Bidirectional flow service support mehtod in IEEE 802.16/WiBro system

摘要

Provided is a bi-directional service flow management method in a wideband wireless connection communication system, and more particularly, a method of performing a bi-directional flow establishment. The method of providing a flow service in an IEEE 802.16/WiBro includes: generating a revised dynamic service addition (DSA) related message in which an area for designating bidirectional flow management information is allocated from a standard DSA related message; and performing a bidirectional flow initialization process between a subscriber station (SS) and a base station (BS) via single control message negotiation based on the revised DSA related message.
