Abstract :
In this paper, we propose a QoS-sensitive admission threshold method for the transmission of the non-real-time data packet in voice/data mixed CDMA systems while guaranteeing the QoS requirements of voice and data calls. The proposed admission scheme fully utilizes the remaining resources after serving the voice users for transmitting non-realtime data packet while meeting the QoS requirements for both services. The system performance of the proposed scheme is measured in terms of the average data throughput, the average delay and the average packet loss probability of data traffic while maintaining the outage probability of voice to be less than the predetermined value. In addition, we investigate the effect of the admission threshold level on the system performances
