COMMUNICATION NETWORK SYSTEM, GATEWAY, DATA COMMUNICATION METHOD AND PROGRAM PROVIDING MEDIUM
First Claim
1. A home gateway, comprising:
- an interface unit configured to communicate with two communication networks;
a storage unit configured to store a program data executed at a terminal connected to one of the two communication networks; and
a registration unit configured to register a user identification information or a device identification information in the storage unit,wherein the home gateway requests transmission of an access request and a user identification information or a device identification information, authenticates the user identification information or the device identification information and determines whether or not the user identification information or the device identification information is allowed for receiving the program data.

Abstract
This invention relates to provide a communication network system, a gateway, and a data communication method, in which the gateway has an advanced functionality. A person who issues an access request can retrieve a desired access destination easily by the following configuration: functions of routing information providing and authentication processing are added to a gateway that performs protocol conversion between two different communication networks; when an access request is issued from a public communication network such as Internet to a terminal in a local (private) communication network connected to the gateway, a request terminal is authenticated to enable prevention of unauthorized data writing and reading; and an access request user who succeeded in the authentication is provided with an active terminal list comprising accessible terminal information, or with a user condition table.

2. A home gateway, comprising:
-
an interface unit configured to communicate with private network and public network; a storage unit configured to store a program data executed at a terminal in the private network; and a registration unit configured to register a device identification information in the storage unit, wherein the home gateway requests transmission of an access request and a device identification information, authenticates the device identification information received from the terminal in the private network to determine whether or not the program data stored in the storage unit is allowed to use by the terminal.

3. A home gateway, comprising:
-
interface means for communicating with first protocol network and second protocol network; storage means for storing a program data executed at a terminal in the first protocol network; registration means for registering a device identification information in the storage means; receiving means for receiving from the terminal an access request and a device identification of the terminal; authentication means for authenticating the terminal with the device identification received by the receiving means by using the registration means; and conversion means for conversion the program data for execution at the terminal for transmission to the terminal if the authentication means determines the terminal device is authenticated.

4. A communication device, comprising:
-
interface means for communicating with two different protocol network; storage means for storing a program data executed at a terminal in the one of the two different protocol network; registration means for registering a device identification information in the storage means; receiving means for receiving from the terminal an access request and a device identification of the terminal; authentication means for authenticating the terminal with the device identification received by the receiving means by using the registration means; and conversion means for conversion the program data for execution at the terminal for transmission to the terminal from one of the two different protocol network to the other of the two different protocol network if the authentication means determines the terminal device is authenticated.
