1. A method performed by an access and mobility function (AMF) entity in a wireless communication system, the method comprising:
performing with a multi-subscriber identity module (SIM) user equipment (UE), a first registration procedure associated with registering a first SIM of the multi-SIM UE;
receiving, from the multi-SIM UE, a second registration request message associated with registering a second SIM of the multi-SIM UE, wherein the second registration request message includes a globally unique temporary identifier (GUTI) allocated to the first SIM via the first registration procedure; and
transmitting, to the multi-SIM UE, information indicating that a first context of the first SIM and a second context of the second SIM are stored in the same AMF entity,
wherein the information indicating that the first context and the second context are stored in the same AMF entity is associated with not monitoring a paging channel in case that one of the first SIM and the second SIM is in a connected state.
