Solution Overview

Problem

Conventional techniques fail to properly configure network infrastructure for non-stationary radio base stations, making it difficult to achieve flexible access to telecommunications networks, especially in areas with insufficient or unavailable data connectivity.

Innovation Solution

A method and device for operating a movable radio base station that changes modes to optimize radio parameters based on observed, measured, or predicted needs, allowing for flexible wireless access and network planning, including adjusting parameters such as carrier frequency, transmission power, and antenna tilt angles, and exchanging information with neighboring stations to manage radio interference and handovers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional techniques are used to configure network infrastructure, then stationary base station deployment is straightforward, but flexible access for non-stationary radio base stations is difficult or impossible

Engineering Contradiction:
Improveflexible accessVSAvoidnetwork configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by enabling the movable radio base station to dynamically change its operational mode between master and slave modes based on real-time network conditions and mobility requirements. This dynamic adaptation allows the system to flexibly reconfigure network infrastructure without requiring complex static planning for each possible movement scenario

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes parameter changes by transitioning the movable radio base station between different operational modes (master mode with full functionality vs. slave mode with reduced functionality). These mode changes involve adjusting key parameters such as control plane connectivity, user plane capabilities, and synchronization settings, enabling flexible adaptation to different deployment scenarios

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the movable radio base station changes modes frequently to adapt to user demands, then flexible access is improved, but network configuration complexity increases

Engineering Contradiction:
Improvemode flexibilityVSAvoidparameter configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms where the movable radio base station continuously monitors network conditions, user equipment density, and service requirements to automatically determine when mode transitions are necessary. This feedback-driven approach reduces unnecessary mode changes and simplifies configuration management by basing decisions on actual network state rather than pre-planned scenarios

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The movable radio base station performs self-configuration when transitioning between modes, automatically adjusting its operational parameters and connectivity settings without requiring manual reconfiguration. The station autonomously manages its master/slave mode transitions and associated parameter changes, reducing the burden on network operators

Inventive Principle:
Principle #25Self-service
