Title:
NETWORK COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/035208
Kind Code:
A1
Abstract:
The present invention performs connections only to trusted terminal devices, while alleviating a load in connection mediation processing. An address table (TG) stored inside a connection mediation device (100G) stores group information (X, Y) in which a terminal ID and a location address are associated for each terminal device (200A-200D) and which indicates a group to which each terminal belongs. When starting communications with a communication destination terminal (200B), a communication origin terminal (200A) makes a connection mediation request to the connection mediation device (100G). The connection mediation device (100G) references the group information, performs connection mediation if the connection origin terminal ID (0010) and the connection destination terminal ID (0020) are in the same group, and returns the location address (AD2) of the communication destination terminal (200B) to the communication origin terminal (200A). The connection origin terminal (200A) makes a communication start request directed to the returned location address (AD2) and establishes a communication session.
