An object is to provide a control device which can control, in consideration of a traffic characteristic of an application operating between an application server and a communication terminal, traffic or a data amount transferred on a core network. A control device () according to the present example embodiment includes: a communication unit () configured to receive, via a service control device () which authenticates an application server () providing a service for a communication terminal (), information relating to a transmittable data amount determined in the application server (); and a control unit () configured to execute, by using the information relating to the transmittable data amount, traffic control on data transmitted from the communication terminal ().

Control device, communication terminal, control method, non-transitory computer readable medium, MME, and base station for controlling a transmission resource using a communication pattern (CP) parameter

An orchestrating apparatus, comprising: a receiving part that receives virtual resource information attached to a VNF (Virtualized Network Function) from a VNFM (Virtualized Network Function Manager) that generated the VNF; a storage part that stores the virtual resource information in correspondence with the VNF; and a synchronizing part that transmits the virtual resource information corresponding to a designated VNF to a VNFM that has lost correspondence between the VNF and the virtual resource information, and causes the VNFM to restore the virtual resource information assigned to the VNF.

Orchestrating apparatus, VNFM apparatus, managing method and program

A RAN node () receives, from a core network node (), a first identifier that is used by a service, an application, or an edge server () to identify a radio terminal () connected to the RAN node (), and associates the first identifier with a second identifier that is used by the RAN node () to identify the radio terminal (). Further, the RAN node () communicates with the edge server () using the first identifier. It is thus, for example, possible to allow an MEC server (or an MEC application hosted on the MEC server) and a radio access network (RAN) node to directly exchange therebetween a control message regarding a specific radio terminal.

Radio base station, edge server, and methods therein

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 network function virtualization management and orchestration apparatus includes a VIM(s) and an upper entity(ies) of the VIM(s). The VIM(s) performs resource management and control of an NFVI(s) that provides an execution infrastructure(s) for a VNF(s) implemented and virtualized by software that operates on a virtual machine(s). The upper entity(ies) collects resource information about the NFVI(s) from the VIM(s) and determines a virtual machine allocation destination(s) based on the collected resource information about the NFVI(s). The VIM(s) generates a virtual machine(s) at the determined virtual machine allocation destination(s).

A control node () used in connection with a core network () operates to transmit a relocation command message related to a first network node (S) located in the core network () and performing mobility management and bearer management of a plurality of mobile terminals () that have attached to the core network (). The relocation command message causes relocation, from the first network node (S) to at least one second network node (T), of the mobility management and the bearer management for at least one of the plurality of mobile terminals (). This contributes, for example, to relocation of mobility management and bearer management of a plurality of mobile terminals between network nodes regardless of the movement of those mobile terminals.

Control node, network node, and methods performed therein

In one embodiment, a mobile terminal () transmits behavior data of the mobile terminal () to a monitoring server (). The monitoring server () acquires the behavior data of the mobile terminal (), and performs communication with a subscriber server () to update the subscriber data () regarding the mobile terminal () based on the behavior data. The subscriber server () updates a subscriber data () based on the communication with the monitoring server ().
