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 in a broadcast service by applying a device management (DM) technique based on a two-way communication, the method comprising:

installing, by a terminal, a MO tree of a hierarchy structure using a service guide MO defined by a device management (DM) server upon receiving the service guide MO transmitted by a broadcast server on behalf of the DM server, wherein the service guide MO has been formed as a format of MO for the service guide MO such that the service guide MO is composed of one or more parameters, and includes at least one management object (MO) associated with the broadcast service guide;

directly transferring, by the terminal to the broadcast server, a request to change the service guide MO, wherein the transferred request allows the broadcast server to communicate with the DM server in order to obtain from the DM server information on the one or more parameters to be changed or updated in the service guide MO and transfer the changed or updated one or more parameters to one or more terminals, including the terminal, on behalf of the DM server;

receiving, by the terminal, the changed or updated one or more parameters of the service guide MO transferred from the broadcast server on behalf of the DM server or directly from the DM server in response to the request to change the service guide MO,

wherein if the terminal is the only receiver that is intended to receive the changed or updated one or more parameters, the changed or updated one or more parameters are transferred to the terminal in a point-to-point manner by the DM server, and

if the terminal is not the only receiver that is intended to receive the changed or updated one or more parameters, the changed or updated one or more parameters are transferred to the terminal in a point-to-multipoint manner by the broadcast server; and

updating, by the terminal, a corresponding portion of the service guide MO based on the received change-requested MO parameter using one of the Get, Add and Replace commands.

2. The method of claim 1, wherein the updating further comprises:

transferring, by a broadcast client of the terminal, the changed or updated one or more parameters to a DM client of the terminal; and

updating, by the DM client of the terminal, the service guide MO by changing a corresponding parameter value of the installed MO tree to a value of the changed or updated one or more parameters and mapping a value of the changed or updated one or more parameters of the MO tree to a corresponding portion of the service guide MO.

3. The method of claim 1, wherein the installing comprises:

receiving, by a broadcast client of the terminal, the service guide MO from the broadcast server;

transmitting, by the broadcast client of the terminal, the service guide MO to a DM client of the terminal; and

installing, by the DM client of the terminal, the MO tree using the service guide MO.

4. A terminal of receiving a broadcast service applying device management (DM) technique based on two-way communication to change a management object (MO) of a broadcast service guide, the terminal comprising:

a processor configured to act as

a broadcast client that receives a service guide management object (MO) defined by a device management (DM) server, for which at least one management object has been formed, transmitted by a broadcast server on behalf of the DM server, directly transfers a request to change the service guide MO to the broadcast server, wherein the transferred request allows the broadcast server to communicate with the DM server in order to obtain from the DM server information on the one or more parameters to be changed or updated in the service guide MO and transfer the changed or updated one or more parameters to one or more terminals including the terminal on behalf of the DM server, and receives the changed or updated one or more parameters of the service guide MO transferred from the broadcast server on behalf of the DM server or directly from the DM server in response to the request to change the service guide MO, and

a device management (DM) client that installs a management object (MO) tree upon receiving the service guide MO from the broadcast client, and updates at least one parameters of a corresponding MO in the service guide MO based on the changed or updated one or more parameters using one of DM commands including Get, Add and Replace commands which are specified in the service guide MO,

wherein if the terminal is the only receiver that is intended to receive the changed or updated one or more parameters, the changed or updated one or more parameters of the service guide MO, in response to the request to change the service guide MO, are received from the broadcast server by the broadcast client, and

if the terminal is not the only receiver that is intended to receive the changed or updated one or more parameters, the changed or updated one or more parameters of the service guide MO, in response to the request to change the service guide MO, are received from a device management (DM) server by the DM client.

5. A method for changing a management object (MO) of a broadcast service guide in a point-to-multipoint broadcast service by applying a device management (DM) technique based on a two-way communication, the method comprising:

transferring, by a broadcast server, a service guide MO defined by a device management (DM) server on behalf of the DM server to a terminal in order to be installed in the terminal;

receiving, by the broadcast server, a request to change or update the service guide MO from the terminal;

communicating, by the broadcast server, with the DM server in order to obtain from the DM server information on parameters to be changed or updated in the service guide MO and transfer the changed or updated parameters to one or more terminals, including the terminal, on behalf of the DM server according to the request to change or update the service guide MO; and

transferring, by the broadcast server on behalf of the DM server, the changed or updated parameters of the service guide MO to one or more terminals including the terminal if the terminal is not the only receiver that is intended to receive the changed or updated parameters, in order to change or update, by the terminal, a portion of the service guide MO corresponding to the request to change or update the service guide MO using one of DM commands including Get, Add and Replace commands which are specified in the service guide MO.

6. The method of claim 5, wherein the service guide MO has been formed by the broadcast server as a format of MO for the service guide such that the service guide MO is composed of one or more parameters, and includes at least one management object associated with a broadcasting service guide.

7. The method of claim 5, wherein the terminal includes a broadcast client and a device management (DM) client, wherein the broadcast client of the terminal receives the service guide MO from the broadcast server and transfers the received service guide MO to the DM client of the terminal, and the DM client of the terminal installs a MO tree using the service guide MO.

8. The method of claim 7, wherein the service guide MO is provided by the broadcast client of the terminal, in a format that can be recognized by the DM client of the terminal.

9. A method for changing a management object (MO) of a broadcast service guide, in a broadcast service by applying a device management (DM) technique based on a two-way communication, the method comprising:

transferring, by a broadcast server on behalf of a device management (DM) server, a service guide MO defined by the DM server to a broadcast client of a terminal in order to be installed in a DM client of the terminal;

receiving, by the broadcast server, a request to change or update the service guide MO from the broadcast client of the terminal; and

communicating, by the broadcast server, with the DM server in order to share information on parameters to be changed or updated in the service guide MO according to the request to change or update the service guide MO, such that the DM server transfers to the DM client of the terminal or each DM client of other terminals, the changed or updated parameters of the service guide MO if the terminal is the only receiver that is intended to receive the changed or updated parameters in order for the DM client of the terminal to change or update a portion of the service guide MO corresponding to the request to change or update the service guide MO using one of DM commands including Get, Add and Replace commands which are specified in the service guide MO.
