Problems solved by technology

[0008] Second, once there is a problem with the network, such as temporary disconnection, and the transmission of some data information has been completed at this time, but not all transmission has been completed. In this case, all information has to be retransmitted, which takes up a lot of time. Internet resources

Embodiment Construction

[0059] The basic idea of ​​the present invention is that during synchronization, the user terminal only downloads the part of the difference between its own local data and the mail server data, rather than completely downloading, so as to realize the synchronization of differential data and effectively reduce the amount of synchronous data; at the same time, by converting the original data packet The transmission is carried out in blocks, so that when the network is interrupted, the entire original data packet is no longer retransmitted, but the data block that failed to be transmitted when the network is interrupted continues to be transmitted. It will take up a lot of network resources.

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only some, not all, embodiments of t...

Abstract

The invention provides a method for realizing the data synchronization of a mobile terminal PIM business, including receiving a request on data information synchronization sent by the mobile terminal; by comparing all data information records with the corresponding data information records of the mobile terminal, the difference between the data information preserved locally and the data information preserved by the mobile terminal is confirmed and returned to the mobile terminal. The invention also provides a mail server, a mobile terminal and a system. By the application of the method, the device and the system of the invention and the comparison of the difference of data synchronization, the quantity of data of synchronization is effectively reduced; and at the same time, through transmission resuming at break-points, the synchronized communications volume is decreased and a large amount of network resources is saved; and by different encodes and compression methods, the effective load coefficient of data is improved and the data traffic is reduced.

Description

technical field [0001] The present invention relates to the field of mobile terminal Internet technologies, and in particular to a method, device and system for realizing data synchronization in a mobile terminal PIM service. Background technique [0002] With the rapid development of mobile terminal Internet technology, PIM (Personal information Management, personal information management) technology has begun to be widely applied to mobile terminal Internet services. PIM is a service based on any platform (WWW, WAP, SMS) for personalized data information management of end users. Its core is the organization and management of data information. The data information of a class of people and things can be served by a certain person, a certain enterprise or even a certain industry. The PIM applied to mobile terminal interconnection services enables people to use mobile terminals to access Internet services and manage their own time, plans and data information fully and efficie...
