receiving a paging request message from an access and mobility management function (AMF);
transmitting, to the AMF, a service request message while a session management message that is triggered by a session management function (SMF) is pending at the SMF, wherein the UE is in an idle state;
receiving, from the AMF, a service accept message corresponding to the service request message;
receiving, from the AMF, the session management message that is triggered by the SMF; and
after receiving the session management message, receiving a UE configuration update command message from the AMF, wherein a new 5th generation-global unique temporary identifier (5G-GUTI) is allocated after receiving the session management message.
