Description

Data synchronization method, device and system

The present application claims priority to Chinese Patent Application No. 201310147019.4, entitled "A Data Synchronization Method, Apparatus and System", filed on April 24, 2013, the entire contents of which is incorporated herein by reference. In the application. The present invention relates to the field of communication information technologies, and in particular, to a data synchronization method, apparatus, and system. Background technique

At present, the identification of which data needs to participate in synchronization, the use of log management, and the operation of the same data does not have a merge function, which will lead to many unnecessary operations, resulting in inefficient system data.

Specifically, for the client that needs to be synchronized, most of them are mobile phones, and the processing power of the mobile phone, whether it is mobile phone memory or mobile phone 10, is relatively general, if such a log is combined according to the function of not combining the operations of the same data. Management mode, each operation records the corresponding log management, which will cause a relatively large burden on the client's system. The user's mobile phone runs slowly, the power consumption is large, the response is slow, and it is difficult for users to accept. At the same time, due to the client record Each operation is eventually synchronized to the server (the server is the same), which undoubtedly increases the load on the server operation and processing, and therefore prolongs the entire synchronization process. This can lead to a higher risk of synchronization failure for a mobile Internet.

Further, the mobile Internet network is complex and variable, and is also subject to traffic restrictions. If there is an increase in unnecessary operations, then there will be a lot of redundant data in the final data packet, which will inevitably lead to a larger data packet and consume the user's valuable mobile phone traffic. On the other hand, if the scheme of merging logs is well optimized, it cannot avoid a problem. Essentially, the client is required to capture data operations and complete log records. For example, if the user modifies an address book on the mobile phone, then it is required to generate a log matching the synchronization requirement on the mobile phone. And it is clear that the address book belongs to the mobile phone system, and does not belong to the client of the synchronization system. Therefore, when the user modifies an address book on the mobile phone, the mobile phone does not generate a log that meets the synchronization requirements. Without logs, log management and log consolidation are impossible to talk about. Because, if the sync client wants to synchronize data that is not part of the sync client itself, the sync client will not be able to log management and log merge, lacking flexibility and operability.

The system solves the problem that the synchronization client can accurately find out the data that needs to participate in synchronization without the data operation log, and has the advantages of quickness, real time, high efficiency and applicability.

As shown in FIG. 4, a specific flowchart for implementing the data synchronization method.

Step S401 is to initiate a data synchronization request. Initiating the data synchronization request may be triggered by the user's operation, or may be automatically initiated by the mobile terminal 301 or the server 302 periodically according to a predetermined time period. Step S402 acquires the first data to be synchronized for the obtaining unit 201. The first data is obtained locally from the mobile terminal 301.

Step S403 is to determine whether there is different data information in the first data and the second data based on the data number and the data feature information; if the data number and the data feature information are included in one of the first data and the second data At least one of the first data and the other information in the other data of the first data and the second data are different, and it is determined that the first data and the second data have different data information.

In an embodiment of the present invention, the data structure of the data information in the first data and the third data includes at least a data number, data content, and data feature information, and the second data is based on the last data synchronization process. The data structure of the data information in the second data generated by the obtained third data includes at least a data number and data feature information. In an embodiment of the invention, the data feature information is unique identification information determined based on at least one of data content, timestamp information, and data length information of the data message. The data feature information is calculated by calculating at least one of data content, time stamp information, and data length information of the data message according to a specific formula. In an embodiment of the present invention, the data information in the first data, the second data, and the third data may be a plurality of pieces or may be 0 pieces. Specifically, it is determined whether there is data information in the first data that is different from at least one of the included data number and the data feature information and any data information in the second data, and whether the presence or absence of the second data includes At least one of the data number and the data characteristic information is different from the data information of any of the first data.

Step S404: When the determined different data information is from the first data and the data number has no data in the second data, the server adds the data information corresponding to the data number to the corresponding data stored by the server. In step S405, when the determined different data information is from the first data, and the data information having the same data number but different data feature information exists in the second data, the data corresponding to the data number in the first data is used. The information replaces the data information having the same data number in the corresponding data stored by the server.

Step S406: If the determined different data information is from the second data and the data number that is included does not exist in the first data, the data information corresponding to the data number is deleted from the corresponding data stored by the server.

Step S407: The server 302 returns the third data after the synchronization processing to the mobile terminal 301.

Step S408: The mobile terminal 301 synchronizes the first data according to the returned third data. Step S409 is to generate second data according to the data number of the first data after synchronization and the data feature information. Specifically, the mobile terminal stores the data number and the data feature information of the first data after the synchronization is completed as the second data, so that when the first data is synchronized next time, the data needs to be synchronized according to the second data. Data information.

Further, a process of identifying data that needs to be synchronized is described by taking a synchronous android system mobile phone address book as an example. The data in the mobile phone address book is the first data, and each address book data has a unique data number DATAID in the android system mobile phone address book, and the data content DATE and the data feature information FP. Example 1:

Assume that data synchronization has never been done before, and the second data is empty. The data structure of this first data:

The data structure of the second data:

The synchronous data identification process is as follows:

At this time, the data number DATAID and the data feature information FP are searched and checked one by one in the first data and the second data, and it is found that data of dataid=l or dataid=2 or dataid=3 cannot be found in the second data. It can be concluded that the three data of dataid=l, dataid=2 and dataid=3 in the mobile phone address book must participate in synchronization, and the data synchronization device of the mobile phone sends the three pieces of data information to the server, and the server stores in the server. The three pieces of data information are added to the corresponding data to obtain the third data. The server returns the third data to the mobile terminal, and the mobile terminal updates the first data according to the third data to effect data synchronization. The first data is synchronized with the third data. The mobile terminal stores the data number and data feature information of the first data after the synchronization is completed as the second data. Example 2:

Assume that the mobile terminal has previously performed data synchronization. At this time, the data structure of the first data:

DATAID DATA FP

1 139139 2zvgSnlk6PBY37zTH94yy0EX

2 138139 3Bd5ii3ALxz0sPHQw3De58I 4 133131 3r20wR4sxrpgl iXk4Q2z5eEI

5 0201234567 v9kB64o04GmhuFWvl4JqCL The data structure of the second data:

The synchronous data identification process is as follows:

The data information with the data number of dataid=l in the first data can be found in the second data, and the data of dataid=l in the first data is the same as the data characteristic information of the data of dataid=l in the second data, FP=2zvgSnlk6PBY37zTH94yy0EX, so this data information does not need to participate in data synchronization. The data information of the data number dataid=2 can be found in both the first data and the second data, but the data feature information of the two data is inconsistent, and the data information corresponding to the data information of dataid=2 in the first data corresponds to the dataid of the second data in the second data. The data information of =2 corresponds to fp=lcAYTS3rtsPy3 AnXGlA26Zl, so this data is to participate in synchronization, and the server replaces the data information having the same data number in the corresponding data stored in the server by using the data information of dataid=2 in the first data.

The data information in the second data whose data number is dataid=3 is not found in the first data, and the data information of dataid=3, which is consistent with the data number thereof, is to be synchronized, and the server stores the corresponding information in the server. This data information is deleted from the data.

The data information whose data number is dataid=4 in the first data cannot be found in the second data, so the data information is to participate in synchronization, and the server adds the data information to the corresponding data stored in the server.

Similarly, the data information whose data number is dataid=5 in the first data cannot be found in the second data, so the data information is to participate in synchronization, and the server adds the data information to the corresponding data stored in the server.

At this time, the server obtains the third data, and the server returns the third data to the mobile terminal, and the mobile terminal updates the first data according to the third data to implement data synchronization. The first data is synchronized with the third data. The mobile terminal stores the data number and data feature information of the first data after the synchronization is completed as the second data.

The data synchronization method of the embodiment of the present invention, based on the data number and the data feature information, obtains the current requirement Synchronized data, complete synchronization of local and server data. The method solves the problem that the synchronization client can accurately find the data that needs to participate in synchronization without the data operation log, and has the advantages of quickness, real-time, high efficiency and applicability.
