Problems solved by technology

[0005] In the existing technology, the method to solve this problem is mainly the synchronous cloud service access method. Although this method is more convenient, most of the existing cloud services do not fully consider the characteristics of the mobile client, and the amount of transmitted data is very large. Large, which brings large computing resource consumption and network bandwidth occupation to mobile devices, making its response not smooth and unable to access cloud services efficiently and conveniently

Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below.

[0037] see figure 1 , the data synchronization method applicable to multi-terminal devices in this embodiment includes the following steps:

[0038] (1) Identify the corresponding changed objects in the terminal equipment and mark them;

[0039] Specifically, change objects are divided according to business logic. Change objects are identified by global descriptor GUIDs, and relationships between change objects are associated by change object IDs.

[0040] (2) Write the marked change object to the local database;

[0041] The local database uses the Sqlite database.

[0042] (3) In the local database, retrieve the marked change object and stamp it with a time stamp, thereby abstracting it into a transaction log;

[0043] Specifically, a change of the setting change ...

Abstract

The present invention provides a data synchronization method on multiple devices. The method comprises the steps of identifying the change objects in a terminal device and marking; writing the marked change objects in a local database, stamping time stamps and abstracting into business logs; writing the business logs in a local synchronization table; using a terminal device background to read the business logs in the local synchronization table circularly, submitting and storing in a server end database; deleting the successfully submitted business logs from the local synchronization table; using a server end to read the business logs circularly, analyzing and reducing the business logs one by one; using other terminal devices to obtain the business logs from the server end; playing back the business logs in the local database; recording the current time stamps of the business logs; and noticing an upper-layer interface to update the data. The data synchronization method on the multiple devices of the present invention is suitable for the data synchronization of various mobile devices under an environment not having a network, supports the user edit, and then synchronizes the data to the background after the network is recovered. In addition, according to the present invention, the network utilization rate is improved, and the data access is more efficient and smooth.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a method for synchronizing data among various mobile terminal devices based on an off-network environment. technical background [0002] In the late 1990s, data synchronization began with wired connections, such as a MAC machine as a data center, and synchronized with a terminal device (iPod) through FireWire. After 2000, cloud services developed rapidly, and data centers represented by PC / MAC machines gradually turned to the cloud. As long as the device has a network, it can be used, such as address book, WeChat message backup and recovery, and App Store. [0003] In recent years, with the rapid development of Internet and chip technology, there are more and more types of mobile terminal equipment. Mobile terminal equipment refers to computer equipment that can be used on the move, such as mobile phones, notebooks, tablet computers, POS machines and eve...
