Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In communication-speed-limited scenarios, especially in mobile networks, users with restricted speeds are misclassified, leading to inaccurate throughput estimates due to their inclusion in average calculations, and may be unaware of their speed limitations, resulting in overestimated information.

Innovation Solution

A system that extracts communication-speed-limited users based on communication histories by identifying users with different throughput distributions within the same environment and time frame, using a communication history storage unit and a determination unit to isolate and correct for these users in throughput estimation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If communication speed measurement is performed including all users, then measurement coverage is improved, but measurement precision deteriorates due to inclusion of communication-speed-limited users

Engineering Contradiction:

Improvenumber of users included in measurementVSAvoidaccuracy of throughput estimation

Core Design Contradiction:

Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent segments users into two distinct groups: communication-speed-limited users and non-limited users. By separating these groups based on their throughput distribution characteristics, the system can perform measurements on non-limited users alone, thereby maintaining measurement precision while still achieving broad coverage through the segmentation approach.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts communication-speed-limited users from the overall user population by identifying their distinct throughput distribution patterns. This extraction allows the measurement system to exclude these users from throughput calculations, preventing them from distorting the average throughput values and thereby maintaining measurement precision.

Inventive Principle:

Principle #2Taking out (Extraction)

2Quantity of substance

If average throughput calculation includes all users, then data utilization is improved, but reliability deteriorates due to distortion from limited users

Engineering Contradiction:

Improveamount of data used for calculationVSAvoidaccuracy of communication speed information

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent segments the user base into communication-speed-limited and non-limited users based on throughput distribution analysis. This segmentation enables the system to calculate average throughput using only non-limited users, thereby maintaining reliability of the communication speed information while still utilizing a large amount of data from the broader user base for identification purposes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs feedback mechanisms where throughput distribution patterns are continuously analyzed to identify communication-speed-limited users. This feedback loop allows the system to dynamically adjust which users are included in throughput calculations, ensuring that only users with normal throughput patterns contribute to the average, thereby maintaining reliability.

Inventive Principle:

Principle #23Feedback

3Productivity

If communication speed limitation control is implemented, then network resource management is improved, but loss of information occurs as users are misclassified

Engineering Contradiction:

Improvenetwork resource allocation efficiencyVSAvoidaccuracy of user status identification

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent implements feedback-based identification where throughput distribution patterns are continuously monitored and analyzed. This feedback mechanism enables accurate identification of communication-speed-limited users by comparing their throughput characteristics against the overall distribution, thereby preventing misclassification while maintaining network resource management efficiency.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces simple threshold-based classification with a statistical analysis approach that examines throughput distribution patterns. This substitution of the classification mechanism allows for more accurate identification of communication-speed-limited users by considering the statistical characteristics of throughput rather than relying on fixed thresholds, thereby reducing misclassification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A communication-speed-limited user extraction apparatus for extracting a user whose communication speed is limited based on communication histories includes a communication history storage unit configured to store the communication histories including throughput information on a user-by-user basis; and a communication-speed-limited user determination unit configured to extract a communication history with a same communication environment at a communication date and time within a predetermined period of time from the communication history storage unit and determine that a user with a different throughput distribution is the user whose communication speed is limited.
