Description

A kind of method of data synchronization

Technical field

The present invention relates to a kind of method of data synchronization, particularly relate to the method for data synchronization of client process when the last time, synchronously middle server end returned status of fail, to improve synchronizing quality.

Background technology

Along with the development of mobile communication technology, the value-added service of more portable terminal is developed, and SyncML (Synchronization Markup Language, synchronization makeup language) simultaneous techniques is exactly one of them.SyncML is a kind of and information synchronization standard agreement platform independence.The most existing synchronization solutions overwhelming majority depends on certain manufacturer, application, or certain operating system, and the purpose of SyncML will provide an open standard exactly.At present, this standard has obtained the support of the product of more companies.

See also shown in Figure 1ly, be client in the prior art and the synchronous general flow schematic diagram of server end.This flow process comprises the steps: step 101, and user (User) 10 starts synchronously; Step 102, then, client (Client) 20 beginning initialization; Step 103, netinit subsequently; Step 104 is carried out synchronous initiation in succession after the netinit; Step 105, subsequently, the data of client 20 are sent to server end (Server) 30; Step 106, server end 30 receive and in addition reference, its data is increased, revises, deletes, subsequently, the data of server end 30 with and conditional code be sent to client 20; Step 107, client 20 receive and increase, revise, delete self data with reference to these data, send map information and conditional code immediately and are returned to server end 30; Step 108, server end 30 receives the back transmit status and is returned to client 20, thereby has realized both sides' data synchronization process.

But SyncML DS (Data Synchronization, data sync) agreement is not stipulated client and is sent interpolation, renewal, deleted data to server end, the processing method when server end returns the status of fail sign indicating number.To this, the general way that adopts is that it is ignored, promptly, in data of send server return state failure not synchronously time the next time, but this can cause the inconsistent problem of data of server end and client again, slowly synchronously all data of client are all sent to server end unless start, and this will cause synchronizing quality can't satisfy user's demand.

Described method of data synchronization, wherein, in the described step 21, described user imports synchronous starting command by user interface.

A kind of method of data synchronization that the present invention proposes, realized when last synchronously middle server end returns the status of fail sign indicating number that upgrades failure, deletion failure, interpolation failure, transmit the data of last modification after synchronously next time synchronously the time simultaneously and lastly server end takes place in synchronously and upgrade failure, deletion failure, add the object of failure, thereby improve synchronizing quality.

Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.

Description of drawings

Fig. 1 is client and the synchronous general flow schematic diagram of server end in the prior art;

Client process flow schematic diagram when Fig. 2 returns the status of fail sign indicating number for server end of the present invention.

Embodiment

See also shown in Figure 2, client process flow when returning the status of fail sign indicating number for server end of the present invention.This flow process comprises the steps:

Step 210, under the holding state, the user imports synchronous starting command by UI (User Interface, user interface);

Step 220 starts synchronously;

Step 230 reads all data messages of phone directory from phone directory, comprising: LUID (LocallyUnique Identifier, local unique identification), Date data such as (revising the date);

Step 240, with the phone directory data that read one by one with LogList (log list) in data message compare, specifically comprise:

If there is not the LUID of data in the phone directory among the LogList, then this data message is added to the AddList (adding tabulation) of SyncList (tabulation synchronously), add among the LogList simultaneously;

If the LUID of data in the phone directory is arranged among the LogList, then relatively and revise Date: if the Date in the phone directory is more Zao than the Date among the LogList, then this Date data message in the phone directory is added to the UpdateList (upgrading tabulation) of SyncList, and upgrade the Date among the LogList; If the Date in the phone directory is identical with the Date among the LogList, the data in the then more next phone directory;

If there are not the data of LogList in the phone directory, then it added to the DeIeteList (deletion tabulation) of SyncList, and in LogList, delete corresponding data information.

Step 250, client Client transfers to server end Server to the concrete data content among the SyncList and the corresponding command;

Step 260, server end Server returns success or the status of fail sign indicating number to client Client each data;

Step 270, does the conditional code that client Client reception server end Server returns also judge that this conditional code is success status sign indicating number or status of fail sign indicating number? if the success status sign indicating number, then execution in step 280, if the status of fail sign indicating number, then execution in step 290;

Step 280, the information of the corresponding data of success status sign indicating number among the deletion SyncList, and change step 210;

Step 290 is not deleted object corresponding among the SyncList, that is, keep the information of the corresponding data of status of fail sign indicating number in SyncList, and change step 210.

In the above-mentioned explanation of Fig. 2, LogList is the log list that generates when reading the phone directory data when client Client initialization, and this table is corresponding one by one with the data in the phone directory, data such as the local unique identification of this table storage, Date.

The synchronous tabulation of SyncList generation when when client Client initialization the phone directory data that read being compared with LogList comprises three aspects:

If there are not the data in the phone directory among the LogList, then add the AddList of these data, and add among the LogList to SyncList;

If the Date of data is greater than the Date of data among the LogList in the phone directory, then adds the UpdateList of these data, and upgrade the Date among the LogList to SyncList;

If the data in the phone directory among the no LogList are then added the DeleteList of these data to SyncList, and delete corresponding data from LogList.

In Fig. 2, after this subsynchronous end, during down subsynchronous startup, execution in step 210,220, after 230 and 240, data except changing in the phone directory of last subsynchronous back among the SyncList, the data of the status of fail sign indicating number correspondence that the server end Server that receives in upward subsynchronous in addition returns, promptly add or upgrade or delete the data message of failure at server end Server, execution in step 250 more subsequently, so just can overcome existing synchronously in server end Server add or upgrade or deletion failure and incured loss through delay the renewal of local data and then the problem of bringing synchronizing quality to reduce.

The present invention is because of after the data that only relate to client and send are sent to server end, and server end returns the step of this data synchronization conditional code synchronously after these data, so, other flow process of omission among Fig. 2.

A kind of method of data synchronization that the present invention proposes, realized when last synchronously middle server end returns the status of fail sign indicating number that upgrades failure, deletion failure, interpolation failure, transmit the data of last modification after synchronously next time synchronously the time simultaneously and lastly server end takes place in synchronously and upgrade failure, deletion failure, add the object of failure, thereby improve synchronizing quality.

Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
