With the call handoff occurring more and more frequently in wireless networks, an effective call admission control is increasingly urgent for optimum utility of valuable bandwidth. The traditional guard channel scheme (GC) and its numerous variants cannot adapt to changes in traffic pattern due to their static nature. Recently, the dynamic call admission mechanism using stochastic control are found to be more stable and precise. But, it is still hard to get an effective dynamic call admission mechanism for multiservices. The main challenges with multiple types of traffic are that each has its own requirements of bandwidth, QoS guarantee and handoff rate. In addition, the computational complexity is another challenge. At present, most of the relative studies cope with this problem by setting up multiple dimensions stochastic model with high computational complexity. From this paper, it has found that it is enough to use the proposed single dimension stochastic model to compute the key parameters, such as call dropping probability, admission probability. So the computational complexity is greatly decreased. Numerical results of simulation show that the proposed scheme named OMDCA steadily satisfies the hard constraints on call dropping probability for multiservices while maintaining a very high channel throughput.
