Abstract: Systems and methods for enhanced CSFB in a mobile operator core network are described. In one embodiment, a method of wireless communication by a user equipment (UE) is disclosed, comprising: directing a UE to move from an original cell using a first radio access technology (RAT) to a second cell using a second RAT to permit a circuit switched (CS) call; terminating the CS call at the second cell; determining whether the UE should reselect to the first RAT; identifying a target cell that may be in a same location as the second cell and that uses the first RAT; and sending the identified target cell to the UE within a field in a radio resource control message.
