Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Terminal devices in satellite communication networks face delays and unnecessary power consumption when their GNSS position information expires, causing them to enter an idle state and disrupt communication services.

Innovation Solution

A network device sends first indication information to terminal devices to perform GNSS measurements before the GNSS position information becomes invalid, ensuring the last valid position information is obtained, thereby preventing the idle state and improving communication performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If terminal devices perform GNSS measurements continuously to maintain valid position information, then the accuracy and availability of location information is improved, but power consumption increases

Engineering Contradiction:

Improveavailability of valid GNSS position informationVSAvoidpower consumption of terminal device

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The network device sends indication information to the terminal device in advance, prompting it to perform GNSS measurements before the current position information expires. This preliminary action ensures that valid position information is obtained timely, avoiding the need for continuous monitoring and reducing overall power consumption while maintaining reliability

Inventive Principle:

Principle #10Preliminary action

2Use of energy by moving object

If terminal devices wait for GNSS position information to expire before re-acquiring it, then power consumption is reduced, but service delays occur

Engineering Contradiction:

Improvepower consumption of terminal deviceVSAvoiddelay in obtaining valid GNSS position information

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The network device monitors the validity status of terminal device position information and provides feedback through indication information when re-acquisition is needed. This feedback mechanism allows terminal devices to optimize power consumption by remaining in idle state until prompted, while ensuring timely service response through network-coordinated re-acquisition timing

Inventive Principle:

Principle #23Feedback

3Use of energy by moving object

If terminal devices enter idle state when GNSS position information expires, then power consumption is reduced, but communication service continuity is disrupted

Engineering Contradiction:

Improvepower consumption of terminal deviceVSAvoidcontinuity of communication service

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

The network device sends indication information to prompt terminal devices to perform GNSS measurements before position information expires, ensuring continuous availability of valid location data for communication services while allowing terminal devices to remain in energy-efficient idle states between measurements

Inventive Principle:

Principle #10Preliminary action
