Embodiment
The solution main thought of the embodiment of the present invention is: server issues a Replace order after expansion, and client is resolved this Replace order, if judge the Target element of this Replace order, uses TNDS attribute to replace; Carry out the Replace operation based on TNDS attribute; After operating successfully, replace the value of the upper all interdependent node respective attributes of whole stalk tree or Value, otherwise maintain former state, thereby simplify existing loaded down with trivial details operating process, make the intercommunication operation of server and client more efficient, Engineering Project Implementation is simplified.
As shown in Figure 2, a kind of terminal equipment firmware optimization method based on TNDS that one embodiment of the invention proposes, comprising:
Step S101, the Replace order of Replace operation is carried out in the requirement that client server issues to the subtree of designated root node;
The present embodiment can be realized by air interface telemanagement, upgrade terminal equipment firmware, specifically by server, issues a Replace order after expansion to client, by client, carries out corresponding Replace operation.
Particularly, the present embodiment is considered: the usage of Replace generally can be used for revising nodal community and Value value.Example of Replace order below:
In addition, consider that OMA-TS-DM_TNDS-V1.2 can be so that be converted into possibility between a whole or part for MO or management tree and an xml or wbxml document mutually, thus the troublesome operation of avoiding multinode to order more.As the TNDS object of byte stream, there is its oneself mime type form.Therefore,, if equipment or server are supported this mime type, can utilize same DM order to operate whole subtree.
The present embodiment is single for existing Replace operation, can not to it, expand by a subcommand direct control one stalk tree this point, has added the operation of TNDS attribute in Replace operation, makes it possess the ability of direct control one stalk tree.
The example that wherein operates effective attribute list is as follows:
" list=TNDS+Value+ACL "--only access Data and ACL;
All other of " list=TNDS-Format "--access except Format supported attribute;
Utilize the Replace operation after above-mentioned expansion to carry out server and client intercommunication between the two operation.
Particularly, first, server issues Replace order to client by DM order, requires the subtree of designated root node to carry out Replace operation.Its message is as follows:
With the example that is operating as to Name attribute, server issues Replace ./antivirus_data/version list=TNDS+Name antivirus-inc/20020213a/1 order by DM order, and this operation will be carried out the operation of Replace Name to take the subtree that path ./antivirus_data/version is root node.
Step S102, resolves described Replace order, judges whether the Target element of described Replace order uses TNDS attribute to replace; If so, enter step S103; Otherwise, enter step S107;
Step S103, carries out the Replace operation based on TNDS attribute;
Step S104, whether decision operation is successful, if so, enters step S105; Otherwise, enter step S106;
Step S105, structure DM protocol massages feeds back to described server, and described DM protocol massages carries the successful corresponding state code of operation.
Step S106, returns operation failure corresponding state code to described server, terminated task, and Replace is before operated to successful node make rollback reduction.
Step S107, the Replace command process flow process of giving tacit consent to, and return to step S104.
In above-mentioned steps S102-step S107, when client, receiving after the Replace order that server issues, this Replace order is resolved, is to have used TNDS attribute to replace if be resolved to the Target element of this order; The processing of client will utilize the associative operation of TNDS to replace and specify the value value of all interdependent nodes under subtree or the property value of appointment by the value of the Data element assignment in order composition so.
If in this Replace operation, one of them node R eplace operation failure of whole subtree, think whole operation failure, must exit operation (also just can not carry out Replace operation to the node not operating afterwards again), and must carry out rollback to the successful operation of Replace before, it is reduced into not preoperative value; Client can be returned to an effective status code to server for this Replace order.
After client Replace EO, if Replace operates successfully, replace the upper respective attributes of all nodes of whole stalk tree or the value of Value, otherwise maintain former state.But operate successfully or failed client all can be returned to an effective conditional code to server for this order, and with the form announcement server of DM session message.
Particularly, with the above-mentioned example that is operating as to Name attribute, server issues Replace ./antivirus_data/version list=TNDS+Name antivirus-inc/20020213a/1 order by DM order, and this operation will be carried out the operation of Replace Name to take the subtree that path ./antivirus_data/version is root node.
Client is received after this Replace order, transfer to the DM protocol stack of client to process, first protocol stack judges this operation is to belong to the Replace operation that operates whole subtree, and then judges Replace operation or the operation of running node Value that this operation is running node attribute (being Name attribute in this example).
All nodes under the DM protocol stack traversal subtree of client, once be leaf node, it is carried out to Replace Name operation, first judge the ACL property of this node, if ACL property meets the demands, carry out Replace operation, otherwise return operation failure corresponding state code, terminated task, and Replace is before operated to successful node make rollback reduction.
After ACL property inspection is passed through, if the operation of Replace nodal community also should check after this attribute of modification, whether result can cause management tree inconsistent., shown in this example, because be the operation for Name attribute, be the equal of for example that node is carried out to rename, so check as follows step:
Replica node name before command execution; The final stage of getting URI is made and is changed, and needs search on the brother of node of present node, whether have the node of same name.
After aforesaid operations is finished, corresponding state to be piled up in Status element, structure DM protocol massages replies to this Replace command operation result of server.
Thus, by such scheme, realize server and client with the intercommunication operation of Replace order, before supposing to carry out, under subtree, certain property value is V1, after carrying out, under subtree, all nodes are modified to V2 according to needs unification, finally complete the Replace operation of a subtree.
Compared with prior art, existing Replace operation can only operate for properties or the value of individual node, each Replace operation is if operation Multi-instance must be with a plurality of Item elements, such command forms is loaded down with trivial details, be difficult for understanding, and cannot operate subtree, when operating, multinode can bring certain burden to server and client side, and one aspect of the present invention has been expanded the device intercommunicating operation in DM agreement, make the intercommunication operation of server and client more efficient, simple; Increase on the other hand so a kind of mode and carry out server and client intercommunication operation, can simplify the requirements use case of practical engineering project, be convenient to the project implementation.
As shown in Figure 3, one embodiment of the invention proposes a kind of terminal equipment firmware based on TNDS and optimizes client, comprising: receiver module 201, analysis judgment module 202, operational module 203 and result feedback module 204, wherein:
Receiver module 201, the Replace order of Replace operation is carried out in the requirement issuing for reception server to the subtree of designated root node;
Analysis judgment module 202, for resolving described Replace order, judges whether the Target element of described Replace order uses TNDS attribute to replace; If so,
Operational module 203, while using TNDS attribute to replace for judge the Target element of described Replace order when analysis judgment module, carries out the Replace operation based on TNDS attribute;
Result feedback module 204, after operating successfully as Replace, structure DM protocol massages feeds back to described server, and described DM protocol massages carries the successful corresponding state code of operation.
The present embodiment can be realized by air interface telemanagement, upgrade terminal equipment firmware, specifically by server, issues a Replace order after expansion to client, by client, carries out corresponding Replace operation.
Particularly, the present embodiment is considered: the usage of Replace generally can be used for revising nodal community and Value value.Example of Replace order below:
In addition, consider that OMA-TS-DM_TNDS-V1.2 can be so that be converted into possibility between a whole or part for MO or management tree and an xml or wbxml document mutually, thus the troublesome operation of avoiding multinode to order more.As the TNDS(Tree and Description Serialization of byte stream, tree and serializing is described) object has its oneself mime type form.Therefore,, if equipment or server are supported this mime type, can utilize same DM order to operate whole subtree.
The present embodiment is single for existing Replace operation, can not to it, expand by a subcommand direct control one stalk tree this point, has added the operation of TNDS attribute in Replace operation, makes it possess the ability of direct control one stalk tree.
The example that wherein operates effective attribute list is as follows:
" list=TNDS+Value+ACL "--only access Data and ACL;
All other of " list=TNDS-Format "--access except Format supported attribute;
Utilize the Replace operation after above-mentioned expansion to carry out server and client intercommunication between the two operation.
Particularly, first, server issues Replace order to client by DM order, requires the subtree of designated root node to carry out Replace operation.Its message is as follows:
With the example that is operating as to Name attribute, server issues Replace ./antivirus_data/version list=TNDS+Name antivirus-inc/20020213a/1 order by DM order, and this operation will be carried out the operation of Replace Name to take the subtree that path ./antivirus_data/version is root node.
When the receiver module 201 of client receives that after the Replace order that server issues, 202 pairs of these Replace orders of analysis judgment module are resolved, and are to have used TNDS attribute to replace if be resolved to the Target element of this order; The operational module 203 of client will utilize the associative operation of TNDS to replace and specify the value value of all interdependent nodes under subtree or the property value of appointment by the value of the Data element assignment in order composition so.
If in this Replace operation, one of them node R eplace operation failure of whole subtree, think whole operation failure, must exit operation (also just can not carry out Replace operation to the node not operating afterwards again), and must carry out rollback to the successful operation of Replace before, it is reduced into not preoperative value; Client can be returned to an effective status code to server for this Replace order.
After client Replace EO, if Replace operates successfully, replace the upper respective attributes of all nodes of whole stalk tree or the value of Value, otherwise maintain former state.But operate successfully or the result feedback module 204 of failed client all can be returned to an effective conditional code to server for this order, and with the form announcement server of DM session message.
Particularly, with the above-mentioned example that is operating as to Name attribute, server issues Replace ./antivirus_data/version list=TNDS+Name antivirus-inc/20020213a/1 order by DM order, and this operation will be carried out the operation of Replace Name to take the subtree that path ./antivirus_data/version is root node.
Client is received after this Replace order, transfer to the DM protocol stack of client to process, first protocol stack judges this operation is to belong to the Replace operation that operates whole subtree, and then judges Replace operation or the operation of running node Value that this operation is running node attribute (being Name attribute in this example).
All nodes under the DM protocol stack traversal subtree of client, once be leaf node, it is carried out to Replace Name operation, first judge the ACL property of this node, if ACL property meets the demands, carry out Replace operation, otherwise return operation failure corresponding state code, terminated task, and Replace is before operated to successful node make rollback reduction.
After ACL property inspection is passed through, if the operation of Replace nodal community also should check after this attribute of modification, whether result can cause management tree inconsistent., shown in this example, because be the operation for Name attribute, be the equal of for example that node is carried out to rename, so check as follows step:
Replica node name before command execution; The final stage of getting URI is made and is changed, and needs search on the brother of node of present node, whether have the node of same name.
After aforesaid operations is finished, corresponding state to be piled up in Status element, structure DM protocol massages replies to this Replace command operation result of server.
Thus, by such scheme, realize server and client with the intercommunication operation of Replace order, before supposing to carry out, under subtree, certain property value is V1, after carrying out, under subtree, all nodes are modified to V2 according to needs unification, finally complete the Replace operation of a subtree.
Compared with prior art, existing Replace operation can only operate for properties or the value of individual node, each Replace operation is if operation Multi-instance must be with a plurality of Item elements, such command forms is loaded down with trivial details, be difficult for understanding, and cannot operate subtree, when operating, multinode can bring certain burden to server and client side, and one aspect of the present invention has been expanded the device intercommunicating operation in DM agreement, make the intercommunication operation of server and client more efficient, simple; Increase on the other hand so a kind of mode and carry out server and client intercommunication operation, can simplify the requirements use case of practical engineering project, be convenient to the project implementation.
