Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Call mutings occur during handovers between base stations in network environments, indicating inefficiencies or errors within specific areas, which are not necessarily UE-specific and affect service quality.
Innovation Solution
A method and system that divide a network cluster into grids, determine call muting percentages, generate call muting polygons for areas with high muting percentages, and assign priority levels based on unique user distributions to identify and optimize these areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If call muting detection is performed across the entire network cluster, then the coverage area is large and comprehensive monitoring is achieved, but the complexity of analysis and identification increases significantly
Solution Approach 1:
The network cluster is divided into multiple grids, where each grid represents a manageable geographic unit. This segmentation allows the system to process and analyze call muting data in smaller, more tractable units rather than attempting to analyze the entire network cluster at once, thereby reducing analysis complexity while maintaining comprehensive coverage.
Solution Approach 2:
The patent introduces a geographic dimension by mapping call muting events to specific spatial locations and generating polygons that represent affected areas. This transforms the problem from a purely network-performance dimension to a spatial-geographic dimension, enabling more intuitive identification and analysis of call muting patterns.
2Measurement precision
If the network cluster is divided into many small grids, then the precision of identifying call muting areas is improved, but the quantity of grids and processing overhead increases
Solution Approach 1:
The system applies different analysis thresholds and priorities to different grids based on their local characteristics, such as user density and call muting frequency. This allows for more precise identification of problematic areas while avoiding unnecessary processing in grids with low or normal call muting percentages, thereby balancing precision with processing efficiency.
3Reliability
If call muting polygons are generated for all grids with high muting percentages, then complete identification of affected areas is achieved, but the quantity of polygons and data processing increases
Solution Approach 1:
The system uses a predetermined call muting percentage threshold to filter and prioritize grids for polygon generation. By changing the parameter of call muting percentage and comparing it against the threshold, the system efficiently identifies only those grids that require further attention, reducing the number of polygons generated while maintaining reliable identification of significant call muting areas.
4Reliability
If area-specific optimizations are implemented based on call muting polygons, then service quality in affected areas is improved, but the complexity of implementing targeted optimizations increases
Solution Approach 1:
The patent enables different optimization strategies to be applied to different call muting polygons based on their specific characteristics, such as location, size, and call muting severity. This local quality approach allows network operators to tailor optimizations to specific problem areas rather than implementing uniform network-wide changes, improving service quality in affected areas while managing implementation complexity through targeted interventions.

AI summary
A method of identifying call muting areas includes dividing a network cluster into a plurality of grids, determining a call muting percentage of at least one first grid of the plurality of grids, determining whether the call muting percentage of the at least one first grid is greater than a predetermined call muting percentage threshold, and generating at least one call muting polygon including at least a portion of the at least one first grid based on determining that the call muting percentage of the at least one first grid is greater than the predetermined call muting percentage threshold.
