The present invention relates to synchronization, and more particularly, to a synchronization method using a markup language for synchronization and a mobile communication terminal.

Synchronization Markup Language (Synchronization Markup Language) protocol is a standard proposed to ensure the uniformity of distributed data. It is used for synchronization to match data between different devices and application services.

Synchronization Markup Language (SyncML) performs synchronization between a server and a client by sending and receiving a message including data expressed in the form of an extensible Markup Language (XML) between the server and the client.

Synchronization between server and client using Markup Language (SyncML) for synchronization includes Normal (two-way sync), Restore (Refresh sync from server only) and Backup (Back-up; Refresh sync from client only). And the like.

Normal synchronization is a synchronization method of comparing data between a mobile communication terminal and a synchronization server and storing the latest data in a mobile communication terminal or a synchronization server.

Restore synchronization is a synchronization method of deleting data of a mobile communication terminal and storing the data in the mobile communication terminal as synchronization data received from a synchronization server.

Back-up synchronization is a synchronization method in which data of a synchronization server is deleted and stored in the synchronization server as synchronization data received from a mobile communication terminal.

Therefore, even if a failure occurs during backup synchronization, the synchronization server is not a big problem because it includes restoration functions for various failures.

However, when a restore synchronization is performed, the mobile communication terminal deletes the data stored in the storage device first. Therefore, if a failure occurs during the recovery synchronization, the mobile communication terminal cannot use the mobile communication terminal because there is no recovery function for the deleted data. There was no problem.

Summary of the Invention An object of the present invention for solving the above problems is a synchronization method and a mobile communication terminal in which all existing data stored in the mobile communication terminal are not deleted even if the restore session is terminated for an abnormal reason.

It includes.

Here, the temporary storage device is a temporary storage space of an external storage device or a temporary storage space of an internal storage device.

Here, when the size of the received synchronization data is smaller than the storage capacity of the temporary storage space of the external storage device, the synchronization data is stored in the temporary storage space of the external storage device.

Here, when the size of the received synchronization data is larger than the storage capacity of the temporary storage space of the external storage device, but smaller than the storage capacity of the temporary storage space of the internal storage device, the synchronization data is the internal storage device.

The temporary storage space 116t of the internal storage device 116 of the storage device 114 or the temporary storage space 117t of the external storage device 117 is controlled to be temporarily stored.

In addition, when all the synchronization data is received from the synchronization server 120 into the temporary storage space 116t of the internal storage device 116 or the temporary storage space 117t of the external storage device 117, The synchronization data temporarily stored in the temporary storage space 116t of the storage device 116 or the temporary storage space 117t of the external storage device 117 is controlled to be stored as a space in which the data is stored in the internal storage device 116.

Here, a description will be given of a method for preventing a failure from occurring while restoring synchronization between the mobile communication terminal 110 and the synchronization server 120 is performed so that all data stored in the mobile communication terminal 110 is deleted. 6 will be described in detail.

4 is a flowchart illustrating a synchronization method of a mobile communication terminal according to the first embodiment of the present invention.

2 to 4, the synchronization method of the mobile communication terminal according to the first embodiment of the present invention analyzes whether the storage space of the temporary storage device 118 is sufficient in the mobile communication terminal 110 (S210). .

Here, the temporary storage device 118 is either a temporary storage space 116t of the internal storage device 116 of the mobile communication terminal 110 or a temporary storage space 117t of the external storage device 117.

When the storage space of the temporary storage device 118 is not sufficient, the mobile communication terminal 110 performs a basic restore synchronization (S230) and the temporary storage device 118 according to the analysis result. If there is enough storage space, Extended Restore Sync (ExtRestore Sync) is performed (S220).

Here, since the storage device 114 of the mobile communication terminal 110 includes the internal storage device 116 or the external storage device 117, the storage space of the temporary storage space 117t of the external storage device 117 is possible. If this is sufficient, the mobile communication terminal 110 temporarily stores the synchronization data received from the synchronization server 120 into the temporary storage space 117t of the external storage device 117.

In addition, if there is no storage space of the temporary storage space 117t of the external storage device 117 and the storage space of the temporary storage space 116t of the internal storage device 116 is sufficient, the mobile communication terminal 110 is internal. The temporary storage space 116t of the storage device 116 temporarily stores the synchronization data received from the synchronization server 120.

Here, the size of the storage space of the temporary storage space 117t of the external storage device 117 or the storage space of the temporary storage space 116t of the internal storage device 116 may be the synchronization data to be transmitted from the synchronization server 120. It must be greater than the size of.

That is, the mobile communication terminal 110 has a predetermined size of the internal memory 116 at the time of manufacturing the mobile communication terminal 110, and the external storage device 117 is already inserted into the mobile communication terminal 110 to have a capacity. Is measured.

Accordingly, the mobile communication terminal 110 may store the temporary storage space 116t of the internal storage 116 or the temporary storage space 117t of the external storage 117 capable of temporarily storing synchronization data. Can be checked before synchronization with the synchronization server 120.

Here, basic restore synchronization and extrestore sync will be described in detail with reference to FIGS. 5 and 6.

5 is a sequence diagram illustrating an ExtRestore method of a synchronization system according to a first embodiment of the present invention.

3 and 5, the mobile communication terminal 110 opens a synchronization session with the synchronization server 120 (OPEN or CREATE) and makes a synchronization request to the synchronization server 120 (S310).

The synchronization server 120 generates synchronization data (S320).

The synchronization server 120 transmits the generated synchronization data to the mobile communication terminal 110 (S330).

The mobile communication terminal 110 temporarily stores the synchronization data transmitted from the synchronization server 120 in the temporary storage device 118 (S340). Here, the mobile communication terminal 110 converts the file name of the synchronization data into a locally unique identifier (LUID) format and temporarily stores it in the temporary storage device 118.

When the synchronization data is temporarily stored, the mobile communication terminal 110 closes the session between the mobile communication terminal 110 and the synchronization server 120 (CLOSE or DESTROY).

It is processed in a single session from the synchronization request (S310) to the step in which the synchronization material is temporarily stored (S340). Here, the description of the session is omitted because it is described in detail in the SyncML specification.

When the synchronization data received from the synchronization server 120 is temporarily stored in the mobile communication terminal 110, the mobile communication terminal 110 deletes the data previously stored in the internal storage device 116 (S350). Here, the pre-stored data is different from the synchronized data received from the synchronization server 120 and temporarily stored in the temporary storage device 118.

The mobile communication terminal 110 performs synchronization to restore the synchronization data temporarily stored in the temporary storage device 118 to the data of the internal storage device 116 (S360).

As a result, ExtRestore Sync does not delete the data of the mobile communication terminal 110 until the session between the mobile communication terminal 110 and the synchronization server 120 is completed. The synchronization data transmitted from 120 is temporarily stored in the temporary storage space 117t of the external storage device 117 or the temporary storage space 116t of the internal storage device 116.

Thereafter, the mobile communication terminal 110 deletes the previously stored data and then restores the synchronization data temporarily stored in the temporary storage 118 to the internal storage 116 of the mobile communication terminal 110. Do this. Therefore, the mobile communication terminal 110 can prevent the data of the mobile communication terminal 110 from being deleted due to the unexpected disconnection of the session during synchronization.

Next, a synchronization method for the case where the storage space of the temporary storage device 118 is insufficient in the mobile communication terminal 110 will be described in detail with reference to FIG. 6.

6 is a sequence diagram illustrating a basic recovery synchronization method of a synchronization system according to a first embodiment of the present invention.

3 and 6, the mobile communication terminal 110 deletes data previously stored in the internal memory 116 of the mobile communication terminal 110 (S410).

The mobile communication terminal 110 makes a synchronization request to the synchronization server 120 (S420).

The synchronization server 120 generates the synchronization data (S430).

The synchronization server 120 transmits the generated synchronization data to the mobile communication terminal 110 (S440).

The mobile communication terminal 110 performs restore synchronization in which the synchronization data received from the synchronization server 120 is stored in the internal storage 116 (S450).

Next, the mobile communication terminal 110 will be described in detail with reference to FIG. 7 for synchronization with the synchronization server 120 through the mobile communication network.

7 shows a synchronization system 500 according to a second embodiment of the present invention.
