Abstract

The method comprises: when the files in the computer is transmitted to the mobile terminal, in the first, an initialization is executed; selecting a source file to be transmitted to the computer; the communication thread of computer uses signal mechanism to make real-time task communication with the mobile terminal; creating a target file used for writing data in, and opening the target file; the communication thread reads data from source file and packaging it into the writing file signals, and then packages the signals into the data frame in link layer, and sends the data frame to the mobile terminal through serial port; after confirming that the data is successfully written in, the remaining data is transmitted out using same way; after completing the transmission, the computer informs the file system of the mobile terminal to close the target file and to release the serial port and each relevant thread.

Description

technical field [0001] The invention relates to a data file transmission method, in particular to a data file transmission method between a computer (PC) and a mobile terminal. Background technique [0002] As one of the most dynamic telecommunication terminal products, the functions of mobile terminals are becoming increasingly fashionable. Following the color screen and camera mobile terminals, music mobile terminals have become another bright spot for mobile terminal manufacturers to seize the mobile terminal market, and camera functions have also been integrated into mobile terminals. At present, high-end music mobile terminals generally use an external memory card as a storage medium for music files, such as a T-FLASH card and the like. This method has outstanding advantages and is very convenient for storing data files, but due to increased hardware costs, it is bound to increase the price of mobile terminals. If the internal FLASH of the mobile terminal is used as t...
