| Abstract | The next generation wireless networks need to support a wide range of multiservice such as voice, data as well as multimedia with limited radio resources like bandwidth. This research study proposes the channel allocation for overflow calls, wideband (WB) calls and enhancement voice (EV) calls under forced termination and non-forced termination method to analyze the relation among various parameters toward studying the system performance of overflow cellular mobile networks. In this study, the traffic which is lost from primary group is offered to an overflow group. In this study, there are two types of calls; narrowband calls which require one channel and wideband customers, which require more than one channel. In case of bandwidth scarcity, it is unclear whether some of the on-going sessions are degraded to accommodate new incoming sessions, or the new requests be simply denied. Two schemes are considered: forced termination to low priority call and non-forced termination. In forced terminating case, study the forced reduction of bandwidth and call loss in EV calls influenced by wideband calls. Simulation models in overflow and channel allocation strategies are developed with Monte Carlo simulation method. The system performance is investigated in terms of blocking probabilities of each type of calls, forced terminating probabilities, mean carried traffic and system utilization. The results show the system performance is better in non-forced termination method. |
