Updating method for synchronization between customer terminal and server

Abstract

The invention discloses a method for updating a client and a server synchronously, which comprises the following steps: generating a static file from a dynamic file by the server and storing the static file in a static catalog; making an initial backup for the static catalog of the server by the client; regenerating the static file from the modified dynamic file when the server performs periodical check on a source catalog storing the dynamic file, storing the static file in the static catalog, and modifying the version number of the static file simultaneously; sending a static file list stored in the client to the server when the client is updated; comparing the received static file list with the static file list stored in the server by the server, and putting the static file lists with different versions to a temporary catalog; sending all the files in the temporary catalog to the client by the server; and updating the client according to the received files. Therefore, by adopting the technical proposal of the invention, the downloading stream quantity in the updating of the client can be reduced so that the downloading stream quantity is minimized.

Description

technical field [0001] The invention relates to the wireless application field, including the wireless network application technology of a server and a client, in particular to an updating method for synchronizing the client and the server. Background technique [0002] With the advent of the network era and the increasingly widespread application of client devices, the application of wireless network technology has gradually penetrated into people's daily life, work and study. Typically, a wireless network includes servers and clients. In most applications, in order to provide better services, the information on the client needs to be consistent with the information on the server. That is, the files stored on the client must be up to date. [0003] In order to maintain the data consistency between the client and the server, most of the update methods for the client are currently based on the package, that is, all the files that need to be updated are packaged, and then se...

Problems solved by technology

[0004]Because the server packs the package in advance and distributes it, the content of the package sent to each client is the same. For those clients who only want to update one or two files in the package , it is also necessary to download the entire upgrade package before it can be updated, which makes the amount of transmitted data large, resulting in unnecessary download traffic
