<First Embodiment>

1 illustrates a configuration of a mobile communication system for processing an attached file included in a message according to a first embodiment of the present invention.

According to FIG. 1, the caller terminal 100 and the caller terminal 200 are terminals capable of providing a message service of a mobile communication network, and include a mobile phone, personal digital assistants (PDAs), and the like.

The sender terminal 100 and the receiver terminal 200 transmit and receive a message including an attached file in a message service of a mobile communication network. Here, the attached file includes multimedia data in a form executable in a mobile communication terminal such as an address book, a picture, an animation, a video, a ringtone, and the like.

Here, the message service of the mobile communication network includes a multimedia message service (MMS). At this time, the subscriber of the caller terminal 100 can take a video and record a voice using its own function (camera, etc.) and attach it to write an MMS message directly. Alternatively, an MMS message may be created by accessing a content provider server (not shown) that provides multimedia content through a mobile communication network. In addition, the called party terminal 200 is a terminal capable of receiving and executing an MMS message and extracting and executing an attached file included in the MMS message.

The exchange 300 performs call setting and release functions of the calling party terminal 100 and the called party terminal 200, performs various functions related to call processing and additional services, and performs interworking with other networks.

In particular, the exchange 300 is connected to the message service center 400 to provide a message transmission and reception path. That is, the message transmitted from the caller terminal 100 is transmitted to the message service center 400, and the message is received from the message service center 400 and transmitted to the called party terminal 200.

The message service center 400 collectively represents a configuration for providing a message service in a mobile communication network. In this case, the message service center 400 may include a multimedia message service center (MMSC).

The extension analyzer 500 is connected to the exchange 300 and / or the message service center 400 to provide extension probability information on the attached file. The extension analyzer 500 may be implemented as a separate server in a mobile communication network.

Here, the file extension is a part used to indicate the type of file and its role in the name of the computer file. Many operating systems recognize the extension of the file name after the last dot (.).

The extension analysis apparatus 500 receives an extension query for an attached file from the called party terminal 200 and transmits probability information of the extension to the called party terminal 200.

In this case, the extension analyzer 500 sets a data channel with the called party terminal 200 by a connection request from the called party terminal 200. The extension probability information may be transmitted by receiving a query for the extension of the attached file through the data channel.

In addition, the extension analyzer 500 may receive an extension query for an attached file by using a message service of a mobile communication network and transmit extension probability information. Here, the message service of the mobile communication network includes a short message service (SMS), a long message service (LMS), and a multimedia message service (MMS).

The analysis unit 540 analyzes the attachment included in the message received by the called party terminal 200 to predict the extension of the attachment.

Here, the technique for predicting the extension of the attached file is already known and implemented variously before this application, and there is a pattern matching technique. According to the pattern matching technique, the analysis result of the attached file pattern including the hexacode, the format, the structure, and the array is stored in the extension information DB 560 for each extension. For example, it analyzes and stores in advance the pattern information of an attached file of type 'mp3'. The probability of the extension of the attached file may be calculated by comparing the stored file pattern information.

At this time, the analysis unit 540 configures probability information including an extension having a highest priority probability and a probability of the extension.

In this case, a plurality of extensions and probability information for each extension may be calculated for the attached file which may be executed by mutually compatible applications and have similar file pattern information. In this case, the probability information may be sequentially arranged from the extension having the highest priority, and may be configured as a probability for each extension.

The extension information DB 560 stores file pattern information to which pattern information of a file having the extension is mapped for each predefined extension. In this case, the extension may include an extension of the text file 'txt', an extension of the executable file 'exe', 'com', 'bat', 'cmd' and the like.

The transmitter 580 transmits the probability information configured by the analyzer 540 to the called party terminal 200.
