Problems solved by technology

In most cases, in SyncML DS / DM applications, the synchronization data still occupies most of the capacity of the entire SyncML transmission document. The current generated SyncML synchronization data packets are still relatively large, so there is potential for further compression

Embodiment Construction

[0040] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] The optimization method for data synchronization using a mobile data synchronization protocol of the present invention is used in a mobile communication network system including a client and a server, and the method includes:

[0042] In a synchronous initialization step, the client sends an initialization packet to the server, and the server sends a confirmation packet back to the client. Wherein, the initialization data packet sent by the client includes: synchronization mode, database type, client device capability, synchronization flag and authentication information, and also includes the compression algorithm flag and related compression configuration parameters used in the initialization step; The confirmation data packet returned by the server includes: authentication result, device capability and session establishment ...

Abstract

The invention discloses a method for carrying out data synchronization by using a mobile data synchronization protocol, which is used for a mobile communication network system including a client end and a server end. The method comprises the following steps: a synchronization initialization step: the client end sends an initialization data packet to the server end and the server end sends a confirming data packet back to the client end; a synchronization processing step: the client end sends the synchronization data as the synchronization compression data packet of the selected compression option structure to the server end; the server end decompresses and reduces the synchronization data packet and carries out the synchronization updating process according to the original SyncML protocol, then compresses and packs the synchronization data which composes the server end so as to send to the client end; the client end decompresses and reduces the returned synchronization compression data packet and carries out the synchronization updating process according to the original SyncML protocol; the processes are repeated until the synchronization data processing between the client end and the server end is finished.

Description

technical field [0001] The invention relates to a data synchronization method, in particular to a method for extending and optimizing using the data synchronization specification SyncML defined by the Open Mobile Alliance (OMA). Background technique [0002] The data synchronization specification SyncML defined by the Open Mobile Alliance (OMA) is a synchronization markup language and the only industry-wide mobile data synchronization protocol. The significance of SyncML is to change the current situation that mobile data synchronization is based on some different private protocols, and solve the problem that each private protocol can only support limited types of devices, systems and data types. The application of SyncML technology greatly simplifies the complexity of work in all aspects (users, manufacturers, service providers, developers). [0003] Many equipment terminal manufacturers have developed products with SyncML functions in the market. At present, the applicati...
