To provide a mobile terminal apparatus with the lower communication cost in sending a log at the occurrence of a malfunction, abnormality or fault in the mobile terminal apparatus to a network. A diagnostic process for the malfunction is performed in accordance with a diagnostic policy acquired from the outside. An error code corresponding to the diagnostic result is generated. The generated error code is outputted. With an automatic fault diagnostic function of automatically analyzing the fault in the mobile terminal apparatus without directly sending the log collected in the mobile terminal apparatus to an analytic server, the communication cost can be reduced.

Mobile terminal apparatus and diagnosis method for mobile terminal apparatus

A cell phoneis characterized by having a problem determination storagefor storing problem finding information for determining whether there is a problem in received data received by a radio communicator, 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 processorfor determining whether an arbitrary message is stored in correspondence to the problem finding information in the problem determination storage, when it is determined that there is a problem in the received data; and an operation controllerfor displaying the arbitrary message when the arbitrary message determination processordetermines that the arbitrary message is stored, and for displaying the fixed message stored in the problem determination storage, when it is determined that no arbitrary message is stored.

Information communication apparatus and message displaying method

A download system capable of appropriately spreading loads on a server and on a transmission path, and further enhancing convenience in download of data. A reservation candidate acquirer of a communication terminal acquires from a software managing server reservation candidate information containing time information about time zones as candidates to which a reservation for download of an update file can be allocated. At the communication terminal a user selects a reserved time zone from the time zones corresponding to the time information included in the reservation candidate information, and the software managing server registers the reservation in the reserved time zone. Thereby, the reserved time zone can be selected from the candidate time zones transmitted by the software managing server and the candidate time zones are determined based on a reservation table set so as to spread loads on the software managing server and on the transmission path.
