Solution Overview

Problem

The complexity of dynamically changing connections in mobile communication systems increases configuration complexity, and existing solutions do not efficiently allocate resources across service areas with differing traffic peaks.

Innovation Solution

A mobile communication system with first and second radio units, each serving half of the traffic peak in separate areas, connected to a first and second radio control unit, which are constantly connected to an upper controller, allowing for efficient resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If resources are provided according to traffic peak in each service area, then traffic handling capability is improved, but resource waste occurs during low traffic periods

Engineering Contradiction:
Improvetraffic handling capabilityVSAvoidresource waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent merges multiple service areas into a single coverage area served by one base station, allowing resources to be shared across different service areas with different traffic patterns. This enables resources to handle peak traffic from any single service area without requiring separate peak-capacity resources for each area, thereby improving traffic handling capability while reducing overall resource requirements and waste during low traffic periods.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the antenna of each cell is selectively connected to upper controllers according to traffic amounts, then resource sharing among service areas is improved, but configuration complexity increases

Engineering Contradiction:
Improveresource sharing capabilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the dynamic connection switching function from the system configuration, eliminating the need for selective antenna connections to multiple upper controllers. By providing a single base station that serves multiple service areas, the system removes the complexity of dynamic connection management while maintaining resource sharing capabilities across different service areas with varying traffic patterns.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If a single base station serves multiple service areas, then resource allocation is simplified, but coverage area increases

Engineering Contradiction:
Improveresource allocation complexityVSAvoidcoverage area
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The patent segments a single large coverage area into multiple service areas with different traffic characteristics, all served by one base station. This segmentation allows the system to maintain a manageable coverage area while simplifying resource allocation, as the base station can dynamically allocate resources based on the traffic needs of each segmented service area without requiring separate base stations for each area.

Inventive Principle:
Principle #1Segmentation
