Solution Overview

Problem

Current radio base station technologies face high switching overhead when reallocating resources among multiple base stations, leading to inefficient resource utilization and increased power consumption due to frequent resource switching and inadequate consideration of traffic fluctuations.

Innovation Solution

A radio base station apparatus with a baseband processing pool, traffic history storage, traffic prediction unit, and process resource control unit that predicts traffic fluctuations and dynamically allocates resources among signal processing modules at predetermined intervals, reducing switching overhead and optimizing resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If process resources are reallocated frequently to match traffic fluctuations, then resource utilization efficiency is improved, but switching overhead increases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidswitching overhead
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by predicting future traffic fluctuations using machine learning models before actual traffic changes occur. This allows process resources to be pre-al located in advance, avoiding the need for frequent reactive reallocations and reducing switching overhead while maintaining high resource utilization efficiency.

Inventive Principle:
Principle #10Preliminary action

2Use of energy by stationary object

If the number of operated process resources is reduced during low traffic, then power consumption is decreased, but service quality may deteriorate

Engineering Contradiction:
Improvepower consumptionVSAvoidservice quality
Core Design Contradiction:
Use of energy by stationary objectVSReliability

Solution Approach 1:

The system implements feedback mechanisms by continuously monitoring actual traffic conditions and comparing them with predictions. The machine learning models are trained using historical traffic data and performance feedback, enabling the system to dynamically adjust the number of operated process resources while maintaining service quality thresholds, thus reducing power consumption without compromising reliability.

Inventive Principle:
Principle #23Feedback

3Productivity

If resource allocation is optimized dynamically, then resource sharing efficiency is improved, but system complexity increases

Engineering Contradiction:
Improveresource sharing efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system introduces machine learning models as intermediary components between traffic monitoring and resource allocation decisions. These models process complex traffic patterns and translate them into simplified resource allocation instructions, improving resource sharing efficiency while containing system complexity by delegating computational tasks to specialized algorithms rather than complex control logic.

Inventive Principle:
Principle #24Intermediary (Mediator)
