Firstly , i introducesome representative cac arithmetic in mobile communication networks and somecommoncac arithmetic in cdmasystems . these arithmetichavetheir own differentcharacters , and a practical cac needs consider all kinds of factors synthetically . so , inthe base of the above arithmetic , i put forward two improved arithmetic which are aimproved cac arithmetic bases on mbgc and a new cac arithmetic bases on gos , consideringsoft capacitycharacteristicofcdmasystems , intheend , iproposeakindof arithmetic based on different interference thresholds , which gives the differentinterference thresholds aimed at the different services 接下來則重點討論了呼叫接納控制算法,先介紹了移動通信網(wǎng)絡(luò)中的一些較具代表性的呼叫接納控制算法和cdma系統(tǒng)中的常用算法,這些cac算法各有不同的側(cè)重點,一個實用的cac需要綜合考慮各方面的因素,所以在上述算法的基礎(chǔ)上,提出了改進算法:基于mbgc (可移動邊界保護信道)的呼叫接納控制算法和基于gos (服務(wù)等級)的呼叫接納控制算法。
