一種蜂窩CDMA系統(tǒng)中的雙門(mén)限呼叫接納控制算法

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(wù)，新到達(dá)的語(yǔ)音業(yè)務(wù)，切換的語(yǔ)音業(yè)務(wù)進(jìn)行區(qū)分對(duì)待，設(shè)置不同的剩余帶寬門(mén)限值。當(dāng)新呼叫或切換呼叫到達(dá)時(shí)，首先估計(jì)當(dāng)前系統(tǒng)剩余的帶寬，然后根據(jù)不同類(lèi)別業(yè)務(wù)與不同門(mén)限值進(jìn)行比較，決定是否對(duì)該呼叫進(jìn)行接納。最后通過(guò)仿真對(duì)門(mén)限值的不同設(shè)定進(jìn)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.
