The present invention relates to a mobile communication terminal equipped with a high-speed data transmission module that enables real-time data transmission between the mobile communication terminal and the PC, in particular, all functions without interruption of calls, texts, alarms, etc. of the mobile communication terminal during data transmission. High speed data that operates on DS Task to process large data at high speed and processes data by packet method, and inputs and outputs data between terminals and PCs in file unit in the same way as the data transmission method used in general PCs. A mobile communication terminal having a built-in transmission module and a high speed data transmission method using the terminal are provided.

In general, a mobile communication terminal has functions such as a call, a text message, an alarm, and a data communication (AT command), and controls each function through a communication module to perform each communication function. .

The data communication uses an AT command communication method (string communication method) or DM (Diagnostic Monitoring) mode communication method.

The AT command used in the AT command communication method is a command made for a modem rather than a mobile communication terminal, and supports a function of an existing modem such as FAX or PPP. Legacy Modem (Haze Modem) The terminal using the AT command is capable of data communication while using all functions (Call, SMS, etc.) as it is, but this command method has a problem that the communication speed is significantly slow because it is processed in units of one byte. . In addition, it does not support the processing of bulk data (MP3, image, video, etc.), not character data, so data processing is required to be processed separately in order to process the data, so the data transmission speed of the terminal is significantly increased. There was also a problem of deterioration. Therefore, the AT command communication method as described above is mainly used for transmitting schedule management (PIMS) information such as a phone book and a schedule and a small amount of image data.

Next, the DM mode communication method uses a DM (Diagnostic Monitoring) mode having a function of monitoring and controlling various modules of the terminal, and uses a DM task module having this function mounted on the terminal. In addition, since the DM task module mainly performs processing related to the performance or functions of the terminal in addition to the above functions, in order to operate this mode, all the functions of the terminal must be switched to a suspended state, which is called DM mode.

The use of the DM mode as a method for data communication between the mobile communication terminal and the PC is to solve the problems of the AT command communication method and the problem of low communication speed.

However, since the DM mode communication method stops all functions of the terminal and uses only necessary functions, there is a problem that the terminal must be rebooted after ending the function.

In addition, the data transmission speed is faster than the AT command communication method because the data is transmitted in the packet method rather than the character string processing method, but there is a problem that it is slow to transmit a large amount of data at a high speed. There is a problem that it can not process other than the basic command that is low scalability.

The mobile communication terminal configured as described above stops the operation of the SMS module and the call module of the mobile communication terminal in order to exchange data with the PC in the DM mode communication method, and blocks the call and the number / outgoing call of the DM task module. Data communication with a PC was performed by packet transmission. Therefore, during the data communication, there is a problem in that the mobile communication terminal does not make / receive / outgo a phone call and SMS, and there is a problem that the terminal must be rebooted in order to use other functions of the terminal after data communication is completed.

In addition, the USB driver used in the current mobile communication terminal uses an ACM model of the USB CDC class, and uses a method of transmitting data to a USB device using a COM port. Therefore, the speed is lowered in the process of using a USB device, there is a problem in processing high-speed large data I / O, and rebooting to return the mobile communication terminal to the normal state after the large-capacity communication using the driver of the ACM model. There was a problem that must be.

Accordingly, an object of the present invention is to enable high-speed mass data communication with a PC while using all the functions of a mobile communication terminal in order to solve the problems of the AT command communication method and the DM mode communication method.

In addition, it is possible to improve the data transfer speed and to make it easy to apply to various applications by inputting and outputting data in file units in the same way as the method used in a PC without using a method of matching / gathering using a separate engine. Another purpose.

In order to achieve the above object, the present invention provides a mobile communication terminal including a call module for a telephone call, an SMS module for text / calling, a data communication module for data transmission, and a USB device for data communication with a PC.
