Solution Overview

Problem

Existing communication systems face challenges in efficiently allocating communication resources to monitor areas of high traffic hazard without exceeding the capacity of a single base station, especially when multiple hazardous areas arise simultaneously within its coverage.

Innovation Solution

A communication resource allocation device determines hazard levels for monitoring areas based on past hazardous behaviors and environmental factors, allocating resources accordingly to prioritize high-risk zones.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If real-time monitoring of all areas within base station coverage is performed to identify hazardous areas, then the accuracy and timeliness of hazard detection is improved, but the communication resource consumption increases significantly beyond available capacity

Engineering Contradiction:
Improvehazard detection accuracyVSAvoidcommunication resource consumption
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent applies local quality by determining hazard levels specifically for monitoring target areas rather than uniformly across the entire base station coverage area. The base station identifies monitoring target areas based on vehicle concentration and communication quality, then performs hazard level determination only within these localized regions. This selective approach concentrates communication resources on areas where they are most needed, resolving the contradiction between comprehensive monitoring accuracy and resource consumption.

Inventive Principle:
Principle #3Local quality

2Speed

If monitoring target areas are dynamically specified in real-time within base station coverage, then the responsiveness to emerging hazards is improved, but the communication resources required for continuous monitoring exceed base station capacity

Engineering Contradiction:
Improvehazard response speedVSAvoidcommunication resource consumption
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

The patent applies preliminary action by performing hazard level determination based on past hazardous behaviors within a reference period before real-time dynamic specification of monitoring target areas. The base station uses historical hazard data to pre-identify areas that are likely to require monitoring, then focuses real-time resources on these pre-identified areas. This approach enables responsive hazard detection while limiting communication resource consumption to pre-selected monitoring zones rather than requiring continuous full-coverage monitoring.

Inventive Principle:
Principle #10Preliminary action

3Area of stationary object

If multiple hazardous areas are monitored simultaneously with high priority communication resources, then the coverage of safety monitoring is improved, but the limited base station resources become insufficient to support all areas

Engineering Contradiction:
Improvemonitoring coverage areaVSAvoidavailable communication resources
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The patent applies segmentation by dividing the base station coverage area into multiple monitoring target areas based on vehicle concentration and communication quality metrics. Each monitoring target area is independently evaluated for hazard level and allocated communication resources proportionally. This segmentation allows the system to manage multiple hazardous areas simultaneously by distributing limited communication resources across divided zones rather than attempting to monitor all areas uniformly, resolving the contradiction between monitoring coverage and available resources.

Inventive Principle:
Principle #1Segmentation

AI summary

A communication resource allocation device (10) identifies a hazardous behavior that may cause a traffic accident and has occurred in each of monitoring target areas included in a communication area of a base station (20) in a past reference period, so as to determine a hazard level for each of the monitoring target areas. The communication resource allocation device (10) allocates communication resources to each of the monitoring target areas based on the determined hazard level. The communication resource allocation device (10) distributes information to a roadside device (30) and an in-vehicle device (40) in each of the monitoring target areas, using the allocated communication resources.
