Descripción: The MBS zone technology is being proposed to develop the system capability and lessen the handoff interruption for wireless Multicast and Broadcast Service (MBS) in a number of Mobile Communications Network (MCN) standards the familiar channel is used to multicast the MBS content to the Mobile Stations (MSs) on the MBS calls within the coverage area of a Base Station (BS), which causes intrusion to the devoted channels serving the established calls, and degrades the system capability. A group of BSs form an MBS zone where the macro diversity is applied in the MS, the BSs coordinate to broadcast the MBS content on the similar common channel in the MBS zone technology, intrusion caused by the familiar channel is condensed, and the MBS MSs need not make handoff while moving between the BSs in the same MBS zone. However, the transmission on the common channel wastes the bandwidth of the BS when there is no MBS MS in a BS with the MBS zone technology. By allowing the QoS for established calls and MBS calls, it is a significant issue to decide the condition for the MBS Controller (MBSC) to enable the MBS zone technology. A two Dynamic Channel Allocation schemes is proposed in this paper: DCA and EDCA by considering the state for allowing the MBS zone technology. Examination and simulation experiments are conducted to explore the performance of DCA and EDCA.
