1. A method for supporting paging in a wireless access system, the method performed by a base station (BS) and comprising:
- receiving a deregistration request message from a terminal that requests initiation of an idle mode;
transmitting a deregistration command message to the terminal in response to the deregistration request message, the deregistration command message including one or more first paging group identifiers for identifying one or more first paging groups assigned to the terminal and one or more paging offsets for the terminal; and
transmitting paging information at a first subframe of a first frame of a superframe during a paging listening interval, the paging information including paging indication information indicating whether or not a paging message exists and one or more second paging group identifiers identifying one or more second paging groups to which the BS belongs,wherein the paging information is used to determine whether at least one of the one or more second paging groups to which the BS belongs is same as one or more first paging groups of terminals located in an area of the BS,wherein the BS transmits the paging message if the paging indication information indicates that the paging message exists, andwherein the BS does not transmit the paging message if the paging indication information indicates that the paging message does not exist.

Abstract
A method for paging in a wireless access system is provided. A method for paging a mobile station of an idle mode includes allocating large paging group identifier and small paging group identifier of a paging group to which the mobile station belongs to a header; allocating a large paging group flag and a small paging group flag to the header, the large paging group flag and the small paging group flag indicating the presence of a paging message for the mobile station; and transmitting the header to the mobile station of the idle mode.

7. A base station (BS) for supporting paging in a wireless access system, the BS comprising:
-
a receiver configured to receive a deregistration request message from a terminal that requests initiation of an idle mode; and a transmitter configured to; transmit a deregistration command message to the terminal in response to the deregistration request message, the deregistration command message including one or more first paging group identifiers for identifying one or more first paging groups assigned to the terminal and one or more paging offsets for the terminal; and transmit paging information at a first subframe of a first frame of a superframe during a paging listening interval, the paging information including paging indication information indicating whether or not a paging message exists and one or more second paging group identifiers identifying one or more second paging groups to which the BS belongs, wherein the paging information is used to determine whether at least one of the one or more second paging groups to which the BS belongs is same as one or more first paging groups of terminals located in an area of the BS, wherein the BS transmits the paging message if the paging indication information indicates that the paging message exists, and wherein the BS does not transmit the paging message if the paging indication information indicates that the paging message does not exist. - View Dependent Claims (8, 9, 10, 11, 12)
