Problems solved by technology

For another example, if a message has 4 fields, one of which is used as a keyword, and the other 3 fields are non-keywords, but the user only cares about the comparison of two of them, that is, the non-keyword comparison problem, use the above There is no solution for the mentioned method

Embodiment Construction

[0031] The invention provides a method for comparing ASN.1 messages. For the convenience of explaining the problem, "ASN.1 message" is hereinafter referred to as "message". There are two linked list types in ASN.1 message, set of and sequenceof. Due to their commonality in processing, these two types will be referred to as "list".

[0032] In this embodiment, Snacc is used as the compiling platform of ASN.1, and the comparison of messages in the transmission network management system is an embodiment to further introduce the present invention, but not as a limitation of the present invention. In this embodiment, a tree structure is used to save messages.

Abstract

The present invention relates to a method comparing ASN.1 messages, which includes four steps. Firstly, via an interface, a user gives sorting information needed by the ASN.1 messages waiting to be compared; secondly, two ASN.1 messages waiting to be compared are sorted according to the sorting information; thirdly, the two sorted ASN.1 messages waiting to be compared are converted into specific data structures according to the ASN.1 message structure; fourthly, the two ASN.1 messages waiting to be compared and containing the specific data structures are compared, and the comparison results are produced. The present invention resolves the comparison problem of chain list type messages in the comparison of ASN.1 messages, satisfies the comparison of all types of ASN.1 messages, including the comparison of various complex messages, such as chain list type nesting, and satisfies the personalized requirements of users on the comparison of messages, and users can customize both the keywordand the non-keyword comparison methods, therefore the use is more convenient, applicability is wider, and the consistency comparison in the network administration is more perfect, flexible and reliable.

Description

technical field [0001] The invention relates to a telecommunications management network (TMN, Telecommunications Management Network), in particular to a method and system for comparing ASN.1 messages. Background technique [0002] ITU-T M.3010 divides the telecom management layer model into network element layer (NEL, Network ElementLayer), network element management layer (EML, Element Management Layer), network management layer (NML, Network Management Layer), service management layer ( SML, Service Management Layer), transaction management layer (BML, Business Management Layer). There are different network management systems corresponding to different levels. In these systems, various kinds of information about the same entity often exist at the same time, and maintaining a tight consistency among them is an important task. [0003] Currently, in the layered management model of the telecom management network, the format of data communication between layers is mainly Abs...
