| 摘 要： | 提出了一种适合于多媒体码分多址系统的呼叫接纳控制策略,对于新呼叫和切换呼叫,接纳控制策略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。当新呼叫或切换呼叫到达时,首先确定新呼叫和切换呼叫的干扰门限,然后计算小区内多址干扰和小区间多址干扰,从而得到总干扰,将总干扰与干扰门限值进行比较,只有低于门限值的总干扰允许呼叫接入。

| Abstract: | A call admission control policy in wideband multimedia CDMA system is proposed in this paper. Different interference thresholds are set up for new calls and handoff calls. When new or handoff call arrives, interference threshold for new call and handoff call are firstly determined, then intra-cell and inter-cell interference are calculated, and the total interference is got. The total interference is compared with interference threshold, if the total interference is less than the threshold, the call is accepted. The policy improves the system performance with lower handoff call dropping probability. |
