Abstract

A method of updating and rolling back data of terminal device is disclosed. The method comprises backing up the data that needs to be updated in the terminal device before the terminal device performing data updating operation, so as to solve the problem in prior art for big consumption of the server resource and network resource, and it can also avoid the problem for data transmission being fault easily. By the method according to present invention, there is no need to transmit the backup data when rolling back, thus saving the network resource and reducing the data amount transmitted through the network. If users find faults after updating, they can find out the backup data and roll back the data by themselves. And if operators find faults after updating, they can send a rollback request from the server side to the terminal device and roll back the data.

Description

Method for updating and restoring terminal device data

Technical field

The present invention relates to the field of communications and information technology, and more particularly to a method of updating and restoring terminal device data. Background technique

Mobile terminal equipment is an important part of the entire mobile operation service system. As the functionality of terminal devices becomes more complex, the likelihood of problems with the terminal device software increases significantly. How to quickly and effectively solve problems in the terminal, improve service quality, and reduce operating costs of system equipment has become a concern of terminal equipment manufacturers.

In the existing Mobile Alliance Device Management (OMADM) specification, the system provides a mechanism for configuring terminal device parameters from the server side and transmitting update packages to the terminal devices to update the terminal device software. However, when the parameter configuration or the software update package is successfully updated, when there is a logical problem (for example, the updated software still has errors or the updated parameters are not available for the software, etc.), how to restore the state before the update still needs to be effective. The solution to solve.

The current method is to back up the data before the update on the server side, and re-issue the data before the update when a logic error occurs to complete the data recovery.

FIG. 1 is a flow chart of data backup and data update signaling in the prior art. Referring to FIG. 2, the process flow is as follows:

Step 1: Establish a connection between the server and the terminal device according to the OMA DM standard; Step 2: The server sends a parameter acquisition configuration message according to the data involved in the update; Step 3: The terminal device configures a message according to the acquired parameter, ^Reminder, and upload the corresponding parameter data;

Step 4: After receiving the uploaded data, the server backs up the data on the server side.

Step 5: The server sends an update package, and the terminal device receives the update operation. Step 6: The terminal device reports the update status.

When the user finds that there is a problem with the parameter configuration and needs to revert to the pre-update configuration, refer to the prior art data recovery signaling flowchart shown in Figure 2. As shown in the figure, the process flow is as follows: Step 1: According to OMA DM The standard establishes a connection between the server and the terminal device; Step 2: The terminal device informs the server of the parameters that need to be restored by telephone, WEB or other means;

Step 3: The server delivers an update package, and the content of the update package is related data backed up before the last update;

Step 4: After the terminal device receives the update package, it performs an update operation and completes the recovery.

Through the above data backup and data update process, it can be seen that backup data on the server side occupies server resources; since the data is backed up on the server side, and the original data is on the terminal device, it is necessary to upload relevant data before each update, and increase The consumption of network resources is large; and the transmission of data on the mobile network will increase the probability of error.

Through the above data recovery process, it can be seen that since the data is backed up on the server side, each recovery requires the server to issue relevant data, which increases the consumption of network resources; transmitting data on the mobile network will increase the probability of error; At present, the user cannot recover by itself. The user can notify the server side to cooperate with the server through the telephone or the WEB to initiate the recovery process. If the operator finds an error, the server cannot actively recover. Summary of the invention

In order to save server and network resources when updating data, and reduce the amount of data transmitted by the network, the present invention provides a method of updating terminal device data in device management. The data management structure of the terminal device is a tree structure, or uses a database or a data list to compare data. Manage. Now taking the data management structure as a tree structure as an example, the method of the present invention will be described below with reference to examples.

Example 1: The update process is initiated by the terminal device, and different versions of the data to be updated are backed up under the same ^ node. FIG. 3 is a flowchart of a method according to the present invention. FIG. 4 is a signaling flowchart of a method according to the present invention. Referring to FIG. 3 and FIG. 4, the method includes the following specific steps: S11, a terminal device, and a device management server. (DM Server) establishes a connection.

The user terminal device sends a connection establishment request message to the DM server, and after receiving the message, the DM server sends a response message to the user terminal device to complete the connection between the user terminal device and the DM server.

S12. The terminal device sends a data configuration request message to the DM server.

After the connection is established, the user initiates the update process. The terminal device constructs a data configuration request message according to the data content updated by the user and the path of the node where the data is located. And sending, by the terminal device, the data configuration request message to the DM server, to notify the DM server of the update data, and configuring the DM server to perform corresponding configuration according to the path, so that the update is updated. Data can be automatically copied to the corresponding data node.

513. The DM Server sends the update data according to the content of the received data configuration request message.

After receiving the data configuration request message, the DM server obtains the data content that the user wants to update, and the path of the data, and constructs the related data as an update data packet, and sends the data to the user terminal device.

514. Create a backup node under the data node to be updated.

Figure 5 shows the data structure before the backup node is created. Figure 6 shows the data structure after the backup node is created. The terminal device configures a data path in the request message according to the sent data, and creates a backup node for storing the data to be updated under the node where the data to be updated on the terminal device is located.

515. Back up the data to be updated to the backup node.

Before the backup, the user can determine whether the data to be updated is important, and select whether to back up the data to be updated, which can save time and storage space. As shown in Figure 7, the data structure of the data to be updated is backed up. It can be seen from the figure that the data to be backed up according to the household selection will be The backup data is backed up to the backup node, and the data to be updated is backed up on the terminal device to complete the backup work. If you need to update the data under the same node again, the backup node will not be created. Instead, the data to be updated will be directly backed up to the created backup node and the previous data will be overwritten.

S16, update the data.

After the backup is completed, the terminal device updates itself with the update packet delivered by the DM Server. After the update packet is decomposed, the update data is directly copied to the node corresponding to the update data. FIG. 8 is a schematic diagram of the updated data structure. As can be seen from the figure, after the update, the data to be updated is overwritten by the updated data.

S17. Report the update.

After the update operation is completed. Terminal equipment to the DM Server ^{^:} Gen update was successful.

The sequence between steps S14 and S15 and step S13 described in this embodiment may be interchanged, or steps S14 and S15 may be performed simultaneously with step S13 as long as the update is to be performed before the start of the update data operation. Backing up data to the terminal device should be within the scope of the present invention.

S22. The terminal device sends a data configuration request message to the DM server. (same as the example one)

523. The DM Server sends the update data according to the content of the received data configuration request message. (same content as in example one)

524. Create a backup node with a version number under the data node to be updated.

When the backup needs to be backed up, the terminal device creates a backup node with the current data version number under the node where the data to be updated is located, and stores the data of the current backup. Then, if the data under the same node needs to be updated again, Create a backup node with the current data version number and store the data for that backup. This way the data does not overwrite the previous data for maintenance.

525. Back up the data to be updated to the corresponding backup node. It is up to the user to determine whether the data to be updated is important before the backup, and whether to back up the data to be updated. After the selection, the data to be updated is backed up to the backup node with the same version number, and the data to be updated is backed up on the terminal device to complete the backup work. A schematic diagram of the data structure after the backup, as shown in FIG.

S26, update the data. (same content as in example one)

S27. Report the update. (same content as in example one)

The sequence between steps S24 and S25 and step S23 described in this embodiment may be interchanged, or steps S24 and S25 may be performed simultaneously with step S23, as long as the data to be updated is backed up before the start of the update data operation. It should be within the scope of the present invention to the terminal device.

Example 3: The update process is initiated by the terminal device, and the data to be updated is backed up under any node in the tree structure.

S31. The terminal device establishes a connection with a device management server (DM Server). (same as example one)

S32. The terminal device sends a data configuration request message to the DM server. (same as the example one)

533. The DM Server sends the update data according to the content of the received data configuration request message. (same content as in example one)

535. Back up the data to be updated to the backup node. (same content as in example one)

536, update the data. (same content as in example one)

S37. Report the update. (same content as in example one)

The sequence between steps S34 and S35 and step S33 described in this embodiment may be interchanged, or steps S34 and S35 may be performed simultaneously with step S33, as long as the data to be updated is backed up before the start of the update data operation. It should be within the scope of the present invention to the terminal device. Example 4: The update process is initiated by the terminal device, and the backup tree and backup related data are created.

541. The terminal device establishes a connection with the device management server (DM Server). (same as example one)

542. The terminal device sends a data configuration request message to the DM server. (same as the example one)

543. The DM Server sends the update data according to the content of the received data configuration request message. (same content as in example one)

544. Create a backup node in the tree structure, and create a node structure of all nodes except the node in the original tree structure under the backup node.

Figure 11 shows the data structure after the backup node and other nodes except the original root node are created before the first backup. As can be seen from the figure, a backup node is created under the root node of the tree data structure on the terminal device, and each node having the same structure as the other nodes under the original root node is created under the backup node. These created nodes are used to store data under their corresponding nodes.

The backup node and the backup tree structure under the backup node may also not be created under the original root node, and may be created under any node in the original tree structure.

When the original tree structure changes, the created backup tree structure changes accordingly. S45. Back up at least the data that needs to be updated to the corresponding node under the backup node.

It is up to the user to determine if the data to be updated is important before the backup and to choose whether to back up the data to be updated. Because the node structure under the backup node is the same as the data structure under the original root node, the data under the root node is automatically backed up to the corresponding node under the backup node to complete the backup operation. In this step, only the data that needs to be updated can be backed up to the corresponding node under the backup node to save time and space.

S46. Update the data. (same content as in example one)

S47. Report the update. (same content as in example one)

Similarly, it should be within the scope of the present invention to satisfy the backup of the data to the terminal device before the update data operation begins.

The process of updating the terminal device data according to the present invention may also be initiated by the DM Server. After the connection between the terminal device and the DM Server is established, the DM Server sends the connection to the terminal device. The parameter configuration request message carries a content list that needs to be updated in the parameter configuration request message, so that the terminal device learns the content involved in the current update, and accordingly, the terminal device actively backs up the related data before the update operation starts. The method for actively updating the terminal device data by the DM server may also be implemented by the following process: After the connection between the terminal device and the DM server is established, the parameter configuration request message is not sent, but a creation message is sent. The creation message carries a creation path for informing the terminal device where to create a backup node in the data management structure, for example: creating a backup node under the node where the data to be updated is located; waiting for the terminal device to be created at the corresponding location After the backup node is reported and reported, the DM Server sends a backup message to the terminal device. After receiving the data, the terminal device backs up the corresponding data to the created backup node. After that, the data update process is performed.

If the present invention uses a database or data list to manage data, a corresponding data management structure is established on the device terminal. When backing up, the related data and its path are backed up to the database or data list for subsequent operations to find and call.

In order to save network resources when restoring data, reduce the amount of data transmitted by the network, and enable users to recover data by themselves, the server side can also initiate the recovery process. The method of the present invention utilizes the data backed up by the above scheme to provide a method for restoring terminal device data in device management. The method of the invention will now be described in three examples.

Example 1: The data recovery process initiated by the DM Server. FIG. 12 is a flow chart showing the steps of the method of the present invention. FIG. 13 is a signaling flowchart of the method of the present invention. As can be seen from the above two figures, the method includes the following steps:

Sl, the device management server establishes a connection with the terminal device.

The DM Server sends a connection establishment request message to the user terminal device, and after receiving the message, the user terminal device sends a response message to the DM Server to complete the connection between the DM Server and the user terminal device.

S2. The device management server sends a recovery request message to the terminal device.

After the connection is established, the DM Server initiates the recovery process. The data content corresponding to the error is carried in the recovery request message to inform the terminal device which data needs to be recovered, according to the update error that the operator has confirmed. The recovery request message is then sent to the user terminal device. S3. Extract recovery data from the backup data.

After receiving the recovery request message, the terminal device determines, according to the content in the message, the data that needs to be restored, and searches for and extracts the backup data corresponding thereto, if the manner of creating different backup nodes for different versions of data is adopted. , the user can choose which version of the data to restore.

If the method of creating a backup node under the node where the data to be updated is created is used, as shown in FIG. 8 and FIG. 9, the original path of the data is the upper node of the backup node; if the backup tree is used, Or the method of creating a backup node under any node, as shown in FIG. 10 and FIG. 11, the original path of the data is the path of the node where the original data needs to be restored under the original root node.

S4, overwriting the current data.

According to the original path of the parsed data, the current data is overwritten with the extracted backup data to complete the recovery operation.

S5. Determine whether the recovery is successful, and report the recovery.

After the recovery operation is completed, the terminal device determines whether the recovery is successful. After the judgment result is obtained, the terminal device sends a recovery situation message to the DM server, where the recovery situation message carries a code for identifying the recovery situation, for example: 1 represents recovery success, 2 represents recovery failure, and 3 represents no corresponding recovery data. . After receiving the recovery status message, the DM Server obtains and parses the code, and then determines whether it is necessary to initiate the recovery process again. If the code DM Server according to the recovery situation confirms that the recovery process does not need to be initiated again, a deletion message is sent to the terminal device, and the terminal device is notified to delete the backed up data. After the results show that the recovery is successful, the terminal device can also actively delete the backup data to save storage space. Of course, after the recovery is successful, the backup data may not be deleted for subsequent processes.

Example 2: The user recovers the data autonomously.

Sl. When the user finds a problem after the update, the recovery process can be initiated autonomously.

S2. Determine the data that needs to be recovered according to the found error, and extract the recovered data from the backup data, and parse the original path of the data.

53. Overwrite the current data with the extracted data.

54. After the recovery operation is completed, determine whether the recovery is successful. If the recovery is successful, the backup data may be deleted or not deleted. Example 3: Upload the backup data and then deliver it.

51. The device management server establishes a connection with the terminal device. (same content as in Example 1)

52. The DM Server extracts corresponding data and its path from the terminal device according to the data content that needs to be restored.

53. The data is packaged and sent to the terminal device.

54. The terminal device overwrites the current data with the data in the data packet.

S4. After the recovery operation is completed, it is judged whether the recovery is successful, and the recovery situation is as follows. (same content as in Example 1)

The above embodiments are intended to illustrate and explain the principles of the invention. It is to be understood that the specific embodiments of the present invention are not limited thereto. Various changes and modifications may be made by those skilled in the art without departing from the scope and scope of the invention.
