Solution Overview

Problem

Existing communication systems in 5G networks do not consider energy consumption requirements when dynamically changing user data transfer routes, failing to satisfy demands for energy efficiency and renewable energy usage.

Innovation Solution

A network function within the core network acquires energy-related information and determines whether to change communication routes based on energy consumption requirements, such as energy thresholds and renewable energy ratios, using network data analytics functions to optimize route settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dynamic route changing is implemented based on communication quality requirements, then communication quality is improved, but energy consumption requirements are not considered

Engineering Contradiction:
Improvecommunication qualityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The route determination method integrates multiple determination criteria including communication quality requirements and energy consumption requirements into a single comprehensive evaluation system. The network function evaluates both aspects simultaneously to determine the optimal route, making the system universal enough to handle diverse requirements without sacrificing energy efficiency for communication quality or vice versa.

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

2Reliability

If route changing is based only on communication quality, then communication reliability is improved, but energy efficiency is not optimized

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidenergy efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The method changes the parameters used for route determination by introducing energy consumption as a new evaluation parameter alongside communication quality parameters. The network function adjusts the determination criteria dynamically, considering both communication reliability parameters and energy efficiency parameters to select the optimal route that balances both requirements rather than optimizing for one at the expense of the other.

Inventive Principle:
Principle #35Parameter changes

3Loss of energy

If energy consumption is considered in route determination, then energy efficiency is improved, but communication quality may be compromised

Engineering Contradiction:
Improveenergy efficiencyVSAvoidcommunication quality
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The route determination process is made dynamic by continuously evaluating multiple routes based on real-time communication quality requirements and energy consumption requirements. The network function adjusts its determination dynamically, selecting different routes depending on the current network conditions and requirements, ensuring that both communication quality and energy efficiency are optimized simultaneously rather than following a static preference for one over the other.

Inventive Principle:
Principle #15Dynamics
