Abstract: A method, an apparatus, and a system for deploying a VNF using NEC are provided. The method is as follows: After receiving first location information sent by a user terminal, a central VNFC sends, to a VNFM, a creation request message that is used to create an edge VNFC, where the creation request message carries the first location information. After receiving the creation request message, the VNFM sends, to a VIM, a first request message that is used to create a virtual machine or a container of the edge VNFC, where the first request message carries the first location information and a mirror of the edge VNFC. In this way, it can be implemented that a deployment location of the edge VNFC is proximate to a user in a NEC scenario, thereby reducing a service delay and improving quality of service.

Abstract: Embodiments of this application provide a common service resource application method, a related device, and a system. The method includes: receiving, by a common service manager (CSM), resource requirement information of a common service required by a virtual network function (VNF); and then requesting, based on the resource requirement information of the common service required by the VNF, a virtualized infrastructure manager (VIM) to allocate a resource required by the common service of the VNF. In some embodiments, the CSM applies to the VIM for the resource of the common service required by the VNF, so as to avoid the VNF not working or service quality deteriorating because the common service has no available resource or resources are insufficient, and to avoid wasting common service resources.
