DEVICE AND METHOD FOR MERGING CIRCUIT SWITCHED CALLS AND PACKET SWITCHED CALLS IN USER EQUIPMENT

摘要

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method comprising: establishing a first call with a second UE, wherein the first call is one of a Circuit-Switched (CS) call and a Packet-Switched (PS) call; establishing a second call with a third UE while the first call is in an active state, wherein the second call is one of a CS call and a PS call; and merging the first call and the second call on the basis of a specific event.
