Abstract: Femtocell is a small and low power cell to a certain base station and is applicable to all standards, including GSM, CDMA, WCDMA and LTE. The implementation of femtocell helps realize the concept of frequency reuse and reduce the power within each small cell in order to decrease interference and decrease the frequency reuse distance. CAC (Call Admission Control) is a key element to control and manage a network’s access and bandwidth, existing CAC schemes, hard QoS CAC scheme and soft QoS CAC scheme, have performances limited in number of accepted calls, total throughput and satisfaction ratio which are key features to measure CAC (Call Admission Control) schemes. In this paper, a dynamic Soft QoS CAC Scheme is proposed under a femtocell environment. The newly proposed scheme would offer a higher total throughput, a number of accepted calls no less than existing Soft QoS CAC Scheme and a better arrangement of bandwidth which gives better satisfaction ratios for all existing calls in the network.
