A transmission unit for additionally transmitting; It is achieved by a messenger server.

Details of the above object and technical configuration of the present invention and the resulting effects thereof will be more clearly understood from the following detailed description based on the accompanying drawings.

First, FIG. 1 to FIG. 5 are conceptual views illustrating a method of simultaneously transmitting and receiving a file and a message of the present invention. FIGS. 1 and 2 illustrate an example of a case where a mobile communication terminal transmits a file. Illustrates an embodiment of a case where a mobile communication terminal receives a file.

The present invention divides a large file into several unit files and transmits a chat message that is input in the middle. As shown in FIGS. 1 and 2, the mobile communication terminal of the present invention transmits a file to be transmitted at a constant size. The file is divided into unit files and transmitted sequentially.

For example, if the size of a photo file to be transmitted is 100Kbyte, the 100Kbyte photo is not transmitted at once, but divided into 50 unit files having a size of 2Kbyte.

As such, if a chat message is input from the user and the transmission is requested during the division into unit files and transmitted one by one, the mobile communication terminal of the present invention sends the chat message to the messenger server before transmitting the next unit file as shown in FIG. 1. As shown in FIG. 2, a chat message is included in the next unit file to be transmitted.

In this case, it should be distinguished by the messenger server or the receiving mobile terminal that the chat message is included in the unit file, and a flag indicating whether or not the chat message is included may be used for this purpose.

For example, a unit file not including a chat message is transmitted by setting a flag indicating the presence or absence of a chat message to "0". In the case of a unit file including a chat message, the flag is changed to "1" while the unit file containing the chat message is changed. A method of adding the length and the message content to the unit file may be used.

On the other hand, in a general case, the messenger server should transmit the received file to the other party's mobile communication terminal again. Even in this case, when the messenger server transmits a large file at a time, the receiving mobile communication terminal sends a chat message. You will not be able to send or receive.

Therefore, the messenger server does not merge the received files in the unit file form into one again, but transmits them to the receiving mobile terminal as it is in the unit file form as shown in FIGS. 3 to 5. Even if a file is not received, the messenger server may divide the file and send it by itself.

As shown in FIG. 3, the messenger server transmits a unit file received from a transmitting mobile terminal or a unit file generated by a messenger server to a receiving mobile terminal.

At this time, if a chat message transmission to the receiving mobile communication terminal is requested from a transmitting mobile terminal or another mobile communication terminal that has transmitted a unit file, the messenger server transmits the chatting message to the receiving mobile communication terminal. The receiving mobile terminal can receive and output a chat message while receiving a file.

4 and 5 illustrate an example in which a chat message is included in a unit file transmitted from a transmitting mobile terminal.

Even if a chat message is included in the unit file, the messenger server may transfer the unit file received from the sender mobile terminal as it is, as shown in FIG. 4. In this case, the receiving side mobile communication terminal recognizes that the received unit file includes a chat message, extracts the chat message from the unit file, outputs it, and then continues receiving the next unit file.

Meanwhile, in FIG. 4, the unit file transmitted by the messenger server to the mobile communication terminal may not be received from the sender mobile communication terminal, but may be a file directly generated by the messenger server, and the messenger server may be transmitted to the receiver mobile communication terminal. If there is a chat message, the chat message is added to the unit file and sent. This allows the receiving mobile communication terminal to transmit and receive a chat message while receiving a file even when the transmitting mobile communication terminal does not divide and transmit the unit file.

5 illustrates an embodiment in which a messenger server that receives a unit file including a chat message from a transmitting mobile terminal transmits a unit file and a chat message to a receiving mobile terminal.

As shown, the messenger server monitors the unit files received from the sender mobile communication terminal, and if a chat message is included in a specific unit file, extracts a chat message from the unit file and transmits it to the receiver mobile communication terminal. The unit file except for the chat message can be transmitted in the following order.

This may be used when the mobile communication terminal cannot recognize a unit file including a chat message by itself or when it is not easy to extract a chat message from the unit file.

Next, FIG. 6 is a configuration diagram of a mobile communication terminal according to an embodiment of the present invention, and FIG. 7 is a configuration diagram of a file transmission / reception module of FIG. 6. Referring to Figures 6 and 7, the configuration of a mobile communication terminal according to the present invention will be described.

As shown, the mobile communication terminal 100 includes a wireless transceiver 110 for transmitting and receiving wireless signals with a base station, an input unit 120 for outputting corresponding data according to a user's input, and a memory for storing various data. 130, a display unit 140 for receiving and displaying key data and various information signals generated from the input unit 120, and an audio unit 150 for processing voice signals input and output through a speaker and a microphone. And an instant messenger module 160 for instant messaging services and a file transceiving module 170 for implementation of the present invention.

The instant messenger module 160 is installed in a terminal to provide a chat service and a file transmission / reception service between mobile communication terminals.

The file transmission / reception module 170 is a module supporting simultaneous transmission of a file and a chat message. When a specific file is requested to be transmitted through an instant messenger, the file transmission / reception module 170 divides the corresponding file into unit files and transmits the data between the unit sections. It is possible to send and receive a chat message, and when a unit file is received, the unit file is merged to generate one completed file.

The instant messenger module 160 and the file transceiving module 170 should interoperate with each other. When the user requests a file transfer, the instant messenger module 160 transmits the corresponding file transfer request information to the file transceiving module 170. The file transmission and reception module 170 is driven.

In this case, when the chat message transmission event occurs in the middle of the transmission of the unit file, the file transmission / reception module 170 transmits the message first and then transmits the next unit file, or includes a chat message in the unit file to transmit the instant message. When the messenger module 160 is requested to transmit a chat message while the file transmit / receive module 170 is driven, the messenger module 160 should transmit the chat message to the file transmit / receive module 170. In this case, the file transmission / reception module 170 transmits a file transmission completion signal to the instant messenger module 160 when the transmission of all the unit files is completed, and then ends the driving.

Meanwhile, in the present embodiment, the file transmission / reception module 170 and the instant messenger module 160 are separated, but the file transmission / reception module 170 supports the file transmission / reception function and the chat message transmission / reception function of the instant messenger module 160. Therefore, it may be included in the instant messenger module 160.

The configuration and function of the file transceiving module 170 will be described in more detail with reference to FIG. 7 as follows.

As illustrated in FIG. 7, the file transmission / reception module 170 includes a file division unit 171, a first unit file storage unit 172, and a transmission unit 173 as a configuration for file transmission. The configuration for the receiver includes a receiving unit 174, a second unit file storage unit 175, a file merging unit 176.

The file division unit 171 generates N unit files by dividing the corresponding file into unit files having a predetermined size when a request for transmission of a specific file is requested from the user through a messenger, and then generates the unit files, and then stores the first unit file 172. Store in In this case, the file division unit 171 may generate a unit file by including a flag field indicating whether or not the chat message is included in the unit file.

The transmission unit 173 sequentially transmits N unit files stored in the first unit file storage unit 172, but if there is a chat message currently requested to be transmitted before each unit file is transmitted, the corresponding chat message is transmitted. After that, the unit file is transmitted or the chat message is added to the current unit file.

In order to add a chat message to the unit file, the transmitter 173 adds the length information of the chat message, flag information indicating whether the message is included and whether the chat message is included in the unit file to be transmitted, and the flag as described above. Instead of adding information, you can change the flag information of the original unit file.

When the receiving unit 174 sequentially receives N unit files in which a specific file is divided into a predetermined size from the messenger server, the receiving unit 174 stores each unit file in the second unit file storage unit 175, and the messenger server during each unit file reception. When a chat message is received, the corresponding chat message is output and the next unit file is received.

According to another embodiment, when the receiver 174 receives a unit file including a chat message, the receiver 174 should extract and output a chat message from the corresponding unit file, and output the unit file except for the chat message. The second unit file storage unit 175 is stored.

If the instant messenger module 160 performs a function of outputting a chat message, the receiver 174 may transfer the extracted chat message to the instant messenger module 160.

When all the N unit files are received, the file merging unit 176 merges the N unit files stored in the second unit file storage unit 175, restores the original unit file, and stores the unit file in the memory 130.

Meanwhile, among the roles of the mobile communication terminal 100 described above, a role related to file transmission, that is, a function of dividing and transmitting a file into a unit file and transmitting a chat message in the middle or adding a chat message to the unit file is performed. The same applies to the messenger server of the present invention.

Therefore, the configuration of the messenger server is not separately illustrated in the drawing, and the file division unit 171, the first unit file storage unit 172, and the transfer unit 173 of the file transmission / reception module 170 are messenger servers. It will be described as a configuration of.

The file division unit 171 of the messenger server divides a file to be transmitted to a specific mobile communication terminal into unit files having a predetermined size, thereby generating N unit files and storing the N unit files in the first unit file storage unit 172.

The transmission unit 173 sequentially transmits N unit files stored in the first unit file storage unit 172 to the mobile communication terminal 100, but before transmitting each unit file, the current mobile communication terminal ( If there is a chat message requested to be transmitted to 100), the unit file is transmitted after the chat message is transmitted, or the chat message is added to the unit file to be transmitted.

Meanwhile, when a file is transmitted in a unit file form from a mobile communication terminal, the messenger server can directly transmit the received file to the receiving side mobile communication terminal without dividing the file separately. Only the operation of the transmission unit 173 is required without the operation.

Next, a method of simultaneously transmitting and receiving a file and a message of the present invention will be described with reference to FIGS. 8 and 9 as follows. 8 and 9 may also be interpreted as an operation process in the mobile communication terminal 100, or may be interpreted as an operation process in the messenger server.

First, FIG. 8 is a flowchart sequentially illustrating a file and message simultaneous transmission method according to an embodiment of the present invention.

As shown, if a file transfer is requested from the mobile communication terminal 100 to the messenger server or from the messenger server to the mobile communication terminal 100 (S801), the file dividing unit 171 stores the file with a predetermined size N. As shown in FIG. The file is divided into two unit files (S803).

Next, before transmitting the unit file, the transmitting unit 173 determines whether a chat message requested to be transmitted exists (S805), and if there is a chat message to be transmitted as a result of the determination, transmits the corresponding chat message first, or the unit file to be currently transmitted. After the corresponding chat message is added (S807), the unit file is transmitted (S809).

The above process is repeated until all the unit files are transmitted, that is, until the number of transferred unit files becomes N (S811). When all the unit files are transmitted, the file transfer is completed (S813).

9 is a flowchart sequentially illustrating a method of simultaneously receiving a file and a message according to an embodiment of the present invention. When unit files and chat messages are respectively received, processes are performed in the order in which they are received. 9 only illustrates an example in which a chat message is included in a unit file.

As illustrated, when the unit file is received (S901), the receiver 174 of the mobile communication terminal 100 or the messenger server determines whether a chat message is included using a flag of the unit file (S903). ). As a result of the determination, when it is confirmed that the chat message is included in the currently received unit file, the receiver 174 refers to the message length information of the unit file and extracts and outputs a chat message from the unit file (S905).

At this time, the receiving unit 174 stores only the original unit file excluding chat message contents and message length information.

The process is repeated until all unit files are received (S907). When all unit files are received, the file merging unit 176 merges the received N unit files (S909).

As those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features, the embodiments described above should be understood as illustrative and not restrictive in all aspects. Should be. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

Therefore, according to the method for simultaneously transmitting and receiving a file and a message of the present invention, and a mobile communication terminal and a messenger server therefor, a file transmission and a chat message transmission and reception using an instant messenger can be simultaneously performed in a terminal that can open only one socket. In addition, it is possible to increase the messenger utilization rate and data utilization rate by enabling real-time communication even during file transmission and reception.
