Apparatus and method for controlling sleep mode in wireless access communication system
First Claim
1. A method for controlling a sleep mode containing a sleep interval and a listening interval in a wireless access communication system containing a base station and subscriber terminals, comprising the steps of:
- a) determining a predetermined number of groups for grouping the subscriber terminals according to type information of a paging interval equal to the sum of the sleep interval and the listening interval; and
b) upon receiving a sleep request message from any one of the subscriber terminals, determining a paging interval type of the subscriber terminal on the basis of the sleep request message and paging interval types of the groups, and registering the subscriber terminal in one group from among the groups.

Abstract
An apparatus and method for controlling a sleep mode in a wireless access communication system. The apparatus determines a predetermined number of groups for grouping at least one subscriber terminal according to type information of a paging interval equal to the sum of the sleep interval and the listening interval, and registers the subscriber terminal in one group from among the groups on the basis of the paging interval type of the subscriber terminal. Upon receipt of the group information, the apparatus controls a base station to pre-recognize a terminal woken up at a predetermined time from among a plurality of terminals entering the sleep mode, resulting in reduction of the number of unnecessary paging message transmissions and improved efficiency of the wireless access communication system.

6. An apparatus for controlling a sleep mode containing a sleep interval and a listening interval in a wireless access communication system, comprising:
-
a grouping unit for determining a predetermined number of groups for grouping subscriber terminals according to type information of a paging interval equal to the sum of the sleep interval and the listening interval;
a transmission/reception unit for receiving a sleep request message (SLP-REQ message) for commanding the subscriber terminals to enter the sleep mode, and transmitting a response message (SLP-RSP message) serving as a response to the sleep request message to a corresponding subscriber terminal; and
a group selector for receiving the sleep request message from the transmission/reception unit, determining a paging interval type of a corresponding subscriber terminal on the basis of sleep request information contained in the sleep request message and paging interval type information of the groups, selecting the same group as in the determined paging interval type, and registering the subscriber terminal corresponding to the selected group. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A method for controlling a sleep mode in a wireless access communication system containing a base station and subscriber terminals, comprising the step of:
increasing a paging interval containing a variable sleep interval by repeating a sleep mode and a predetermined size of listening interval according to an exponent power of 2 of a min-window from a min-window field to a max-window field.
-
15. A method for controlling a sleep mode in a wireless access communication system containing a base station and subscriber terminals, comprising the step of:
counting a paging interval containing a listening interval and a sleep interval at every entry into the sleep mode, and at the same time changing the sleep interval. - View Dependent Claims (16, 17, 18)
