Management system, overall management node, and management method for managing virtualization resources in a mobile communication network

An overall management node in a management system which is included in a communication system configured to include virtualization resources including a physical server in which a virtual server for executing a communication process is generated and wherein the management system includes a virtual communication-function management node for managing a function of executing the communication process provided in the virtual server, a plurality of virtualization resource management nodes for managing the virtualization resources in mutually different schemes, and the overall management node for managing all the virtualization resources, wherein the overall management node, virtual communication-function management node, and the virtualization resource management node are an orchestrator, virtual network function manager (VNFM), and virtual infrastructure manager (VIM), respectively, which constitute a core network of a mobile communication network, the overall management node comprising circuitry configured to:

• receive a request related to a function of the communication process accompanied by the generation of the virtual server in the physical server, and
• input detailed information for implementing the virtual server on the virtualization resources from the virtual communication-function management node, rewrite the input detailed information according to a scheme in which one of the plurality of virtualization resource management nodes manages the virtualization resources, and request the one of the plurality of virtualization resource management nodes to generate the virtual server on reserved resources necessary for the generation of the virtual server using the rewritten detailed information,
• wherein the virtual communication-function management node is not configured to perform a process in accordance with the schemes, and the schemes, in which the plurality of virtualization resource management nodes manage the virtualization resources, include OPENSTACK or vCenter.

A management method which is a method of operating a management system which is included in a communication system configured to include virtualization resources including a physical server in which a virtual server for executing a communication process is generated and wherein the management system includes a virtual communication-function management node for managing a function of executing the communication process provided in the virtual server, a plurality of virtualization resource management nodes for managing the virtualization resources in mutually different schemes, and an overall management node for managing all the virtualization resources,

• wherein the virtual communication-function management node includes circuitry configured to retain detailed information for implementing the virtual server on the virtualization resources, and
• wherein the management method includes:
• a monitoring step of monitoring, by at least one of the virtualization resource management nodes, a use state of the virtualization resources;
• a reservation step of performing, by the virtualization resource management node, reservation by receiving a request of the reservation of necessary resources for generation of the virtual server among the virtualization resources;
• a virtual server generation step of generating, by the virtualization resource management node, the virtual server by receiving a request for generating the virtual server on the necessary resources for the generation of the virtual server reserved in the reservation step;
• a detailed information output step of outputting, by the virtual communication-function management node, the detailed information retained to the overall management node;
• a request reception step of receiving, by the overall management node, a request related to a function of the communication process accompanied by the generation of the virtual server in the physical server;
• a virtual server generation request step of inputting, by the overall management node, the detailed information from the virtual communication-function management node, rewriting the input detailed information according to a scheme in which one of the plurality of virtualization resource management nodes manages the virtualization resources, and requesting the one of the plurality of virtualization resource management nodes to generate the virtual server on the necessary resources reserved in the reservation step using the rewritten detailed information, wherein the virtual communication-function management node is not configured to perform a process in accordance with the schemes, and the schemes, in which the plurality of virtualization resource management nodes manage the virtualization resources, include OPENSTACK or vCenter;
• and
• a reservation request step of calculating, by the management system, the necessary resources for the generation of the virtual server on the basis of the request received in the request reception step and the use state of the virtualization resources monitored in the monitoring step and requesting the virtualization resource management node to perform the reservation,
• wherein the overall management node, the virtual communication-function management node, and the virtualization resource management node are an orchestrator, virtual network function manager (VNFM), and virtual infrastructure manager (VIM), respectively, which constitute a core network of a mobile communication network.
