Solution Overview

Problem

Existing communication network determination apparatuses face difficulties in accurately specifying a communication network when sufficient configuration information is not acquired, as they rely on information related to the configuration of the network.

Innovation Solution

A communication network determination apparatus that calculates the number of types of communication identifiers associated with apparatus identifiers in monitoring information, determining whether the first and second communication networks are the same or different based on this calculation, allowing for accurate network specification even with limited configuration information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If configuration information is acquired to determine communication network, then network determination accuracy is improved, but acquisition difficulty and time increase

Engineering Contradiction:

Improvenetwork determination accuracyVSAvoidacquisition time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts essential identification features (communication identifiers and apparatus identifiers) from the complex configuration information. By focusing only on these critical identification elements rather than acquiring complete configuration data, the system achieves accurate network determination while significantly reducing acquisition time and complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a simplified representation (copy) of the communication network using monitoring information that contains only the essential identifiers. This copy allows for network determination without requiring the full original configuration information, thus maintaining accuracy while reducing data acquisition requirements.

Inventive Principle:

Principle #26Copying

2Measurement precision

If configuration information is acquired to determine communication network, then network determination accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvenetwork determination accuracyVSAvoidinformation acquisition complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts only the essential identification features (communication identifiers and apparatus identifiers) from the complex configuration information. By focusing on these critical elements and ignoring redundant configuration details, the system achieves accurate network determination while significantly reducing the complexity of information acquisition and processing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the configuration information into essential identification components and non-essential configuration details. By processing only the segmented identification components, the system maintains determination accuracy while reducing the complexity of handling complete configuration data.

Inventive Principle:

Principle #1Segmentation

3Measurement precision

If monitoring information is processed to determine network relationship, then network specification accuracy is improved, but processing complexity increases

Engineering Contradiction:

Improvenetwork specification accuracyVSAvoidprocessing complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts the core identification elements (communication identifiers and apparatus identifiers) from the monitoring information. By processing only these essential elements rather than the complete monitoring data, the system achieves accurate network specification while significantly reducing processing complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of processing complete configuration information to determine network relationships, the patent inverts the approach by using simplified monitoring information with essential identifiers. This inversion achieves the same determination goal with much lower processing complexity.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

Provided is a communication network determination apparatus, etc. capable of correctly specifying a communication network which can be monitored by a monitoring device even when necessary and sufficient configuration information about the configuration of the communication network cannot be obtained. A communication network determination apparatus calculates a number of types of communication identifier associated with an apparatus identifier of a second information apparatus in monitoring information where a communication identifier allocated to a first information apparatus in a second communication network and an apparatus identifier of a second information apparatus that relays a communication in a first communication network, the monitoring information generated based on communication network via the first communication network; and determines that the first communication network is the same as the second communication network when the calculated number of types is one and determines that the first communication network is different from the second communication network, otherwise.
