network management system and method, domain role entity, and operations support system.

摘要

The present invention provides a network management system, device, and method, and relates to the field of communications technologies, so as to resolve a problem that load of an OSS increases because of complex and cumbersome functions of the OSS in an existing NFV architecture. The network management system provided in the present invention includes: an operations support device OSS, a domain function entity, and at least one virtual function node. The OSS is configured to: receive a service request of a user, and send the service request to the domain function entity. The domain function entity is configured to: receive the service request sent by the OSS, obtain an analysis result according to the service request and an analysis algorithm corresponding to the service request, and send the analysis result to a first virtual network function node corresponding to the service request. The first virtual network function node is configured to: perform related processing according to the analysis result sent by the domain function entity, and send a processing result to the domain function entity. The domain function entity is further configured to feed back the processing result to the OSS.
