It can be provided to the called party's mobile terminal. In addition, in order to provide various services, the video control server provides a video message service scenario to the calling mobile terminal, and accordingly, a video generated by recording video data input from the calling mobile terminal using the RTP packet through a SIP session. The message may be provided to the called-party mobile terminal via the SIP session.

At this time, the video message service scenario includes 1) recording / re-recording of video messages, 2) reading of sent video messages, 3) reading of received video messages, 4) reading of stored video messages, 5) video messages. At least one of the archiving function, 6) video message transmission function, and 7) usage guide or help function.

The messaging server is an application server that provides a video message service. When the generation of the video message is completed, the messaging server may receive the generated video message from the video message server. Therefore, the messaging server may transmit the video message received using the MRSP packet to the called mobile terminal through the second SIP session established at the called mobile terminal.

As described above, according to the present invention, the calling mobile terminal generates a video message through an IMS (IP Multimedia Subsystem) network and transmits the generated video message to the called mobile terminal, thereby enabling real time and high quality data transmission.

FIG. 2 is an exemplary diagram illustrating a detailed configuration of the image control server 160 shown in FIG. 1.

As shown in FIG. 2, the image control server 160 according to the present invention includes a session processor 210, a service processor 220, a data converter 230, a data transmitter 240, a database 250, and the like. It may include.

The session processor 210 may manage a SIP session by processing 3GPP IMS standard SIP signaling, and may receive an INVITE message through a CSCF to establish a SIP session according to a call connection request from an originating mobile terminal.

The service processor 220 may perform and manage a video message service to be performed after the SIP session is established. The service processor 220 provides a video message service scenario to the calling mobile terminal and selects one video message service scenario selected by the user. According to the recording function of the video data input from the calling mobile terminal can be recorded to generate a video message of a predetermined size.

The data converter 230 may perform codec conversion and size adjustment of the generated video message, and the database 250 may store the video message in which the codec conversion and size adjustment have been performed. This is to consider the function or performance of the called-party mobile terminal.

In addition, the data transmitter 240 may transmit a generated video message to the message server and request to transmit the video message to the called-party mobile terminal.

3 is a first exemplary diagram illustrating a method for transmitting a video message according to an embodiment of the present invention.

As shown in FIG. 3, the calling mobile terminal transmits an INVITE message to the video control server through CSCF, in particular, P-CSCF, S-CSCF, and SCIM, in response to a call connection request (S310). The control server may sequentially transmit the 180 ringing message and the 200 OK message to the calling mobile terminal (S312, S324).

In this case, the INVITE message may include an identifier of an image control server as a response identifier, and may be implemented in SDP or XML format to increase the efficiency of processing and transmitting the message. In addition, the identifier may include a unique Uniform Resource Identifier (URI), a Public Uniform Resource Identifier (URI), and the like.

The unique URI is the same concept as the International Mobile Subscriber Identify (IMSI) in the WCDMA system, and may follow a network access identifier Network Access Identifier (NAI) structure. In addition, the public URI may follow the SIP-URI structure or the TEL-URI structure as the same concept as the International Mobile Subscriber ISDN Number (MSISDN) in the WCDMA system.

On the other hand, if the video control server does not accept the call connection request in response to the INVITE message, it may generate a rejection response message and transmit it to the calling mobile terminal.

When the calling mobile terminal receives the 180 ringing message and the 200 OK message, the calling mobile terminal may generate a SUBSCRIBER message for notifying that the call is connected and transmits it to the image control server (S316). This is to inform the video control server not to receive another call connection request because the calling mobile terminal is already connected.

When the setting of the first SIP session is completed as the video control server receives the SUBSCRIBER message, the video control server may automatically activate the recording function of the video message and receive the image data using the RTP packet through the set first SIP session ( S318). In addition, the video control server transmits a video message service scenario to the calling mobile terminal. For example, if the recording function of the video message is selected, the recording function of the selected video message is activated. Video data can also be received using RTP packets.

Thus, the image control server may record the input image data to generate a video message having a preset size (S320). In addition, the image control server may store the generated video message in a database, or may store the generated video message after codec conversion or resizing.

Thereafter, the video control server may provide the generated video message to the called-party mobile terminal. In this case, the video control server transmits an INVITE message to the called mobile terminal through SCIM and CSCF, in particular, S-CSCF and P-CSCF according to a call connection request for transmitting a video message (S330), and responds thereto. The called-party mobile terminal can sequentially transmit a 180 ringing message and a 200 OK message to the image control server (S332, S334).

When the called-party mobile terminal transmits a 180 ringing message and a 200 OK message, it can generate a SUBSCRIBER message for notifying that the call is being connected to the image control server (S336). This is to inform the video control server not to receive another call connection request because the called mobile terminal is already connected to the call.

Upon receiving the SUBSCRIBER message, the video control server completes the setting of the second SIP session and transmits the video message recorded using the RTP packet to the called-party mobile terminal through the set second SIP session (S338). As a result, the called-party mobile terminal can receive the video message from the calling-party mobile terminal in real time and display it.

As described above, since the present invention transmits a large-capacity and high-definition video message through the IMS network, the user's satisfaction using the video message service can be improved.

4 is a second exemplary diagram illustrating a method for transmitting a video message according to an embodiment of the present invention.

As shown in FIG. 4, the calling mobile terminal transmits an INVITE message to the video control server through CSCF, in particular, P-CSCF, S-CSCF, and SCIM, in response to a call connection request (S410), and in response to the video. The control server may sequentially transmit the 180 ringing message and the 200 OK message to the calling mobile terminal (S412, S414).

When the calling mobile terminal receives the 180 ringing message and the 200 OK message, the calling mobile terminal may generate a SUBSCRIBER message for notifying that the call is connected and transmits it to the image control server (S416).

When the setting of the first SIP session is completed as the video control server receives the SUBSCRIBER message, the video control server may automatically activate the recording function of the video message and receive the image data using the RTP packet through the set first SIP session ( S418). In addition, the video control server transmits a video message service scenario to the calling mobile terminal. For example, if the recording function of the video message is selected, the recording function of the selected video message is activated. Video data can also be received using RTP packets.

Thus, the image control server may record the input image data to generate a video message having a preset size (S420). In addition, the image control server may store the generated video message in a database, or may store the generated video message after codec conversion or resizing.

Thereafter, the video control server may transmit the generated video message to the messaging server and request to transmit the transmitted video message to the called-party mobile terminal (S430). Of course, if the incoming phone number is not provided at the time of call connection of the calling mobile terminal to transmit the video message to the called mobile terminal, it can be provided by requesting it.

The messaging server may provide the generated video message to the called-party mobile terminal. In this case, the messaging server transmits an INVITE message to the called mobile terminal through SCIM and CSCF, in particular, S-CSCF and P-CSCF according to a call connection request for transmitting a video message (S440), and in response thereto. The called-party mobile terminal can sequentially transmit a 180 ringing message and a 200 OK message to the messaging server (S442, S444).

When the called-party mobile terminal transmits a 180 ringing message and a 200 OK message, it can generate a SUBSCRIBER message for notifying that it is connected to the call and send it to the messaging server (S446). Similarly, this is to inform the messaging server not to receive another call connection request because the called mobile terminal is already connected.

Upon receiving the SUBSCRIBER message, the messaging server completes the establishment of the second SIP session and transmits the video message received using the MRSP packet to the called-party mobile terminal through the established second SIP session (S448). As a result, the called-party mobile terminal can receive the video message from the calling-party mobile terminal in real time and display it. In particular, since the video message is automatically stored in a separate video message mailbox like an existing SMS message or MMS message, the user can display the video message by selecting the stored video message if desired.

The system and method for providing a video message service according to the present invention can be modified and applied in various forms within the scope of the technical idea of the present invention and are not limited to the above embodiments. In addition, the embodiments and drawings are merely for the purpose of describing the contents of the invention in detail, not intended to limit the scope of the technical idea of the invention, the present invention described above is common knowledge in the technical field to which the present invention belongs As those skilled in the art can have various substitutions, modifications, and changes without departing from the technical spirit of the present invention, it is not limited to the above embodiments and the accompanying drawings, of course, and not only the claims to be described below but also claims Judgment should be made including scope and equivalence.
