Solution Overview

Problem

Existing communication systems face challenges in ensuring prompt receipt of emergency communications due to overlapping paging timings from multiple networks, which can lead to missed pagings for critical alerts.

Innovation Solution

Assigning priority to paging timings and types from multiple networks, allowing communication terminals to selectively receive pagings based on these priorities, thereby ensuring preferential reception of emergency communications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple networks transmit paging signals simultaneously without priority differentiation, then network coverage and connectivity options are improved, but emergency communications may be missed due to timing overlaps

Engineering Contradiction:

Improveemergency communication reception reliabilityVSAvoidpaging timing management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by differentiating paging signal handling based on their source network. Emergency network paging signals are treated with higher priority and different processing characteristics compared to non-emergency networks. The terminal maintains separate reception criteria for emergency versus non-emergency paging, allowing selective reception based on network type and signal priority level.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If the terminal receives all paging signals from multiple networks, then connectivity awareness is improved, but processing burden and power consumption increase

Engineering Contradiction:

Improvenetwork connectivity awarenessVSAvoidterminal power consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts and separates emergency paging signals from non-emergency paging signals based on network identification. The terminal extracts only the essential information needed to determine paging priority (such as network identifier and signal characteristics) while filtering out redundant processing requirements for lower-priority networks. This selective extraction reduces processing burden while maintaining awareness of emergency communications.

Inventive Principle:

Principle #2Taking out (Extraction)

3Stability of the object's composition

If paging timing is synchronized across all networks, then coordination is improved, but emergency priority cannot be guaranteed

Engineering Contradiction:

Improvepaging timing coordinationVSAvoidemergency paging priority guarantee

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The patent introduces dynamic priority adjustment based on network identification and signal characteristics. Rather than fixed synchronized timing, the system dynamically determines reception priority by evaluating network type, signal strength, and emergency status indicators. This dynamic approach allows emergency paging from any network to override scheduled timing, ensuring priority guarantee while maintaining overall timing coordination through standardized protocols.

AI summary

A communication system includes a communication terminal, and a plurality of networks configured to perform radio communication with the communication terminal. A priority of at least one of a paging timing and a paging type is assigned to a paging to be transmitted from each of the plurality of networks. The communication terminal selects a corresponding one of the pagings to be received, based on the priority.
