Relay Selection for Session Quality Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in optimizing content data transmission quality across multiple terminals using relay apparatuses, as they lack a systematic approach to select the most suitable relay apparatuses based on service quality, leading to inconsistent communication experiences.
Innovation Solution
A management system that determines transmission quality between terminals and selects appropriate relay apparatuses to ensure optimal communication conditions by evaluating the service quality of available relay apparatuses and connecting terminals accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay apparatuses are selected without systematic quality evaluation, then device complexity is reduced, but transmission quality and reliability deteriorate
Solution Approach 1:
The management system performs preliminary evaluation of relay apparatus qualities before content data transmission begins. The determination unit assesses transmission qualities of multiple relay apparatuses in advance, and the selection unit pre-selects the most suitable relay apparatus based on this evaluation, ensuring high transmission quality without adding operational complexity during actual data transfer
Solution Approach 2:
The management system automatically evaluates and selects relay apparatuses without requiring manual intervention. The determination unit independently assesses transmission qualities by examining network conditions and relay apparatus capabilities, while the selection unit autonomously chooses the optimal relay apparatus, making the system self-sufficient and eliminating the need for complex manual configuration
2Reliability
If multiple relay apparatuses are evaluated and selected based on service quality, then transmission quality improves, but processing time increases
Solution Approach 1:
The selection unit does not need to evaluate all possible relay apparatuses in detail. Instead, it performs partial evaluation by assessing key transmission quality parameters of available relay apparatuses and selects the most suitable one based on this limited but sufficient information, reducing processing time while maintaining transmission quality
Solution Approach 2:
The determination unit evaluates relay apparatuses based on changeable parameters such as current network conditions, available bandwidth, and transmission quality metrics. By dynamically adjusting evaluation criteria based on these parameters, the system can quickly identify suitable relay apparatuses without exhaustive evaluation, balancing selection speed with transmission quality
3Ease of operation
If relay apparatus selection is automated based on transmission quality, then ease of operation improves, but device complexity increases
Solution Approach 1:
The management system performs multiple functions using the same core components. The determination unit not only evaluates transmission quality but also gathers network information and assesses relay apparatus capabilities. The selection unit both selects relay apparatuses and manages transmission sessions, reducing overall system complexity while maintaining ease of operation through multi-functionality
