Abstract :
We propose and analyze a quality-based admission control policy for the integration of voice and data in a CDMA system. 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 specified QoS and the network resources. The system ensures that an accepted call can enjoy its specified QoS without degrading the quality of existing calls. A Markov model is developed to analyze the blocking probability and outage probability. The Erlang capacity of the system can be evaluated
