摘要 首先介绍了UMTS中的几种切换类型,然后就UMTS分组域到GSM/GPRS系统间切换(SGSN间),GSM/GPRS到UMTS分组域系统间切换(SGSN间),UMTS分组域到GSM/GPRS系统间切换(SGSN内),GSM/GPRS到UMTS分组域系统间切换(SGSN内)这4种切换过程中的数据缓存与转移的实现过程进行了详细论述,并进行了进一步深入的分析与比较,最后指出其优缺点。 This paper introduces some kinds of handover in UMTS,then discusses the procedures of data buffering and transferring in UMTS packet domain to GSM/GPRS inter - SGSN handover,GSM/GPRS to UMTS packet domain inter - SGSN handover, UMTS packet domain to GSM/GPRS intra - SGSN handover and GSM/GPRS to UMTS packet domain intra - SGSN handover in detail,which are further compared and analyzed. Finally points out the advantages and disadvantages.
