Communications Network Partitioning by Interference Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communications networks face challenges in managing inter-cell interference effectively, as a single operating mode may not optimize performance for all regions within the network, leading to suboptimal performance due to varying interference levels across different areas.
Innovation Solution
A system and method for configuring a communications network by partitioning it into regions based on interference levels, where a network device selects a starting communications controller and includes neighboring controllers if the average inter-cell interference exceeds a threshold, and sets operating modes according to interference classifications and metrics, allowing for tailored operating modes in different regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single operating mode is used across the entire communications network, then device complexity is reduced and ease of operation is improved, but network performance deteriorates due to varying interference levels in different regions
Solution Approach 1:
The communications network is divided into multiple regions based on interference characteristics. Each region is independently identified and configured with appropriate operating modes, allowing differentiated management of interference levels across the network while maintaining overall system performance
Solution Approach 2:
Different operating modes are assigned to different regions according to their specific interference conditions. High interference regions receive different configuration than low interference regions, optimizing performance locally while adapting to varying network conditions across the entire system
2Reliability
If the network is partitioned into multiple regions with tailored operating modes, then network performance and communication quality are improved, but device complexity and configuration difficulty increase
Solution Approach 1:
The system automatically identifies regions and determines appropriate operating modes based on measured interference levels. The network device autonomously configures regions without requiring manual intervention, reducing configuration complexity while maintaining optimized communication quality across different network areas

AI summary
A method for partitioning a communications network includes selecting, by a controller, a starting communications controller for a first region in the communications network according to an interference level. The method also includes including, by the controller, a first neighboring communications controller in the first region if an average inter-cell interference level of the starting communications controller and the first neighboring communications controller exceeds a first threshold and closing the first region if the average inter-cell interference level of the starting communications controller and the first neighboring communications controller fails to exceed the first threshold. The method further includes storing information about the first region in a memory.
