The stream of the broadcast service transmitted and stored in the internal device is transmitted to the user terminal for playback.

7A to 7H are flowcharts illustrating a method for controlling conversion of a tee communication convergence service which is a communication broadcasting convergence service in a wired / wireless converged network environment according to an embodiment of the present invention.

This is an overall flow chart of the t-communication convergence service control function. Referring to FIGS. 7A to 7H, the overall flow of the convergence service control is as follows.

First, the tee communication convergence service control function starts by turning on the power of the wired or wireless terminal capable of the television service owned by the user 1. When the power of the terminal is turned on, the wired / wireless call / session control function discovers the corresponding terminal connected to the network (701), accesses the integrated profile, and performs authentication to check whether the terminal is an available terminal (702).

If the authentication fails (703), the wired / wireless call / session control function transmits a terminal authentication failure message to the terminal (710). If the authentication succeeds (703), the wired / wireless call / session control function transmits a service list output request message requesting the user interface function to output the service list to the user terminal (704). Upon receiving the service list output request message (705), the user interface function accesses the service directory, constructs a list of available services (706), and transmits the service list to the wired / wireless call / session control function (707). Upon receiving the service list (708), the wired / wireless call / session control function transmits the service list to the user terminal (709).

The user selects the tee communication convergence service from the service list output to the user terminal which has received the service list (711) (712). The wired / wireless call / session control function receives the tee communication convergence service (713) and transmits it to the user interface function (714). The user interface function that has received the tee communication convergence service selection information from the wired / wireless call / session control function (715) sends a tee communication convergence service provision request message to the converged service control function (716).

The fusion service control function, which has received the tee communication convergence service provision request message (717), transmits the tee communication convergence service authentication request message to the fusion service management function to check whether the user can use the tee communication convergence service (718). The convergence service management function that receives the request for authenticating the tee communication convergence service (719) accesses the unified profile and authenticates whether the corresponding user can use the tee communication converged service (720).

If the authentication fails (721), the service authentication failure message is transmitted to the fusion service control function (731) and the received service (732), the fusion service control function transmits the service authentication failure message to the wired / wireless call / session control function (733). ). Upon receiving the service authentication failure message (734), the wired / wireless call / session control function transmits the message to the terminal (735).

Meanwhile, if authentication is successful (721), the authentication completion message is transmitted to the convergence service control function including the policy information which is the T communication convergence service performance information (722). After receiving the authentication completion message (723), the convergence service control function first sends a broadcast session establishment request message to the broadcast control function in order to set up the broadcast session to provide the broadcast service to the user terminal according to the policy information of the tee communication convergence service. Transmit (724).

The broadcast service control function that has received the broadcast session establishment request message (725) performs broadcast session setup and transmits the established broadcast session to the converged service control function (726). Upon receiving the broadcast session (727), the fusion service control function stores the broadcast session in the session for providing the tee communication fusion service of the user 1 in the internal storage space and changes the state to being in use (728). Then, the broadcast session establishment completion message is transmitted to the broadcast service control function (729). In response, the broadcast service control function receives a broadcast session establishment completion message (730).

The broadcast service control function receiving the broadcast session establishment completion message transmits the broadcast stream provided from the headend server to the content conversion function (736). Upon receiving the broadcast stream (737), the content conversion function transcodes the received broadcast stream appropriately for the terminal codec so as to be viewed by the terminal used by the user 1 and transmits it to the terminal (738). When User 1 is receiving a TV service, User 2 sends an instant message to User 1 (739), and the Instant Message server receives User 740's instant message (740), and transmits the instant message to the service broker function ( 741).

The service broker function receiving the instant message (742) accesses the unified profile to determine that User 1 is being provided with the tee communication convergence service (743) and sends the instant message to the converged service control function (744).

Receiving the instant message (745), the converged service control function sends (746) this instant message session establishment request message to the wired / wireless call / session control function for session establishment for the instant message. The wired / wireless call / session control function receives the instructor message session establishment request message (747).

Upon receiving the instant message session establishment request message, the wired / wireless call / session control function sets an instant message session and transmits the instant message session to the converged service control function (748). After receiving the instant message session (749), the fusion service control function stores the instant message session in the internal storage space and changes the state to being busy (750) among the session for providing the user's tee communication fusion service.

Then, the mobile device transmits an instant message session establishment completion message to the wired / wireless call / session control function (751). Receiving an instant message session establishment complete message (752), the wired / wireless call / session control function transmits the instant message to the terminal of user 1 (753). In this way, the user 1 can be provided with the instant messaging service while being provided with the television service. In this situation, when User 3 makes a Voice over IP (VoIP) call to User 1, the VoIP telephone service provision request is transmitted to the wired / wireless call / session control function (754).

Receiving a telephone service provision request (755), the wired / wireless call / session control function accesses the unified profile to determine that User 1 is receiving tee communication convergence service (756) and transmits the VoIP telephony service to the converged service control function. (757).

The converged service control function receiving the VoIP telephony service (758) determines that the user 1 is busy during the tee communication converged service session (759) and instructs the broadcast service control function to pause the broadcast stream transmission. The requesting broadcast stream pause request message is transmitted (760).

Receiving a broadcast stream pause request message (761), the broadcast service control function pauses (762) the broadcast stream transmission transmitted to user 1 and stores the broadcast stream coming from the headend server in the storage device (763). The broadcast stream pause completion message is transmitted to the convergence service control function (764). After receiving the broadcast stream pause completion message (765), the converged service control function changes the state of the broadcast session in the internal storage space to pause (766), and the VoIP telephone service session establishment request message is wired or wireless call / session control function. It sends to (767).

The wired / wireless call / session control function that has received a VoIP telephony service session establishment message (768) establishes a VoIP telephony service session and sends this VoIP telephony service session to the converged service control function (769). The converged service control function that receives the VoIP telephony service session (770) stores the VoIP telephony service session among user 1's tee communication convergence services in the internal storage space and changes the state to in use (771). Then, the VoIP telephone service session establishment completion message is transmitted to the wired / wireless call / session control function (772). The wired / wireless call / session control function receiving the VoIP phone service session establishment complete message (773) connects the VoIP phone to the terminal of user 1 (774).

When the user 1 hangs up the VoIP call, the wired / wireless call / session control function transmits the VoIP telephone service release message to the converged service control function (775). The converged service control function receiving the VoIP telephony service release message (776) changes the state of the VoIP telephony service session in the internal storage space to unused, changes the state of the broadcast session to active (777) and then broadcasts it to the broadcast service control function. A stream play request message is transmitted (778).

The broadcast service control function, which has received the broadcast stream reproduction request message (779), plays the broadcast stream, which has been paused, from the storage device (780) and transmits the played broadcast stream to the content conversion function (781). The content conversion function having received the broadcast stream (782) transcodes the received broadcast stream appropriately to the terminal codec so as to be viewed by the terminal used by the user 1 (783) and transmits it to the terminal.

3 shows the configuration according to the scenario in FIG. 3, when the user 1 turns on the terminal connected to the wired / wireless integrated network, the corresponding terminal is found in the wired / wireless call / session control function in the T-communication converged service control system. Access is performed to check whether the corresponding terminal is an available terminal. If the authentication succeeds, the user interface function is requested to output the service list to the user terminal. Receiving the service list output request, the user interface function accesses the service directory, constructs a list of available services, and transmits them to the wired / wireless call / session control function. The wired / wireless call / session control function having received the service list transmits the service list to the user terminal.

The user selects the tee communication convergence service from the service list output to the user terminal receiving the service list. The wired / wireless call / session control function receives the selected tee communication convergence service and transmits it to the user interface function. The user interface function receiving the selection of the tee communication convergence service from the wired / wireless call / session control function requires the fusion service control function to provide the tee communication convergence service. The fusion service control function receiving the request for providing the tee communication convergence service transmits a tee communication fusion service authentication request message to the fusion service management function to check whether the user can use the tee communication convergence service.

The convergence service management function that receives the request for authentication for the tee communication convergence service accesses the unified profile to authenticate whether the user can use the tee communication convergence service and, when the authentication is completed, includes the policy information, which is the information for performing the t communication convergence service, for authentication. Send the completion message to the fusion service control function.
