Solution Overview

Problem

Existing power management methods in mobile communication systems, such as LTE, do not effectively reflect the terminal's condition when determining DRX parameters, leading to inefficient power usage, as they rely on network-configured parameters without terminal involvement and lack a mechanism to consider background network usage.

Innovation Solution

A method and apparatus for a terminal to select power preference information based on its background network usage information, which includes measuring and processing network usage data to determine appropriate DRX parameters and transmit power preference indicators to the base station, allowing for more precise power management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If network-configured parameters are used for DRX without terminal involvement, then network control is simplified, but power management efficiency deteriorates because the terminal's actual condition is not reflected

Engineering Contradiction:
Improvenetwork control complexityVSAvoidpower management efficiency
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The terminal measures its own background network usage and feeds back this information to the base station. The base station uses this feedback to determine appropriate DRX parameters, creating a closed-loop system where the terminal's actual condition informs power management decisions without requiring complex terminal-side processing

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The terminal autonomously measures its background network usage and determines its own power preference information based on this measurement. This self-service approach allows the terminal to accurately reflect its condition while keeping the network control simple

Inventive Principle:
Principle #25Self-service

2Ease of manufacture

If PPI is standardized only recently with basic transmission procedures, then implementation is simplified, but power saving effectiveness deteriorates due to lack of determination basis for PPI

Engineering Contradiction:
Improveimplementation simplicityVSAvoidpower saving effectiveness
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The terminal performs preliminary measurement of background network usage before determining PPI. This preliminary action provides the necessary basis for accurate PPI determination while maintaining the simplicity of the standardized transmission procedure

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal determines PPI by changing parameters based on measured background network usage characteristics. This allows adaptive power saving effectiveness while keeping the implementation approach simple and aligned with existing standards

Inventive Principle:
Principle #35Parameter changes

3Productivity

If DRX parameters are determined without considering background network usage, then processing is simplified, but power savings deteriorate due to inaccurate terminal condition reflection

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidpower savings
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

Background network usage measurements are fed back to influence DRX parameter determination. This feedback mechanism enables accurate power savings without significantly increasing processing complexity, as the measurement and decision logic are integrated into the existing framework

Inventive Principle:
Principle #23Feedback
