Abstract :
We propose and analyze a quality-based admission control policy for the integration of voice and data in DS-CDMA systems. The data users are assigned a higher transmission power level over voice users to achieve a lower bit error rate. The admission policy determines the acceptance of a call request based on its specific quality of service (QoS) and the network resources. The system ensures that an accepted voice call enjoys its specific QoS without degrading the quality of existing voice calls. A power-control-based and a variable-rate-based admission policy are proposed and compared
