Abstract

A router apparatus is for establishing, in a home network system comprising a plurality of subnetworks including a first subnetwork and a second subnetwork, connection between the respective subnetworks. The router apparatus includes: a first network interface configured to be connected to a first communication device existing on the first subnetwork; a second network interface configured to be connected to a second communication device existing on the second subnetwork; a determination module configured to determine whether a function advertisement notification related to a router device is received from the first communication device; and a providing module configured to provide, to the second communication device, information included in the function advertisement notification received from the first communication device when the determination module determines that the function advertisement notification related to the router device is received.

Claims

1. A router apparatus for establishing, in a home network system comprising a plurality of subnetworks including a first subnetwork and a second subnetwork, connection between the respective subnetworks, the router apparatus comprising:

a first network interface configured to be connected to a first communication device existing on the first subnetwork of a higher level side of the router apparatus;

a second network interface configured to be connected to a second communication device existing on the second subnetwork of a lower level side of the router apparatus;

a determination module configured to determine whether a function advertisement notification related to a router device is received from the first communication device; and

a providing module configured to provide, to the second communication device, information included in the function advertisement notification received from the first communication device when the determination module determines that the function advertisement notification related to the router device is received.

2. The apparatus of claim 1,

wherein the function advertisement notification related to the router device is a function advertisement notification of a UPnP IGD function.

3. The apparatus of claim 1,

wherein the providing module comprises a transfer module configured to transfer the function advertisement notification to the second communication device.

4. The apparatus according claim 1,

wherein the providing module further comprises:

a duplication module configured to duplicate the function advertisement notification; and

a duplication transmission module configured to transmit, to the second communication device, the function advertisement notification duplicated by the duplication module.

5. The apparatus according to claim 1,

wherein the providing module further comprises:

a generation module configured to generate a new function advertisement notification related to the apparatus, the new function advertisement notification being embedded with the information included in the function advertisement notification received from the first communication device; and

an advertisement transmission module configured to transmit, via the second network interface, the new function advertisement notification generated by the generation module.

6. The apparatus according to claim 1,

wherein each of the apparatus and the first communication device comprises:

a setting page transmission module configured to transmit, to other devices, a setting page in which a setting can be made on a given function of the respective present apparatus; and

a function advertisement transmission module configured to transmit, as the function advertisement notification, information including the URL of the setting page to other devices existing at a lower level side of the respective present apparatus,

wherein the second communication device comprises a setting module configured to receive the setting page by accessing the URL of the setting page and to make settings on the router apparatus and the first communication device,

wherein the providing module comprises a setting page generation module configured to paste a link to the URL of the setting page to the function advertisement notification received from the first communication device, thereby generating a setting page of the present apparatus, and

wherein the setting page of the present apparatus is transmitted by the setting page transmission module when access is made to the URL of the setting page by the setting module from the second communication device.
