Transmission Management System Load Distribution via Relay Device Recognition
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 difficulties in determining which relay device to connect new participants to, as multiple management systems cannot recognize the relay device used for communication control.
Innovation Solution
A transmission management system that receives communication control information to allow another management system to execute control requests, enabling the connection of new terminals to the appropriate relay device even if the primary system cannot, by transmitting control request information based on received communication control information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple transmission management systems are provided to disperse loads, then the load on each management system is reduced, but the management systems cannot recognize which relay device is used when communication is controlled by another management system
Solution Approach 1:
The patent introduces communication control information as an intermediary that carries relay device identification between management systems. When a management system cannot determine the relay device, it requests communication control information from another management system that controls the relay device, enabling indirect recognition through this information mediator.
Solution Approach 2:
The patent implements a feedback mechanism where management systems exchange communication control information about relay devices. When a management system needs to determine relay device usage, it receives feedback from other management systems that control the relay devices, allowing the system to make informed decisions about new terminal connections.
2Device complexity
If a single transmission management system controls all communication starts, then relay device assignment is simplified, but the load on the management system significantly increases when multiple communication starts occur simultaneously
Solution Approach 1:
The patent divides the centralized control function into multiple management systems that each control specific relay devices. Instead of one management system handling all communication starts, the system is segmented into multiple independent management systems that can operate autonomously, distributing the processing load while maintaining clear control boundaries.
Solution Approach 2:
The patent adds a new dimension of communication control information exchange between management systems. This allows the system to transition from a single-dimension centralized control model to a multi-dimension distributed control model where management systems can query each other about relay device status and control responsibilities.
3Reliability
If one relay device is selected from multiple candidates for each television conference, then the load on relay devices is dispersed, but determining which relay device to connect new participants to becomes complex when multiple management systems are involved
Solution Approach 1:
The patent uses feedback mechanisms where management systems query other management systems to obtain communication control information about which relay device is currently controlling a television conference. This feedback allows the system to make informed decisions about connecting new participants to the appropriate relay device without complex manual determination.
Data Source
AI summary
A transmission management system receives, when a terminal and a relay device is connected, domain information that indicates a management system capable of executing control associated with start of communication using the relay device. The management system can allow another management system to execute control based on the domain information even if the management system cannot execute the control.
