Base Station Warning Shutdown for Resource Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public warning systems (PWS) face resource congestion in base stations when broadcasting multiple warnings, leading to inefficient resource utilization and reduced data communication capabilities.
Innovation Solution
A communication device and method that determine a shutdown of warnings based on congestion conditions in base stations by comparing resource usage rates with thresholds, allowing for efficient resource allocation between warning broadcasts and data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station broadcasts multiple warnings periodically, then the warning delivery reliability is improved, but the resource usage rate increases causing congestion
Solution Approach 1:
The patent applies dynamics by making the warning broadcast configuration changeable based on real-time base station resource status. The controller dynamically adjusts warning broadcast parameters (such as repetition period or broadcast frequency) according to the measured resource usage rate, transitioning between different broadcast modes to balance reliability and resource efficiency.
Solution Approach 2:
The patent changes operational parameters by modifying warning broadcast characteristics based on resource availability. When resource usage rate is high, the system changes parameters to reduce broadcast frequency or extend repetition periods, thereby reducing resource consumption while maintaining essential warning delivery capability.
2Reliability
If the base station increases warning broadcast frequency, then the warning coverage is improved, but the data communication capability deteriorates
Solution Approach 1:
The system dynamically adjusts warning broadcast frequency based on real-time resource status measurements. The controller monitors resource usage rate and accordingly modulates the broadcast frequency, reducing it when resources are constrained to preserve data communication capability, and increasing it when resources are available to ensure comprehensive warning coverage.
Solution Approach 2:
The patent implements feedback by measuring the base station's resource usage rate and using this information to control warning broadcast behavior. The controller continuously monitors resource status and adjusts broadcast parameters in response, creating a closed-loop system that balances warning coverage with data communication performance.

AI summary
A communication device serving as a base station configured to notify a mobile station of a warning or an upper device of the base station includes a controller configured to shut down the warning, notified from the base station based on warning information, upon determining the congestion condition of the base station, and a communication part configured to transmit the information regarding a shutdown of warning. Herein, the controller compares a first threshold with a resource usage rate or the amount of resources in the base station, thus determining the congestion condition of the base station. Additionally, the controller compares a second threshold with the warning information so as to determine a shutdown of warning. The second threshold can be set based on the resource usage rate or the type of the base station.
