提出了宽带直扩码分多址中的一种呼叫允许控制策略 ,该策略对于新呼叫和切换呼叫的接纳设置了不同的干扰门限值 ,切换呼叫的门限高于新呼叫的门限。切换呼叫和新呼叫的干扰门限都随系统总干扰的变化而自适应变化。当有新呼叫或切换呼叫到达时 ,计算小区内多址干扰和小区间多址干扰 ,从而确定总干扰 ,并与干扰门限值进行比较 ,若低于门限值 ,则允许接入 ,否则拒绝 Proposed a call admission control strategy in wideband DSSS, which set different interference thresholds for the admission of new calls and handover calls, and the threshold of handover calls is higher than the threshold of new calls. Interference thresholds for handoff calls and new calls both vary adaptively as the total system interference changes. When a new call or handover call arrives, multiple intra-cell interference and inter-cell multiple access interference are calculated to determine the total interference and compared with the interference threshold, and if it is lower than the threshold, access is allowed; otherwise Refuse
