Abstract: A method and apparatus are provided for a handover (HO) by a Mobility Management Entity (MME). The method includes receiving, from an evolved Node B (eNB), a handover required message including information indicating whether the HO is for a circuit switched (CS) network or both a CS network and a packet switched (PS) network; splitting a voice bearer from another bearer based on the information; and transmitting a handover command message to the eNB.
