Wireless Parameter Control for Cell Coverage Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for balancing traffic loads between wireless cells do not explicitly consider the throughput of wireless terminals, leading to suboptimal throughput optimization, and rely on trial and error for adjusting wireless quality offset parameters, which can result in local optimal solutions.
Innovation Solution
A wireless parameter control apparatus that predicts the serving cell and communication speed index of wireless terminals by assuming changes in wireless quality offset parameters, allowing for controlled adjustments to cell coverage to improve throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traffic load balancing is performed by adjusting coverage of wireless cells, then traffic load balance between cells is improved, but throughput characteristic of wireless terminals deteriorates
Solution Approach 1:
The patent predicts the serving cell and throughput of wireless terminals in advance by simulating offset value changes before actually applying them. This preliminary prediction allows the system to select offset adjustments that will improve throughput while achieving load balance, rather than relying on trial-and-error adjustments that may degrade performance.
Solution Approach 2:
The patent uses predicted throughput values as feedback to guide the selection of offset values. By comparing predicted throughput for different offset configurations, the system can identify the optimal offset values that simultaneously achieve load balancing and maintain or improve throughput characteristics.
2Adaptability or versatility
If trial and error method is used to adjust wireless quality offset parameters, then coverage adjustment flexibility is improved, but control precision deteriorates
Solution Approach 1:
The patent performs preliminary prediction calculations to determine the exact offset values that will achieve desired coverage adjustments and throughput optimization. This eliminates the need for trial-and-error adjustments by providing precise predicted outcomes for each potential offset configuration.
Solution Approach 2:
The patent replaces the mechanical trial-and-error adjustment process with a prediction-based calculation system. Instead of physically adjusting offset parameters and measuring results iteratively, the system uses prediction algorithms to directly determine the optimal offset values, substituting computational analysis for empirical adjustment.

AI summary
A wireless parameter control device comprises: a serving cell prediction unit (11) which predicts a wireless cell which is a connection destination of a first wireless terminal within a first wireless cell upon assuming that an offset value which is added to the wireless quality which the first wireless terminal measures for each wireless cell is changed to a prescribed candidate value; a communication speed index prediction unit (12) which predicts a communication speed index of the first wireless terminal upon assuming that the offset value is changed to the prescribed candidate value and/or a communication speed index of a second wireless terminal within a second wireless cell which is present in the periphery of the first wireless cell; and a coverage control unit (13) which, on the basis of the result of the prediction of the communication speed index, controls the coverage of the first wireless cell and/or the coverage of the second wireless cell.
