Abstract
This is a mobile telephone capable of detecting the position of the other party to communication without having to make more than necessary positioning attempts. The GPS-mounted mobile telephone determines the position of the target party and, when the target party has entered into a notifiable area set around the position determining party, notifies the position determining party of the entrance of the target party into the notifiable area.
The GPS-mounted mobile telephone can be so configured as to estimate the length of time the target party will take to arrive in the notifiable area set around the position determining party, and to determine the position of the target party after the lapse of that estimated length of time.
