Embodiment Construction
[0029] In the embodiment of the present invention, the application processor enumerates the interfaces of the baseband processor; the application processor virtualizes the first interface connected to the second terminal into a serial interface; the application processor is connected to the interface with the baseband processor through the first interface The second interface forwards data between the baseband processor and the second terminal. Since the software update and / or parameter adjustment of the baseband processor can be performed through the dedicated interface of the application processor, the process of software update and / or parameter adjustment of the baseband processor in the smart phone is simplified.
[0030] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0031] like figure 2 As shown, the data transmission system according to the embodiment of the present invention includes...

The embodiment of the invention relates to the field of electronic technology, in particular to a method, a system and a device for data transmission, which are used for simplifying the process of software updating and / or parameter adjustment of a baseband processor in a smartphone. The method disclosed in the embodiment of the invention comprises the following steps: an application processor enumerates the ports of the baseband processor; the application processor virtualizes a first port connected with a second terminal into a serial port; and the application processor forwards data between the baseband processor and the second terminal through the first port and a second port connected with the port of the baseband processor. In the method disclosed in the invention, since the soft updating and / or parameter adjustment of the baseband processor can be realized through the special port of the application processor, the process of software updating and / or parameter adjustment of the baseband processor in the smartphone can be simplified, thereby being convenient for users and improving user experience.
Description
technical field [0001] The present invention relates to the field of electronic technology, in particular to a data transmission method, system and device. Background technique [0002] Smartphones are more complex than non-smartphones due to the many functions they support. Non-smart phones usually have a baseband processor responsible for radio frequency communication functions, user interface display, key and touch screen operations, etc. [0003] Since smart phones can provide users with more entertainment, video and other functions other than communication, smart phones have an application processor in addition to a baseband processor. Among them, the baseband processor in the smart phone is responsible for the functions of radio frequency communication; the application processor in the smart phone is responsible for functions such as user interface display and application program operation. Both the application processor and the baseband processor have their own soft...
