Solution Overview

Problem

Existing power-saving modes for terminal devices in communication systems are not optimally configured, failing to meet the specific power-saving demands of individual devices, leading to inefficient power consumption.

Innovation Solution

A method where a network device determines power-saving configuration information for a terminal device based on its characteristic information, such as subscription and service details, to tailor power-saving settings like DRX cycles, sleep durations, and wake-up times, ensuring better alignment with the device's power-saving requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If power-saving mode configuration is determined through negotiation between network device and terminal device, then configuration flexibility is improved, but the configuration may not satisfy specific requirements of the terminal device

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoidpower-saving requirement satisfaction

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The terminal device autonomously determines its own power-saving mode configuration based on its characteristic information, eliminating the need for negotiation with the network device. The terminal device selects appropriate power-saving parameters (such as DRX cycle lengths, PSM activation conditions) that best match its specific requirements, ensuring both adaptability and reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The terminal device changes its operating parameters by selecting from multiple power-saving mode configurations based on its characteristic information. By adjusting parameters such as DRX cycle duration, sleep window timing, and PSM activation thresholds, the terminal device optimizes power consumption while maintaining service quality.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If generic power-saving configurations are used for all terminal devices, then system complexity is reduced, but power-saving performance does not meet individual device requirements

Engineering Contradiction:

Improveconfiguration system complexityVSAvoidpower-saving performance

Core Design Contradiction:

Device complexityVSUse of energy by moving object

Solution Approach 1:

The power-saving configuration system is segmented into multiple predefined configuration options, each tailored to different terminal device characteristics. Instead of a single generic configuration, the system divides power-saving modes into categories (e.g., aggressive power-saving, balanced mode, performance-oriented mode) that can be selectively applied based on terminal needs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The power-saving configuration becomes dynamic by allowing terminal devices to select and switch between different configuration modes based on their characteristic information and current operational state. The configuration adapts to changing conditions without requiring complex real-time negotiation or customization.

Inventive Principle:

Principle #15Dynamics
