The network management system includes: an operations support system (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. ## Claims ### Claim 1 A network management system, comprising: an operations support system (OSS) configured to: receive a service request of a user, and send the service request; a domain function entity configured to: receive the service request sent from 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 corresponding to the service request; a first virtual network function node configured to: receive the analysis result sent by the domain function entity and perform related processing according to the analysis result, and send a processing result to the domain function entity; and wherein the domain function entity is further configured to: receive the processing result sent by the first virtual network function node, and feed back the processing result to the OSS. ### Claim 2 (depends on 1) The network management system according to claim 1, wherein the at least one domain function entity comprises at least one of: a mobile domain function entity configured to process a service request of a mobile network; or a fixed domain function entity configured to process a service request of a fixed network. ### Claim 3 (depends on 2) The network management system according to claim 2, wherein the OSS is configured to: determine, according to the received service request, a network type corresponding to the service request; and send the service request to a domain function entity corresponding to the network type, wherein the network type comprises: a mobile network and a fixed network. ### Claim 4 (depends on 1) The network management system according to claim 1, wherein: the at least one virtual function node comprises: at least any one or more of a virtualized network function (VNF), a network functions virtualization infrastructure (NFVI), and a network functions virtualization management and orchestration (NFV MANO); the network management system further comprises an element manager (EM) configured to manage at least one VNF; and the OSS is connected to the domain function entity, and the domain function entity is connected to the EM and the NFV MANO. ### Claim 5 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. ### Claim 6 (depends on 5) The network management method according to claim 5, wherein the domain function entity comprises at least one of: a mobile domain function entity configured to process a service request of a mobile network; or a fixed domain function entity configured to process a service request of a fixed network. ### Claim 7 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. ### Claim 8 (depends on 7) The domain function entity according to claim 7, wherein the domain function entity comprises at least one of: a mobile domain function entity configured to process a service request of a mobile network; or a fixed domain function entity configured to process a service request of a fixed network.
