Power-On) and SIP service registration process. Through the process, it is determined whether the authentication and service use for the calling party / called party terminal (1, 2) (S100). In the SIP service registration process, the source / calling terminal (1, 2) sends a SIP request message via the multimedia session server (MSS) 3-1 to the IP multimedia service subscriber management device (IMSR) ( 3-2).

Subsequently, the originating terminal 1 transmits a message for requesting file transfer to the multimedia session server 3-1, and the multimedia session server 3-1 transmits a message. The request message is transmitted to the file transfer server (FTS) 3-3 (S101). At this time, it is preferable that the request message adopts an INVITE message defined in SIP.

At this time, the calling terminal 1 transmits its IP address, SIP address, called terminal number, calling terminal information, file information, etc. to the file transfer server (FTS) 3-3, and a file transfer server. Receives the IP address and SIP address of the file transfer server (FTS) 3-3. The originating terminal 1 may receive the authentication information of the FTP used for file transfer as needed.

Thereafter, the originating terminal 1 transmits a file by referring to the IP address of the received file transfer server 3-3 (S102). In this case, the transmitted file may be contents (for example, a game, music, or picture) downloaded from a content provider or a picture taken by a user using a terminal.

Thereafter, the file transfer server 3-3 checks the capability of receiving the transfer file of the called terminal 2, and then sends a request message according to the file transfer to the multimedia. It transmits to the called terminal 2 via the session server (MSS) 3-1 (S103). At this time, it is preferable that the request message adopts an INVITE message defined in SIP. In addition, the request message includes the IP address of the calling terminal, the SIP address of the calling terminal, and file information to be transmitted.

In addition to the above-described multimedia session server (MSS) 3-1, the multimedia session server (MSS) 3-1 indicates that an input message is an IP multimedia service message (SIP service registration and file transfer session). The IP multimedia service subscriber management device (IMSR) 3-2 and the file transfer server (FTS) after determining whether the message is a message related to a setting request) or a file transfer message (Calling Photo Message); SIP session control is performed by transferring to a File Transfer Server (3-3).

Thereafter, the file transfer server (FTS) 3-3 transmits the file with reference to the IP address of the called terminal (S104).

Thereafter, when the file transfer is completed, the file transfer server (FTS) 3-3 transmits a response message indicating that the file transfer is completed to the calling terminal 1. At this time, the response message is preferably adopted the INFO message defined in SIP.

On the other hand, the file transfer server (FTS) 3-3 sends the terminal information management server 4 to the capability of the called terminal using the called terminal number received from the calling terminal 1. Ask a question and receive a response. In this case, the capability information of the called terminal may be an LCD size, a pixel, an image display size, SIP protocol support, or the like of the terminal.

If there is no information (IP address) of the called terminal in the file transfer server (FTS) 3-3, the Calling Photo Server (CPS) 3-3 is the called terminal 2 It is assumed that the packet connection mode between the Calling Photo Server (CPS) and the Calling Photo Server (CPS) 3-3 is released, and to the called terminal 2 through the short message transmitting server 5 for reconnection attempt.

After the process up to step S102 is performed, the Calling Photo Server (CPS) 3-3 is a called terminal (ie, a called terminal in standby state) which cannot receive a transmission file immediately. The short message (SMS) requesting the client to receive the transmission file is transmitted through the short message transmission server 5 (S203). In this case, the short message may include a call-back URL that allows the called terminal to directly access the file using the 'call' button.

Thereafter, the called terminal 2 obtains the transmission file stored in the Calling Photo Server (CPS) 3-3 in the form of a Call-back URL using the HTTP protocol (S204).

Then, when the transmission of the file is completed to the called terminal 2, the Calling Photo Server (CPS) 3-3 sends a short message indicating that the file has been transmitted to the calling terminal 1 Send to (S205).

As a result, the file transfer system and the method during the voice call according to the present invention, regardless of the capability (capability) of the terminating terminal or even if there is no packet connection information of the terminating terminal or a picture taken by the terminal subscribers The photographed and stored picture may be transmitted to the called party during the voice call in the mobile communication network, and the downloaded contents (eg, game, music, picture) may be exchanged with the called party.
