摘要
介绍GPRS技术和智能网技术在GSM-R网络中的应用,指出了在GPRS网络上架构智能网的必要性。针对现有的基于SGSN触发和GGSN触发的2种实现方案,并结合GSM-R网络对GPRS应用的需求,对这2种实现方案的性能进行了比较,得出基于GGSN触发的实现方案更适合GSM-R网络。
In this paper, we present the applications of GPRS technology and intelligent network technology in the GSM-R network and point out the necessity of constructing intelligent network over GPRS network, Then we introduce two present implement solutions based on SGSN Triggering and based on GGSN Triggering, and compare the two solutions based on their performances in the GSM-R application, Finally, we conclude that the latter is better for GSM-R application.
