[0010] 3. In the SET, SEQUENCE structure, a certain node may not exist, because the corresponding message node is allowed to be set as OPTIONAL, indicating that it is optional
Class c description messages and ASN.1 messages both show a tree relationship between nodes, and ASN.1 can semantically represent class c messages. If class c describes messages and ASN. The message of 1 is simulated in different ways, and the workload is too large

Embodiment Construction

[0039] At first, the overall technical scheme of concrete realization of the present invention is described:

[0040] 1. Interface specification, the purpose is to realize the grammatical specification of C-like messages and reduce the arbitrariness of natural language definitions.

[0041] 1.1 Specify the position of the variable-length array in the structure relative to the structure after encoding. Generally, there are two possible situations: the first is that the code stream of the variable-length array is placed behind the previous field in the parent structure, that is, its definition in the structure Location. The second is to place an array of variable length at the end of the parent structure. At this time, for the convenience of positioning, some auxiliary structures can be added, and if there are sub-arrays in the array structure, these array structures are required to be arranged in a certain way. Like preorder traversal.

[0042] 1.2 Select the definition of th...

Abstract

The invention relates to an analog processing method of a similar C structure interface message, which has the similar C structure interface message interacted with a measured object. The method also includes that: the similar C structure interface message which achieves interaction by a coding platform and an encoding and decoding rule is interactively converted with a bottom ASN.1 message; a bottom analog of the similar C structure interface message is achieved based on an ASN.1 functional module. The method simulates the similar C language structure message by means of an interface description language ASN.1 without doing an analog operation of a similar C message from a representation of a bottom message structure, and unifies a processing flow with the ASN.1, thereby reducing a workload for development, and reducing the difficulty for making the similar C message and the workload for making message.

Description

technical field [0001] The invention relates to interface message processing, in particular to a method for encoding and decoding interface messages with a C-like structure and a simulation processing method. Background technique [0002] ITU-T M.3010 divides the telecom management layer model into network element layer (NEL), network element management layer (EML), network management layer (NML), service management layer (SML), and transaction management layer (BML). Communication and interaction are required between the same layer or between the upper and lower layers, so there are various communication interfaces. For example, there are the following common interfaces in the SDH network management system, F interface: the interface between GUI and Manager, the F interface adopts the Ethernet mode, and the Ethernet adopts the TCP / IP protocol. Qx interface: the interface between the Agent at the network element layer and the Manager at the network element management layer....
