A communication apparatus according to the present invention is characterized by including: a first means capable of operating a first network node on a virtual machine; and a second means capable of forwarding a control signal for terminating communication performed via a communication session established between the first network node and a third network node, to a virtual machine operating a second network node, in response to switchover from the first network node to the second network node corresponding to the first network node.

Communication apparatus, communication method, and program

A base station for offloading communication traffic includes: first means for receiving from a communication terminal a message requesting a connection with a wireless network; and second means for determining whether or not a connection between a base station which has received the message from the communication terminal and the communication terminal is possible based on a terminal attribute identified by the message.

Base station, communication terminal, communication method, communication system, and storage medium

A communication apparatus and a communication control method are provided that make it possible to easily relocate communication apparatus while the continuity of a service a mobile terminal is using is maintained. In a communication system including a terminal (), communication apparatuses (A, B) that provide a service to the terminal () each include: a virtual machine () that manages a state of communication with the terminal () by using information on a session for providing the service; and a virtual machine management section () that controls execution of the virtual machine and migration of the virtual machine.

Communication apparatus and communication control method in a communication system

An index calculation unit calculates a periodicity determination index for determining the presence of periodicity on the basis of the differential between each segment of the frequency distribution of input numerical data and a frequency distribution in accordance with a baseline distribution provided ahead of time. A determination unit uses the periodicity determination index calculated by the index calculation unit to determine the presence of periodicity including one or more periodic components present in the numerical data.

Periodicity detection method, periodicity detection device, and periodicity detection program

A communication control method and a communication system are provided that realize traffic offload while reducing the processing load on a base station. A base station in a mobile network includes a gateway (PO-GW) for connecting a mobile terminal (UE) in the mobile network to a packet data network (PDN), and a control function (MME, DNS, HSS) of the mobile network allows the mobile terminal to access the gateway (PO-GW), in response to a request from the mobile terminal to connect to the PDN via the base station.

Communication system and communication control method

A charging control method and system are provided that can reduce the processing load on a function of performing charging control. The charging control system includes a policy and charging rules function (PCRF), a plurality of gateways (P-GWs) each including a policy and charging enforcement function (PCEF), and a relay section including a relay server and a switch that connects the PCRF and the plurality of PCEFs in a hierarchical manner. The PCRF is directly connected to the relay section, whereby the number of sessions is reduced.

Charging control method and system in communication network

A base station apparatus includes a first identification information acquisition unit for acquiring first identification information for identifying a terminal, the terminal being under management of the base station apparatus, a second identification information generation unit for generating second identification information associated with the first identification information acquired by the first identification information acquisition unit, and a terminal identification information notification unit for notifying an external device of the second identification information generated by the second identification information unit as information for identifying the terminal. An external apparatus is notified of identification information generated based on highly confidential first identification information within a base station, so that personalization can be feasible between a terminal and the external apparatus.

Base station apparatus and communication system

A switch is provided between a first network and a second network and an offloading determination unit determines whether or not to offload traffic for the first network, and configures an offload path to bypass the first network for the switch when the offloading is performed. When the traffic is offloaded, the switch forwards a packet to be offloaded to the offload path.

Network system, method, apparatus, and program

A communication apparatus includes display control means for displaying a secret information image containing secret information, and secret information image generation means for, upon receiving a notification signal indicating that a preparation for shooting is completed from another communication apparatus, instructing the display control means to display the secret information image. Note that the display control means displays a predetermined dummy image, and the notification signal is a notification signal indicating that a shooting preparation has been completed based on the dummy image. Further, when the secret information image generation means receives a notification signal indicating that secret information contained in a secret information image is obtained from another communication apparatus, the secret information image generation means instructs the display control means to stop displaying the secret information image.

Communication apparatus and secret information sharing method
