Abstract: A communications apparatus includes a first computing circuit and a second computing circuit communicable with the first computing circuit and performing control of wireless communication with a second communications apparatus. The communications apparatus further includes a first storage device that can be written to by the first computing circuit and to which an operation log of the second computing circuit and generated by the second computing circuit is writable via the first computing circuit; a detecting circuit configured to detect a failure in communication between the first computing circuit and the second computing circuit; and a control circuit configured to change a writing destination of the operation log to a second storage device that can be written to by the first computing circuit, when the failure is detected by the detecting circuit.

Abstract: A suspend control apparatus, disposed in an electronic device having a SIM card, includes a control unit that switches the state of the SIM card between a suspended state and a resumed state. The control unit determines, based on the state of SIM card access for data communication and the state of the SIM card when the data communication occurs, whether to give priority to SIM card access or switching to the suspended state, and sets the state of the SIM card accordingly.

Abstract: A cellular terminal device including a memory for storing a received e-mail, a deletion order determiner for determining a deletion order of a plurality of e-mails stored on the memory based on an operation of a user or history information related to a mail sender and a deletion processor for deleting an e-mail stored on the memory in accordance with the deletion order determined by the deletion order determiner.

Abstract: A mobile terminal device includes a communication-setting information storage unit, a validating unit, an emergency-state determining unit, and an emergency notifying unit. The communication-setting information storage unit stores therein communication setting information stored in a removable storage medium. The validating unit validates whether an operator who operates the mobile terminal device is a subscriber. If the validating unit validates that the operator is not the subscriber, the emergency-state determining unit determines that it is an emergency state. If the emergency-state determining unit determines that it is an emergency state, the emergency notifying unit notifies a predetermined emergency contact point of an emergency in accordance with the communication setting information stored in the communication-setting information storage unit.

Abstract: A mobile terminal having detachably mounted thereon a recording medium in which user-specific information is written, and besides the recording medium, having terminal-specific information recorded thereon, the mobile terminal performing radio communication with the recording medium mounted thereon, including: a locking instruction determination section which determines whether or not announcement information transmitted to unspecified mobile terminals by radio communication is locking instruction information containing terminal-specific information to instruct locking of a mobile terminal specified by the terminal-specific information; a coincidence determination section which determines whether or not terminal-specific information contained in the locking instruction information coincides with that recorded on the mobile terminal; and a locking section which locks the mobile terminal to disable at least part of functions of the mobile terminal.
