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 of cellular mobile communication network system. In the transition from 2G to 3G, in order to ensure the continuity and smoothness of its transition, the handover problem between TD-SCDMA and GSM system is especially important. This article discusses in detail the problem of switching between TD-SCDMA / GSM dual-mode terminals and proposes solutions. The structure of the dual-mode terminal protocol stack is designed and the specific process of switching between them is studied. The process meets the requirements of the protocol.
