Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cell-based network management is used to manage tens of thousands of cells with dynamic characteristics, then network coverage and service capability are improved, but management costs and complexity increase significantly

Engineering Contradiction:

Solution Approach 1:

The patent segments the network management function by introducing a dedicated network management device that separates management plane functions from user plane functions. This segmentation allows the management device to handle dynamic characteristics of cells through automated algorithms while base stations focus on service delivery, thereby reducing overall management complexity while maintaining service capability.

Inventive Principle:

Solution Approach 2:

The patent introduces a network management device as an intermediary between the core network and base stations. This intermediary automatically collects performance data, analyzes dynamic characteristics, and generates configuration commands, thereby reducing the burden on operators to manually manage tens of thousands of cells while maintaining adaptability to changing network conditions.

Inventive Principle:
