Solution Overview

Problem

Users may be uncomfortable with automatic communication path switching in devices like smartphones, especially when they prefer to continue using a current connection despite declining quality due to factors like price, and lack understanding of the switching rationale.

Innovation Solution

A communication device uses machine learning-based prediction models to anticipate user intent and quality decline, predicting future communication quality and user connection preferences before switching paths, allowing informed decisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the communication device automatically switches communication paths based on quality estimation, then communication reliability is improved, but user comfort deteriorates when users prefer to keep using the current path despite quality decline

Engineering Contradiction:
Improvecommunication reliabilityVSAvoiduser comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by predicting future communication quality and user connection intentions before actual switching is needed. The prediction unit forecasts quality degradation and user preferences in advance, allowing the system to prepare for switching decisions proactively rather than reactively, thereby maintaining both reliability and user comfort.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring actual communication quality and user behavior patterns, then using this feedback to refine prediction accuracy. The learning unit processes feedback data to improve future predictions of quality decline and user intentions, creating a closed-loop system that adapts to individual user preferences while maintaining communication reliability.

Inventive Principle:
Principle #23Feedback

2Speed

If the communication device performs automatic path switching without user preference consideration, then switching speed is improved, but understanding of switching rationale deteriorates

Engineering Contradiction:
Improveswitching speedVSAvoidunderstanding of switching rationale
Core Design Contradiction:
SpeedVSLoss of information

Solution Approach 1:

The prediction unit acts as an intermediary between automatic quality monitoring and switching execution. It translates complex quality metrics and user behavior patterns into predicted user intentions, providing a rationale bridge that explains why switching decisions are made. This intermediary layer maintains fast automated switching while preserving understanding of the switching rationale through interpretable predictions.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the communication device uses simple quality threshold switching, then device complexity is reduced, but accuracy of switching decisions deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidaccuracy of switching decisions
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system replaces simple mechanical threshold-based switching with a machine learning-based prediction model. Instead of using fixed quality thresholds, the learning unit employs trained models that analyze multiple parameters including communication quality metrics and user behavior patterns, substituting complex computational processing for simple threshold comparisons to achieve more accurate switching decisions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A communication device includes circuitry configured to use a first radio communication scheme for a first radio communication. In a case where a quality of the radio communication using the first radio communication scheme satisfies a condition, the circuitry may be configured to use a prediction model of an application's action related to the radio communication to predict a second radio communication scheme desired by the application. The prediction model may be a learning model generated based on at least one of an action parameter related to the radio communication of the application and an environmental parameter related to the radio communication. The second radio communication scheme desired by the application may be predicted at a time interval after the quality of the radio communication using the first radio communication scheme satisfies the condition.
