Abstract
A method and apparatus are provided for handing over from a Long Term Evolution (LTE) network to a Circuit Switching (CS) network by a call manager in a wireless communication system. The method includes receiving, from an Enhanced Node B (ENB) of the LTE network, a handover required message for a Packet Switching (PS) to CS handover from the LTE network to the CS network, when the PS to CS handover is decided based on measurement reports of a User Equipment (UE); sending, to a Mobile Switching Center (MSC) of the CS network, a PS to CS handover request message including an International mobile subscriber identity (IMSI) for identifying the UE and a target IDentifier (ID) for a target cell of the CS network; receiving a PS to CS handover response message from the MSC; and sending, to the UE via the ENB, a handover command message.
