Dead Zone Prediction for Proactive Wireless Connection Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in local 5G (L5G), areas known as dead zones where radio waves cannot reach due to blocking objects cause communication quality deterioration and interruptions when terminals enter these zones.
Innovation Solution
A communication system with a control device that predicts a terminal's entry into a dead zone by collecting location and velocity information, allowing for proactive switching to a different connection destination or establishing a duplication line to maintain communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high frequency bands (28 GHz millimeter wave) are used for 5G/L5G communication, then ultra-high speed communication is achieved, but dead zones occur where radio waves cannot reach due to blocking objects
Solution Approach 1:
The control device performs preliminary actions by predicting future terminal locations and identifying potential dead zone entries before they occur. The system calculates future positions based on current location and movement information, determines whether the terminal will enter dead zones, and executes connection switching in advance, thereby preventing communication quality deterioration before it happens.
2Adaptability or versatility
If the terminal moves through areas with blocking objects, then coverage flexibility is improved, but communication quality deteriorates due to dead zone entry
Solution Approach 1:
The system implements feedback mechanisms by continuously acquiring terminal location information and movement status, using this feedback to predict future positions, and adjusting connection destinations based on predicted dead zone entries. This closed-loop feedback enables the system to adapt to terminal movement while maintaining communication quality.
3Device complexity
If connection switching is performed reactively after dead zone entry, then system complexity is reduced, but communication interruption occurs
Solution Approach 1:
The control device performs preliminary actions by predicting future terminal locations and identifying potential dead zone entries before they occur. The system calculates future positions based on current location and movement information, determines whether the terminal will enter dead zones, and executes connection switching in advance, thereby preventing communication quality deterioration before it happens.

AI summary
A communication system includes a terminal that communicates with a base station wirelessly; and a control device, in which the terminal includes a transmitter that transmits information on a location of the terminal, and the control device includes a processor; and a memory that includes instructions, which when executed, cause the processor to execute the following steps: acquiring the information on the location of the terminal, predicting a future location of the terminal based on the information on the location of the terminal and determining whether the terminal is to enter a dead zone by comparing the future position with the dead zone, and executing control for switching a connection destination of the terminal when the determining determines that the terminal is to enter the dead zone.
