1. A mobile station which (i) monitors, in a monitor cycle, a paging channel slot which stores a message therein and is transmitted by a radio base station in a transmission cycle, and (ii) performs a process according to the message, comprising:
a PTT setting reception unit operable to receive a PTT setting operation from a user for setting a PTT (Push to Talk) mode, in which a voice packet communication is available; a monitor cycle switching unit operable to switch, when the PTT setting reception unit receives the PTT setting operation, the monitor cycle to a predetermined short cycle which is shorter than a cycle at a time of receiving the PTT setting operation; a voice reproduction unit operable to receive a voice packet which is transmitted from the radio base station after a PTT CALL is detected in the message, and reproduce a voice based on the voice packet, the PTT CALL being a request for the voice packet communication; and a PTT cancel reception unit operable to receive a PTT cancel operation from the user for canceling the PTT mode, wherein when remaining battery charge falls below a predetermined value, the monitor cycle switching unit switches the monitor cycle to a predetermined long cycle which is longer than a cycle at a time of receiving the PTT cancel operation. |
