Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
The conversion method of CWMP and UPnP agreement in a kind of terminal management of the present invention comprises the request message conversion of CWMP agreement and the response message conversion of UPnP agreement.
As shown in Figure 1, the conversion of described request message comprises step:
S11. after home gateway is received the request message of the CWMP agreement that ACS (Auto-Configuration Server, Automatic Configuration Server) sends, message content is resolved.
S12. judge RPC (Remote procedure call, remote procedure call) the method operating data model whether in the request message, if get into S13; If not, get into S14.
S13. convert request message into CMS (ConfigurationManagement Service, configuration admin service) order, get into S15;
S14. convert request message into BMS (BasicManagement Service, basic management service) order, get into S15;
S15. CMS order or BMS order after will changing are packaged into the UPnP protocol massages, send to the UPnP equipment at terminal, and wait for the response message of the UPnP agreement that reception UPnP equipment returns.
Among the said step S13, carry out the conversion between RPC method name and the CMS Action name (Action is an operational order, is meant in the UPnP agreement the various operations to terminal equipment) earlier, carry out the conversion between RPC method and the CMS parameter again.
Corresponding relation between the RPC method of CWMP agreement and the UPnP equipment CMS Action is as shown in table 1:
Table 1
| The RPC method | CMS?Action |
| A1：SetParameterValues | B1：SetValues |
| A2：GetParameterValues | B2：GetValues |
| A3：GetParameterNames | B3：X_CT-COM_GetNames() |
| A4：SetParameterAttributes | B4：SetAttributes |
| A5：GetParameterAttributes | B5：GetAttributes |
| A6：AddObject | B6：CreateInstance |
| A7：DeleteObject | B7：DeleteInstance |
Wherein, the 1st of table 1 is classified data as, is the RPC method of CWMP protocol definition, and these methods all can find the Action one to one that anticipates in the CMS of the 2nd row UPnP equipment, be the implication of various data representatives below:
A1:SetParameterValues is provided with parameter value RPC method, and ACS can revise one or more parameter value of CPE with the method;
A2:GetParameterValues, query parameter values RPC method, ACS can obtain the value of one or more parameters of CPE with the method;
A3:GetParameterNames obtains device parameter model RPC method, and ACS can find that a certain CPE goes up addressable parameter with the method;
A4:SetParameterAttributes revises parameter attribute RPC method, and ACS can change the attribute of the one or more parameters on the home gateway with the method;
A5:GetParameterAttributes query argument attribute RPC method, ACS can read on the home gateway one or the attribute of multi-parameter more with the method;
A6:AddObject adds object instance RPC method, and ACS can set up the new instance of a multi-instance object (multi-instance object) with the method;
A7:DeleteObject, deletion object instance RPC method, ACS can delete the particular instance of an object with the method.
B1:SetValues is provided with parameter value Action, and this order is used for the UPnP control point and revises UPnP device data Model parameter value:
B2:GetValues, query parameter values Action, this order is used for UPnP control point inquiry UPnP device data Model parameter value;
B3:X_CT-COM_GetNames obtains data model Action, and this order is used for instance or the parameter that the UPnP control point obtains the configurable inquiry of UPnP equipment;
B4:SetAttributes is provided with parameter attribute Action, and whether read-only this order be used for the property value (comprise data type, parameter or the instance of parameter etc.) of UPnP control point inquiry UPnP device data model parameter or object;
B5:GetAttributes, query argument attribute Action, this order is used for the property value that the UPnP control point is provided with UPnP device data model parameter or object;
B6:CreateInstance creates object instance Action, and it is new instance of data model Object Creation that this order is used for UPnP control point requirement UPnP equipment;
B7:DeleteInstance, deletion object instance Action, this order is used for the UPnP control point and requires the some instances of UPnP unit deletion (comprising objects all under this instance and parameter).
Has protocol conversion module on the said home gateway; After protocol conversion module is received the RPC method name in the CWMP management request that the ACS that resolved sends; In the 1st row of table 1, seek the method name of coupling, if can find the method name of coupling, then protocol conversion module should be according to this method name position; Find the Action of the 2nd row of going together with it in the table 1, and accomplish the conversion of administration order according to this corresponding relation.
For example: when query argument (A2:GetParameterValues) the RPC method of UPnP facility information is obtained in the ACS transmission; Protocol conversion module finds earlier the position of this RPC method in table 1; Promptly the 1st be listed as the 3rd row; Again in table 1 with this position go together the 2nd row find corresponding Action (B2:GetValues), accomplish the former to the conversion between the latter, i.e. conversion between RPC method name and the CMS Action name.
Transformation rule between said RPC method and the CMS parameter comprises step:
S131. following that type is identical, implication is identical is convertible principle, carries out the conversion of parameter name.
If the RPC method parameter is " title-value (Name-Value) " structure array to form; Then the conversion method of parameter name is: in the RPC method member of the member of parameter list ParameterList parameter and the parameter value in Action request message tabulation ParameterValueList parameter all be Name-Value to form, so need not parametric form is changed.But because parameter list ParameterList is the array of a parameter value structure ParameterValueStruct type, each array member comprises Name (parameter name) and Value (parameter value) two elements; And parameter value tabulation ParameterValueList is the array of a parameter value structure A_ARG_TYPE_ParameterValueList type, and each array member comprises ParameterPath (parameter path) and Value two elements.Therefore, protocol conversion module need convert parameter list member name ParameterValueStruct, Name and the Value in the CWMP message that parses into parameter value tabulation member name Parameter, ParameterPath and the Value in the UPnP protocol massages.
In addition, other non-structure types, but the identical parameter of data type and implication also can be carried out corresponding conversion.For example: the object name ObjectName parameter in the RPC method is character string type with many Instance Names MultiInstanceName parameter in the Action request message and implication is identical; Be used to deposit the multi-instance object pathname; Therefore, protocol conversion module need convert the object name ObjectName parameter name in the CWMP message that parses into the Instance Name MultiInstanceName parameter name in the UPnP protocol massages.
S132. parameter value is changed, comprised the suffix of object path name in internodal space character in the prefix, alternative parameter path of replacement data model pathname and the replacement data model.
The prefix of said replacement data model pathname; UPnP equipment management data model pathname is initial with "/UPnP/DM/ "; " InternetGatewayDevi ce.X_VENDOR-COM_ProxyDevice.DeviceList.{i}. " node of corresponding home gateway, protocol conversion module should be accomplished the replacement of pathname bebinning character.
The prefix of said replacement data model pathname, and internodal space character in the alternative parameter path are promptly accomplished the data model transfer process.UPnP equipment management data model path is with "/" beginning, and directly uses "/" to separate between node, and the data model that meets the CWMP protocol requirement is directly with root node beginning InternetGatewayDevice, and uses ". " to separate between node.Therefore, protocol conversion module should be accomplished additions and deletions of UPnP equipment management data model beginning "/" character in the data model transfer process and the conversion between "/" and ". ".
The suffix of object path name in the said replacement data model, UPnP equipment management data model part path is with the ending of "/" character, and the data model part path that meets the CWMP protocol requirement ends up with ". ".Therefore protocol conversion module should be accomplished the suffix replacement of part path.
S133. if the parameter that parses exists only in the remote procedure calling (PRC) method, then in protocol conversion process directly with its deletion.It is the parameter that the request message from the CWMP agreement parses here.
For example: the key parameter ParameterKey in the RPC method; Be used for whether the ACS tracking parameter upgrades or be sky; But among the Action owing to COS CMS that reports support at UPnP equipment and BMS; Fail to find the parameter of corresponding implication to exist; Therefore protocol conversion module if finding this parameter will directly delete, need not done any corresponding conversion and handle in the CWMP administration order that parses, and does not carry the key parameter ParameterKey among the RPC in the UPnP equipment control Action request message after conversion yet.
Said step S14 converts request message into BMS, need carry out the conversion between RPC method name and the BMS Action command name, and the conversion between RPC method and the BMS command parameter.
Carry out the conversion between RPC method name and the BMS Action command name; As shown in Figure 2; Be home gateway mapping terminal data model, protocol conversion module with the UPnP Action of non-data model access class, long-rangely restart Reboot, factory reset Baseline etc., be mapped to a plurality of subobjects under the ActionList.BMS. node in the CWMP data model; The subobject name is the BMS command name that UPnP equipment reports support, for example: Reboot, Baseline etc.Under aforesaid Action object, also generate some parameters, these parameters are corresponding one by one with input/return parameters of Action, and wherein return parameters is that read-only, input parameter is a read/write properties; Also comprising the Boolean type parameter that can write under the Action object as stated, and called after wake command InvokeAction.ACS is set to 1 through calling the InvokeAction parameter value that parameter value SetParameterValues method Action object is set, and realizes issuing UPnP equipment B MS order.Therefore; If resolve the RPC method for parameter value SetParameterValues method is set; And be provided with in the parameter Name parameter value comprise " InvokeAction " character string simultaneously the Value value equal 1, then need father's namespace node of the InvokeAction in the intercepting Name parameter value pathname to convert UPnP Action command name into.
Conversion between RPC method and the BMS command parameter; If parsing the SetParameterValues method that the RPC request message issues is the BMS order to the UPnP terminal equipment; Name translation in the parameter list that parameter value SetParameterValues method is set that then will parse behind each Name parameter value pathname last ". " number separator is the parameter of importing into of Action request command, and the Value parameter value is the parameter value that imports into of setting.
And the parameter value syntax conversion is regular, and is identical with above-mentioned " conversion between RPC method and the CMS command parameter " method rule.
As shown in Figure 3, said response message conversion comprises step:
S21. after home gateway receives the response message of the UPnP agreement that said UPnP equipment returns, message content is resolved.
S22. judge whether the error code in the corresponding message equals 0,, get into S23 if equal 0; If be not equal to 0, get into S24.
S23. it is successful to prove that said UPnP equipment is carried out request message, and reverse conversion described request message gets into S25.
S24. prove the failure of UPnP equipment execution request message, protocol conversion module is accomplished the conversion of UPnP agreement and CWMP protocol error sign indicating number, gets into S25.
S25. at last order after the reverse conversion or error code are encapsulated in the CWMP protocol responses message, send to ACS.
Among the said step S23; Be reversed the conversion of described request message; It is inverse conversion to above-mentioned S13 step; Transformation rule is basic identical, and wherein discrepant part is following: state (Status) parameter type in the Action response message that UPnP equipment returns is the variable of Status Type A_ARG_TYPE_ChangeStatus for a change, is to comprise to change to submit to
ChangesCommitted and the array of enumerating that changes the two kinds of parameter values of ChangesApplied that come into force.And home gateway returns to the Status parameter type that comprises in the RPC response command of ACS is integer; Its parameter value 0 and 1 is respectively applied for the expression parameter change and enters into force and use or parameter change has been submitted to but do not used; Though the RPC method is different with the Status parameter type among the Action; But on the parameter value implication one by one on the correspondence, therefore, if UPnP equipment returns the Status parameter value when for a change submitting ChangesCommitted to; Protocol conversion module should convert thereof into numerical value 1, returns to ACS as Status parameter value in the RPC response message; When UPnP equipment returned the Status parameter and for a change comes into force ChangesApplied, protocol conversion module should be converted into numerical value 0, returns to ACS as Status parameter value in the RPC response message.
And in the process of inverse conversion, if from the UPnP protocol massages, resolve and exist only in the operational order, then in protocol conversion process directly with its deletion.
In the Action response message that UPnP equipment returns; If response parameter comprises the pathname and visit (Access) property value thereof of node, instance, parameter; Then the Access property value is used to represent that node, instance, parameter pathname refer to the read-write properties of object and parameter, among the parameter information structure ParameterInfoStruct in this attribute and the RPC response method to write (Writable) attribute implication identical.Therefore; Access property value in the Action response message that protocol conversion module need return UPnP equipment is changed; Convert the Access property value into Boolean 1 from character string " read-write (readWrite) "; " read-only (readOnly) " converts Boolean 0 into from character string, and is combined into the ParameterList parameter type ParameterInfoStruct structure array in the RPC response method, returns to ACS.
Instance identification InstanceIdentifier parameter in the Action response message that UPnP equipment returns is the path that comprises the instance number; Protocol conversion module should only keep the numeral before this path ending "/" character, returns to ACS as the instance number InstanceNumber parameter value in the corresponding RPC response message.The leaf node initialization ChildrenInitialization parameter type that comprises in the Action response message that UPnP equipment returns is the initial parameter value tabulation A_ARG_TYPE_ParameterInitialValueList variable of XML structure; Be used to the one or more parameter assignment in the new instance of establishment; But because in the CWMP administration order; The parameter that can not find corresponding implication exists; Therefore protocol conversion module need not to carry leaf node initialization ChildrenInitialization parameter in the Action request message after the CWMP administration order that parses is changed.
Among the said step S24, protocol conversion module only need be accomplished the conversion of UPnP agreement and CWMP protocol error sign indicating number, and the corresponding relation between CWMP error code and the UPnP error code is as shown in table 2:
Table 2
| CWMP?Fault?Codes | UPnP?Error?Codes |
| 9001 | 602，604，606，607，608，609，610，611，612 |

| 9008 | (CMS)706 |
The 1st columns certificate in the table 2; It is the error code type of CWMP protocol definition; When the family gateway is carried out in the CWMP management request process that ACS sends if mistake occurs; Home gateway can return error message according to the error response message form of CWMP protocol definition, and the DTC in the message (FaultCode) element is used to deposit error code, and FaultCode element value is shown in the 1st columns certificate in the table 2.
The 2nd columns certificate in the table 2; When UPnP equipment is being carried out the UPnP management request of sending at the UPnP control point on the home gateway if mistake occurs; Require UPnP equipment to echo according to the UPnP consensus standard and answer message (the response message delivery time that comprises expectation) at 30 seconds internal returns; But can not use output variable to come mistake in communication information, because of output variable can only be used for return data, so UPnP equipment can return error message according to definition error response message format among the UPnP architecture standard UDA 1.0; Error code in the message (errorCode) element promptly is used to deposit error code, and errorCode element value is shown in the 2nd columns certificate in the table 2.
After protocol conversion module parses the errorCode element value in the error response message that UPnP equipment returns, should convert the error code of corresponding CWMP protocol definition into according to the corresponding relation in the last table.
According to step S25, the order after the conversion is packaged into the CWMP protocol massages sends to ACS at last.
The present invention is not limited to above-mentioned execution mode, for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, and these improvement and retouching also are regarded as within protection scope of the present invention.The content of not doing in this specification to describe in detail belongs to this area professional and technical personnel's known prior art.
