Solution Overview

Problem

User devices experience degraded user experience and power drain when switching between networks due to congestion, errors, and gaps in data reception, as they are unable to determine optimal times for network transitions.

Innovation Solution

User devices monitor traffic patterns and network conditions to determine opportune moments for switching between networks using handover criteria, conditions, and configurations, minimizing disruptions and resource consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the user device scans for networks to switch to, then network switching capability is improved, but gaps in data reception occur that degrade user experience

Engineering Contradiction:

Improvenetwork switching capabilityVSAvoiduser experience quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The network node performs preliminary actions by proactively providing network condition information (congestion status, error rates, traffic load) to the user device before the device needs to switch networks. This allows the device to make informed switching decisions without performing disruptive scanning operations, thereby maintaining continuous data reception and preserving user experience quality while retaining network switching capability.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the user device switches between networks, then network adaptability is improved, but power and related resources are drained

Engineering Contradiction:

Improvenetwork switching capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system implements a feedback mechanism where the network node continuously monitors network conditions and provides real-time information (congestion status, error rates, traffic load) back to the user device. This feedback enables the device to make optimal network switching decisions without exhaustive scanning, reducing power consumption while maintaining the ability to adapt to different networks based on actual conditions.

Inventive Principle:

Principle #23Feedback

3Use of energy by moving object

If the user device determines network status intermittently, then power consumption is reduced, but network condition awareness may be insufficient

Engineering Contradiction:

Improvepower consumptionVSAvoidnetwork condition information

Core Design Contradiction:

Use of energy by moving objectVSLoss of information

Solution Approach 1:

The network node acts as an intermediary that continuously monitors network conditions and provides this information to the user device. Instead of the device performing power-intensive scanning to gather network information, the network node serves as a mediator that supplies accurate, real-time network status data (congestion, errors, traffic load) to the device, ensuring complete information availability while minimizing device power consumption.

Inventive Principle:

Principle #24Intermediary (Mediator)
