Abstract

This invention provides a system and method to use continuously the same Internet services using different digital terminals even though user moves to another places. A system for providing Internet service using heterogeneous digital terminals includes a terminal registration/unregistration unit for registering and unregistering information on the digital terminals in and from an Internet service provider (ISP) server, a service management protocol unit for requesting the service from the ISP server, a terminal selection/change unit for selecting one of the registered digital terminals to use the service and reporting the selection to the ISP server, a content transmission/reception unit for receiving content service corresponding to the service request from the ISP server via the selected digital terminal, and a continuous-service preparation unit for preparing use of the service using a changed digital terminal.

Claims

1. A system for providing Internet service using heterogeneous digital terminals, the system comprising:

a terminal registration/unregistration unit for registering and unregistering information of the digital terminals in and from an Internet service provider (ISP) server;

a service management protocol unit for sending a service request for a service to the ISP server;

a terminal selection/change unit for selecting one of the registered digital terminals to use the service using the selected terminal, and reporting the selection to the ISP server;

a content transmission/reception unit for receiving content service, corresponding to the service request, from the ISP server; and

a continuous-service preparation unit for preparing the service to a changed digital terminal.

2. The system of claim 1, wherein the ISP server comprises:

a subscriber management unit for storing information of the digital terminals;

a content management unit for searching for the requested service to register the service for each subscriber and storing information of the selected digital terminal selected by the subscriber;

a content transmission/reception unit for sending content service to the selected digital terminal when the selected digital terminal is normal;

a subscriber-specific terminal management unit for, when a request for a terminal change is received from the selected digital terminal while the content service is being sent, continuously sending the content service to the changed digital terminal; and

a terminal-specific content conversion unit for converting the content to be suitable for the selected digital terminal when the selected digital terminal is abnormal.

3. The system of claim 2, wherein, when the request for the terminal change is not received from the selected digital terminal while the content service is being sent, the subscriber-specific terminal management unit continuously sends the content service to the selected digital terminal until a request for service termination is received.

4. The system of claim 1, wherein when a request for a terminal change is received, the terminal selection/change unit changes the selected terminal to another terminal of the registered digital terminals to use the service using said another terminal and reports the change to the ISP server.

5. The system of claim 1, wherein the content transmission/reception unit continuously receives the content service from the ISP server only in a continuous-service mode.

6. A method for providing Internet service using heterogeneous terminals, the method comprising:

registering information of digital terminals in an ISP server;

requesting a service to the ISP server, selecting one of the registered digital terminals to use the service using the selected digital terminal, and reporting the selection to the ISP server;

receiving a content service, corresponding to the requested service, from the ISP server using the selected digital terminal;

when a request for a terminal change is received, changing the terminal to another terminal of the registered digital terminals to use the service using said another terminal and sending a request to a terminal change to the ISP server.

7. The method of claim 6, further comprising:

storing information of the digital terminals;

searching for the requested service and registering the same for each subscriber;

storing information of the selected digital terminal selected by the subscriber;

when the selected digital terminal is normal, sending the content service to the selected digital terminal; and

when the request for the terminal change is received from the digital terminal while the content service is being sent, continuously sending the content service to said another digital terminal.

8. The method of claim 7, further comprising, when the request for the terminal change is not received from the digital terminal while the content service is being sent, continuously transmitting the content service to the selected digital terminal until service termination is requested.

9. The method of claim 7, further comprising, when the selected digital terminal is abnormal, converting the content to be suitable for the selected digital terminal and sending the converted content service to the selected digital terminal.

10. The method of claim 6, further comprising, continuously receiving the content service from the ISP server using said another digital terminal only in a continuous-service mode.
