Abstract
A communication terminal device which easily provides a call-history function with superior usability. a call history having the same telephone number as the telephone number call-originated has been stored. If it has been stored, the past call history is canceled and the telephone number call-originated is stored as a call history. Thereby, storing call histories from the same party can be prevented increasing the actual number of storable files as call histories.
