科技迅速發(fā)展,席轉(zhuǎn)整個(gè)世界。科學(xué)技術(shù)變得越來越強(qiáng)大和準(zhǔn)確。事實(shí)上,在過去的幾十年中,無線通信技術(shù)發(fā)生了巨大的變化,從1980年的第一代開始,1990年的第二代,2000年代的第三代,到2010年的第四代無線通信技術(shù),并預(yù)計(jì)在2020年第五代無線通信技術(shù)將會(huì)來臨。并且從無線通信技術(shù)的發(fā)展來看,無線通信技術(shù)的發(fā)展變得越來越復(fù)雜和越來越智能化。如今,無線通信技術(shù)正處在發(fā)展過程中的巨大轉(zhuǎn)折點(diǎn),需要新的方向發(fā)展,即發(fā)展第五代無線網(wǎng)絡(luò)。原因是,目前的第四代無線移動(dòng)技術(shù)已經(jīng)到了理論上的標(biāo)準(zhǔn)化階段,未來幾年將不再適應(yīng)或支持QoS以及對(duì)無線技術(shù)需求中的資源進(jìn)行管理,因此,具有非凡的功能的5G無線網(wǎng)絡(luò),它將成為4G提供QoS的邏輯替代品。然而,本文重點(diǎn)研究了無線網(wǎng)絡(luò)中的重要呼叫接納控制（CAC）方案,該方案是使用預(yù)定義算法來保證無線或移動(dòng)通信網(wǎng)絡(luò)中的效率,靈活和可靠的服務(wù)質(zhì)量（QoS）的有效機(jī)制。為了最小化呼叫連接的通信量或者數(shù)量并且具有控制網(wǎng)絡(luò)擁塞以提供新來電或者現(xiàn)有呼叫中的服務(wù)質(zhì)量（QoS）需求,引入了對(duì)呼叫許可控制的方法。為了獲得更好的效果,我使用了Riverbed（OPNET）Modeler 9....
