Abstract
The present invention discloses a method for realizing a dynamic U disk function in a mobile telephone. A CPU of the mobile telephone is provided with a USB interface; residual space, which is formed by removing system information space in a Flash memory of the mobile telephone, is as memory space of the U disk, and thus, the function of the U disk is realized. The present invention uses hardware in the mobile telephone (the size from Wi to Fi) to realize the function of the U disk to make the mobile telephone and the U disk integration.
Description
Technical field
The present invention relates to a kind of method that in mobile phone, realizes dynamic U disc function.
Background technology
The developing rapidly and promoted developing rapidly of electronic information series products industry of science and technology, each electronic product and mobile communication equipment occur in a large number, and people require more and more higher to integrated, miniaturization, the mobility of product.Portable equipment and movable storage device produce under this background, and both in conjunction with also positive adaptation this trend and people's requirement.In conjunction with purpose be exactly in order to offer convenience to people, and make both functions bring out the best in each other.In today that informationization is popularized day by day, mobile phone and USB flash disk all are that people work, important information stores and delivery means in the studying and living.Wherein, the mobile phone popularization degree is higher, and the photo of surfing Internet with cell phone file in download and shooting is often used mobile phone EMS memory, and these files need transfer files to computer.USB flash disk is used for storage file, and volume is little, easy to carry, application popularization, but the USB flash disk volume is little, is easy to lose, if can be integrated in the function of USB flash disk in the mobile phone, will offer convenience to people.Mobile phone can be worked as USB flash disk usefulness on the one hand, and mobile phone can utilize the function of the feature richness of USB flash disk itself on the other hand.Particularly Wi-Fi (Wireless Fidlity wireless data network standard) mobile phone is as a kind of wideband mobile phone, and the function that adds USB flash disk is necessary.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method at mobile phone realization dynamic U disc function, utilizes the existing hardware of mobile phone to realize the USB flash disk function, makes mobile phone and USB flash disk integrated, prevents that the USB flash disk data from occupying the system documentation space and causing cell phone system to damage.
For solving the problems of the technologies described above, a kind of method of dynamic U disc function that realizes in mobile phone of the present invention is, the CPU of described mobile phone has USB (universal serial bus USB) interface, utilize the remaining space of removing the system documentation space in the Flash memory of this mobile phone, as the memory space of USB flash disk, thus the function of realization USB flash disk.
Use method of the present invention, mobile phone can be finished following function:
1, can pass through the direct and compunication of USB cable, carry out the storage of file or read the USB flash disk in people's notion that Here it is.
2, can exist in the USB flash disk that carries by the data of WLAN (wireless local area network WLAN (wireless local area network)) download or by the video camera picture shot, pass to computer, and then store or edit, handle via USB cable.
3, people were concerned about the size of USB flash disk often.In order to increase the memory space that mobile phone carries USB flash disk, prevent the USB flash disk data from occupying the system documentation space simultaneously and cause cell phone system to damage, its size detects Flash memory size of remaining space except that system documentation by system and is determined, because it is indefinite that system documentation takes up space, so the size of USB flash disk is dynamic.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the present invention is done explanation in further detail:
Fig. 1 uses method mobile phone of the present invention and computer connection diagram;
Fig. 2 uses method charging inlet expansion pin schematic diagram of the present invention;
Fig. 3 uses the big logotype in method dynamic U disc of the present invention space.
Embodiment
The method that in mobile phone, realizes dynamic U disc function of the present invention, the CPU of described mobile phone must provide USB interface, utilizes in the Flash memory of this mobile phone except that the shared space of system documentation, and remaining space is as memory space, thereby realizes the function of USB flash disk.
As shown in Figure 1, when mobile phone used as USB flash disk, mobile phone was linked on the computer by the USB cable line, and computer can be pointed out " finding new hardware ".From computer during reading of data, data are through cable, USB interface, and CPU deposits Flash; When mobile phone write data to computer, data were through Flash, CPU, and USB interface, cable is to computer.Communication therebetween must be followed the usb communication agreement.
USB interface can be utilized mobile phone charging interface expansion pin, needn't increase interface in addition, that is to say that data-interface and charging inlet unite two into one, and concrete condition can be in conjunction with shown in Figure 2.When inserting charging cable system can detect the pin charging and GND effective; When inserting USB cable system can detect pin USBD+ and USBD-effective.
The Wi-Fi mobile phone is a kind of wideband mobile phone, can realize surfing the Net fast and downloading from the Internet data, and these data can exist in the USB flash disk that mobile phone carries, and pass on the computer by the USB cable line again.Equally, the photo by video camera is taken also can pass on the computer via cable, makes amendment, beautifies by the image processing software comparison film on the computer, and is in addition perfect, makes like this to take the photo that comes and have value for preservation more.
Because the USB flash disk space is the remaining space of Flash except that system documentation, how to determine the USB flash disk size of mobile phone, prevent that the USB flash disk data from occupying the system documentation space and causing cell phone system to damage, be key of the present invention.Be example with 32M Flash below,, describe in conjunction with shown in Figure 3.System documentation fluctuates owing to frequent change causes institute to take up space, and increases " X " as end mark after system documentation, and the while increases " Y " as end mark after the USB flash disk data.Therefore the USB flash disk size equals 32M and deducts system documentation space (being X), and the USB flash disk remaining space equals 32M and deducts the shared space of USB flash disk data (being Y).CPU one powers on, and detects the remaining space of the size of USB flash disk and USB flash disk immediately and this information is sent in the mobile phone menu, uses for the user.
Claims (2)
1, a kind of method that in mobile phone, realizes dynamic U disc function, it is characterized in that: the CPU of described mobile phone has USB interface, in the Flash of this mobile phone memory, with removing the remaining space in system documentation space, as the memory space of USB flash disk; Increase " X " after the system documentation in described Flash memory as end mark, after the USB flash disk data, increase " Y " simultaneously as end mark; The memory space that the size of described USB flash disk equals the Flash memory deducts the system documentation space, the memory space that the remaining space of described USB flash disk equals the Flash memory deducts the shared space of USB flash disk data, CPU one powers on, detect the remaining space of the size of USB flash disk and USB flash disk immediately and this information is sent in the mobile phone menu, use for the user, thus the function of realization USB flash disk.
2, the method that in mobile phone, realizes dynamic U disc function as claimed in claim 1, it is characterized in that: USB interface utilizes mobile phone charging interface expansion pin to carry out the switching of data-interface and charging inlet, when inserting charging cable, system can detect the pin charging and GND effective; When inserting USB cable, system can detect pin USBD+ and USBD-effective.
