A method and device for deploying a virtual core network include: periodically predicting, according to the pre-acquired historical data representing the network element load of the core network, the data representing the network element load of the core network at a future time; when determining, according to the predicted data representing the network element load of the core network at a certain future time, that virtual machine capacity expansion or flexible virtual machine expansion needs to be performed at the future time, calculating a first newly-added virtual machine quantity according to the predicted data representing the network element load of the core network at the future time; and at a certain preset time point before the future time, notifying, by a Network Virtualisation Function Management (NVFM), a Network Virtualisation Function Orchestration (NVFO) to perform virtual machine capacity expansion, where the calculated first newly-added virtual machine quantity is also notified to the NVFO by the NVFM. The embodiments of the present invention can timely and effectively adjust the number of network virtual machines, and improve user experience. |
