Abstract
The present disclosure relates to a 5G or pre-5G communication system for supporting higher data transmission rates than 4G communication systems such as LTE. The present invention relates to a method and device for supporting voice handover in a wireless communication system and increasing service quality in a mobile communication system, and more specifically, to a method for a UE connected to a first network to communicate with a network in a wireless communication system, the method comprising the steps of: connecting a voice call to a second network; receiving, from a base station of the second network, a message including control information for controlling wireless access of the UE; and using the control information to determine the radio access technology (RAT) to be used and the PLMN to be accessed after the voice call is completed, wherein the first network and the second network communicate using different RATs, and the voice call is connected to the second network by circuit switching (CS).
