Call admission control is a provisioning strategy to limit the number of call connections into the networks in order to reduce the network congestion and call dropping. In wireless networks, another dimension is added call connection dropping or simply call dropping is possible due to the user’s mobility. A good CAC scheme has to balance the call blocking and call dropping in order to provide the desired QoS requirements. Limited and time-varying wireless resources, user mobility and various application requirements promote the development of adaptive techniques. Focusing on the cell specific mobility, I propose a target utility-based rather than call drop probability-based solution to address the QoS stability intra/inter cell and tradeoff between carried traffic and degradation. Prediction and compensation methods are used in the proposed scheme with little assumption of fractal traffic and user mobility mode.
