摘要：
Technology for transcoding avoidance during a single radio voice call continuity (SRVCC) procedure is disclosed. In an example, a mobile switching center (MSC) can include circuitry configured to: receive from a mobility management entity (MME) in a SRVCC packet switch (PS) to circuit switched (CS) request message, selected CODEC information for a selected CODEC used for a user equipment (UE) in an internet protocol (IP) Multimedia Subsystem (IMS) over long term evolution (LTE) system; and communicate the selected CODEC information to a target MSC to enable the target MSC to identify the selected CODEC for the UE to allow the selected CODEC to be used in the CS domain.
