Description

Data sharing and data backup and recovery method

TECHNICAL FIELD The present invention relates to the field of communication device management technologies, and in particular, to a data management method for a communication device. More specifically, it relates to data sharing and data backup recovery methods. BACKGROUND A mobile terminal is an important component of an entire mobile operation service system, and along with an increasing performance of a mobile terminal, various software (refer to application software, such as game software, etc.) and firmware (refer to terminal equipment) running in the terminal device Low-level platform software) is also emerging. For mobile operators and mobile terminal manufacturers, how to implement effective management of various software and firmware running on the terminal device to ensure that the terminal device can use various software and its firmware normally, so that the user gets good. User experience, as well as improving service quality and effectively reducing equipment maintenance costs, play an extremely important role.

The existing Open Mobile Alliance (OMA) Device Management (DM) specification stipulates that terminal devices can perform parameter configuration, firmware upgrade, and software download operations through the DM server, but these are required by the terminal device. Data can only be obtained from the DM server. For example, when the DM server provides management operations such as software download, firmware update, and parameter configuration to the terminal device, the DM server sends the related data packet to the terminal device.

For example, the specific processing flow of the anti-virus software update packet sent by the DM server is shown in Figure 1. The specific implementation process is as follows (the part of the process of establishing the connection phase between the initial terminal device and the DM server is omitted).

The DM server sends a request message for obtaining the software version information to the terminal device. The DM server obtains the related software information from the management tree of the terminal device by sending a script with a Get command, as follows:

<Get>

<Item>

<Target> <LocURI>Jantivirus_data/version</LocURI></Target>

</Item>

</Get>

2. The terminal device feeds back a response message carrying its own software version information, wherein the terminal device returns the software version information to the DM server through the Results command, as follows:

<Item>

<LocU I>Jantivirus_data/version</LocURI>

</Source>

<Data>antivirus-inc/20010522b/5</Data>

</Item>

</Results>

3. The DM server selects the software update data packet corresponding to the software according to the software version information fed back by the terminal device, and sends the software update data packet to the terminal device; wherein the DM server sends the software update data packet to the terminal device through the Replace command. details as follows:

<Meta>

<Type xmlns^^syncmlimetinf^application/antivims-inc-virusdef

</Type>

</Meta>

<Item>

<LocURI>./antivirus_data</LocURI>

</Target>

</Item> </Replace>

4. The terminal device saves the software update data packet delivered by the DM server, and runs the software update data packet to upgrade and install its own anti-virus software;

5. The terminal device feeds back a success message to the DM server to indicate that the terminal device has successfully received the software update data packet.

It can be seen from the above process that in the existing OMA DM protocol, the terminal device can only passively receive data sent by the DM server, but cannot upload data to the DM server, and cannot actively download data from the DM server. In this way, the user cannot share his own data. For example, the user forwards the characteristic data on the terminal device to the friend through the DM server, thereby realizing data sharing, wherein the characteristic data here includes but is not limited to application data (such as ringtones). , screensavers and wallpapers, etc., applications (firmware, software) and configuration parameters, etc.; also can not get the data that others are willing to share, which makes it difficult to share data between different terminal devices, so that users can not get better user experience.

At the same time, in the existing OMA DM specification, the data backup and recovery processing technology of the terminal device is still only in the state of proposal. The main idea is: The terminal device will have its own data information (such as ringtone, screen saver, wallpaper, application software and parameter configuration). The data is backed up to the DM server in a tree-like storage structure to implement data backup processing of the terminal device. When the local data of the terminal device is damaged or lost, the terminal device obtains each backup data one by one from the tree-like storage structure stored by the DM server. Then, the device is restored to the terminal device, thereby implementing data recovery processing of the terminal device.

The tree storage structure on which the terminal device performs data backup and recovery processing is as shown in FIG. 2, wherein the "Backup" node and the "Restore" node in the tree storage structure are executable nodes, which can be respectively executed by Exec commands. Call execution.

The terminal device can remotely back up the data information to the DM server by executing the "Backup" node command. The specific processing procedure is as follows:

<Exec>

<Item>

<Target> <LocU I>. /Backup </LocURI> </Target>

<Data><LocURI>./Application data <LocURI></Data> </Item>

</Exec>

At the same time, the terminal device can restore the backup data from the DM server by executing the "Restore" node command. The specific processing procedure is as follows:

<Exec>

<Item>

<Target> <LocURI>./Restore </LocURI> </Target>

</Item>

</Exec>

The backup data recovery processing of the terminal device from the DM server is based on the application name (Application Name), the application manufacturer (Application Manufacture), the application version (Application Version) and the like, and the corresponding data is searched in the DM server. Restore the discovered application data to the local.

However, the existing OMA DM-based terminal device data backup and recovery method in the proposed state has a narrow application scope, and can only be applied to backup and recovery of data of the terminal device, and cannot be applied to user replacement. Data backup and recovery processing for terminal devices; At the same time, due to the weak function of the tree storage structure on which data backup and recovery processing depends, some data may not have information such as name, manufacturer and version; thus the terminal device backs up data to the DM server. After that, if you want to restore the backup data from the DM server, how to find the data with no related name, manufacturer and version information from the tree storage structure stored in the DM server for backup data recovery is more difficult. solved problem.

The following will be combined with the drawings.

Said.

First, the two device management-based data sharing methods proposed by the present invention are respectively described. The first method for data sharing based on device management is to realize mutual sharing of data between terminal devices by relaying and forwarding shared data by the DM server; the second method for data sharing based on device management is adopted by the DM server. The address information of the location where the shared data is stored is forwarded to share data between the terminal devices. Then, the present invention is directed to the above two data sharing methods, and accordingly, a data backup and recovery method based on device management is proposed.

The above-mentioned technical solutions of the present invention need to establish a unified data storage structure in each terminal device. FIG. 3 shows a subtree tree storage structure stored in the terminal device according to the present invention, and FIG. 3 is referred to. Mainly to solve the problem of different data organization structures between different terminal devices, the storage structure strategy is used to facilitate the DM server to find. By creating a shared subtree as shown in the figure on the management tree of each terminal device, the data to be sent (including shared data, address information of the location where the shared data is stored, pre-backed up data information, or backup data information) The address information of the storage location, etc.) is uniformly stored in the shared subtree, and the data to be received (including the shared data, the address information of the location where the shared data is stored, the restored backup data information, or the address information of the location where the backup data information is stored, etc., etc.) ) is also stored in the shared subtree.

The specific description of the shared subtree is as follows (to store the corresponding shared data as an example, the storage of other data information is the same or similar to the shared data;): <internal node>

The internal node is the starting node of the shared subtree and contains shared data information, allowed operating permission descriptions, and some operational commands. The internal node can be placed anywhere under the root node of the device management tree (DM tree). It is a permanent node (a permanent node refers to a node that the DM server cannot delete), which can be generated by the device manufacturer or by other management parties. Need to be produced. It is described in the Device Description Framework (DDF, Device Description Framework) document in its specific location on the DM tree.

/<X>

This node is the parent node of the shared data information, and the user will be willing to share the shared data. Placed under this node, the shared data obtained from other terminal devices is also placed under this node,

DMAgent (DM Agent is an application running on the terminal device, which is responsible for the device management service, interacts with the DM server, interprets the execution device management command, as long as the terminal supporting the DM service has DMAgent) or the user organizes the use of the node. data.

/<X >/<Name>

This node is used to describe the name of the shared data.

/<X >/<Description>

The node is used to store description information of the shared data.

/<X>/<U I>

The node is used to store the URI of the shared data on the DM tree. When the shared data is the node data on the DM tree, only the URI of the shared data is stored, thereby avoiding wasting storage space; and when the shared data is not in the DM tree, the node is used. The <Data> node below stores the actual shared data.

/<X>/<Data>

This node is used to store the actual shared data, that is, when it is sent, it stores shared data that is not on the DM tree, and also stores the received shared data.

/<X >/<Type>

This node is used to describe the type of shared data, which is convenient for recipients to identify.

/<X>/<Size>

This node is used to describe the size of the shared data.

/<X>/<Ext> Occurrence format access

One Or Zero Node Get, Replace

This node is used to store other relevant information about the shared data.

/<Read Allowed>

This node is used to describe a terminal device that allows reading of a shared subtree, that is, a terminal device that allows acquisition of shared data from the shared subtree.

/<Read Allowed>/<IMSI>

The node is used to describe the IMSI (International Mobile Subscriber Identit) information of the terminal device that is allowed to obtain the information of the shared subtree. The IMSI included in the node may be added, modified, and deleted by the user.

/<Write Allowed>

This node is used to describe a terminal device that allows writing of a shared subtree, that is, a terminal device that allows transmission of shared data to the shared subtree.

/<Write Allowed>/<IMSI>

The node is used to describe the IMSI information of the terminal device that allows the shared data to be sent to the shared subtree. The IMSI included in the node can be added, modified, and deleted by the user.

/<Operations>

This node is used to describe the parent node of the related operations on the shared subtree. The node exists as a collection of related operations for sharing data. It is equivalent to a container. It is followed by some related operation commands.

/< Operations >/<Upload>

This node can be used by the Exec command (the Exec command is a command in the DM protocol. Execute the executable node. Since Upload and Download are not existing commands in the DM protocol, they must be called by Exec to initiate the upload operation and upload the shared data to the DM server. Upload can call other protocols to complete the upload operation. The DM server can be notified to extract.

/< Operations >/<Download >

The node can be initiated by the Exec command (this Exec command can be initiated by the DM server or by the terminal device, but all executed by the terminal device) to initiate the download operation, that is, download the shared data from the DM server to the shared subtree. Download can call other protocols (such as OMA Download protocol) to complete the download operation, or notify the DM server to deliver.

/< Operations >/<Ext>

This node is used as a reservation for future extensions and can be used to describe other related operations on the shared subtree.

/<Ext>

This node is used to store other relevant information of the shared subtree, which is reserved for future extensions. The following describes an invention solution for relaying shared data by a DM server to implement data sharing between terminal devices. Referring to FIG. 4, the present invention implements data between terminal devices by relaying and forwarding shared data by a DM server. Schematic diagram of the main implementation process of sharing, the main implementation process is as follows:

In step S01, a session connection is established between the DM server and the same terminal device (the process of establishing the session connection phase is clearly defined in the OMA DM specification, which is not described here), where the connection establishment phase includes the DM server source. The process of authorization authentication by the terminal device, which will be explained later.

Step S02, the source terminal device participating in the data sharing reports the shared data to the DM server; the process may report the shared data to the DM server by the source terminal device actively; The source terminal device may request the source terminal device to report the shared data, and the source terminal device reports the shared data in response to the request of the DM server.

Step S03, the DM server establishes a session connection with the destination terminal device (the process of establishing the session connection phase is clearly defined in the OMA DM specification, and is not described here), wherein the establishment connection phase includes the DM server for the purpose. The process of authorization authentication by the terminal device, which will be explained later.

Step S04: The DM server sends the shared data reported by the source terminal device to the corresponding destination terminal device according to the source terminal device information and the destination terminal device information that participate in the data sharing. The process may be performed by the DM server directly sending the shared data to the destination terminal device. The destination terminal device may also request the DM server, and the DM server downloads the shared data to the destination terminal device in response to the request.

The source terminal device information and the destination terminal device information that notify the DM server to participate in data sharing can be implemented in the following two ways:

(1) External mode

That is, the user notifies the source terminal device information and the destination terminal device information participating in the data sharing by means of an external notification mode (ie, a method other than the DM protocol, such as the user calling the operator's customer service center, or the user logging in to the Web site). To the DM server, that is, to inform the DM server from which source terminal device to take the shared data, and then to which destination terminal device (the data transmission mode may also be that the source terminal device uploads the shared data to the DM server, and the destination terminal device downloads from the DM server. ).

(2) DM protocol command mode

That is, the source terminal device notifies the DM server of the source terminal device information and the destination terminal device information that participate in the data sharing in the shared data. That is, the source terminal device information or the destination terminal device information is carried in the shared data, and the DM server is notified by the DM protocol command, the destination terminal device to which the shared data is to be transmitted, or from which source terminal device the shared data is to be acquired.

Since the shared data is transited through the DM server, the address of the DM server is processed into a direct address in the shared data, and the address of the source terminal device or the destination terminal device is processed into an indirect address. And because the current OMA DM protocol cannot support the data bearer indirect address for reporting

DM server, so you need to extend a tag <Indirect> that represents an indirect address, the tag

<Indirect> is set to be used in the shared data initiated by the source terminal device or the destination terminal device. It should be used together with the existing tag <8011«^> or 3⁄4 61>, and the <80111^> is used together to indicate the source terminal device address as the indirect. The address, used in conjunction with <Ding & 1^1>, represents the destination terminal device address as an indirect address.

For example, in the following command:

<Target> <LocURI> http://www.syncml.org/mgmt-server </LocURI> </Target>

</SyncHdr>

...

<Exec>

<Item>

<Target> <LocURI>./Operations/Upload</LocURI>

</Target>

</Item>

</Indirect>

</Target>

</Exec>

</SyncBody>

In the above command program, in the <8 11 (;13⁄41'> message header container, <Source>/<LocURI> is the international mobile device identifier IMEI of the source terminal device, <Target>/<LocURI> is directly Address, which is the address information of the DM server. In <8 1108 (^> message body container, <Exec>/<Item>/<Target> is an executable command node, indicating upload, and

Indirect address information, that is, the destination terminal device IMSI. Therefore, the command program can be used to notify the DM server that the shared data uploaded to the DM server is forwarded to the destination terminal device.

What needs to be explained here is: <1^(;1;1^> of the tag <Source>† identifies the IMEI of the terminal device, and 3⁄4 61:>/<111 (1 <^^ in the ^^( ;11[1> provides the user's IMSI; because the user is more familiar with the IMSI, the DM server needs to associate the IMSI of the user with the IMEI of the terminal device held by the user. Through the correspondence, the DM server is When the shared data is forwarded to the destination terminal device, the address IMEI of the destination terminal device is carried in the shared data.

In the above example, <Exec>/<Upload> <Target>/<Indirect>/<LoclI I> is used together to indicate that the shared data is to be uploaded to the destination terminal device; and if the destination terminal device is to be downloaded from the source terminal device, For data, <Exec>/<Download> should be used together with <8011^^>/<1]1(1 601;>/< 0001^>.

Therefore, the terminal device information of the source terminal device or the destination terminal device participating in the data sharing may be an International Mobile Station Equipment Identity (IMEI) of the terminal device, or may be an International Mobile Subscriber Identity (IMSI) of the user to which the terminal device belongs. ).

In the above step S01, the DM server needs to authenticate whether the source terminal device can share the shared data to the destination terminal device, and the authentication process is:

Providing, in the source terminal device, a destination terminal device identifier list capable of reading the shared data provided by the source terminal device; wherein the terminal device identifier may be an IMSI of the user to which the terminal device belongs;

The DM server reads a list of destination terminal device identifiers set in the source terminal device (which may be an IMSI list of the destination terminal device);

When the destination terminal device identifier (the IMSI of the destination terminal device) participating in the data sharing is in the destination terminal device identification list (the IMSI list of the destination terminal device), the source terminal device is allowed to share the shared data to the destination terminal device.

At the same time, in the above step S03, the DM server also needs to authenticate whether the destination terminal device can share the shared data provided by the source terminal device, and the authentication process is:

Setting a source terminal device identifier list (which may be an IMSI list of the source terminal device) of the provider of the shared data that can be written to the destination terminal device in the destination terminal device;

The DM server reads the source terminal device identifier list set in the destination terminal device (source terminal) The IMSI list of devices); and

When the source terminal device identification (IMSI of the source terminal device) participating in the data sharing is in the source terminal device identification list (the IMSI list of the source terminal device), the destination terminal device is allowed to share the shared number provided by the source terminal device.

That is, for security reasons, the DM server needs to perform authentication authentication on both the transmitting and receiving sides of the shared data respectively; in step S01, the DM server needs to authenticate whether the source terminal device allows the shared data to be sent to the destination terminal device, and the authentication is performed. The process is to see if the IMSI of the destination terminal device is in the <Read Allowed> list of the shared subtree stored by the source terminal device. Similarly, in step S03, the DM server needs to authenticate whether the destination terminal device is allowed to receive the shared data from the source terminal device, and the authentication process is to see whether the IMSI of the source terminal device is in the shared subtree stored by the destination terminal device. ^'^ Allowed> (Allow write) in the <1^^1> list.

Fig. 5 is a schematic diagram showing the process of authenticating a terminal device by a DM server in the present invention, with reference to Fig. 5. The specific processing of its authentication is as follows:

Step S11, the DM server notifies the terminal device through the Notification message, requesting to establish a connection;

Step S12: The terminal device responds to the request, and establishes an initial connection with the DM server (processed by the DM Agent agent in the terminal device);

Step S13: The DM server queries the terminal device for the read and write permission information set in the shared subtree stored by the terminal device. The following command can be used to query the permission permission information set in the shared subtree stored by the terminal device:

For example, use the Get command:

<Get>

<Item>

<LocU I>./Read Allowed/IMSK/LocURI> </Target>

</Item>

</Get> Step S14: The DM Agent in the terminal device feeds back the read and write permission information stored in the subtree to the DM server. For example, the following command can be used to feedback the read permission information stored in the shared subtree to the DM server:

<Item>

<LocU I>./Read Allowed/IMSK/LocURI>

</Source>

<Datn>> *********** 〉

</Item>

</Results>

Step S15: The DM server determines, according to the obtained read/write permission information of the terminal device, whether the IMSI of the shared data receiver is in the list of permitted read data of the shared data sender, if yes, indicating The receiving party can obtain the shared data from the terminal device. (Similarly, the DM server can also determine whether the IMSI of the shared data sender is allowed to write in the shared data receiver according to the read and write permission information allowed by the obtained terminal device. <^1- Allowed^ <IMSI> in the list, if it indicates that the sender can share data to the receiver), the DM server can continue forwarding operations; otherwise, the DM server will not be able to obtain shared data from the sender;

The process in which the source terminal device reports the shared data to the DM server in the foregoing step S2 can be implemented in two ways, as follows:

FIG. 6 is a schematic diagram of a first implementation process of reporting shared data from a source terminal device to a DM server according to the present invention. Referring to FIG. 6, the specific implementation process is as follows:

Step S21: The DM server sends a request message for requesting the source terminal device to report the shared data to the source terminal device, that is, the DM server requests the source terminal device to use the Get command. Data

Step S22: The source terminal device reports the shared data to the DM server in response to the received request message, that is, the source terminal device returns the shared data to the DM server by using the Results command.

FIG. 7 is a schematic diagram of a second implementation process of reporting shared data from a source terminal device to a DM server according to the present invention. Referring to FIG. 7, the specific implementation process is as follows:

Step S31, setting an active upload executable command in the source terminal device (such as an executable command Upload in the shared subtree stored in the terminal device); the source terminal device shares the data by running an active upload executable command uploaded by itself. Reported to the DM server;

Step S32: After receiving the shared data reported by the source terminal device, the DM server feeds back the successful receiving message to the source terminal device.

At the same time, the process of forwarding the shared data to the destination terminal device by the DM server in the above step S4 can also be implemented in two ways, as follows:

FIG. 8 is a schematic diagram of a first implementation process of the DM server transmitting the shared data to the destination terminal device in the present invention. Referring to FIG. 8, the specific implementation process is as follows:

Step S41: The DM server directly delivers the shared data to the destination terminal device by using the Replace command.

Step S42: After receiving the shared data, the destination terminal device feeds back the successfully received message to the DM server.

FIG. 9 is a schematic diagram of a second implementation process of the DM server transmitting the shared data to the destination terminal device in the present invention. Referring to FIG. 9, the specific implementation process is as follows:

Step S51, setting an active download executable command (such as an executable command Download in the shared subtree stored in the terminal device) in the destination terminal device; the destination terminal device downloads the executable command to the DM server by running the set active download command Request to download shared data;

Step S52: The DM server sends the shared data to the destination terminal device in response to the received request.

Since the data organization form of each terminal device may be inconsistent, it is likely that the transmitting and receiving Han cannot recognize the shared data of the other party, and therefore the shared data needs to be parsed. Data parsing can be done in the following ways: (1) DM server resolution

The DM server obtains the shared data from the source terminal device, parses the shared data according to the manufacturer model and the data type description of the source terminal device, and converts the shared data into a destination terminal device according to the manufacturer model of the destination terminal device. data.

(2) Target terminal device resolution

The destination terminal device parses the received shared data, which may be completed by the DM Agent, or the user may organize the usage data.

The DM server can set a policy for saving and deleting shared data, as follows:

(a) save

The DM server obtains the shared data from the source terminal device, saves the acquired shared data, and then delivers the shared data to the destination terminal device.

( b ) not saved

The DM server does not store the shared data, but provides a channel from the source terminal device to the destination terminal device. The DM server receives the shared data from the source terminal device and delivers the shared data to the destination terminal device.

(c) delete

After the DM server delivers the shared data to the destination terminal device, the saved shared data is deleted to avoid wasting storage space.

(d) not delete

After the DM server delivers the shared data to the corresponding destination terminal device, the saved shared data is not deleted, and the uploader is marked for the shared data. The next time the destination terminal device requests the shared data, the DM server does not need to re-source from the source. The terminal device requests to share the data, and directly sends the saved shared data to the destination terminal device.

The following describes the invention for realizing the backup and recovery of the terminal device data by using the backup data information of the DM server to store the terminal device. According to the data backup and recovery method proposed by the present invention, the user can put the data information on the terminal device into its own sharer. The tree is then uploaded to the DM server for storage. When the data on the terminal device is damaged or lost, or the user replaces the terminal device, the previously saved data information can be downloaded from the DM server, thus realizing the backup and recovery of the data. In the backup and recovery process of data information, users can be more The terminal equipment is changed, and is not limited to replacing the terminal equipment of the same brand, and may be terminal equipment of different brands and different models.

In the application scenario where the backup data information is restored, the user can set <^^1^11(^6(1> and <1^&(1 Allowed>) in the shared subtree as their own, which is equivalent to Only the data information is shared with itself, thus avoiding the danger of others stealing data information. After the pre-backup data information is uploaded to the DM server, the user can delete the data information stored in the shared subtree to save storage on the terminal device. In this application scenario, the DM server needs to associate the data information uploaded by the user with the IMSI of the user to which the terminal device uploading the data information, and store it in the form of a directory, so that the user can download from the DM server when the user downloads and restores. Get the backup data information in this storage directory.
