Communication system, relay device, and information processing device
First Claim
1. A communication system comprising:
- a relay device configured to control communication of a first network;
one or more first terminals connected to the first network;
a second terminal, amongst the one or more first terminals, connectable to the first network and connectable to a second network; and
a third terminal connectable to the second terminal through the second network,the relay device including;
a storage unit configured to store terminal specification information for specifying the third terminal associated with the second terminal;
a transmission unit configured to transmit relay-device specification information for specifying the relay device and terminal authentication information of the third terminal to the second terminal through the first network;
an authentication control unit configured to authenticate the terminal authentication information received from the third terminal through the second network; and
a first communication control unit configured to connect the third terminal to the first network if the authentication control unit authenticates the terminal authentication information,the second terminal including a second communication control unit configured to transmit the relay-device specification information and the terminal authentication information to the third terminal through the second network if receiving the relay-device specification information and the terminal authentication information from the relay device,the third terminal including a third communication control unit configured to transmit the terminal authentication information to the relay device specified by the relay-device specification information through the second network.

Abstract
A communication system includes: a relay device including: a storage unit configured to store terminal specification information for specifying the third terminal associated with the second terminal, and a first communication control unit configured to connect the third terminal to the first network if an authentication control unit authenticates the terminal authentication information; one or more first terminals connected to a first network; a second terminal connectable to the first network and including a second communication control unit configured to transmit the relay-device specification information and the terminal authentication information to the third terminal through the second network if receiving the relay-device specification information and the terminal authentication information from the relay device; and a third terminal connectable to a second network and including a third communication control unit configured to transmit the terminal authentication information to the relay device through the second network.

8. A relay device configured to control communication of a first network to which each of one or more first terminals and a second terminal amongst the one or more first terminals is connectable, and communication on a second network through which the second terminal is connectable to a third terminal, the relay device comprising:
-
a storage unit configured to store terminal specification information for specifying the third terminal associated with the second terminal; a transmission unit configured to transmit relay-device specification information for specifying the relay device and terminal authentication information of the third terminal to the second terminal through the first network; an authentication control unit configured to authenticate the terminal authentication information if receiving the terminal authentication information transmitted to the third terminal through the second network by the second terminal, from the third terminal through the second network; and a first communication control unit configured to connect the third terminal to the first network if the authentication control unit authenticates the terminal authentication information. - View Dependent Claims (9, 10, 11, 12)

13. An information processing device connectable to a relay device configured to control communication of a first network to which each of one or more internal terminals including the information processing device is connected and control, through the first network, communication of a second network to which each of an external terminal and the information processing device is connectable,
the information processing device comprising: -
a first transmission unit configured to, if receiving relay-device specification information for specifying the relay device and terminal authentication information of the external terminal from the relay device through the first network, transmit the relay-device specification information and the terminal authentication information to the external terminal through the second network; a second transmission unit configured to transmit the terminal authentication information to the relay device through the first network if receiving the terminal authentication information transmitted by the first transmission unit, from the external terminal through the second network; and a determining unit configured to determine whether the information processing device is simultaneously connectable to the first network and to the second network if receiving the relay-device specification information and the terminal authentication information from the relay device, the first transmission unit being configured to; transmit communication scheme information indicating an indirect scheme of connecting the relay device and the external terminal through the information processing device, along with the relay-device specification information and the terminal authentication information to the external terminal if the determining unit determines that the information processing device is simultaneously connectable to the first network and to the second network; and transmit communication scheme information indicating a direct scheme of connecting the relay device and the external terminal without using the information processing device, along with the relay-device specification information and the terminal authentication information to the external terminal if the determining unit determines that the information processing device is not simultaneously connectable to the first network and to the second network. - View Dependent Claims (14, 15, 16)
