1. A method for performing voice call by a User Equipment (UE), comprises:
performing an Internet protocol Multimedia Subsystem (IMS) registration with a 5th Generation (5G) Base Station (BS);
detecting an event related to a voice call while the IMS registration is with the 5G BS;
comparing signal strength of a Wireless Fidelity (Wi-Fi) device and signal strength of a 4th Generation (4G) Base Station (BS) based on detecting the event related to the voice call;
shifting the IMS registration from the 5G BS to the Wi-Fi device, upon determining that the signal strength of the Wi-Fi device is greater than the signal strength of the 4G BS;
detecting a trigger for the voice call after shifting the IMS registration from the 5G BS to the Wi-Fi device; and
initiating the voice call over the Wi-Fi device, based on detecting the trigger.
