Abstract: 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 present disclosure especially relates to method and system for providing simultaneous voice and data services in EN-DC capable UE.
The method includes the steps of determining whether a VOLTE service is available at the UE and automatically switching the UE from an EN-DC mode to a Single Radio Long Term Evolution (SRLTE)-ENDC mode in response to determining that the VOLTE is unavailable while the UE is operating in the EN-DC mode.
