On the Estimation of User Mobility for Improved Admission Control Algorithms in WCDMA Systems


Abstract—In this work we study Admission Control Threshold in CDMA systems and analyze the already presented algorithms under the point-of-view of QoS metrics. Several points of trade-off can be highlighted and considerations about fairness and gen-erality of these results open up when a more detailed model for mobility is considered. In fact, a simple estimation of the mobility of the users may be used as a useful parameter for the Admission Control scheme, and we show how this can lead to a significant improvement for the system. Thus, a simple but effective way to obtain the improvement is to set up appropriately the admission threshold, and we investigate the direct connection between the threshold value and the point where the QoS trade-off is cut
