数据用户在GPRS与TD-SCDMA系统间的切换过程

Handover process between GPRS and TD-SCDMA for data users

在GSM/GPRS向TD-SCDMA平滑升级的过程中,不同的网络演进方案将导致系统间业务实现过程有所不同,使得网间信令的跟踪与测试变得更加复杂,对TD-SCDMA信令测试仪的研发也提出了更高的要求。针对TD-SCDMA核心网演进过程中的几种典型网络结构,以数据用户在GPRS与TD-SCDMA系统间的切换为例,进行信令过程的研究与分析,提出了一种TD-SCDMA信令测试仪对相关过程的跟踪测试方案。该方案对研究TD-SCDMA信令测试技术有重要的参考价值。

During the process of smooth upgrading from GSM/GPRS to TD-SCDMA, different network evolving scheme causes different implementing process of service inter-systems, which makes the tracing and testing of internctwork signalling become more complicated. Aiming at several typical network structures of TD-SCDMA core network, this paper presents a tracing and testing scheme of TD-SCDMA signalling tester to different procedure by researching and analyzing the signalling service procedures of data user＇s handover between GPRS and TDSCDMA. It is proved that this scheme is of very important reference value for researching TD-SCDMA signalling testing technology.
