“…In previous work in this field that we have examined [4,6,8,13], when the system state is above the threshold and there are only reserved handoff channels free, new call attempts are totally blocked out. This can result in inefficient utilization of network resources, especially when the instantaneous user mobility in the area is low.…”

New approaches are presented to facilitate dynamic radio bandwidth management for mobile communication systems. The aim is achieve an overall high level of QoS for both handoff calls and new calls. At the same time, the utilization of wireless network resources, i.e. the revenues earned by the operator. The simultaneous satisfaction of these two conflicting interests, under varying mobility and network traffic conditions, will be difficult. However, a balanced operation could be obtained by applying two novel approaches in system management. First, apriori information about possible handoffs, in the form of cell transition probabilities could be provided by the mobile, which is based on data collected by the mobile itself. This information is used to make handoff reservation requests in neighboring cells. Second, simultaneously controlling the radio resource reservation and new call admission to the system. This approach controls both the amount of reserved channels and the number of new calls admitted in a dynamic way. A theoretical analysis and a simulation have been used to study these approaches and it has been demonstrated that these approaches perform better then other reported approaches in the literature.

“…The simultaneous use of the dynamic threshold and new calls accept probability leads to high level of QoS and efficient resource utilization. The Markov state transition models for NCR, FCR and DCR can be fOlUld in [4,6,7,8,9]. The last approach analyzed and evaluated is the DRCM that is proposed in this study.…”

In this paper, a dynamic resource management and subscriber profile prediction scheme for mobile communication systems is presented. Using this approach, a high level of QoS for both handoff calls and new calls, and better utilization of wireless network resources has been achieved. The simultaneous satisfaction of these two actually conflicting interests will be due to two key features. First, it is due to the subscriber profile predicted using subscriber data. This apriori information about possible handoffs is provided by the mobile terminal and subsequently used for reservation requests. This information is based on the cell transition probabilities calculated by the mobile itself using collected information during past operations. Second, it is due to a two-way approach implemented in the radio resource reservation and new call admission processes. The two-way approach controls both the amount of reservation and the new call admission process in a highly dynamic way, depending on the subscriber mobility and network traffic conditions.Simulation and analytical results are presented and they indicate that proposed approach is superior to techniques previously reported.

In this paper, we develop a tool for evaluating performance of a heterogeneous mobile network under different traffic conditions. The traffic condition is specified in a cluster of seven heterogeneous base stations, and "wrap-up" cell structure is applied to account for the traffic that crosses the boundary of the cluster. The performance of the network is specified in metrics which can be computed using the algorithm developed. These metrics relate to call rejection, i.e. the blocking of new calls, and the termination of handoff calls, as well as the carried traffic i.e. the expected number of ongoing calls in a station. These metrics are either measured for a single base station in a cluster, or measured for the average over the whole cluster. We apply the algorithm to some hypothetical data and present the numerical results. We also consider approximating a heterogeneous model with a simpler homogeneous model. Through some numerical results, we demonstrate the magnitude of errors that could result in the approximation.
