Abstract

Leakage of detailed information for implementing a virtual server to execute a communication process on virtualization resources is prevented. There is provided a management system (10) included in a mobile communication system (1) configured to include an NFVI (60) which is virtualization resources including a physical server generated by a VNF (70) to execute a communication process, and the system includes a VNFM (30) for managing the VNF (70), a VIM (40) for managing the virtualization resources of the NFVI (60), an orchestrator (20) for managing all the virtualization resources of the NFVI (60), wherein the VNFM (30) includes a retention section (31) configured to retain detailed information for implementing the VNF (70) and a virtual server generation request section (32) configured to request the VIM (40) to generate the VNF (70) using the detailed information.
