Description

A kind of methods, devices and systems of realizing equipment control
Technical field
The present invention relates to the equipment control field, particularly a kind of methods, devices and systems of realizing equipment control by data map.
Background technology
DM (equipment control) standard is the unified standard standard that is used for overall architecture, agreement and the problems such as communication mechanism, fail safe of define equipment management.Equipment control mainly provides the services such as parameter customization, software/firmware download, error diagnosis, system maintenance and personalization of terminal equipment.Terminal equipment such as mobile phone terminal, palmtop PC, notebook computer, embedded device, onboard system etc. are not got rid of any other terminal equipment.
In the prior art, the DM server can carry out Bootstrap (initial guide) to terminal equipment earlier, sets up session connection with terminal equipment again, and the session by between the two reaches administrative purposes.Agreement is unconcerned to the bearing bed of session connection, can be the mobile network, also can be fixed network.But can not set up the equipment of session connection with the DM server for some, or because other reasons is not linked the equipment of DM server, the DM server can't manage then to it.Such as; DMS (device management server) is that mobile operator safeguards, supports the mobile phone terminal of DM function can be connected to DMS, but the mobile phone terminal of digital camera, intelligent appliance, defaulting subscriber etc.; can not directly connect DMS, DMS then can not manage this class smart machine.
At present, the user generally has a plurality of smart machines, and such as mobile phone terminal, digital product, electronic equipment, household electrical appliances etc., the maintenance of a plurality of smart machines will be the cumbersome thing of user.In case hardware, software or other problems appear in certain smart machine, generally can only go the maintenace point of manufacturer to seek redress.If a unified device management platform is arranged, the user uses the smart machine (such as mobile phone terminal) that can conveniently link DMS as the agency, other smart machines (such as digital product) are connected by agent equipment go up DMS, so just can realize the management of device management platform easily all smart machines.The present invention just is being based on this thought, has proposed detailed technical scheme, realizes the management of all smart machines.
In the prior art, the management tree of storing on the terminal equipment can be considered to the interface that a DMS manages terminal equipment by the DM agreement, comprising some basic management object (MO, Management Object), DMS reaches the purpose of control terminal resource by the operation to the management tree object.The overall structure of DM standard such as Fig. 1 support the terminal equipment of DM business function that a DMAgent must be arranged, and be responsible for resolving the content of DM agreement, and DMS is issued the operational order that the bookkeeping command conversion becomes terminal to carry out, and the notice terminal is carried out.Support the equipment of DM business function also must comprise a management tree, management tree is organized into tree with all available management objects in the equipment, all here nodes all have unique URI (Unified Resource Identity, unified resource sign) expression.Figure 2 shows that the management tree structure chart, can send associative operation instruction to the node of management tree,, can realize management device resource by operation to management tree such as Add, Copy, Delete etc. by the DM agreement.The packet structure of this agreement is based on WBXML (Wireless BinaryeXtend Makeup Language, radio binary extend markup language) presentation protocol.The node of management tree may comprise one group of environment configurations parameter in this equipment, dissimilar objects, associative operation and some trigger mechanisms etc.The DM server of DM normalized definition is to the flow process of terminal unit management operation, as shown in Figure 3:
Step 1: server is initiated operational notification to terminal;
Step 2: terminal is initiated initial session and is connected, to server report identity information and facility information;
Step 3: server sends identity information, and issues bookkeeping or interactive operation to terminal;
Step 4: terminal is carried out server operation and is responded operating result;
Step 5: if the not suspended word of this session, repeating step 3 and step 4;
Step 6: server is ended session.
In existing DM standard, DMS must set up session connection with terminal equipment could realize further bookkeeping, such as firmware upgrade, software download, failure diagnosis etc.If terminal equipment can not be set up session connection with DMS, then can not realize corresponding bookkeeping.Such as, the user thinks the software on the number code upgraded camera, and perhaps the intelligent appliance of user's family (as refrigerator, air-conditioning etc.) breaks down, and wish that DMS can diagnose it, but these equipment does not connect DMS, and DMS can't manage these equipment.
The networking cost height.These smart machines can be managed by DMS, must link telecommunication network (fixed network or mobile network) and get on, this just needs equipment to have network savvy, and this has increased the manufacturing cost of equipment undoubtedly.If these smart machines are just supported and being connected of agent equipment (such as mobile phone terminal) (by LAN such as data wire or infrared, bluetooths), manufacturing cost will reduce.
Authentication process complexity.Smart machine is directly managed by DMS, and both sides must be through strict authentication process, and DMS must store the relevant authentication information of numerous smart machines, and this has increased the burden of DMS undoubtedly.If use the agency of mobile phone terminal as smart machine, only need the user to set up smart machine and act on behalf of reliable authentication between the mobile phone terminal, can be by the authentication of unified externally foundation of mobile phone terminal and DMS, DMS does not need to store the authentication information of extra smart machine.
Be unfavorable for charge.Certainly, the diagnosis of at present a lot of smart machines or maintenance business are free, and also some is maintenance cost in the future to be converted the equipment price suffered.If these maintenance service needed charges, a lot of smart machines are sold the back and just can't have been charged to it, if use mobile phone terminal as the agency, can withhold in mobile phone charge, will make charge become convenient and easy.
The invention provides and a kind ofly possess by the agency of the equipment of device management server bookkeeping, realize the bookkeeping of equipment management system all smart machines as other smart machines by use.

Embodiment
Core of the present invention is the data message mapping of first equipment of realizing and second equipment room, and realizes the management of device management server to first equipment by second equipment as the agency.Wherein, first equipment is to realize by acting on behalf of being connected in second equipment with the data message mapping of second equipment, this connection of second equipment utilization agency reads the data message of first equipment and the management object of this data message as second equipment is stored on the management tree of second equipment, device management server is issued to first equipment by second equipment from this connection agency with bookkeeping, finish bookkeeping by first equipment, perhaps device management server is issued to second equipment with bookkeeping, by second equipment first device data information under the management tree is managed operation, the data message after will operating by this connection agency again writes first equipment.
Wherein, be the equipment of indication in DM (equipment control) agreement as second equipment of acting on behalf of, comprise mobile phone terminal, palmtop PC, notebook computer, embedded device etc.And first equipment of saying here mainly is at not possessing the smart machine that network function does not connect network, or because other reasons is unwilling to link the smart machine on the network, as arrearage, do not have DM Agent etc., certainly for the smart machine that possesses these functions, the present invention is suitable for too.Device management operations comprises parameter configuration, firmware update, software download, diagnostic monitoring etc.
In order to make those skilled in the art person better understand the present invention program, the present invention is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 4, Fig. 4 shows equipment control flow process of the present invention, may further comprise the steps:
Step 401: first equipment and second equipment connect.
Being connected between first equipment and second equipment can connect by data wire or WLAN (wireless local area network).The connection of data wire can be USB mouth, parallel port, serial ports, netting twine etc., and USB mouth energy plug and play is suitable for the connection that second equipment detects first equipment immediately.WLAN (wireless local area network) can be infrared, bluetooth etc.
Step 402: second equipment is from the first equipment read data information, and data message is stored in the management tree of second equipment as management object.
In the DM standard, the resource on second equipment (firmware, software etc.) all is to exist as the management object on the management tree, and DMS (device management server) can reach the administrative purposes to second equipment by the management object on the DM protocol operation management tree.When first equipment was connected on second equipment, DM Agent on the agent equipment extracted the correlated characteristic information (such as model, firmware version, software information etc.) of smart machine, with these information as the special management object on the management tree.Because, agent equipment needs the data message on the identification intelligent equipment, to guarantee that also these information are that device management server is exercisable, so just the data message of smart machine need be mapped on the management tree of agent equipment, and this mapping must be two-way, if DMS has revised the node on the management tree, the corresponding data information on the smart machine has also been done change.When just being similar to portable hard drive, USB flash disk, digital camera etc. and being connected on the PC by the USB mouth, operating system on the PC with these special installations as a fdisk, the user can increase, revise, delete the file on the special installation by the operation to this subregion.When the user with equipment when the USB mouth of PC removes, its corresponding fdisk has also deleted simultaneously.
When act on behalf of Equipment Inspection to have smart machine connect on the time, will dynamically generate an interim dummy node on its management tree, the related resource of storage smart machine below the node identifies with the URI (unified resource sign) of node.This process can be that bottom firmware, DM Agent or other Agents on the agent equipment finished, and this depends on software and realizes.
Below for the example that dynamically generates interim dummy node on the management tree:
After digital camera (DC, Digital Camera) connected mobile phone terminal, the management object of the related resource on the digital camera promptly appearred on the device management tree of mobile phone terminal.For example, firmware version, firmware data packet etc.The management tree structure is as shown in Figure 5: wherein<Virtual Device〉node can be the original internal node of mobile phone terminal, is used to place the management object relevant with the smart machine that is connected to mobile phone terminal under the node.The having of this node is beneficial to DMS and directly searches under this node, obtains smart machine related management object.Wherein<DC〉node is dummy dynamic node, dynamically produces when digital camera connects mobile phone terminal, disconnect with mobile phone terminal and dynamically delete<DC when being connected node management object down also is to produce simultaneously and delete simultaneously.
The resource of digital camera is different with the position of mobile phone terminal own resources on management tree, can distinguish by URI.For example, the URI of the firmware version of digital camera is: ./VirtualDevice/DC/Firmware/Version.And the URI of the firmware version of mobile phone terminal itself is generally: ./DevDetail/FwV, both URI are different, can distinguish.
Step 403: device management server obtains the data message of first equipment from second equipment, and issues bookkeeping or interactive operation to described second equipment.
After the data message of first equipment was mapped to second equipment, second equipment reported the data message of first equipment to device management server by the DM agreement.Device management server reports the service provider with the data message that obtains by network service interface.The service provider diagnoses according to the data message of receiving and selects suitable bookkeeping to pass to device management server by network service interface according to diagnostic result, and device management server is issued to second equipment with bookkeeping.
Step 404: carry out described bookkeeping or interactive operation and return result.
After acting on behalf of server apparatus and receiving bookkeeping, can do different disposal according to the ability of first equipment.
For the first more weak equipment of ability, the whole reciprocal process between it and the device management server is mainly finished by second equipment.Initiatively obtain the data message of first equipment by second equipment, it is mapped on the dummy dynamic node of management tree, by second equipment data message of first equipment is reported to device management server again, after receiving the bookkeeping that device management server issues, finish device management operations, will operate the back data message again and write first equipment by second equipment.This process can be to cooperate by the DM Agent of first equipment, special-purpose software, bottom firmware or by them with finishing.In this mode, the explanation of DM order is carried out and is finished by second equipment, and first equipment is only supported the proxied device function of reading.It all is to adopt this pattern that present USB flash disk, mp3 etc. link on the PC, and PC can be realized read-write to these equipment, and does not need these equipment to have too many function.This mode than higher, then there is not restriction to first equipment of being acted on behalf of to the requirement of second equipment, only needs to select the second suitable equipment just passable as acting on behalf of.
For the first more intense equipment of ability, can realize by certain connection protocol alternately between them.On second equipment and first equipment bottom firmware and the agent software that is used to be connected are arranged all, this agent software can be DM Agent, also can be special in other agent softwares that connect.If both sides adopt DM Agent as connecting agent software, both can realize alternately by the DM agreement of standard or the DM agreement of simplification, this will make the data message of first equipment more easily be mapped on the management tree of second equipment, also be more convenient for the bookkeeping of DMS to first equipment.In this manner, the operational order that DMS issues can be explained execution by first equipment, and second equipment only provides a passage, and the operational order that DMS issues is given to first equipment.Second equipment can determine that this message is issued oneself according to the URI in the DM message bag or issue first equipment acted on behalf of, this point depends on the specific implementation of DMAgent, from the DMS side, the execution of DM order is transparent, as long as it is just passable to return correct result.
Be digital camera with first equipment now, second equipment is mobile phone terminal, and bookkeeping is that example describes above scheme for upgrading the firmware bag.
At first, the user is connected to digital camera on the mobile phone terminal by LAN such as data wire or infrared, bluetooths, and mobile phone terminal detects digital camera, and digital camera becomes a special management object on the device management tree of mobile phone terminal; The data message of digital camera is mapped under the interim dummy node of mobile phone terminal device management tree, and mobile phone terminal begins with device management server mutual, and its interaction flow comprises the steps: as shown in Figure 6
Step 1: the user submits to the equipment control request to give platform management system (offering service provider's management platform), and the request mode can be make a telephone call to client service center, login Web website etc.Platform management system announcement apparatus management server is carried out associative operation.
Step 2: connect the stage, carry out according to the Setup Phase stage of DM standard.To mobile phone transmit operation notification message, initiate the initial session connection and report relevant information to device management server, comprises identity information etc. by the mobile phone terminal response request by Notification for device management server.
Step 3: the request that the digital camera current version of firmware information that is connected on the mobile phone terminal is obtained in the device management server initiation.
For example, by as issue orders:
<Get>
<CmdID>4</CmdID>
<Item>
<Target>
<LocURI>./Virtual?Device/DC/Firmware/version</LocURI>
</Target>
</Item>
</Get>
Step 3.1: mobile phone terminal returns the current firmware version information of digital camera to device management server.Order as follows:
<Results>
<MsgRef>1</MsgRef><CmdRef>4</CmdRef>
<CmdID>3</CmdID>
<Item>
<Source>
<LocURI>./Virtual?Device/DC/Firmware/version</LocURI>
</Source>
<Data>dc-inc/20050830b/5</Data>
</Item>
</Results>
Step 4: device management server transmits the firmware version information of the digital camera that mobile phone terminal reports to service provider (for example, the manufacturer of digital camera) by WSI (network service interface); The service provider finds that the firmware version of digital camera is low, needs upgrading, and the service provider selects suitable AKU, passes to device management server by the WSI interface; Device management server issues the firmware update bag.
