Solution Overview

Problem

Existing technologies face challenges in efficiently controlling the movement of movable base station devices to suppress deterioration in quality and increase in power consumption during the movement of the movable base station device, particularly when the movement distance or time required is long, leading to potential communication quality deterioration and increased power consumption.

Innovation Solution

A wireless communication system is implemented with a control device that predicts future positions of terminal devices and calculates movement destination positions for mobile wireless station devices, such as base station devices, to minimize movement costs and maintain communication quality by selecting optimal movement paths based on predicted positions and required quality criteria.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the base station device is moved to provide appropriate wireless communication service, then wireless resources are effectively utilized, but communication quality deteriorates during movement and power consumption increases

Engineering Contradiction:

Improvewireless resource utilizationVSAvoidcommunication quality

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The control device predicts future positions of terminal devices and pre-calculates optimal movement destination positions for mobile base station devices before actual movement occurs. This allows the system to plan movements that maintain communication quality while achieving effective resource utilization, rather than reacting to conditions after they arise.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically determines movement destination positions based on predicted terminal device positions and current network conditions. The control device evaluates multiple possible movement paths and selects optimal combinations that balance communication quality requirements with resource utilization benefits, allowing flexible adaptation to changing conditions during movement.

Inventive Principle:

Principle #15Dynamics

Solution Approach 1:

The control device performs preliminary calculations of movement costs and predicts future positions before initiating movement. By pre-evaluating multiple movement scenarios and their associated energy consumption, the system selects optimal movement paths that achieve effective resource utilization while minimizing power consumption, rather than making reactive movement decisions that waste energy.

Solution Approach 1:

The control device calculates predicted positions of terminal devices and determines optimal movement destination positions in advance. By planning movements that account for predicted terminal positions and selecting optimal paths, the system achieves the desired communication quality at the destination while minimizing the time required to get there, rather than making lengthy unplanned movements.

Inventive Principle:

Solution Approach 2:

The system dynamically optimizes movement parameters including destination selection, path routing, and timing based on real-time conditions and predictions. The control device evaluates multiple possible movement scenarios and selects combinations that achieve optimal communication quality while minimizing movement time, allowing the system to adapt to changing conditions during the movement process.
