Utility-based call admission control for adaptive mobile services

摘要

Limited and time-varying wireless resources, user mobility and various application requirements promote the development of adaptive techniques. Focusing on the cell specific mobility, we 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 traffic and user mobility model. The generality, scalability and computation issues are analyzed and concluded that the proposed solution is independent of application specific utility-bandwidth definition and ongoing user numbers.
