Abstract

The present invention provides a method for performing a ranging process in a broadband wireless communication system. In the method, a ranging request message is transmitted from a mobile station to a base station. A ranging response message including cause information of a ranging status is transmitted from the base station to the mobile station.

Description

[0001] This application is based on the priority of 35U.S.C.§119, which was filed with the Korean Intellectual Property Office on October 25, 2006 and assigned the serial number 2006-104064, and its content is incorporated herein by reference. Technical field [0002] This application relates to a method for performing a ranging process in a broadband communication system, and in particular to a method for handling ranging errors in a broadband communication system. Background technique [0003] The wireless broadband (WiBro) system is based on the Institute of Electrical and Electronics Engineers (IEEE) 802.16e system, and the purpose is to provide a broadband wireless mobile communication system. However, errors may occur in the ranging process between the mobile station (MS) and the base station (BS) in the IEEE 802.16e system. [0004] Figure 1 describes the conventional network entry process between a mobile station (MS) and a base station (BS). The initial ranging process wi...
