Embodiment Construction

[0040] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Regardless, the same reference numbers are used throughout the drawings to refer to the same or like parts.

[0041] The present invention is implemented in a wireless access system, such as a broadband wireless access system. The invention is also applicable in wireless communication systems operating according to other standards.

[0042] The present invention proposes a method in a wireless access system for optimizing scan request (MOB-SCN-REQ) and scan response (MOB-SCN-RSP) messages so that a mobile station (MS) can measure neighboring base stations ( channel quality of the BS) for handover, optimizing the Dormancy Request (MOB-SLP-REQ) and Dormancy Response (MOB-SLP-RSP) messages exchanged between the MS and the BS to initiate the dormancy mode, and optimizing the Deregistration Request (DREG-REQ) and Deregistration...

Abstract

A method for transmitting messages to alter the operating status between a mobile station and a base station in a wireless access system comprises, at the mobile station, transmitting a first message to the base station, setting a first count to a first predetermined value and enabling a first, the first message requesting a alteration in operating status between the mobile station and the base station, whereupon expiration of the first timer before receiving a second message from the base station, the count is decremented and, if the count is above a second predetermined value, the first timer is reset and the first message is retransmitted to the base station. The method also comprises, at a base station, receiving the first message, transmitting a second message to the mobile station and enabling a second timer, whereupon expiration of the second timer, the alteration in operating status is effected.

Description

technical field [0001] The present invention relates generally to wireless access systems, and in particular to message transmission in wireless access systems. Background technique [0002] Generally, in the development of international standards for broadband wireless access systems, a system of IEEE802.16e includes a mobile station (MS), a base station (BS), and an ASA (Authentication Service Authorization) as an authentication management server. In this case, a common physical layer (PHY) and medium access control (MAC) layer is specified between the MS and the BS. [0003] 1. Scan [0004] figure 1 is a block diagram of an example format of a scan request (eg, MOB-SCN-REQ) message. figure 2 is a block diagram of an example format of a Scan Response (eg, MOB-SCN-RSP) message. The MS requests a scan interval from a currently accessed serving BS to measure the signal quality of neighboring BSs and determine a target BS to be accessed in handover. pass figure 1 The i...
