Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, an apparatus and method for providing provisioning information in a CMB system will be described.

1 is a diagram showing the structure of a CBMS according to the present invention.

Referring to FIG. 1, IP datacasting in a digital video broadcasting-handheld (DVB-H) system includes a plurality of entities required for operation. These entities are as follows:

The content generation unit 110 generates content and provides it to the service application unit 120. The service application unit 120 collects content from various sources and metadata associated with the source to provide a service application.

The service manager 110 is composed of several sub-entities for each management of a service, which will be described below.

The bearer (service application) is transmitted to the terminal 160 through the broadcast network 140 and the interactive network 145.

In the CBMS, the terminal 160 may receive service and signaling on the broadcast network. Then, bidirectional communication is performed on the interactive network. That is, the signaling information transmitted by the terminal 160 is provided to the service application unit 120 through the interactive network 145.

Here, CBMS-x and X-x are reference points among other functional entities. And, CBMS-x is a reference point in the scope of IP data cast according to the DVB-H standard. And X-x represents a reference point in the scope of the IP data cast outside the DVB-H standard.

Provisioning information basically includes information on information of a broadcast provider for receiving a broadcast by a terminal. There are two types of home and roaming as follows. First, the parameter in the case of the groove is as follows.

1.Home IPDCOperator (identified by IPDCKMSId / IPDCOperatorId)

2.Home IP platform (identified by Platform_id)

3.Home ESG Provider (identified by ProviderURI)

4.Home ESG (identified by ESGURI)

5.Home network (identified by network_id, MCC, MNC)

6.Home region information (identified by network_id / cell_id, MCC / MNC / cell_id, GPS)

7.Home tuning information (e.g. Frequency)

 The parameters corresponding to roaming are as follows.

1.Roaming IPDCOperator (identified by IPDCKMSId / IPDCOperatorId)

2.Roaming IP platform (identified by Platform_id)

Roaming ESG Provider (identified by ProviderURI)

Roaming ESG (identified by ESGURI)

5.Roaming network (identified by network_id, MCC, MNC)

6.Roaming region information (identified by network_id / cell_id, MCC / MNC / cell_id, GPS)

7.Roaming tuning information (e.g. frequency)

In addition, Table 1 below shows parameters currently supported in provisioning information.

Possible way for provisioning Parameter Manufacture IPDC MO ESG bootstrap HomeIPDCOperator x x x HomeIPPlatform x x HomeESGProvider x x x HomeESG x x x Homenetwork x x HomeRegionInformation x HomeTuningInformation x RoamingIPDCOperator x x RoamingIPPlatform x RoamingESGProvider x RoamingESG x x RoamingNetwork x RoamingRegionInformation x RoamingTuningInformation x Cleartoairservice x

Referring to Table 1, parameters of all terminals are not provisioned in a manufacturing step. This is because if the parameter is provisioned in the manufacturing step, it is very difficult to change it later. Therefore, only static parameters can be provisioned at this stage.

Among the above parameters, HomeIPPlatform, HomeESGProvider, HomeESG, and Homenetworok are not retained forever, so it is not appropriate to be provisioned at the manufacturing stage.

In order to obtain information on the IPDC MO, the UE must support the OMA DM. However, this is optional and not all terminals support it.

And even if the terminal supports the OMA DM, such information must be obtained through the interactive network. However, since such information is useful information for all terminals, it is more appropriate to broadcast such information in a service than through the interactive network.

The RoamingInformationDescritptor parameter is provided as a roaming parameter in the ESG Bootstrap phase. But this is also optional. This information is only available after the IP platform has been selected and the associated ESG Bootstrap information has been parsed. Therefore, there is still no IP platform provisioning information in the current state.

Therefore, it is necessary to broadcast such provisioning information listed in Table 1 above. To this end, several methods for signaling such provisioning information are proposed.

The syntax, which is a method of configuring such provisioning information, is shown in Table 2 below.

The present invention proposes four methods for signaling such provisioning information.

First, the first method will be described below.

Provisioning information is signaled separately in bootstrap information. In other words, an entry point for the provisioning information is signaled to the terminal.

2 is a diagram illustrating a first method for signaling provisioning information according to an embodiment of the present invention.

Referring to FIG. 2, an entry point may be included in PSI / SI information and signaled. The entry point may be a fixed and fixed IP address for provisioning information in the IP platform. The entry point may be a port number, a TSI, a URL, etc., in addition to the IP address.

In Table 6 below, target_provisioning_descriptor is a new descriptor indicating an entry point for signaling the provisioning information.

IP / MAC_notification_section { target _ provisioning _ descriptor () => Fixed entry point for the ProvisioningInformation }

When the terminal receives the PSI / SI and analyzes the PSI / SI, an IP address of an entry point for provisioning information may be obtained. The terminal accesses such provisioning information to determine which IP platform, ESG provider, and which ESG are appropriate. Thereafter, the terminal performs an access process after the selection process.

Now, the second method will be described.

3 is a diagram illustrating a second method for signaling provisioning information according to an embodiment of the present invention. The second method is to add a descriptor or table containing provisioning information in the PSI / SI.

The provisioning information may take the form of NIT, INT, SDT and any other table in the PSI / SI and may be added as a new descriptor. The new descriptor added is shown in Table 7 below.

ProvisioningInformation Descriptor {Version_no Descriptor_tag n_o_Operators for (i = 0; i <n_o_Operators; i ++) {Operator_Index [i] IPDC_Operator_ID [i] KMS_ID [i]} n_o_local_Operators_with_signaled_Roaming_Partners for (i = 0; i <n_o_local_Operators_with_signaled_Roaming_Partners; i ++) {local_Operator_with_signaled_Roaming_Partners_Index [i] N_o_Roaming_Partners_signaled [i] for (k = 0; k <n_o_Roaming_Partners_signaled [i]; k ++) {Signaled_Roaming_Partner_Index [i] [k]}} n_o_Platform_IDs for (j = 0; n_o_Platform_IDsID jj) for (i = 0; i <n_o_ESG_IDs; i ++) {ESG_ID [i] clear-to-air_services_available [i] N_o_local_Operators_on_ESG [i] for (k = 0; k <n_o_local_Operators_on_ESG [i]; k ++) {local_OperatorIndexion k]}}}}

The meaning of the descriptor described in Table 7 is as described above.

In the second method as described above, when the terminal receives the PSI / SI, the terminal may acquire the provisioning information. Based on this, the terminal can determine the IP platform, ESG provider, ESG to access.

Now, a third method will be described.

4 illustrates a third method for signaling provisioning information according to an embodiment of the present invention.

Referring to FIG. 4, in addition to the general DVB-H signal, provisioning information may be independently assigned a fixed frequency band and transmitted through this band. Based on this, the terminal can always check the fixed frequency band to obtain the provisioning information and access the service based on the provisioning information.

Now, a fourth method will be described.

When a specific entry point is allocated for provisioning information, the terminal may request the specific entry point through an interactive network.

The entry point may be included in PSI / SI, ESG bootstrap or notification and signaled to the terminal.

5 is a flowchart illustrating a process of obtaining provisioning information in a terminal according to an embodiment of the present invention.

Referring to FIG. 5, when the aforementioned method 1 is used, the terminal receives PSI / SI information and obtains an entry point. In operation 510, the terminal retrieves provisioning information from the entry point.

Thereafter, the terminal acquires the provisioning information after the search process (step 520). Thereafter, the terminal can select the correct IP platform to bootstrap, and can select the correct ESG to connect.

When the aforementioned method 2 is used, the terminal receives PSI / SI information and obtains provisioning information from a descriptor or a table from the PSI / SI information (step 530). Thereafter, the terminal can select the correct IP platform to bootstrap, and can select the correct ESG to connect.

When the aforementioned method 3 is used, the terminal may acquire provisioning information using a fixed frequency band (step 540). Thereafter, the terminal may select and access a general signal (frequency band) for receiving an application service of the system based on the provisioning information (step 550).

If the aforementioned method 4 is used, the terminal receives an entry point determined to obtain provisioning information (step 560). The determined entry point may be obtained through a method such as PSI / SI, ESG bootstrap, notification message, or the like.

The terminal acquires provisioning information through the entry point (step 570). Thereafter, the terminal can select the correct IP platform to bootstrap, and can select the correct ESG to connect.

The algorithm for the present invention is then terminated.

6 is a flowchart illustrating a process of providing provisioning information in a server according to an exemplary embodiment of the present invention.

Referring to FIG. 6, when the aforementioned method 1 is used, the server signals the terminal by including an address of an entry point for provisioning information in the PSI / SI information (step 610).

When the above-described method 2 is used, the server signals the terminal by including a descriptor or table for provisioning information in the PSI / SI information (step 620).

When the above-described method 3 is used, the server includes provisioning information in a fixed frequency band and signals to the terminal (step 630).

When the aforementioned method 4 is used, the server signals the determined entry point to the terminal (step 640). Thereafter, when receiving a request message from the terminal, the provisioning information is transmitted to the terminal (step 650).

The algorithm for the present invention is then terminated.

7 is a block diagram of a server according to an embodiment of the present invention.

Referring to FIG. 7, the service application unit 710 collects content and metadata about the same from various sources in order to provide a service.

In addition, the service application unit 710 performs a service protection function. The service application unit 710 may exist for each application provided in the IP datacast.

The service manager 720 includes a service guide provisioning application 722, a service setting and allocating unit 724, a security / service protection provisioning unit 726, and a location service unit 728.

The service guide provisioning application unit 722 is responsible for recruiting the ESG which is metadata information from the service application.

The service setting and allocating unit 724 is responsible for registering a service application for requesting bandwidth of a broadcast. For example, it is responsible for registration of one DVB-H IP platform in one DVB transport stream. It is responsible for allocating services according to places, allocating bandwidth according to time, and allocating service schedules. It is responsible for managing sub-entities associated with broadcast bandwidth contention.

The security / service protection provision unit 726 is responsible for the user's access to the service application.

The location service unit 728 provides a location service including interaction bearer network functionality or a GPS service to the service application.

The service application is transmitted via broadcast network 730.
