EMBODIMENT OF THE INVENTION Hereinafter, the Example by this invention is described in detail with reference to an accompanying drawing.

1 is a schematic diagram illustrating the overall environment and the present invention in which the system and method according to the present invention are implemented.

First, as shown in the drawing, the system according to the present invention receives and stores data to be backed up from a wireless mobile communication terminal before replacement through a wireless mobile communication network, converts the data into a predetermined format, if necessary, and converts the wireless mobile communication network. And a backup server 30 for transmitting data stored in connection with the wireless mobile communication terminal after the replacement, and is connected to the terminals 10 and 20 before and after the replacement through the wireless mobile communication network.

The terminal before the replacement is indicated by reference numeral 10 and the terminal after the replacement is indicated by reference numeral 20.

The terminals 10 and 20 and the backup server 30 are connected to each other through a wireless mobile communication network. For example, the terminals 10 and 20 and the backup server 30 may transmit and receive data through a wireless Internet or a Short Message System (SMS) system. The present invention is not particularly limited to these methods.

The terminals 10 and 20 are wireless mobile communication terminals, each having its own physical space as a storage means capable of storing data such as a phone book and an address book, such as a RAM and a ROM. The drive software that can perform functions such as deletion and editing is built in. In addition, the terminal 10, 20 has a built-in backup / recovery module for backup / recovery. These backup / recovery modules and the driving software may be installed at the time of manufacture of the terminal, or may be installed later in the form of a download through wireless internet or a data cable connection with a computer.

If the terminal 10 before the replacement and the terminal 20 after the replacement are all manufactured by the same manufacturer, even if the model number is different, since the basic hardware and software configuration is the same, there will be most cases where there is no problem in data compatibility. Of course, if not, that is, even if manufactured by the same manufacturer, the model number is different, and even if the hardware and / or configuration of the software is not guaranteed data compatibility due to different configurations of the present invention can be applied to the specific description thereof will be described later. If the manufacturer before the terminal 10 and the terminal 20 after the replacement is different from each other, the principle is to see that there is no data compatibility, in this case, the present invention can be applied as it is. In short, the present invention is characterized in that the present invention can be applied even when data compatibility caused by different configurations of hardware and / or software between terminals before and after replacement is not guaranteed.

The backup server 30 receives and stores data to be backed up from the before-replacement terminal 10, performs a data conversion process if necessary, and then connects to the after-replacement terminal 20 to transmit backup data. As a server to perform, a specific configuration of the server will be described later.

Meanwhile, the backup server 30 may be connected to a computer through an internet network. In this case, a user may access the backup server 30 through a computer and an internet network to view, modify, and edit backup data. Of course, it can also be done. The backup server 30 may be connected to the backup server 30 through the computer, and the backup data stored in the backup server 30 may be downloaded to the computer and then stored in the terminal through a data cable connection with the terminal.

2 is a block diagram showing the detailed configuration of the backup server 30 of FIG. In the configuration diagram of the backup server 20 of FIG. 2, the components of the general server and the components for wireless mobile communication are omitted, and only the configuration related to the present invention is shown.

As shown in FIG. 2, the backup server 30 includes a backup data receiver 31, a backup data manager 32, a backup data format converter 33, a database 34, and a backup data transmitter 35. do.

The backup data receiver 31 is a module that is connected to the terminal 10 before the replacement through a wireless mobile communication network and receives the backup data transmitted by the terminal 10.

In addition, the backup data management unit 32 first stores the backup data received by the backup data receiving unit 31 in a storage space in the form of raw data, and performs or instructs operations such as data processing, editing, and conversion. Data management means.

On the other hand, the backup data format conversion unit 33 is a means for performing various conversion processes including various processing, editing, and the like on the stored data according to the instructions of the backup data management unit 32.

The database 34 primarily means a physical storage space such as a hard disk, for example, but includes software driving means for managing the physical storage space.

On the other hand, the backup data transmission unit 35 after the user replaces the terminal, after replacing the backup data stored in the case of requesting the backup data transfer to the backup server 30 through the terminal 20 after replacement; Means for transmitting to the terminal 20 side.

3 is a diagram illustrating a driving program and a backup / recovery module 40 installed on the terminals 10 and 20. The backup / recovery module 40 of FIG. 3 may be installed from the time of manufacture of the terminal, or may be installed by downloading by accessing the backup server 30 after the user purchases the terminal. Even if the backup server 30 is not necessarily, it can be installed by the service provided by each mobile operator. The backup / recovery module 40 is stored in internal storage means such as memory of the terminals 10 and 20.

4 is a flowchart illustrating one embodiment of a method according to the present invention. The embodiment of FIG. 4 assumes that the backup / recovery module (see FIG. 3) is pre-installed for data backup / recovery by the terminals before and after replacement, and these backup / recovery modules have hardware and software compatibility with each other. Assume that

First, in step S100, the necessary data is extracted from the data to be backed up by the backup / recovery module 40 of the terminal 10 before the replacement. Extracting data means selecting only data to be backed up from various types of data stored in the terminal 10 before replacement. There are various types of data stored in the terminal such as telephone number, name, address, fax number, speed dial number, recent incoming phone number, recent outgoing phone number. Various types are stored for each model and manufacturer of the terminal. Although all of these data may be backed up, it is desirable to extract the necessary data at the user's choice in consideration of the time and cost of the data backup.

When the extraction of data is completed, the terminal 10 is connected to the backup server 30 and the mobile communication network, and then transfers the data extracted in the step (S100) to the backup server 30 (S110), backup The backup data receiver 31 of the server 30 receives the data transmitted from the terminal 10 (S120). At this time, the data transmission between the terminal 10 and the backup server 30 can be made using a method such as wireless Internet or SMS, the present invention is not limited to this data transmission method.

When data reception is completed in the backup server 30, the backup data management unit 32 of the backup server 30 performs standardization processing on the received data (S130). Here, standardization processing means processing in a data format of a unified format. That is, it means processing different types of data having various formats for each terminal, for example, an identification field name of data and a length of data, in a standardized form. For example, the name of a person is commonly given a field name of NAME, the length of data is set to 12 bytes in length, the telephone number is assigned to a field name of NUMBER, and the length of data is set to 16 bytes in length. Processed data. At this time, unnecessary data may be deleted and new data may be added in some cases for the standardization process.

When the standardization process is completed, the backup data management unit 32 of the backup server 30 stores the data in the database 34 (S140).

In the state where the standardized data is stored in the backup server 30 as described above, the backup server 30 replaces the terminal for any reason and then uses the stored data in the terminal 20 after the replacement. After the replacement, the terminal 20 waits for access to the backup server 30 to request to restore the backup data (S150).

If the user has a request for data recovery, the backup data transmitter 35 of the backup server 30 transmits the data stored in the terminal 20 side (S160), and the terminal 20 receives the data (S170).

When the data reception is completed, since the received data is standardized data, the backup / recovery module of the terminal 20 performs a customization process for each terminal on the received data (S180). The customization process is an opposite concept to the above-described standardization process, which means that the data format is changed, data is added or deleted, etc. in accordance with the format of the field name, data length, and the like used for each terminal. Of course, if the standardized data can be used as it is, this step can be omitted.

When the customization process is completed, the terminal 20 stores the data in the storage means provided therein (S190).

5 is a flowchart showing another embodiment of the method according to the present invention, in which the standardization process and the customization process described in FIG. 4 can be processed in a single process on the backup server 30 side. .

Steps S200 to S220 are the same as steps S100 to S120 of FIG. 4, and thus descriptions thereof will be omitted.

Next, in step S230, the backup data management unit 32 of the backup server 30 stores the data in the database 34. Of course, the data at this time is the data which has not been normalized as compared with the embodiment of Fig. 4, that is, the data and the format of the data transmitted from the terminal 10 before replacement are preserved as they are.

Next, the terminal 20 waits for a request to restore the backup data by connecting to the backup server 30 from the terminal 20 after the replacement (S240).

After the replacement is connected to the backup server 30 via the terminal 20, there is a data recovery request, when the connection to the backup server 30, the backup / recovery module 40 of the terminal is unique identification information of the terminal (manufacturer , Model number, etc.) is transmitted to the backup server 30 (S250).

The backup server 30 receives the unique identification information of the terminal, checks the data format of the terminal in a database previously stored for each terminal, and then performs data customization processing in accordance with the data format (S260). Since this customization process is the same concept as the customization process of step S180 of FIG. 4, detailed description is abbreviate | omitted.

When the customization process is completed, the backup server 30 transmits data to the terminal 20 (S270), and the terminal 20 receives and stores the data (S280 and S290).

FIG. 6 is a flowchart showing another embodiment of the method according to the present invention, further comprising converting data into a specific format on the terminal (10, 20) side. Converting to a specific format means that it has a data format of a format such as XML or SyncML, and that each terminal can accept and edit the internal database, backup / recovery module, and a browser that can view and edit them. (Or an editor).

First, in step S300, the terminal 10 before replacement selects and extracts data to be backed up. This process is the same as step S100 of FIG. 4, and thus description thereof is omitted.

Next, the terminal 10 converts the extracted data into data of a specific format (eg, XML or SyncML) (S310). This particular format should be set in advance to be common to both before and after the replacement terminal (10, 20) and the backup server (30).

When the data conversion is completed, the terminal 10 is connected to the backup server 30 and the mobile communication network, and then transfers the data converted in the step S310 to the backup server 30 (S320), the backup server The backup data receiver 31 of 30 receives the data transmitted from the terminal 10 (S330), and stores the received data in an internal database (S340).

Next, the backup server 30 waits whether the terminal 20 after the replacement requests to connect to the backup server 30 to restore the backup data (S350). The backup data transmitter 35 of the server 30 transmits the data stored in the terminal 20 side (S360), and the terminal 20 receives the data (S370).

Next, after the replacement, the terminal 20 converts the data of a specific format received from the backup server 30 (for example, parsing the data in the case of XML or SyncML format) (S380), and stores the data. (S390).

7 is a flowchart illustrating another embodiment of the method according to the present invention, in which the terminal 10 before the replacement cannot handle data conversion of a specific format as described in FIG. This embodiment will be mainly applied when the terminal 10 before the replacement has a long time since the purchase.

First, in step S400, the replacement terminal 10 selects and extracts data to be backed up. Next, after the terminal 10 is connected to the backup server 30 side, and transmits the data extracted in the step (S400) to the backup server 30 (S410), the backup data receiving unit of the backup server 30 31 receives data transmitted from the terminal 10 (S420). Up to this point, the process is the same as the steps S100 to S120 described with reference to FIG. 4.

Next, the backup server 30 performs a process of converting the data into a specific format as described in step S310 of FIG. 6 with respect to the transmitted data (S430). That is, in the embodiment of FIG. 6, the data conversion process performed at the terminal 10 is performed by the backup server 30.

When the data conversion is completed, the backup server 30 stores the data (S440), waits for the backup data recovery request of the terminal 20 after the replacement (S450), and transmits the data to the terminal 20 by the recovery request. It becomes (S460). Subsequent steps S470 to S490 are the same as steps S370 to S390 of FIG. 6, and thus description thereof is omitted.

On the other hand, in the embodiments of Figs. 4, 5, 6 and 7, it is assumed that all the terminals before and after the replacement are provided with backup / restore modules in any form in advance. As described above, the backup / recovery module may be installed at the time of manufacturing the terminal, but each terminal is connected to the backup server 30 at each step of starting the backup / recovery in FIGS. 4 to 7. It may further comprise the step of connecting to download and install the backup / recovery module.

That is, the terminal 10 before the replacement is connected to the backup server 30 in the first step of backing up the data to select and download the backup / recovery module for the terminal, and after the replacement terminal 20 requests the data recovery When the first step is to access the backup server 30 to select the backup / recovery module for the corresponding terminal to download, it is possible to select the latest backup / recovery module most suitable for the terminal.

In addition, in the embodiments of FIGS. 4 to 7, the encryption and decryption steps may be further provided. That is, the terminal 10 may be encrypted before the replacement and the terminal 20 may be decrypted after the replacement. However, if data is encrypted at the terminal side, it may be impossible to perform data conversion operations such as standardization processing as described in FIG. 4 at the backup server side. In this case, the backup server does not perform standardization processing or format conversion, but stores the data transmitted from the terminal as it is and transfers the data to the terminal after replacement. Alternatively, when encrypting data at the terminal side, a method of encrypting a fixed field (eg, a name field) with a fixed length (eg, 12 bytes) and maintaining the order may be used. Using this method, data processing tasks such as standardization and format conversion of data can be performed on the backup server side.

In addition, in each of the embodiments of FIGS. 4 to 7, the data backup process may be performed at a predetermined time and in accordance with a user's preset time. For example, a backup server may be automatically accessed every night, every week, and every month to transmit an item set by a user (eg, a phone number and a name).

In addition, in the embodiments of FIGS. 4 to 7, the user may access the backup server through a computer and a wired Internet network, so that the user may view, edit and download the backup data using the computer. After downloading data through a computer, it is also possible to recover the data by transferring the data to the user's terminal through a cable connection with the computer.

In the above, preferred embodiments of the present invention have been described, but the present invention is not limited to the above embodiments, and various modifications and variations of the embodiments may be possible. Therefore, the true scope of the present invention should be interpreted with reference to the following claims as well as the above embodiments.

According to the present invention, by easily backing up and restoring the data of the wireless mobile communication terminal, even if the terminal is lost or replaced, the previously used data can be used as it is. It is possible to provide a system and method capable of processing data without the need to do so.

In addition, according to the present invention, the user can set the time, type, and the like of the data backup in advance, thereby facilitating the user's convenience, and also encrypting and decrypting the data in parallel with the data backup and recovery process. Systems and methods can be provided to ensure safety.
