Abstract: A radio base station apparatus includes a processor configured to hold an electronic certificate for a communication carrier and a key pair to be used for authentication of the electronic certificate, for each communication carrier that requests a use of the radio base station apparatus, in a case where a connection request is received from the communication carrier, use the key pair and the electronic certificate for a use communication carrier being the communication carrier that has performed the connection request to authenticate whether or not the use communication carrier is the communication carrier to which a connection to the radio base station apparatus is permitted, and, in a case where an attempt of the authentication succeeds, construct a virtual leased line for connecting the radio base station apparatus with a connection device functioning as an interface with the radio base station apparatus in a communication facility of the use communication carrier, and transfer data in accordance with cont

Abstract: A communication control device includes: a processor configured to: acquire identification information of a communication terminal from the communication terminal that is authenticated by communication via a wide area communication network; and when the identification information is included in a storage storing an information set in which associated are (i) the identification information of the communication terminal and (ii) specific connection unit information indicating a specific connection unit that is predetermined for the communication terminal in a narrow area communication network different from the wide area communication network, perform control such that the communication terminal is connected to the specific connection unit as a connection destination of the communication terminal, based on the specific connection unit information of the information set including the acquired identification information.

Abstract: An anomaly detection system according to the present disclosure includes: an optical fiber (10) configured to detect a state of a metal wire (20) affected by a magnetic force generated between a vehicle (60) and a guideway (50) of a magnetically levitated train; a reception unit (30) configured to receive, from the optical fiber (10), an optical signal including information indicating an effect of the magnetic force received by the metal wire (20); and a detection unit (42) configured to detect an anomaly of the vehicle (60) or the guideway (50) based on the information indicating the effect of the magnetic force received by the metal wire (20), the information being included in the optical signal.

Abstract: A relay system includes a first relay device, a second relay device, a controller, and a route advertisement unit. The second relay device receives route advertisement from the first relay device. If an excess of a number of pieces of routing information registered in a routing table of the second relay device over a maximum number of pieces of routing information registrable in the routing table is predicted, the controller controls a number of pieces of routing information that are to undergo the route advertisement from the first relay device to the second relay device. The route advertisement unit performs the route advertisement to the second relay device after excluding, from pieces of routing information registered in a routing table of the first relay device, a piece of routing information set not to undergo the route advertisement as a result of the control of the number of pieces of routing information by the controller.

Abstract: A communication control apparatus includes a processor configured to performs association between a local network slice which is a network slice installed in a network provided by a wireless communication facility and a wide area network segment configured by grouping an external network which is different from the network provided by the wireless communication facility and is used as a dedicated line, sets a transfer path for data transmitted from a terminal using the local network slice, between the local network slice and the wide area network segment.

Abstract: In a method for manufacturing a semiconductor device, impurity ion is implanted into a semiconductor layer so as to form an ion implantation region in the semiconductor layer, and at least the ion implantation region is turned amorphous. Then, an insulating film is formed on the semiconductor layer at a temperature at which the ion implantation region is not crystallized, and then the semiconductor layer is annealed in a non-oxidizing atmosphere so as to activate the impurity ion implanted into the semiconductor layer.
