Abstract: The decision of call admission becomes an important work with the scarce wireless spectrum for wireless cellular networks. If there exists adequate information for call admission control (CAC) schemes, the terms of quality of service (QoS), such as call dropping probability (CDP), call blocking probability (CBP), and system utilization, will be kept in a certain acceptable level. Therefore, a prediction system which can predict most information, such as system utilization and CDP, in advance with a novel data mining technique and a distributed CAC scheme are presented in this paper. Based on the prediction results and the bandwidth consumptions of adjacent cells, the proposed CAC scheme is able to decide to admit a new call. The throttle flag that can indicate the usage of current cell is proposed to prevent the newly admitted call request from being blocked in adjacent cells if handoff needed. The simulation results show that the proposed CAC scheme can maintain t!
he CDP below a predefined threshold, and the CBP is also lower than traditional guard channel policies.
