摘要
TD-SCDMA系统是第三代蜂窝移动通信网络系统,在由2G向3G的过渡阶段,为了保证其过渡的连续性和平滑性,TD-SCDMA与GSM系统间的切换问题显得尤为重要。本文详细讨论了TD-SCDMA/GSM双模终端在两种制式间切换的问题并提出解决方法,设计双模终端协议栈结构,并研究它们相互切换的具体过程,过程符合协议要求。
TD-SCDMA system is the third-generation cellar mobile telecommunication system, and in the transitional stage from 2G to 3G, for the handover between TD-SCDMA and GSM systems is very important in guaranteeing the succession and smoothing in the process of the transition. The handover between two systems of user equipment in TD-SCDMA and GSM systems has become the focus for research, and a solution is proposed in this paper. And the structure of UE protocol stack in TD-SCDMA and GSM systems is designed; the process of handover between the two systems has been studied, and the experiment shows that the process conforms to the standard of protocol.
