摘要

针对宽带码分多址(CDMA)蜂窝系统,提出了一种基于模糊干扰的呼叫接纳控制(CAC)方案。模糊CAC首先估计新到达的移动站的有效带宽和移动信息,然后根据估计值和系统状态做出接受或拒绝移动站连接请求的决定。从新呼叫阻塞概率、切换呼叫丢失概率、中断概率和资源利用率等方面对所提出的模糊CAC方案进行了数值验证。

Call admission control in wideband CDMA cellular networks by using fuzzy logic
A novel call admission control (CAC) scheme using fuzzy interference for a wideband code division multiple access (CDMA) cellular system is proposed. The fuzzy CAC first estimates the newly arriving mobile station's (MS) effective bandwidth and its mobility information, and then makes a decision to accept or reject the MS's connection request based on the estimates and the system status. Numerical results are given to demonstrate the performance of the proposed fuzzy CAC scheme in terms of new call blocking probability, handoff call dropping probability, outage probability and resource utilization.
