An Internet terminal comprising: a communication unit that sends a local packet generated by a packet generation unit and receives a response local packet from a server apparatus; an encryption processing unit that encrypts the local packet to be sent out and decrypts the received response local packet; the packet generation unit that generates the local packet; a polling information storage unit that holds a terminal ID and a password used for identifying the internet terminal; a polling interval adjustment unit that identifies a polling interval at which the local packet is periodically sent to the router; and a control unit that sends control information to a terminal apparatus to be controlled and controls such terminal apparatus accordingly.

Home terminal apparatus and communication system

An internet terminal, which includes a communication unit for sending and receiving packet data, an encryption unit for encrypting and decrypting packet data, a packet generation unit for generating packet data to be sent to a server apparatus, a protocol determination unit for determining a communication protocol to be used between the internet terminal and the server apparatus, a control request reading unit for reading in packet data and a control request packet that includes a control request, a control unit for receiving control information and controlling the internet terminal or a terminal apparatus accordingly. Further, the internet terminal includes a server certificate authentication unit for authenticating the validity of a server certificate sent by the server apparatus, a client certificate management unit for sending a client certificate to the server apparatus, and a storage unit for storing a terminal ID and other information.

Apparatus, method and computer software products for controlling a home terminal

The communication system according to the present invention is made up of: a connected communication terminal () to which communication is requested; a connecting communication terminal () that requests a communication with the connected communication terminal (); a session management server () that manages sessions between the communication terminals; a trigger server () that transmits, to the connected communication server (), the request made by the session management server (); and routers (and) that relay between the connecting communication terminal () and the connected communication terminal (), and a network (). In the system, the connected communication terminal () holds a permission list (L) that is a list of communication terminals to which connection is permitted, and the session management server () judges, with reference to the permission list (L), whether or not the communication between the connected communication terminal () and the connecting communication terminal () is permitted.
