US Patent 6889063 Cellular phone having an in-absence incoming call reporting function

A cellular phone of the present invention is capable of displaying an in-absence incoming call message on a display if the user of the phone does not answer an incoming call. At the same time as the in-absence incoming call message is displayed, a timer starts counting a period of time set therein beforehand. A reporting device alerts the user to the incoming call when the timer counts up the preselected period of time. The phone therefore alerts the user to the incoming call not noticed or answered by the user despite that the user carries it.
