Method and apparatus for performing uplink ranging in a wireless access system

摘要

The present description relates to a method in which a terminal in an idle mode performs network reentry in a wireless access system, wherein the method comprises: a step of receiving, from a base station, control information containing a first parameter and a second parameter for determining a frame in which uplink ranging is to be performed; and a step of performing uplink ranging for network reentry with the base station on the basis of the control information, wherein the first parameter indicates the location of a superframe in which uplink ranging is to be performed, and the second parameter indicates the frame duration in the superframe which is indicated by the first parameter and in which uplink ranging is performed.

1. A method in which a mobile station in idle mode performs network reentry in a wireless access system, the method comprising:
transmitting a deregistration request (DREG-REQ) message for transitioning from a normal mode to an idle mode; receiving a deregistration response (DREG-RSP) message including control information comprising a first parameter and a second parameter for determining a frame in which uplink ranging is performed, from a base station; transitioning, in response to the reception of the DREG-RSP message, from the normal mode to the idle mode; receiving, in a paging interval of the idle mode, a paging message from the base station; and performing, in response to the reception of the paging message, the uplink ranging for network reentry with the base station based on the first and second parameters in the control information thereby transitioning from the idle mode to the normal mode, wherein the first parameter indicates a position of a superframe in which the uplink ranging is performed, and the second parameter indicates a frame interval in which the uplink ranging is performed in the superframe indicated by the first parameter.
