Abstract
The invention relates to the technical field of communications, and discloses a network operation and maintenance system and a method for making the network operation and maintenance system be compatible with message change of a network management system. The method comprises the following steps: after reception of an ASN (Abstract Syntax Notation) message sent by the network management system, acquiring a version of the network management system; acquiring an identifier of a first ASN message having different fields with a corresponding standard ASN message according to the version; and creating the first ASN message, and processing the field values, which are the same as those of the corresponding standard ASN message, of the first ASN message according to the same processing flow of the standard ASN message. Thus, one system can be automatically compatible with message differences among network management systems with different versions, and connections are finished automatically without user intervention during access to the network management system in order to acquire corresponding data. Moreover, application layer codes for processing the ASN messages do not need to be changed, thereby overcoming the defects of difficulty in system maintenance, need of manual intervention and significant message redundancy in the prior art.
