Method for maintaining PIM data consistency

An information management and consistency technology, applied in network data management, wireless communication, communication supplementary services, etc., can solve the problem that the server-side data cannot be downloaded to the client-side, the server-side and client-side data are inconsistent, and it is not easy for end users to understand. and selection, to avoid data loss, promote application prospects, and be easy to master.

Problems solved by technology

[0011] Using the above-mentioned existing synchronization methods, data synchronization between the server and the client can be realized, but each has its own shortcomings, especially the four types of client-side fast synchronization, client-side refresh synchronization, server-side fast synchronization and server-side refresh synchronization. The method is one-way synchronization, which may easily cause data inconsistency between the server and the client, and these concepts are not easy to be understood and selected by end users
Although fast synchronization and slow synchronization can realize two-way synchronization between the server and the client, user data is often lost due to user misoperation or misunderstanding of synchronization. The relevant data of the client is synchronized, the original intention of the operation is to delete all the data on the client, and then synchronize from the server; however, the actual effect is: if the data on the client is deleted and synchronized with the data on the server, The data on the server side will also be deleted, and the purpose of downloading the data from the server side to the client cannot be achieved.
Moreover, so far, the various existing communication protocols have not made corresponding regulations or definitions on how to effectively maintain the consistency of PIM data in the process of data synchronization

Embodiment Construction

[0060] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0061] see figure 1 , introduce the flow chart of the operating steps of the method for maintaining PIM data consistency in the present invention:

[0062] Step 1. Initialization settings: the user first selects and sets the synchronization method of personal information management data on the configuration file interface of the client. This step includes the following operations:

[0063] (11) The system displays the following three default synchronization methods on the configuration file interface of the client for users to choose and configure (see figure 2 shown):

[0064] PUT synchronization, put the client data on the server side, that is, overwrite the server side with the client data;

[0065] GET synchronization, put the server-side data on the clie...

Abstract

A method of maintaining consistency personal information management data comprises the steps of: (1)the user selecting synchronization mode setting PIM data on configuration files interface of the client; (2) the system executing the corresponding synchronous operation according to the synchronization mode set by the user; before the synchronous operation, the system backing storing the to-be-deleted client data or server data to transfer in the following operation; (3) when the user obliterates data because of error operation, selecting to execute the data rollback mechanism step to select the appropriate synchronization mode to synchronize again after restoring the original data. The invention utilizes slow sync of SyncML to realize two synchronization modes of PUT and GET; such that the user can conveniently select whether to synchronize by taking the server as standard or taking the client as standard, and provides operation steps of deleting the secondary confirmation of data and establishing the recycle bin of deleting data, and can effectively maintain the consistency of the data at two sides of the client and server.

Description

technical field [0001] The invention relates to a new service of mobile communication, more precisely, relates to a method for maintaining the consistency of personal information management data, and belongs to the technical field of telecommunication value-added services. Background technique [0002] Modern communication technology has greatly improved the breadth, frequency and convenience of information communication between people. Now, almost every user has stored a large amount of personal information on their mobile phones or other mobile terminals, including address book, text messages, ring tones, pictures, schedules, etc.; The average replacement cycle of Chinese users is 18 months), and the demand for information storage and backup is becoming more and more urgent. In addition, many mobile users (especially high-end users) have a strong need for communication. These users usually have a large number of address book information of relatives, friends and customers...
