Abstract

A method, system and terminal for changing an MO of a broadcast service guide. The method for changing an management object (MO) of a broadcast service guide includes: installing an MO tree by a terminal upon receiving a service guide for which at least one management object has been formed from a broadcast server; changing by the terminal a corresponding MO upon receiving a change-requested parameter of the service guide MO from a DM server; and updating by the terminal a corresponding portion of the service guide based on the changed MO. When the subscriber terminal which has received the broadcast service has a problem or needs to be updated, the problem of the terminal can be remotely, quickly and easily solved by correcting the change-requested parameter of the MO of the service guide of the terminal side according to a request of the server or the terminal.

Claims

1. A method for changing a management object (MO) of a broadcast service guide comprising:

a) installing by a terminal an MO tree upon receiving a service guide, for which at least one management object has been formed;

b) changing by the terminal a corresponding MO; and

c) updating by the terminal a corresponding portion of a the service guide based on the changed MO.

2. The method of claim 1, wherein, in the step b), the terminal changes the corresponding MO upon receiving at least one parameter which has been requested to be changed of the service guide MO from a DM server.

3. The method of claim 1, wherein the step b) comprises:

transferring by the terminal a request for changing an MO with a problem of the service guide to a broadcast server; and

changing by the terminal the change-requested MO upon receiving at least one parameter of the change-requested MO from the broadcast server.

4. The method of claim 3, wherein the step, in which the change-requested MO is changed by the terminal which has received the at least one parameter of the change-requested MO from the broadcast server, comprises transferring by the broadcast server the at least one parameter of the MO shared with the DM server.

5. The method of claim 4, wherein, in the step of transferring by the broadcast server the at least one parameter of the MO shared with the DM server, either the broadcast server transfers the at least one parameter of the MO to the terminal, or the DM server transfers the at least one parameter of the MO to the terminal.

6. The method of claim 1, wherein, in the step a), the MO tree is installed by terminal upon receiving a service guide, for which at least one management object has been formed, from the broadcast server.

7. The method of claim 1, wherein, in the step a), a DM client of the terminal installs the MO tree based on the service guide for which at least one management object has been formed.

8. The method of claim 1, wherein, in the step b), the DM client of the terminal changes the change-requested MO.

9. The method of claim 1, wherein the step c) comprises:

updating by the DM client of the terminal a corresponding portion of the service guide.

10. The method of claim 1, wherein the terminal is a previously designated particular terminal.

11. The method of claim 1, wherein after the service guide for which at least one management object has been formed is transferred to the broadcast client from the broadcast server, it is provided in a format that can be recognizable by the DM client.

12. The method of claim 1, wherein the service guide, for which at least one MO has been formed, is transferred to the broadcast client from the broadcast server, and then transferred to the DM client in a format which the DM client is able to recognize.

13. The method of claim 2, wherein the DM server receives a request for changing the MO with respect to a correction portion from the broadcast server.

14. The method of claim 1, wherein, the step a), the DM client of the terminal which has received the service guide MO searches a parameter of the service guide for which at least one management object has been formed, and maps a corresponding parameter to a DM tree.

15. The method of claim 1, wherein the step b) comprises:

receiving by the DM server the parameter information of the change-requested MO from the broadcast server and sharing the same; and

transferring by the DM server a DM command with respect to the changing of the MO to the DM client.

16. The method of claim 1, wherein, in the step b), the DM client which has received the DM command with respect to the changing of the MO from the DM server corrects a corresponding parameter value of the MO tree to a changed parameter value.

17. The method of claim 1, wherein, in the step c), the DM client maps the changed parameter value of the MO tree to a corresponding portion of the service guide.

18. The method of claim 1, wherein, the step b), upon receiving the change-requested MO parameter from the broadcast server, the terminal changes the change-requested MO.

19. The method of claim 3 or claim 18, wherein the terminal is one of multiple non-designated terminals.

20. The method of claim 18, wherein the DM server receives a request for changing the MO with respect to a correction portion from the broadcast server.

21. The method of claim 18, wherein the step b) comprises:

transferring by the broadcast server the parameter information of the change-requested MO to the DM server;

transferring by the broadcast server the at least one parameter of the change-requested MO to the broadcast client;

transferring by the broadcast client the received at least on parameter of the change-requested MO to the DM client; and

correcting by the DM client, which has received a new parameter value of the change-requested MO from the broadcast client, the corresponding parameter value of the DM tree to the new parameter value.

22. The method of claim 3, wherein the changing step is the terminal changes the change-requested MO upon receiving the DM command with respect to the request for changing the MO transferred from the DM server.

23. The method of claim 3, further comprising:

sharing by the broadcast server the MO change request information which has been received from the terminal with the DM server.

24. The method of claim 3, wherein the terminal is a previously designated particular terminal.

25. The method of claim 3, wherein after the service guide, for which at least one management object has been formed, is transferred to the broadcast client from the DM server, it is provided in a format that can be recognizable by the DM client.

26. The method of claim 3, wherein the broadcast client of the terminal transfers the request for changing the MO for which an error has occurred of the service guide to the broadcast server.

27. A system comprising:

a terminal that installs an management object (MO) tree of a service guide and updates a corresponding portion of the service guide based on a changed MO;

a broadcast server that provides a service guide, for which at least one management object has been formed, to the terminal; and

a DM server that receives a request for changing an MO from the broadcast server and transfers a DM command with respect to the change of the MO to the terminal.

28. The system of claim 27, wherein the broadcast server requests a change of the MO to the terminal and delivers at least one parameter of the requested MO to the terminal.

29. The system of claim 27, wherein, if the terminal requests a change of the MO to the broadcast server, the broadcast server delivers at least one parameter of the requested MO to the terminal.

30. A terminal comprising:

a broadcast client that receives a service guide, for which at least one management object has been formed, from a broadcast server; and

a device management (DM) client that installs a management object (MO) tree upon receiving the service guide, for which at least one management object has been formed, from the broadcast client, and changes at least one parameters of a corresponding MO that was requested to be changed.

31. The terminal of claim 30, wherein the DM client receives, from a DM server, a DM command with respect to a change in MO and changes at least one parameter of the corresponding MO.

32. The terminal of claim 30, wherein the DM client receives, from the broadcast server via the broadcast client, a DM command with respect to a change in MO and changes at least one parameter of the corresponding MO.

33. The terminal of claim 30, wherein the broadcast client comprises:

a receiver that receives the service guide, for which at least one management object has been formed, from the broadcast server; and

a transmitter that transmits the received service guide, for which at least one management object has been formed, to the DM client.

34. The terminal of claim 30, wherein the DM client comprises:

a DM enabler that receives the service guide, for which at least one management object has been formed, from the broadcast client to install the DM tree, and

35. The terminal of claim 30, wherein the DM client comprises:
