Description

Method for Updating and Restoring Terminal Device Data in Device Management

technical field

The invention relates to the communication field, in particular to a method for updating and restoring terminal equipment data in equipment management.

Background technique

Mobile terminal equipment is an important part of the entire mobile operation service system. With the increasing complexity of terminal equipment functions, the possibility of terminal equipment software problems increases significantly. How to improve service quality, ensure user experience, and reduce operating costs of system equipment when solving problems has become a concern of terminal equipment manufacturers.

In the existing Mobile Alliance Device Management (OMA DM) specification, the system sets up a mechanism for configuring terminal device parameters from the server side and sending an update package to the terminal device to update the terminal device software. However, after the parameter configuration or the software update package is updated successfully, when a problem occurs logically (for example: the updated software still has errors or the updated parameters make the software unusable, etc.), how to restore to the state before the update, the prior art A method is provided:

At present, the data before the update is backed up on the server side, and when a logical error occurs, the data before the update is re-delivered to complete the data recovery.

Figure 1 is a flow chart of data backup and data update signaling in the prior art, as can be seen from the figure, the steps are as follows:

Step 1: Establish the connection between the server and the terminal device according to the OMA DM standard;

Step 2: The server sends a parameter configuration message according to the data involved in this update;

Step 3: The terminal device responds according to the obtained parameter configuration message, and uploads corresponding parameter data;

Step 4: After the server receives the uploaded data, back it up on the server side;

Step 5: The server sends the update package, and the terminal device performs the update operation after receiving it;

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 restore to the configuration before the update, refer to the prior art data recovery signaling flow chart shown in Figure 2. As can be seen from the figure, the steps are as follows:

Step 1: Establish the connection between the server and the terminal device according to the OMA DM standard;

Step 2: The terminal device notifies the server of the parameters it needs to restore by telephone, WEB or other means;

Step 3: The server issues an update package, the content of which is the relevant data backed up before the last update;

Step 4: After receiving the update package, the terminal device performs an update operation to complete recovery.

Through the above data backup and data update process, it can be seen that the data is backed up on the server side, which increases the consumption of server resources; since the data is backed up on the server side, and the original data is on the terminal device, it must be updated every time Uploading relevant data before updating increases the consumption of network resources; and transmitting data over the mobile network will increase the probability of errors.

It can be seen from the above data recovery process that since the data is backed up on the server side, the server needs to send relevant data for each recovery, which increases the consumption of network resources; transmitting data on the mobile network will increase the probability of errors ; And at present, the user cannot recover by himself, and the user can only notify the server side to cooperate with him through telephone, WEB, etc., and initiate the recovery process; if the operator finds an error, he cannot actively recover from the server side.

Contents of the invention

The invention provides a method for updating terminal equipment data in equipment management, which is used to solve the problems in the prior art that the consumption of server resources and network resources is large, and data transmission on the network is prone to errors.

The present invention also provides a method for recovering terminal device data using the backup data, which is used to solve the problem of large consumption of network resources in the prior art, error-prone data transmission on the network, and the inability of users to Recovery, the problem that the server side cannot actively recover.

The present invention adopts a method for updating terminal device data in device management. The method establishes a connection between the terminal device and a device management server (DM Server), and the DM Server sends update data to the terminal device, and the terminal device uses the update data to overwrite The data that needs to be updated at the local end; before the terminal device performs a data update operation, back up the data that needs to be updated on the terminal device.

Before backing up the data to be updated on the terminal device, the user is prompted to select the data to be backed up.

The terminal device uses a tree structure to manage data; or uses a database or data list to manage data.

If the terminal equipment adopts a tree structure to manage data, before performing the first backup, a backup node is created in the tree structure, and the node structure of all nodes in the original tree structure except the root node is created under the backup node. , back up the data that needs to be updated to the corresponding node under the backup node. The backup node may be created under the root node.

The node structure created under the backup node changes correspondingly according to the change of the node structure under the original root node.

If the terminal device uses a tree structure to manage data, backing up data before the data update operation is to create a backup node in the tree structure, and back up the data to be updated to the backup node. The backup node can be created under the node where the data needs to be updated.

Before the first backup, create a backup node under the node where the data needs to be updated. When backing up the data under the same node later, the data to be updated will be backed up to the backup node and the previous data will be overwritten; or, each time Before backing up the data under the same node, create a backup node with a version number under the node where the data needs to be updated, and back up the data that needs to be updated to the corresponding backup node.

After the update operation is completed, the terminal device reports to the DM Server whether the update operation is successful.

The present invention also adopts a method for recovering terminal device data in device management, including the following steps: determining the data that needs to be restored; extracting the restored data from the backup data of the terminal device; covering the corresponding recovery data on the terminal device current data.

The device management server (DM Server) determines the data to be recovered and sends a recovery request message to the terminal device, and the terminal device performs a recovery operation after receiving the message; or, the DMServer determines the data to be recovered, and the terminal device Submit the restored data to the device management server, and the device management server restores the data of the terminal device according to the Open Mobile Alliance Device Management (OMA DM) process; or, the user directly triggers the recovery operation on the terminal device and determines the data to be restored.

The restore request message carries restore object information, which is used to inform the terminal device of the data that needs to be restored.

After the recovery data operation is completed, a step is also included: the terminal device judges whether the recovery is successful, and sends a recovery status message to the DM Server.

If the recovery is successful, the backup data will be deleted, otherwise, the backup data will not be deleted.

The beneficial effects of the present invention are as follows: the method for updating terminal device data provided by the present invention backs up relevant data on the terminal device before updating data, without uploading the data, thereby saving server and network resources and reducing network transmission data quantity.

In the method for recovering terminal device data provided by the present invention, since the data is backed up in the terminal device, there is no need to transmit the backup data during recovery, thereby saving network resources and reducing the amount of data transmitted by the network; When there is a problem, the backup data can be called to restore it by itself. When the operator finds a problem after the update, the server can actively send a recovery request message to the terminal device to restore the data.

Detailed ways

In order to save server and network resources and reduce the amount of data transmitted over the network when updating data, the present invention backs up data that needs to be updated on the terminal side when updating terminal device data. The terminal equipment includes mobile terminal equipment and fixed terminal equipment, and the data management structure of the terminal equipment adopts a tree structure, or adopts a database or a data list to manage data. Hereinafter, the present invention will be described in detail by taking the data management structure as a tree structure as an example.

Example 1: The update process is initiated by the terminal device, and different versions of data to be updated are backed up under the same backup node. As shown in Figure 3, it is a flow chart of the steps of the inventive method, and as shown in Figure 4, it is a signaling flow chart of the inventive method, as can be seen from the above two figures, the method comprises the following specific steps:

S1. The terminal device establishes a connection with a device management server (DM Server).

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.

S2. The terminal device sends a data configuration request message to the DM Server.

After the connection is established, the user actively initiates the update process. The terminal device constructs a data configuration request message according to the content of the data that the user needs to update and the path of the node where the data is located. Then send the data configuration request message to the DM Server through the terminal device, which is used to inform the DM Server which update data to send, and make the DM Server configure the update data according to the path, so that the update when updating Data can be automatically copied to the corresponding data node.

S3. The DM Server issues 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 content of the data that the user wants to update and the path of the data, and accordingly constructs the relevant data into an update data packet and sends it to the user terminal device.

S4. Create a backup node under the data node to be updated.

FIG. 5 is a schematic diagram of a data structure before creating a backup node, and FIG. 6 is a schematic diagram of a data structure after creating a backup node. According to the data path in the sent data configuration request message, the terminal device creates a backup node for storing the data to be updated under the node where the data to be updated is located on the terminal device.

S5. 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 choose whether to back up the data to be updated, which can save time and storage space. Figure 7 is a schematic diagram of the data structure after backing up the data to be updated. It can be seen from the figure that according to the user's selection of the data to be backed up, the data to be updated 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 the data under the same node needs to be updated again, no backup node will be created, but the data to be updated will be directly backed up to the created backup node, and the previous data will be overwritten.

S6. Update data.

After the backup work is completed, the terminal device uses the update data package sent by the DM Server to update itself. After the update data package 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. It can be seen from the figure that after the update, the data to be updated is covered by the updated data.

S7. Report the update situation.

After the update operation is complete. The terminal device reports to the DM Server whether the update is successful.

The order of steps S4 and S5 and step S3 described in this embodiment can be interchanged, or steps S4 and S5 and step S3 can be performed at the same time, as long as the data to be updated is backed up before the update data operation starts to the terminal equipment, all should be within the scope of protection of the present invention.

S3. The DM Server issues update data according to the content of the received data configuration request message. (same content as Example 1)

S4. Create a backup node with a version number under the data node to be updated.

When backup is required, the terminal device creates a backup node with the current data version number under the node where the data to be updated at the local end is used to store the data backed up this time; later, if it is necessary to update the data under the same node again, Create a backup node with the current data version number and store the backup data. In this way, the subsequent data does not overwrite the previous data, which is convenient for maintenance.

S5. Back up the data to be updated to a corresponding backup node.

Before the backup, the user can determine whether the data to be updated is important, and choose whether to back up the data to be updated. After selecting, back up the data to be updated this time to the backup node with the same version number as the backup node, that is, to back up the data to be updated on the terminal device to complete the backup work. A schematic diagram of the data structure after the backup is shown in FIG. 9 .

S4. Create a backup node in the tree structure, and create a node structure of all nodes in the original tree structure except the root node under the backup node.

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

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

When the original tree structure changes, the created backup tree structure changes accordingly.

S5. At least back up the data to be updated to a corresponding node under the backup node.

Before the backup, the user can determine whether the data to be updated is important, and choose whether to back up the data to be updated. Since 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, so as to save time and space.

S6. Update data. (same content as Example 1)

S7. Report the update situation. (same content as Example 1)

Similarly, as long as the data is backed up to the terminal device before the data update operation starts, it should be within the protection scope of the present invention.

The process of updating terminal device data described in the present invention can also be initiated by the DM Server. After the connection between the terminal device and the DM Server is established, the DM Server sends a parameter configuration request message to the terminal device, and the parameter configuration request message carries a list of contents to be updated, so that the terminal device knows that this update involves content, and accordingly, the terminal device actively backs up relevant data before the update operation starts. The following process can also be used for the method of updating terminal device data initiated by the DM Server: after the connection between the terminal device and the DM Server is established, the parameter configuration request message is no longer issued, but a creation message is issued. The creation message carries a creation path, which is used to inform the terminal device where to create a backup node in its data management structure, for example: create a backup node under the node where the data to be updated is located; wait for the terminal device to create a backup node at the corresponding position After the backup node is identified and reported, DM Server sends a backup message to the terminal device, and the terminal device backs up the corresponding data to the created backup node after receiving it; after that, the data update process is carried out.

If the present invention uses a database or a data list to manage data, a corresponding data management structure is established on the device terminal. When backing up, back up the relevant data and its path into the database or data list, so that subsequent operations can be searched and called.

In the case of terminal device data update failure or failure, the above backup can be used to perform data recovery operations on the terminal device as required, and the recovery operation can be initiated by the terminal device side or by the device management server side.

The data recovery process initiated by the device management server (DM Server) is shown in Figure 12 and Figure 13, and its specific processing steps are as follows:

S1. The device management server establishes a connection with the terminal device.

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

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

After the connection is established, DM Server actively initiates the recovery process. According to the update error confirmed by the operator, when constructing the restoration request message, the data content corresponding to the error is carried in the restoration request message, so as to inform the terminal device which data needs to be restored. Afterwards, the recovery request message is sent to the user terminal equipment.

S3. Extract recovery data from the backup data.

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

If adopting the method of creating a backup node under the node where the data to be updated is located, then as shown in Figure 8 and Figure 9, the original path of the data is the upper level node of the backup node; if adopting is to create a backup tree, Or the method of creating a backup node under any node, as shown in Figure 10 and Figure 11, the original path of the data is the node path where the data needs to be restored found under the original root node.

S4. Overwrite the current data.

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

S5. Determine whether the restoration is successful, and report the restoration situation.

After the restoration operation is completed, the terminal device judges whether the restoration is successful. After the judgment result is obtained, the terminal device sends a recovery status message to the DM Server, and the recovery status message carries a code for identifying the recovery status, 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 decides 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, then a delete message is sent to the terminal equipment to inform the terminal equipment to delete the backup data. After the result shows that the recovery is successful, the terminal device can also actively delete the backed up data to save storage space. Of course, the backup data may not be deleted after the restoration is successful, so that it can be used in subsequent processes.

The steps to restore data independently by the user are as follows:

S1. When the user finds that there is a problem after the update, he can independently initiate the recovery process.

S2. Determine the data to be restored according to the found errors, extract the restored data from the backup data, and analyze the original path of the data.

S3. Overwrite the current data with the extracted data.

S4. After the restoration operation is completed, it is judged whether the restoration is successful, and if the restoration is successful, the backup data may be deleted or not.

When restoring terminal device data, the backup data can also be uploaded to the device management server, and then the device management service will restore the data of the terminal device. The processing steps are as follows:

S1. The device management server establishes a connection with the terminal device. (same content as example 1)

S2. The DM Server extracts the corresponding data and its path from the terminal device according to the content of the data to be restored.

S3. Pack the data and send it to the terminal device.

S4. The terminal device overwrites the current data with the data in the data packet.

S4. After the restoration operation is completed, it is judged whether the restoration is successful, and the restoration situation is reported. (same content as example 1)
