It is sent through the channel. The voice call network matching unit 32 receiving the voice data transmits the voice data to the voice terminal 20 through the voice call network 50.

Through a series of processes performed in the video call service providing apparatus 30, when a call is performed between the voice terminal and the video terminal, the video terminal can receive the video call as if the other terminal is the video terminal. do.

4 is a diagram illustrating a procedure of providing a video call service during a call between an originating video terminal and an incoming voice terminal according to an embodiment of the present invention.

4 illustrates an example in which the calling terminal is a video terminal and the called terminal is a voice terminal. Referring to FIG. 4, when the calling video terminal attempts a video call, a video call call setup request signal is sent. The video call service providing apparatus 30 is transmitted to the video call service providing apparatus 30 through the W-MSC (S401), and the video call service providing apparatus 30 receives the incoming voice terminal corresponding to the video call call setting request signal received from the calling video terminal. The voice call call establishment request signal is transmitted to the destination voice terminal via the destination side exchange (MSC) in the same manner (S403). Here, the call network between the video call service providing device 30 and the calling video terminal is a video call network, and the call network between the video call service providing device 30 and the incoming voice terminal is a voice call network.

On the other hand, the video call service providing apparatus 30 transmits the preset video data to the calling video terminal via the calling switch (W-MSC) (S405). Here, the preset video data corresponds to a ring back tone in the case of a general voice call, and refers to the video data played by the calling video terminal until the called video terminal answers when the video call is attempted. Such video data may be set in advance by the user accessing the video call service providing apparatus 30 in advance. When the video call service providing apparatus 30 receives a voice call call setup response signal from an incoming voice terminal via the called side exchange (MSC) (S407), the video call service is established with the calling video terminal, and the incoming voice terminal is set. And establishes a voice call call (S409).

In step 409, the video call service providing apparatus 30 receives the voice data through the incoming voice terminal and the voice call by the set video and the voice call, and sets the received voice data in advance so that the video database 33 Video call data is generated by synthesizing with the video data stored in the terminal), and the generated video call data is transmitted to the calling video terminal. In response to this process, the video call service providing apparatus 30 makes a call through a video call. The video call data is received from the video terminal, the audio data is extracted from the received video call data, and the extracted audio data is transmitted to the called voice terminal (S411). Since the method of synthesizing the video call data and the method of extracting the audio data from the video call data in step 411 has been described with reference to FIGS. 2 and 3, description thereof will be omitted.

5 is a diagram illustrating a procedure of providing a video call service during a call between an originating voice terminal and a called video terminal according to another embodiment of the present invention.

FIG. 5 illustrates another example in which the calling terminal is a voice terminal and the called terminal is a video terminal. Referring to FIG. 5, when the calling voice terminal attempts a voice call call, the calling terminal is passed through an MSC. The voice call call setup request signal is transmitted to the video call service providing apparatus 30 (S501), and the video call service providing apparatus 30 sets up the video call call to the incoming video terminal corresponding to the received voice call call setup request signal. The request signal is transmitted (S503). On the other hand, the video call service providing device 30 transmits a ring back tone (ringback tone) to the calling voice terminal via the calling exchange (MSC) (S505), the ring back tone is a video call call setup response from the incoming video terminal The transmission continues until the signal is received.

When the video call service providing apparatus 30 receives a video call call setup response signal from the called video terminal via the called-side switch (W-MSC) (S507), the video call service providing apparatus establishes a voice call call and the incoming video terminal. And establishes a video call call (S509). In step 509, according to the set voice and video call call, the video call service providing device 30 receives voice data from an originating voice terminal via a voice call call and stores the received voice data in the video database 33. The video call data is generated by synthesizing with the stored video data, and the generated video call data is transmitted to the called video terminal via the called-side exchange (W-MSC). In response to the above-described process, the video call service providing apparatus 30 extracts voice data from the video call data received from the incoming video terminal, and transmits the extracted voice data to the calling voice terminal through the voice call network (S511). .
