The CWMP agreement is as the wide area network management agreement, adopt easy expansion, easy care, intelligible Simple Object Access Protocol (SOAP, Simple Object Access Protocol) protocol encapsulation interaction message, realize extend markup language (XML, Extensible Markup Language) encapsulation and parsing, the data model of supporting by operation CPE is managed the business function that CPE supports, realizes the safe and reliable management to the CPE business.
For the data model that represents the CPE business, protocol definition a series of remote process agreement (RPC, Remote Procedure Call Protocol) method is managed these data models, comprising: the GetParameterNames method of obtaining the data model name, the SetParameterValues method of data model value is set, obtain the GetParameterValues method of data model value, the SetParameterAttributes method of data model attribute is set, obtain the GetParameterAttributes method of data model attribute, add the AddObject method of many instance datas model object and delete the DeleteObject method that realizes the data model object more.
ACS obtains by GetParameterValues RPC method the data model value that cpe device is supported, and then obtains the business function situation of its support, the message encapsulation format of this RPC method as shown in Figure 2:
The message encapsulation mainly is divided into two parts, and a part is message header, for<SOAP-ENV:Header >, a part is message body, for<SOAP-ENV:Body >, message header carries is the unique identification information etc. of this interaction message, and message body is only the real content of this message encapsulation.
The ACS centralized management is scattered in the magnanimity cpe device of user's side, obtains the function situation of CPE business by GetParameterValues RPC method, in existing CWMP technology, also provides the method for obtaining concrete business.The method is obtained concrete business information by instance number, for example, in the time of will inquiring about the wireless user of concrete association, by data model " Device.WiFi.AccessPoint.{i}.AssociatedDevice.{i}. ", go to obtain, when inquiring about concrete user, must " { i} " replace to concrete instance number, as to inquire about the access point instance number be 2, the user that associated wireless user's instance number is 20, the data model of inquiry is " Device.WiFi.AccessPoint.2.AssociatedDevice.20. ".Perhaps, pass through the wireless user of other path query association according to this data model.
Before the concrete business of inquiry, must know the corresponding relation of instance number and concrete business, know such relation, after must at first from CPE, all business being got to ACS, just can know, because instance number is that the variation of following the CPE business changes, the corresponding relation that is instance number and business can only real-time query, by above-mentioned analysis, if inquire about concrete business information by this mode, at first to obtain all business information, draw the corresponding relation of instance number and business information, then go to inquire about concrete business by concrete instance number.
For example, the user expects to inquire about the wireless user that MAC Address is 0011.2233.4455 and is associated on which cpe device, the user can only issue by ACS the operation requests of GetParameterValues method to all cpe devices so, and the data model name is encapsulated as the relative path of " Device.WiFi.AccessPoint. ", CPE situation from associated user to the upper whole MAC Address of ACS feedback CPE, ACS goes to screen the wireless user that MAC Address is 0011.2233.4455 from the message of all CPE feedbacks, finds its associated cpe device.
