Solution Overview
Problem
Existing audio communication systems using relaying devices are limited in managing a large number of transceivers, requiring alternative communication methods like SIP servers, which compromise instantaneousness and processing efficiency.
Innovation Solution
A network communication system with relaying devices operating in master and slave modes, allowing multiple relaying devices to communicate and manage terminal devices, enabling full-duplex group communication without echo through echo-canceling mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single relaying device manages transceivers, then communication management is simple, but the number of manageable transceivers is limited
Solution Approach 1:
The system divides the relaying function into multiple independent relaying devices, each managing a subset of transceivers. This segmentation allows the system to scale to accommodate a large number of transceivers while maintaining manageable complexity at each device level.
Solution Approach 2:
The patent introduces a hierarchical dimension to the network structure, with master and slave relaying devices operating at different levels. This dimensional organization enables the system to manage numerous transceivers by distributing control across multiple hierarchical layers rather than requiring a single centralized device.
2Quantity of substance
If SIP server communication method is used for transceivers exceeding the limit, then communication can be established, but instantaneousness is lost and processing becomes cumbersome
Solution Approach 1:
By segmenting the network into multiple relaying devices that can directly relay messages, the system avoids the time-consuming SIP server mediation process. Each relaying device maintains local knowledge of its subordinate transceivers, enabling instantaneous direct communication without external server intervention.
Solution Approach 2:
Relaying devices pre-establish knowledge of subordinate transceivers and their relationships through the master-slave hierarchy setup. This preliminary action enables immediate direct communication when needed, eliminating the time loss associated with server-mediated connection establishment.
3Adaptability or versatility
If multiple relaying devices are linked to manage large numbers of terminal devices, then full-duplex group communication is enabled, but system complexity increases
Solution Approach 1:
The patent merges the relaying functions of multiple devices into a coordinated master-slave hierarchy, where slave devices relay communications through the master. This merging approach enables full-duplex group communication across the network while maintaining structured complexity that is easier to manage than fully distributed peer-to-peer relaying.
Solution Approach 2:
The master relaying device acts as an intermediary between slave relaying devices and the network, coordinating communications and managing the hierarchy. This intermediary role simplifies the overall system structure by providing a central coordination point, reducing the complexity that would arise from direct peer-to-peer interactions between multiple equal-status relaying devices.

AI summary
[Problem] To provide an audio communication system wherein a relaying device is connected to terminal devices, which are communication devices, via a communication network and wherein the relaying device is caused to manage the group of the terminal devices.[Solution] An audio communication system comprises: a master relaying device; one or more slave relaying devices connected to the master relaying device via a communication network; and one or more terminal devices connected to each relaying device via a communication network. Each slave relaying device transfers, to the master relaying device, audio signals received from the terminal device in charge of the slave relaying device. The master relaying device transfers the audio signals, which were received from each slave relaying device, to the slave relaying devices other than that slave relaying device.
