Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart devices connected to multiple networks, such as mobile and Wi-Fi, cannot accurately recognize and manage communication traffic for each application software, hindering network traffic control and leading to excessive mobile network usage.
Innovation Solution
A terminal device with communication control and instruction information management capabilities that acquire and retain statistical traffic information for each flow, associating it with application software and access networks, allowing for network traffic monitoring and optimization by switching to less congested networks when mobile traffic exceeds thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal device is connected to multiple communication networks simultaneously, then network connectivity and communication flexibility are improved, but the ability to recognize and manage traffic for each application on each network deteriorates
Solution Approach 1:
The patent segments traffic information management by creating separate flow tables for different communication networks (mobile network and Wi-Fi network). Each flow table independently manages traffic flows for applications on its respective network, enabling precise tracking of which application uses which network. This segmentation resolves the contradiction by maintaining detailed per-application-per-network traffic recognition while supporting multi-network connectivity.
2Ease of operation
If traffic information is managed centrally without network separation, then management simplicity is improved, but the precision of identifying application-specific network usage deteriorates
Solution Approach 1:
The control device divides traffic information into separate flow tables based on communication networks. Each flow table contains flow entries specific to one network type, making it easier to manage and identify which application uses which network without mixing traffic data. This structured segmentation maintains management simplicity while improving identification precision.
Solution Approach 2:
The patent introduces flow tables as intermediary structures between the control device and the mixed traffic streams from multiple networks. These flow tables act as mediators that organize, separate, and manage traffic information by network type, enabling precise application-network mapping while maintaining systematic and manageable control over multi-network traffic.
3Device complexity
If flow tables are not separated by communication network, then device complexity is reduced, but the ability to control application traffic per network deteriorates
Solution Approach 1:
The patent segments flow tables by communication network type, creating distinct flow tables for mobile networks and Wi-Fi networks. This segmentation enables independent control of application traffic on each network while maintaining a structured and organized device architecture. The separated flow tables provide the adaptability needed for network-specific traffic control without excessive complexity.
Solution Approach 2:
The patent implements dynamic flow table management where flow entries can be selectively created, modified, or deleted based on network conditions and application requirements. Each network's flow table can be independently adjusted, providing dynamic adaptability for traffic control while keeping the overall device structure manageable through modular organization.
