WIPO Patent Application WO/2015/133044
Kind Code:
A1
Abstract:
[Problem] To provide a voice communication system which causes a relay 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 relay device relays voice communication of a plurality of section systems. The relay 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 relay 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 relay device transfers the voice signal to another terminal device which belongs to the identified section system and is present in the identified area.
