1. A method of handling a voice over long term evolution (VOLTE) call performed by a user equipment (UE) in a wireless network, the method comprising:
initiating the VOLTE call in a 4th generation (4G) network;
receiving configuration information for an inter radio access technology (I-RAT) measurement relating to the 4G network and a 5G network;
determining whether at least one of the UE or the 5G network does not support a voice over new radio (VoNR) call; and
controlling not to transmit a B1 measurement report while the VOLTE call is ongoing in response to determining that the at least one of the UE or the 5G network does not support the VoNR call.
