Network management system, device, and method

A network management method, applied to a domain function entity, the method comprising:

• receiving a service request sent by an operations support system (OSS);
• obtaining an analysis result according to the service request and an analysis algorithm corresponding to the service request;
• sending the analysis result to a first virtual network function node disposed in a device comprising at least one virtual function node that correspond to the service request for processing according to the analysis result;
• and
• receiving a processing result sent by the first virtual function node and sending the processing result to the OSS.

A domain function entity, comprising:

• a communications interface, configured to receive a service request sent by an operations support system (OSS);
• a processor, configured to obtain an analysis result according to the service request received by the communications interface and an analysis algorithm corresponding to the service request;
• and
• wherein the communications interface is further configured to:
• send the analysis result to a first virtual network function node disposed in a device comprising at least one virtual function node that corresponds to the service request for processing according to the analysis result, and
• receive a processing result sent by the first virtual function node, and send the processing result to the OSS.
