1 is a diagram illustrating an example of a mobile communication system providing a mobile messenger service to which the present invention is applied. Referring to FIG. 1, a mobile communication system for providing a mobile messenger service (hereinafter, abbreviated as 'mobile messenger system') includes mobile communication terminals 100, 500, and 600, and a short message service providing server ( In the following description, the term "SMS server" 200, a packet data core network 300, and a packet data serving node 400 will be described.

The mobile communication terminals 100, 500, and 600 are terminals provided with a program for a mobile messenger service, and a host terminal 100 transmitting an invitation message for a conversation invitation and an acceptance message for accepting a conversation in response to the invitation message. Client terminals 500 and 600 that transmit the data.

The SMS server 200 provides a short message transmission service through a mobile communication network (eg, a CDMA network). In particular, the invitation message of the host terminal 100 is transmitted to the client terminals (500, 600).

The packet data core network 300 establishes a point to point protocol (PPP) communication channel to perform packet data communication.

The PDSN 400 is connected to each of the host terminal 100 and the client terminals 500 and 600 through the packet data core network 300, so that the PDSN 400 receives the accept message transmitted from each of the client terminals 500 and 600. Deliver to 100. And it provides a mobile messenger service after the initialization for the mobile messenger service. That is, a real time information transmission service is provided between the host terminal 100 and the client terminals 500 and 600. For example, the information message input by the host terminal 100 is transmitted to the client terminals 500 and 600, and the message input by the client terminal 500 is transmitted to the host terminal 100 and the client terminal 600. The client terminal 600 transmits the message input to the host terminal 100 and the client terminal 500.

An example of a messenger service performing procedure using the mobile messenger system having such a configuration is illustrated in FIG. 2.

FIG. 2 is a diagram illustrating a messenger service performing procedure using the mobile communication system illustrated in FIG. 1. In particular, FIG. 2 illustrates an example of an initialization process for a mobile messenger service between the host terminal 100 and the client terminal 500.

Referring to FIG. 2, an example of the process is as follows.

First, the host terminal 100 maintains an operation mode for mobile communication at normal time and drives a mobile messenger program when a command for a mobile messenger service is input (S105).

After generating a buddy list based on user selection information (S110) and performing a point-to-point protocol connection with the PDSN 400 (S115), the IPSN from the PDSN 400 is referred to as Internet Protocol (hereinafter referred to as 'IP'). The address is assigned (S120).

At this time, the 'buddy list' is a list (aka, contact list) for users who want to conduct a conversation through the mobile messenger service. It is preferable that the host terminal 100 generates a buddy list after selecting among the mobile messenger conversation schedulers registered in the host terminal 100 to be included in the conversation as a conversation partner. However, it is also possible to include information for identifying a mobile messenger service-enabled user in the general address book of the host terminal 100 and to select a conversation partner among the mobile messenger service-enabled users from the general address book.

As such, the host terminal 100 generating the buddy list transmits an invitation message to each of the terminals corresponding to the chat partner registered in the buddy list. 2 illustrates an example of sending an invitation message to the client terminal 500. 2 illustrates an example of registering a user corresponding to the client terminal 500 in a buddy list in step S110 and transmitting an invitation message to the client terminal 500 in steps S125 and S130. Doing. The invitation message transmission process (S125, S130) is made through the SMS server 200, and transmitted by including the IP address of the host terminal 100 obtained in the process (S115) in the invitation message. In this case, the invitation message may further include ID information and port number information of the host terminal 100 in addition to the IP address.

Then, the client terminal 500 receiving the invitation message determines that the type of the received message is a message for a mobile messenger service and drives a messenger program (S135). In operation S140, information on the host terminal 100 is detected from the invitation message. That is, the client terminal 500 detects ID information and port number information of the host terminal 100.

In addition, the client terminal 500 performs a point-to-point protocol connection with the PDSN 400 (S145), receives an IP address from the PDSN 400 (S150), and then accepts the invitation message based on user selection information. It is transmitted to the host terminal 100 (S155, S160).

At this time, since the client terminal 500 already knows the IP address of the host terminal 100 when receiving the invitation message (S130), the client terminal 500 sends an acceptance message to the host terminal 100 through the PDSN 400 using the IP address. To pass. That is, by generating an accept message having its own IP address as a source address and an IP address of the host terminal 100 as a destination address, and transmitting it to the PDSN 400, the accept message is transmitted to the host terminal 100. do. In the meantime, the acceptance message preferably includes protocol information, port number information, and authentication information in addition to the IP address.

Then, the host terminal 100 updates the buddy list to include only the information of the client terminal 500 transmitting the acceptance message (S165). That is, the host terminal 100 deletes the user of the terminal that has not sent an acceptance message in response to the invitation message from the buddy list.

The buddy list updated in the step S165 is transmitted to the client terminal 500 which has sent the acceptance message (S170 and S175). At this time, the host terminal 100 transmits a buddy list through the PDSN 400.

As such, when the buddy list is shared between the conversation partners, the mobile messenger service using each IP address is started (S180). That is, the mobile messenger service is started by each of the conversation partners accessing the PDSN 400 using the IP address.

3 is a flowchart illustrating a file transfer method according to an embodiment of the present invention. That is, FIG. 3 is a process for completing the initialization for the mobile messenger service through the process illustrated in FIG. 2 and transmitting the file to the client terminal 500 by the host terminal 100 using the mobile messenger service. An example is shown.

Referring to FIG. 3, when a file transfer request is input to the host terminal 100 in a state in which a messenger is connected between the host terminal 100 and the client terminal 500 (S205), the host terminal 100 may request transmission. The file is loaded (S215). That is, when a file transfer request signal for transmitting a file accessible through the host terminal 100 to the client terminal 500 through the packet data communication network is received, the host terminal 100 sends the corresponding file in response to the file transfer request signal. Load.

In this case, the file transfer request may be a file previously stored in the internal memory of the host terminal 100 or a file stored in an external device to which the host terminal 100 can connect to a wireless communication network (eg, wireless Internet).

If the file transfer request is directed to a file stored in an external device that the host terminal 100 can access through the wireless communication network, the host terminal 100 accesses a file to be transmitted through the wireless communication network in step S215. After that, it is preferable to load the file. On the other hand, when the file transfer request targets a file previously stored in the internal memory of the host terminal 100, the host terminal 100 may load the file to be transmitted from the internal memory in step S215.

In operation S215, the host terminal 100 that has loaded the file to be transmitted transmits a file transmission request message to the client terminal 500 (S220). When a response message indicating that the file transfer request is accepted is received from the client terminal 500 (S225 and S230), a socket connection request message for file transfer is transmitted to the client terminal 500 (S235). When the connection acceptance message is transmitted from the client terminal 500 (S240), the socket is connected to the client terminal 500 in response thereto. At this time, it is preferable that the socket to be connected is a TCP / IP socket. This is to prevent data loss or corruption due to poor communication conditions.

As such, when a socket is connected between the host terminal 100 to transmit a file and the client terminal 500 to which the file is to be transmitted, the host terminal 100 transmits the corresponding file through the socket (S245). That is, the file loaded in step S215 is transmitted.

In the process (S245), each of the host terminal 100 and the client terminal 500 grasps the file transfer progress and displays the file transfer progress to the host terminal 100 and the client terminal 500, respectively. Do.

On the other hand, when the file transfer of the host terminal 100 is terminated (S250) and the file reception of the client terminal 500 is terminated (S255), the client terminal 500 transmits the transmission result to the host terminal 100, and the host The terminal 100 preferably further performs a process of displaying the received transmission result.

When the acceptance message for the file transfer request is transmitted from the other mobile communication terminal (for example, the 'client terminal 500' of FIG. 3), another mobile communication terminal (for example, the 'client of FIG. 3) is responded to the acceptance message. Terminal 500 ') and the socket for the file transfer is connected and the file is transmitted through the socket. In this case, the socket for file transfer is preferably a TCP / IP socket. This is to minimize the loss of data during file transfer.

The PDSN interface unit 140 performs data communication with the PDSN ('400' of FIG. 2). For example, data communication is performed with mobile communication terminals (eg, client terminals 500 and 600) registered in a buddy list (aka, contact list) of the host computer 100 and using a mobile messenger service. . In particular, the PDSN interface unit 140 transfers the loaded file to another mobile communication terminal (for example, 'client terminal 500' of FIG. 3) in response to the transmission request. And receives a file transmitted from one of the other mobile communication terminals using the mobile messenger service.

The storage unit 150 stores information related to the operation of the host terminal 100 (eg, a driving program for controlling system driving, data related to the program, and the like). In particular, the storage unit 150 preferably stores the address book 151, the messenger program 153, and the buddy list 155. At this time, the 'buddy list 155' is a list (also known as a contact list) for users who want to conduct a conversation through the mobile messenger service.

In addition, the host terminal 100 further includes a display unit (not shown) for displaying an operation state of the host terminal 100 under the control of the controller 130, and the controller 130 is a file transfer progress situation during file transfer. After the identification of the file transfer progress is preferably displayed on the display unit (not shown). In addition, the control unit 130 receives the transmission result from the other mobile communication terminal receiving the file after the end of the file transfer, and preferably displays the result on the display (not shown).
