Relay Device Selection Distributes Communication Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional television conference systems face increased load on a single transmission management system when multiple communication starts occur simultaneously, leading to inefficiencies in relay device management.
Innovation Solution
A relay device selection device that manages communication control information to distribute the load across multiple transmission management systems by selecting an appropriate relay device based on priority and domain information, allowing any management system indicated by the relay device ID to execute communication control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one transmission management system is used to control the start of communication, then the system structure is simple, but the load on the transmission management system significantly increases when multiple communication starts occur simultaneously
Solution Approach 1:
The patent segments the transmission management function by associating each relay device with a specific transmission management system via communication control information. This allows the load of controlling communication starts to be divided across multiple transmission management systems rather than concentrated on a single system, resolving the contradiction between simple system structure and manageable load.
2Quantity of substance
If one relay device is selected from among a plurality of candidate relay devices every television conference, then the load on relay devices is dispersed, but a single transmission management system becomes a bottleneck when multiple communication starts occur simultaneously
Solution Approach 1:
The patent introduces communication control information as an intermediary that links relay devices to transmission management systems. This intermediary mechanism enables multiple transmission management systems to participate in communication start control, preventing any single system from becoming a bottleneck while maintaining efficient relay device selection.
3Quantity of substance
If multiple transmission management systems are used to distribute load, then the load on individual systems is reduced, but the system complexity increases
Solution Approach 1:
The patent implements a universal communication control information structure that can be applied across multiple transmission management systems. This multi-functional approach allows the same mechanism to operate consistently across different systems, enabling load distribution without proportionally increasing system complexity.

AI summary
A selection device 80 outputs domain information that indicates a management system 50 capable of executing control associated with the start of communication using a selected relay device 30. Consequently, the control associated with the start of communication using the selected relay device 30 can be executed by any of the management systems 50 indicated by the domain information. That is, a load based on the control of the start of communication can be dispersed into a plurality of management systems 50, and thus there is an effect of reducing a load to the management systems 50.
