Solution Overview

Problem

In wireless communication systems, users often face difficulties in receiving appropriate wireless connection services due to poor reception environments, leading to missed opportunities for content distribution by service providers.

Innovation Solution

An information processing method that allows a wireless terminal device to switch between access rights associated with different communication service providers based on reception environment conditions, enabling seamless service provision even in congested areas by setting a second access right to access a base station related to a second communication service provider.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If content distribution is performed only when reception environment is good, then distribution quality is improved, but service availability deteriorates

Engineering Contradiction:

Improvedistribution qualityVSAvoidservice availability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system changes the parameter of access rights by switching between first access right (for first communication service provider) and second access right (for second communication service provider) based on reception environment conditions, enabling content distribution to proceed under varying network conditions while maintaining appropriate quality standards

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamic switching of access rights between different communication service providers based on real-time reception environment assessment. The system dynamically determines whether to use the first access right or second access right, allowing adaptation to changing network conditions while ensuring service continuity

Inventive Principle:

Principle #15Dynamics

2Reliability

If distribution stops when reception environment is poor, then communication quality is improved, but service continuity deteriorates

Engineering Contradiction:

Improvecommunication qualityVSAvoidservice continuity

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The system changes the parameter of access rights by switching between first access right and second access right based on reception environment conditions, enabling content distribution to proceed under varying network conditions while maintaining appropriate quality standards

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces an intermediary mechanism (access right switching system) that mediates between the content distribution service and the wireless terminal device. This intermediary assesses reception environment conditions and determines whether to switch access rights, thereby maintaining service continuity while protecting communication quality

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If single access right is used, then system complexity is reduced, but service adaptability deteriorates

Engineering Contradiction:

Improvesystem complexityVSAvoidservice adaptability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements multi-functionality by equipping the wireless terminal device with multiple access rights (first access right for first communication service provider, second access right for second communication service provider). This universal access capability allows the device to adapt to different network conditions and providers without increasing operational complexity for the user

Inventive Principle:

Principle #6Universality (Multi-functionality)
