Realizing method for mobile data synchronization middleware based on improved network protocol

Abstract

The invention provides a realizing method for mobile data synchronization middleware based on an improved network protocol. The method comprises the steps of adding a SlowTableLog object label into the SyncML head, taking the condition whether the attribute Last value of an object is empty or not as a condition for initiating slow synchronization, and determining to synchronize which data table according to a value of the Order attribute of the object; adding push-type synchronization into general synchronization to reduce unnecessary repeated uploading; adding fields of TableName and DevCode into a Map instruction to realize expression of mobile terminal and server terminal mapping information when a user carries out data synchronization on a plurality of sets of equipment and a plurality of data tables; adding an active push technology into mobile data synchronization realized based on the Sync ML protocol; combining pull-in synchronization and push-type synchronization, wherein the push-type synchronization is used for pushing synchronized messages, and the pull-in synchronization is used for synchronizing data from the server terminal.

Description

technical field [0001] The invention belongs to the field of computer science and technology, and relates to an improvement of a network protocol and a method for realizing middleware thereof. Background technique [0002] When using a mobile terminal device, it may often be in an environment where there is no network signal or the signal is very weak, so that it does not have the conditions to synchronize with the central database in real time, and if the mobile terminal is connected to the network in real time, its power consumption is very large. It will shorten the use time of mobile devices and reduce the user experience of mobile devices and applications. Therefore, the mobile database cannot be synchronized with the central database in real time. At the same time, the resources of mobile terminal devices are very limited, so the mobile database only stores user needs. It can be seen that mobile data synchronization is a kind of pseudo-data synchronization, which only ...

Problems solved by technology

Although the Sync ML protocol solves many problems in mobile data synchronization, it still has the following deficiencies: First, the data synchronization method stipulated in the Sync ML protocol. Slow synchronization may occur frequently, but the Sync ML protocol does not provide a strategy to avoid slow synchronization. In the process of large data transmission, if the network connection fails suddenly, the protocol will only synchronize data through slow synchronization when connecting to the network again, and cannot continue data transmission, causing a large amount of data to be repeatedly transmitted on the network, resulting in The waste of network traffic; the second is that the Sync ML protocol only realizes the pull-type mobile data synchronization, and does not realize the push-type mobile data synchronization actively pushed by the server, and cannot push the changed data to the relevant online mobile terminals in time;
