Description
Technical Field
The invention relates to the field of network downloading, in particular to a network downloading mechanism and a network downloading method based on data identification.
Background
Download (Download) refers to copying a file from an FTP server to its own computer. The FTP client software is used for accessing the independent FTP server, and a plurality of special FTP client software with different functions are available for selection. And the WWW server with embedded FTP can be accessed only by a browser. The browser is not only a WWW client program, but also has an embedded FTP function, and can be used as an FTP client program, and can download files from an FTP server or upload (upload) files to the FTP server.
An early method for downloading files from an FTP server was to directly access a known FTP server with FTP software (FTP. exe) and obtain the files with a set of specified commands, i.e. a command method, but this method is inconvenient and rarely used. At present, there are three main methods for downloading files from the Internet: (1) downloading directly from a webpage or an FTP site; (2) downloading the breakpoint resume software; (3) downloaded in the form of an email.
The direct downloading from a web page or an FTP site means that the downloading is carried out by using an FTP function embedded in a browser. The method is not only slow, but also afraid of abandoning the work due to the disconnection. Therefore, the breakpoint resume software is produced at the beginning, and is used for downloading files, even if a line is broken, the previously downloaded part is still effective, and only the breakpoint resume is needed to obtain the complete files, which is the most common downloading method for current users.

Detailed Description
Embodiments of the data identification-based network download mechanism and method of the present invention will be described in detail below.
4G LTE is a globally common standard including two network modes FDD and TDD, for paired and unpaired spectrum, respectively. The operator's initial trade-off between the two modes is purely for spectrum availability. Most operators will deploy both networks simultaneously in order to fully utilize all of their own spectrum resources. FDD and TDD are technically very small differences, the main difference being that different duplexing schemes are used, Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD) being two different duplexing schemes.
FDD receives and transmits on two separate symmetric frequency channels, with guard bands separating the receive and transmit channels. FDD must use paired frequencies, relying on frequency to distinguish between uplink and downlink, whose unidirectional resources are contiguous in time. FDD can make full use of the uplink and downlink spectrum when supporting symmetric services, but the spectrum utilization will be greatly reduced when supporting asymmetric services.
TDD separates the receive and transmit channels in time. In a TDD-type mobile communication system, different time slots using the same frequency carrier are used as bearers of a channel for reception and transmission, and resources in one direction are not continuous in time, and time resources are allocated in both directions. In a certain time period, the base station sends signals to the mobile station, in other time, the mobile station sends signals to the base station, and the base station and the mobile station have to cooperate to work smoothly.
