1. A method by a terminal in a wireless communication system, the method comprising:
receiving from an Access Mobility Function (AMF) a first message comprising an extended discontinuous reception (DRX) cycle value;
receiving in a first cell a first system information, wherein the first system information comprises:
a parameter for modification period; and
information indicating extended DRX is allowed;
determining a reference paging cycle;
determining a paging frame based on the reference paging cycle;
monitoring in the first cell a paging occasion in the paging frame; and
receiving in the first cell a second message,
wherein the second message comprises:
a first bit related to system information modification; and
a second bit related to system information modification,
wherein a system information acquisition procedure is initiated at a first time point in case that:
the first bit of the second message is set to 1; and
the extended DRX cycle value is shorter than a modification period, and
wherein the system information acquisition procedure is initiated at a second time point in case that:
the second bit in the second message is set to 1; and
the extended DRX cycle value is longer than the modification period.
