Disclosed herein is a method for establishing a connection between a terminal and a network entity in a wireless communication system including a Non-3GPP RAT. The method performed by a network entity comprises receiving, from the terminal, a first message including cell identification information indicating a last cell accessed by the terminal; running a first timer related to a paging when the network entity receives the first message; and transmitting a paging message to a cell corresponding to the cell identification information when the paging to the terminal is required before the running first timer expires.
