Solution Overview

Problem

Existing DRX configurations in terminals are inaccurately set by network devices, leading to inefficiencies in energy consumption and potential data delays or losses due to misjudged active states.

Innovation Solution

Implementing an AI model on the terminal to predict data arrival and control its state based on predicted output values, allowing self-regulation of active and inactive states for optimized energy savings and timely data reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the network device configures DRX by estimating data arrival cycle and delay, then the terminal can reduce energy consumption by monitoring PDCCH only in active state, but the estimation accuracy is insufficient leading to inappropriate DRX configuration

Engineering Contradiction:
Improveterminal energy consumptionVSAvoiddata arrival time estimation accuracy
Core Design Contradiction:
Loss of energyVSMeasurement precision

Solution Approach 1:

The terminal device autonomously determines its active and inactive states by making predictions about data arrival using an AI model, rather than relying on network device configuration based on imprecise estimates. This self-service approach allows the terminal to independently optimize its monitoring behavior according to actual data patterns.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the traditional mechanical estimation approach (network device guessing data arrival based on historical patterns) with an AI-based predictive system. The AI model analyzes multiple factors including service types, data volumes, and terminal behaviors to make accurate predictions about data arrival, substituting crude estimation with intelligent prediction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of energy

If the terminal uses inaccurate DRX configuration, then energy saving is achieved through reduced PDCCH monitoring, but data transmission delays or losses occur

Engineering Contradiction:
Improveterminal energy consumptionVSAvoiddata transmission reliability
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The AI model continuously learns from actual data arrival patterns and terminal state outcomes, adjusting its predictions to improve accuracy over time. This feedback mechanism ensures that the terminal's active state determination becomes increasingly reliable, preventing both energy waste and data transmission failures.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The terminal uses the AI model to predict data arrival in advance and proactively transitions to active state before data actually arrives. This preliminary action ensures the terminal is ready to receive data immediately when it arrives, preventing transmission delays while avoiding prolonged active states that would waste energy.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the terminal constantly monitors PDCCH to ensure timely data reception, then data transmission reliability is improved, but energy consumption increases

Engineering Contradiction:
Improvedata reception reliabilityVSAvoidterminal energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The terminal dynamically adjusts its monitoring state based on AI-predicted data arrival patterns. Instead of constant monitoring or fixed DRX cycles, the terminal flexibly transitions between active and inactive states according to real-time predictions, optimizing the balance between energy consumption and reception reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The AI model predicts multiple parameters including data arrival time, service type, and data volume, which the terminal uses to adjust its monitoring parameters. By changing monitoring behavior based on these predicted parameters, the terminal achieves reliable data reception only when necessary, significantly reducing overall energy consumption.

Inventive Principle:
Principle #35Parameter changes
