The present disclosure aims to provide a core node capable of appropriately allocating a radio resource of a RAN Slice allocated for a specific service to a radio terminal that uses this specific service. A core node () according to the present disclosure includes: a determination unit () configured to determine a radio resource to be allocated in accordance with a service provided for a radio terminal (); and a communication unit () configured to transmit resource identification information indicating the radio resource determined in the determination unit () to a base station () that manages a plurality of radio resources for each RAN Slice associated with a service.

Provided a management apparatus including a maintenance mode setting unit that transitions a first virtualization infrastructure (NFVI0) to a maintenance mode, a mobility control unit that at least instructs a virtualization deployment unit (VDU) on the first virtualization infrastructure in the maintenance mode to move to a second virtualization infrastructure (NFVI1), and a maintenance mode release unit that releases the maintenance mode of the first virtualization infrastructure (NFVI0).

Management of network functions virtualization and orchestration apparatus, system, management method, and program

A control apparatus comprises first to third parts. The first part manages an image, which is information required for execution of a container. The second part requests the third part to start a container corresponding to an image of a predetermined version. The third part instructs the container corresponding to the image of the predetermined version to be created in response to the request from the second part on the basis of the image managed by the first part.

Control apparatus, container starting method, and program

A network functions virtualization management and orchestration system with a VNF descriptor (VNFD) including a information element that allows an instance created based on the VNFD to be distinguished by name. The information element includes an information element of a VM name that describes a naming rule for a virtual machine (VM).

Network functions virtualization management and orchestration method, network functions virtualization management and orchestration system, and program

VNF (Virtual Network Function) descriptor (VNFD) is configured to include an entry that describes a definition of at least one predetermined apparatus connected to each VDU (Virtual Deployment Unit) on a same layer as an information element of the VDU, with a definition element including an apparatus name of the apparatus being provided under the entry and associated with the entry. The VNFD is received from a storage unit storing the VNFD, and an associated instance is created.

The present invention provides a registration management method capable of suppressing influence of data file forwarding load upon processing, and suitable for application to for example VNF Package on-boarding. A data file required for registration is placed in advance on a side of a management apparatus that performs registration processing, and at a registration stage, a registration request is made to the management apparatus by specifying the data file placed on the management apparatus side.
