Abstract

CDMA is the main technology which provides an integrated services for the third generation of mobile networks. In UMTS (Universal Mobile Telecommunication Systems), the transmission power is the main share resource among the users. However, the number of users entering the cell is limited by the total interference received at each base station and will vary with time. When the system is congested, admitting a new call can only make the link quality worse for ongoing calls. Therefore, the system needs a call admission policy for new call requests in order to maintain an acceptable QoS connection for existing users. In this paper, the capacity bounds due to interference and power limitations for single service operation have been extracted. Based on these capacity bounds expressions, a Call Admission Control (CAC) algorithm is studied and developed.
