Solution Overview

Problem

The challenge is to suppress communication quality deterioration and power consumption during movement of mobile wireless station devices such as base station devices, which can be exacerbated by long movement distances or times, especially when the movement of these devices is required to adapt to changing spatial environments and congestion.

Innovation Solution

A wireless communication system with a control device that calculates and selects movement destination positions for mobile wireless station devices based on movement costs, ensuring the communication quality with terminal devices is maintained while minimizing power consumption by optimizing movement routes.

VSEngineering Contradiction Analysis

1Productivity

If the base station device is moved to adapt to changing spatial environments and congestion, then wireless resource utilization is improved and communication service quality is enhanced, but communication quality deteriorates during long movement and power consumption increases

Engineering Contradiction:

Improvewireless resource utilizationVSAvoidcommunication quality during movement

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The control device calculates multiple movement destination position candidates in advance before the mobile wireless station device moves, based on current terminal device positions and predicted future positions. This preliminary calculation allows the system to pre-determine optimal destinations that will maintain communication quality, avoiding the need for reactive movements that could cause quality deterioration during transit.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts movement control by calculating multiple candidate positions and selecting the optimal one based on real-time conditions. The control device determines movement destinations by considering both current and predicted terminal device positions, allowing the mobile wireless station device to adapt its movement dynamically while maintaining communication quality requirements.

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The control device calculates movement costs for multiple candidate positions using different parameters (distance, time, power consumption) and selects the optimal destination based on these parameters. By evaluating multiple parameters and choosing the best compromise, the system achieves good wireless resource utilization while minimizing power consumption for movement.
