Abstract

Call admission control and performance evaluation in wireless communication networks are essential for system design and operation. The network capacity and admissibility of imperfectly power-controlled multiservice code division multiple access (CDMA) system are studied in this paper. A generalized capacity formula considering traffic activity is derived, based on which a handoff prioritized call admission policy is presented and evaluated using the K-dimensional birth-death process model. System performance in terms of blocking probabilities, resource utilization and average system throughput are demonstrated and discussed in detail as the traffic intensity increases. It is also shown that the system parameters such as outage probability constraint and power control error have great impact on system capacity and performance. Since this work is based on the imperfect power control model, it is more appropriate to the design of practical multiservice CDMA networks.
