| 摘 要： | 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

| Abstract: | A policy of call admission control in Wideband DS-CDMA system was proposed.Different interference thresholds were set up for new calls and handoff calls in the policy. The interference threshold for handoff calls was higher than that of new calls. When new or handoff call arrived, intra-cell and inter-cell interference were firstly calculated, then total interference was got. Comparing total interference with interference threshold, if total interference was less than the threshold, the call was accepted, else, it was rejected. |
