Cellular Neighbor Relation Prioritization for Irrelevant Link Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular communication networks face challenges in efficiently assessing and configuring neighbour relations, leading to inefficient resource usage and potential service degradation due to irrelevant neighbour relations.
Innovation Solution
A combined list of neighbour relations is used, incorporating priority indices from both the perspective of a first cell and its target cells, allowing for the removal of irrelevant relations while preserving important ones, thereby enhancing network efficiency and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional neighbour relation assessment methods are used, then network configuration is maintained, but network efficiency deteriorates due to irrelevant neighbour relations
Solution Approach 1:
The patent combines neighbour relation assessments from multiple base stations into a unified evaluation. By merging the neighbour relation lists and priority indices from different base stations, the system creates a comprehensive view of neighbour relations, allowing identification of relations that are irrelevant from multiple perspectives and enabling more efficient network configuration while maintaining service quality.
2Productivity
If neighbour relations are optimized to remove irrelevant relations, then network performance improves, but network complexity increases due to dual-perspective assessment
Solution Approach 1:
The patent performs preliminary assessment of neighbour relations by collecting and evaluating priority indices from multiple base stations before making optimization decisions. This preliminary action includes generating combined neighbour relation lists and identifying irrelevant relations in advance, which simplifies the subsequent optimization process and reduces the complexity of real-time decision-making.
3Loss of information
If dual-perspective neighbour relation assessment is implemented, then irrelevant relations are identified, but information processing requirements increase
Solution Approach 1:
The patent extracts only the essential information needed for neighbour relation assessment - specifically the priority indices from each base station's perspective. By taking out and focusing on these key parameters rather than processing all available neighbour relation data, the system reduces information processing requirements while maintaining accurate identification of relevant and irrelevant neighbour relations.
