Abstract
Embodiments herein provide a method for performing voice call performance by a user equipment (UE). A voice call is preferred for a cellular network over a Wi-Fi network, an IMS is registered over a 5G BS, the 5G BS is not supported for the voice call, and a Wi-Fi device and a 4G BS are supported for the voice call. The method includes: detecting an event related to the voice call; comparing signal strength of the Wi-Fi device and signal strength of the 4G BS; shifting an 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; and initiating the voice call over the Wi-Fi device upon detecting a trigger for the voice call.
