complexity of identifying and applying fixes to similar problems across the network.
Innovation Solution
A network management apparatus that includes a configuration information storage unit, property information acquisition unit, application target extraction unit, and execution request unit, which extracts and prioritizes devices and functions for WA application based on common configuration information, enabling selective and efficient deployment of WAs across the virtualized environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual identification and application of workarounds is performed in large-scale virtualized networks, then accuracy of targeting affected devices can be maintained, but time consumption and operational complexity increase significantly
Solution Approach 1:
The system pre-establishes correspondence relationships between device configuration information and workaround application targets before actual incidents occur. When a problem is detected, the pre-configured mappings enable rapid identification of affected devices without manual analysis, thus maintaining accuracy while reducing deployment time
Solution Approach 2:
The patent introduces a management server as an intermediary that maintains a database mapping device configuration properties to workaround targets. This intermediary automatically matches incident characteristics with corresponding workarounds by comparing configuration information, eliminating manual identification while preserving accuracy through systematic matching
2Reliability
If workarounds are applied to all devices in the network, then reliability is improved by preventing similar issues, but unnecessary operations increase on devices not affected by the problem
Solution Approach 1:
The system applies workarounds selectively based on local configuration characteristics of each device. By comparing specific configuration properties (such as software versions, hardware models, or deployment settings) against the incident profile, only devices with matching local qualities are targeted, avoiding unnecessary operations on unaffected devices while ensuring comprehensive coverage of affected ones
Solution Approach 2:
The patent uses configuration parameters as the basis for determining workaround applicability. By changing the approach from blanket application to parameter-based filtering, the system identifies subsets of devices whose configuration parameters match the incident characteristics, thus applying workarounds only where needed to maintain reliability without wasting operations
3Manufacturing precision
If comprehensive configuration information is collected from all devices, then exhaustive identification of affected devices is enabled, but system complexity and data management burden increase
Solution Approach 1:
The system extracts only the specific configuration information items that are relevant to identifying affected devices by the particular incident. Rather than collecting and managing all possible device parameters, the management server extracts and stores only those configuration properties that serve as effective matching criteria for workaround application, reducing data complexity while maintaining identification exhaustiveness
Solution Approach 2:
The patent segments configuration information into hierarchical levels: device-specific details, common configuration patterns, and incident-relevant attributes. By organizing configuration data in segments and only managing the segments relevant to incident response in the correspondence database, the system achieves exhaustive identification capability without bearing the full burden of complete device configuration complexity

AI summary
A network management apparatus includes at least one memory configured to store program code; and electric circuitry including at least one processor, the at least one processor being configured to read and operate according to the program code, the electronic circuitry configured to: store configuration information on devices or functions that constitute a virtualized environment of a network; acquire, as property information of the workaround, information associated with one or more devices or one or more functions to which a workaround for a specific hardware or software problem is to be applied; extract the one or more devices or the one or more functions serving as an application target of the workaround by referring to the configuration information based on the property information; and request to execute the workaround with respect to the application target.
