Solution Overview

Problem

Existing communication systems face increased power consumption due to high numbers of user equipment (UEs) connected to base stations, especially in areas with congestion, leading to load increases on the base station and core network.

Innovation Solution

A communication control device and method that performs communication throttling by reducing the number of UEs connected to the base station based on thresholds, distance, and congestion levels, and adjusts communication frequency for non-essential data, while maintaining quality of service, and enables direct communication between UEs to redistribute information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the number of user equipments connected to base station is increased, then the coverage area capacity is improved, but the power consumption and network load increase

Engineering Contradiction:

Improvenumber of user equipmentsVSAvoidpower consumption

Core Design Contradiction:

Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The system dynamically changes communication parameters including communication frequency, bandwidth allocation, and transmission power based on congestion levels and UE priorities, allowing the network to maintain capacity while reducing energy consumption during high-load periods

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The communication control device implements dynamic connection management where UEs are selectively connected or disconnected from the base station based on real-time congestion conditions, UE mobility, and service requirements, transforming the static connection state into a dynamic adaptive system

Inventive Principle:

Principle #15Dynamics

2Reliability

If communication frequency is increased, then the data transmission quality is improved, but the power consumption and network load increase

Engineering Contradiction:

Improvedata transmission qualityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system adjusts communication frequency and transmission parameters dynamically based on congestion levels, UE priority, and service type, reducing communication frequency for low-priority UEs during congestion while maintaining high-frequency communication for high-priority services

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Instead of uniformly reducing communication for all UEs, the system applies partial action by selectively maintaining high communication frequency only for critical services and real-time applications, while reducing or suspending communication for non-urgent data transmission

Inventive Principle:

Principle #16Partial or excessive action

3Use of energy by moving object

If the number of connected user equipments is reduced, then the power consumption is decreased, but the service coverage capacity is reduced

Engineering Contradiction:

Improvepower consumptionVSAvoidservice coverage capacity

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

The system applies different connection management strategies to different UEs based on their location, service requirements, and priority levels, allowing selective disconnection of specific UEs while maintaining connections for others, thus reducing overall power consumption without uniformly reducing service capacity

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The network divides UEs into different groups or segments based on priority, service type, and congestion level, applying differentiated connection management to each segment, allowing the system to reduce connections in low-priority segments while maintaining service capacity in high-priority segments

Inventive Principle:

Principle #1Segmentation

4Loss of energy

If communication throttling is applied, then the network load is reduced, but the communication quality for user equipments is degraded

Engineering Contradiction:

Improvenetwork loadVSAvoidcommunication quality

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The system implements selective parameter changes where communication quality parameters such as frequency, bandwidth, and priority are adjusted based on UE-specific factors including service type, mobility state, and congestion level, rather than applying uniform throttling

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The communication quality parameters are dynamically adjusted in real-time based on changing network conditions and UE requirements, allowing the system to maintain high communication quality when conditions permit while reducing load when congestion occurs

Inventive Principle:

Principle #15Dynamics
