GPRS系统容量分析

GPRS capacity analysis

随着移动通信技术的发展,GPRS通信技术以其独特的优点迅速得到了广泛的应用,GPRS系统容量规划是当前其发展需要考虑的重要因素之一。该文简述了GPRS通用分组无线传输业务及其特点,然后重点根据具体的话务量模型对GPRS系统的容量进行了分析,并提出了系统容量计算公式。分析计算结果表明,在满足一定呼损率和业务质量的条件下,GPRS的引入可以大大提高GSM系统的信道利用率。

With the development of mobile communication, GPRS is widely being used because of its particular advantages. Presently one of the important factors of developing GPRS is its capacity programming. In this paper introduced the GPRS transportation net- works and its characters, then stressed on analyzing GPRS capacity based on the traffic model, and put forward the formula for calculating it. The resuhs indicated that the using of GPRS can mostly enhance the channel efficiency of GSM in the case of satisfying the necessary percent of call lost and service qualities.
