Abstract

The present invention relates to method and apparatus for enabling remote query and control for a device on a home network. A starting control point or a gateway of home network in accordance with the present invention makes out a document of device list that shows a device in association with location information of a presentation page written in a device descriptor received from at least one of devices connected to a home network; and provides the document for a general browser to interpret/process in order that device list of the home network is displayed by the general browser when the general browser is executed.

Claims

1. A method for making at least one of a plurality of devices on a local network remotely-accessible, comprising the steps of:

(a) extracting information for presentation from a device description provided by each of the plurality of devices; and

(b) creating a document listing devices each of which is associated with the extracted information for presentation, the document being written in a language that can be interpreted by a browser.

2. The method of claim 1, further comprising the step of:

(c) invoking the browser and making the browser interpret/process the created document.

3. The method of claim 1, further comprising the step of:

(c) providing the created document for the browser when the browser makes a request for connection.

4. The method of claim 1, wherein the browser is a web browser or a WAP browser.

5. The method of claim 1, wherein the step (b) writes the document listing devices in a markup language.

6. The method of claim 1, further comprising the step of:

(c) requesting a presentation page corresponding to an item which a user selects from a screen output displayed through the browser'"'"'s interpretation and processing of the created document, and interpreting, processing, and displaying the presentation page received according to the requesting.

7. The method of claim 6, wherein the presentation page designates actions for query and/or control for a corresponding device in a markup language.

8. The method of claim 7, further comprising the step of:

(d) invoking an action to one of the plurality of devices, the action being corresponding to an item which a user selects from the presentation page displayed by the step (c).

9. The method of claim 1, wherein the plurality of devices are devices which responded to a search message which had been sent to the local network prior to the step (a).

10. The method of claim 1, wherein the information for presentation is a URL.

11. An apparatus for accessing at least one of a plurality of devices on a local network through a global network, comprising a device which can communicate with the local network by connecting to the global network, the device including:

a browser for interpreting and processing a document written in a markup language; and

a starting application for creating a document listing devices each of which is associated with information for presentation contained in each device description received from at least one of the plurality of devices through the global network, and invoking the browser to interpret and process the created document.

12. The apparatus of claim 11, wherein the browser is a web browser or a WAP browser.

13. The apparatus of claim 11, wherein the browser further displays a page for selecting devices by interpreting and processing the created document, requests a presentation page corresponding to a device selected by a user, and interprets, processes, and displays the presentation page received according to the requesting.

14. The apparatus of claim 13, wherein the presentation page designates actions for query and/or control for the corresponding device in a markup language.

15. The apparatus of claim 14, wherein the browser further invokes an action to one of the plurality of devices, the action being corresponding to an item which a user selects from a screen output generated from interpretation of the presentation page.

16. The apparatus of claim 11, wherein the starting application receives the device description by making a request for the device description to at least one of the plurality of devices which responded to a search message which had been sent to the local network.

17. An apparatus for making at least one of a plurality of devices on a local network accessible from a remote site, comprising:

a gate device for sending a search message to the local network, for creating a document listing devices each of which is associated with information for presentation contained in each device description sent by at least one of the plurality of devices responsive to the search message, and for providing the created document for a browser when the browser makes a request for a connection from the remote site.

18. The apparatus of claim 17, wherein the browser is a web browser or a WAP browser.

19. The apparatus of claim 17, wherein the gate device receives the device description by making a request for the device description to at least one of the plurality of devices which responded to the search message.

20. The apparatus of claim 17, wherein the gate device creates a plurality of documents listing devices based on preset user access right information and provides one of the created plurality of documents when the browser makes the request for a connection, depending on a user of the browser.

21. The apparatus of claim 20, wherein at least two of the created plurality of documents have different lists of devices.
