COMMUNICATION DEVICE, COMMUNICATION SYSTEM, COMMUNICATION METHOD AND COMPUTER PROGRAM PRODUCT

摘要

According to an embodiment, a communication device includes a connection establishment unit, a forwarder, and a generator. The connection establishment unit is configured to receive, from a terminal device, a connection request containing identification information of the terminal device, establish a communication connection with the terminal device, and store the identification information and terminal connection information. The forwarder is configured to receive, from a first terminal device, a message to be transmitted from the first terminal device to a second terminal device, and forward the message to the second terminal device, based on forwarding information containing the terminal connection information corresponding to the identification information of the first terminal device, and the terminal connection information corresponding to the identification information of the second terminal device. The generator is configured to generate the forwarding information, based on a request from the forwarder or the connection establishment unit.

主权项

1. A communication device that communicates with a terminal device via a network, the device comprising:
a connection establishment unit configured to
receive, from the terminal device, a connection establishment request containing at least terminal identification information of the terminal device,establish a communication connection with the terminal device, andstore the terminal identification information contained in the connection establishment request and terminal connection information indicating the communication connection established with the terminal device so that the terminal identification information and the terminal connection information are associated with each other; a forwarder configured to
receive, from a first terminal device, a message to be transmitted from the first terminal device to a second terminal device, andforward the message containing forwarding information to the second terminal device, based on the forwarding information containing the terminal connection information corresponding to the terminal identification information of the first terminal device, and the terminal connection information corresponding to the terminal identification information of the second terminal device; and a forwarding information generator configured to generate the forwarding information, based on a request from the forwarder or the connection establishment unit.
