Method for operating control sleep mode in a communication system
First Claim
1. A method for controlling a sleep mode operation by a mobile station (MS) in a communication system, the method comprising:
- receiving, from a base station (BS), a first message that includes data from which a listening interval is detected;
detecting a listening interval based at least in part on the data included in the first message;
operating in an awake state according to the listening interval;
detecting that the listening interval has expired;
in response to detecting that the listening interval has expired, starting a timer for counting a time interval upon detecting that the listening interval has expired; and
maintaining the awake state until the timer expires.

Abstract
A method for controlling a sleep mode operation by a Mobile Station (MS) in a communication system. The MS includes transitioning to an awake state in a listening interval of the sleep mode; performing any one of a first operation, a second operation and a third operation in the awake state; and after any one operation is performed, transitioning to a sleep state upon detecting that there is no data to transmit to the BS and there is no data to be received from the BS. The first operation is a process of receiving data from the BS, the second operation is a process of transmitting data to the BS, and the third operation is a process of receiving data from the BS and receiving data from the BS.

9. A method for controlling a sleep mode operation of a mobile station (MS) by a base station (BS) in a communication system, the method comprising:
-
transmitting, to the MS, a first message that includes data from which a listening interval is detected by the MS; starting a timer for counting a time interval in response to the BS detecting that the listening interval has expired; resetting the timer whenever a second message is received from the MS; if the timer has expired and there is no data to be transmitted to the MS, recognizing that the MS operates in a sleep state; and stopping data transmission for the MS until the MS transitions to an awake state according to a listening interval. - View Dependent Claims (10, 11)

12. A mobile station (MS) in a communication system, the MS comprising:
-
a timer configured to count a time interval; a receiver configured to receive, from a base station (BS), a first message that includes data from which a listening interval is detected; and a control unit configured to detect a listening interval based at least in part on the data included in the first message, to operate in an awake state based on the listening interval, to detect that the listening interval has expired, to start, in response to detecting that the listening interval has expired, the timer upon detecting that the listening interval has expired, and to maintain the awake state until the timer expires. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A base station (BS) in a communication system, the BS comprising:
-
a timer is configured to count a time interval; and a control unit configured to; transmit, to a mobile station (MS), a first message that includes data from which a listening interval is detected by the MS; start the timer in response to the BS detecting that the listening interval has expired; reset the timer whenever a second message is received from the MS; recognize that the MS operates in a sleep state if the timer has expired and there is no data to be transmitted to the MS; and stop data transmission for the MS until the MS transitions to an awake state based on the listening interval. - View Dependent Claims (21, 22)
