分组数据业务自身的特性给数据容量的计算带来了更大的复杂性,传统的CDMA无线容量规划是根据话务量折算出数据业务吞吐量。本文探讨一种新的CDMA容量规划思路,即先通过仿真研究分析CDMA2000 1x分组数据业务的性能,输出各种速率业务信道的数量的概率分布,再通过爱尔兰排队系统模型C计算得到系统的数据容量。
The characteristics of packet data service bring greater complexity to the calculation of data capacity. The traditional CDMA wireless capacity planning is based on traffic volume data service throughput. In this paper, a new idea of CDMA capacity planning is discussed. First, the performance of CDMA2000 1x packetized data services is analyzed by simulation and the probability distribution of the number of traffic channels of various rates is output. Then the data capacity of the system is calculated by the Irish queuing system model C .
