Solution Overview

Problem

The increasing demand for wireless communication resources due to the rise in smartphone usage and large data downloads has led to inefficient frequency utilization, particularly in mobile environments, where users face challenges in identifying and switching to less congested base stations to offload traffic effectively.

Innovation Solution

A communication system and method that enables wireless communication devices to detect and display available second base stations with lower communication costs, allowing users to seamlessly switch and offload traffic, utilizing a combination of position information acquisition, base station selection, and display control units to provide users with real-time base station information and guide them to less congested networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wireless communication devices continue to use the same base station, then connection stability is maintained, but network congestion increases and communication efficiency deteriorates

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidconnection stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary actions by predicting the user's migration path in advance and identifying suitable base stations along that path before the user actually needs to switch. The position information acquisition unit continuously tracks user location, and the base station selection unit pre-identifies candidate base stations, so when handover becomes necessary, the transition is smooth and immediate, maintaining connection stability while improving communication efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the display control unit provides real-time information to users about available base stations and their characteristics. This feedback enables users to make informed decisions about base station switching, balancing connection stability with communication efficiency by allowing voluntary switching when users perceive benefits.

Inventive Principle:
Principle #23Feedback

2Productivity

If users manually search for better base stations, then resource utilization can improve, but user effort and time consumption increase

Engineering Contradiction:
Improveresource utilizationVSAvoiduser effort
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system enables self-service by automatically performing base station selection and providing relevant information to users without requiring manual searching or complex operations. The base station selection unit autonomously identifies suitable base stations based on predicted migration paths, and the display control unit automatically presents this information in an user-friendly format, thereby improving resource utilization while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If multiple base stations are deployed to increase capacity, then network coverage improves, but system complexity and infrastructure costs increase

Engineering Contradiction:
Improvenetwork coverageVSAvoidsystem complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent makes existing base stations multi-functional by enabling them to serve multiple purposes: their primary communication function plus their role as candidate base stations for predicted migration paths. This universal approach allows the system to improve network coverage and capacity utilization without requiring additional specialized infrastructure, thereby avoiding increased system complexity while still deploying multiple base stations strategically.

Inventive Principle:
Principle #6Universality (Multi-functionality)
