Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for determining site position priority orders for new radio base stations are ambiguous, time-consuming, and lack reliability, especially when dealing with a large number of small cell sites, and do not adequately consider business effectiveness or co-siting/RAN sharing scenarios.
Innovation Solution
A site position priority order determination device and method that calculates a weighted sum of nonattainment and estimated attainment degrees of service quality, cell load tightness, cell capacity supply, and competing company dominance, using a radio communication apparatus to measure and transmit data with existing base stations, to determine priority orders based on measurable indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual calculation of nonattainment degree and estimated attainment degree by person in charge of site survey is used, then reliability of priority order determination is improved, but time required to create site position priority order list increases
Solution Approach 1:
The determination process is segmented into multiple evaluation indicators (throughput nonattainment degree, cell load tightness degree, capacity supply degree, competing company dominance degree) that are calculated and evaluated separately, then combined through weighted summation. This allows systematic and reliable evaluation while enabling automated processing to reduce time consumption.
Solution Approach 2:
The patent transforms subjective manual assessment into objective parameter-based evaluation by defining specific measurable indicators (throughput values, cell load percentages, capacity ratios) with assigned weights. This parameterization enables both reliable determination and automated computation to reduce time requirements.
2Measurement precision
If comprehensive manual evaluation considering multiple factors is performed, then accuracy of priority order determination is improved, but complexity of determination process increases
Solution Approach 1:
The complex evaluation process is divided into distinct modular indicators: throughput nonattainment degree calculation, cell load tightness degree calculation, capacity supply degree calculation, and competing company dominance degree calculation. Each module handles a specific aspect, improving accuracy while making the overall process more manageable and less complex through structured organization.
Solution Approach 2:
Multiple evaluation factors are converted into standardized parameters with defined calculation formulas and weight coefficients. This parameterization maintains comprehensive evaluation accuracy while enabling systematic processing that reduces operational complexity.
3Area of stationary object
If site survey is conducted for large number of small cell sites, then coverage of network design is improved, but time required for site survey increases
Solution Approach 1:
The patent establishes a standardized parameter-based evaluation system that can be uniformly applied across numerous small cell sites. By defining measurable indicators (throughput, cell load, capacity ratios) with consistent calculation methods and weight assignments, the system enables efficient processing of large numbers of sites while maintaining comprehensive coverage evaluation.
Solution Approach 2:
The evaluation methodology is designed as a replicable framework that can be copied and applied to each small cell site candidate. The standardized indicators and weighted summation approach allow consistent evaluation across multiple sites through systematic replication of the assessment process, reducing time requirements compared to individualized manual surveys.
4Productivity
If automated calculation system is implemented, then productivity of site position priority order list creation is improved, but reliability of determination may deteriorate
Solution Approach 1:
The patent defines explicit parameters with standardized calculation formulas (e.g., nonattainment degree = (target throughput - measured throughput) / target throughput × 100%, cell load tightness degree = (cell load - permissible cell load) / permissible cell load × 100%). These parameter definitions ensure automated calculations produce reliable and consistent results while maintaining high productivity through computational efficiency.
