Voice call continuity implementation method and device, and storage medium

The embodiment of the invention discloses a voice call continuity implementation method, an MSC server, an AMF and a computer readable storage medium. The method comprises the following steps that: amobile switching center (MSC) server receives a switching request message from a packet switching (PS) domain to a circuit switching (CS) domain sent by an access and mobility control function (AMF) through a preset interface or a mobility management entity (MME) for interface conversion; and the MSC server executes a single radio voice and video call continuity SRVCC switching process according to the switching request message from the PS domain to the CS domain. According to the embodiment of the invention, the interface is newly added between the AMF and the eMSC or the MME for interface conversion is deployed between the AMF and the eMSC, so that the voice call of the VOR can be directly switched from 5G to a 2/3G wireless network, and the voice call continuity is further realized. 本申请实施例公开一种语音呼叫连续性的实现方法、MSC服务
