Abstract
A discontinuous reception method for a mobile communication terminal device and a mobile communication terminal device which, when a PTT (Push-to-Talk) system call is provided, make it possible to reduce the amount of electrical power consumed by the mobile communication terminal device and to start a PTT-system telephone call with a short wait time. The mobile communication terminal device performs discontinuous reception in a long discontinuous reception cycle in a standby state when the mobile communication terminal device is not a member of a PTT session (step S14) and performs discontinuous reception in a short discontinuous reception cycle in a standby state when the mobile communication terminal device is a member of the PTT session and the PTT call is in a dormant state (step S23).
