A mobile terminal retains a communication device allocation priority table in which the allocation priorities of communication devices to respective applications are recorded for each of the communication devices mounted to the mobile terminal. The allocation priorities are determined from the combination of the types of an application and the operation state of the application. The mobile terminal allocates the communication devices to the applications in accordance with the priority orders recorded in the allocation priority table. The allocation priorities recorded in the communication device allocation priority table are varied in accordance with the operation states of the applications and the presence/absence of an alternate device.
