Relay Device Selection for Videoconference Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing videoconference systems lack efficient methods for selecting a relay device that takes into account the location of communication terminals, leading to potential inefficiencies in load distribution and scalability.
Innovation Solution
A control system that includes multiple relay devices and control apparatuses, where each apparatus stores relay device identification information and selects an appropriate relay device based on the terminal's location for content data relay, ensuring optimal connection and load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plurality of control apparatuses are provided to manage videoconference sessions, then the scalability and load distribution capability are improved, but the relay device selection may become independent of terminal location, reducing communication efficiency
Solution Approach 1:
The patent applies local quality by making relay device selection dependent on terminal location. Each control apparatus selects relay devices based on the geographic or network location of connecting terminals, ensuring that terminals in specific regions connect to appropriately located relay devices. This location-aware selection optimizes communication efficiency while maintaining the scalability benefits of multiple control apparatuses.
2Productivity
If relay device selection is made based on terminal location, then communication efficiency and load distribution are improved, but the control system complexity increases
Solution Approach 1:
The patent implements self-service by enabling control apparatuses to autonomously select relay devices based on terminal location information without requiring centralized coordination. Each control apparatus independently manages relay selection for its connected terminals, simplifying the overall control architecture while achieving location-optimal relay assignment. This distributed self-service approach reduces control system complexity compared to centralized management.

AI summary
A plurality of control apparatuses each stores, in a memory, relay device identification information for identifying one or more relay devices of a plurality of relay devices available for selection by the control apparatus, and selects, in response to connection of a first communication terminal to the control apparatus, one of the one or more relay devices having the relay device identification information stored in the memory as a first relay device to be connected to the first communication terminal to relay content data for the first communication terminal under control of the control apparatus.
