Method for setting sleep interval in a broadband wireless access communication system
First Claim
1. In a broadband wireless access communication system having a sleep mode in which there is no data to be transmitted or received to/from a base station by a subscriber station, and an awake mode in which there is data to be transmitted or received to/from the base station by the subscriber station, a method for setting a next sleep mode by the subscriber station after a sleep interval between a start time of the sleep mode and a start time of the awake mode has reached a given maximum window value, the method comprising the steps of:
- receiving a traffic indication message indicating absence of data to be transmitted from the base station after the start time of the awake mode;
transmitting a sleep request message to the base station;
receiving a response message to the sleep request message from the base station; and
operating in the next sleep mode.

Abstract
A broadband wireless access communication system having a sleep mode in which there is no data to be transmitted or received to/from a base station by a subscriber station, and an awake mode in which there is data to be transmitted or received to/from the base station by the subscriber station. The subscriber station sets a next sleep mode after a sleep interval between a start time of the sleep mode and a start time of the awake mode has reached a given maximum window value. The subscriber station receives a traffic indication message indicating absence of data to be transmitted from the base station after the start time of the awake mode; transmits a sleep request message to the base station; receives a response message to the sleep request message from the base station; and then operates in the next sleep mode.
