A Dual Threshold Call Admission Control Algorithm in CDMA Cellular Networks

In this paper, we propose a dual threshold admission control algorithm in voice/data integrated code division multiple access cellular networks. The proposed algorithm gives different threshold to data call, new voice call and handoff call. When a call requests, the proposed algorithm estimates the remained bandwidth and compares it with the threshold to decide if the requesting call is accepted. The simulation shows that the algorithm has the different performance with the different threshold values. We choose the adaptive threshold values through the simulation analysis.
