A vast importance is being placed worldwide on the development of third-generation mobile systems where there will be a more complex traffic situation with multi-services. Wideband code division multiple access (CDMA) is emerging as the dominant choice for future third-generation mobile systems. Three different admission control algorithms-received power call admission control (RPCAC), predictive call admission control (PCAC), and a modified predictive call admission control (MPCAC)-were compared in terms of dropping probability, blocking probability, weighted outage and absolute throughput when using four different types of services-speech, video, WWW, and e-mail. Though the MPCAC algorithm offered best performance, the simulations showed that none of the tested algorithms coped well in a multi-service environment
