Method for supporting bi-directional flow service in IEEE 802.16/WiBro system

The present invention relates to a method for performing, in particular a two-way flow founded relates to a service flow management method for a broadband wireless access communication system. In the IEEE 802.16 / two-way flow service supporting method for a WiBro system provides flow service for IEEE 802.16 / WiBro systems the process according to the invention, the area for designating a two-way flow management information in the standard DSA (Dynamic Service Addition) related messages the step of generating the modified DSA-related message to be allocated; And it characterized in that it comprises the step of running the user terminal and the two-way flow initialization procedure between the base station through a single control message negotiation based on the DSA-related message, the modified.
