Solution Overview

Problem

Satellite communication systems face challenges in areas with poor signal coverage, such as indoors and sheltered areas, where terminals cannot receive normal paging information, leading to inadequate communication.

Innovation Solution

A paging method and device that sends first and second paging channels based on signal quality thresholds, with the second paging channel prompting terminal location adjustments in poor coverage areas, using DCI or preset sequences to guide terminals to better signal locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional paging channels are used in satellite communication systems, then paging can be performed in areas with good signal coverage, but terminals in areas with poor signal coverage (indoor, sheltered areas) cannot receive paging information

Engineering Contradiction:

Improvepaging reception reliabilityVSAvoidcoverage area adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The paging channel is segmented into two types: first paging channel for terminals with good signal quality and second paging channel for terminals with poor signal quality. This segmentation allows the system to provide differentiated paging services based on signal conditions, improving both reliability and coverage adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different paging channels are assigned to different signal quality conditions. Terminals with poor signal quality (indoor/sheltered areas) receive the second paging channel with location adjustment prompts, while terminals with good signal quality receive the first paging channel. This local quality differentiation ensures reliable paging delivery across diverse coverage areas.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If the system provides paging services to all terminals regardless of signal quality, then coverage is extended, but the complexity of the paging system increases

Engineering Contradiction:

Improvecoverage area adaptabilityVSAvoidpaging system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system changes the paging channel parameter based on signal quality measurements. Terminals measure signal quality and select appropriate paging channels (first or second) based on whether the quality exceeds a threshold. This parameter-based adaptation extends coverage without requiring complex system architecture changes.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The paging system dynamically adapts to terminal signal conditions by providing different paging channels based on real-time signal quality measurements. This dynamic approach allows the system to extend coverage to poor signal areas while maintaining simplicity through conditional logic rather than complex structural changes.

Inventive Principle:

Principle #15Dynamics

3Reliability

If terminals in poor coverage areas receive paging information, then communication reliability improves, but the accuracy of paging delivery decreases due to signal quality issues

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidsignal quality threshold accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The second paging channel acts as an intermediary for terminals in poor coverage areas. Instead of forcing these terminals to use the first paging channel where signal quality degrades accuracy, the system provides a dedicated second paging channel with location adjustment prompts, ensuring reliable and accurate paging delivery adapted to their signal conditions.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The present disclosure provides a paging method and apparatus, and a storage medium. The paging method comprises: sending a first paging channel and/or a second paging channel to terminals belonging to the same terminal group, first paging being used for corresponding paging when signal quality is greater than a target signal threshold, and second paging being used for corresponding paging when the signal quality is less than or equal to the target signal threshold. The present disclosure can provide, in an area having poor signal coverage for network devices, a prompt that the position where a terminal is located needs to be adjusted, so that a user adjusts the position where the terminal is located, so as to facilitate subsequent reception of the first paging channel, achieving the purpose of paging in the area having poor signal coverage for network devices.
