A new call admission control algorithm is presented and analyzed for CDMA networks supporting multimedia services. Our algorithm uses a criterion based on the average SIR as well as the effective bandwidth of the connections. Handoff requests receive higher priority through resource reservation. The proposed algorithm is easy to implement as it only needs to examine the number of current connections in the cell in order to admit or reject a new connection request. The performance of the algorithm is evaluated in terms of blocking probabilities of new and handoff calls, outage probabilities and system throughput. Our results show that our algorithm achieves performance similar to those published in the literature with considerably less implementation complexity. © 2006 IEEE.
