Patent ID: 8145192

Claim:
A portable terminal device comprising: a radio communicating unit which performs radio communication with a base station device; an incoming call notifying unit which executes an incoming call notification when an incoming call is detected by the radio communicating unit; an incoming call notifying operation controlling unit which controls operation of the incoming call notifying unit; and a radio authenticating unit which conducts radio communication with a radio communicating device and conducts authentication for the radio communicating device in accordance with whether or not a distance to the radio communicating device is within an authentication distance, wherein the incoming call notifying operation controlling unit limits the operation of the incoming call notification of the incoming call detected by the incoming call notifying unit when the distance to the radio communicating device is farther than the authentication distance so as to be more limited than the operation of the incoming call notification of the incoming call detected by the incoming call notifying unit when the distance to the radio communicating device is within the authentication distance, wherein the incoming call notifying operation controlling unit does not execute incoming call notification by the incoming call notifying unit for the incoming call detected when the distance to the radio communicating device is farther than the authentication distance, and wherein the incoming call notifying operation controlling unit includes a storage unit which stores, as non-notified incoming call information, information on the incoming call which is detected when the distance to the radio communicating device is farther than the authentication distance and for which the incoming call notification is not executed by the incoming call notifying unit.
