Solution Overview

Problem

When multiple movable base stations are deployed in an area, concentrated connection destinations can lead to communication congestion due to traffic overload on specific base stations.

Innovation Solution

An information processing device determines the installation position of movable base stations and their connection destinations based on the reception strength of radio signals from existing base stations, using mesh radio information to optimize installation and connection within the network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If connection destination base stations are concentrated in a specific area, then installation complexity is reduced, but communication congestion occurs due to traffic overload

Engineering Contradiction:

Improveinstallation complexityVSAvoidcommunication congestion

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent applies local quality by determining optimal connection destinations for movable base stations based on their specific installation positions and local traffic conditions. Each movable base station is assigned to a fixed base station that best serves its local area, rather than concentrating all connections at a single location. This distributes traffic load across multiple fixed base stations while maintaining simple installation procedures.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If movable base stations are deployed to accommodate more users, then user coverage is improved, but traffic concentration on specific base stations causes communication congestion

Engineering Contradiction:

Improveuser coverageVSAvoidcommunication congestion

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the network into multiple fixed base stations, each serving as a connection destination for specific movable base stations. This segmentation distributes the traffic load from multiple movable base stations across several fixed base stations rather than concentrating it on a single station, thereby maintaining expanded user coverage while preventing communication congestion.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the number of fixed base stations is increased to distribute traffic, then communication congestion is reduced, but installation and operation costs increase

Engineering Contradiction:

Improvecommunication congestionVSAvoidinstallation and operation costs

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent utilizes the dynamic nature of movable base stations to achieve traffic distribution without permanently installing additional fixed base stations. By strategically assigning movable base stations to different fixed base stations based on their positions and traffic patterns, the system dynamically distributes load across existing infrastructure, reducing congestion without the need for expensive additional permanent installations.

Inventive Principle:

Principle #15Dynamics

AI summary

A determination method of determining an installation position of a movable base station and a connection destination base station, executed by an information processing device including a memory and a processor, includes: determining a mesh in which the movable base station can be installed, and a base station to which the movable base station can be connected in the mesh, based on a reception strength of a radio signal from each of one or more base stations in each of one or more meshes.
