The invention provides a method for achieving single radio voice call continuity (SRVCC). The method comprises the following steps: user equipment (UE) establishes an IP multimedia core network subsystem (IMS) session anchored to a signaling anchor point with a remote user via a pocket switch (PS) network and transmits the media data of the IMS session via a first media path and a second media path; an enhanced mobile switch center (eMSC) sends a call request for switching the IMS session to the signaling anchor point after a switch request sent by the PS network and used for switching the IMS session into circuit switch (CS) network access is received; the signaling anchor point connects a third media path between the newly-built eMSC and the media anchor point with the second media path and sends a call response to the eMSC after the call request is received; and the eMSC connects the third media path with the CS media path between the UE and the eMSC after the call response is received, so that the UE can continue the call with the remote user via the CS media path, the third media path and the second media path.
