Abstract

Provided are an apparatus and a method which can transmit an event having occurred in a controlled device to a control device without loss or delay in a web-based system. The apparatus includes an event occurrence detector which detects the occurrence of an event; an event storage unit which stores an occurred event; a response transmitter which transmits a first response including the occurred event to a control device according to a request of the control device; a time measurement unit which measures a time elapsed after the request or the response, and a control unit which transmits a second response to the control device, which selectively asks the control device to re-request a report of an occurred event according to the measured time.

Claims

1. An apparatus for transmitting an event in a web-based system, the apparatus comprising:

an event occurrence detector which detects an occurrence of an event;

an event storage unit which stores the occurred event;

a response transmitter which transmits a first response including the occurred event to a control device according to a request from the control device;

a time measurement unit which measures a time elapsed after the request or the response, and

a control unit which transmits a second response to the control device, which selectively asks the control device to re-request a report of the occurred event according to the measured time.

2. The apparatus of claim 1, wherein, when the control device has received at least one of the first response and the second response, the control device re-requests a report of an occurred event.

3. The apparatus of claim 1, wherein the response transmitter transmits the first response to the control device, the first response comprising at least one event which has been stored in the event storage unit before the control device requests a report of an occurred event.

4. The apparatus of claim 1, wherein the time measurement unit measures the time lapsed after the control device requests the report of an occurred event, and the control unit transmits the second response to the control device, which asks the control device to re-request the occurred event, when no event has occurred during a first time interval after a previous request from the control device is received.

5. The apparatus of claim 1, wherein the time measurement unit measures the time lapsed after the first response or the second response is transmitted to the control device, and the control unit determines that the control device has been disconnected from a network when the control device has not requested a report of the occurred event during a second time interval after the first response or the second response is transmitted to the control device.

6. The apparatus of claim 1, further comprising a management unit which manages transmission of an event to each of one or more control devices which have requested a report of the occurred event.

7. The apparatus of claim 6, wherein the management unit generates a management table for managing transmission of an event to each of the control devices, and the management table comprises a first field for indicating an event that occurred in the controlled device, a second field for indicating a control device which requested report of the occurred event, and a third field for indicating if the occurred event has been transmitted to each control device.

8. An apparatus for receiving an event in a web-based system, the apparatus comprising:

an event request unit which transmits a request for a report of an event that occurred in a controlled device to the controlled device;

a response receiver which receives a first response including the occurred event from the controlled device according to the request; and

a control unit which re-requests the controlled device to report the occurred event after receiving the first response.

9. The apparatus of claim 8, wherein the first response comprises at least one event which occurred before the controlled device receives the request.

10. The apparatus of claim 8, wherein the response receiver receives a second response, which re-requests a report of the occurred event, when no event occurs in the controlled device during a predetermined time interval after the controlled device receives the request.

11. The apparatus of claim 9, wherein the control unit re-requests the controlled device to report an occurred event, after receiving a second response.

12. A method of transmitting an event in a web-based system, the method comprising:

detecting an occurrence of an event;

storing the occurred event;

transmitting a first response including the occurred event to a control device according to a request of the control device;

measuring a time elapsed after the request or the response, and

transmitting a second response to the control device, which selectively asks the control device to re-request a report of the occurred event according to the measured time.

13. The method of claim 12, wherein, when the control device has received at least one of the first response and the second response, the control device re-requests a report of the occurred event.

14. The method of claim 12, wherein, in transmitting the first response, the first response transmitted to the control device comprises at least one event which has been stored before the control device requests a report of the occurred event.

15. The method of claim 12, wherein the measuring of the time comprises measuring the time lapsed after the control device requests report of the occurred event, and the transmitting of the second response comprises transmitting the second response to the control device, which asks the control device to re-request the occurred event, when no event has occurred during a first time interval after a previous request from the control device is received.

16. The method of claim 12, wherein the measuring of the time comprises measuring the time lapsed after the first response or the second response is transmitted to the control device, and the transmitting of the second response comprises determining that the control device has been disconnected from a network when the control device does not request a report of the occurred event during a second time interval after the first response or the second response is transmitted to the control device.

17. The method of claim 12, which further comprises managing transmission of an event to each of one or more control devices which have requested a report of the occurred event.

18. The method of claim 17, wherein the managing of the transmission of an event comprises generating a management table for managing transmission of the occurred event to each of the control devices.

19. The method of claim 18, wherein the management table comprises a first field for indicating the occurred event in the controlled device, a second field for indicating a control device which requested report of the occurred event, and a third field for indicating if the occurred event has been transmitted to each control device.

20. A method of receiving an event in a web-based system, the method comprising:

transmitting a request for a report of an event that occurred in a controlled device to the controlled device;

receiving a first response including the occurred event from the controlled device according to the request; and

re-requesting the controlled device to report the occurred event after receiving the first response.

21. The method of claim 20, wherein the first response comprises at least one event that occurred before the controlled device receives the request.

22. The method of claim 20, wherein the receiving of the first response comprises receiving a second response, which asks a re-request for a report of the occurred event, when no event occurs in the controlled device during a predetermined time interval after the controlled device receives the request.

23. The method of claim 22, wherein the re-requesting of the controlled device to report the occurred event comprises re-requesting the controlled device to report the occurred event, after receiving the second response.
