Abstract

Disclosed are a service gateway system and a method of using the same. The service gateway system includes a client agent and a service proxy. The client agent is capable of communicating with an external network, receives information on new services provided by service providers through the external network, updates a service bundle catalogue reflecting the received information, and shows the updated service bundle catalogue. The service proxy pushes an alarm message on the update of the service bundle catalogue and the updated service bundle catalogue to a registered home appliance so that a user may select the service for use through the home appliance. According to the above configuration, the user becomes aware of the arrival of the new service bundle in real time and selectively requests the new services for use.

Claims

1. A service gateway system comprising:

a client agent communicating with an external network, the client agent receiving information on at least one of new services provided by service providers through the external network, updating a catalogue of available services reflecting the information, in an update, and showing an updated catalogue; and

a service proxy sending a message about the update of the catalogue and the updated catalogue to a device.

2. The service gateway system of claim 1, wherein the catalog is a service bundle catalog and a service bundle is generated by a remote server connected to the external network and is delivered in an Open Service Gateway initiative (OSGi)-compliant form.

3. The service gateway system of claim 1, wherein the device receives the updated catalogue and transmits a response signal to the service proxy, and the service proxy delivers the response signal to the client agent to request a use of at least one of the new services to the remote server.

4. The service gateway system of claim 3, wherein the device comprises a display device and the message is displayed on the display device through a pop-up window.

5. The service gateway system of claim 4, wherein the service proxy uses a push technology for pushing the message and the updated catalogue in a sequence.

6. The service gateway system of claim 5, wherein the service proxy comprises:

an update checking unit for examining whether the catalogue is updated or not;

a registration authenticating unit for registering and authenticating the device;

a message processing unit for transmitting the response signal from the device to the client agent;

a JAVA code processing unit for generating and transmitting JAVA bytecodes to the device, the JAVA bytecodes enabling a download of the information through the push technology; and

a push server unit for pushing the information to the device through the push technology.

13. The service gateway system of claim 1, wherein the device is a home appliance.

14. The service gateway system of claim 1, wherein the message is an alarm message.

15. The service gateway system of claim 1, wherein the service proxy pushes the message and the updated catalogue.

16. The service gateway system of claim 1, wherein a user selects one of the at least one of the new services from the updated catalogue through the device.

7. A method of using a service gateway system comprising:

(a) receiving information on at least one of new services provided by service providers from a remote server connected to an external network;

(b) updating a catalogue of available services reflecting the information and showing an updated catalogue; and

(c) registering a device having a display device and delivering a message on an update of a service bundle and the catalogue to the device.

8. The method of claim 7, wherein, in receiving the information, the service bundle is transmitted in an Open Services Gateway initiative (OSGi)-compliant form.

9. The method of claim 7, further comprising:

receiving a response signal of requesting a use of the at least one of the new services from the device; and

sending the response signal to the remote server and requesting the at least one of the new services.

10. The method of claim 9, wherein, in delivering the message, the message is displayed on the display device of the device through a pop-up window.

11. The method of claim 10, wherein, in delivering the message, the message and the updated catalogue are sequentially delivered to the device by means of a push technology.

12. The method of claim 11, wherein delivering the message comprises:

generating JAVA bytecodes for receiving the information by means of the push technology; and

transmitting the JAVA bytecodes to the device.

17. The method of claim 7, wherein the device is a home appliance.

18. The method of claim 7, wherein the message is an alarm message.

19. The method of claim 7 further comprising selecting one of the at least one of the new services through the device.
