Abstract: A call control system includes a management device (30) which manages one or more virtual machines (10) operating on a virtualization platform. The virtual machine (10) includes a volume (12) in which an OS, an MW, and an APL which are not updated in operation are installed, a volume (13) in which data which is updated in operation is arranged, and a recovery unit (11) which transmits an image acquisition request for the volume (13) to the management device (30). The management device (30) includes a management unit (31) which creates the virtual machine (10) by arranging an image file including an OS, an MW, and an APL to the volume (12) and arranging an image file including data which is updated while the virtual machine (10) is operating to the volume (13) and a backup unit (32) which backs up the volume (13) as an image file in response to an image acquisition request from the virtual machine (10).

Abstract: An IA server includes a plurality of execution units that execute respective virtual machines of a plurality of disaster recovery stations corresponding one-to-one to a plurality of active stations. The plurality of disaster recovery stations includes a virtualized call control server that performs call processing when an active station is not operating, and a control unit that controls an operation of the virtual machines. The control unit activates, at normal times, the virtual machines, and deactivates, when any active station of the plurality of active stations is not operating, a virtual machine of a disaster recovery station of the plurality of disaster recovery stations other than a virtual machine of a disaster recovery station of the plurality of disaster recovery stations corresponding to the active station not operating, and operates only the virtual machine of the disaster recovery station corresponding to the active station not operating.

Abstract: A duplex operation system including: a plurality of general-purpose devices on each of which a plurality of virtual machines are mounted; and a virtual machine controller that controls a duplex operation performed by two systems, an active system and a standby system, of the virtual machines. When detecting a failure of the active system, the virtual machine controller stops the virtual machine of the active system, activates the virtual machine of the standby system corresponding to the stopped active system, and reconfigures the standby system of the activated virtual machine on the hardware of the stopped virtual machine, and when detecting a failure in the virtual machine of the reconfigured standby system, the virtual machine controller reconfigures the standby system of the failed virtual machine on the general-purpose device 13 different from the general-purpose device 11 in which the virtual machine of the active system has been stopped.

Abstract: A smishing prevention system includes a reception unit that receives an SMS message, a determination unit that determines whether or not a source phone number of the SMS message is a phone number registered in a company information database, a registration unit that registers a determination result in a communication history database, and a presentation unit that presents the determination result to a destination terminal of the SMS message.

Abstract: A virtual machine control device 20 includes: an external disk 22 that has recorded thereon initialization information including user data and application software for each virtual machine 11; and a restart control unit 21 that, when a failure in which a reboot of an OS is executed without a restart escalation for expanding an initialization range in stages occurs in a virtual machine 110 of an active system (ACT), stops a duplexed operation, causes another general-purpose device 10x to load the initialization information for the virtual machine 110 of an active system that has stopped and to reboot an OS and also causes a virtual machine 111 of a standby system (SBY) that has stopped the duplexed operation to load the initialization information for the virtual machine 111 and to reboot an OS, and sets as an active system the general-purpose device 10x that has started up first, and sets as standby system a general-purpose device 101 that has started up later.

Abstract: An IA server (call control apparatus) 31 includes a plurality of execution units 311A to 311C that execute respective virtual machines of a plurality of disaster recovery stations corresponding one-to-one to a plurality of active stations including a call control server that performs call processing at normal times, the plurality of disaster recovery stations including a virtualized call control server that performs call processing when an active station is not operating, and a control unit 312 that controls an operation of the virtual machines of the plurality of disaster recovery stations.

Abstract: A control system including: a first wireless telephone terminal; a second wireless telephone terminal; and a wireless mobile object, wherein the first wireless telephone terminal includes a call placement/reception unit that establishes a voice channel over a mobile communication network with the second wireless telephone terminal and the wireless mobile object by using a multi-point call function of controlling a voice call among a plurality of points, and a control unit that controls the wireless mobile object by transmitting a control signal to the wireless mobile object through the voice channel, and that transmits, to the second wireless telephone terminal through the voice channel, a change signal for changing a user who maneuvers the wireless mobile object when strength of radio waves from the wireless mobile object decreases to less than a threshold value.

Abstract: A wireless mobile object 1 includes: a response unit 32 that responds to a call received through a voice channel over a mobile communication network; and a control unit 36 that controls an action of the wireless mobile object, based on maneuver information received through the voice channel.

Abstract: In an updating method according to the present embodiment, a virtual machine (50-1A) is stopped, a virtual machine (50-1B) is started up using a new VM image (30-1B) to which a link to a database (20-1) is set, and the virtual machine (50-1B) is switched to an active system. A virtual machine (50-0A) is stopped and a virtual machine (50-0B) is started up using a new VM image (30-0B) to which a link to a database (20-0) is set.

Abstract: A reporting device 1 includes: a starting unit 12 that when emergently stopping an elevator, starts a detection device 3 that is installed in the elevator and senses a radio wave emitted by a mobile terminal 5; a reception unit 13 that receives from the detection device 3 a sensing signal indicating that a radio wave from the mobile terminal 5 has been sensed; and a reporting unit 14 that makes a report to an external system 7 when the reception unit 12 receives the sensing signal.

Abstract: Provided is a duplex operation system in which a range where a duplex operation state can be maintained is expanded. A duplex operation system including: a plurality of general-purpose devices 11, 12, 13 on each of which a plurality of virtual machines are mounted; and a virtual machine controller 20 that controls a duplex operation performed by two systems, an active system and a standby system, of the virtual machines.
