Solution Overview

Problem

Existing mobile networks face challenges in reducing energy consumption, particularly in the Radio Access Network (RAN) part, as power-saving features are ineffective during high traffic loads and do not actively manage energy usage beyond low to medium traffic periods.

Innovation Solution

Implementing a power consumption controlling unit that adapts throughput and latency of data transmission based on a power consumption policy, considering factors like electricity prices, time, and on-site power generation or battery status to balance energy savings with quality of service.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If power saving features are implemented by deactivating carriers or Power Amplifier during low traffic periods, then energy consumption is reduced, but service quality and data transmission capacity deteriorate

Engineering Contradiction:
Improveenergy consumptionVSAvoiddata transmission capacity
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The system dynamically adjusts the activation state of network components (carriers, Power Amplifier) based on real-time traffic load conditions. During low traffic periods, components are deactivated to save energy; during high traffic periods, they are activated to ensure adequate data transmission capacity. This dynamic adaptation resolves the contradiction by making the system flexible rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes operational parameters (throughput, latency) of the data transmission based on power consumption policies. By adjusting these parameters, the system can operate in energy-saving modes during low traffic while maintaining acceptable service quality, thus resolving the contradiction between energy consumption and data transmission capacity.

Inventive Principle:
Principle #35Parameter changes

2Use of energy by moving object

If resources are deactivated to save power, then energy consumption decreases, but interference increases and bandwidth utilization decreases

Engineering Contradiction:
Improvepower consumptionVSAvoidinterference
Core Design Contradiction:
Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The system dynamically controls the activation of resources based on traffic conditions and power consumption policies. By activating resources only when necessary and deactivating them during low demand, the system minimizes interference while optimizing power consumption. The dynamic nature allows the system to adapt to changing conditions rather than maintaining a fixed state.

Inventive Principle:
Principle #15Dynamics

3Use of energy by moving object

If throughput is reduced and latency increased to save energy, then power consumption decreases, but service quality deteriorates

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

Solution Approach 1:

The system changes service parameters (throughput, latency) based on power consumption policies and traffic conditions. By dynamically adjusting these parameters, the system can operate in energy-saving modes while maintaining acceptable service quality levels. The parameter changes are controlled and policy-driven, ensuring that service quality remains within acceptable bounds even during energy-saving operation.

Inventive Principle:
Principle #35Parameter changes
