What is srvcc call flow

Question

Accepted Answer

SRVCC (Single Radio Voice Call Continuity) is a feature that allows a seamless handover of a voice call from LTE to 3G or 2G networks.

SRVCC is used in VoLTE (Voice over LTE) networks to ensure uninterrupted voice calls when moving between different network technologies.
The call flow involves the initiation of the handover process, transfer of the call session to the target network, and completion of the handover without any noticeable interruption to the call.
SRVCC is essential for providing a smooth transition for voice calls in mixed network environments.
Example: A user on a VoLTE call moves out of LTE coverage area and the call is seamlessly transferred to a 3G network using SRVCC.
