Abstract
The Multicast Broadcast Services (MBS) zone technology is proposed to efficiently multicast multimedia content over various Mobile Communication Networks (MCNs). An MBS zone is a group of base stations (BSs) synchronized to transmit the same MBS content using the same radio channel. A significant time delay incurs in the inter-MBS zone handoff, which results in poor QoS of MBS. To reduce the possibility for the inter-MBS zone handoff, we may increase the size of an MBS zone, which however may cause inefficient multicasting channel utilization. This study proposes the OverLapping Scheme (OLS) and the Enhanced OverLapping Scheme (EOLS) for more flexible MBS zone configuration to get better performance for MBS networks in terms of QoS and multicasting channel utilization. We propose the analytical models to model the original MBS zone technology, namely the Basic scheme, and the OLS scheme, which are validated against the simulation experiments based on which we provide more performance metrics for the basic scheme, the OLS scheme, and the EOLS scheme.
