Solution Overview

Problem

In a mobile communication system, emergency information distribution areas are typically set based on administrative divisions, leading to situations where inappropriate emergency information may be distributed to communication devices within large communication cells that encompass multiple emergency information distribution areas.

Innovation Solution

A communication control apparatus that includes at least one processor to acquire emergency information relevant to the location of a communication station or device, generate local warning information specific to the vicinity of the communication station or device, and distribute this local warning information from the communication station to the communication device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If emergency information is distributed based on administrative divisions (municipalities), then comprehensive emergency coverage is achieved, but information relevance to specific communication devices deteriorates

Engineering Contradiction:

Improveemergency information coverageVSAvoidinformation relevance

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent segments the emergency information distribution by dividing the administrative division into smaller units based on communication cell boundaries. Each communication cell is treated as an independent distribution unit, allowing emergency information to be segmented and distributed to specific devices based on their location within the cell, thereby improving relevance while maintaining coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by generating location-specific emergency information for each communication cell rather than using uniform administrative division-based information. The system determines which communication cells are affected by the emergency and provides tailored information to devices in those specific locations, making the information more relevant to each device's local context.

Inventive Principle:

Principle #3Local quality

2Area of stationary object

If large communication cells are used, then communication coverage area is increased, but emergency information distribution accuracy deteriorates

Engineering Contradiction:

Improvecommunication cell coverageVSAvoidemergency information distribution accuracy

Core Design Contradiction:

Area of stationary objectVSMeasurement precision

Solution Approach 1:

The patent segments the large communication cell into smaller effective distribution units by using communication cell boundaries as dividers. Even though the physical cell coverage is large, the system segments the emergency information distribution based on the cell's internal structure and location data, enabling accurate targeting of devices within the large cell while maintaining the benefits of wide coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension to the distribution accuracy problem by using location information and communication cell boundary data as additional filtering criteria. Instead of relying solely on the physical coverage area of the cell, the system adds the dimension of location-based filtering to achieve accurate emergency information distribution even within large cells.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If emergency information distribution is simplified to single-area cells, then distribution ease is improved, but system flexibility deteriorates

Engineering Contradiction:

Improveemergency information distribution easeVSAvoidsystem adaptability to multiple areas

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent makes the emergency information distribution system universal by enabling it to handle multiple emergency information distribution areas simultaneously. The system can identify which communication cells fall within affected areas and automatically distribute appropriate information to devices in those cells, making the system adaptable to various emergency scenarios without requiring manual configuration for each case.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A communication control apparatus includes at least one processor that executes: acquiring, by an emergency information acquirer, emergency information regarding an emergency information distribution area where at least either a communication station capable of communicating with a communication device or the communication device is located; generating, by a local warning information generator, local warning information regarding the emergency information in a vicinity of at least either the communication station or the communication device, the vicinity being smaller than the emergency information distribution area; and distributing, by an information distributor, the local warning information from the communication station to the communication device.
