FIG. 5 illustrates an embodiment of a process of storing conversation contents performed in the conversation contents storage system of FIG. 4.

The illustrated conversation content storage method is performed between a mobile terminal, an instant message server, and a database server, and the steps performed by the mobile terminal may be performed by a controller of the mobile terminal.

Referring to FIG. 5, a user of the mobile terminal starts a conversation using an instant messenger. The user requests to save the conversation contents through an instant messenger (S500). The user's request means generating a signal for storing conversation contents using a user input unit. Each time the user requests the storage of the conversation contents, the controller stores information in the memory including an arbitrary title assignment and a conversation contents storage date and time. The user may generate an operation signal using a key, a touch screen, voice recognition, or the like. The mobile terminal converts the conversation content into XML data in RSS format (S501). The format of the XML data of the RSS format has been described above, and the details may include a user ID, a counterpart ID, a conversation content, a conversation date / time, and the like. The mobile terminal transmits the XML data of the RSS format to the instant message server using the Internet (S502). The instant message server analyzes the received XML data of the RSS format (S503). The instant message server generates a URL address for storing conversation contents and related information in a database (S504). That is, it means the address of the <link> http://ooo.mychat.com / 000001 </ link> portion of the XML data portion of the RSS format. In the above description, '000001' corresponds to an address for storing the conversation contents and the related information. Each time a user of the mobile terminal requests to save the conversation contents, the address is newly generated. The instant message server transmits the analyzed or XML information of the XML format of the RSS format to the database (S505). The database stores information obtained by analyzing XML data of the RSS format, user information, and the like in a storage area corresponding to the URL address (S506). When the storage is normally completed, the database transmits a message indicating that the storage is completed to the instant message server (S507). The instant message server transmits a message indicating that the storage is completed to the mobile terminal through the Internet (S508). The mobile terminal displays a message indicating that the storage is completed (S509).

The process of storing the conversation contents can be modified. In one embodiment of the modification, the user requests the storage of the conversation contents through an instant messenger (S500). The mobile terminal transmits the information including the contents of the conversation to the instant message server. The instant message server executes the processes S501 and S502 and transmits XML data in RSS format to the database. The database executes the processes S503, S504 and S505. In this case, the database may mean a database server including the concept of the controller.

In another embodiment, the steps S500, S501, and S502 are executed in the mobile terminal, and transmit XML data in RSS format to the instant message server. The instant message server sends the received XML data in the RSS format to the database. The database executes the processes S503, S504 and S505. As described above, the process of converting and analyzing the conversation content into XML data in RSS format can be variously modified.

Before the step S500, the user of the mobile terminal starts an instant messenger, and the user inputs authentication information. The mobile terminal transmits the user authentication information to the instant message server. The instant message server verifies whether the user is a legitimate user using the user authentication information. As a result of the verification, if the user is a legitimate user, the instant message server transmits a message to the mobile terminal to permit the use of the instant messenger. Through this process, a process of authenticating a user may be further included.

FIG. 6 illustrates an embodiment of a process of receiving a conversation content performed in the conversation content storage system of FIG. 4.

Referring to FIG. 6, a user of a mobile terminal requests an inquiry of conversation contents to be viewed from a list of conversation contents stored through an instant messenger (S600). The user's request means generating a signal for searching stored conversation contents using a user input unit. The stored conversation contents list means a list arranged to view the stored information at once. The stored conversation contents list is configured by reading information including a plurality of conversation contents stored in the memory 160. The mobile terminal may use a terminal other than the terminal used to store the conversation contents. The user may also use a computer instead of the mobile terminal. The mobile terminal requests the instant message to the instant message server (S601). The request can be made by accessing a URL address where the selected conversation content is stored. For example, the URL address refers to an address such as OOO.mychat.com/000001. The instant message server requests the selected conversation content from the database (S602). The database transmits the information including the requested conversation content to the instant message server (S603). The transmitted information may include not only the contents of the conversation but also an ID of the user, an ID of the other party, a date / time in which the contents of the conversation are stored. The instant message server converts the information including the requested conversation content into XML data in RSS format (S604). The instant message server transmits XML data of the RSS format to the mobile terminal (S605). The mobile terminal analyzes the received XML data of the RSS format (S606). The mobile terminal displays the analyzed information on the output unit (S607). The analyzed information may include a conversation counterpart ID, a date / time at which the conversation contents are stored, conversation contents, and the like.

The process of converting and analyzing the information including the conversation contents into the XML data of the RSS format may be variously modified in the location executed as in the process of storing the conversation contents mentioned in FIG. 5.

Before the step S600, the user of the mobile terminal starts an instant messenger, and the user inputs authentication information. The mobile terminal transmits the user authentication information to the instant message server. The instant message server verifies whether the user is a legitimate user using the user authentication information. As a result of the verification, if the user is a legitimate user, the instant message server transmits a message to the mobile terminal to permit the use of the instant messenger. Through this process, a process of authenticating a user may be further included.

Another way to check the conversation is by using an RSS reader. The user can check the stored conversation contents without using the messenger using the distributed RSS reader program.

According to the present invention, due to the limitation of the storage capacity of the mobile terminal, inconvenience such as the limitation of the number of long conversation contents that cannot be stored or the number of storages can be eliminated.

In addition, when the conversation contents are stored in the mobile terminal and the mobile terminal is replaced, the user may not be able to confirm the stored conversation contents or the inconvenience of having to copy them separately may be solved.

In addition, since the conversation contents stored by using a mobile terminal or a computer other than the mobile terminal used for storing the conversation contents may be received, the conversation contents may be easily checked by using a desired place and device. .
