Detailed ways

In the embodiment of the present invention, for the user side, the stored DDF information or the storage location of the DDF information is sent, and the DDF information or the storage location of the DDF information is stored in the terminal device; Information or the information of the storage location of the DDF information, and obtain the DDF information from it, or obtain the DDF information from the corresponding storage location. The specific implementation method can be:

For user side

The stored DDF information or the storage location of the DDF information is sent, and the DDF information or the storage location of the DDF information is stored in the terminal device.

Wherein, the operation of saving the DDF information or the storage location of the DDF information in the terminal device can be completed by the manufacturer before the terminal device leaves the factory, or can be completed by the terminal device when the function is upgraded or new hardware is added. The storage location of the DDF information can be path information such as URI (Uniform Resource Identifier, Uniform Resource Identifier) or URL (Uniform Resource Locator, Uniform Resource Locator), and the DDF information is stored in a certain position in the terminal or in the network. For example, when the terminal performs a function upgrade, the DDF information corresponding to the function will be generated in the terminal, and the storage location of the DDF information will be saved in the terminal device (of course, the generated DDF information corresponding to the function can also be stored in the terminal device. The information is directly stored in the terminal device so that the DM server can obtain it directly without being guided by the corresponding path information); for another example, when the terminal adds hardware, the storage location of the DDF information corresponding to the hardware function is stored in the terminal In the device, the DDF information corresponding to the hardware function is stored somewhere in the network by the manufacturer of the hardware.

In this embodiment of the present invention, the saving of the DDF information or the storage location of the DDF information in the terminal device may be specifically saving the DDF information or the storage location of the DDF information in the DM management tree of the terminal device, and each The DDF information or the storage location of the DDF information is stored in a leaf node as a node value. The DDF information or the location where the DDF information is stored in the DM management tree can be implemented in multiple ways, one of which can be to set in the DM terminal management tree specially used to store all DDF related information ( Such as DDF information, DDF information storage location, etc.), each DDF information or DDF information storage location is respectively stored in the leaf node under the node dedicated to storing DDF related information.

In order to enable the DM server to quickly obtain the required DDF information, the MOI (management object identifier) information corresponding to the DDF information may also be stored in the location where the DDF information or the storage location of the DDF information is located during the above process, For example, the MOI information corresponding to the DDF information is stored as a node value in another leaf node under the DDF information or the storage location of the DDF information (the leaf node storing the MOI information is the same as the leaf node storing the MOI information) The DDF information corresponding to the information or the leaf node of the storage location of the DDF information is in a parallel position in the management tree, and corresponds to). The MOI information corresponding to the DDF information refers to the MOI information of the MO (eg function) corresponding to the DDF information. Wherein, if the DDF information does not contain the corresponding MOI information, the corresponding MOI information must be configured at the location where the DDF information or the DDF information is stored, otherwise, the corresponding MOI information can be optionally configured at the location.

The location where the DDF information or the storage location of the DDF information is located is a node, and the position and structure of the node in the DM management tree can be implemented in multiple ways. A specific structure of the node can be, if the node contains only the DDF information or the storage location of the DDF information, then save the DDF information or the storage location of the DDF information as the node value; if the node also contains the corresponding MOI information of the DDF information, then the node also contains The DDF leaf node and the MOI leaf node, the DDF information or the storage location of the DDF information is saved as the value of the DDF leaf node, and the corresponding MOI information is saved as the value of the MOI leaf node. In order to realize the operation of the DM server on the node storing DDF-related information in order to obtain DDF information, it is necessary to inform the DM server of the position of the node in the DM management tree in advance. This operation can be performed by the manufacturer of the terminal device or by the terminal device execution.

The method of sending the saved DDF information or the storage location of the DDF information described in the above-mentioned embodiments of the present invention may specifically be that the terminal device actively sends the DDF information or the storage location of the DDF information, wherein the DDF information or There are one or more storage locations of the DDF information; or, after receiving the operation command, the terminal device sends the DDF information or the storage location of the DDF information according to the operation command. At this time, the terminal device can also send the MOI information corresponding to the DDF information at the same time. The specific execution process is that the terminal device judges whether the MOI information has been included in the sent DDF information, and if so, the MOI information may not be sent. Otherwise, the MOI information must be sent.

Wherein, if the terminal device actively sends information, the information may be all DDF information stored in the terminal device and the storage location of the DDF information, or it may be added, deleted or updated when the function of the terminal device is upgraded or new hardware is added, etc. DDF information and the storage location of DDF information;

If the terminal device sends the DDF information or the storage location of the DDF information according to the operation command after receiving the operation command, the specific implementation method includes: if the operation command is a command to obtain all DDF information, sending All the saved DDF information or the storage location of the DDF information; or, if the operation command is a command to obtain the specified multiple DDF information, send the specified multiple DDF information or the storage location of the DDF information; or, if The operation command is a command to obtain the DDF information corresponding to the specified MOI information, then according to the MOI information in the command, it is searched whether there is corresponding DDF information or the storage location of the DDF information, and if it exists, the DDF information or The storage location of the DDF information, otherwise, an error message is fed back; or, if the operation command is a command to obtain new DDF information, then according to the command to find whether there is new DDF information or a storage location of the DDF information, if exists, then send the new DDF information or the storage location of the DDF information, otherwise, feed back a message that there is no new DDF information, and the new DDF information refers to the information added, deleted or updated after the terminal device sent the message last time. DDF information.

In the above process, if the terminal device actively reports information, it may report one or more DDF information at one time, or the storage location of the DDF information and the corresponding MOI information. For example, report all DDF-related information in the terminal device to the DM server at one time, or report multiple added, deleted or updated DDF-related information to the DM server when the terminal device performs function upgrades, adds new hardware, etc.; If the terminal device feeds back DDF-related information according to the received operation command, it may feed back one or more pieces of DDF information or storage locations of DDF information and corresponding MOI information at a time according to the operation command. Among them, if multiple DDF information or storage locations of DDF information are fed back, the terminal device also needs to judge whether each DDF information contains corresponding MOI information, and for DDF information that does not contain corresponding MOI information, it also needs to feed back its corresponding MOI information at the same time. MOI information.

For the network side

Receive the information sent by the terminal device; then, obtain the DDF information from the information sent by the terminal device, or obtain the storage location of the DDF information, and obtain the DDF information according to the storage location. The above operations may be specifically completed by the DM server.

In the embodiment of the present invention, before the step of receiving the information sent by the terminal, an operation command may also be sent to the terminal device, and the operation command may specifically include a command to obtain all DDF information; or, obtain a specified number of DDFs information; or, a command to obtain DDF information corresponding to the specified MOI information; or, a command to obtain new DDF information.

The specific implementation manner of the embodiment of the present invention in the actual application process will be described in detail below with reference to the accompanying drawings.

Application Example 1

This application embodiment will describe in detail the implementation manner of saving DDF information or a storage location of DDF information in a terminal device.

The operation of saving the DDF information or the storage location of the DDF information in the terminal device can be performed by the manufacturer, that is, the manufacturer presets some DDF information on the DM management tree of the terminal device before the terminal device leaves the factory, or the terminal device can also Execution, that is, in the case of function upgrade or new hardware addition, the terminal device will generate, delete or update DDF information and add it to its DM management tree.

The saving of the DDF information or the storage location of the DDF information on the DM management tree of the terminal device may specifically be accomplished by instantiating the node x under the DDFNode reserved for saving the information in the DM management tree. In the x node shown in Figure 2, "x" indicates that this node has not been instantiated, and "*" indicates that this node can appear 0 or more times, that is, there can be no such node, or there can be multiple such nodes in parallel node. Save the DDF information or the storage location information of the DDF information by instantiating the x node, as shown in Figure 3, wherein the node name of each node is marked in the figure, which is respectively DDF0, DDF1, DDF2 and DDF3, and each The node value of each node is a DDF information. For example, the value of node DDF0 is the DDF information of all basic functions on the terminal management tree at the factory, and the values of nodes DDF1 and DDF2 are DM Account (DM account) management object and SCOMO (Software Component Management Object, the DDF information of the software component management object), the value of the node DDF3 is the DDF information of the Function3 function. The format of the node value may be XML (eXtensible Markup Language, Extensible Markup Language) format. Wherein, the storage location of the DDF information may be path information such as URI (Uniform Resource Identifier, Uniform Resource Identifier) or URL (Uniform Resource Locator, Uniform Resource Locator), and the DDF information is stored in a terminal or in a network. Location. For example, when the terminal performs a function upgrade, the DDF information corresponding to the function will be generated in the terminal, and the storage location of the DDF information will be saved in the terminal device (of course, the generated DDF information corresponding to the function can also be stored in the terminal device. The information is directly stored in the terminal device so that the DM server can obtain it directly without being guided by the corresponding path information); for another example, when the terminal adds hardware, the storage location of the DDF information corresponding to the hardware function is stored in the terminal device In , the DDF information corresponding to the hardware function is stored somewhere in the network by the manufacturer of the hardware.

The position of the node storing the DDF information or the storage location of the DDF information in the management tree can be implemented in various ways, for example, a storage location dedicated to storing the DDF information or the DDF information can be set in the DM management tree and corresponding MOI information, the node may be called a DDFNode node. Taking the management tree structure shown in Figure 4 and Figure 5 as an example, instantiate the x node under the path ./DevDetail/Ext/DDFNode in Figure 4 to save DDF information or the storage location of DDF information, as shown in Figure 5 As shown, all DDF information or the storage location of DDF information is placed under a node named DDFNode, and the node values of nodes 0 to 3 are different DDF information or storage locations of DDF information. When a terminal device adds a new function, Nodes 4 and 5 can be added to store the generated DDF information or the storage location of the DDF information. It should be pointed out that the path in the above examples is not a limited path, and it can be other paths in actual applications, but it is necessary to let the server know the storage location of the DDFNode (the upper node of the DDF node) in advance, for example, let the server know the following from the manufacturer information:

<MgmtTree>

<VerDTD>1.2</VerDTD>

<Node>

<NodeName>DevDetail</NodeName> <! --The node name is DevDetail-->

<Path>.</Path>

...

<Node>

<NodeName>Ext</NodeName><! --Ext child node in DevDetail -->

...

<Node>

<NodeName>DDFNode</NodeName><! --DDFNode child node in Ext -->

<DFProperties>

<AccessType> <Get/></AccessType><! -- Access type to DDFNode -->

<DFFormat><node/></DFFormat><! --DDFNode node format -->

<Occurrence><ZeroOrOne/></Occurrence><! --Number of occurrences of DDFNode -->

<Occurrence><ZeroOrMore/></Occurrence><! --Number of occurrences of x nodes -->

...

</DFProperties>

</Node>

</Node>

...

</Node>

...

</Node>

</MgmtTree>

The above information describes the structure and attributes of the DevDetail (device details) management object. In the description, the position of the DDFNode node is given through the hierarchical structure, and its own structure is given, that is, the DDFNode node includes the <NodeName/> node, which Indicates that there is an x node under the DDFNode node, where the terminal can add DDF information of new functions or the storage location of DDF information, and its Occurrence (number of occurrences) is ZeroOrMore (0 or more). After learning the above information, the DM server can understand the location and attributes of the DDFNode node stored in the terminal device, and then manage the node.

In order to enable the DM server to quickly obtain the required DDF information, this application embodiment can also set the corresponding relationship between MOI and DDF in the DM management tree. As shown in Figure 6, the DDF information corresponding to the MO or the storage location of the DDF information and the MOI of the MO are respectively stored in the DDF sub-node and the MOI sub-node of the same node, that is, the parallel DDF node corresponds to the MOI node (hereinafter same). After the node x is instantiated, as shown in Figure 7, the DDFNode node contains several child nodes (each child node represents a terminal management tree or a function (such as MO), etc.) (nodes 0 to 3), and each child node represents a MO A node contains a DDF node and an MOI node, the value of the DDF node is the DDF information corresponding to the MO or the storage location of the DDF information, and the value of the MOI node is the MOI information of the MO. In this way, the terminal or the DM server can search for the corresponding DDF information or the storage location of the DDF information according to the MOI information.

Application Example 2

In this application embodiment, the process of obtaining DDF information by the DM server is described in detail by taking the situation when the terminal equipment leaves the factory as an example.

As shown in Figure 8, it is assumed that the DDF information of some functions has been preset on the management tree after the terminal equipment leaves the factory, specifically including the DDF information of the DM management tree and the DDF information of SCOMO, where the DDF information of the terminal management tree is stored in the DDFNode node On the lower node 0; the DDF information of SCOMO is stored on the child node DDF node of node 1, and its MOI information is stored on another child node MOI node. The server obtains the position of the DDFNode node in the management tree in advance. The specific process of obtaining DDF information may include:

Step 21, the DM server issues a command to obtain all DDFs;

Step 22, after receiving the command, the terminal device feeds back the node value of node 0 and the DDF node value under node 1 to the DM server, the node value of node 0 is the DDF information of the DM management tree, and the node The DDF node value under 1 is the DDF information of SCOMO;

Step 23: After receiving the node value, the server analyzes the node value to learn the structure and attributes of the DM management tree of the terminal device and the SCOMO management object.

In this application embodiment, if the DDF information does not include MOI information, the DM server also needs to obtain the MOI information corresponding to the DDF information, specifically, the MOI node value can be obtained through the acquisition command sent (for example, in this example MOI node value under node 1), in addition, if the corresponding MOI information is included in the DDF information, the DM server can also extract the MOI information from the obtained DDF information. In this example, the DM server can obtain the MOI information from the obtained 1 node The MOI information is extracted from the DDF node value, for example, urn:oma:mo:oma-scomo:1.0 is extracted, and it is known that this MO is version 1.0 of the software component management object. After the DM server obtains the required DDF information, it can manage the terminal equipment accordingly.

In addition, in the application embodiment of the present invention, the terminal device can also actively send DDF information to the DM server. The specific process can be that the terminal device first sends a session request message to the DM server. After receiving the message that the DM server agrees to the session request, the terminal The device sends the DDF information stored in the DM management tree to the DM server.

Application Example Three

In this application embodiment, the situation that the DM server obtains the DDF information corresponding to the MOI information from the terminal device by giving the MOI information will be described in detail.

Assuming that the terminal device performs a function upgrade on the basis of the situation described in the second embodiment of the application, and adds a new function called LAWMO, a DDF information corresponding to LAWMO will be generated on the terminal device at this time, or the DDF information corresponding to the LAWMO function will be generated by the terminal device. The operator informs the terminal device of the storage location of the DDF information corresponding to the LAWMO in the network, and the terminal device saves the DDF information or the storage location of the DDF information under the DDFNode node under the DM management tree, and the DDFNode The structure is shown in Figure 9, wherein node 2 is the LAWMO node, and node 2 contains a DDF node and an MOI node, the value of the DDF node is the DDF information corresponding to LAWMO, and the value of the MOI node is the value of LAWMO MOI information.

The newly added DDF information may be actively reported to the DM server by the terminal device, or acquired by the DM server through an operation command.

Wherein, if the terminal device actively reports the DDF information, the specific execution process may be that the terminal device initiates a session request message to the DM server; after successfully establishing a session link with the DM server, the DDF node value is sent to the DM server , if the DDF information does not contain the corresponding MOI information, the MOI node value needs to be sent at the same time; the DM server receives the information, and obtains the DDF information or the storage location of the DDF information from the information, If the DM server acquires the storage location of the DDF information, the DDF information is acquired according to the storage location. The information sent by the terminal device may be, but not limited to, the following code segment:

<Add>

<CmdID>3</CmdID>

<Item>

<Source><LocURI>./....../DDFNode/2/DDF</LocURI></Source>

<! --The above is the storage path of the LAWMO DDF value-->

...

<Data><! --Here is the DDF value of LAWMO--></Data>

</Item>

<Item>

<Source><LocURI>./....../DDFNode/2/MOI</LocURI></Source>

<! --The above is the storage path of LAWMO MOI-->

...

<Data>"urn:oma:mo:oma-lawmo:1.0"</Data>

<! --The above is the MOI value of LAWMO-->

</Item>

</Add>

The above code segment includes the DDF node value and the MOI node value. If the DDF information already includes MOI information, the code segment may not include the MOI node value.

Of course, the terminal device may also report multiple newly added DDF node values. In addition, in addition to the newly added DDF node value, the terminal device can also report the updated and deleted DDF node value, and optionally report the corresponding MOI node value.

If the DM server sends an operation command to the terminal device, and the terminal device sends the DDF node value to the DM server according to the operation command, then different operation commands can be sent to the terminal device, so as to obtain all The required DDF information, the specific execution process can be:

method one

The operation command is an operation command for obtaining the DDF information corresponding to the specified MOI information, and the terminal device finds the corresponding MOI node in the DM management tree according to the MOI information in the operation command; then the DDF node corresponding to the MOI node The value is reported to the DM server; if the terminal device does not find the DDF node value, an error message is fed back to the DM server, indicating that there is no DDF information corresponding to the MOI information.

If the DDF information is acquired in this mode one, the structure of the DDFNode node in the terminal device DM management tree is shown in Figure 10, wherein the Operations node includes a GetDDF node and an MOI node, and the GetDDF node is an executable node. The DM server operates the node through commands to obtain the required DDF information. The DM server can use an Exec (execution) command, a Replace (replacement) command, an Alert (alert) command, etc. to operate on the DDFNode node.

Among them, if the DM server uses the Exec command to operate this node, its operation command can be but not limited to the following code segment:

<Exec>

<CmdID>3</CmdID>

<Item>

<Target>

<LocURI>./.../DDFNode/Operations/GetDDF</LocURI>

<! --The above is the path of the GetDDF operation that needs to be executed -->

</Target>

<Data>"urn:oma:mo:oma-lawmo:1.0"</Data>

<! --The above is the MOI of LAWMO whose DDF value needs to be obtained-->

</Item>

</Exec>

The command contains the MOI as urn:oma:mo:oma-lawmo:1.0 as the input data when executing the GetDDF operation.

If the DM server uses the Replace command, the Replace command sends the MOI information to the MOI node under the Operations node, and then uses the Exec command to operate the GetDDF node to obtain the required DDF information.

If the DM server uses the Alert command, the Alert command includes MOI information, and an identifier for obtaining DDF (the Alert command notifies the terminal device through the identifier that the DM server needs to obtain the DDF information corresponding to the MOI information), according to the MOI information and the GetDDF node that wants to perform the GetDDF identification operation to obtain the required DDF information.

After receiving the operation command (which can be an Exec command, a Replace command or an Alert command, etc.) sent by the above-mentioned DM server, the terminal device executes the GetDDF operation according to the MOI information contained in the command, and feeds back the DDF information corresponding to LAWMO to the DM server. This operation can be implemented, but not limited to, by executing the following code segment:

<Status>

<MsgRef>1</MsgRef><CmdRef>3</CmdRef>

<CmdID>4</CmdID>

<Cmd>Exec</Cmd>

<! -- The Exec description above is the reply to the Exec command -->

<TargetRef>./.../DDFNode/GetDDF</TargetRef>

<! --The above path description is the reply to the GetDDF operation -->

 <Data>200</Data><! --Exec OK--><! --Exec command executed successfully -->

<Item>

<Source>

<LocURI>./....../DDFNode/2/DDF</LocURI>

<! --The above path is the storage path of the feedback DDF -->

</Source>

...

<Data><! --Feedback the DDF value of LAWMO here--></Data>

</Item>

</Status>

way two

The operation command is an operation command for obtaining new DDF information, and the terminal device searches the DM management tree according to the operation command to see if there is a node value storing the new DDF information, and if so, reports the DDF node value to the DM server , otherwise feed back a message that there is no new DDF information to the DM server. In this application embodiment, the new DDF information is the DDF information corresponding to the new function LAWMO. Of course, in the actual application process, the new DDF information It may also refer to the DDF information added, deleted or updated by the terminal device after the DDF information was reported last time.

If the second method is used to obtain DDF information, the structure of the DDFNode node in the DM management tree of the terminal device is shown in Figure 11. Among them, the SyncDDF node is an executable node, which means that the terminal device feeds back to the DM server all Feedback DDF information.

The operation command sent by the alleged DM server can be implemented, but not limited to, by executing the following code segment:

<Exec>

<CmdID>3</CmdID>

<Item>

<Target>

<LocURI>./.../DDFNode/Operations/SyncDDF</LocURI>

<! --The above is the path of the SyncDDF operation that needs to be performed -->

</Target>

</Item>

</Exec>

In the above-mentioned application embodiments of the present invention, if the terminal device actively reports the DDF node value, the terminal device can report multiple DDF information or the storage location of the DDF information at one time; if the DM server obtains the DDF information by sending an operation command, it can also request Obtain multiple DDF information or storage locations of DDF information. In addition, the terminal device also needs to judge whether to feed back the corresponding MOI information according to each DDF information reported. If a DDF information does not contain the corresponding MOI information, it must also feed back the MOI information corresponding to the DDF information; If the DDF information includes corresponding MOI information, the MOI information corresponding to the DDF information may be fed back, or the MOI information may not be fed back.
