In the present embodiment, the specific embodiment of the tree structure is "{" and "}". Therefore, the judging module 406 judges the parameter data one by one by judging whether the parameter includes "{" and "}". Whether the structure is a tree structure.

If the data structure of all the parameters in the RPC command is a tree structure, in step S408, the storage module 414 stores all the parameters and their parameter values in the RPC command in sequence. In the present embodiment, the storage module 414 includes an indicator that initially points to the first parameter.

In step S410, the query module 408 queries the data model for the corresponding object identification number according to the parameter value of each parameter. In this embodiment, the query module 408 matches the parameter value of the parameter with the parameter value of the parameter in the data model. If the query module 408 matches successfully, the object in which the parameter is located is viewed, and the object corresponds to The object identification number is the object identification number corresponding to the parameter.

In step S412, the replacement module 410 replaces the parameter in the storage module 414 with the queried object identification number. In step S414, the determination module 406 determines whether the parameters in the storage module 414 are replaced. In the present embodiment, the determination module 406 determines whether the parameter in the storage module 414 is replaced by the content of the location pointed by the indicator. If the content of the location pointed by the indicator is a number, the replacement is completed, if the indicator points to If the content of the location includes "{" or "}", it means that no replacement has been completed.

If the parameter is not replaced, the process returns to step S410 to continue searching for the object identification number corresponding to the parameter that has not been replaced.

If all the parameters are replaced, then in step S416, the setting module 412 replaces all the parameters of the RPC command with the object identification numbers in the storage module 414.

In the present embodiment, the determination module 406 determines whether the syntax of the set RPC command is correct according to the TR-069 standard. If the syntax of the set RPC command is correct, then in step S420, the query module 408 finds the corresponding object in the data model according to the object identification number in the set RPC command.

At step S422, the processor 416 performs parameter setting on the network device 40 according to the content of the corresponding object to facilitate the management server 10 to provide a new service to the network device 40.

In the present embodiment, if the network device 40 does not support the RPC protocol, the communication module 404 discards the RPC command in step S424.

If the data structure of one of the parameters in the RPC command is not a tree structure, the communication module 404 discards the RPC command in step S424.

If the syntax of the set RPC command is incorrect, then in step S424, the communication module 404 discards the RPC command.

This parameter corresponds to a virtual area network identification number (VLAN ID). When the network device 40 receives the RPC command, it searches for the matching parameter value in the data model IGD according to the value of the VLAN ID; when the matching parameter value is found, the object identification number including the parameter of the VLAN is recorded. {i}. In other embodiments of the invention, network device 40 may simultaneously query a plurality of parameters. It can be seen that the process of the network device 40 finding the object identification number matching the parameter according to the parameter value of the parameter is very simple, and does not occupy too much system resources.

Referring to FIG. 6, a flowchart of an embodiment of the management server 10 of the present invention managing the network device 40 is shown. In the present embodiment, the management server 10 first establishes a TCP connection with the network device 40 and establishes a security mechanism.
