基于DCA非均匀负载蜂窝系统的最小呼损概率分析

Minimum call blocking probability for the DCA based cellular system with non-uniform traffic load

研究了基于动态信道分配(DCA)技术的蜂窝移动通信系统的呼叫损失概率问题,根据业务负载随时间和空间变化的不同特点,在一定的假设条件下,给出了DCA系统最小呼损概率的具体表达式,并在此基础上对分别采用固定信道分配(FCA)技术和DCA技术的系统性能进行了数值比较,所得结果直观地揭示了DCA技术在提高频谱效率和系统性能方面的优势。

This paper discusses the problem of call blocking probabilities for the DCA based cellular mobile communication systems. Under certain conditions, for the case of spatial and time varying traffic loads, explicit expresses for the minimum call blocking probability of the system have been obtained. Numerical comparisons of the performance between FCA and DCA based systems are also given, which reveal the ability to improve efficient usage of the frequence resources and the performance measurement for the system by using DCA technique.
