Mobile station, mobile communication system, and program
First Claim
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 for the PTT mode and shorter than cycles for other modes; and
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.

Abstract
A mobile station 100 monitors, in Slotted mode, a Paging Channel Slot in a monitor cycle. The mobile station 100 includes: a user interface 53 which receives a PTT setting operation from a user for setting a PTT (Push to Talk) mode; a PTT communication control unit 51 which transmits an allocation request to the radio base station when the PTT setting operation is received; a slot cycle switching unit 52 which switches, when the PTT setting operation is received, the monitor cycle to a predetermined short cycle which is shorter than a cycle at the time of receiving the PTT setting operation; and a voice signal processing unit 40 which receives a voice packet after a PTT CALL is detected in a message transmitted from the radio base station to the mobile station, and reproduces a voice based on the voice packet.

7. A mobile communication system including:
- (i) a radio base station which transmits, in a transmission cycle, a paging channel slot which stores a message therein; and
(ii) a mobile station which monitors the paging channel slot in a monitor cycle and performs a process according to the message,the mobile station 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 for the PTT mode and shorter than cycles for other modes; and
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, the radio base station comprising;
a transmission cycle switching unit operable to switch, when the PTT mode is applied to the mobile station, the transmission cycle to a predetermined short cycle which is for the PTT mode and shorter than the cycles for other modes; and
a PTT CALL transmission unit operable to transmit, to the mobile station, the paging channel slot which stores therein a message which indicates the PTT CALL.
- (i) a radio base station which transmits, in a transmission cycle, a paging channel slot which stores a message therein; and
-
8. A program for instructing a mobile station to execute a communication process with use of a PTT (Push to Talk) mode, the mobile station (i) monitoring, 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) performing a process according to the message, wherein
the communication process includes: -
a PTT setting reception step for receiving a PTT setting operation from a user for setting the PTT mode, in which a voice packet communication is available;
a monitor cycle switching step for switching, when the PTT setting operation is received, the monitor cycle to a predetermined short cycle which is for the PTT mode and shorter than cycles for other modes; and
a voice reproduction step for receiving a voice packet which is transmitted from the radio base station after a PTT CALL is detected in the message, and reproducing a voice based on the voice packet, the PTT CALL being a request for the voice packet communication.
