Description

The method of equipment control and terminal, device, system

Technical field

The present invention relates to the method for equipment control and terminal, device, system, belong to network communications technology field.

Background technology

Mobile terminal is important component part in whole mobile operation service system.Equipment control (Device Management, be called for short DM) refer to by aerial download (Over The Air, being called for short OTA) mode downloads to packet terminal equipment from network side, and indicating terminal equipment processes, complete the functions such as subsequent parameter configuration, software installation, error diagnosis.

Open Mobile Alliance (Open Mobile Alliance DM, be called for short OMA DM) in the equipment control specification of design, realize the agreement support that terminal equipment is managed, as shown in Figure 1, for the overall structure schematic diagram that DM server manages terminal equipment, the DM client (Client) on terminal equipment is for the administration order of explaining and actuating equipment server (DM Server) issues.DM management tree on terminal equipment can be considered to the interface that device management server manages terminal equipment by DM agreement.On management tree, have one group of management object (Management Object is called for short MO), device management server is by reaching the object of office terminal resource to the operation of management object interior nodes (management node).

As shown in Figure 1, in prior art, the management of DM is carried out in two steps: boot configuration (Bootstrap) and follow-up management.Bootstrap occurs in server and terminal equipment and sets up before managing conversation carries out actual management, and Bootstrap is used for configuring account information (user name, password etc.) and configures some other parameters (as connected parameter).In follow-up management process, can set up managing conversation, server can obtain some essential informations (as: firmware version, software version, large object support etc.) of terminal as the foundation of follow-up management action by the management object of terminal equipment.

Although prior art has realized the agreement support that terminal equipment is managed, but still there is the problems such as managerial effectiveness, efficiency and communication flows, for example: server cannot know that the DM ability that terminal unit management object address, terminal support (as the support to software component management, tenability to firmware upgrade etc.) and terminal are used smart card to carry out again Bootstrap etc., are specifically summarized as follows fast:

1, carry out again (as after changing planes) after Bootstrap in terminal this locality, server cannot know that terminal carried out Bootstrap, may make the authentication-related information after authentication-related information and terminal Bootstrap that server preserves inconsistent, and then cause both sides to complete authentication and cannot manage normally;

2, in order to make server can know restriction or terminal the realize situation to management tree of terminal equipment to management tree, in prior art, manufacturer terminal is described its equipment and is issued the reference for equipment control side by DDF, but existing protocol server side cannot find its corresponding DDF by terminal equipment, the difficulty that makes server obtain DDF strengthens;

3, server cannot be known the MO type that terminal is supported, and waste Internet resources.Due to device description framework (Device Description Framework, be called for short DDF) be generally static, or seldom dynamically change, server is difficult to all MO types of knowing that terminal is supported according to DDF, server is only issuing after corresponding management order, by terminal return results to judge whether terminal supports certain DM ability, and a large amount of data (as software component management) are carried in the administration order meeting issuing, and have wasted server and Internet resources;

4, in prior art, server cannot obtain in batches terminal management in the mode of non-serializing and set a certain particular attribute-value that goes up all management nodes under some management subtrees, needs repeatedly getattr, and efficiency is low;

5,, server is large to the management node positioning difficulty of terminal, consumes air resource.Server is in order to obtain terminal management node, may need with terminal repeatedly alternately or obtain the whole bibliographic structure of terminal, takies thus air resource, increased the pressure of server;

6, in prior art, server cannot be carried out the multiple elements in single administration order by indicating terminal in order, make like this administration order that needs the orderly action of carrying out must be divided into multiple orders execution realize, increased like this cost that administrative messag and terminal parses are carried out;

7, in the time that terminal or action of server process take a long time, may cause conversation and then cause management activities to complete, make this management taking a long time become difficulty, in addition in the time that a side confirms to need to send administration order soon, cannot maintain current sessions, may interrupt current sessions, and after re-establish managing conversation while needing to send administration order, make cost become large;

8,, in the time that terminal has multiple MO example, server cannot know that current which example what come into force be, the difficulty of management server is strengthened.

Embodiment

Management based on DM mainly divides two stages to carry out: boot configuration (Bootstrap) and follow-up management.Bootstrap occurs in before server and terminal equipment set up managing conversation, it mainly completes account information at terminal configuration server (comprising address, user name, password of server etc.) and configures some other parameters (network insertion dot information etc.), and the information that the Bootstrap stage configures is the follow-up basis of setting up managing conversation.After completing the configuration of account information of server, server can manage terminal, and management activities completes in the managing conversation of server and terminal equipment foundation.

Be described in detail from boot configuration and follow-up management session two parts improvement of the present invention part below:

One, boot configuration

Bootstrap main purpose is the account information of configuration server, so that terminal can be set up normal managing conversation with server, can also configure some other relevant parameter information simultaneously, as connected parameter etc.Concrete configuration method is: the account information of the server that configure and out of Memory are used to client configuration (Client Provisioning, CP) file format or management object (Management Object, MO) serializing form encapsulation, then by the prepackage of dispatching from the factory, aerial push (OTA Push), or the mode such as smart card (SmartCard) is issued to terminal, terminal receives the boot configuration information of server, this boot configuration packets of information is containing the server identification of described server, terminal is used this boot configuration information guide configuration or reboot configuration.The groundwork of configuration is to convert thereof into server account management object (being referred to as below DMAcc) and other related management object, and terminal initiatively connects the corresponding server of this DMAcc with the controlled state on activation server afterwards.While connecting, server is known its user name by " LocName " (value of " AAUTHNAME " node of the name under DMAcc management object), and and then use password corresponding to this user name to authenticate, if eap-message digest (Message-Digest Algorithm 5, be called for short MD5) certification, also need to know random number (nonce), for preventing Replay Attack.

In various configuration modes, SmartCard mode is one configuration mode safely and easily, and it can carry out initial configuration easily, and reconfigures after the account information of terminal goes wrong or changes terminal (as mobile phone).Prior art has following problem when devices to be configured is reconfigured: if server has revised by OTA mode the password of preserving in terminal after initial configuration, but the encrypted message in the Bootstrap data on SmartCard is also unmodified, after reshuffle terminal this locality, can be to the password on DMAcc reset (returning to the value before amendment), it is reshuffled is local action, server cannot be known, make the password of terminal preservation and the password of server preservation inconsistent, cause server cannot set up normal managing conversation by the certification to terminal.

The embodiment of the present invention one has solved the allocation problem of above-mentioned boot configuration, mainly contains two kinds of methods and is described below:

1, as shown in Figure 2, terminal is in the boot configuration of server account information or reboot after configuration, sends conversation request message to server, and this conversation request message has been carried out Bootstrap or Bootstrap again for announcement server terminal;

Server is received after described conversation request message, the Bootstrap information of preserving from server, obtain the corresponding password of LocName, the nonce etc. that described conversation request message carries terminal is authenticated, certification is carried out initialization or replacement by rear to the authentication information of server side.

Terminal announcement server terminal has carried out Bootstrap or the method for Bootstrap is specific as follows again:

Terminal initiatively sends conversation request message to server in boot configuration or after rebooting configuration (re-Bootstrap), has carried out Bootstrap or re-Bootstrap with notification server terminal.In this conversation request message, can comprise: terminal equipment information, LocName, terminal authentication information, Bootstrap or again Bootstrap announcement information.Wherein Bootstrap or Bootstrap announcement information concrete methods of realizing is as follows again:

Terminal is used " Alert " order of particular type code to realize described announcement information, this Alert order and type codes thereof are specifically as follows: end message reports Alert order (that is: Generic Alert, command type code is 1226) or terminal affair report Alert order (that is: Client Event Alert, command type code is 1224) or increase a kind of new conversation type and report in order to this announcement information, be specially:

Use Generic Alert or Client Event Alert need to first define an event type, as org.openmobilealliance.dm.bootstrap, below taking Generic Alert as example, use the method for Client Event Alert similar:

Increase a kind of method that new conversation type reports in order to this announcement information: increase the type codes of a new Alert order, carry the Alert order of the type code in order to indicate new session type, the type code can use 1202.Example is as follows:

Terminal is carried above-mentioned Bootstrap announcement information in the conversation request message of initiating to server, server knows that terminal carried out Bootstrap or Bootstrap again receiving after request message by the announcement information carrying in resolving this conversation request message, then obtain server side preserve Bootstrap information in password terminal request is authenticated, in follow-up management server more new terminal preserve password.

For safety (as prevent malicious server from intercepting and capturing Replay Attack after this conversation request message), server can also again be initiated authentication challenge (Challenge) to terminal after the conversation request message certification that terminal is sent is passed through, in this Challenge, carry the new nonce that server generates, terminal receive server send challenge message after use new nonce generate new authentication information and send to server, server authenticates again to this terminal.Can carry out other bookkeeping in certification by rear server, as update server password.

Above-mentioned Bootstrap again can be that terminal equipment triggers (as Mobile phone card is inserted to a new cell-phone) under certain condition automatically or user triggers by end-user interface (UI).

If the Bootstrap information 2. on SmartCard is that terminal is renewable, boot configuration method is specific as follows: password and nonce that the DM order of terminal reception server is more preserved in the DMAcc management object of the device management tree of new terminal, be updated successfully rear terminal and use SmartCard operational order automatically to upgrade password and nonce information corresponding in the Bootstap file on SmartCard.The current password that can keep password, nonce and server in Bootstrap file to preserve by above-mentioned processing is consistent, like this can be without notification server after using this SmartCard to carry out again Bootstrap.

Boot configuration (Bootstrap) mode has multiple, but in the information in the DMAcc management object of terminal management tree that current Bootstrap generates, this account is not which kind of Bootstrap mode to generate record by, this makes server cannot differentiate from the mode of Bootstrap the level of security of Bootstrap, and the Bootstrap method that also cannot use each terminal is added up simultaneously.The embodiment of the present invention two has been described the method addressing this problem, specific as follows: in order to make server know the source of terminal Bootstrap, the present embodiment increases the Bootstrap which kind of mode a management node (as " Bootstraptype " in Fig. 3) is undertaken by with storage terminal in the DMAcc of terminal equipment management tree management object, it is the type of boot configuration, specific embodiment can be as shown in Figure 3, BootstrapType value can be integer, as shown in Table 1:

Table one boot configuration types value and corresponding implication

Terminal is stored in Bootstrap mode on this management node after Bootstrap success.Server issues Get order to obtain the Bootstrap mode of this account in terminal to this management node in managing conversation, and terminal is returned to this management node value after authentication server authority.

The embodiment of the present invention three has been described a kind of Bootstrap information processing method, occurs the situation of multiple DMAcc in order to prevent terminal from carrying out repeatedly Bootstrap to same server identification account.The method of concrete Bootstrap can comprise the steps:

1, on the management tree of terminal, search and whether have DMAcc management object corresponding to this ServerID, be specially: the value that contrasts the ServerID in current wish configuration Bootstrap information and the ServerID node in existing DMAcc management object, if identical for there being corresponding account information, otherwise for there is no corresponding account information.Carry out step 2 if find the DMAcc management object that this ServerID is corresponding on the management tree of terminal, otherwise carry out step 3;

2, judge that Bootstrap or Re-Bootstrap that this Bootstrap operation is repetition (can judge in several ways, as can be by user's confirmation), if the Bootstrap repeating, abandon Bootstrap operation, if Re-Bootstrap, directly refreshes the data on management node under the upper corresponding DMAcc management object of terminal management tree;

3, the account information in Bootstrap information is converted to the DMAcc management object in terminal equipment management tree, and is its assigns access control authority.

Embodiment mono-has introduced the method for boot configuration configuration above, can effectively solve user in prior art and carry out again (as after changing planes) after Bootstrap, server cannot know that terminal carried out Bootstrap, the impact of user terminal information before being subject to, the follow-up problem that may cause cannot carrying out again normal management.Embodiment bis-effectively settlement server cannot be known the mode of terminal Bootstrap, thereby cannot differentiate from the mode of Bootstrap the level of security of Bootstrap.Embodiment tri-provides processing method when same server identification is carried out repeatedly to Bootstrap, can prevent from causing occurring in terminal equipment management tree because of Bootstrap conflict the situation of the DMAcc management object of the same server identification of multiple correspondences, prevent repetition Bootstrap and cause account management confusion.

Be described in detail from follow-up management session section improvement of the present invention part below:

Two, managing conversation

Terminal is successfully being carried out after Bootstrap initial configuration, and server and terminal can be set up managing conversation and manage interacting message.Session comprises session establishment phase and two stages of management phase.Wherein session establishment phase mainly completes the certification of both sides' identity, simultaneously the terminal equipment essential information of terminal to report in equipment essential information (DevInfo) management object.Management phase server issues attended operation realization by the management object on the management tree of terminal (MO) and issues management activities to terminal, the management node of terminal management tree has the operational capacity of access control right (Access Control List is called for short ACL) with Control Server to management node.

1, in order to make server can know restriction or terminal the realize situation to management tree of terminal equipment to management tree, DM has designed device description framework (Device Description Framework, DDF), manufacturer terminal is described its equipment by DDF and is issued this DDF for equipment control side's (as server) reference, but existing protocol server side cannot find its corresponding DDF by terminal equipment, the difficulty that makes server obtain DDF strengthens.

The method of obtaining device description framework that the embodiment of the present invention is described as shown in Figure 4, comprising:

The URL of memory device describing framework on the management tree of terminal;

Server obtains the device description framework of terminal by described URL.

For convenient service device side is obtained DDF, can on the management tree of terminal, store the URL of DDF, make server can obtain by this URL the DDF of this terminal, also can on the management tree of terminal, store this DDF data, make server directly to obtain its DDF information from terminal, specifically be not limited to a kind of embodiment of Fig. 4, be described as follows:

1. the implementation method of the URL of terminal storage DDF: increase a management node on the device management tree of terminal, and the URL of its DDF is stored in to this node, as: while dispatching from the factory, give this node assignment on equipment, in equipment use procedure, upgrade (having upgraded storage address of DDF etc. as equipment vendor) according to concrete condition, this node can leave under existing equipment essential information (DevInfo) management object, or under equipment details (DevDetail) management object.This nodal community can be as shown in Table 2:

Table two DDF management node attribute

The URL of terminal storage DDF, management server obtain and the flow process that uses DDF as shown in Figure 5, briefly introduce the step that uses DDF by URL below:

Step 1, device management server obtain to terminal the URL storing on " DDF_Addr " node in management process, concrete grammar is: if this node leaves DevInfo management object in, terminal can be in conversation request message this information of active reporting, server obtains from the terminal session request message receiving; If this node leaves DevDetail management object in, after terminal, in management process, use Get order can obtain its value to this node;

Step 2, terminal return to device management server the address that DDF deposits;

Step 3, device management server connect long-range DDF storage server corresponding to the DDF storage address that obtains obtain DDF;

Step 4, long-range DDF storage server return to DDF description document to device management server;

Step 5-7, device management server generate management activities and terminal are managed as the reference frame of follow-up management according to DDF, and returning to execution result by terminal.

Device management server is in order to reduce the cost of the follow-up DDF obtaining, can be at local cache these DDF data of obtaining.

2. the implementation method of terminal storage DDF itself: increase a management node on the device management tree of terminal, and the content of its DDF is stored in to this node, can in the time that dispatching from the factory, give equipment this node assignment, in equipment use procedure, upgraded by DM client according to concrete condition, this node can leave under DevDetail management object.This nodal community is as shown in Table 3:

Table three DDF management node attribute

In this kind of method, server issues the value of obtaining order and can obtain this node, the i.e. content of DDF, the subsequently reference frame using this DDF as follow-up management to this node in management process.

Above-mentioned two kinds of methods of obtaining device description framework, can solve protocol server in prior art and cannot find the problem of its corresponding device description framework.

2, server and terminal can be set up managing conversation, only mean that server can operate the device management tree of terminal, but some function need to depend on specific management object and the Client Agent program in terminal (being called for short DM application), as: SCOMO etc., the situation of the DM application that each terminal is supported is not identical, its difference may be in the time dispatching from the factory, to realize difference, is likely also specific client to be installed in follow-up use procedure increased ability support.Whether terminal supports it is the basis that this DM application function is realized to a certain DM application, and for this reason, terminal needs the support situation of its DM application of notification server.Cannot know the situation (being MO type) of DM that terminal is supported application, the problem that management server difficulty is strengthened for solving server in prior art, the present embodiment increases management node to record the support situation of terminal to DM application on the management tree of terminal, the DM application that terminal of each node storage is supported.

Referring to Fig. 6, the present embodiment is designed to comprise internal node and child node thereof by increased management node, be internal node as " SupportedApp " node is set, it can be a node in DevInfo or DevDetail management object, its child node is a leaf node for " x* ", can there is Multi-instance in it, the corresponding DM application of each example, terminal is safeguarded this node according to actual conditions own, for example: if terminal has increased the support of certain DM application, terminal increases a leaf node and deposits this DM application message under SupportedApp node.Because each MO has corresponding management object mark (being called for short MOID), if the MOID of firmware management object is " urn:oma:mo:oma-fumo:1.0 ", so deposit the MOID of supported MO in this node, that is: ... the value of/SupportedApp/<x> node is MOID.

For DM application, no matter on management tree, the MO example of this DM application has how many (0 or one or more), as long as terminal is supported this DM application power, has and only have the MOID node of this MO under SupportedApp node.In management process, obtain terminal and support that the step of DM applicable cases is as follows:

A, server are determined need to obtain terminal D M application support situation;

B, server obtain (GET) to the SupportedApp node transmission of the device management tree of terminal orders the value of obtaining its child node and child node, and terminal is returned to accordingly result;

The nodal value (MOID) that C, server analysis are known, to determine the situation of DM that terminal is supported application.

The method of the present embodiment can settlement server cannot be known the situation of DM that terminal is supported application, and issues bookkeeping targetedly, make that the management of server can become more flexibly and effectively.

3, in management process, server needs the MO of locating terminal, and then the node under MO is operated to realize certain management function, in prior art, the positioning difficulty of the management node of server to terminal is large, consume air resource, server stress large, the present invention, in order to improve the location efficiency of server to the MO on the device management tree of terminal, provides management object root node location lookup method, as shown in Figure 7, comprising:

Server sends and obtains order to terminal, carries object run routing information described in obtaining order, carries the value filtering information that need to obtain simultaneously;

Terminal receives obtaining after instruction of server, obtains the appointment structural information of subtree and the attribute information of node according to obtaining instruction instruction, and property value and structural information are together returned to server.

Fig. 7 is an embodiment of management object address search, concrete, can also be that server sends and obtains order to terminal, hit the mark of carrying management object to be found obtaining, and carry subtree root node URI to be found and indicate the parameter of searching, described in returning, described parameter indicating terminal is identified at the root node URI of the management object on terminal management tree;

Terminal is received to obtain after order and is searched in described URI instructs node and all inner child nodes thereof and meet the node of described mark, and result is returned to server.

In the present embodiment, MO address search specifically can realize by following 3 kinds of modes:

Method 1, carry a certain property value in tree structure returning to management, be specifically divided into again:

1. server sends and obtains (Get) order to terminal, object run node path information on carried terminal device management tree in " Target/LocURI " of Get order element, carry the value filtering information that need to obtain, this value filtering information indicating terminal returns to the property value of the specified attribute of each node in the structural information of the upper subtree taking object run node as root of terminal management tree and this subtree simultaneously.

Can the filtering information form carrying be: <URI>? list=Struct+<property_name>, wherein " Struct " indicating terminal in combination parameter returns to the composition structural information of the upper indicated node of URI of terminal management tree and child node thereof, the URI (being carried in " LocURI ") of the node that its structure is returned by terminal embodies, <property_name> in combination parameter is a certain nodal community name, return to the property value of this attribute of the indicated node of URI and child node thereof in order to indicating terminal, this attribute can be all properties that terminal is supported, as: node type attribute (Type), the access control right attribute (ACL) of node, the nodal value attribute of a configuration (Format), the title attribute (Title) of node, nodal value size attribute (Size), modification time stamp attribute (TStamp) or the version property (VerNo) of node etc. of node, use-case is as follows:

2. terminal receives obtaining after instruction of server, according to obtaining, the appointment structural information of subtree is obtained in instruction instruction and the attribute information of node (can verify while obtaining whether this server has the ACL authority of this management node, here specifically refer to Get authority), then property value is together returned to server with structural information.

Attribute information is carried at that in " Result " order corresponding to this Get order, (each different node can be distributed in the different I tem daughter element of Result element, or be distributed in the different Result elements that comprises single Item), this concrete property value can be carried at Result/Item/Data element and return, in " Source/LocURI " element of this " Result " order, carry the parameter of node unified resource location (URI) and instruction Property Name, does it consist of: URI? prop=<property_name>, server receives the structure from node URI analysing terminal management tree specified portions after this order, from? prop=<property_name> part is known Property Name corresponding to the entrained property value of Data, from Data element getattr value, use-case is as follows:

Because the MOID of the upper management object of terminal management tree leaves in the Type attribute of this MO root node, so being set to Type attribute, the <property_name> of combinations thereof parameter can in returning to sub-tree structure, return to MOID all in this subtree.Be specially: server judges obtaining after the Type property value of each node under this subtree, if this node is internal node and its Type property value non-NULL, determine the root node that this node is MO, the Type property value of non-NULL is MOID, and then can from the information of returning, obtain the URI of the root node of this MO.Server is obtaining after the URI of MO, can have for transmission Get order to obtain the more detailed information of node in MO, or directly send administration order.

The method can settlement server cannot be obtained in the mode of non-serializing the problem of a certain particular attribute-value of all management nodes under the upper some management subtrees of terminal management tree in batches, can in obtaining sub-tree structure, obtain some particular attribute-value, reduce the mutual of getattr, improve efficiency, can obtain all management objects under this management subtree by property value being appointed as to Type simultaneously, solve the problem that cannot effectively obtain all management objects under management subtree simultaneously.

Method 2, terminal are searched the root node of specific MO and are returned to the URI of root node, and specific embodiment comprises:

1., server sends and obtains (Get) order to terminal, in the Item/Data element that obtains order, carry the MOID of MO to be found, in Item/Target/LocURI element, carry the parameter that subtree root node URI to be found and instruction are searched, described parameter indicating terminal is searched management object that the MOID that carries in Item/Data element the identifies root node URI in Item/Target/LocURI element terminal management tree tree pointed, carry subtree root node URI to be found and indicate the information format of the parameter of searching to be: URI? list=MO_ROOT, specific instructions example is as follows:

2., terminal is received and in described URI instructs node and all inner child nodes thereof, is searched the node that all ACL of having authorities and its Type property value are the MOID that carries of described Data element after this order, and return results to server, described search procedure is only carried out in internal node (its Format attribute is node), and leaf node is not searched, or terminal is preserved the root node of a <MO, table is hinted obliquely in MOI> storage, after the Get order of receiving server, from this mapping table, quick obtaining is to MO position and return results to server.The method of returning results comprises:

1) if find one or more qualified nodes, return to all results that find by Results order corresponding to this Get, each different node can be distributed in multiple Item daughter elements of Results element, or is distributed in the different Results elements that comprises single Item.Result can be returned to MOID, also can not return to MOID:

In result, carry the return method of MOID: the URI of the node that the Item/Target/LocURI carried terminal of this Results finds, the parameter of simultaneously carrying instruction Type attribute:? prop=Type, and in Item/Data, carry MOID.The return method that carries MOID in result does not limit the quantity of Item in its corresponding Get order, and server can carry multiple Item to search the corresponding MO of multiple MOID in the URI of the example of terminal information in same Get order, and concrete use-case is as follows:

In result, do not carry the return method of MOID: the URI of the node only finding at the Item/Target/LocURI of this Results carried terminal.The return method that does not carry MOID in result requires can only carry an Item in its corresponding Get order, be that server is searched the corresponding MO of a MOID in the URI of the example of terminal information in same Get order, because if carry multiplely, server cannot distinguish which Item returns results corresponding be.Use-case is as follows:

Server is obtaining after the URI of MO, can have for transmission Get order to obtain the more detailed information of node in MO, or directly send administration order.

2) if do not find qualified node, (as: in described Get order, the target URI that searches of instruction points to a leaf node, although or it points to an internal node, but the MO that does not have described MOID to identify in the subtree that this internal node is root), do not return to Result, but in " Status " order corresponding to Get order return state 404 Not found.

Search the root node of specific MO and return in the URI of root node for method 2 terminals, can not specify specific MOID, be there is no Data daughter element under the Item element of Get order, terminal is searched the MOID of all management objects and the URI of this management object root node under described URI instructs node after receiving this order, and return results, described lookup method can be: the node of searching Type property value non-NULLs all in all inner child node (the Format property value that is node is node) of this node, or at mapping table of terminal maintenance, terminal is directly searched after the Get order of receiving server in this mapping table.The method returning results is with the return method that carries MOID in result.

Method 3, server side is safeguarded one and management tree corresponding to terminal, the amendment management tree node order that it sends terminal management tree, as replaced (Replace), copy (Copy), delete (Delete), increase (Add) etc., the server management tree that all corresponding maintenance server is preserved after operation is successfully completed, when needs are known terminal management tree structure, first server obtains the object run null terminator Null tree structure of server side maintenance to determine the URI of object run node, then generate administration order and be handed down to object run terminal.

The method of the present embodiment is difficult to the problem of the position of MO on positioning terminal equipment management tree in order to settlement server, can effectively improve the efficiency of server selection terminal equipment management tree MO position, reduce mutual when bookkeeping, improve the efficiency of management, reduce server and Internet Transmission pressure.

ELEMENT Replace (CmdID, NoResp?, Cred?, Meta?, Item+) and >, i.e. Replace order can be carried multiple Item, with indicating terminal, multiple management tree nodes be carried out to Replace action.Multiple Item need orderly processing sometimes in terminal, and whether processing that sometimes can be unordered to be carried out and determined by server in order, in order can the multiple Item in an administration order to be carried out indicating terminal in order.

As shown in Fig. 8 embodiment, a kind of method of administration order executive mode is provided, comprising:

Server in the administration order sending, carry administration order simultaneously in the instruction carried out in order of multiple subitems;

Terminal is received after described administration order, parses the instruction of described orderly execution, and management node corresponding to the each subitem in described administration order carried out to described administration order action in order.

Concrete, server carries the instruction that Item carries out in order in the administration order that is handed down to terminal, and its method of carrying comprises (taking next Replace order as example, other administration order is similar):

ATTLIST Replace order (Sequence|Any) " Any " >, wherein, the value of order attribute, meaning is as follows: " Any " represents not limit the executive mode of terminal, " Sequence ", represents the execution of indicating terminal order.After adding attribute, example is as follows:

ELEMENT Replace (CmdID, NoResp?, Cred?, Meta?, Order?, Item+) and >

<！ELEMENT?Order(Sequence|Any)>

3., for the Item that will sequentially carry out adds a shell element (be that it is the daughter element of administration order, but be also father's element of Item) simultaneously, shell element is only for telling the element of this shell of terminal to need order to carry out.

Terminal is carried out after instruction in order parsing the Item being carried in Replace order, and order is carried out this Replace order to Item instructs node.

The method of the present embodiment in order to settlement server the multiple object run items in cannot the same administration order of indicating terminal ordered pair carry out the problem of described administration order, make the server executive mode of control terminal to administration order flexibly, reduce and carry out the probability of makeing mistakes.

5, before the management activities of equipment control is carried out, first need to set up the managing conversation of server and terminal room, all administration orders all complete in managing conversation.May take a long time in an action of processing at server or terminal.Or expection needs to send management activities soon, in order to reduce the cost of again setting up session, can maintain current sessions as shown in Fig. 9 embodiment, and a kind of managing conversation maintaining method is provided, and comprising:

Server or terminal are determined need send session maintenance instruction to opposite end time, are sent the message of carrying session maintenance order to opposite end in managing conversation;

Acknowledge message is returned to receiving after described message in opposite end, carries out operation corresponding to described session maintenance.

In the present embodiment, for session has designed two kinds of maintaining methods, specific as follows:

1., for fear of the appearance of conversation situation, can design a session maintenance order.Server or terminal determine need to carry out session maintenance action in (when longer in the specified data processing time), send " SyncML " message to the opposing party, this message is carried session maintenance order, the opposing party replys confirmation.This process can repeat when needed, until session maintenance command transmit leg sends essence administration order to the other side or informs the other side's end session.Contain other administration order if carry in " SyncML " message of session maintenance order, the opposing party can ignore this session maintenance command.

As shown in Figure 10 embodiment, send session maintenance order as example taking server, introduce the flow process (it is similar that terminal sends session maintenance order flow process, repeats no more) of session maintenance:

Step 21: terminal and server both sides authenticate and set up session management;

Step 22: both sides carry out the mutual of other operational orders;

Step 23: server generates administration order or carries out data processing;

Step 24: server sends session maintenance order need to carry out session maintenance time determining;

Step 25: terminal sends session maintenance order acknowledge message, and both sides maintain session, until server section sends new administrative messag, this administrative messag can carry administration order or be the null message that does not carry any administration order;

Step 26: the complete terminal data of server process, generates administration order and send to terminal according to result.

Concrete, session maintenance instruction can be used notification command (" Alert ") order, and for it designs a new type codes " Alert Code ", the implication of code as shown in Table 4:

Table four session maintenance code and corresponding implication

Specific instructions use-case is as follows:

Any other data (as Item) can not be carried in this session maintenance order, and terminal, receiving after the session maintenance order of server transmission, is not done any essence management activities, returns to the acknowledge message of this order, as follows:

This embodiment has solved a side determining the problem that sends session maintenance instruction need to notify the other side to carry out session maintenance time to opposite end, can reduce the abnormal interruption of session, raises the efficiency.

2. be, client/server (Client/Server to the management of terminal equipment, be called for short C/S) pattern, determine whether to issue management activities and issue which kind of management activities by server, server is occupied an leading position, therefore, in equipment control, the end of session is determined by server.

In the embodiment of the present invention, design an order of carrying out specially conversation end instruction, this order sends to terminal by server, this order can be placed on separately in a bag and be handed down to terminal, last group administration order that also can be handed down to terminal with server is handed down to terminal together with being packaged in, if the former terminal receiving normal termination session after this order; If the latter, first terminal carries out other administration order in bag, and at complete rear direct end session, does not return to the execution result of related management order to server.Terminal also can buffer memory the execution result of administration order in last bag, obtain when needed in order to server.The order of this conversation end instruction can be used Alert order to realize, and is required to be specific Code of Alert Command design and is specifically designed to instruction session normal termination: as 1210.

The method that judges conversation end in prior art is if server has sent a null message, terminal end session, and this is indefinite to terminal instruction, is unfavorable for that terminal manages accurately.The accurate management that finishes specially directive command and be beneficial to terminal of the present embodiment design.

6, in terminal, some MO can have Multi-instance, but sometimes only having a MO example comes into force, as: for terminal resource class of operation MO, because terminal resource is limited, there is exclusivity, if so when having multiple MO example, synchronization is even within a period of time, and this resource can only be occupied and be operated (coming into force) by a MO example, and the management activities that server issues by other MO example all can be rejected and return error code 403 or 405 or 500.While existing terminal to have multiple MO example in prior art, server cannot be known the problem that the difficulty of the current example coming into force, management server strengthens.As shown in figure 11, for knowing the come into force method of management object of terminal, comprising:

Terminal distribution terminal resource activates to a management object example or terminal to use a management object example, by this management object example as available management object at present;

Terminal is at management object example described in local record, and server sends and obtains instruction and obtain the terminal management object that comes into force to terminal in managing conversation process, and terminal is returned to the information of the management object that comes into force to described server.

In the present embodiment, indicate the current MO of coming into force example (this MO current occupy and can operating terminal resource) comprise following two kinds of methods:

1., terminal is in one of the local maintenance MO list that comes into force, it is upper that this MO list that comes into force is not embodied in terminal management tree, server is by sending Get order and carry parameter and obtain this data to terminal root node.

Obtaining the parameter that order carries can be carried in Get/Item/Target/LocURI, as: can be designed as:.? list=ActivedResourceMO, terminal is returned to the URI corresponding to the root node of terminal resource and the management object that comes into force, server can carry Data element and return to the specific MO of a certain class with indicating terminal in the Item of this order, the value of Data element is MOID, and use-case is as follows:

2., terminal preserves the MO example information that comes into force on management tree, specifically comprise:

A, on terminal management tree, increase management tree subtree, the URI list at management tree subnumber with all MO root nodes that come into force of preservation terminal.The management subtree increasing as shown in figure 12, the come into force management subtree of MO list of preservation can leave under DevDetail management object, server can directly issue Get order to the child node of ActivatedMO node and obtain its value, can know the terminal MO that comes into force, specific instructions and other node of operation are similar, repeat no more here;

Whether b, in the node attribute values of the root node of management object example, to record this management object example be the MO example that comes into force.Server follows this property value of node to judge whether the MO example of this MO example as coming into force at follow-up this MO that directly obtains.Concrete grammar is as follows:

Expand the structure of the Type property value of existing management object root node, amended value structure can be carried a combined value, and this combined value comprises two field: MOID, Activated or Deactivated, above-mentioned two fields connect with plus sige, and use-case is as follows:

The Type property value of the root node of a certain management object is: MOID+Activated.

Terminal is determined the state that comes into force of the upper management object of terminal management tree, safeguards the Type property value of this management object root node simultaneously.

Server is known coming into force when MO of terminal, sends Get order to obtain its value to the Type attribute of this management object root node, and the value of extracting afterwards Activated/Deactivated field judges whether that this MO example is the MO that comes into force.

The present embodiment has solved the terminal iidentification MO that comes into force, and server obtains the method for the MO that comes into force afterwards, can solve in prior art and cannot identify the MO that comes into force, thereby make cannot rapid positioning operation the come into force problem of MO of server, has improved the efficiency of management.
