A data gateway unit includes a configuration information update unit for examining a connection state of a terminal on a customer premise network side, and for updating configuration information on the customer premise network; a service menu unit for enumerating, in response to the configuration information on the customer premise network which the configuration information update unit updates, available services the terminal on the customer premise network side can implement; and a service presentation and selection unit for notifying a user of the available services the service menu unit enumerates, and for accepting a service selected by the user. This can solve a problem of a conventional data gateway unit in that users unfamiliar with a personal computer, home bus, or system information, cannot change the setup of the system easily because of the difficulty to create the system information. |

DETAILED DESCRIPTION The present invention is implemented to solve the foregoing problems.
It is therefore an object of the present invention to provide a data gateway unit and a data gateway method enabling a user to readily identify available services and to easily carry out setup and update of the services.
According to a first aspect of the present invention, there is provided a data gateway unit comprising: configuration information update means for examining a connection state of a terminal on a customer premise network side, and for updating configuration information on the customer premise network; service menu means for enumerating, in response to the configuration information on the customer premise network which the configuration information update means updates, available services the terminal on the customer premise network side can implement; and service presentation and selection means for notifying a user of the available services the service menu means enumerates, and for accepting a service selected by the user.
Here, the service menu means may look at a service table to enumerate the available services the terminal on the customer premise network side can implement.
The service menu means may request a service provider connected to a public network to send update data of the service table, and update the service table in accordance with the update data sent from the service provider.
The service menu means may receive, when a service provider connected to a public network makes an inquiry about an update of the service table, update data of the service table from the service provider, and update the service table in accordance with the update data.
The service menu means may receive, in response to an update request of the service table from a user, update data of the service table from a terminal connected to one of the customer premise network and a public network, and update the service table in accordance with the update data.
The service menu means may further enumerate available services that can be implemented using a function of a terminal connected to a public network
