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) entity, a paging request associated with a second network, the UE being in an active state on a first network;
identifying whether the paging request includes a first paging cause that forces the UE to service the paging request or a second paging cause indicating that the UE is allowed to drop the paging request;
in case that the paging request includes the first paging cause, transmitting, to the AMF entity, a service request message;
in case that the paging request includes the second paging cause, identifying whether performance reasons not to accept the paging request exist; and
in case that the performance reasons not to accept the paging request do not exist, transmitting, to the AMF entity, a service request message.
