Terminal Power Preference Selection via Background Network Usage Feedback
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
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
