Movable communication device and electronic device

Abstract

The invention provides a movable communication device and an electronic device. The movable communication device comprises a file system, a first storage unit, a first file database, at least one first application program, a first USB interface, a first USB universal driving module and a first USB class X driving module; the first storage unit is used for storing at least one file; the file system is stored in the first storage unit; a first class X protocol layer lists the first information of the file and adds the first information to the first file database; the first USB class X driving module is coupled to the first class X protocol layer and the first USB universal driving module; the first USB class X driving module, the first USB universal driving module and the first USB interface are combined to form a data link. As a result, exchange visits of files can be realized between the movable communication device and the electronic device, and the synchronous operations or access of an external USB device also can be realized.

Description

technical field [0001] The invention relates to the field of data sharing, in particular to a mobile communication device and electronic equipment that realize mutual access through the universal serial bus technology. Background technique [0002] With the development of science and technology, the trend of mobile communication devices (such as mobile phones) as an intelligent terminal for personal information storage and management is becoming more and more obvious. We can not only use mobile phones to make and receive calls, but also use mobile phones to watch videos, read news, For storing personal data, conducting social networking activities, etc., mobile phones are increasingly becoming an indispensable personal information terminal. At the same time, personal computers (Personal Computers, PCs) have unique advantages in server data processing and entertainment functions. Therefore, for a long period of time in the future, mobile phones and PCs will jointly bear the m...

Problems solved by technology

[0003] At present, there are several ways to share files between mobile phones and PCs: 1. Using the Internet: For example, users can view chat records on mobile phones after logging in on PCs. The reverse process is also established. Furthermore, The network disk can also realize data sharing between mobile phones and PCs. These technologies are all based on the concept of cloud storage; 2. Use Universal Serial Bus (USB) to share files, mainly involving mass storage (Mass Storage) and There are two sharing methods of Media Transfer Protocol (MTP). Mass Storage needs to switch the storage device back and forth between the mobile phone and the PC. It cannot realize the mutual access between the mobile phone and the PC without changing the link. The operating system (Windows) of the mobile phone can access the database (Datebase) of the mobile phone to realize the management of the files of the mobile phone with the PC, but it is impossible to use the mobile phone to access the files of the PC at the same time; 3. Other communication methods, such as Bluetooth, high-definition multimedia interface ( High Definition Multimedia Interface, HDMI), FireWire (FireWire) interface, etc., but these communication methods are not as popular as Universal Serial Bus for PCs or mobile phones
