Relaying Device for Voice Communication Area Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a single building with multiple business companies, establishing a wireless voice communication system that allows separate communication systems for each company while minimizing costs and complexity is challenging, as existing systems require separate installations and management for each company, leading to high introduction costs and complex management.
Innovation Solution
A voice communication system that uses a relaying device connected to terminal devices via a network, managing communication based on device belonging and position, allowing multiple virtual voice communication systems to be created within a single system, with a relaying device, wireless access points, and a control unit that determines the appropriate section system for voice signal transfer based on area information and identification codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single wireless communication system is introduced for all companies in a building, then the introduction cost is reduced, but electric waves reach other companies causing interference and communication security issues
Solution Approach 1:
The patent divides the building into multiple areas (first area, second area, etc.) and assigns different repeater systems to each area. Each repeater system operates independently within its designated area, preventing electric wave interference between companies while using a unified overall system architecture. This segmentation allows cost-effective deployment without cross-company interference.
2Object-affected harmful factors
If separate wireless communication systems are introduced for each company, then communication security is improved, but the introduction cost and system complexity increase
Solution Approach 1:
The patent merges multiple company-specific repeater systems into a single unified wireless communication system. The server unit provides centralized management for all repeaters across different areas, allowing multiple companies to operate securely in their respective areas while sharing common infrastructure. This reduces overall system complexity and introduction costs while maintaining communication security through area-based isolation.
3Object-affected harmful factors
If area-based communication restriction is implemented, then communication security between companies is improved, but management complexity of the system increases
Solution Approach 1:
The patent introduces a server unit as an intermediary that centrally manages all repeaters and area assignments. The server stores area information for each repeater and automatically routes communications based on area identifiers. This centralized mediation simplifies management by providing a single point of control for area-based communication restrictions, rather than requiring complex distributed management across multiple independent systems.

AI summary
[Problem] To provide a voice communication system which causes a relaying device to manage communication between terminal devices based on the affiliations of the terminal devices, and manage the current positions of the respective terminal devices. [Solution] In a voice communication system, a relaying device relays voice communication of a plurality of section systems. The relaying device stores, with respect to each of the section systems, a plurality of pieces of area information divided on the basis of the communication range of a wireless access point. A terminal device transmits a voice signal to which the identification code thereof is added. When receiving the voice signal from the terminal device, the relaying device identifies a section system to which this terminal device belongs from the identification code added to the voice signal, and identifies an area in which the terminal device is present on the basis of positional information relating to the terminal device. The relaying device transfers the voice signal to another terminal device which belongs to the identified section system and is present in the identified area.
