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 for displaying on a display on the mobile station that the mobile station is in a normal idle mode for performing a communication with use of circuit switching for determining when a voice packet communication for the normal idle mode is available, and for receiving a PTT setting instruction for setting a PTT (Push to Talk) mode in which a voice packet communication for the PTT mode is available, the PTT mode operating, at the same time as the normal idle mode, for allowing the determination of when the voice packet communication for the normal idle mode is available while the mobile station is in the PTT mode;
a monitor cycle switching unit for switching, when the PTT setting reception unit receives the PTT setting instruction, the monitor cycle to a predetermined short cycle which is for the PTT mode, the predetermined short cycle being shorter than cycles for other modes; and
a voice reproduction unit for receiving a voice packet which is transmitted from the radio base station after a PTT CALL is detected in the message, and for reproducing a voice based on the voice packet, the PTT CALL being a request for the voice packet communication for the PTT mode.

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.

8. 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 for displaying on a display on the mobile station that the mobile station is in a normal idle mode for performing a communication with use of circuit switching for determining when a voice packet communication for the normal idle mode is available, and for receiving a PTT setting instruction for setting a PTT (Push to Talk) mode in which a voice packet communication for the PTT mode is available, the PTT mode operating, at the same time as the normal idle mode, for allowing the determination of when the voice packet communication for the normal idle mode is available while the mobile station is in the PTT mode; a monitor cycle switching unit for switching, when the PTT setting reception unit receives the PTT setting instruction, the monitor cycle to a predetermined short cycle which is for the PTT mode, the predetermined short cycle being shorter than cycles for other modes; and a voice reproduction unit for receiving a voice packet which is transmitted from the radio base station after a PTT CALL is detected in the message, and for reproducing a voice based on the voice packet, the PTT CALL being a request for the voice packet communication for the PTT mode, the radio base station comprising; a transmission cycle switching unit for switching, 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 for transmitting, to the mobile station, the paging channel slot which stores therein a message which indicates the PTT CALL. - View Dependent Claims (9, 10, 11, 12)

13. A computer-readable recording medium having recorded thereon 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 displaying on a display on the mobile station that the mobile station is in a normal idle mode for performing a communication with use of circuit switching for determining when a voice packet communication for the normal idle mode is available, and for receiving a PTT setting instruction for setting the PTT mode in which a voice packet communication for the PTT mode is available, the PTT mode operating, at the same time as the normal idle mode, for allowing the determination of when the voice packet communication for the normal mode is available while the mobile station is in the PTT mode; a monitor cycle switching step for switching, when the PTT setting instruction is received, the monitor cycle to a predetermined short cycle which is for the PTT mode, the predetermined short cycle being 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 for reproducing a voice based on the voice packet, the PTT CALL being a request for the voice packet communication for the PTT mode.
