System, mobile terminal, and method of controlling and supporting terminal to control host memory

Abstract

Some embodiments of the invention relate to the technical field of data processing, and disclose a system, a mobile terminal and a method for controlling and supporting a terminal to control a host memory. The method for controlling the host memory provided by the embodiment of the invention is applied to the mobile terminal connected with the host through the USB interface; both the host and themobile terminal follow a pre-designed communication protocol; the method for controlling the host memory comprises the following steps: receiving an operation requirement query of file data in the memory periodically sent by a host, and detecting whether an operation instruction of a user on the file data is received or not; if an operation instruction of the file data is received, inquiring and sending service request information to the host based on the communication protocol according to the operation instruction and the operation requirement; and receiving a response result fed back by thehost based on the communication protocol according to the service request information for responding to the operation instruction. According to part of embodiments of the invention, the mobile terminal can control the memory on the host, so that the space transmission time occupied by the to-be-operated big file data is saved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a system, a mobile terminal, and a method for controlling and supporting a terminal to control a host memory. Background technique [0002] Terminals such as mobile phones and computers are widely used in people's daily life, and users can perform operations such as reading and writing file data in the mobile phone memory on the mobile phone. However, the inventor has found that at least the following problems exist in the prior art: when the user wants to operate the file data that takes up a lot of space and is only temporarily used by the mobile phone, the file data will be downloaded to the mobile phone (such as from a mobile phone connected to the mobile phone). host computer, or download directly from the mobile phone over the Internet), but it takes a long time to transfer the file data, and the file data takes up a large amount of mob...

Problems solved by technology

However, the inventor has found that at least the following problems exist in the prior art: when the user wants to operate the file data that takes up a lot of space and is only temporarily used by the mobile phone, the file data will be downloaded to the mobile phone (such as from a mobile phone connected to the mobile phone). host computer, or download directly from the mobile phone over the Internet), but it takes a long time to transfer the file data, and the file data takes up a large amount of mobile phone storage space

In addition, when the occupied space of the file data is larger than the maximum space of the mobile phone memory, the mobile phone will face the problem that the file data cannot be operated
