QoS and channel allocation in integrated voice/data cellular wireless networks

In this work, Call Admission Control Schemes which is one of the efficient resource management techniques are analyzed and proposed a new call admission scheme by using the structure of data allowing available bandwidth allocation over Complete-Partitioning Sharing technique. Voice calls are real-time services and needs fixed bandwidth, on the other hand, data calls are non-real time services and adaptable to work in available bandwidth without a concession made for Quest. It is obtained state-dependent service rates by means of this structure of data and modeled two-dimensional(2-D) Markov Chain to be able to measure performance of the proposed scheme and calculated mathematically performance measurements that is voice/data blocking/dropping probabilities for each state over this model Numerical results show that proposed scheme guaranteed the targeted QoS parameters levels in resource utilization.
