It can be implemented by further adding the server interface module 114 and the account management module 115 to any one of the devices.

Hereinafter, referring to the message flow charts shown in FIGS. 6 to 18, based on the content providing system of the present invention described above, a content providing method for home electronic devices connected to a home network (hereinafter, referred to as content providing method) will be described. Explain. In the present embodiment, only the indoor electronic device 120 is described as an example. However, all the procedures described below may be applied to all indoor electronic devices 120 to 170 provided in the home network system 100.

6 is a message flow diagram illustrating a registration procedure of the home server 110 in the content providing method according to the present invention.

Referring to FIG. 6, when power is applied (S61), the home server 110 first transmits a registration request message (VNAS_REG_REQ) to the registration server 230 of the content providing system 200 (S62). The registration request message includes identification information (hereinafter, referred to as home server ID) for identifying the home server 110 along with address information (hereinafter, referred to as first address information) set in the home server 110. do. The first address information may include a port number assigned to the home server 110.

However, since most home network systems use a network address translator (NAT), communication with the first address information is not possible.

Therefore, when the registration server 230 receives the registration request message from the home server 110, the address information of the home server 110 changed by NAT through the sender address described in the header of the received registration request message (hereinafter, 2, called address information), and manage them together.

In addition, the registration server 230 checks whether the home server 110 has access authority by using the home server ID included in the registration request message, and performs registration processing. The address information (first address information and second address information) of the home server 110 registered with the extracted address information is updated.

In addition, the registration server 230 transmits a response message (VNAS_REG_RES) indicating the success or failure of the registration request to the home server 110 (S63). Therefore, the home server 110 confirms the success or failure of the registration request through the response message, and outputs an error message for the content since the home server 110 cannot provide contents in case of failure.

Subsequently, when the home server 110 is normally registered, the registration server 230 notifies the home server 110 of the content list (VNAS_PRG_LIST), which is information about content provided for a fee and free of charge from the content server 240. (S64). In this case, the content list may be prepared in a format such as Extensible Markup Language (XML).

The home server 110, which has received this, transmits a response message notifying that the content list has been normally received to the registration server 230 (S65).

In addition, the home server 110 uses the communication method of the in-house electromagnetic period according to the DLNA standard standard, and provides the in-house electronic device 120 connected to the home network 190 with service, device, and event characteristic information of the home server 110. ~ 170) (S66 ~ S68). That is, after transmitting the SSDP NOTIFY message to the home electronic devices 120 to 170 so that the home electronic devices 120 to 170 recognize the home server 110, the characteristics from the home electronic devices 120 to 170 are transmitted. In response to the information request, it transmits its own device, service, and event characteristic information. At this time, the home server 110 notifies the content providing function according to the present invention.

7 is a flowchart illustrating a procedure of providing a list of contents received from a home server to home electronic devices in the content providing system according to the present invention.

Referring to FIG. 7, when the content request message is received from the home electronic device 120 (S71), the home server 110 requests the content list received from the registration server 230 in FIG. 6. Provided by (S72). In this case, the request for content list and a response thereto may be made through SOAP. More specifically, the content list is requested through the SOAP ACTION Request message, and the content list is provided through the SOAP ACTION Response message. In this case, the home server 110 may provide a content list owned by the home server 110 as well as a content list received from the registration server 230.

In addition, the home server 110 may provide a streaming or copy service for content owned by the home electronic device 120 to 170.

That is, as illustrated in FIGS. 8 and 9, the home server 110 receives a reproduction request or a copy request for specific content included in the list from the home electronic device 120 that receives the content list (S81). If the requested content is held in the home server 110, the requested content is streamed or copied to the corresponding indoor electronic device 120 without a separate purchase procedure (S82 and S92). The streaming and copying service of the specific content may be performed through a SOAP ACTION REQUEST and a SOAP ACTION RESPONSE message.

On the other hand, the indoor electronic device 120 may request reproduction or copy of specific content included in the content list provided by the registration server 230. In this case, the home server 110 performs a purchase procedure with the content providing system 200 on behalf of the home electronic device 120.

10 and 11 are message flow charts illustrating a service procedure of paid content provided by the content providing system 200 in the content providing system according to the present invention.

Referring to FIG. 10, when a user wants to use paid content provided by the content providing system 200 while using the home electronic device 120, the user requests the corresponding content to the home server 110 using the DLNA standard. It may be (S1001). In this case, the request may be a content reproduction request or a copy request.

When the content requested by the home electronic device 120 is a paid content provided by the content providing system 200, the home server 110 may include a content ID, which is identification information of the corresponding content, and an identification information of the home server 110. The content request message (VNAS_PRG_REQ) including the device identifier is transmitted to the content server 240 (S1002).

The content server 240 checks whether the requested content is paid or free, and if it is paid, transmits a charging processing request message (VNAS_BILL_REQ) to the charging server 250 (S1003). Here, the charging processing request message includes a home server ID of the home server 110 requesting the content and a content ID.

The billing server 250 extracts billing information including a fee to be paid by the user based on the content ID, extracts the user's mobile communication terminal ID using the ID of the home server 110, and agrees to billing the user. Configure a text message requesting the request, and requests the message server 220 to transmit the configured text message (S1004). At this time, the mobile communication terminal ID to deliver the text message and the configured text message are delivered together.

Accordingly, the message server 220 transmits the text message configured in the charging server 250 to the mobile communication terminal 400 corresponding to the mobile communication terminal ID (S1005).

The user of the indoor electronic device 120 may check the charging information through a text message transmitted to the mobile communication terminal 400, and if the user agrees to the charging, the message server 220 through the mobile communication terminal 400. In step S1006, the mobile communication terminal 400 accesses the audio response server 210, and inputs a confirmation code through a voice telephone such as a voice mailbox (S1007). The audio response server 210 transmits the received confirmation code to the message server 220.

When the confirmation message is received or the confirmation code is input, the message server 220 transmits the confirmation message VNAS-MESSAGE_RES to the charging server 250 through the response message (VNAS-MESSAGE_RES) in response to the request for confirmation of charging agreement (S1008).

The charging server 250 checks whether the user agrees to charge in the received response message, and completes the charging process. In this case, the billing process may be performed in conjunction with a financial settlement system of a financial institution or a credit card provider, or may be made in the form of billing by adding to the usage fee bill of the mobile communication terminal 400. Since this charging process is generally well known, a detailed description thereof will be omitted.

After completing the billing process, the billing server 250 transmits a response message (VNAS_BILL_RES message) indicating whether billing is successful to the content server 240 (S1009).

When the charging success is answered, the content server 240 transmits a response message VNAS_PRG_RES that means accepting the content request to the home server 110 (S1010).

The home server 110 transmits the response to the content request of the content server 240 to the corresponding indoor electronic device 120 based on the DLNA standard action (SOAP Action Response) (S1011).

Thereafter, the content server 240 streams or copies the content corresponding to the requested content ID to the home server 110, and the home server 110 stores or simply passes the content to the home electronic device 120 ( S1012). Here, if the policy is determined to use the content without additional charges for a certain period, the content may be stored in the home server 110 and then managed to be viewed by other indoor electronic devices 130 to 170. In addition, when the set period of use of the serviced paid content elapses, it may be automatically deleted.

On the other hand, after transmitting a text message asking whether to accept the charging to the mobile communication terminal 400, the user may not agree to the charging within the set time.

FIG. 11 is a flowchart illustrating a procedure when a user does not agree to billing in the service process of paying content shown in FIG. 10, where steps S1101 to S1105 are the same as steps S1001 to S1005 of FIG. 10. .

That is, in response to a request from the home electronic device 120, a request message of a specific content is transmitted from the home server 110 to the content server 240, and a transmission of a text message requesting a billing request message and a billing consent is requested. After transmitting the text message asking the billing information and the billing consent from the message server 220 to the corresponding mobile communication terminal 400 of the corresponding user (S1101 to S1105), confirming that the billing is agreed from the mobile communication terminal 400. If the message is not received and the set time elapses (S1106), the message server 220 transmits the failure to confirm charging for the charge to the charging server 250 in the response message VNAS_MESSAGE_RES (S1107).

The charging server 250 confirming the failure of the charging agreement from the received response message does not perform charging processing for the requested content, and transmits the charging failure to the content server 240 in the response message VNAS_BILL_RES (S1108). .

When the content server 240 confirms the charging failure from the response message, the content server 240 does not perform the content service and transmits a response message VNAS_PRG_RES indicating that the service of the requested content is not available to the home server 110 (S1109).

The home server 110 transmits the received response message to the indoor electronic device 120 according to the DLNA standard (S1110).

12 is a message flow diagram illustrating a service procedure for free content provided by the content providing system 200.

Referring to FIG. 12, the home server 110 receiving a specific content request from the in-house electronic device 120 according to the DLNA standard generates a content request message (VNAS_PRG_REQ) including an ID and a home server ID of the requested content. The transmission is sent to the content server 240 (S1201 and S1202).

When the content server 240 receives the content request message and confirms that the corresponding content is free content through the content ID included in the message, the content server 240 immediately responds to the home server 110 without any charge request and includes an intention to accept the content request. The VNAS_PRG_RES is transmitted to the home server 110 (S1203).

The home server 110 confirms the intention to accept the content request in the received response message VNAS_PRG_RES and transmits it to the indoor electronic device 120 according to the DLNA standard (S1204).

Thereafter, streaming or copying of the content requested from the content server 240 to the indoor electronic device 120 through the home server 110 is performed (S1205). In this case, the home server 110 may simply transmit the data received from the content server 240 to the home electronic device 120, and store the received data in the internal storage space of the home server 110, and then DLNA. According to the standard may be provided to the home electronics (120).

Paid content provided by the content providing system 200 may have restrictions on copying. That is, the content providing system 200 may receive permission or pay an additional cost at the time of copying the content.

13 is a message flow diagram illustrating a copy confirmation procedure of paid content in a content providing system according to the present invention.

Referring to FIG. 13, the copy confirmation procedure of previously purchased paid content is performed in almost the same manner as the purchased content of paid content shown in FIG. 10. However, if the billing server 250 has a billing history for the corresponding content and the content is still valid, it is possible to perform an internal process of charging an additional billing, and at the same time as a new billing when the additional billing occurs. The process of seeking consent is the same. Thereafter, the contents stored in the home server 110 may be deleted and moved to the home electronic device 120 requested for copying, or the home server 110 may only copy the home electronic device 120 from the home server 110.

That is, when the home electronic device 120 requests the home server 110 to copy a specific content (S1301), the home server 110 is the paid content provided by the content providing system 200. If the stored paid content is still valid, the charging server 250 transmits an additional charge request message (VNAS_BILL_REQ) for copying the corresponding content (S1302). The additional charging request message includes the ID of the home server requesting the charging and the ID of the content to be copied.

The billing server 250 extracts information on the corresponding mobile communication terminal 400 of the corresponding user and a preset fee for copying of the corresponding content, constructs a text message asking for billing consent, and then recalls the configured text message. The message server 220 is requested to transmit to the mobile communication terminal 400 (S1303). The request message includes the ID of the mobile communication terminal 400 and the contents of the text message configured in the charging server 250.

The message server 220 transmits the text message transmitted from the billing server 250 to the corresponding mobile communication terminal 400 (S1304), and receives a confirmation message for the text message from the mobile communication terminal 400, or The confirmation code input through the voice mailbox is received through the audio response server 210 (S1305 and S1306).

After receiving the confirmation message or the confirmation code, the message server 220 transmits a response message (VNAS_MESSAGE_RES) including whether the charge is agreed to the charging server 250 (S1307). The response message includes the ID of the mobile communication terminal 400 that transmitted the text message.

The billing server 250 confirms whether or not the billing agreement is a response message, and completes billing processing for the copy service. Then, a response message (VNAS_BILL_RES) indicating that the processing for the charging request is completed is transmitted to the home server 110 (S1308).

The home server 110 transmits a response message indicating whether the copy request is possible to the home electronic device 120 according to the DLNA standard (S1309), and then moves previously stored contents to the home electronic device 120 or Copy (S1309).

In the copy confirmation process of the content as described above, since the content is stored in the home server 110, the intervention of the content server 240 is unnecessary.

However, for the copy service as described above, the process of confirming the charging agreement to the mobile communication terminal 400 may be cumbersome. In this case, since the consent for the billing was made in the initial purchase process, the consent process for the additional billing for copying may be omitted.

14 is a message flow diagram illustrating a copy confirmation procedure in which a billing consent process is omitted in the content providing system according to the present invention.

In FIG. 14, steps S1401 to S1402 are the same as steps S1301 and S1302 shown in FIG. 13. Subsequently, the billing server 250 that has received the billing request message for the specific content from the home server 110 has previously performed billing on the content to be billed, and if the content is still valid, Without the confirmation procedure, the home server 110 transmits a response message indicating that the processing for the billing request is completed to the home server 110 (S1203).

Accordingly, the home server 110 transmits a response message notifying the intention to accept the content request to the home electronic device 120 (S1205), and then copies or moves the previously stored content to the home electronic device 120. (S1405).

As described above, the content providing system according to the present invention may store the purchased content in the home server 110 and stream or copy the corresponding content to other indoor electronic devices 120 to 170. However, when the content stored in the home server 110 is copied to another indoor electronic device as described above, since the characteristics and the performance of the device are different for each indoor electronic device, the copied content may not be played or a problem may occur during playback. Can be.

Accordingly, the content providing system according to the present invention enables to provide content optimized according to the device characteristics of the home electronic device. Here, the optimized content refers to content whose size or format is converted to be stably reproduced in the indoor electronic device in accordance with the device performance of the indoor electronic device.

FIG. 15 is a message flow diagram illustrating a service procedure for providing contents optimized according to device characteristics of a home electronic device to be copied or moved when copying or moving purchased content in the content providing method according to the present invention.

Referring to FIG. 15, service procedures for providing optimized content (S1501 to S1512) are basically similar to the content service procedures (S1001 to S1012) shown in FIG. 10. The difference is that the billing server 250 charges the bill. When the information on the purchase information is notified to the content server 240, the content server 240 sends the content suitable for the device characteristics of the home electronic device 120 requested for copying to the home electronic device through the home server 110 again. 120).

When the home server 110 receives a copy or playback request for the specific content previously purchased from the home electronic device 120 (S1501), the home server 110 requests the corresponding content to the content server 240. The device further transmits device characteristic information of the electronic device 120 together with the ID and the content ID (S1502). The device characteristic information may be collected through a characteristic information request and response process according to the DLNA standard.

As described above with reference to FIG. 10, the content server 240 receiving the content request transmits a billing processing request message (VNAS_BILL_REQ) to the billing server 250, and the billing server 250 purchases the content for the corresponding content. After checking the facts, confirming whether the message server 220 and the mobile communication terminal 400 agree with the additional charging, and after confirming the charging consent from the user (S1503 to S1508), charging to the content server 240. By transmitting a response message to the request to notify that the billing process is completed, at this time, to inform the fact that the purchase already for the content (S1509).

The content server 240 transmits a response message to the home server 110, the response to the content request, based on the device characteristic information contained in the content request message received from the home server 110, and optimized for the device The provided content is provided back to the home server 110.

After receiving the response message to the content request, the home server 110 transmits a response to the request for copying or playing the content to the home electronic device 120 (S120), which is provided from the content server 240. The content optimized for the indoor electronic device 120 is transmitted to the corresponding indoor electronic device 120 (S1512).

According to this, the content viewed through the TV can be played on a portable terminal such as a mobile phone, and at this time, the corresponding content is optimized and provided in a form that can be used in the portable terminal.

The operation so far has been made in the state that there is no change in the configuration or function of the indoor electronic device and the mobile communication terminal according to the DLNA standard, according to this, to use the existing home electronic devices and mobile communication terminal as it is to service There is an advantage that it can. On the other hand, when the billing processing can be directly performed by the home electronic device, the mobile communication terminal, or the home server, the content service procedure can be simplified.

16 is a message flow diagram illustrating a content service procedure in the case where the mobile communication terminal 400 can directly communicate with the charging server 250 in the content providing system according to the present invention.

Here, it is assumed that the mobile communication terminal 400 can directly transmit and receive a charging related message with the charging server 250 without passing through the audio response server 210 or the message server 220.

In this case, when the home server 110 transmits a content request message to the content server 240 according to a content request of the home electronic device 120 (S1601 and S1602), the content server 240 may charge the billing server 250. The billing request for the requested content is requested (S1603).

The billing server 250 calculates a fee for the requested content, and then guides billing information including the fee and transmits a billing consent request message to the mobile communication terminal 400 requesting billing consent (S1604).

After receiving the billing consent request message, the mobile communication terminal 400 outputs the related information to the user through the user interface, receives a confirmation code for user authentication from the user, and transmits it to the charging server 250 (S1605). . The confirmation code may be delivered through a response message to the billing consent request.

The billing server 250 checks whether the confirmation code received from the mobile communication terminal 400 matches a pre-registered code, and if so, completes the billing process. In operation S1607, a response message to the charging request including whether the charging is successful is transmitted to the content server 240.

If it is recognized that the charging process is successful through the received response message, the content server 240 transmits a response message for accepting the content request to the home server 110 (S1608). The home server 110 notifies the indoor electronic device 120 that the requested content is provided according to the DLNA standard (S1609).

Thereafter, the content streamed or copied from the content server 240 is provided to the home electronic device 120 through the home server 110.

In this case, since the audio response server 210 and the message server 220 do not have to go through, the overall content service procedure may be simplified.

17 is a message flow diagram illustrating a service procedure in a case where a user authentication process for direct billing processing is performed in a home electronic device which has requested a content in the content providing system according to the present invention. Here, it is assumed that the home electronic device 120 requesting the content has a UI function for billing processing.

Referring to FIG. 17, when the home server 110 transmits a content request message to the content server 240 according to a content request of the home electronic device 120 (S1701 and S1702), the content server 240 is a billing server. In operation S1703, the client requests a charge for the requested content.

In this regard, the billing server 250 calculates a fee for the requested content, guides billing information including the fee, and sends a billing consent request message (VNAS_BILLCNF_REQ) asking for billing consent to the home electronic device 120 through the home server 110. (S1704).

After receiving the billing consent request message, the indoor electronic device 120 outputs the billing information received through the user interface to the user, receives a confirmation code for user authentication from the user, and receives the billing server through the home server 110. In step S1705, the processor 100 transmits to the step 250. The confirmation code is transmitted through a response message (VNAS_BILLCNF_ACK) for a billing consent request (S1706).

The billing server 250 receiving the confirmation code transmits to the in-house electronic device 120 through the home server 110 to notify that the billing consent confirmation has been successfully received (S1706).

On the other hand, the charging server 250 checks whether the confirmation code received from the home electronics 120 matches the pre-registered code, and if it matches, completes the charging process. In operation S1707, a response message for the charging request including whether the charging process is successful is transmitted to the content server 240.

If it is recognized that the charging process is successful through the received response message, the content server 240 transmits a response message to accept the content request to the home server 110 (S1708). The home server 110 notifies the indoor electronic device 120 that the requested content is provided according to the DLNA standard (S1709).

Thereafter, the content streamed or copied from the content server 240 is provided to the home electronic device 120 through the home server 110.

Next, FIG. 18 is a flowchart illustrating a content service procedure when the home server 110 has a UI function for inputting letters / numbers and is configured to communicate with the charging server 250.

Referring to FIG. 18, when a content request message is received from the home electronic device 120 (S1801), the home server 110 extracts billing information on the requested content, guides the extracted billing information, and asks for billing consent. The consent request message VNAS_BILLCNF_REQ is transmitted to the indoor electronic device 120 (S1802).

After receiving the billing consent request message, the home electronic device 120 outputs the billing information received through the user interface to the user, receives a confirmation code from the user, and includes the response message (VNAS_BILLCNF_ACK) in response to the billing consent request. The server 110 transmits the data to the server 110 (S1803).

The home server 110 receiving the confirmation code transmits the confirmation code to the home electronic device 120 to notify that the confirmation code has been successfully received (S1804).

Then, the home server 110 transmits a request message for the content to the content server 240 (S1805).

Accordingly, the content server 240 transmits a charge request message for the content to the billing server 250 (S1806), and the billing server 250 having received the billing agreement has already been made in the home server 110. In step S1807, after the charging process is completed, a separate message including the success or failure of the charging process is transmitted to the content server 240 without a separate charging consent procedure.

When the content server 240 recognizes that the billing process is successful through the received response message, the content server 240 transmits a response message for accepting the content request to the home server 110 (S1808), and in response to the DLNA standard by the home server 110. Accordingly, after the notification of providing the requested content is delivered to the indoor electronic device 120 (S1809), the content streamed or copied from the content server 240 is provided to the indoor electronic device 120 through the home server 110. .

Hereinafter, the operation of each device according to the content providing method for the home electronic device connected to the home network according to the present invention.

19 and 20 are flowcharts illustrating operations of the home server 110 according to the method for providing content according to the present invention.

Referring to FIG. 19, when power is applied and the initial operation is started, the home server 110 obtains the home server ID and its own address information (first address information) by identifying its own device information (S1901). .

Thereafter, the home server 110 configures a registration request message VNAS_REG_REQ to include the obtained home server ID and its address information, and then transmits the generated registration request message to the registration server 230 (S1902 and S1903).

After waiting for the response to the registration request message and receiving the response message (VNAS_REG_RES) for the registration request from the registration server 230 (S1904 and S1905), the contents of the received response message are checked and registration is successfully performed. Check whether it was made (S1906).

As a result of the check, if the registration fails, the operation is suspended (S1907).

On the contrary, as a result of the check, if the registration is successful, the list of paid and free contents which are continuously transmitted from the registration server 230 is received and stored (S1908). Then, a response message to the reception of the content list is transmitted to the registration server 230 to inform that the content list has been received.

Here, the content list delivered by the registration server 230 may be provided in the form shown in Table 1 below.

Start time Running time Content Name Rate Information Content properties More information 11:00 01:00 X1 free HD / SD - 20:00 01:00 X2 2000 won HD / SD -

That is, the content list includes one or more of the content characteristic information such as the start time of the content, the running time, the content name, the fee information expressed in the free or used amount, the image quality, and the like, and other additional information. Similarly, the content list management in the home server 110 is made in the form as shown in Table 1, and provides the above-described content list to the home electronic devices 120 to 170 based on the DLNA standard. The indoor electronic devices 120 to 170 may guide the received content list to the user through the UI. In addition, according to a user's request confirming this, a streaming or copy request message for specific content may be transmitted from the home electronic device 120 to the home server 110.

Referring to FIG. 20, when the home server 110 receives a streaming or copy request for specific content from the home electronics 120 (S2001), the home server ID as its identifier and the requested content are provided. A content request message including an ID is configured (S2002), and the configured content request message is transmitted to the content server 240 (S2003).

Thereafter, the home server 110 waits for a response to the request to be received from the content server 240 (S2004).

While waiting, if the response message for the content request is received from the content server 240 (S2005), the content ID and the response content (that is, whether to accept the content request) are extracted from the received message (S2006).

If it is determined that the content request is accepted in the response (S2007), a confirmation message for the streaming or copy request of the corresponding content is configured, transmitted to the indoor electronic device 120, and then the content serviced from the content server 240 To stream or copy to the home electronics (120) (S2010).

On the contrary, if it is determined that the content request is rejected in the response (S2007), the home server 110 notifies the home electronic device 120 of the rejection of the content request according to SOAP and ends (S2008).

In the above, when the content request is a copy request for previously purchased content, as shown in FIGS. 13 and 14, the home server 110 requests an additional charging process for copying to the billing server 250. Upon receiving the completion of the additional billing process from the billing server 250, the stored content is copied to the in-house electronic device 120.

In addition, when the home server 110, if necessary, the copy request for the previously purchased content, in step (S1902, S1903) further includes the device characteristic information of the electronic device 120 in the content request message sent to the content request message. In operation S2010, content optimized for the indoor electronic device 120 may be provided from the content server 240.

In addition, in addition to the above-described process, in some cases, as shown in FIG. 18, the home server 110 may further perform billing information guidance and billing consent processing for the requested content.

21 is a flowchart illustrating the operation of the registration server 230 according to the content providing method according to the present invention.

Referring to FIG. 21, when the registration server 230 receives a registration request message VNAS_REG_REQ from the home server 110 (S2101), the registration server message may include ID and address information (first address information) of the home server from the received registration request message. And second address information) (S2102). Here, since most home network systems use a network address translator (NAT), communication with the first address information included in the registration request message is not possible, so that the registration server 230 may be configured in the header of the received registration request message. The 2P address information of the home server changed by NAT is also extracted through the sender address.

Then, by checking the database of the registered home server through the extracted home server ID, it is checked whether the corresponding home server has access authority (S2103).

As a result, when the home server is a home server without access authority, the home server 110 transmits the error information to the home server 110 in the response message VNAS_REG_RES (S2104).

As a result of the check, if the home server 110 is registered and there is no problem, the extracted address information is updated with the current address of the home server (S2105), and the success message for the registration request is confirmed in the response message (VNAS_REG_RES). The response is sent to the home server 110 (S2106). When updating the address, not only the first address information of the home server 110 extracted previously but also the second address information are stored together.

Subsequently, the registration server 230 extracts a content list containing paid and free content information provided by the communication service provider to the home server 110 and transmits the content list to the home server 110 (S2107 and S2108). Then, in order to confirm whether the transmitted content list is successfully received, it waits for reception of a response message (S2109).

When receiving a response message indicating that the content list is received from the home server 110, the registration procedure is completed and ends (S2110).

The registration server 230 manages the home server 110 and the second address information that can communicate with the home server 110 provided in each home network system through the above-described registration process, and the home server 110 And other servers that communicate with the server, for example, the content server 240 or the charging server 240 to communicate with the second address information.

22 is a flowchart illustrating the operation of the content server 240 according to the content providing method according to the present invention.

Referring to FIG. 22, the content server 240 receives a content request message VNAS_PRG_REQ from the home server 110 (S2201). In this case, the content request may be a reproduction request or a copy request.

The ID of the requested content and the ID of the home server are extracted from the received content request message (S2202).

At this time, the content server 240 manages information on the serviced contents, such as Table 1 serviced.

Therefore, it is checked whether the requested content is paid content or free content using the content ID (S2203).

As a result of the check, if the free content is not necessary, the billing process is unnecessary, and therefore, a response message including the content of accepting the content request is immediately sent to the home server 110 (S2209).

Subsequently, the content server 240 provides the requested content to the home server 110 (S2210). In this case, the content may be provided in a streaming manner or in a download form.

On the other hand, if the requested content is the paid content, the content server 240 checks whether or not the home server 110 requesting the content for the billing process is a registered home server (S2204). This may be achieved through interworking with the registration server 230. If the home server 110 is not registered in this case, since the billing process is impossible, the home server 110 transmits an error message related thereto and ends (S2211).

When the home server 110 is registered, the content server 240 transmits a charging request message to the charging server 250 and waits for a response to the request (S2205 and S2206). The charging request message includes a home server ID that requested content and a content ID requested by the home server.

Thereafter, the billing server 250 may perform user consent confirmation and billing processing for billing.

When the billing process is completed, a response message for the billing request from the billing server 250 is transmitted to the content server 240 (S2207). Check (S2208).

As a result of the check, if the billing process fails due to unconfirmed user consent or other reasons, the content server 240 transmits an error message notifying the charge failure to the home server 110.

On the contrary, when it is confirmed that the charging process is successful from the response message, the content server 240 transmits a response message indicating that the content server accepts the content request to the home server 110 to provide the content (S2209), and then streams the requested content. Or it transfers to the home server 110 in a download manner (S2210).

In addition, the content server 240 may receive a content request message further including property information of a device on which content is to be reproduced in step S2201.

In this case, the content server 240 includes data of various formats for the same content. In operation S2210, when providing content, the content server 240 is based on device characteristic information extracted from the content request message. After searching for the optimal content that can be stably reproduced in the home server 110 may provide the searched content to the home server 110.

23 is a flowchart illustrating an operation of a charging server according to a content providing method according to the present invention.

Referring to FIG. 23, the charging server 250 receives a charging request message VNAS_BILL_REQ from the content server 240 or the home server 110 (S2301). In more detail, in the case of a streaming service for content, a charging request message is generated from the content server 240, and in the case of a copy request for content that is still valid, a charging request is generated from the home server 110. The charging request message includes the ID of the home server that requested the content and the requested content ID.

The billing server 250 extracts a home server ID and a content ID from the received billing request message, and grasps billing information (eg, content usage fee, etc.) for the request based on the extracted information (S2302).

Subsequently, a text message asking whether to agree to billing is configured based on the checked billing information (S2303).

Then, based on the home server ID, the mobile communication terminal ID of the pre-registered billing subject is checked, and the text message and the mobile communication terminal ID configured as the message server 220 are transmitted to request a text message transmission. Wait for a response (S2304). The message server 220 transmits the text message to the corresponding mobile communication terminal and transmits a response message indicating whether or not the billing agreement is confirmed according to whether a corresponding confirmation message or a confirmation code is received.

Therefore, when the charging server 250 receives the response message for the charging agreement request from the message server 220 (S2306), the charging server 250 checks whether the charging agreement is received from the received response message (S2303).

As a result of the check, if the billing agreement is successful, the billing server 250 performs the billing processing based on the previously known billing information and then records the processing result (S2310). Then, a response message notifying that the charging process is successful is transmitted to the device requesting the charging, that is, the content server 240 or the home server 110.

On the contrary, if the charging agreement is not confirmed, the charging server 250 transmits an error message corresponding to the charging failure to the content server 240 or the home server 110 (S2309).

24 is a flowchart illustrating an operation of a message server 220 according to a content providing method of the present invention.

Referring to FIG. 24, the message server 220 receives a request for transmission of a billing consent request text message from the billing server 250 (S2401). At this time, the ID of the mobile communication terminal to transmit the text message is received together.

After receiving the text message transmission request, the message server 220 extracts the mobile communication terminal ID and the text message content to transmit the text message (S2402), and transmits the extracted text message to the extracted mobile communication terminal, and then the billing agreement. Wait for the confirmation message or confirmation code to be received (S2403, S2404). Here, the password may be received through the audio response server 210 or transmitted in a text message form from the mobile communication terminal. At this time, the audio response server 210 checks whether the number is for the content billing when a call is made to the voice mailbox (or voice response) system, and if the number for the content billing is correct, the message server 220 inputs the code. To pass.

 In this state, the message server 220 measures the elapsed time after transmitting the text message, and if the confirmation message or the confirmation code for the charging agreement is not received from the mobile communication terminal until the set time has elapsed, the charging agreement confirmation is performed. A response message notifying that the failure has been transmitted is transmitted to the charging server 250 (S2405 to S2407).

When the confirmation message or the confirmation code for the charging agreement is received from the mobile terminal within the set time, a response message notifying that the charging agreement is confirmed is transmitted to the charging server (S2405 and S2408).

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be apparent to those skilled in the art.
