Claim:
1. A method of controlling an idle mode of a terminal in a wireless communication system, comprising: determining whether interference occurs between a first transceiver for cellular network and a second transceiver for ISM (industrial, scientific and medical) network that are heterogeneous communication modules of the terminal; and limiting, if the interference occurs between the heterogeneous communication modules, camping on a corresponding frequency of the communication module in which the interference occurs; limiting transmission and reception of the second transceiver in a sub-frame required to receive a paging message by the first transceiver; receiving the paging message after the limiting of camping; determining whether earthquake and tsunami warning system (ETWS) or commercial mobile alert system (CMAS) indication is included in the received paging message; confirming, if the indication is included in the paging message, scheduling information; and limiting transmission and reception of the communication module in which the interference occurs based on the scheduling information.
