N2 - We examine the performance of admission control for the integrated video-conferencing, voice and data services in broadband CDMA networks using analytical methods. The traffic access is based on the Packet Reservation Multiple Access (PRMA) protocol. For the admission control of video-conferencing and voice calls, firstly, we investigate a scheme by introducing a threshold which limits the active subscribers in the network, so that the quality of service (QoS) can be guaranteed. Secondly, we investigate another scheme which uses a Markovian decision process to optimize the performance of voice and video conferencing traffic. The performance of these admission control schemes is evaluated in terms of call blocking probability and idle-slot probability. For data transfer applications, the admission control is investigated under two different schemes: threshold control scheme and graceful degradation control scheme. Their performance is evaluated in terms of throughput, average delay and data packet loss probability.
