The personalization authentication server 225 receives the authentication request information including the SAID from the IPTV communication client at the time of terminal authentication, generates an authentication key (Unique Key, UK) from the IPTV communication client, and sends it to the IPTV communication client. Receives the authentication request information including the SAID and the PIN input by the user from the communication client, generates an authentication key (Unique Key, UK) from the communication client, and sends it to the IPTV communication client. If the already saved SAID, or SAID and PIN corresponding to the PIN already exists, sends the UK to the IPTV communication client. The detailed authentication process will be described later with reference to FIG.

The return path server 220 enables a bidirectional service by processing a request from an IPTV viewer, and in particular transmits an authentication request to the personalization authentication server 225 at the time of authentication.

The user who wishes to use the IPTV SMS service can select the IPTV communication service from the portal screen provided to the user's IPTV terminal 20 and then select the IPTV SMS service among the IPTV communication service. The portal screen is provided by a Data Broadcasting System (DBS) 235 and is loaded on a channel to which an IP has been assigned in a compression multiplexing system (or multiplexing system) 1 to the user's IPTV terminal 20 through the multicast network. The IPTV terminal 20 of the user may store the portal screen and display the portal screen on the screen of the IPTV terminal 20 after booting. If the version of the stored portal screen is the older version than the portal screen version currently provided in the data broadcasting system 235, the latest version after booting can be downloaded and displayed to the user. If the version is updated after booting, And informs the user IPTV terminal 20 of the information so that the user can update the portal screen version.

The connection front end server 101 establishes and maintains a connection session with the IPTV communication client on the IPTV terminal 20. [ The IPTV communication client requests the terminal authentication to the personalization authentication server 225. The terminal authentication request may be performed when the IPTV SMS service is selected, It is better to ask. After the main session is established by performing the authentication process, various notification messages from the IPTV SMS service system 500 can be received. A main session is established between the IPTV SMS service system 500 and the IPTV communication client of the IPTV terminal 20 when the terminal is authenticated after the authentication process. Through such a main session, a service that does not require personal authentication becomes available. That is, if the IPTV SMS service is implemented as a service requiring no personal authentication, if the SMS service is selected only in the main session state, the service can be performed without a process of inputting the PIN. In addition, when the IPTV SMS service is implemented as a service requiring personal authentication, when the SMS service is selected, the SMS session is established and the service becomes available when the user is logged in after the personal authentication is performed from the PIN input by the user. The connection session server 101 sets and maintains the main session, the SMS session, and the like.

The connection distribution server 102 plays a role of connecting a specific IPTV terminal 20 to a server at a proper one of a plurality of connection front-end servers 101.1 to 101.N.

The authentication server 103 verifies the validity of the authentication key (Unique Key, UK) generated by the above-described personalization authentication server 225 and performs authentication. As described above, the authentication using the IPTV terminal ID (SAID), that is, the UK verification in the terminal authentication can be performed. In the case where the IPTV SMS service is implemented as a service requiring personal authentication, It is also possible to perform UK verification in personal authentication using a personal identification number (PIN).

The SMS server 104 receives and stores the outgoing characters from the IPTV terminal 20, receives and stores the characters received from the IPTV terminal 20, and sends the stored characters to the IPTV terminal 20.

The intelligent network system 150 plays a role of appropriately distributing the SMS according to the reception number band when transmitting and receiving the SMS. For example, when a wire telephone number is assigned to the IPTV terminal 20, the intelligent network system 150 recognizes the identification number and allows the SMS to be received by the wire telephone number.

The intelligent network interworking server 105 plays a role of interlocking the SMS main system 100 so as to communicate with the intelligent network system.

The notification server 106 notifies the IPTV terminal 20 of the reception of the SMS through the connection front-end server 101.

The presence server 107 manages the login status using the SAID when authenticating the terminal, but when the IPTV SMS service is implemented as a service requiring personal authentication, the presence server 107 also processes login of the SMS service, Presence, i.e., a presence database (not shown) that can manage the connection state and stores such presence state. Also, when transmitting an SMS from the IPTV terminal 20.1 to another IPTV terminal 20.N, it is possible to determine whether the IPTV terminal 20N is connected.

The SMS gateway 160 plays a role of matching a protocol when transmitting SMS to another communication network, for example, an SMSC (SMS Center) 170 connected to a mobile communication network.

4 is a diagram illustrating a structure of an IPTV communication client 700 operated in the IPTV terminal 20 for implementing the IPTV SMS service according to the present invention. The IPTV SMS service system 500 and the IPTV communication client 700 are connected through an information communication network. The information communication network includes an Internet network and a multicast network as shown in FIG.

The communication main module 710 is a module for controlling each service module of the IPTV communication client 700 after establishing a main session with the IPTV SMS service system 500. The communication main module 710 performs the terminal authentication process. The terminal authentication may be performed when the IPTV SMS service is selected, but may be performed immediately after the IPTV terminal 20 is booted. After the main session is established by performing the authentication process, various notification messages from the IPTV SMS service system 500 can be received. That is, when the terminal authentication is requested to the personalization authentication server 225 as described above with reference to FIG. 3, the login is requested after the authentication server 103 has passed authentication, and then the login is requested, the SMS main body of the IPTV SMS service system 500 The main session is established through the system 100 and the connection front-end server 101. When the IPTV SMS service is implemented as a service requiring no input of a personal identification number (PIN), the IPTV SMS service can be immediately used only by setting the main session. Meanwhile, when the IPTV SMS service is implemented as a personalized service requiring input of a PIN, when the user selects the IPTV SMS service and inputs a PIN, the communication main module 710 transmits the personal authentication to the personalization authentication server 225 and requests the log-in after authentication by the authentication server 103 and logs in. When an SMS session is established through the SMS menu system 100 of the IPTV SMS service system 500 and the connection front-end server 101 . This is a session set up and maintained for the SMS service separately from the main session mentioned above.

If the IPTV SMS service is implemented so as to require individual authentication, the communication main module 710 performs terminal authentication and personal authentication to establish a communication main session and an SMS session as well as an SMS Module, it is necessary to set only the main session by the terminal authentication of the IPTV terminal 20. However, if the user desires to operate and control the SMS module without personal authentication at the time of selecting the SMS service do. For example, the user can request the IPTV terminal 20 through the remote controller 30 or the like. At this time, an observer module (not shown), which is a program module executed in the IPTV terminal 20, can recognize the inputted request, and the observer module can communicate with the communication main module 710 of the IPTV communication client 700 . The communication main module 710 thus driven drives the SMS control unit 721 to start the SMS service.

The SMS control unit 721 performs an SMS processing module 722.

The connection unit 723 is responsible for transmitting or receiving messages to / from the IPTV SMS service system 500.

The SMS processing module 722 is responsible for transmitting, receiving, and inquiring text messages. The SMS UI module provides a user interface for using the SMS service. The SMS transmission module transmits a text message input by the user to the IPTV SMS system (500) to the other party. The other party's phone number can be selected either by direct input or by inquiry of registered phone book. The SMS receiving module receives a text message. The notification server 106 informs the SMS main system 100 of the IPTV SMS service system 500 via the connection front end server 101 that a text message has been received. The SMS inquiry module is a module for requesting the IPTV SMS system 500 to provide a list of received or transmitted text messages and the contents of the text to the user.

In the IPTV SMS service system 500, one of the channels to be multicasted, that is, one IP, is allocated and a chat message input from all channels is transmitted. Therefore, it is necessary for the IPTV terminal 20 receiving the chat messages to select only the chat messages inputted from the channel currently viewed by the viewer. The multicasting data receiving module receives the data of the chat channel. This is the chat message data input on all channels as described above. In the SMS message extracting module, only the chat messages inputted from the channel currently viewed by the viewer are selected and displayed on the screen.

FIG. 5 is a diagram illustrating an authentication procedure when using the IPTV SMS service according to the present invention. Referring to FIG. 5, the IPTV terminal 20 requests authentication of a personalization authentication server (HDS) 225 and starts an authentication process (S501). Although not shown, the terminal authentication request is transmitted to the personalization authentication server 225 through the return path server system 220. The terminal authentication may be performed when the IPTV SMS service is selected, but may be performed immediately after the IPTV terminal 20 is booted. This is because it is possible to receive various notification messages from the IPTV SMS service system 500 after the main session is established by performing the authentication process. As described above with reference to FIG. 4, this is performed by the communication main module 710 of the IPTV communication client 700 performed in the IPTV terminal 20. The information included in the SAID request may include the SAID, which is the ID of the IPTV terminal, and application information. Since only the communication main module 710 is currently performed, the application information will be the IPTV communication service. The personalization authentication server 225 searches for existence of the SAID and the authentication key corresponding to the application information (Unique Key, UK), and returns the UK if it exists, (S502). ≪ / RTI > The IPTV communication client 700 of the IPTV terminal 20 requests connection connection server information to be connected to the connection distribution server 102 (S503). At this time, the access distribution server 102 may request a 'seed value' to encrypt the UK, SAID, etc. (S503). The connection distribution server 102 sends connection front-end server information to be connected to the IPTV communication client 700 (S504). If there is the 'seed value' request, the connection distribution server 102 may generate and send a 'seed value' S504). The IPTV communication client 700 generates a key encrypted with UK, SAID, etc. using the 'seed value', and transmits the key to an authentication server (not shown) in the SMS main system 100 of the IPTV SMS service system 500 (S505). The authentication server 103 verifies the received key value and sends the result to the IPTV communication client 700 (S506). If the authentication has been passed, the IPTV communication client 700 requests the login using the SAID (S507), and the connection front-end server 101 receiving the login request transmits the login request again to the presence server 107 S508). The login result is sent to the IPTV communication client 700 through the connection front end server 101 in steps S509 and S510 and the IPTV communication client 700 and the IPTV SMS service system 500 connect to the connection front end server 100 A main session for the communication service is formed through the network 101. [ The main session is managed by SAID.

If the IPTV SMS service is set to be serviced without personal authentication, the service can be used only by selecting an SMS service after the communication main session is established. That is, in this case, steps S511 to S521 to be described later are not necessary.

However, if the IPTV SMS service is set to be serviced only after personal authentication, the user enters a personal identification number (PIN) and selects a personal authentication process when selecting an SMS service. That is, in this case, when the user selects the IPTV SMS service and inputs the PIN, the communication main module 710 requests the personalization authentication server 225 for personal authentication (S511). Although not shown, the personal authentication request is also transmitted to the personalization authentication server 225 through the return path server system 220. The information included in the personal authentication request includes the SAID, the ID of the IPTV terminal, and the PIN entered by the user along with the application information. The personalization authentication server 225 searches for the existence of an authentication key (Unique Key, UK) corresponding to the SAID, the application information and the PIN, returns the UK if it exists, (Step S512). The IPTV communication client 700 generates a key encrypted with its UK or SAID and sends the key to the authentication server 103 for authentication (S513). The authentication server 103 verifies the received key value And sends the result to the IPTV communication client 700 (S514). The IPTV communication client 700 receives the ID and the password from the user at step S515 and requests the authentication server 103 for authentication and receives the result at steps S516 and S517. The presence server 107 sends an SMS log-in request to the IPTV communication client 700 (S520, S519). When the login is passed, SMS service becomes possible.
