Discontinuous reception method for mobile communication terminal device and mobile communication terminal device
First Claim
1. A discontinuous reception method during standby of a mobile communication terminal device having a push-to-talk system call function, the method comprising:
- waking up discontinuously in a first discontinuous reception cycle when the mobile communication terminal device is not a member of a push-to-talk session; and
waking up discontinuously in a second discontinuous reception cycle that is shorter than the first discontinuous reception cycle when the mobile communication terminal device is a member of the push-to-talk session.

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).

5. A mobile communication terminal device having a push-to-talk system call function, comprising:
-
means for becoming a member of a push-to-talk session;
means for withdrawing from membership of the push-to-talk session; and
a discontinuous reception control unit which wakes up discontinuously in a first discontinuous reception cycle when the mobile communication terminal device is withdrawn from the membership of the push-to-talk session and wakes up discontinuously in a second discontinuous reception cycle that is shorter than the first discontinuous reception cycle when the mobile communication terminal device becomes the member of the push-to-talk session.
