Description

A data synchronization method, terminal and system

technical field

The present invention relates to mobile communication technology, in particular to a data synchronization method, terminal and system.

Background technique

When users use services provided by different service providers, such as gmail service, hotmail service and China Mobile Caiyun service, the personal information corresponding to each service, such as Contact, Calendar, Task ), notes (Note) and e-mail (Email) are all managed by PIMS (Personal Information Manager, Personal Information Management System) to help users. And the personal information is stored in different servers according to different services, and at the same time, a copy of the personal information corresponding to the service is stored in the terminal. For example, for the three different services of gmail, hotmail, and China Mobile Caiyun, refer to Figure 1, which shows that in the prior art, the three services correspond to the storage form of personal information on the terminal and the communication with the server. A schematic diagram of the corresponding relationship.

In Figure 1, the personal information of the gmail service is stored in server 1, and the corresponding copy on the terminal is the local copy of S1. The personal information of the hotmail service is stored on server 2, and the corresponding copy on the terminal is the local copy of S2. The information is stored in server 3, and the corresponding copy on the terminal is the local copy of S3. Referring to Fig. 1, taking the address book information as an example, when the user uses the gmail service to send emails to the user to be communicated, if the communication information of the user to be communicated is not saved in the server 1, then the user uses the gmail service on the terminal When communicating with the user to be communicated, the information of the user to be communicated can only be manually entered into the local copy of S1 of the terminal; The user information to be communicated is sent to the server 1, so as to realize the information synchronization between the terminal and the server 1.

In this case, if the user uses the hotmail service to communicate with the user to be communicated at this time, if the communication information of the user to be communicated is not saved in the server 2, the user must enter the information of the user to be communicated again. to the local copy of S2 in said terminal. Therefore, users have the requirement to realize information synchronization in different servers, but in the prior art, three local copies are stored separately on the terminal, and each local copy has a synchronization protocol with a server alone to realize information Synchronize. For example, the local copy of S1 in the terminal only has a synchronization agreement with server 1, so it can only synchronize information with server 1, but cannot achieve information synchronization with server 2 and server 3, giving users personal information corresponding to different services caused inconvenience.

detailed description

In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Referring to FIG. 2 , it is a flow chart of Embodiment 1 of a data synchronization method provided by the present invention. This embodiment may specifically include:

Step 201: the current terminal configures local copies corresponding to multiple services as a local shared information copy.

In order to facilitate the description of the local shared information copy configured by the current terminal, as shown in FIG. All data for local replicas, S2 local replicas, and S3 local replicas.

Step 202: If the data of the local shared information copy in the current terminal is updated, the current terminal sends updates to the multiple servers corresponding to the multiple services according to the synchronization protocol between the multiple servers corresponding to the multiple services The first synchronization information of the data, so that the multiple servers perform data update according to the first synchronization information.

Preferably, the current terminal may send the first synchronization information carrying update information to multiple servers in the user's synchronization server set through a synchronization agent. The synchronization agent is a specific example of a synchronization protocol. As shown in FIG. 1, assuming that the current terminal and server 1, the current terminal and server 2 use the same synchronization protocol, the synchronization agent of the current terminal and server 1, the current terminal and server 1 The synchronization agent of server 2 executes the same protocol and the same communication process, but the synchronization target server is different.

Referring to FIG. 3 , it is a schematic structural diagram of a current terminal configured with a local copy of shared information. The other local copies shown in FIG. 3 are similar to the local copy shown in FIG. 1 , except that the corresponding servers are different.

If the data in the local shared information copy of the current terminal is updated, the update refers to the addition, deletion and modification of data. For the updated data, the current terminal will generate unique data corresponding to the update. The identification GUID;

Synchronization information here can have multiple implementation forms, such as taking SyncML (Synchronization MarkupLanguage) as an example, for example, as follows, here is only an example of SyncML, SyncML is a platform-independent information synchronization standard protocol, then the GUID and the indicated fields for the target server are shown in bold font in the following message:

At this point, the current terminal can send the first synchronization information including update data to multiple servers corresponding to multiple services through different synchronization agents, so that the multiple servers can update server data in time. Wherein, the first synchronization information includes updated data, a data synchronization initiator identifier, and a target server identifier.

In the technical solution of this embodiment, local shared information copies of personal information corresponding to various services are configured in the current terminal. The synchronization information is sent, so that the multiple servers perform data update according to the synchronization information, realizing the data synchronization of multiple service-corresponding servers.

On the basis of the first embodiment, it is further possible to implement information synchronization between the multiple servers and multiple terminals in the synchronization terminal set. The synchronization terminal set refers to the data synchronization required by the same user. A collection of terminals. Referring to FIG. 4, it is a flow chart of Embodiment 2 of a data synchronization method provided by the present invention. This embodiment may specifically include:

Step 401: the current terminal configures local copies corresponding to multiple services as a local shared information copy.

Step 402: The current terminal configures multiple synchronization agents for the local shared information copy.

Step 403: When the data in the local shared information copy of the current terminal is updated, the current terminal sends first synchronization information carrying updated data to multiple servers corresponding to the multiple services.

Step 404: The multiple servers perform data update in the servers according to the update data in the first synchronization information.

After the multiple servers receive the first synchronization information carrying update data sent by the current terminal, they extract content of the update data, and perform data update in the servers. If the update is an increase, the update data carried in the first synchronization information is added to the server; if the update is deletion, the server deletes the update data carried in the first synchronization information; if the update is a modification, Then modify the corresponding data in the server according to the first synchronization information.

For the implementation of steps 401 to 404, reference may be made to steps 201 to 202 in Embodiment 1, which will not be repeated here.

Step 405: Any server among the plurality of servers sends the second synchronization information carrying the update data to other terminals in the synchronization terminal set except the current terminal.

Through the steps 401-404, the data synchronization between multiple servers is realized. If the data synchronization between the multiple servers and multiple terminals in the synchronization terminal set is to be further realized, then the multiple Any server among the servers sends synchronization information to other terminals other than the current terminal. Here, any server among the plurality of servers that sends synchronization information to other terminals other than the current terminal is recorded as the master synchronization server. Specifically, it may be realized by indicating a main synchronization server in the first synchronization information, and the main synchronization server is any server among the plurality of servers.

First, the master synchronization server sends the second synchronization information carrying the update data to other terminals in the synchronization terminal set except the current terminal. The update data carried in the second synchronization information is the same as the update data carried by the current terminal in the first synchronization information. terminal.

In practical applications, the synchronization process between the terminal and the server generally adopts the following two methods: (1) The terminal periodically sends a synchronization request to the server, and the server informs the terminal that synchronization is required in the response message, and then the two perform the synchronization process; (2) The server actively sends a notification message to the terminal to notify the terminal to perform information synchronization, and then the two perform the synchronization process.

Step 406: The other terminal updates data in its local copy of shared information according to the second synchronization information.

After other terminals receive the second synchronization information, they can update the data in their local copy of the shared information according to the update data indicated in the second synchronization information.

In this embodiment, in addition to realizing the beneficial effects of Embodiment 1, further, the main synchronization server needs to send synchronization information to terminals other than the current terminal to perform data synchronization, thereby realizing information synchronization of terminals in the synchronization terminal set, So far, information synchronization between multiple servers and multiple terminals has been realized, which provides convenience for users to use personal information.

It should be noted that, in actual operation, the current terminal may first send synchronization information to the main synchronization server, then the main synchronization server performs data synchronization with other terminals, and finally, the current terminal performs data synchronization with other servers; or , after the current terminal sends synchronization information to the primary synchronization server indicated by the first synchronization information, it performs a process of data synchronization with other servers, and finally, performs a process of data synchronization between the primary synchronization server and other terminals.

It can be seen from Embodiment 1 and Embodiment 2 that when the information of any terminal in the synchronous terminal set is updated, the information synchronization between the terminal and the server can be realized. Of course, in practical applications, there is such a A situation where data is updated on any of multiple servers. At this point, you can refer to FIG. 5 , which is a flow chart of Embodiment 3 of a data synchronization method provided by the present invention. When any server data in multiple servers is updated in this embodiment, how to realize multiple servers and The information synchronization of multiple terminals in the synchronous terminal set is described in detail. This embodiment can specifically include:

Step 501: The current server sends third synchronization information carrying updated data in the current server to multiple terminals in the synchronization terminal set.

The current server is the server whose data is updated among the multiple servers. The update of the data in the current server means that the data in the current server has been added, deleted or modified. For the updated data, a unique corresponding to the updated data will be generated on the current server. Identify the GUID;

In addition to carrying the GUID of the updated data in the third synchronization information, it also indicates the identity of the originator and the identity of the receiver of the updated data,

Step 502: The multiple terminals update information in the local copies of shared information of the terminals according to the third synchronization information.

After receiving the synchronization information carrying updated data from the current server, multiple terminals in the synchronous terminal set extract the updated data and update the data in their information copy.

Step 503: Any terminal in the synchronizing terminal set sends fourth synchronization information carrying updated data in the current server to other servers among the plurality of servers except the current server.

Similar to the step 405, if the data synchronization between the multiple servers and the multiple terminals in the synchronization terminal set is to be further realized, then any terminal in the multiple terminals needs to send data to other terminals other than the current server. The server sends synchronization information. Specifically, it may be implemented by indicating a master synchronization terminal in the third synchronization information, where the master synchronization terminal is any terminal among the plurality of terminals.

Here, any one of the terminals is referred to as the primary synchronization terminal, and the terminal of the primary synchronization terminal needs to trigger data synchronization with other servers in addition to updating the data of its own local shared information copy. The third synchronization information carries data to be synchronized, an identifier of a synchronization initiator, and an identifier of a receiver.

Step 504: The other server updates data in the server according to the fourth synchronization information.

After receiving the synchronization information sent by the master synchronization terminal, other servers except the current server extract the data to be updated and update the data in the server. It should be noted that, in actual operation, the current server may first send synchronization information to the main synchronization terminal indicated by the third synchronization information, then the main synchronization terminal performs data synchronization with other servers, and finally, the current server performs data synchronization with other terminals A process of data synchronization; or, after the current terminal sends synchronization information to the main synchronization terminal indicated by the third synchronization information, it performs a data synchronization process with other terminals, and finally, performs a data synchronization process between the main synchronization terminal and other servers.

In the technical solution of this embodiment, when the current server data in the multiple servers is updated, the current server initiates the data synchronization process, and finally realizes the information synchronization between multiple servers and multiple terminals in the synchronization terminal set . It is convenient for users to share information between different servers and terminals.
