In the embodiment of the present invention, since the terminal device saves the DDF information, the network side obtains the DDF information from the terminal device, so after the terminal device increases, deletes, or updates the DDF information due to functional upgrade or hardware addition, the DM server The changed DDF information can be acquired and the management efficiency of the terminal device can be improved.

[44] The specific implementation manner of the embodiment of the present invention may be:

[45] For the terminal side

[46] The saved DDF information or the storage location of the DDF information is transmitted, and the storage location of the DDF information or the DDF information is stored in the terminal device.

[47] The operation of saving the storage location of the DDF information or the DDF information in the terminal device may be completed by the manufacturer before the terminal device leaves the factory, or may be completed by the terminal device after the function upgrade or adding new hardware. The storage location of the DDF information may be a URI (Uniform Resource)

Identifier, Uniform Resource Identifier) or URL (Uniform Resource)

Locator, Uniform Resource Locator, etc. The path information is stored in the terminal or at a certain location in the network. For example, when the terminal performs the function upgrade, the DDF information corresponding to the function is generated in the terminal, and the storage location of the DDF information is saved in the terminal device (of course, the DDF corresponding to the generated function may also be generated. The information is directly stored in the terminal device, so that the DM server can directly obtain the information without obtaining the guidance of the corresponding path information. For example, when the terminal adds the hardware, the storage location of the DDF information corresponding to the hardware function is saved in the terminal. In the device, the DDF information corresponding to the hardware function is saved by the manufacturer of the hardware somewhere in the network.

[48] In the embodiment of the present invention, the storing location of the DDF information or the DDF information in the terminal device may be: storing the DDF information or the storage location of the DDF information in a management tree of the terminal device DM, And the storage location of each DDF information or DDF information is stored as a node value in a leaf node. The location of the DDF information or the storage location of the DDF information in the DM management tree may be implemented in multiple manners. One implementation manner may be: setting a dedicated DDF-related information in the DM terminal management tree. For nodes such as DDF information, storage location of DDF information, etc., the storage location of each DD F information or DDF information is stored in the node dedicated to storing DDF related information, respectively. Under the leaf node. The storage location of the DDF information or the DDF information may also be saved in a specified location in the DM management tree, and the designated location may be a location specified by a user, or a terminal manufacturer, or the like.

[49] In order to enable the DM server to quickly obtain the required DDF information, the MOI (Management Object Identification) information corresponding to the DDF information may be saved in the DDF information or the storage location of the DDF information. a location, for example, storing the MOI information corresponding to the DDF information as a node value in another leaf node under the location where the D DF information or the storage location of the DDF information is located (the leaf node storing the MOI information and The leaf nodes storing the DDF information corresponding to the MOI information or the storage location of the DDF information are in a parallel position in the management tree, and correspond to). The MOI information corresponding to the DDF information refers to the MOI information of the MO (e.g., function) corresponding to the DDF information. If the corresponding MOI information is not included in the DDF information, the corresponding MOI information must be configured at the location where the DDF information or the DDF information storage location is located. Otherwise, the corresponding MOI information may be optionally configured at the location.

[50] The location where the DDF information or the DDF information is stored is a node, and the location and structure of the node in the DM management tree may have multiple implementation manners. A specific structure of the node may be, if If the node only contains the storage location of the DDF information or the DDF information, the DDF information or the DDF information storage location is saved as the node value; if the node further includes the MO I information corresponding to the DDF information, The DDF leaf node and the MOI leaf node are further included in the node, and the storage location of the DDF information or the DD F information is saved as the DDF leaf node value, and the corresponding MOI information is saved as the MOI leaf node value. In order to implement the operation of the node storing the DDF related information by the DM server, in order to obtain the DDF information, the location of the node in the DM management tree needs to be notified to the DM server in advance, and the operation may be performed by the manufacturer of the terminal device, or may be performed by the terminal. Device execution.

The method for transmitting the saved DDF information or the DDF information in the foregoing embodiment of the present invention may be: the terminal device actively sends the DDF information or the storage location of the DDF information, where The storage location of the DDF information or the DDF information is one or more; 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. In this case, the terminal device may also send the MOI information corresponding to the DDF information, and the specific process is: the terminal device determines whether the sent DDF information already includes the MOI information, and if yes, may not send the MOI information. Otherwise, the MOI information must be sent. [52] wherein, if the terminal device actively sends the information, the information may be the storage location of all D DF information and DDF information saved in the terminal device, or may be added when the terminal device function is upgraded or new hardware is added, etc. Deleted or updated DDF information and DDF information storage location;

[53] 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 manner includes: if the operation command is to obtain all D DF information The command, the shell I" sends 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, the specified multiple DD F information or DDF information is sent Or the storage location of the DDF information corresponding to the specified MOI information, if the operation command is to obtain the corresponding DDF information or the storage location of the DDF information according to the MOI information in the command, if yes, Sending the DDF information or the storage location of the DDF information, otherwise, feeding back the error information; or, if the operation command is a command to acquire new DDF information, searching for the presence of new DDF information according to the command or The location where the DDF information is stored, if present, the new DDF information or DDF information is sent. The storage location, otherwise, the message without the new DDF information is added, and the new DDF information refers to the DDF information added, deleted or updated after the terminal device sends the message once.

[54] In the above process, if the terminal device actively sends information, one or more DDF information, or the storage location of the DDF information and the corresponding MOI information may be sent at one time. For example, sending all DDF related information in the terminal device to the DM server at a time, or sending a plurality of DDF related information added, deleted or updated to the DM server when the terminal device performs function upgrade, adding new hardware, and the like; If the terminal device feeds back the DDF related information according to the received operation command, the storage location of the one or more DDF information or the DDF information and the corresponding MOI information may be fed back according to the operation command. If the location of the DDF information or the DDF information is fed back, the terminal device needs to determine whether the corresponding MOI information is included in each DD F information, and the DDF information that does not include the corresponding MOI information needs to be fed back. Corresponding MOI information.

[55] For the network side

[56] receiving the information sent by the terminal device; then, acquiring the DDF information from the information sent by the terminal device, or acquiring the storage location of the DDF information, and acquiring the DDF information according to the storage location. The above operations can be specifically performed by the DM server. In the embodiment of the present invention, before the step of receiving the information sent by the terminal, the operation command may be sent to the terminal device, where the operation command may specifically include: acquiring a command of all DDF information; or acquiring the specified a command of a plurality of DDF information; or, a command to acquire DDF information corresponding to the MOI information; or a command to acquire new DDF information.

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

[59] Application Example 1

[60] This application embodiment will explain in detail how to implement DDF information or DDF information storage location in the terminal device.

[61] The operation of saving the DDF information or the DDF information storage location in the terminal device may be performed by the manufacturer, that is, the DDF information is preset by the manufacturer on the DM management tree of the terminal device before the terminal device leaves the factory, and Executed by the terminal device, that is, in the case of a function upgrade or adding new hardware or the like, the terminal device adds the DDF information thus generated, deleted or updated to its DM management tree.

[62] Saving the DDF information or the storage location of the DDF information on the DM management tree of the terminal device may be specifically completed by instantiating the X node under the DDFNode node reserved in the DM management tree for saving the information. In the X node shown in Figure 1, "X" indicates that the node has not been instantiated, and the "*" sign indicates that the node can appear 0 to many times, that is, there may be no such node, or there may be multiple of the parallel node. By storing the DDF information or the storage location of the DDF information after instantiating the X node, as shown in FIG. 2, the node names of each node are marked in the figure, respectively DDF0, DDF I s DDF2 and DDF3, and each The node value of each node is the storage location of DDF information or DDF information. For example, the value of node DDF0 is the DDF information of all basic functions in the factory management tree or the storage location of the DDF information. The values of nodes DDF1 and DDF2 are respectively DM

Account (DM Account) Management Object and SCOMO (Software Component Management

Object, software component management object) DDF information or the storage location of the DDF information, the value of the node DDF 3 is the DDF information of the Function function or the storage location of the DDF information. The format of the node value can be XML (Extensible Markup)

Language, Extensible Markup Language) format. The location where the DDF information is stored may be a URI Locator, Uniform Resource Locator, etc. The path information is stored in the terminal or at a certain location in the network. For example, when the terminal performs the function upgrade, the DDF information corresponding to the function is generated in the terminal, and the storage location of the DDF information is saved in the terminal device (of course, the DDF corresponding to the generated function may also be generated. The information is directly stored in the terminal device, so that the DM server can directly obtain the information without the corresponding path information. In another example, when the terminal adds the hardware, the storage location of the DDF information corresponding to the hardware function is saved in the terminal device. The DDF information corresponding to the hardware function is saved by the manufacturer of the hardware somewhere in the network.

[63] The location of the node storing the storage location of the DDF information or the DDF information in the management tree may be implemented in various manners, for example, may be set in the DM management tree to store the DDF information or the D DF. The node where the information is stored and the node corresponding to the MOI information may be referred to as a DDFNode node. Taking the management tree structure shown in Figure 3 and Figure 4 as an example, the ./DevDetail/ Ext/ in Figure 4

The X node in the DDFNode path is instantiated to save the DDF information or the storage location of the DDF information. As shown in Figure 5, all DDF information or DDF information is stored under a node named DDFNode, node 0. The node value of ~3 is the storage location of different DDF information or DDF information. After adding new functions to the terminal device, nodes such as 4 and 5 can be added to store the generated DDF information or the storage location of DDF information. It should be noted that the path in the above example is not a limited path. In practice, it may be another path, 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:

[64] <MgmtTree>

[65] <VerDTD> 1.2</VerDTD>

[66] <Node>

[67] <NodeName>DevDetail</NodeName> <!--The node name is DevDetail ->

[77] <DFFomiat><node/></DFFormat>< !- DDFNode node format ->

[89] </Node>

[90] </Node>

[91]

[92] </Node>

[93]

[94] </Node>

[95] </MgmtTree>

[96] The above information describes the structure and properties of the DevDetail (device details) management object. The description gives the location of the DDFNode node through the hierarchy and gives its structure, ie the DDFNode node includes <NodeName/> Node, which indicates that there is an x node under the DDFNode node. The terminal can add the DDF information or DDF information storage location of the new function at this location, and its Occurrence (the number of occurrences) is ZeroOrMore (0 or more). After the DM server knows the above information, it can learn the location and its attributes of the DDFN ode node stored in the terminal device, and then manage the node. [97] In order to enable the DM server to quickly obtain the required DDF information, the application embodiment may also set the correspondence between the MOI and the DDF in the DM management tree. As shown in FIG. 5, the storage location of the DDF information or the DDF information corresponding to the MO 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 (below Same). After instantiating the X node, as shown in Figure 6, the DDFNode node contains several child nodes (each child node represents a terminal management tree or a function).

(such as MO) and so on) (nodes 0~3), each subnode representing MO contains a DDF node and an MOI node, and the DDF node value is the storage location of the DDF information or DDF information corresponding to the MO. The MOI node value is the MOI information of the MO. In this way, the terminal or the DM server can find the corresponding DDF information or the storage location of the DDF information according to the MOI information.

[98] Application Example 2

[99] This application example describes the process of obtaining DDF information by the DM server by taking the DDF information configuration of the terminal device as an example.

[100] As shown in FIG. 7, it is assumed that the DDF information of some functions has been preset in the management tree after the terminal device leaves the factory, specifically including the DDF information of the DM management tree and the DDF information of the SCOMO, wherein the DDF information of the terminal management tree is saved. On node 0 under the DDFNode node; the DDF information of SCOMO is stored on the child DDF node of node 1, and its MOI information is stored on another child node MOI node. The server knows in advance the location of the DDFNode node in the management tree. The process of specifically obtaining DDF information may include:

[101] Step 21: The DM server sends a command to obtain all DDFs.

[102] Step 22: After receiving the command, the terminal device feeds back the node value of the node 0 and the DDF node value under the node 1 to the DM server, where the node value of the node 0 is the DDF information of the DM management tree. The DDF node value under the node 1 is the DDF information of the SCOMO;

[103] Step 23: After receiving the node value, the server analyzes the node value, and learns the structure and attributes of the terminal device DM management tree and the SCOMO management object.

In the embodiment of the present application, if the DDI information does not include the MOI information, the DM server needs to obtain the MOI information corresponding to the DDF information, and specifically obtain the MOI node value by using the sent obtaining command (for example, In this example, the MOI node value under the node 1), in addition, if the DDF information includes the corresponding MOI information, the DM server may also extract the MOI information from the obtained DDF information, in this example, the DM server may obtain the obtained 1 The MOI information is extracted from the DDF node value under the node, for example, um is extracted: Oma:mo:oma-scomo:1.0, you know that this MO is version 1.0 of the software component management object. After obtaining the required DDF information, the DM server can manage the terminal device accordingly.

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

[106] Application Example 3

[107] In the embodiment of the present application, the case where the DM server acquires the DDF information corresponding to the MOI information from the terminal device by giving the MOI information will be described in detail.

[108] It is assumed that the terminal device performs the function upgrade based on the situation described in the second embodiment of the application, and adds a new function to the LAWMO, and then the DDF information corresponding to the LAWMO is generated on the terminal device, or is provided by the terminal device. The operator of the LAWMO function 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 storage location of the DDF information or the DDF information under the DDFNode node under the DM management tree. The structure of the DDFNode is as shown in FIG. 8. The node 2 is the LAWMO node, the node 2 includes a DDF node and an MOI node, and the DDF node value is DDF information corresponding to the LAWMO, and the MOI node value is M 01 information for LAWMO.

[109] The newly added DDF information may be sent to the DM server by the terminal device, or may be obtained by the DM server through an operation command.

[110] Wherein, if the DDF information is actively sent by the terminal device, the specific execution process may be: the terminal device initiates a session request message to the DM server; and when the session link is successfully established with the DM server, the method is sent to the DM server. a DDF node value, if the DDF information does not include corresponding MOI information, the shell I" also needs to send the MOI node value; the DM server receives the information, and obtains the DDF information from the information or the The storage location of the DDF information, if the DM server obtains the storage location of the DDF information, the DDF information is obtained according to the storage location. The information sent by the terminal device can be, but is not limited to, the following code segment:

[111] <Add>

[112] <CmdID>3</CmdID> [113] <Item>

[114] <SourcexLocURI>./ ······ /DDFNode/2/DDF </LocURIx/Source>

[115] <!-The above is the path to the LAWMO DDF value ->

[116] ―

[117] <Data><!-This is the DDF value of LAWMO -></Data>

[118] </Item>

[119] <Item>

[120] <SourcexLocURI>./ ······ /DDFNode/2/MOI </LocURIx/Source>

[121] <! Above is the storage path of LAWMO MOI ->

[122] ......

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

[124] <!- Above is the MOMO value of LAWMO ->

[125] </Item>

[126] </Add>

[127] The DDF node value and the MOI node value are included in the above code segment. If the MOI information is already included in the DDF information, the MOI node value may not be included in the code segment.

[128] Of course, the terminal device can also send multiple new DDF node values. In addition, in addition to the new DDF node value, the terminal device can also send updated and deleted DDF node values, and optionally send its corresponding MOI node value.

[129] If the DM server sends an operation command to the terminal device, the terminal device sends a DDF node value to the DM server according to the operation command, and may send different operation commands to the terminal device, thereby passing different operations. To obtain the required DDF information, the specific execution process can be:

[130] Method 1

[131] The operation command is an operation command for acquiring DDF information corresponding to the MOI information, and the terminal device searches for a corresponding MOI node in the DM management tree according to the MOI information in the operation command; and then corresponds the MOI node. The DDF node value is sent to the DM server; if the terminal device does not find the DDF node value, the error information is fed back to the DM server, indicating that there is no DDF information corresponding to the MOI information.

[132] If the DDF information is acquired by the first method, the terminal device DM manages the DDFNode node in the tree. The structure is as shown in FIG. 9 , wherein the Operations node includes a GetDDF node and an MOI node, and the GetDDF node is an executable node, and the DM server operates the node by command to obtain the required D DF information. The DM server can operate the DDFNode node using an Exec command, a Replace command, or an Alert command or the like.

[133] Where, if the DM server uses the Exec command to operate this node, its operational commands can be, but are not limited to, the following code snippet:

[134] <Exec>

[135] <CmdID>3</CmdID>

[136] <Item>

[137] <Target>

[138] <LocURI>./ · · ···· /DDFNode/Operations/GetDDF</LocURI>

[139] <!- Above is the path to the GetDDF operation that needs to be executed -->

[140] </Target>

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

[142] <!- Above is the MOMO of the LAWMO that needs to get its DDF value ->

[143] </Item>

[144] </Exec>

[145] The command contains MOI urn:oma:mo:oma-lawmo:1.0, which is the input data for the GetDDF operation.

[146] If the DM server uses the Replace command, the Replace command sends the MOI information to the MOI node under the Operati ons node, and then uses the Exec command to operate the GetDDF node to obtain the required DDF information.

[147] If the DM server uses the Alert command, the Alert command includes the MOI information, and the identifier of the DDF is required to be executed.
