摘  要:SRVCC(Single Radio Voice Call Continuity)是在用户通话过程中当用户离开LTE覆盖区域时将语音切换到2/3G网络,以保证语音业务连续性的方案,是移动网络演进过程中的一个过渡的语音解决方案。当中的关键网元SRVCC-MSC,其组网配置结构对SRVCC切换效率有着十分重要的影响,SRVCC切换时延则是差异最明显的性能指标之一。

AbstractSRVCC (single radiovoice call continuity) is a scheme to switch voice to2/3G network when the user leaves LTE coverage area in the process of user talk,so as to ensure voice service continuity,andis a transitional voice solution in the evolution process of mobile network. SRVCC-MSC,the key network element,has a very importantimpact on the efficiency of SRVCC handover. SRVCC handover delay is one of themost obvious performance indicators.
