Method and system for controlling sleep mode in broadband wireless access communication system
First Claim
1. A method for controlling a sleep mode including sleep intervals and awake intervals in a broadband wireless access communication system having a base station and subscriber terminals, the method comprising the steps of:
- grouping first subscriber terminals, which request a sleep operation to the base station, into several groups for controlling the sleep mode;
establishing each point of time for transmitting a paging message to each group different from each other within a unit time slot for controlling the sleep mode; and
managing a sleep interval scheduling table, which manages sleep interval scheduling information of each first subscriber.terminal, according to each group in response to a request for a state transition into the sleep mode of the first subscriber terminals.

Abstract
A method and a system is disclosed for controlling a sleep mode in broadband wireless access communication system. The subscriber terminals are managed by grouping the subscriber terminals in a broadband wireless access communication system, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase. A further advantage is provided that each point of time for transmitting a paging message of each group is established differently from each other within a unit time slot for controlling the sleep mode, such that subscriber terminals are managed according to groups. Another advantage is provided that the base station can previously find subscriber terminals awaking at each point of time for transmission the paging message of each other from among subscriber terminals having the sleep mode, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase.

11. A system for controlling a sleep mode including sleep intervals and awake intervals in a broadband wireless access communication system having a base station and subscriber terminals, the system comprising:
-
a grouping part for grouping first subscriber terminals subject to a sleep mode control into predetermined groups;
a management part of a paging message transmission slot of each group for establishing and for managing each different point of time for transmitting a paging message to each group within a unit time slot for controlling a sleep mode;
a transmission/reception part for receiving a sleep request message which represents a request for a state transition into the sleep mode from the subscriber terminals and for transmitting a response message to the first subscriber terminals in response to the request for the state transition into the sleep mode; and
a management part of a sleep interval scheduling table of each group for managing the sleep interval scheduling table of each of the first subscriber terminals in response to the request for the state transition. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
