System for transmitting and receiving video messages between videophone terminal and non-videophone terminal, and control method thereof

The present invention relates to a video message transmission and reception system and a control method thereof, and more particularly, to a video message transmission and reception system between a video telephone terminal and a non-video telephone terminal and a control method thereof.

In general, mobile communication terminals such as mobile phones are made for the purpose of voice calls, but various functions have been implemented on the mobile communication terminals due to the development of terminal-related electronic technology and the improvement of the communication environment.

In particular, recently, it is possible to make a video call with the other party using a mobile communication terminal.

However, the video call is possible only if all the terminals of the party to be called support the video call function. If the other terminal does not support the video call function, the call is switched to the voice call method and is forced to make the voice call.

If it is irrelevant even if only the voice is transmitted, it is preferable to switch to the voice call method as described above. However, when it is desired to send predetermined video information, there is no proper means, which is a user complaint.

In particular, when the user terminal does not know in advance whether or not to support the video call to try to send the video information by the video call, the situation is switched to the voice call a number of times that the desired video information occurs, Thereafter, there is a need to transmit image data by using an additional key operation, for example, using a multimedia messaging server (MMS).

The present invention has been made to solve the above-mentioned problems, the purpose of which is to make a video call with the other party using a video telephone terminal, if the other terminal is a non-video telephone terminal video instead of a video call The present invention provides a video message transmission and reception system and a control method between a video phone terminal and a non-video phone terminal to be converted into a message form and transmitted.

In order to achieve the above object, a video message transmission and reception system between a video telephone terminal and a non-video telephone terminal according to the present invention comprises: a video telephone terminal for transmitting a video call call connection signal; When the video call call access signal is received from the video phone terminal, it is determined whether the target terminal of the video call call access signal is a terminal capable of video call, and if the non-video phone terminal does not support the video call, the video mailbox is switched. A video telephone server for transmitting a signal; A video mailbox for establishing a communication channel with the video telephone terminal according to the video mailbox switching signal, receiving and storing a video message corresponding to a video call from the video telephone terminal, and transmitting the stored video message to the non-video telephone terminal. It is configured to include a server.

In addition, in order to achieve the above object, a video message transmission and reception processing method between a video telephone terminal and a non-video telephone terminal according to the present invention comprises the steps of: transmitting a video call call access signal by a video telephone terminal having a video call function; When the video telephone server receiving the video call connection signal from the video telephone terminal determines whether the target terminal of the video call connection signal is a terminal capable of a video call, and the determination result is a non-video telephone terminal that does not support the video call. Transmitting a video mailbox switching signal; The video mailbox server establishes a communication channel with the video telephone terminal according to the video mailbox switching signal, receives and stores a video message corresponding to the video call from the video telephone terminal, and stores the stored video message in the non-video telephone terminal. It comprises the step of transmitting.

As described above, according to the present invention, when a user who wants to deliver information to the other party that cannot be properly delivered by voice alone, the user of the mobile communication terminal capable of a video call is not capable of the video call or the video call. It is possible to easily transmit the image information without considering whether the terminal is not.

In other words, if you want to transmit video information, if the other mobile communication terminal is a non-video phone terminal that is not capable of video calls, it can be automatically converted to a video mailbox and leave a video message. It is transmitted to the video phone terminal so that the other party can check the video, thereby increasing user convenience.

In addition, in consideration of the size of the video message to be sent can be transmitted in a streaming method can overcome the limitations on the memory capacity of the receiving terminal.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The video message transmission / reception system between the video phone terminal 100 and the non-video phone terminal 200 according to an embodiment of the present invention includes a video phone terminal 100, a non-video phone terminal 200, as shown in FIG. The base station 301, the base station controller 310, the PDSN 320, the video telephone server 400, the video mailbox server 500, the MMS server 610, and the SMS server 620 are configured to be included.

The video phone terminal 100 is a terminal capable of real-time video call. In order to make a video call with the other party, the video call terminal 100 must also be a video phone terminal 100. In this embodiment, the video phone terminal 100 is a mobile communication terminal of a sender who wants to transmit predetermined video information.

That is, when the user presses a video call key button, for example, for a video call, the video phone terminal 100 generates a video call call connection signal and transmits it to the video call server 400.

The non-video phone terminal 200 is a terminal used by a call receiver in the present embodiment and is a general mobile communication terminal without a real-time video call function. However, the non-video phone terminal 200 is not capable of real-time video call, but there is a function to run in real time after or without downloading and storing a video from a predetermined server or the like. For example, a video may be displayed by receiving and executing a multimedia file such as a video file.

The base station 301 forms a wireless channel with each mobile communication terminal such as the video phone terminal 100 and the non-video phone terminal 200 so that the mobile communication terminal can transmit and receive voice, video, and other wireless data. The base station controller 310 controls and manages at least one base station 301 to transmit a data packet or voice signal transmitted from each mobile communication terminal through the base station 301 to the PDSN 320 or MSC (switch: not shown). Perform the function of sending to. In this embodiment, each component is configured in the IP network by the PDSN 320 as an example, but may be built in the voice telephone exchange network connected to the MSC (not shown). In particular, the SMS server 620 and the MMS server 610 may be built in the voice telephone exchange network.

When the video call call access signal is received from the video call terminal 100, the video call server 400 determines whether the target terminal of the video call call access signal, i.e., the other party terminal, is the terminal capable of making a video call. In case of the non-video phone terminal 200 that does not support a video call, the video mailbox switching signal is transmitted to the video mailbox server 500.

An example of such a functional block of the video telephone server 400 is shown in FIG. 2.

As shown in the figure, the video telephone server 400 includes a communication interface unit 410, a control unit 420, and a determination unit 430.

The communication interface unit 410 is for communicating with host devices on an external network and may be, for example, a local area network (LAN) card.

The determination unit 430 determines whether the target terminal of the video call call access signal is a terminal capable of making a video call. Although the information on whether the video call is available for each mobile communication terminal may be already stored in the determination unit 430, It is also possible to determine whether a video call is possible through a database connection and a socket communication with an external server (not shown) having video call availability information of the mobile communication terminals. It may also be determined by transmitting and receiving a video call capable confirmation signal with the target terminal.

The controller 420 controls the communication interface 410 and the determination unit 430, and determines the call processing according to the determination result of the determination unit 430. That is, the determination result, if the other terminal is a terminal that supports the video call is connected to the video call call processing, if the other terminal is a terminal that does not support the video call transmits the video mailbox switching signal.

Here, the video mailbox switching signal is a kind of forwarding signal, which converts the call connection signal from the video telephone terminal 100 to the video mailbox server 500 so that the video message from the video telephone terminal 100 can be used instead of the video call. Performs a function to be stored in the video mailbox server 500.

The video mailbox server 500 is a server that allows a user such as a mobile communication terminal to store a predetermined video message as described above. When the video mailbox server 500 receives a video mailbox switching signal from the video phone server 400, the video phone terminal 100 is provided. It establishes a communication channel by transmitting and receiving a signal, and receives and stores a video message corresponding to a video call from the video phone terminal 100. In this case, the stored video message may be a compressed form of video data captured by the camera module of the video phone terminal 100 in real time. The compression algorithm can be configured in a variety of known ways.

An example of a functional block of the video mailbox server 500 is illustrated in FIG. 3. As shown in the figure, the video mailbox server 500 includes a communication interface 510 for communicating with an external network, a video mailbox 530 for storing video messages, and a controller 520. .

Here, the video mailbox 530 is designated for a caller who wants to transmit a video message, that is, a user of the video telephone terminal 100, and the user of the video telephone terminal 100 may set an access right of the video mailbox 530. have. For example, by configuring the authority to store multimedia data and the like to read the stored multimedia data separately in the video mailbox 530, the authentication process is performed during storage, and when the stored multimedia data is read, a different authentication process is performed. It can be done without.

As such, the video mailbox server 500 provides a video mailbox as a personal storage space to the user of the mobile communication terminal (video phone terminal 100), and when a predetermined video message is received from the video phone terminal 100, for example, K3G. Manage by saving in file format.

Subsequently, the control unit 520 of the video mailbox server 500 transmits a video message stored in the video mailbox 530 to the MMS server 610 to request delivery to a receiving terminal such as the non-video phone terminal 200.

The multimedia messaging service (MMS) server 610 is a server that provides a multimedia messaging service. When a request from the video mailbox server 500 is received, a video message is transmitted to the non-video phone terminal 200. Temporarily stores the video message received from the mailbox server 500, and requests the SMS server 620 to send a short message indicating the video message to the non-video phone terminal 200, the short message of the SMS server 620 When the video message transmission request is received from the non-video phone terminal 200 according to the message transmission, the temporarily stored video message is transmitted.

SMS (Short Message Service) server 620 is a server for transmitting a short message as described above, the short message transmitted to the non-video phone terminal 200 in the form of a predetermined text on the non-video phone terminal 200 Although the message may be displayed, it may be a message for notifying the non-video phone terminal 200 that multimedia data such as a video message is stored in the MMS server 610.

In general, when a user composes and transmits a text message or other multimedia message of 80 characters or more using a mobile communication terminal, the multimedia message is transmitted by the MMS server 610 (or a multimedia messaging service center) and the SMS server 620 (or a short message). The process of transmitting to the counterpart mobile communication terminal through the service center is known, but the MMS server 610 in the present embodiment receives the request from the video phone server 400 and processes the request of the conventional MMS server 610 This is different from the function.

Hereinafter, with reference to Figure 4 will be described in detail the control flow of the video message transmission and reception system between the video phone terminal 100 and the non-video phone terminal 200 according to an embodiment of the present invention.

First, when the user of the video telephone terminal 100 presses a video call button or the like to make a video call to the other party, the video telephone terminal 100 transmits a video call call connection signal to the video telephone server 400 (step S1). ).

Receiving the video call call connection signal, the video telephone server 400 determines whether the call connection target, that is, the other terminal, is a video telephone terminal capable of video call (step S2). Here, the video telephone server 400 may have its own database of whether or not each terminal can make a video call, and may be determined by data interworking with a terminal management server although not shown in the drawing. The detection signal may be sent, and it may be determined whether the video call support terminal depends on the detection signal.

If it is determined that the other terminal is a non-video telephone terminal 200 that does not support a video call, the video telephone server 400 transmits a video mailbox switching signal to the video mailbox server 500 (step S3). Here, the video mailbox switching signal is a kind of forwarding signal for converting the object connected to the video telephone terminal 100 from the counterpart terminal to the video mailbox server 500 so that the video message is stored instead of the video call.

The video mailbox server 500 receiving the video mailbox switching signal transmits a connection response signal to the video telephone terminal 100 via the video telephone server 400 (step S5 and step S6), and thus the video telephone terminal 100. The video mailbox server 500 may maintain a communication channel.

The video phone terminal 100 receiving the connection response signal from the video mailbox server 500 may display a message indicating that the other party terminal does not support the video call and is automatically switched to the video mailbox server 500 (step S6). ).

When the user of the video telephone terminal 100 that has confirmed the video mailbox switching message captures and inputs a video message to be delivered to the other party using a camera module (not shown) attached to the video telephone terminal 100 (step S7). ), The video phone terminal 100 transmits the captured video message to the video mailbox server 500 (step S8).

Here, the video mailbox server 500 includes a video mailbox in a space dedicated to the video message sender, and when the video message is received, stores the video message in the user's video mailbox (step S9). At this time, when registering / stored a predetermined video message in a video mailbox and reading a registered / stored video message, each authority may be changed according to a setting of a user who owns the video mailbox.

Since the data to be photographed is stored in the video mailbox server 500, the memory capacity of the video telephone terminal 100 is not large. In this case, the file format of the video message stored in the video mailbox server 500 may be, for example, a file format such as K3G, SKM, MP4.

After the storage of the video message is completed, the video mailbox server 500 requests the MMS server 610 to transmit the video message (step S10). The video message transmission request also includes a video message file.

Accordingly, after the MMS server 610 temporarily stores the video message file received from the video mailbox server 500 (step S11), a short message indicating that the video message has arrived at the SMS server 620 is called a counterpart terminal, that is, a non-video. Request transmission to the telephone terminal 200 (step S12).

When the SMS server 620 transmits the short message to the non-video phone terminal 200 (step S13), the non-video phone terminal 200 interprets the corresponding short message (step S14), and then transmits to the MMS server 610. A video message is requested (step S15).

Receiving a video message request from the non-video phone terminal 200, the MMS server 610 transmits the temporarily stored video message (step S16).

The video message stored in the video mailbox server 500 may be re-sent later to another counterpart according to a user's selection.

Meanwhile, the non-video phone terminal 200 stores the received video message and then displays the video message on the display unit of the terminal according to the user's selection so that the user can read it (step S17).

Hereinafter, a video message transmission and reception system between the video phone terminal 100 and the non-video phone terminal 200 according to another embodiment of the present invention will be described with reference to FIG. 5.

As shown in the figure, a video message transmission and reception system between a video telephone terminal and a non-video telephone terminal according to another embodiment of the present invention includes a video telephone terminal 100, a non-video telephone terminal 200, a base station 301, a base station The controller 310, the PDSN 320, the video telephone server 400, the video mailbox server 500, and the streaming server 630 are configured.

Here, since the remaining configuration except for the streaming server 630 corresponds to each configuration shown in FIG. 1, a detailed description thereof will be omitted.

The streaming server 630 corresponds to the MMS server 610 and the SMS server 620 of FIG. 1, and receives the video message transmission request from the video mailbox server 500, that is, the non-video phone terminal 200. It serves as a video message delivery.

That is, when the streaming server 630 receives a video message transmission request from the video mailbox server 500, the streaming server 630 transmits the presence of the video message using a WAP (Wireless Application Protocol) PUSH method and checks the corresponding message. 200) When there is a request for a video message from the non-video phone terminal 200 according to a user's key button operation, the video message received from the video mailbox server 500 and temporarily stored is stored in a non-video phone terminal 200 in a streaming manner. To transmit.

As such, the video message transmitted by the streaming method is not stored separately in the non-video phone terminal 200 but is output only in real time to a display unit such as an LCD (Liquid Crystal Display). Occurrence of a case can be prevented. That is, there is a case where the capacity of the video message is not large enough to be received by the receiving terminal, that is, the non-video phone terminal 200. In this case, if the video message is transmitted from the streaming server 630 in a streaming manner, the non-video phone terminal 200 In real time), the received video message is executed in real time, so that the user can read the video message through the display unit.

6 shows a control flow of the video message transmission and reception system according to another embodiment of the present invention.

Similar to the control flow of FIG. 4, but differs from step S13 ′ to step S17 ′. Hereinafter, a description of the same parts as the control flow of FIG. 4 may be omitted.

After receiving the video message transmission request from the video mailbox server 500, the streaming server 630 temporarily stores the video message (step S11), and then transmits a guide message to the non-video telephone terminal 200 (step S13 '). The guide message may include a message indicating that there is data to be transmitted and a URL of the streaming server 630. The guide message may be transmitted to the non-video phone terminal 200 in a WAP PUSH manner.

Here, the WAP PUSH is a method of forcibly transmitting predetermined information from the server end to the client end by using a wireless Internet protocol called WAP. In this way, a guide message may be received and displayed on the non-video phone terminal 200. (Step S14 ').

When the non-video phone terminal 200 requests a video message by a key operation of the user of the non-video phone terminal 200 that reads the guide message (step S15 '), the streaming server 630 stores the temporarily stored video message. In addition, the non-video phone terminal 200 executes / displays the corresponding video message in real time as soon as it is received so that the user can read it (step S17 ').

Meanwhile, in the above embodiments, the use of the MMS server 610 and the streaming server 630 has been described, respectively. However, the video message transmission and reception system between the video phone terminal and the non-video phone terminal according to the present invention may be combined with each other. Of course, it can be configured.

In this case, the video mailbox server 500 may check the capacity of the stored video message file and request a video message transmission to one of the MMS server 610 and the streaming server 630 according to the capacity of the file.

A brief control flow for this is shown in FIG. 7. In the description of the present embodiment, description of portions overlapping with the foregoing embodiment may be omitted.

As shown in the figure, after storing the video message (step S9), the video mailbox server 500 determines whether the file capacity of the stored video message is larger than the preset capacity (step S10). If it is determined that the file size of the video message is larger than the preset capacity, the video server transmits a request to the streaming server 630 (step S21), and if it is small, the video message transfer request to the MMS server 610 (step S21 '). .

Here, the preset capacity may be determined in consideration of the file size that the receiving terminal, that is, the non-video telephone terminal 200 can accommodate.

That is, if the capacity of the video message is larger than the capacity of the non-video phone terminal 200, the video message should be transmitted in the form of streaming to be executed immediately upon receipt without storing the video message. In this case, the video message to the streaming server 630. It is sending a request.

In FIG. 7, since the step after the video message transmission request is transmitted may correspond to each of the above-described embodiments, the illustration is omitted.

In the above embodiments, the video mailbox switching signal is transmitted to the video mailbox server 500. However, the video mailbox switching signal is transmitted to the video phone terminal 100 so that the video phone terminal 100 is connected to the video mailbox server 500. By request, the video phone terminal 100 and the video mailbox server 500 may be connected. That is, if the connection between the video telephone terminal 100 and the video mailbox server 500 can be made by the video mailbox switching signal generated from the video telephone server 400, the method may be included in the present invention no matter what process. .
