Receivable mobile communication system is one of the important communication media indispensable in daily life.

In such a mobile communication system, mobile communication terminals are able to transmit predetermined text data within 80 bytes of each other by supporting a short message service (SMS). The amount of information that can be transmitted at a time is very large, and MMS has been developed and used to transmit not only text data but also various data including images, moving images and background music such as combined images and business cards.

In the general MMS method of transmitting MMS data using a mobile communication terminal, the mobile communication terminal is connected to the Internet by wire or wireless or by connecting to a computer by wire, and then downloads and stores predetermined MMS data. MMS data received from another mobile communication terminal is stored in advance and the MMS data to be transmitted is selected. Then, when the caller inputs the telephone number of the called party's mobile communication terminal to the mobile communication terminal and commands the transmission of the selected MMS data, the caller's mobile communication terminal transmits the MMS data together with the phone number of the called party's mobile communication terminal. Is transmitted to the mobile communication repeater, and the mobile communication repeater transmits the MMS data to the mobile communication terminal corresponding to the telephone number of the called party so that the called party can confirm.

The multimedia message service method in the mobile communication system according to the present invention as described above will be described in detail with reference to FIGS. 2 to 6 as follows.

First, in step S101, the calling subscriber terminal 110 creates an MMS message to be sent to the called subscriber terminal 160, and transmits it to the calling MMS server 120.

The originating MMS server 120 transmits a response to the MMS message to be sent from the originating subscriber terminal 110 to the called party in step S102, and the called party to which the called subscriber terminal 160 belongs in step S103. The MMS server 150 transmits the MMS message.

Next, the receiving MMS server 150 receiving the MMS message transmitted in step S104 performs a response to the calling MMS server 120, and notifies the called subscriber station 160 that the MMS message has arrived in step S105. do.

In step S106, the called subscriber station 160 notified of the reception of the MMS message transmits a response message to the called MMS server 150, and in step S107, information on the terminal (terminal capability) including the MMS message transmission method parameter. The incoming MMS server 150 transmits a request for searching for an incoming MMS message.

Here, as shown in FIGS. 3 to 6, when the subscriber subscriber station 160 selects an MMS transmission method (downloading, streaming, or conditional), the called subscriber terminal 160 sets the MMS transmission method corresponding to the selected MMS transmission method. Do it.

When an MMS message incoming notification is generated from the incoming MMS server 150, the preset MMS transmission method is searched, and when the terminal information is transmitted, the preset MMS transmission method parameter is sent to the destination MMS server 150. Will be sent.

Next, the receiving MMS server 150 receiving the information of the called subscriber station 160 in step S108 analyzes the MMS message transmission method parameter to determine the MMS message transmission method. As a result of this determination, when the MMS message transmission method is a download method, as shown in FIG. 3, the MMS message is transmitted to the called subscriber station 160 by the download method. In this case, the MMS message transmission method is performed through the same process as the well-known step S18 to step S22 of FIG. 1, and thus detailed description thereof will be omitted to avoid duplicate description.

On the other hand, if it is determined that the MMS transmission method is a streaming (streaming) method, in step S108 to transmit a Session Description Protocol (SDP) file for processing the streaming data to the destination subscriber station (160). . The SDP file here contains a description of the data to be streamed, such as a description of the session, the media type, and the media rate.

Next, the receiving subscriber station 160 receiving the SDP file in step S109 connects to the streaming server 130 through RTSP signaling. If the connection is established in step S110, the SGSN is determined according to 3GPP TS 23.060 in step S111. When the secondary PDP context is activated by the SGSN 140 in step S112, a request for transmission of MMS data to the streaming server 130 is requested in step S113.

In step S114, the streaming server 130 transmits streaming data (MMS data) to the called subscriber station 160 using the IP / UDP / RTP protocol.

After the reception of the streaming data in the terminating subscriber station 160, the service termination message is transmitted to the streaming server 130 in step S115, and responds to the streaming server 130 received in step S116 The session is released.

Next, in step S117, the terminating subscriber station 160 requests the SGSN 140 to deactivate the PDP context. In step S118, when the SGSN 140 deactivates the PDP context, transmission of the MMS message is terminated. .

On the other hand, in step S107, the receiving subscriber terminal 160 is notified of the incoming MMS message from the receiving MMS server 150, when the subscriber set the conditional (conditional) by the MMS transmission method as shown in Figs. If the MMS transmission method is determined. Here, the determination of the MMS transmission method may be determined according to the remaining memory size. Alternatively, the MMS transmission method may be determined in consideration of the environment of the mobile communication network. Alternatively, the MMS transmission method may be determined according to the subscriber's preference.

That is, when the MMS message size is larger than the size of the remaining memory by comparing the size of the MMS message with the size of the remaining memory, as shown in FIG. 6, the MMS transmission method is determined by the streaming method, and the MMS message size is determined by the size of the remaining memory. If it is smaller than the size, as shown in FIG. 5, the MMS transmission method is determined as a download method.

In addition, when the MMS transmission method selected by the called subscriber is conditional, the MMS transmission method is determined as a streaming method or a download method by reflecting a mobile communication network environment (for example, whether or not it is downloaded from a network or mobile communication network element environment). .

If the MMS transmission method is determined, to transmit the MMS message in the same process as the MMS message transmission process of the download method (S18 ~ S22) described in Figure 1 or the MMS message transmission process (S108 ~ S118) of the streaming method described in FIG. do.

As described above, according to the present invention "multimedia message service method in a mobile communication system", by allowing the mobile terminal to select a method of receiving a multimedia message, there is an effect of increasing the efficiency of the MMS message service.

In addition, by selecting a conditional transmission method when selecting an MMS transmission method, it is possible to select a transmission method suitable for a mobile communication environment and to transmit an MMS message to a subscriber.
