提出了一種適合于話音和數(shù)據(jù)用戶并發(fā)的蜂窩CDMA系統(tǒng)的呼叫接納控制算法。該算法將數(shù)據(jù)業(yè)務，新到達的語音業(yè)務，切換的語音業(yè)務進行區(qū)分對待，設置不同的剩余帶寬門限值。當新呼叫或切換呼叫到達時，首先估計當前系統(tǒng)剩余的帶寬，然后根據(jù)不同類別業(yè)務與不同門限值進行比較，決定是否對該呼叫進行接納。最后通過仿真對門限值的不同設定進行了比較分析。

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.
