提出了一种适合于话音和数据用户并发的蜂窝CDMA系统的呼叫接纳控制算法。该算法将数据业务，新到达的语音业务，切换的语音业务进行区分对待，设置不同的剩余带宽门限值。当新呼叫或切换呼叫到达时，首先估计当前系统剩余的带宽，然后根据不同类别业务与不同门限值进行比较，决定是否对该呼叫进行接纳。最后通过仿真对门限值的不同设定进行了比较分析。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.
