Problems solved by technology

Due to the limitation of the storage capacity of the mobile device, when the mobile device is processing multimedia information that requires a large storage capacity, it encounters the difficulty of the limitation of the capacity of the storage medium of the mobile device, so that the mobile device cannot process multimedia data that requires a large storage capacity. cannot run multimedia applications on mobile devices
In the prior art, there is a technology that connects the remote server and the mobile device, so that the mobile device can use the storage resources on the server, but this technology requires the mobile device to be able to access the network, and the performance of the mobile device to use the storage capacity of the server affected by network bandwidth

Embodiment Construction

[0012] Referring to Figure 1, modern operating systems generally provide an abstract file system interface model, allowing developers to add their own specific file systems to the system, such as virtual file systems provided by multi-user operating systems and Windows operating systems Interface, which defines the interface for file opening, reading, writing and other operations.

[0013] In the present invention, the operating system provides a file system interface to the upper layer application. By rewriting the implementation of this interface, the original input and output request to the disk is sent to the remote machine through the network, thereby utilizing the storage on the remote machine. Implemented a virtual storage device.

[0014] Referring to Fig. 2, the present invention is realized on the windows CE (embedded windows operating system) platform. Generally, the user's application programs are faced with standard operating system application programming interf...

Abstract

The present invention is method of utilizing virtual equipment file system in expanding memory capacity of movable device, and aims at solving the problems of available movable equipment memory medium with small capacity and high cost. The method includes establishing one virtual equipment file system module in movable equipment and suspending in the operation system of the movable equipment; providing the application in the virtual equipment a virtual memory space via the virtual equipment file system module and sending the write / read request to the virtual memory space via network to remote end server; converting the write / read request in the remote end server into the write / read request to the local memory equipment in the server; and back transmitting the write / read result via the network to the movable equipment. It has the advantage of capacity of using the cheap great capacity memory space in server by the movable equipment.

Description

technical field [0001] The invention belongs to the technical field of interconnection or transmission request processing between computer network memories, in particular to a method for expanding the storage capacity of a mobile device by using a virtual device file system. Background technique [0002] With the advancement of computer technology and communication technology, mobile devices have increasingly stronger processing capabilities and access to the Internet in various ways at a very fast speed. Therefore, various mobile terminals are used more and more widely. It is no longer a distant dream to process various information on mobile devices such as personal digital assistants and mobile phones, such as watching movies and listening to music. [0003] Due to the size and portability requirements of mobile devices, most of the storage media used are flash memory cards, smart media cards, etc., and the storage capacity is mostly around tens of megabytes, and the price...
