摘要

本文提出了C3G-A(第三代移动通信网络与Ad hoc网络的结合)系统。呼叫接纳控制(CAC)在无线通信网络的无线电资源管理中起着重要的作用。它根据一定的标准允许或拒绝呼叫到达连接请求。为了分析CAC在C3G-A系统中的性能,提出了马尔可夫链模型。然后给出了新呼叫阻塞概率和切换阻塞概率等性能计算公式。数值计算结果表明,C3G-A系统在新呼叫阻塞概率和切换阻塞概率方面优于传统的TD-SCDMA系统。

Performance analysis on Call Admission Control in C3G-A system
In this paper, C3G-A (Combining the third generation mobile communication network and Ad hoc network) system is presented. Call Admission Control (CAC) plays an important role in radio resource management of wireless communication networks. It permits or denies the call arrival connection requests based on the certain criteria. To analyze the performance of CAC in C3G-A system, Markov chain model is presented. Then the performance formulas such as new call blocking probability and handover blocking probability are developed. Numerical results show C3G-A system outperforms conventional TD-SCDMA system with respect to new call blocking probability and handover blocking probability.
