ABSTRACT:
A cellular phone includes a key input determination unit, key input information storage unit, program storage unit, time decision unit, download execution unit, download execution unit, and program update unit. The key input determination unit determines whether a key input is done, and outputs a determination result as determination information. The key input information storage unit stores every hour the determination information input from the key input determination unit. The program storage unit stores a program. The time decision unit decides time for issuing a program download request to a server, on the basis of the determination information stored in the key input information storage unit when the program stored in the program storage unit needs to be updated. The download execution unit downloads the program at the time determined by the time decision unit. The program update unit updates the program in the program storage unit in accordance with the downloaded program. An automatic program update method for the cellular phone is also disclosed.
