Detailed Description
The following describes in detail the embodiments of the TR parameter and structure parameter conversion, ACS and CPE communication method and system of the present invention with reference to the drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for converting TR parameters and structure parameters according to an embodiment, including the following steps:
s10, reading the target parameter to be converted, and searching the mapping relation corresponding to the target parameter in a preset XML (Extensible Markup Language) configuration file; the XML configuration file records the mapping relation of TR parameters and structure parameters in one-to-one correspondence; the target parameter is a TR parameter or a structural body parameter;
and S20, acquiring the structural body parameter or TR parameter corresponding to the target parameter from the searched mapping relation, and converting the target parameter into the acquired structural body parameter or TR parameter.
The target parameter may be a TR parameter corresponding to ACS, or a structure parameter on CPE; if the target parameter is a TR parameter, acquiring a structural body parameter corresponding to the TR parameter through the mapping relation, and converting the TR parameter into a structural body parameter corresponding to the TR parameter; if the target parameter is a structural body parameter, the TR parameter corresponding to the structural body parameter needs to be obtained through the mapping relationship, and the structural body parameter is converted into the TR parameter corresponding to the structural body parameter.
On the basis of recording the mapping relation of the TR parameters and the structural body parameters in one-to-one correspondence, the XML configuration file can also record the parameter attribute values of all the parameters (including the TR parameters and the structural body parameters), so that the CPE reads the parameter attribute values corresponding to the TR parameters or the structural body parameters while converting the TR parameters and the structural body parameters by using the XML configuration file, and the accuracy and the integrity of relevant response according to the conversion result are ensured. The code for recording the parameter attribute information under each parameter in the XML configuration file may include:
<Parameter trName＝"Device.DeviceInfo.SerialNumber"structName＝"DeviceInfo"elementName＝"SerialNumber"type＝"unsignedInt"status＝"0"writable＝"true"notification＝"0"/>；
wherein trName is the name of TR parameter; structName is the name of the structural parameter; the elementName is a member name in the structural body parameter; the elementnames under the trName and the structName are in one-to-one correspondence mapping relation; type is a parameter type, e.g., unsignedInt denotes unsigned integer; when the value of status is 0, the validation of the verification and submission is indicated, and when the value of status is 1, the validation and submission is indicated, but the validation and submission is not yet applied, the parameter types can be used in the RPC methods such as SetParameterValues and the like; writeable is a writeable attribute; the notification is an attribute defined in the TR069 protocol. The parameter attribute values of the structure parameters comprise parameter names, parameter values, parameter types, readable and writable attributes of the parameters, Status attributes, Notification attributes and the like; if the TR parameter is a multiple-instance parameter, the parameter attribute value of the TR parameter may further include information such as an instance number of the TR parameter.
The method for converting the TR parameter and the structural parameter provided in this embodiment may preset an XML configuration file that records mapping relationships between the TR parameter and the structural parameter in a one-to-one correspondence manner, and when converting the target parameter, only the corresponding mapping relationship needs to be found in the XML configuration file, so that the conversion from the target parameter to the TR parameter or the structural parameter may be implemented, and the conversion efficiency is high.
In an embodiment, before reading the target parameter to be converted and searching the mapping relationship corresponding to the target parameter in a preset XML configuration file, the method may further include the steps of:
establishing a mapping relation of TR parameters and structure parameters in one-to-one correspondence, and recording the mapping relation as an XML configuration file;
the TR parameter may be set according to a parameter configuration characteristic of the ACS and characteristic information of each CPE managed by the ACS; in a communication system based on TR069, the ACS may remotely control CPEs managed by the ACS by using RPC methods such as SetParameterValues (modified parameter values), GetParameterValues (query parameter values), GetParameterNames (query parameter names), setparameterattatribbles (modified parameter attributes), getparameterattarbutes (query parameter attributes), addobjections (add objects), deleteobjects (delete objects), and the like. The delivered message of the ACS carries the TR parameter and related information of the TR parameter (such as a parameter attribute value, a complete path name or a partial path name, etc.); the TR parameter carried by the delivered message may be a complete path name of the TR parameter or a partial path name of the TR parameter, according to the TR069 protocol, or may be an empty string, where the empty string represents all TR parameters. After reading the TR parameter in the downlink message, the CPE needs to convert the TR parameter into a structural body parameter which can be directly processed, and then responds to the ACS control instruction according to the structural body parameter obtained by conversion.
The structure parameters can be set according to the characteristics of the CPE product, and under normal conditions, the structure parameters on the CPE cannot be directly identified by the ACS, and at this time, the structure parameters need to be converted into corresponding TR parameters, so that the ACS identifies the reported content of the CPE and performs corresponding processing.
As an embodiment, the above-mentioned process of establishing a one-to-one mapping relationship between TR parameters and structure parameters, and recording the mapping relationship as an XML configuration file, that is, before reading target parameters to be converted and searching the mapping relationship corresponding to the target parameters in a preset XML configuration file, may include:
establishing a one-to-one mapping relation between TR parameters and structure parameters;
recording the mapping relation in a two-dimensional table to obtain a parameter mapping table;
and recording the parameter mapping table as an XML configuration file.
In this embodiment, the one-to-one mapping relationship between the TR parameters and the structure parameters may be established by identifying the structure parameters corresponding to each TR parameter, or identifying the TR parameters corresponding to each structure parameter. The method adopts the two-dimensional table to establish the mapping relation of the TR parameters and the structure parameters in one-to-one correspondence for recording, is beneficial to enabling the recorded mapping relation to be clearer and more orderly, and further improves the efficiency of searching the mapping relation through the XML configuration file for converting the target parameters. The two-dimensional table can also record the parameter attribute values of each TR parameter and the structure body parameter so as to improve the integrity of the recorded information, so that the subsequent CPE can read the parameter attribute value corresponding to the processed parameter on the basis of performing parameter conversion by using the XML configuration file without performing other reading work, thereby improving the efficiency of ACS or CPE processing corresponding work.
In an embodiment, the method for converting the TR parameter and the structural body parameter further includes any one or any combination of the following:
the first item:
the TR parameter and the structure parameter each have a parameter identifier; wherein any two parameter identifiers are different; the parameter identifier may be a parameter name or a parameter number, which may uniquely represent a corresponding parameter, and the parameter identifier uniquely corresponds to each TR parameter and structure parameter, and the unique TR parameter or structure parameter may be obtained by using the parameter identifier;
after the target parameter is converted according to the searched mapping relation, the method further comprises the following steps:
when the TR parameter or the structural body parameter is detected to change, identifying the TR parameter with changed content or a parameter identifier corresponding to the structural body parameter as a change identifier, and recording the changed content;
searching the mapping relation corresponding to the change identifier in the mapping relation recorded by the XML configuration file, and further searching TR parameters or structural body parameters with changed contents in the searched mapping relation according to the change identifier;
and changing the searched TR parameter or structural body parameter into changed content.
The second term is:
after the target parameter is converted according to the searched mapping relation, the method further comprises the following steps:
when a newly added parameter is detected, acquiring a matching parameter corresponding to the newly added parameter; the newly added parameters are newly established TR parameters or structural body parameters, and the matching parameters are structural body parameters corresponding to the TR parameters or the TR parameters corresponding to the structural body parameters;
establishing a corresponding relation between the newly added parameters and the matching parameters, and adding the corresponding relation into a mapping relation recorded by the XML configuration file;
and respectively setting the parameter identifiers of the newly added parameters and the matched parameters in the XML configuration file.
The content of the TR parameter or the structure parameter may include the content of the TR parameter or the parameter value of the structure parameter, and the like. When the configuration of the ACS and the CPE managed by the ACS change, the TR parameter corresponding to the ACS also changes, and if the original mapping relationship recorded in the XML configuration file is searched according to the changed TR parameter, the corresponding mapping relationship may not be queried, so that the conversion of the TR parameter is difficult to implement. If the configuration of the CPE changes, the structure parameter corresponding to the CPE is also adjusted accordingly, and at this time, the original mapping relationship recorded in the XML configuration file cannot be queried for the corresponding mapping relationship according to the changed structure parameter, so that it is difficult to implement the above-mentioned conversion based on the structure parameter.
In the embodiment, only the XML configuration file needs to be modified when the TR parameter or the structure parameter is changed, and the program code itself does not need to be modified, which is helpful for the research and development personnel to accelerate the development of the software project and reduce the cost of software development and maintenance. In addition, the new parameters are added into the mapping relation recorded by the XML configuration file, the integrity of the mapping relation recorded by the XML configuration file is ensured, if messages carrying the new parameters are in the communication process of the ACS and the CPE, the XML configuration file can be used for realizing the quick conversion of the new parameters, the content of the messages can be quickly read, the conversion effect of the corresponding parameters is ensured, and the acquisition efficiency of the related message content is improved.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a TR parameter and structure parameter conversion system according to an embodiment, including:
the searching module 10 is configured to read a target parameter to be converted, and search a mapping relationship corresponding to the target parameter in a preset XML configuration file; the XML configuration file records the mapping relation of TR parameters and structure parameters in one-to-one correspondence; the target parameter is a TR parameter or a structural body parameter;
the conversion module 20 is configured to obtain a structural body parameter or a TR parameter corresponding to the target parameter from the found mapping relationship, and convert the target parameter into a corresponding structural body parameter or a TR parameter.
The conversion system of the TR parameters and the structural parameters provided by the invention corresponds to the conversion method of the TR parameters and the structural parameters provided by the invention one by one, and the technical characteristics and the beneficial effects described in the embodiment of the conversion method of the TR parameters and the structural parameters are applicable to the embodiment of the conversion system of the TR parameters and the structural parameters.
Referring to fig. 3, fig. 3 is a flow chart of a communication method of the ACS and the CPE according to an embodiment, which includes the following steps:

and S40, converting the TR parameter into a structural body parameter according to the searched mapping relation, and acquiring the message content issued by the ACS according to the structural body parameter obtained by conversion.
The TR parameter of the ACS can be set according to the parameter configuration characteristic of the ACS and each item of characteristic information of each CPE managed by the ACS; in a communication system based on TR069, the ACS may remotely control the CPE managed by the ACS by using RPC methods such as SetParameterValues (modified parameter values), GetParameterValues (query parameter values), GetParameterNames (query parameter names), setparameteratttributes (modified parameter attributes), getparameteratttributes (query parameter attributes), addobjections (add objects), deleteobjects (delete objects), and the like, during the remote control, the ACS needs to send a message (such as an Inform message carrying a TR parameter) to the CPE, and the ACS sends a message carrying the TR parameter and related information (such as parameter attribute values, a full path name, a partial path name, and the like) of the TR parameter; the TR parameter carried by the delivered message may be a complete path name of the TR parameter or a partial path name of the TR parameter, according to the TR069 protocol, or may be an empty string, where the empty string represents all TR parameters. The CPE reads the TR parameters in the down-sent message, and then the down-sent message is required to be converted into structure body parameters, so that the CPE can directly identify and process the down-sent message, the down-sent message can carry one or more TR parameters, the CPE can identify each TR parameter in the down-sent message, the TR parameters are converted into corresponding structure body parameters according to the mapping relation recorded in the XML configuration file, if the down-sent message carries a plurality of TR parameters, the CPE can also generate a parameter list according to the plurality of structure body parameters obtained by conversion, and the ACS is responded according to the parameter list.
According to the communication method between the ACS and the CPE, when the CPE reads the TR parameters, the mapping relation corresponding to the TR parameters can be searched in the XML configuration file recording the one-to-one mapping relation between the TR parameters and the structure body parameters, so that the rapid conversion from the TR parameters to the corresponding structure body parameters is realized, the efficiency of the CPE identifying the ACS to send the messages is improved, and the communication efficiency between the ACS and the CPE is improved.
In an embodiment, before reading the TR parameter from the delivered message of the ACS and searching the mapping relationship corresponding to the TR parameter in the preset XML configuration file, the method may further include the steps of:
acquiring the XML configuration file;

establishing a mapping relation of TR parameters and structure parameters in one-to-one correspondence, and recording the mapping relation as an XML configuration file;
and acquiring the parameter attribute value of the TR parameter or the structural body parameter, and recording the parameter attribute value under the corresponding TR parameter or structural body parameter in the XML configuration file.
The XML configuration file can be determined in the ACS, can also be determined in the CPE, and can also be constructed by other intelligent control equipment independent of the ACS and the CPE. If the XML configuration file is determined by the ACS or other intelligent control devices, after determining the XML configuration file, the ACS or other intelligent control devices need to send the XML configuration file to the CPE, so that the CPE acquires the XML configuration file.
The above process of recording the parameter attribute values of each parameter (including the TR parameter and the structure parameter) in the mapping relationship of the XML configuration file may be implemented by the following codes:
<Parameter trName＝"Device.DeviceInfo.SerialNumber"structName＝"DeviceInfo"elementName＝"SerialNumber"type＝"unsignedInt"status＝"0"writable＝"true"notification＝"0"/>；
wherein trName is the name of TR parameter; structName is the name of the structural parameter; the elementName is a member name in the structural body parameter; the elementnames under the trName and the structName are in one-to-one correspondence mapping relation; type is a parameter type, e.g., unsignedInt denotes unsigned integer; when the value of status is 0, the validation of the verification and submission is indicated, and when the value of status is 1, the validation and submission is indicated, but the validation and submission is not yet applied, the parameter types can be used in the RPC methods such as SetParameterValues and the like; writeable is a writeable attribute; the notification is an attribute defined in the TR069 protocol. The parameter attribute values of the structure parameters comprise parameter names, parameter values, parameter types, readable and writable attributes of the parameters, Status attributes, Notification attributes and the like; if the TR parameter is a multiple-instance parameter, the parameter attribute value of the TR parameter may further include information such as an instance number of the TR parameter.
And adding corresponding parameter attribute values under the structure parameters recorded by the XML configuration file, so that after the CPE obtains the structure parameters by utilizing the mapping relation conversion recorded by the XML configuration file, the parameter attribute values of the structure parameters can be directly read, the ACS can be directly responded according to the obtained structure parameters and the corresponding parameter attribute values, and the response efficiency can be improved. The parameter attribute value is added under the TR parameter recorded by the XML configuration file, so that the CPE or the ACS can directly read the parameter attribute value of the TR parameter according to the mapping relation recorded by the XML configuration file, the corresponding response speed is accelerated, and the response efficiency is ensured.

The structure parameters of the CPE can be set according to the characteristics of the CPE product, and under normal conditions, if the report message carries the structure parameters, the report message cannot be directly identified by the ACS, at this time, the structure parameters of the CPE can be converted into TR parameters by the CPE, and then the report message is generated according to the TR parameters obtained by conversion, so that after the ACS receives the message reported by the CPE, the TR parameters can be directly obtained from the report message.
In this embodiment, the conversion from the structure parameter to the TR parameter and the acquisition of the corresponding parameter attribute value can be performed on the CPE, so as to generate a parameter list, and send a report message carrying the TR parameter and the corresponding parameter attribute value to the ACS, so that after receiving the report message, the ACS can directly read the TR parameter and the parameter attribute value from the report message, respond to the CPE, and have higher response efficiency.
As an embodiment, in the process of actively reporting the Inform message carrying the TR parameter by the CPE, if the attribute VALUE of the parameter Notification is 2, the CPE needs to actively send a "4 VALUE CHANGE" to the ACS according to the specification of the TR069 protocol, and simultaneously carries the TR parameter and the parameter attribute VALUE. Before sending the Inform message, the CPE may first obtain the structure parameters, read the mapping relationship recorded by the XML configuration file, convert the structure parameters to ParameterList (parameter list) in the TR parameter model according to the one-to-one mapping relationship between the TR parameters and the structure parameters, and then encapsulate the converted ParameterList to the Inform message to be reported and report to the ACS, so that the ACS responds to the Inform message.

The process of recording the parameter attribute values of each parameter (including the TR parameter and the structure parameter) in the mapping relationship of the XML configuration file can be implemented by the following codes:
<Parameter trName＝"Device.DeviceInfo.SerialNumber"structName＝"DeviceInfo"elementName＝"SerialNumber"type＝"unsignedInt"status＝"0"writable＝"true"notification＝"0"/>；
wherein trName is the name of TR parameter; structName is the name of the structural parameter; the elementName is a member name in the structural body parameter; the elementnames under the trName and the structName are in one-to-one correspondence mapping relation; type is a parameter type, e.g., unsignedInt denotes unsigned integer; when the value of status is 0, the validation of the verification and submission is indicated, and when the value of status is 1, the validation and submission is indicated, but the validation and submission is not yet applied, the parameter types can be used in the RPC methods such as SetParameterValues and the like; writeable is a writeable attribute; the notification is an attribute defined in the TR069 protocol. The parameter attribute values of the structure parameters comprise parameter names, parameter values, parameter types, readable and writable attributes of the parameters, Status attributes, Notification attributes and the like; if the TR parameter is a multiple-instance parameter, the parameter attribute value of the TR parameter may further include information such as an instance number of the TR parameter.
And adding corresponding parameter attribute values under the TR parameters recorded by the XML configuration file, so that after the ACS converts the mapping relation recorded by the XML configuration file to obtain the TR parameters, the parameter attribute values of the TR parameters can be directly read, the CPE is directly responded according to the obtained TR parameters and the corresponding parameter attribute values, and the response efficiency is improved.
In one embodiment, after the ACS acquires the XML configuration file, the method may further include the steps of:
acquiring a TR parameter to be issued;
and searching the structural body parameter corresponding to the node TR parameter in the mapping relation recorded by the XML configuration file, generating an issued message of the ACS according to the structural body parameter, and issuing the issued message to the CPE.
The TR parameter in the ACS cannot be directly identified by the CPE, and at this time, the ACS may convert the TR parameter into a structure parameter, and then generate an issue message according to the structure parameter obtained by the conversion, so that the CPE directly obtains the structure parameter after receiving the message issued by the ACS.
As an embodiment, the ACS searches for the structure parameter corresponding to the node TR parameter in the mapping relationship recorded in the XML configuration file, and may also read the parameter attribute value corresponding to the structure parameter, convert the structure parameter and the parameter attribute value into a corresponding parameter list, package the parameter list to the issue message of the ACS, and issue the issue message to the CPE; and the CPE reads the structure body parameters and the parameter attribute values from the received sent messages and responds to the ACS according to the structure body parameters and the parameter attribute values.
In this embodiment, the conversion from the TR parameter to the structure parameter and the acquisition of the corresponding parameter attribute value can be performed on the ACS, so as to generate the parameter list, and send the down message carrying the structure parameter and the corresponding parameter attribute value to the CPE, so that after receiving the down message, the CPE can directly read the structure parameter and the parameter attribute value from the down message, and respond to the ACS, and has higher response efficiency.
