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.
