The present document describes the Sv interface between the Mobility Management Entity (MME) or Serving GPRS Support Node (SGSN) and 3GPP MSC server enhanced for SRVCC. Sv interface is used to support Inter-RAT handover from IMS based voice service over EPS to CS domain over 3GPP UTRAN/GERAN access or from UTRAN (HSPA) to 3GPP UTRAN/GERAN access and to support Inter-RAT handover from IMS based voice and video service over EPS to CS domain over 3GPP UTRAN access. Sv interface is also used to support Inter-RAT handover from voice service in CS domain over 3GPP UTRAN/GERAN access to IMS based service over LTE or UTRAN (HSPA).
If there is no specific indication, the term "MSC server" denotes 3GPP MSC server enhanced for SRVCC or 3GPP MSC server enhanced for vSRVCC as defined in TS 23.216.

4 General Description p. 6
This document describes the Sv interface related procedures, message parameters and protocol specifications. The Sv messages are based on GTP. The message format, IE coding, and protocol error handling for Sv is per GTP as specified in TS 29.274.
The general rules for IP address and UDP port number handling for the GTP messages on the Sv interface is per TS 29.274.
