摘要：
The main advantage of UMTS radio interface is its flexibility in resource management allowed by the W-CDMA (Wideband Code Division Multiple Access) access technique. However, to exploit this flexibility it is necessary to design an efficient call admission control (CAC) scheme able to adapt the number of active calls in each cell according to interference levels and power availability. In this paper we compare the performance of two CAC styles for voice services, one based on the number of active calls and one on run-time measures of the power emitted by the base station or of the total received interference. For this last class of CAC algorithms we propose a simple scheme that allows to perform measures when silence suppression is adopted.
