Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection control techniques for terminal devices in wireless communication systems become excessively resource-intensive and time-consuming as the number of devices increases, leading to increased equipment costs and control delays, particularly in multilayer cell configurations.
Innovation Solution
A wireless communication system that clusters terminal devices into groups and allocates connection destinations based on evaluation index values, reducing the operational complexity by determining optimal base station devices for each cluster.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual connection control is performed for each terminal device, then connection control accuracy is improved, but the amount of operation and calculation resources required increases enormously
Solution Approach 1:
The patent merges multiple terminal devices into clusters and performs connection control at the cluster level rather than individually for each device. This combining approach maintains adequate connection control accuracy while dramatically reducing the computational burden and operational complexity associated with controlling each device separately.
Solution Approach 2:
The patent segments the large set of terminal devices into smaller clusters, making the connection control problem more manageable. By dividing the overall control task into cluster-level operations, the system reduces the complexity of calculating and managing connections for every individual device in the network.
2Reliability
If individual connection control is performed for each terminal device, then connection optimization is improved, but calculation time required increases
Solution Approach 1:
The patent combines multiple terminal devices into clusters and performs connection control operations at the cluster level. This merging strategy maintains connection optimization quality while significantly reducing the calculation time required, as the system evaluates fewer entities (clusters rather than individual devices) when determining optimal base station connections.
3Reliability
If comprehensive connection control is performed for all terminal devices, then communication quality is improved, but equipment cost increases
Solution Approach 1:
The patent merges terminal devices into clusters and performs connection control at the cluster level, which reduces the computational resources and equipment capabilities needed to achieve good communication quality. This approach maintains adequate communication quality while lowering the equipment cost burden that would result from implementing comprehensive individual device control.
4Measurement precision
If comprehensive connection control is performed for all terminal devices, then connection accuracy is improved, but control delay increases
Solution Approach 1:
The patent combines multiple terminal devices into clusters and performs connection control operations at the cluster level rather than individually. This merging approach maintains adequate connection accuracy while significantly reducing control delay, as the system processes fewer entities (clusters) and can更快地 determine and implement connection decisions.
