1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from an access and mobility management function (AMF) over non-3rd generation partnership project (3GPP) access, a notification message indicating 3GPP access;
identifying that the UE is capable of multiple universal subscriber identity modules (multi-USIM) and that the UE is not able to initiate a service request procedure over the 3GPP access in response to the notification message due to a UE implementation constraint; and
transmitting, to the AMF over the non-3GPP access, a notification response message indicating an inability of the UE to initiate the service request procedure.
