Problems solved by technology

In the current technology, the USB interface usually adopts a mass-storage transmission method to solve the problem of data transmission between the personal computer and the storage devices such as SD card and Nand flash memory in the mobile phone, and the data from the baseband is user-definable , the data format is completely different from the data from the storage device, and the baseband data transmission requires a stable bandwidth, and the communication between the personal computer and the baseband of the mobile phone cannot be completed through the USB interface.
In this way, many foreseeable flexible functions of the mobile phone cannot be realized by using the transmission capability of the USB interface.

Abstract

The invention discloses a virtual serial port device, which is connected between a baseband control device of a mobile communication device and a transmission drive device of a personal computer, and includes a baseband interface unit, a data storage unit, a controller and a physical interface unit; The data transmission between the baseband and the data storage unit is controlled by the baseband control device through the baseband interface unit; the controller is connected between the data storage unit and the physical interface unit, and processes and transmits data according to the USB protocol; the physical interface unit communicates with the transmission through the USB bus The drive transmits the data. The virtual serial device has high transmission bandwidth and versatility.

Description

technical field [0001] The invention relates to a virtual serial port device, in particular to a virtual serial port device between a baseband of a mobile communication device and a personal computer. Background technique [0002] In the existing application of handheld mobile communication equipment, the communication and data transmission between the baseband (BaseBand) and the personal computer (PC) are mostly completed through the infrared interface, and the bandwidth limitation is relatively large. With the increasing application of Universal Serial Bus (USB) interface in mobile phones, USB has become a main interface of handheld mobile communication equipment. In the current technology, the USB interface usually adopts a mass-storage transmission method to solve the problem of data transmission between the personal computer and the storage devices such as SD card and Nand flash memory in the mobile phone, and the data from the baseband is user-definable , The data for...
