Single-Radio Voice Call Continuity (SR-VCC) Voice calls need to be transferred across service
domains and radio access technologies with so called single-radio
Mobile Terminals that can not support simultaneous signaling on both E-UTRAN and UTRAN/GERAN radio channels
Single Radio voice call continuity and handoff E-UTRAN and UTRAN/GERAN E-UTRAN and CDMA2000 1xRTT

Conclusion
We present and explain these handover mechanisms, and identify the key motivation behind them
It is shown that when voice services are supported over E-UTRAN, the so-called SR-VCC mechanisms can be used to seamlessly hand over voice calls to legacy radio technologies UTRAN, GERAN, and 1xRTT
On the other hand, when no voice services are supported over E-UTRAN, CS fallback mechanisms can be used to transfer the user to a legacy radio access that supports conventional voice services over the CS domain
