1. A method for a user equipment (UE) for performing a paging reception, the method comprising:
registering to a first network comprising an Evolved Packet Core (EPC) network and a second network comprising a 5G core (5GC) network using a first Universal Subscriber Identity Module (USIM) and a second USIM, respectively;
selecting one of the first network and the second network to prevent a paging collision on the first network and the second network;
when the first network is selected:
determining, based on a current UE identity (ID), an offset value for a paging occasion calculation;
transmitting, by the first USIM, to the first network, the offset value via a tracking area update procedure or via an attach procedure;
receiving, by the first USIM, from the first network, a configured offset value for the paging occasion calculation;
forwarding, by a Non-Access-Stratum (NAS) layer of the UE, to a lower layer of the UE, the configured offset value;
determining a first UE ID based on the configured offset value; and
performing the paging reception based on the first UE ID; and
when the second network is selected:
initiating a UE ID reassignment procedure with the second network, the UE ID reassignment procedure comprising a registration procedure;
receiving, by the second USIM, from an Access and Mobility Management Function (AMF) of the second network, a second UE ID via the UE ID reassignment procedure;
forwarding, by the NAS layer of the UE, to the lower layer of the UE, the second UE ID; and
performing the paging reception based on the second UE ID.
