Description

Data model object deletion identification device and using method thereof

The invention relates to a data model object deletion and identification device and a using method thereof, in particular to a data model object deletion and identification device supporting the TR-069 protocol and a using method thereof.

The CPE WAN Management Protocol (CWMP), also known as the TR-069 protocol, specifies a common framework and protocol for remote gateway configuration of home gateways for use in the home network from the network side. User terminals such as gateways, routers, and computers perform remote centralized management. Each of the user terminals has a data model, and the data model includes a plurality of objects, each of which is a set of parameters capable of realizing a certain function, such as a virtual local area network (VLAN) function. And each object corresponds to an object identification number, which is used to distinguish each object. Each object includes a plurality of parameters, such as a Port Number, a Port Enable, a Port Status, and the like. Generally, when certain objects in the data model are not referenced, they can be deleted. However, the user terminal also needs to identify the deleted object to know which objects are not cited, so as to facilitate subsequent operations, such as when the object to be deleted is subsequently referred to, the object can be quickly established.

Each user terminal is generally provided with a plurality of stacks supporting the TR-069 protocol. The stacks can establish communication with each other by means of a Remote Procedure Call (RPC) protocol. Referring to FIG. 1, a user terminal includes multiple stacks, at least one of which is used for execution. The stack 1 of the delete operation and the stack 2 for storing the objects, when the object to be deleted needs to be identified, the method generally includes the following steps: first, using the stack 1 to obtain the storage in the stack 2 using the GPV (get parameter value) The Instance ID is used to generate a first Instance list and stored in the stack 1. When the object in stack 2 is deleted, it will send a corresponding RPC command to stack 1. At this time, the stack 1 uses the GPV to obtain the object identification number stored in the stack 2 to generate a second object list, and compares the object identification number of the second object list with the object identification number of the first object list. Analysis to obtain the deleted object identification number and identify the object corresponding to the deleted object identification number.

Obviously, the above method must back up the object identification number for comparison analysis, and the operation process is complicated, and the storage space of the stack 1 is occupied, resulting in waste of resources. In addition, if a plurality of objects in the stack 2 are deleted, the operation sequence in which the objects are deleted cannot be recognized, which is inconvenient.

In view of this, it is necessary to provide a data model object deletion and identification device that is simple in process and convenient to operate.

In addition, it is necessary to provide a method of using the above-described data model object deletion and identification device.

A data model object deletion and identification device is configured to identify a deleted object in a data model including a plurality of objects, wherein each pair of objects is a set of parameters for realizing a function, and each object has an object identification number The data model object deletion identification device comprises a stack, The stack includes a database for storing object identification numbers and parameter information corresponding to the plurality of objects, and a service agent for identifying the corresponding objects according to the object identification number information in the database; For determining whether an object identification number is deleted in the database, and a communication module, configured to send a remote program call command to the determining module when determining that the object identification number in the database is deleted A service agent that identifies the corresponding deleted object based on the object identification number information included in the remote program call command.

A method for using a data model object deletion and identification device according to the above item, the method comprising the steps of: a. the service agent performs a signing action on an object associated with the object to transmit the object to the communication module. The identification number information accurately identifies the object corresponding to the object identification number; b. the determining module determines whether an object identification number is deleted in the database; c. if yes, the communication module sends a remote program call command to a service agent, the remote program call command includes an item identification number information of the deleted object; d. the service agent receives the remote program call command, and parses the remote program call command to identify The object corresponding to the object identification number is deleted.

Compared with the prior art, the data model object deletion identification device of the present invention can quickly identify the object identification number information of the deleted object by setting a service agent, once an object in the database is deleted. The corresponding deleted object. The data model object deletion and identification device of the invention does not need to back up the object and its object identification number, and the flow is simple, and the management performance of the data model object deletion and identification device is effectively improved.
