  • Emergency call code information acquiring system
    Patent number: 8447262
    Abstract: A mobile communication base station transmits broadcast information containing emergency call code information to a mobile terminal with the status “Camped on any cell” defined in the 3GPP specification “TS25.304”. Upon receiving the broadcast information, the mobile terminal acquires emergency call code information from the broadcast information. The status “Camped on any cell” means that a status in which an IC card is uninserted and the mobile terminal is communicable with the mobile communication base station from the perspective of radio wave strength or a status in which an IC card is inserted, the mobile terminal is communicable with the mobile communication base station from the perspective of radio wave strength, and an Attach or location registration to an MSC via the mobile communication base station and an RNC fails.

  • Mobile terminal device, communication system, electric power control method
    Publication number: 20080242371
    Abstract: A mobile terminal device has an electric-power-reduction operation mode for operation with reduced electric power consumption. The mobile terminal device includes an emergency determining unit that determines whether there is an emergency; and an operation mode control unit that controls to shift to the electric-power-reduction operation mode when the emergency determining unit determines that there is the emergency.

  • Information processing apparatus, method and computer product for controlling activation of application
    Publication number: 20070061867
    Abstract: A storing unit stores determining data pertaining to permission of activation of an application. A control unit determines, when an activation request for an application is received, whether activation of the application is permitted based on the determining data, and activates the application when it is determined that the activation of the application is permitted.
