Abstract
Methods and apparatuses are provided for providing a voice call service in a Circuit Switching (CS) domain to a User Equipment (UE) being in a Packet Switching (PS) domain in a mobile communication system. A first message for paging to provide the voice call service in the CS domain to the UE is sent to an evolved Node B (eNB) in the PS domain. A second message including a cause associated with a domain change from the PS domain to the CS domain, is received from the eNB. A third message requesting suspension of the service being provided to the UE in the PS domain, is sent to a gateway in the PS domain.
