Abstract

The General Packet Radio Service (GPRS) is designed for transmitting packet data and supposed to take its radio resource from the pool of channels unused by GSM voice services. Obviously, the introduction of GPRS affects on the voice services. In this paper, the outage probability of non-frequency hopping and frequency hopping systems with different frequency reuse factor has been calculated in order to investigate those effects. The number of unused voice channels allocated to GPRS depends on the difference between the outage level of the existing GSM network and the maximum acceptable level. For both non-frequency hopping and frequency hopping systems, GPRS affects the QoS of voice services of the network with small reuse factor are higher than that of the network with large reuse factor. GPRS will reduce the cell service area, but the reduction percentage of the cell service area for the system with a small reuse factor is higher than that for the system with a large reuse factor.

GPRS在GSM语音服务上的中断概率

通用分组无线业务(GPRS)设计用于传输分组数据，并从GSM语音业务未使用的信道池中获取其无线电资源。显然，GPRS的引入会对语音业务产生影响。本文计算了非跳频系统和具有不同频率复用因子的跳频系统的中断概率，以研究这些影响。分配给GPRS的未使用语音信道的数量取决于现有GSM网络的中断级别与最大可接受级别之间的差异。无论对于非跳频系统还是跳频系统，GPRS对复用系数小的网络语音业务的QoS影响都大于复用系数大的网络。GPRS会减少小区服务面积，但是复用系数小的系统小区服务面积的减少百分比要高于复用系数大的系统小区服务面积的减少百分比。
