Embodiment Construction

[0098] Now, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the ensuing description, detailed descriptions of known functions and configurations incorporated herein have been omitted for conciseness.

[0099] The present invention proposes a scheme for fast handover of a mobile subscriber station (MSS) initiated by a handover request from a base station (BS) in an Institute of Electronics and Electrical Engineers (IEEE) 802.16e communication system, wherein the IEEE 802.16e communication system is Broadband Wireless Access (BWA) communication system. Here the IEEE802.16e communication system is a BWA communication system using an Orthogonal Frequency Division Multiplexing (OFDM) and / or Orthogonal Frequency Division Multiple Access (OFDMA) scheme. The IEEE 802.16e communication system, when using the OFDM / OFDMA scheme, can support high-speed data transmission by transmitting physical channel signa...

Abstract

A Broadband Wireless Access (BWA) communication system includes a Mobile Subscriber Station (MSS), a Serving Base Station (BS) with which the MSS performs communication, and a plurality of neighboring BSs. The serving BS transmits to the MSS a handover request message including information on at least one recommended BS to which the MSS can perform handover among neighboring BSs, and indication information indicating fast handover; and to each It is recommended that the BS transmit a handover confirmation message indicating that the MSS will perform fast handover.

Description

technical field [0001] The present invention relates generally to broadband wireless access communication systems, and more particularly, to a system and method for performing fast handover of a mobile subscriber station initiated upon a handover request from a serving base station. Background technique [0002] A fourth generation (4G) communication system, which is a next generation communication system, is currently being studied in order to provide users with services having various qualities of service (QoS) at a transmission rate of about 100 Mbps. More specifically, active research on 4G communication systems is underway in order to support the use in broadband wireless access (BWA) communication systems such as wireless local area network (LAN) systems and wireless metropolitan area network (MAN) systems for securing mobile High-speed service with high reliability and QoS. Conventional communication systems include Institute of Electronics and Electrical Engineers (...
