Description
Technical field
The present invention relates to Open Mobile Alliance (OMA, Open Mobile Alliance) equipment control (DM, Device Management) technical field, especially relate to a kind of maintaining method and terminal equipment thereof of device management tree.
Background technology
Open mobile alliance device management (OMA DM, Open Mobile Alliance DeviceManagement) standard is a kind of management, diagnosis and the technology of safeguarding mobile terminal device, it is by the aerial (OTA that downloads, Over The Air) mode manages terminal equipment, and wherein the bookkeeping to terminal equipment comprises: terminal equipment is carried out parameter setting, firmware update, software installation and upgrade and failure diagnosis etc.Wherein the mobile terminal device managed of OMA DM standard comprises mobile phone terminal, palmtop PC, notebook computer, embedded device and onboard system etc., does not get rid of any other mobile terminal device simultaneously.
As shown in Figure 1, for the holistic management framework model figure of existing DM standard, in this holistic management framework model figure, the equipment control agency (DM Agent) on the terminal equipment is used to explain and carry out the various administration orders that the DM server issues; The DM management tree of storing on the terminal equipment can be considered to a device management server (DMS, DM Server) interface that terminal equipment is managed by the DM agreement, comprise the basic management object (MO of a cover in this DM management tree, Management Object), DMServer reaches by the bookkeeping to each management object in the DM management tree terminal equipment resource is controlled.Wherein the administration order of each node of DM Server operation DM management tree comprises Get (obtaining order), Replace (replacing order), Exec (fill order), Copy (copy command) and Delete (delete command) etc.
As shown in Figure 2, configuration state schematic diagram for each management object in the management tree in the existing terminal equipment, the DM management tree of each terminal equipment must have root node, each child node on the tree is divided into internal node and leaf node, all belong to internal node as the connection parameter management object among Fig. 2, equipment information management object etc., and device id, manufacturer, terminal models all belong to leaf node.Each node in the management tree comprises permanent node (permanent nodes) and dynamic node (dynamic nodes), wherein permanent node is meant the node that device management server can not generate and delete at run duration, and for example device fabrication manufacturer built-in node in terminal equipment just belongs to permanent node; Dynamic node is meant the node that allows device management server dynamically to generate and delete at run duration.
OMA DM normalized definition the property value of a set of equipment management tree node, be used for each node is described, each property value mainly comprises: control of authority tabulation (ACL, Access Control List), multi purpose internet mail extensions (MIME, the Multipurpose InternetMail Extensions) type of type (Type), form (Format), title (Name), size (Size), title (Title), timestamp (TStamp), nodal value etc.Be that ACL by node realizes wherein, in ACL, identify the operating right of this device management server to this node is set by the configuration device management server to the control of authority of device management server operational administrative tree node; If certain during ACL describes order is not used the device management server sign, and has been to use " * " sign, think that then this command operation authority of this node is to open to pass through the authenticated device management server for all.For example following ACL expression formula:
Add＝ServerA&Delete＝ServerA&Replace＝ServerA+ServerB&Get＝*
Indication equipment management server A has Add, Delete and Replace authority to the node of this ACL sign, and device management server B has the Replace authority to the node that this ACL identifies, and any all have the Get authority by the authenticated device management server to the node that this ACL identifies.Wherein ACL can adaptive operational order comprise: Add, Delete, Exec, Get and Replace operational order.
If the ACL of certain node is empty in the device management tree, promptly the ACL expression formula of node is ACL=, thinks that then the operating right of this node can inherit the operating right of father node.
If certain operating right that comprises among the ACL of certain node only disposes a ServerID, when needs are cancelled this ServerID corresponding equipment management server and are carried out this operating right, will be with this ServerID deletion, for example the ACL expression formula of certain node is as follows:
Replace＝ServerA&Get＝ServerA+ServerB；
Then the ACL expression formula of this node will become behind the operating right of cancellation ServerA: Get=ServerB;
If cancellation all devices management server is to all operations authority of this node, then the ACL expression formula of this node will become: ACL=.
In order to make the entire equipment management tree controlled, can be that the root node of management tree distributes an initial ACL, and dispose this ACL and be: Add=*﹠amp; Get=* represents that promptly all pass through the authenticated device management server and can carry out the Add operation and Get operates to the root node of management tree.After all the authority deletions among the ACL of root node, all operations authority that the ACL of root node will be returned to initial setting up state or root node is set to " * ".
OMA DM regulation and stipulation can not be set the Replace authority to the root node of the device management tree in the terminal equipment at present, so just make device management server terminal equipment be managed in the process by the DM agreement, can occur when the ACL of node value changes and may cause some node to be managed, thereby become the rubbish node by any device management server.For example the ACL value configuring condition of each node is as shown in Figure 3 in equipment control subtree, if deletion ServerA is to the operating right of each node, the ACL value configuring condition of equipment control subtree then shown in Figure 3 can become situation as shown in Figure 4, after promptly deleting the operating right of ServerA to each node, the ACL value of NodeB can be inherited the ACL value of father node fully, and promptly the ACL value of NodeB becomes Add=*﹠amp; Get=* so just causes can carrying out operations such as Replace, Delete, Copy or Exec to node NodeB without any device management server, thereby makes it become rubbish subtree or rubbish node.
This shows, in the process that device management server manages terminal equipment by the DM agreement, if changing, the ACL value of node may cause occurring in the terminal equipment rubbish node or rubbish subtree, and too much rubbish node or rubbish subtree tend to waste a large amount of storage resources of terminal equipment and the system handles resource of wasting terminal equipment, thereby can reduce the disposed of in its entirety performance of terminal equipment; Simultaneously because device management server is by the whole management tree structure in the terminal equipment being got access to behind the device management server and discerning, come terminal equipment is carried out follow-up management with this, if have a large amount of rubbish nodes or rubbish subtree like this in the device management tree of terminal equipment, the data volume of obtaining in the time of will certainly making device management server obtain the management tree structure of terminal equipment strengthens, thereby having wasted transmission resource of network, is very valuable for the wireless network wireless transmission resources especially.

In OMA DM standard, each is to realize terminal equipment is managed by each node of device management tree of storing in the operation terminal device by the authenticated device management server, in order to control the corresponding management authority of distinct device management server to terminal equipment DM tree, terminal equipment is safeguarded corresponding ACL value respectively in each node of equipment of itself management tree, by device management server sign and corresponding administration authority relational expression are set for the ACL value of node maintenance, this node had corresponding administration authority with sign corresponding apparatus management server.
First kind of technical scheme of the present invention is when upgrading the ACL of respective nodes in the DM tree, may cause renewal owing to interdependent node ACL to cause and occur rubbish node or rubbish subtree in the terminal equipment, thereby can reduce the disposed of in its entirety performance of terminal equipment and the problem of waste transfer resource, and when proposing the ACL of respective nodes in upgrading terminal equipment DM tree, can prevent from terminal equipment, to occur the processing scheme of rubbish node or rubbish subtree preferably.
Be explained in detail to the main realization principle of technical solution of the present invention, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
As shown in Figure 5, the main realization principle flow chart of the maintaining method of the first kind of device management tree that proposes for the present invention, its main implementation procedure is as follows:
Step S10, terminal equipment upgrades processing to the ACL information of respective nodes in the DM tree;
A kind of more excellent mode be terminal equipment can receive send the update instruction of ACL information that (as being issued by the user) be used for triggering terminal renewal of the equipment respective nodes under the external world after, according to the update instruction that receives the ACL information of the respective nodes in the DM tree is upgraded processing;
Another kind of more excellent mode is that terminal equipment is in the administration authority process of certain DM Server of deletion, if when in the DM tree, traversing the node that comprises this DM Server ID that will delete in the ACL information, this DM Server ID that comprises in the ACL information with the node that traverses deletes, thereby has also reached the purpose that the ACL information to this node upgrades.
Do not exist when safeguarding authority respectively in the ACL information of each node between step S20, terminal equipment this node, root node and this node and the root node after judging renewal, this node is safeguarded processing.
Wherein to satisfy above-mentioned Rule of judgment carried out mode that node that ACL upgrades safeguards can but be not limited to refer to following processing mode:
Terminal equipment judge this more new node whether be dynamic node, if in DM tree, be the subtree deletion of root then, or under the situation that the user confirms, be the subtree deletion of root with this node with this node;
2. the authority of safeguarding of this node is opened to all DM Server by authentication;
3. the DM Server of specified takes over the authority of safeguarding of this node.
Safeguard that wherein authority can refer to that specifically DM Server carries out the replacement authority (Replace authority) of upgrading processing to DM tree node in the terminal equipment; Can refer to that also DM Server carries out the erase right (Delete authority) that deletion is handled to DM tree node in the terminal equipment; Can also refer to Replace authority and Delete authority.
Be that example is carried out more detailed elaboration to the main realization principle of said method of the present invention to delete certain DM Server to the administration authority of terminal equipment below.As shown in Figure 6, be foundation first method principle of the present invention, at the main realization flow figure that certain DM Server of deletion safeguards DM tree under to the administration authority situation of terminal equipment, its specific implementation process is as follows:
S50, terminal equipment is in the administration authority process of sweep equipment management server, according to the sign (ID) of the device management server that will delete traversal DM tree, promptly the ACL value that whole DM is set each node scans, to search the node that comprises this DM Server ID among the ACL respectively;
A kind of more excellent execution mode is the delete instruction that terminal equipment receives the sweep equipment management server administration authority that the user issues, and carries out the processing of the administration authority of this device management server of deletion according to the DM Server ID that will delete that comprises in this delete instruction.
Another kind of more excellent execution mode is the delete instruction that terminal equipment receives the sweep equipment management server administration authority that the corresponding device management server issues, and carries out the processing of the administration authority of this device management server of deletion according to the DM Server ID that the correspondence that comprises in this delete instruction will be deleted.
Step S60, terminal equipment are when searching each node that satisfies above-mentioned condition, and this DM Server ID that comprises among the ACL with this node deletes; And
Step S70, the ACL that judges each node between node, root node and this node and the root node of deleting this DM Server ID does not exist respectively when safeguarding authority (as Replace authority and/or Delete authority) behind this DM Server ID of deletion, and this node is safeguarded processing.
Wherein can be in advance in terminal equipment maintenance strategy of storage, terminal equipment just can be safeguarded this node according to this maintenance strategy of storing in advance and handle judging when satisfying the node that above-mentioned condition needs to be serviced; Can certainly be when needs be safeguarded this node, the prompting user imports corresponding maintenance strategy, and terminal equipment just can be carried out corresponding the maintenance to this node according to the maintenance strategy of user's input and handle.
Wherein can but the node that is not limited to adopt one of following three kinds of maintenance strategies to need to be serviced satisfying condition is safeguarded processing, its maintenance strategy can be preestablished by the user, also can self be preestablished by terminal equipment (DM Client), can also be preestablished by the device management server that is about to deleted administration authority:
(1) will be that the whole subtree of root is deleted processing with the dynamic node that satisfies condition among the above-mentioned steps S70 that searches, terminal equipment is carried out the node that satisfies condition among the step S70 that searches in above-mentioned steps S70 like this: terminal equipment judges whether this node is dynamic node, is the whole subtree of root if then delete with this node in the DM tree; Perhaps
Whether terminal equipment judges whether this node is dynamic node, be the whole subtree of root if then point out the user to confirm to delete with this node, and after the affirmation instruction that receives the user, deletion is the whole subtree of root with this node in the DM tree.
The authority (as Replace authority and/or Delete authority) of safeguarding of the node that satisfies condition among the above-mentioned steps S70 that (2) will search is opened by the authenticated device management server to all, terminal equipment is carried out the node that satisfies condition among the step S70 that searches in above-mentioned steps S70 like this: in for the ACL of this node maintenance, safeguard that the corresponding DMServer ID of authority (as Replace authority and/or Delete authority) is set to *.
(3) safeguard authority (as Replace authority and/or Delete authority) by what the device management server of regulation was taken over the node that satisfies condition among the above-mentioned steps S70 search, terminal equipment is carried out the node that satisfies condition among the step S70 that searches in above-mentioned steps S70 like this: in for the ACL of this node maintenance, safeguard that the corresponding DM Server ID of authority (as Replace authority and/or Delete authority) is set to the DM Server ID of this regulation.The wherein concrete Replace authority and/or the Delete authority of which device management server to take over the node that satisfies condition that searches of specifying by, can preestablish by the user, also can self preestablish, can also preestablish by the device management server that is about to deleted administration authority by DM Client.
The foregoing description principle is when terminal equipment is cancelled certain device management server to its administration authority, whole DM tree is carried out traversal processing (can adopt degree of depth traversal mode or adopt range traversal mode), promptly the ACL information to each node in the whole DM tree scans, if find to comprise among the ACL of certain node the sign of this device management server, then with this device management server sign deletion among the ACL of this node; And to judging after this device management server sign of this knot removal, if also have in the ACL information of each node between this node, root node and this node and the root node when safeguarding authority (as Replace authority and/or Delete authority), then the processing procedure of safeguarding to this node finishes, and normally carries out the scanning of other node; If do not exist in the ACL information of each node between this node, root node and this node and the root node when safeguarding authority (as Replace authority and/or Delete authority), then terminal equipment selects wherein a kind of processing mode that this node is carried out follow-up maintenance processing in following 3 kinds of maintenance strategies, wherein this maintenance strategy can be the strategy that the user sets, also can be the default treatment strategy of DM Client, can also be the strategy that is about to the device management server setting of deleted administration authority:
1. terminal equipment judges whether this node is dynamic node, if then in DM tree deletion be the whole subtree of root with this node, or the request user confirm after again in the DM tree deletion be the whole subtree of root with this node;
2. the Replace authority and/or the Delete authority of this node being opened by the authenticated device management server to all, promptly on the basis of the existing right assignment of node ACL that this device management server of deletion identifies, increase: its Replace authority and/or Delete authority corresponding equipment management server sign are made as " * " for being provided with among the ACL of this node maintenance;
3. set the Replace authority and/or the Delete authority of taking over this node by the device management server of certain regulation, promptly on the basis of the existing right assignment of node ACL after this device management server sign of deletion, increase: its Replace authority and/or Delete authority corresponding equipment management server are identified the sign that changes to this adapter device management server.Wherein have by which device management server and take over and to be set by the user, also can set, can also set by the device management server that is about to deleted administration authority by DM Client.
To enumerate a specific embodiment below more specifically sets forth the main realization principle of said method of the present invention:
Suppose certain by having added a subtree on the device management server of the authorizing DM tree in certain terminal equipment, the subtree of this interpolation and authority thereof as shown in Figure 7, wherein in the DM of terminal equipment tree, the authority of NodeB is:
Get＝*&Add＝*&Replace＝ServerA&Delete＝ServerA
The ACL of node NodeC and NodeD inherits the ACL information of NodeB node.
That is: ServerA has Replace authority and Delete authority to these three nodes respectively; The Get authority of these three nodes and Add authority then can be opened by the authenticated device management server to all respectively.
As sweep equipment management server A during to the administration authority of this terminal equipment, terminal equipment just will carry out traverse scanning to the DM tree of self, in the ACL information of each node of DM tree, to delete the ServerA sign respectively, set among the ACL of each node after the deletion ServerA sign at DM, this subtree and authority situation thereof are just as shown in Figure 8 in the terminal equipment, then node NodeB is and the direct-connected node of root node Root as can be seen, and the ACL of this node no longer exists Replace authority and Delete authority after deletion ServerA sign, and do not have Replace authority and Delete authority in the ACL information of root node too, so terminal equipment just can be given to safeguard in the following manner to this NodeB:
A kind of mode is that deletion or request user confirm that the back deletion is the whole subtree of root with this node NodeB, and the subtree view after the deletion as shown in Figure 9;
Another kind of mode is that the Replace authority of this node NodeB can be opened by the authenticated device management server to all, and the subtree view after it is handled as shown in figure 10;
Another kind of mode is the Replace authority that is continued to take over this node NodeB by certain specific device management server (as ServerB), and the subtree view after it is handled as shown in figure 11.
With deletion DM Server first kind of DM tree of the administration authority of terminal equipment safeguarded performance with respect to the present invention is above-mentioned, terminal equipment can also be in the administration authority process of certain device management server of deletion to self, the ACL information of each node in the DM tree of traverse scanning self storage, and the sign deletion of this device management server that comprises among the ACL with each node in the whole DM tree, follow-up (execution immediately after can in the ACL of each node in the DM tree, deleting this server identification that finishes, also can cross stipulated time Duan Houzai to carry out) judge the node of each deletion server identification respectively, whether also exist among the ACL of each node between root node and this node and the root node and safeguard authority (as Replace authority and Delete authority), safeguard processing for the node of not safeguarding authority (, also not having the Delete authority) as both there not being the Replace authority.
According to above-mentioned thought, please refer to Figure 12, this figure is according to first method principle of the present invention, at the second embodiment process chart that certain DM Server of deletion safeguards DM tree under to the administration authority situation of terminal equipment, its main implementation procedure is as follows:
