Solution Overview

Problem

Existing technologies fail to efficiently integrate discontinuous reception (DRX) cycles with machine learning (ML) life cycles in user equipment (UE), leading to disrupted data collection and delayed ML model operations due to DRX off periods, affecting predictive accuracy and power consumption.

Innovation Solution

Implement prioritization policies and RRC configuration parameters to synchronize DRX and ML life cycles, allowing the UE to autonomously or network-centrically manage DRX and ML functionalities, including conditions for prioritizing power saving or ML operations based on reliability thresholds and time collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If DRX off periods are implemented for power saving, then energy consumption is reduced, but data collection for ML models is disrupted and ML operations are delayed

Engineering Contradiction:
Improvepower consumptionVSAvoidML model operation reliability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent implements dynamic adjustment of DRX cycle configurations based on ML life cycle stage requirements. During critical ML phases such as data collection and model training, the system dynamically modifies DRX parameters to ensure continuous operation, while allowing more aggressive DRX settings during stable operational phases. This dynamic adaptation resolves the contradiction by making the DRX behavior flexible rather than static, allowing power saving when safe and reliability when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes physical and operational parameters of the DRX cycle based on ML model requirements. Specifically, it adjusts DRX cycle lengths, on-duration timers, and offset values according to the current ML life cycle stage. During data collection phases, parameters are modified to ensure continuous monitoring, while during inference phases, more aggressive power-saving parameters can be applied. This parameter adaptation directly addresses the contradiction between power saving and ML reliability.

Inventive Principle:
Principle #35Parameter changes

2Use of energy by moving object

If DRX cycles are used for power saving, then energy efficiency is improved, but predictive accuracy of ML models deteriorates due to delayed data collection

Engineering Contradiction:
Improveenergy efficiencyVSAvoidpredictive accuracy
Core Design Contradiction:
Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by proactively adjusting DRX configurations before critical ML operations begin. When the ML model enters data collection or training phases, the system pre-configures the DRX cycle to maintain continuous or near-continuous operation, ensuring that data collection is not disrupted. This preliminary adaptation prevents the degradation of predictive accuracy while still allowing energy-efficient operation during non-critical phases.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the ML model's performance metrics and data collection status are continuously monitored. Based on this feedback, the DRX cycle configuration is dynamically adjusted. If predictive accuracy begins to deteriorate due to DRX-induced data collection delays, the system receives feedback and modifies DRX parameters to restore accurate measurements. This closed-loop control resolves the contradiction by using feedback to maintain predictive accuracy while maximizing energy efficiency.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If autonomous UE management of DRX and ML cycles is implemented, then operational flexibility is improved, but device complexity increases

Engineering Contradiction:
Improveoperational flexibilityVSAvoidUE management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the ML life cycle into distinct phases (data collection, model training, validation, inference) and applies different DRX cycle configurations to each phase. This segmentation allows the UE to autonomously manage DRX settings based on the current phase, improving operational flexibility. The complexity is managed by providing clear phase-based rules rather than requiring complex real-time optimization algorithms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The UE is empowered to autonomously manage its own DRX and ML cycle coordination without requiring constant network intervention. The device uses self-service mechanisms where it automatically detects ML life cycle stages and adjusts DRX parameters accordingly, reducing the need for complex network-UE coordination protocols. This self-management capability improves operational flexibility while keeping the implementation complexity manageable through rule-based autonomous decision-making.

Inventive Principle:
Principle #25Self-service
