Abstract: A mobile terminal is notified of information indicating that an operator pack or the like is downloadable, without need for a user of the mobile terminal to perform any active operation and without need for the mobile terminal to be preliminarily equipped with an extra function for automatic installation. An installation notification system 10 of the present invention includes a mobile terminal 50 and an installation notification server 60 and is provided with an operator pack presence determining unit 15 configured to determine whether an operator pack is present in the mobile terminal 50, based on originating data sent from the mobile terminal 50, and an installation notifying unit 18 configured to notify the mobile terminal 50 of installable information indicating that the operator pack is installable, when the operator pack presence determining unit 15 determines that the operator pack is absent.

Abstract: A cell phone 1 is characterized by having a problem determination storage 3 for storing problem finding information for determining whether there is a problem in received data received by a radio communicator 2, in correspondence to a fixed message, and for storing an arbitrary message available for arbitrary correspondence to the problem finding information; an arbitrary message determination processor 5 for determining whether an arbitrary message is stored in correspondence to the problem finding information in the problem determination storage 3, when it is determined that there is a problem in the received data; and an operation controller 6 for displaying the arbitrary message when the arbitrary message determination processor 5 determines that the arbitrary message is stored, and for displaying the fixed message stored in the problem determination storage 3, when it is determined that no arbitrary message is stored.

Abstract: A mobile device comprises an e-mail receiver for receiving an e-mail indicating that a pattern file for virus disinfection can be updated; an e-mail determination unit for determining model information described in the e-mail received by the e-mail receiver; and a file updater for acquiring a pattern file corresponding to the model information, when the e-mail determination unit determines that the model information related to the mobile device is described.
