Solution Overview

Problem

Current wireless communication networks face low flexibility and inefficient frequency spectrum utilization due to the inability to adjust network configurations in real time, especially when traffic volumes change, leading to the need for buffer zones to prevent co-channel interference between different standards.

Innovation Solution

A cell processing method and apparatus that dynamically adjusts the communication standard of cells by measuring and comparing transmit powers using specific formulas to determine if cells can switch between standards, allowing shared cells to use a second standard and bufferzone cells to isolate interference, thereby optimizing frequency spectrum utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a buffer zone is set to isolate co-channel interference between different wireless communication standards, then interference isolation is improved, but frequency spectrum utilization deteriorates

Engineering Contradiction:
Improveinterference isolationVSAvoidfrequency spectrum utilization
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements dynamic cell standard switching where cells can transition between different communication standards (e.g., 2G/3G/4G) based on real-time traffic conditions and interference levels. This dynamic adjustment eliminates the need for static buffer zones while maintaining interference isolation, as cells can adapt their standard assignment to optimize both spectrum utilization and interference management.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of cells by dynamically adjusting which communication standard each cell uses. By monitoring traffic volume, interference levels, and other parameters, the system reassigns cells between standards to eliminate buffer zones, thereby improving frequency spectrum utilization while maintaining acceptable interference isolation through parameter-based decision making.

Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements a feedback mechanism where the system continuously monitors traffic volume, interference levels, and cell performance metrics. Based on this real-time feedback, the system automatically triggers re-planning operations and adjusts cell standard assignments without manual intervention. This closed-loop feedback system enables both easy operation through automation and real-time adaptability to changing network conditions.

Inventive Principle:

Solution Approach 2:

The system performs self-service by automatically detecting when re-planning is needed based on monitored parameters, executing the re-planning process autonomously, and adjusting cell configurations without requiring manual operator intervention. This self-service capability provides real-time adaptability while simplifying operations through automation of the entire re-planning workflow.

Inventive Principle:

Solution Approach 1:

The patent transforms the static cell-standard assignment into a dynamic system where cells can switch between different communication standards based on real-time conditions. The system maintains stability through controlled transition criteria and gradual adaptation, while simultaneously providing flexibility by allowing cells to change standards in response to traffic demands, interference levels, and network planning requirements.
